Hereinafter, the operating state of the present invention energy-saving multi-stage rotary kiln having such a configuration.

First, when the raw material is injected into the raw material storage hopper 110 of the raw material supply device 100, the raw material is injected into the raw material storage hopper 110 is injected into the screw conveyor 120, the screw conveyor 120 The injected raw material is gradually moved by the rotation of the screw, and is injected into the raw material loading chute 130, and the raw material introduced into the raw material loading chute 130 slides down along the slope of the raw material charging chute 130 while the rotary kiln distillation unit 200 ) Is introduced into the inlet 211 of the rotary kiln reactor 210 located at the top.

On the other hand, the rotary kiln reactor 210 having a structure of two or more layers is rotated in one direction by the driving motor, respectively, and in the heating furnace 221 by the operation of the burner 222 of the heating device 220. The rotary kiln reactor 210 remains heated by the high temperature atmosphere.

The raw material introduced into the heated top rotary kiln reactor 210 is moved little by little from the inlet port 211 to the outlet port 212 by the rotational force of the rotary kiln reactor 210, while being heated by the heating device 220. Indirect heating is gradually dried (pyrolyzed), and the raw material in the dry stream discharged from the outlet 212 of the uppermost rotary kiln reactor 210 is in the lower portion of the rotary kiln reactor 210 located through the raw material transfer chute 230. As it is introduced into the inlet 221, it goes through a dry distillation (pyrolysis) process by the heating device 230 again. In this way, the raw materials are completely dried while moving to the outlet of the rotary kiln reactor 210 located at the bottom, and the dried raw materials are stored in the product storage box.

On the other hand, when the raw material passing through the rotary kiln reactor 210 of two or more stages is dried by the heating device 220, the raw material generating gas is generated through the thermal decomposition process of the raw material, the raw material generating gas is a flammable gas generated gas The exhaust gas 310 passes through the first dust removal pipe 320 and the second dust removal pipe 330 to discharge impurities such as dust and tar, and the purified combustible gas is heated through the gas inlet pipe 340. It is introduced into the generated gas combustion burner 222a provided in the 220 and reused as a fuel for heating the rotary kiln 210.

That is, the raw material generating gas generated in the rotary kiln reactor 210 is exhausted to the first dust removing pipe 320 through the generating gas discharge pipe 310 of the raw material generating gas purification apparatus 300 connected to the chamber 240. do. At this time, the raw material generating gas introduced into the first dust removing pipe 320 moves to the upper portion of the first dust removing pipe 320 to drop dust and tar, which are large particles, to the bottom to remove impurities such as dust and tar. do.

Next, the raw material generating gas exhausted to the first dust removing pipe 320 is exhausted to the second dust removing pipe 330 and then quickly generated gas provided to the heating device 220 through the generated gas inlet pipe 340. It is introduced into the combustion crater 222a and reused as fuel in the heating furnace 221. At this time, the raw material generating gas passing through the second dust removing pipe 330 drops impurities such as dust and tar included in the raw material generating gas in the process of flowing into the generated gas inlet pipe 340, and thus, the second dust Remove tar, etc.

As such, the raw material generating gas from which dust and tar are removed secondly is introduced into the generating gas combustion crater 222a through the generating gas inlet pipe 340 through the generating gas inlet pipe 340 to heat the rotary kiln 210. It is used as a heat source.

Therefore, the energy-saving multi-stage rotary kiln of the present invention having such a configuration and action is formed by connecting the rotary kiln in multiple stages and indirectly heated by a heating device, respectively, greatly increasing the ease of fabrication and installation, thereby increasing the efficiency of dry distillation. It is possible to greatly reduce energy by minimizing external fuel input for operation of rotary kilns by collecting and refining combustible gases generated during dry distillation (pyrolysis) of raw materials and reusing them as fuels in furnaces that heat rotary kilns. .

On the other hand, in the case of the rotary kiln of the first stage described in the prior art, it is difficult to give a constant reaction time for each zone according to the raw material characteristics, and it is difficult to give a constant amount of production according to raw material characteristics. Not easy to

That is, in particular, if the first stage rotary kiln according to the prior art should maintain the temperature of the drying zone zone 500 ℃ ~ 600 ℃, heat energy in the zone heat / dry and pre-heating and cooling zone, the actual dry cod Both ends of the liver are kept at a temperature lower than the desired temperature, resulting in a shortening of the dry zone.

In addition, the cooling section has a main purpose of dropping the temperature in order to smoothly handle the dry distillation products, the cooling efficiency is reduced due to the heat energy transferred from the firing or drying zone, a separate cooling process and system must be provided. do.

With this problem, the energy-saving multi-stage rotary kiln of the present invention can distinguish between drying / preheating, dry distillation, and cooling zones for each rotary kiln in the multi-stage, and thus it is possible to give a constant reaction time according to the characteristics of raw materials, and to control the production volume. And easy to secure.

That is, temperature control is easy for each region, and reaction time and conditions may be differently applied as necessary.

For example, in the case of drying / preheating zone, if the reaction temperature is increased as needed, it can be utilized as a distillation zone and it can be utilized as an extension of the distillation zone when production is required. It can be maintained, so that not only can control the production amount by varying the rotary kiln rotation speed, it is also advantageous for the production of homogeneous products.

In addition, in the case of the cooling stand, it is possible to operate semi-finished products discharged from the distillation stand only for cooling purposes, such as operating a circular rotary kiln without exposure to the combustion chamber in the air or operating in a water-cooled state, thereby increasing cooling efficiency.
