Description

Technical Field

[0001] The utility model relates to the technical field of machine-made carbon energy recovery, in particular to a carbonization tail gas recovery device. Background Art

[0002] Mechanism charcoal, also known as artificial charcoal, regenerated charcoal, and smokeless clean charcoal, is a carbonaceous rod made by extruding wood chips. The raw materials of charcoal rods are widely available. Rice husks, peanut shells, cotton shells, corn cobs, corn stalks, sorghum stalks, etc. can all be used as raw materials to produce charcoal rods. Sawdust, wood shavings, and bamboo chips are the best. It has high density, high calorific value, is smokeless, odorless, pollution-free, non-explosive, and flammable. It is an internationally recognized green and environmentally friendly product. However, there are still limitations on the charcoal rod making machine devices for making bamboo chips on the market. Carbonization kiln refers to equipment that can carbonize raw materials such as wood.

[0003] In the process of carbonization of mechanical charcoal, the prior art will emit a large amount of high-temperature exhaust gas, which contains a large amount of coal powder. In the prior art, the waste heat of the high-temperature exhaust gas is seldom utilized, and the exhaust gas is usually only discharged into the atmosphere after being incinerated. In the process of discharging into the atmosphere, a large amount of energy generated by the incineration is also lost and wasted, resulting in energy waste. Summary of the invention

[0004] In view of this, the purpose of the utility model is to provide a carbonization tail gas recovery device that can realize the recovery and reuse of tail gas during carbonization of machine-made charcoal in a carbonization kiln.

[0005] The utility model is realized by the following method: a carbonization tail gas recovery device comprises a filter bin body, the right side surface of the filter bin body is connected to an outlet pipe connected to the outlet of the carbonization kiln, a filter element for filtering gas is arranged in the filter bin body, a plurality of heating tubes are arranged at equal distances in the left end of the inner wall of the filter bin body, and the filter bin body is connected to the carbonization kiln via a pipeline.

[0006] Furthermore, a pressure pump is provided on the pipeline, and a temperature sensor is provided at the right end of the upper surface of the pipeline.

[0007] Furthermore, the filter element includes an activated carbon filter plate, and support frames are drawable on both left and right ends of the front face of the filter chamber body, the activated carbon filter plate is arranged in the support frame, and a drawable groove is opened on the right end of the front face of the support frame.

[0008] The beneficial effects of the utility model are as follows: the utility model adds a filter element, an air outlet pipe and a pipeline to the device, which can filter the high-temperature exhaust gas generated during carbonization in the carbonization kiln, and then transport it to the carbonization kiln, so that the temperature in the carbonization kiln can be raised again, ensuring the reuse of energy, and can also preheat the carbonization kiln to facilitate subsequent carbonization; the utility model has a simple structure and is easy to operate, can effectively save manpower and material resources, and improve work efficiency.
