Problems solved by technology
[0004] At present, the operation mode of the 5-chamber structure gas oxidation device often has abnormal temperature gradients in each chamber. The ability to adjust the temperature gradient by changing the reversing time is very limited. When the load is high, such as gas source or other When the factors fluctuate, the abnormal temperature gradient may endanger the safety of the regenerator operation

Embodiment Construction
[0021] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0022] The reference signs in the accompanying drawings of the specification include:
[0023] Drainage pump station 11, low-concentration gas delivery system 12, blender 13, return air shaft diffusion tower 14, main fan 15, start-up combustion-supporting device 16, combustion chamber 17, waste heat boiler 18, heating room 19, bathroom 20, Blowing fan 21, chimney 22, regenerator 23, inlet valve 24, outlet valve 25, purge valve 26.
[0024] The five-chamber structure gas oxidation device of the present invention adopts the method of sequentially switching operation of five circulation modes, and each circulation mode is divided into five operating states, and the operating time of each operating state is regulated and controlled by a reversing valve. The regenerators are represented by A, B, C, D and E from left to right to represent five r...

The invention belongs to the field of gas destroying treatment methods or devices, and particularly relates to a five-chamber structure gas oxidization device and a running method thereof. The five-chamber structure gas oxidization device comprises five separated heat storage chambers and a combustion chamber communicating with the heat storage chambers. Heat storage ceramic is arranged in the heat storage chambers, a starting combustion supporting device is arranged on the combustion chamber. A waste heat boiler is connected with the combustion chamber through a pipeline. A conveying pipeline is arranged below the heat storage chambers and provided with two reversing valves. A main draught fan and a chimney are arranged on the left side and the right side of the conveying pipeline correspondingly. An air inlet valve, a purge valve and an air outlet valve are arranged between each heat storage chamber and the conveying pipeline. The conveying pipeline communicates with pipelines where the air inlet valves and the air outlet valves are located. A purge draught fan is arranged below the heat storage chambers, an air outlet of the purge draught fan is connected with an air blowing pipeline, and the air blowing pipeline communicates with pipelines where the purge valves are located. The problem that when a gas source or other factors in the five-chamber structure gas oxidization device fluctuate, running safety of the heat storage chambers is possibly endangered due to abnormality of the temperature gradient is solved.
Description
technical field [0001] The invention belongs to the field of gas destruction treatment methods or devices, and in particular relates to a gas oxidation device with a five-chamber structure and an operating method thereof. Background technique [0002] Coal mine gas (also known as "coalbed methane") is an unconventional natural gas that exists in the coal seam and its surrounding rocks, exists in an adsorbed or free state, and mainly consists of methane. my country is rich in coalbed methane resources. According to a new round of resource evaluation, my country's coalbed methane resources at depths below 2,000 meters are about 36.81 trillion cubic meters, equivalent to 49 billion tons of standard coal, ranking third in the world. However, the reality that cannot be ignored in the current development of my country's coalbed methane development industry is that the gas production of a single coalbed methane well is too low, the economic benefits are low, and the industry is fac...
