Description

Technical Field

[0001] The invention relates to the technical field of waste gas treatment, and in particular to a tobacco processing waste gas treatment system. Background Art

[0002] The tobacco processing waste gas treatment system is an equipment system used to treat waste gas generated during tobacco processing. During tobacco processing, a large amount of waste gas will be released due to processes such as tobacco baking, fermentation and drying, which may contain harmful substances and odors. The purpose of the tobacco processing waste gas treatment system is to effectively remove and treat harmful substances in the waste gas through a series of treatment equipment and processes to reduce the impact on the environment and human health.

[0003] The system usually includes key steps such as waste gas collection, purification and emission control. The waste gas collection part collects the generated waste gas from the source through a pipeline network to ensure that the waste gas can be effectively treated without leaking into the environment. The purification part uses various technologies such as adsorption, absorption, filtration and catalysis to remove or reduce harmful substances, particulate matter and odor in the waste gas to a level that meets emission standards. The emission control part ensures that the treated waste gas is discharged into the atmosphere safely and in compliance with regulations. The use of tobacco processing waste gas treatment system can effectively reduce pollution to the environment, improve the working environment and production conditions, and protect the health of employees and surrounding residents. This system is of great significance in the tobacco processing industry and plays a positive role in improving the sustainability and environmental protection of production.

[0004] At present, the structural design of the purification equipment used for tobacco processing waste gas treatment is too simple. During use, the existing purification equipment can only perform simple adsorption and filtration treatment on the waste gas generated during tobacco processing, and cannot catalyze and absorb the harmful waste gas generated by tobacco baking, fermentation and drying, and cannot detect the concentration of the harmful waste gas after the catalytic reaction. When the concentration test of the harmful waste gas after the catalytic reaction fails, the existing purification equipment cannot recycle and reprocess the waste gas whose concentration test does not meet the standard, which has certain limitations in use.

[0005] Based on this, the present invention designs a tobacco processing waste gas treatment system to solve the above-mentioned problems. Summary of the invention

[0006] The object of the present invention is to provide a tobacco processing waste gas treatment system to solve the above-mentioned problems.

[0007] To achieve the above-mentioned object, the present invention provides the following technical solution: a tobacco processing waste gas treatment system, comprising a first air purification mechanism and a second air purification mechanism, the second air purification mechanism is arranged on one side of the first air purification mechanism, a circulation mechanism is further installed between the first air purification mechanism and the second air purification mechanism, the circulation mechanism comprises a gas reflux component, the gas reflux component is connected between the top of the first air purification mechanism and the second air purification mechanism, and a gas guide component is further arranged between the bottom of the first air purification mechanism and the second air purification mechanism;

[0008] The first gas purification mechanism comprises an exhaust gas degradation tank, a first liquid storage tank is installed on the top of the exhaust gas degradation tank, and a liquid delivery component is also connected between the top of the first liquid storage tank and the bottom of the exhaust gas degradation tank;

[0009] The second air purification mechanism comprises an exhaust gas decomposition box, and a second liquid storage tank is installed at the bottom of one side of the exhaust gas decomposition box.

[0010] Based on the above technical features, the tobacco processing waste gas treatment equipment designed in this scheme can discharge harmful waste gas generated by tobacco baking, fermentation and drying into the interior of the airtight tank body by connecting one end of the first gas pipeline to the first air inlet when in use, and can spray the decomposition liquid stored in the liquid storage tank into the interior of the airtight tank body by the first spray plate installed on the bottom plate of the liquid storage tank body, so as to perform preliminary degradation treatment on the harmful waste gas inside the airtight tank body; in combination with the third gas pipeline, the first exhaust port and the second air inlet structure, the guide box seat and the blower can be connected between the waste gas degradation tank and the bottom of the waste gas decomposition box, and the harmful waste gas after degradation treatment inside the airtight tank body can be transported to the interior of the waste gas decomposition box;

[0011] When the harmful waste gas is transported to the interior of the waste gas decomposition box, the decomposition liquid can be sprayed on the surface of the two sets of neutralization filter plates installed in the middle of the inner cavity of the airtight box by running the second spray plate installed at the infusion pipe port of the infusion pump machine, so that the mesh surface of the neutralization filter plates can be soaked. Since the two sets of neutralization filter plates are acidic neutralization mesh plates and alkaline neutralization mesh plates, respectively, the two sets of neutralization filter plates after soaking can perform acid-base neutralization decomposition treatment on the harmful components in the harmful waste gas, so as to achieve the purpose of catalyzing and absorbing the harmful waste gas generated by tobacco baking, fermentation and drying;

[0012] This solution can detect the concentration of harmful waste gas after catalytic and absorption treatment by installing a concentration detector on the top of the inner cavity of the airtight box. Since the concentration detector is connected to the first electric control valve and the second electric control valve by electrical signals, when the concentration detector detects that the concentration of the harmful waste gas has reached the emission standard, the first electric control valve can be controlled to open and the second electric control valve can be controlled to close. At this time, the harmful waste gas after catalytic and absorption treatment inside the airtight box can be directly discharged to the outside. When the concentration detector detects that the concentration of the harmful waste gas does not reach the emission standard, the first electric control valve can be controlled to close and the second electric control valve can be controlled to open. At this time, the harmful waste gas inside the airtight box will be re-discharged into the waste gas degradation tank for the above-mentioned known recycling treatment until the concentration of the harmful waste gas reaches the emission standard.

Since the two groups of neutralization filter plates are acidic neutralization mesh plates and alkaline neutralization mesh plates, respectively, the two groups of neutralization filter plates after soaking can perform acid-base neutralization decomposition treatment on the harmful components in the harmful waste gas, thereby achieving the purpose of catalyzing and absorbing the harmful waste gas generated by tobacco baking, fermentation and drying.

Since the two sets of neutralization filter plates are acidic neutralization mesh plates and alkaline neutralization mesh plates respectively, the two sets of neutralization filter plates after being wetted can perform acid-base neutralization decomposition treatment on the harmful components in the harmful waste gas, so as to achieve the purpose of catalyzing and absorbing the harmful waste gas generated by tobacco baking, fermentation and drying;

[0030] 3. This scheme can detect the concentration of harmful waste gas after catalytic and absorption treatment by installing a concentration detector on the top of the inner cavity of the airtight box. Because the concentration detector is connected to the first electric control valve and the second electric control valve by electrical signals, when the concentration detector detects that the concentration of the harmful waste gas has reached the emission standard, the first electric control valve can be controlled to open and the second electric control valve can be controlled to close.
