Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of waste gas treatment devices, specifically a waste gas treatment device for environmental engineering. Background Technology
[0002] In environmental engineering, waste gas mainly originates from industrial production (such as chemical, metallurgical, and power generation), vehicle exhaust, fuel combustion (coal and gas), waste disposal, and agricultural activities. Waste gas types include particulate matter (PM2.5 / PM10), sulfur oxides (SOx), nitrogen oxides (NOx), carbon oxides (CO, CO2), volatile organic compounds (VOCs), and odorous gases. Their harmful effects are severe, leading to air pollution (smog, acid rain, ozone layer depletion), exacerbating the greenhouse effect, and directly damaging human respiratory, cardiovascular, and nervous system health. Therefore, waste gas purification devices must be used for treatment. Common methods include physical methods (such as dust collectors and adsorption towers), chemical methods (such as absorption towers, catalytic combustion, and thermal incineration), and biological methods (such as biofilters and biotrickling filters). These technologies and devices intercept, adsorb, transform, or degrade pollutants, ultimately achieving emission standards. They are a key link in improving air quality, and in practical applications, multiple technologies are often combined to achieve the best purification effect.
[0003] Most existing waste gas treatment devices are combinations of multiple purification devices, which have limited functions and are difficult to maintain and clean, making them unsuitable for use. Therefore, it is necessary to propose a waste gas purification device with more comprehensive purification functions and stronger combination capabilities. Utility Model Content

[0013] Compared with the prior art, this utility model provides a waste gas treatment device for environmental engineering, which has the following beneficial effects:
[0014] 1. The multi-stage dust removal mechanism is used for multiple purification of exhaust gas. This mechanism separates large dust particles by cyclone separation after the air is dried, and separates oil and gas that may be contained in the air with the help of activated carbon. At the same time, the filter cloth can separate dust and extend its service life when dry. The rotary joint can connect the filter box after the rotating cover is installed and limit the filter cloth and activated carbon, which is convenient for quick replacement when opening.

[0015] 2. The separation and purification mechanism is used to purify the residual harmful gases in the exhaust gas. This mechanism purifies the harmful substances in the exhaust gas by spraying and adsorbing them, followed by drying, pressurizing, and combustion. This allows the device to meet the requirements of exhaust gases with various impurities, thereby improving the adaptability of the device. Attached Figure Description

[0029] Furthermore, a tubular structure is provided on the lower side of the filter box 507 and is fixedly connected to the inner wall of the vortex vane 506.
[0030] Furthermore, a lime block is fixedly connected inside the moisture-absorbing box 502, and activated carbon is fixedly connected to the upper surface of the activated carbon rack 508.
[0031] Example 2:
[0032] This device is designed for purifying more complex gases and enhances the adaptability of the purification system. Please refer to [link / reference needed]. Figure 1-5 Furthermore, in conjunction with Embodiment 1, it is further obtained that the separation and purification mechanism 6 includes multiple sponges 601, all of which are fixedly connected inside the spray tower 2.

[0034] Furthermore, the spray tower 2 is equipped with a conventional water pumping and filtration circulation structure.
[0035] In actual operation, when this device is used, the user starts the device and uses a fan to collect the exhaust gas. The user opens the sealing cover 503, puts lime blocks into the moisture absorption box 502, and then seals the sealing cover 503. Subsequently, the user sends the collected exhaust gas into the gas collection pipe 501. After passing through the moisture absorption box 502, the exhaust gas passes through the inlet pipe 505 and enters the separator 1. At this time, the airflow is driven by the vortex vane 506 and, with high flow velocity, generates an airflow vortex inside the separator 1. The airflow vortex throws large dust particles into the separator 1 by centrifugal force. Then, the dust enters the collection box 7 by centrifugal force, while the exhaust gas enters the filter box 507 through the lower pipe. At this time, the airflow comes into contact with the activated carbon inside the filter box 507 and separates the oily impurities. When the activated carbon needs to be replaced, the user can rotate the rotating cover 511. The rotating cover 511 drives the clamping ring 512 to disengage from the filter cloth 510. At this time, the filter cloth... When filter cloth 510 is released from its limit position, the user can remove and clean it. Simultaneously, the activated carbon can be replaced and refilled before screwing on the rotating cover 511. The airflow rises and passes through filter cloth 510 into the spray tower 2. The user can supply water pressure to the sprayer 602 to generate water mist. The water mist wets the sponge 601, and the exhaust gas passes through the damp sponge 601 for further filtration of hydrophilic harmful exhaust gases and impurities. Subsequently, the exhaust gas passes through the drying chamber 4 and is dried before entering the combustion chamber 3. When the hydraulic control telescopic component 605 is working, it drives the piston disc 606 to generate pressure inside the combustion chamber 3. This pressure briefly closes the one-way pipe 604. As the pressure inside the combustion chamber 3 increases, when the hydraulic control telescopic component 605 approaches its maximum stroke, ignition can be performed inside the combustion chamber 3, allowing any combustible gases carried inside the exhaust gas to be pressurized and burned. After the exhaust gas is burned or after the hydraulic control telescopic component 605 reaches its maximum stroke, the pressure relief valve 607 opens, releasing the purified gas.
