The invention provides an integrated system capable of realizing full utilization of coal mine gas, and relates to the field of energy utilization. The invention aims to solve the problem that when a heat storage device in an existing integrated system for capable of realizing full utilization of gas is used, solid particles cannot be purified in an auxiliary mode and cannot be collected in a centralized mode. The integrated system provided by the invention comprises: an inner part, wherein the inner part is embedded into a through groove, the inner part comprises a sealing plate, the sealing plate is composed of two wedge-shaped plates, and the sealing plate is fixed in a rectangular groove of a filter plate; and a pressing plate, which is embedded in the inner bin. According to the invention, steam enters the interior of a passing groove to circulate; the sealing plate seals a rectangular hole of the filter plate, so the steam cannot circulate at the first time, the filter plate can be stressed to move together with a moving part, the moving part can compress filter cotton and a supporting plate, and the density of the filter cotton is reduced; and meanwhile, the steam pushes the sealing plate to be opened, so the steam can pass through, and solid particles can enter the filter cotton.
Description
technical field [0001] The invention belongs to the technical field of energy utilization, and more specifically relates to an integrated system for full utilization of coal mine gas. Background technique [0002] As of the end of 2020, the total amount of gas pumped nationwide for the whole year is 19.8 billion cubic meters, with a utilization rate of 44.8%. More than 55% of the gas is directly discharged into the atmosphere. The reason for choosing direct discharge is because low-concentration gas is usually If the concentration is below 3%, internal combustion engines with higher efficiency cannot use it as a fuel, the development difficulty is high, and the cost investment is large, so it is almost impossible to use. For the utilization of low-concentration gas, there have been projects in the past where boilers were used for heat exchange to generate steam after exhaust air oxidation, and steam turbines were used to generate electricity. However, the thermal efficiency ...
