Description

Technical Field

[0001] The utility model relates to the technical field of atmospheric desulfurization, in particular to an atmospheric desulfurization device for environmental protection engineering. Background Art

[0002] Environmental protection projects refer to projects specifically designed for environmental protection. Based on a set of envisioned goals, they use relevant scientific knowledge and technical means to deal with environmental pollution problems through the organized activities of a group of people. The content of environmental protection projects mainly includes air pollution prevention and control projects, water pollution prevention and control projects, solid waste treatment and utilization projects, noise control projects, etc.

[0003] Desulfurization refers to the process of removing sulfur from fuel before combustion and before flue gas emission. It is one of the important technical measures to prevent and control air pollution. At present, there are generally three desulfurization methods: desulfurization before combustion, desulfurization during combustion and desulfurization after combustion. With the development of industry and the improvement of people's living standards, the demand for energy is also increasing. SO2 in coal-fired flue gas has become the main cause of air pollution. Reducing SO2 pollution has become a top priority for today's atmospheric environmental governance.

[0004] When applying for the present invention, the applicant found through searching that a Chinese patent disclosed an "atmospheric desulfurization device for environmental protection engineering", and its application number is "202022706479.4". The patent mainly includes a desulfurization box, a water tank is installed on one side of the desulfurization box, a gas pipeline is installed in the water tank, a through hole is provided on one side of the desulfurization box, a filter is installed at one end of the gas pipeline passing through the through hole, an atomization rack is installed in the desulfurization box, a liquid guide tube is installed at the water-drawing end of the atomization rack, and a Perforation, a chemical water pump is installed on one side of the desulfurization box, a liquid extraction pipe is inserted on one side of the desulfurization box, and the other end of the liquid extraction pipe is installed on the chemical water pump. The solenoid valve is opened through the control panel, and the exhaust gas in the exhaust pipe enters the gas transmission pipe, and then is discharged into the desulfurization box through the filter holes on the filter. The chemical water pump pumps the desulfurization liquid into the atomization rack through the liquid guide pipe and then sprays it out, so that the atomized desulfurization liquid and the exhaust gas are fully mixed. The filter plate filters the gas and then discharges it through the outlet pipe, which solves the problem of poor desulfurization effect in the prior art.

[0005] Although the above patent realizes the desulfurization of waste gas, during the desulfurization process, the waste gas passes through the gas pipeline and directly enters the desulfurization box for desulfurization. This desulfurization method only desulfurizes the discharged waste gas once, which easily leads to the phenomenon that the waste gas is discharged after incomplete desulfurization. The desulfurization effect of the waste gas is poor. Therefore, it is necessary to design an atmospheric desulfurization device for environmental protection projects. Utility Model Content

Since multiple partitions divide the interior of the box into multiple desulfurization chambers, and the spray end of the spray mechanism corresponds to the desulfurization chamber, after the exhaust gas enters the interior of the box, it passes through multiple desulfurization chambers for desulfurization treatment, thereby improving the desulfurization effect of the exhaust gas and facilitating better desulfurization treatment of the exhaust gas in environmental protection projects.

[0027] Specifically, a certain amount of desulfurization liquid is added to the inside of the box body 1 so that the uppermost end of the desulfurization liquid does not exceed the lower end of the air inlet pipe 14. Then the exhaust gas enters the inside of the air guide pipe 18 through the air inlet pipe 14, and then enters the desulfurization liquid through the air guide pipe 18 for preliminary desulfurization.
