Indirect heating type rotary dryer 
This is an indirect heating type of rotary dryer that brings materials into indirect contact with heating medium to provide heat exchanging. 
The indirect heating type of rotary dryer is classified into external heating rotary dryer and steam tube dryer, which are applied for the following conditions. 

If you use materials that are easily affected by contact with combustion gas.

If you need to minimize the amount of exhaust gas from the dryer.

If you use materials that are apt to produce dust.

If you use materials that are easily affected by oxidation.

If you need to recover volatile component.

Construction

The main unit of the rotary dryer is an inclined shell supported by four rollers. Materials, which are fed through one end of the shell, move inside the shell along the inclination of the shell and through the rotary movement and are discharged from the other end. Materials, while moving inside the shell, are lifted up by a lifter incorporated in the shell. Then, the materials fall evenly in the shell space and exchange heat with the hot air flowing through the space to dry. Depending on the method of providing hot air for the materials, this dryer is classified into two types, that is, concurrent flow drying type by which the hot air and materials flow in the same direction and countercurrent flow drying type by which they flow in the opposite direction.
Lifter
The lifter is the most critical part having an influence on the performance of the dryer, which provides uniform dispersion of materials in the shell space. Any of the constructions shown below is used according to the physical properties of materials. Furthermore, spiral lifters designed with consideration of forced feeding of materials are used for the material feeding end.

Adjustment of residence time
By providing dams according to the applications, the materials residence time can be adjusted.

Prevention of adhesion and accumulation
In order to handle materials of high adhesive property, chains are provided in the shell or a hammering unit is provided externally on the shell, thus preventing material adhesion and accumulation.

Concurrent flow and countercurrent flow
Concurrent flow drying type
With the concurrent flow drying type, the materials move and the hot air flows in the same direction. Therefore, the hot air of the highest applicable temperature comes in contact with materials of the lowest applicable temperature at the end of the material inlet of the rotary shell. Normally, the concurrent flow drying type is used for the following conditions.

Countercurrent flow drying type
With the countercurrent flow drying type, the relation of flow direction and temperature between the hot air and the materials becomes reverse equivalent of the concurrent flow drying type. Therefore, this type is used especially in the case that low-moisture products are required, taking advantage of its characteristic that the hot air of the highest applicable temperature comes in contact with materials of the lowest moisture at the end of the material outlet.

The Kurimoto Solvent Recovery System is a fixed bed type of flue gas treatment equipment using granulated active carbon, which has been developed for the purpose of recovering organic solvent contained in the flue gas. By passing the solvent-containing gas through the granulated active carbon layer, the solvent is adsorbed to the active carbon to exhaust clean air. By blowing vapor into the active carbon layer after the solvent is adsorbed, the solvent is isolated from the active carbon, and recovered after condensation and separation. 

Features

Providing a high degree of elimination efficiency.

Supporting for large changes in inlet concentration.

Trouble-free operation.

A large amount of know-how and extensive experience.

Enabling treatment in the range from small capacity to large capacity.

Less running costs, compared to other solvent recovery systems.

Application

Chlorine base organic solvent

• Solvent and monomer generated from solution polymerization lines.
• Industrial cleaning agent such as methylene chloride, trichloroethylene, and tetrachloroethylene

Chlorofluorocarbon base solvent

• Heat insulation chlorofluorocarbon (CFC-11and HCFC-141b)
• CFC-113

Hydrocarbon base organic solvent

• Non water base
  Benzene, toluene, xylene, styrene, naphtha, kerosene, heptane, and others
• Water base
  Methanol, ethanol, acetone, methyl ethyl ketone, propanol, methyl acetate, ethyl acetate, butyl acetate, and others

Operating Process

The Kurimoto Solvent Recovery System enables the elimination and recovery of solvent contained in flue gas by performing the following processes in order of “Adsorption”, “Isolation”, and “Drying”. By using two active carbon adsorption towers, the continuous treatment of flue gas is enabled.

The solvent-containing gas is sucked by the blower. When the gas passes through the granulated active carbon layer, the solvent is adsorbed to the active carbon, where it turns into clean air to be exhausted.

