Boiler combustion generally uses coal as fuel. The exhaust gas generated by coal combustion contains carbon monoxide, nitrogen monoxide, sulfur dioxide, solid dust and other components, and the high-temperature exhaust gas will further generate harmful substances such as dioxin when it contacts the air, and the exhaust gas is directly discharged Air will cause atmospheric pollution. During the treatment of high-temperature waste gas, the heat energy carried by high-temperature waste gas is often not treated, and it is still discharged in the form of high-temperature air, which is more likely to cause thermal pollution to the environment and damage the ecological environment.

[0003] After searching, the Chinese patent application number is CN108079709A, which discloses a high-temperature exhaust gas treatment device, which includes a vertically arranged first pipe body, a horizontally arranged second pipe body, a vertically arranged third pipe body, The fourth pipe body and the fifth pipe body, the upper end of the first pipe body communicates with the upper end of the third pipe body through the second pipe body, one end of the fourth pipe body communicates with the first pipe body, The other end is inclined downward toward the third pipe body; one end of the fifth pipe body communicates with the third pipe body, and the other end is inclined downward toward the first pipe body; The lower end of the pipe body communicates with the lower end of the fifth pipe body, a plurality of nozzles are respectively arranged in the first pipe body, the second pipe body and the third pipe body, and the side wall of the first pipe body is provided with a One end of the air intake pipe communicates with the first pipe body, the other end is provided with an air inlet, and the side wall of the third pipe body is horizontally provided with an air outlet pipe; the purification pipe is vertically arranged At the end of the gas outlet pipeline, one end of the purification pipeline communicates with the top of the end of the gas outlet pipeline, and the other end is provided with a gas outlet and communicates with the outside atmosphere. A purification unit for purifying the exhaust gas is arranged in the purification pipeline. It can recover energy from the waste heat of industrial waste gas, which is energy-saving and environmentally friendly, but it cannot effectively filter industrial waste gas and discharge it without pollution, and when water resources are recycled, it cannot effectively filter water resources before using them

[0004] At present, the existing waste gas treatment devices generally pass the waste gas into the scrubber, and then cool it down and wash it with water, and then discharge it into the atmosphere. However, they cannot effectively degrade and separate the harmful gases and solid impurities contained in the waste gas. The rate is not high. When recycling water resources, the harmful substances contained in the water resources cannot be filtered before use. As a result, when the water resources are sprayed on the waste gas, not only cannot effectively degrade the harmful substances contained in the waste gas, but it is more likely to Increase the content of harmful substances in the exhaust gas, resulting in low efficiency of water resource recycling. It is impossible to quickly filter the fixed impurities, small impurities and tiny impurities contained in the exhaust gas layer by layer. The existing exhaust gas treatment device is filtering the exhaust gas. Only water resources are used to spray the waste gas. This method can cool down the high-temperature waste gas and adsorb the fixed impurities contained in the waste gas. As a result, the temperature of the water resource itself rises gradually, thereby reducing the recycling efficiency of water resources. On the other hand, water spray can adsorb large fixed impurities, but it is difficult to adsorb fine and tiny dust, resulting in exhaust gas passing through When the filter layer is used, the dust blocks the gas filter layer, causing the overall filtration speed of the exhaust gas to slow down. In severe cases, the internal pressure of the exhaust gas treatment device will increase, resulting in damage to the filter device, which greatly affects the filtration and emission of exhaust gas, which cannot meet people's current requirements for exhaust gas. The need for pollution-free emissions
