Description

Technical Field

[0001] The utility model relates to a peculiar smell air treatment system, belonging to the field of chemical waste gas treatment. Background Art

[0002] During operation, sewage treatment equipment will produce a large amount of toxic and harmful gases, which will harm the air quality and human health, cause serious pollution to water bodies, soil and ecosystems, and destroy the ecological balance.

[0003] At present, the methods for treating industrial waste gas include catalytic oxidation, chemical reaction, activated carbon adsorption, ultraviolet light and soil deodorization. These methods not only consume a lot of energy and material consumption in the process of treating industrial waste gas, but also inevitably produce new pollutants, which require further treatment. Summary of the Invention

[0004] According to the background problem, the problem to be solved by the present invention is:

[0005] How to effectively treat toxic and harmful gases in sewage treatment while maintaining low energy and material consumption.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A peculiar smell air treatment system comprises a peculiar smell air generating and collecting device, a fan, a conveying pipeline and a furnace-front air duct; the peculiar smell air generating and collecting device is connected to the conveying pipeline through the fan, the conveying pipeline is connected to the furnace-front air duct, and the conveying pipeline is provided with a combustible analyzer, an emergency vent line, a combustible interlock valve and a conveying pipeline control valve; the combustible analyzer is arranged at the fan outlet, the emergency vent line is arranged in front of the combustible interlock valve, the emergency vent line is provided with an emergency vent valve, the combustible analyzer is electrically connected to the fan, the emergency vent valve and the combustible interlock valve, the furnace-front air duct is provided with a pressure gauge and a pressure interlock valve, the pressure gauge is electrically connected to the pressure interlock valve, the furnace-front air duct is connected to the boiler, the peculiar smell air enters the boiler and the exhaust gas in the peculiar smell air is treated in the boiler flue gas treatment section.

[0008] Preferably, the odorous air generating and collecting device is a structure that generates waste gas with a sealed cover.

[0009] Preferably, the combustible analyzer analyzes that the combustible concentration reaches an interlock value, that is, the combustible interlock valve and the blower are interlocked and closed, and the emergency vent valve is opened.

[0010] Preferably, the emergency vent line is connected to a temporary odor collection tank. When the combustibles in the odorous air exceed the standard, the combustible interlock valve closes, and the emergency vent line discharges the odorous air into the temporary odorous air collection tank, ensuring that the waste gas will not be discharged into the air and pollute the environment.

[0011] Odor-inducing air is air mixed with volatilized or waste gas generated during sewage treatment. The utility model uses odor-inducing air to replace part of the air in the boiler inlet air, which does not affect the boiler combustion and can use the boiler flue gas treatment section to treat the waste gas in the odor-inducing air, eliminating a set of waste gas treatment equipment and greatly reducing energy consumption and costs.

[0012] The combustible content of the odorous air entering the boiler must be controlled, otherwise it will cause explosion and lead to safety accidents. The utility model is equipped with a combustible interlock, which measures the combustible content in the odorous air through a combustible analyzer. When the combustible content reaches the set value, the interlock stops the air flow to ensure the safe operation of the boiler.

[0013] The beneficial effects of the utility model are:

[0014] This new system eliminates the need for separate odor-removing air treatment facilities, reducing energy consumption and processing losses. The waste gas treatment process is simple and stable, avoiding environmental pollution caused by unstable waste gas treatment facilities. Toxic and hazardous waste gases are completely treated, eliminating secondary pollution. BRIEF DESCRIPTION OF THE DRAWINGS