Steam is blown into the adsorption tower from its bottom to purge the solvent adsorbed to the active carbon. The isolated solvent vapor passes through the condenser where it is liquefied, and it is recovered by gravity separation through the separator.

The active carbon, which has got wet in the isolation process, is dried by hot air generated through the steam air heater and, then, cooled by air of ambient temperature.

Specification

1. The Kurimoto Solvent Recovery System is of unit type. Therefore, the system can support for applications requiring high concentration and large air quantity in accordance with the combination.
2. Each type has the following models.

This machine is an indirect heating type of rotary kiln using electricity, heavy oil, or gas as the heat source. The shell, due to its equilateral hexagonal cross section, minimizes the “shear” of the material layer to provide a sharp distribution of residence time, enabling you to get stable and high quality products of uneven firing.

Features

Equilateral hexagonal shell employed (Refer to Figure-1.)
Compared to cylindrical shell, this shall provides less “shear” of the material layer, a sharp distribution of residence time, and less uneven calcining, increasing the material holding ratio to make the equipment compact in size.

(Figure-1 Comparison of kiln action)

Introduction of superb air sealing performance and special sealing construction enables sealing up to a maximum of pressure of kiln internal pressure±500Pa.

Besides oxidized (i.e., in the air) or neutral (i.e., nitrogen gas or carbon dioxide gas) gas, reducing gas can be used.
Carrier gas or reaction gas can be charged thanks to the improved sealing performance.

Severe calcining temperature control enabled
The calcining temperature is directly measured with sheathed thermocouples inserted in the material layer.
Introducing the multi-chamber type of electric furnace enables independent temperature control of each chamber.
The material temperature is selectable up to a maximum of 1000ºC. Furthermore, if you use gas or heavy oil as the heat source, please introduce the hot air circulation system for energy savings.

Direct heating type rotary dryer 
This is a direct heating type of dryer that brings materials into direct contact with hot air to dry them by lifting them up inside the rotary shell

If you use materials that are easily affected by contact with combustion gas.

If you need to minimize the amount of exhaust gas from the dryer.

If you use materials that are apt to produce dust.

If you use materials that are easily affected by oxidation.

If you need to recover volatile component.

Construction

The main unit of the rotary dryer is an inclined shell supported by four rollers. Materials, which are fed through one end of the shell, move inside the shell along the inclination of the shell and through the rotary movement and are discharged from the other end. Materials, while moving inside the shell, are lifted up by a lifter incorporated in the shell. Then, the materials fall evenly in the shell space and exchange heat with the hot air flowing through the space to dry. Depending on the method of providing hot air for the materials, this dryer is classified into two types, that is, concurrent flow drying type by which the hot air and materials flow in the same direction and countercurrent flow drying type by which they flow in the opposite direction.
Lifter
The lifter is the most critical part having an influence on the performance of the dryer, which provides uniform dispersion of materials in the shell space. Any of the constructions shown below is used according to the physical properties of materials. Furthermore, spiral lifters designed with consideration of forced feeding of materials are used for the material feeding end.

Adjustment of residence time
By providing dams according to the applications, the materials residence time can be adjusted.

Prevention of adhesion and accumulation
In order to handle materials of high adhesive property, chains are provided in the shell or a hammering unit is provided externally on the shell, thus preventing material adhesion and accumulation.

Concurrent flow and countercurrent flow
Concurrent flow drying type
With the concurrent flow drying type, the materials move and the hot air flows in the same direction. Therefore, the hot air of the highest applicable temperature comes in contact with materials of the lowest applicable temperature at the end of the material inlet of the rotary shell. Normally, the concurrent flow drying type is used for the following conditions.

Countercurrent flow drying type
With the countercurrent flow drying type, the relation of flow direction and temperature between the hot air and the materials becomes reverse equivalent of the concurrent flow drying type. Therefore, this type is used especially in the case that low-moisture products are required, taking advantage of its characteristic that the hot air of the highest applicable temperature comes in contact with materials of the lowest moisture at the end of the material outlet.

Application

Concurrent flow drying type

Countercurrent flow drying type
