There are many types of industrial boilers, including fire tube, water tube, heat medium, cross-flow and other forms. Each type has its specific uses and characteristics. However, despite playing an important role in industrial development, the exhaust gas emissions of such boilers are an environmental challenge that cannot be ignored. Generally speaking, the exhaust gas temperature of such boilers mostly exceeds 200 degrees Celsius. If this high temperature is discharged into the atmosphere, it will not only cause air pollution, but also aggravate global warming. This is a very serious environmental problem.

[0024] Furthermore, a groove 2 is opened on the side of the first purification chamber 3 away from the air inlet pipe 1, and one end of the air supply pipe 10 is fixedly connected in the groove 2. The first purification chamber 3 and the second purification chamber 11 are connected through the air supply pipe 10, and the exhaust gas initially purified in the first purification chamber 3 is introduced into the second purification chamber 11 through the air supply pipe 10.

[0025] Furthermore, a groove three is opened on the side of the second purification chamber 11 away from the air outlet pipe 15, and one end of the air supply pipe 10 is fixedly connected in the groove three. The first purification chamber 3 and the second purification chamber 11 are connected through the air supply pipe 10, and the exhaust gas purified for the first time is introduced into the second purification chamber 11 for secondary purification.

[0026] Furthermore, a groove four is opened on the side of the treatment liquid storage chamber 6 away from the air inlet pipe 1, and one end of the circulating water pipe 8 is fixedly connected to the groove four. The treatment liquid storage chamber 6 and the cooling chamber 9 are connected through the circulating water pipe 8, and the treatment liquid that is heated due to the exhaust gas in the first purification chamber 3 is introduced into the cooling chamber 9 for cooling.

[0027] Furthermore, a groove five is opened on the side of the cooling chamber 9 away from the air inlet pipe 1, and one end of the circulating water pipe 8 is fixedly connected to the groove five. The treatment liquid storage chamber 6 and the cooling chamber 9 are connected through the circulating water pipe 8, and the cooled treatment liquid is sprayed out through the nozzle to circulate and purify the exhaust gas.

[0028] Furthermore, the width of the adsorption filter 5 is longer than the width of the first purification chamber 3, so that the adsorption filter 5 can be easily drawn out for cleaning.

[0029] Furthermore, the adsorption filter 5 is provided with a hand-held portion, and the surface of the hand-held portion of the adsorption filter 5 is covered with a sealing layer.

[0030] Working principle: When recovering boiler exhaust gas, first connect the air inlet pipe 1 of the device to the air outlet of the boiler, introduce the exhaust gas into the first purification chamber 3 through the air pump 2, open the spray head 4, spray the mist treatment liquid, mix it with the exhaust gas, take away the toxic substances and dust in the exhaust gas, and reduce the heat of the exhaust gas. The treatment liquid enters the treatment liquid storage chamber 6, and is introduced into the cooling chamber 9 through the water pump 7 and the circulating water pipe 8 for cooling. The cooled cooling chamber 9 is sprayed out from the spray head 4, and the waste is circulated to purify and cool down. The adsorption filter 5 arranged in the first purification chamber 3 can filter out solid particles and other substances in the treatment liquid after purifying the exhaust gas, thereby increasing the number of times the treatment liquid can be recycled. The initially purified exhaust gas is introduced into the second purification chamber 11 through the gas pipe 10. The fine filter 12 arranged in the second purification chamber 11 filters the remaining fine particles in the exhaust gas, and the activated carbon net 13 adsorbs the remaining toxic substances in the exhaust gas. The sponge 14 absorbs the water vapor in the exhaust gas, and finally discharges it through the exhaust pipe 15 to complete the recovery and treatment of the exhaust gas. Through the carefully designed first purification chamber 3 and the second purification chamber 11, we can effectively treat the exhaust gas to achieve a higher standard of purification effect. This double filtration system not only improves the efficiency and quality, but also ensures that the pollutants are completely removed during the entire purification process, thereby making an important contribution to environmental protection. Through the spray head 4, assisted by an efficient water pump 7 and a precise circulating water pipe 8, the exhaust gas purification system can ensure that the treatment liquid is fully utilized when treating the exhaust gas, which not only improves the efficiency of resource utilization, but also ensures the cleanliness of the environment and the sustainability of the ecology. During the entire purification process, every drop of treated liquid is properly recovered and reused in subsequent purification steps, thereby realizing a closed-loop management environmental protection process. This sophisticated operation method ensures cost optimization.
