Abstract
Description
Technical Field
[0001] This utility model belongs to the field of industrial waste gas treatment and relates to an integrated waste gas treatment device. Background Technology
[0002] With the continuous development of industrial production, industrial waste gas emissions have increased significantly, and the particulate matter and organic pollutants contained therein pose a serious threat to the environment and human health. Traditional waste gas treatment methods often struggle to effectively remove both particulate matter and organic gases, while increasingly stringent modern environmental protection requirements are forcing enterprises to seek more efficient and economical waste gas treatment solutions. Therefore, dry filtration and activated carbon adsorption technologies have been widely applied and have gradually become important components of waste gas treatment systems.
[0003] In integrated waste gas treatment equipment, dry filtration and activated carbon adsorption are often used in combination to achieve comprehensive treatment of multiple pollutants. The dry filter removes particulate matter from the waste gas beforehand, preventing it from entering the subsequent activated carbon adsorption unit, reducing clogging and wear of the activated carbon, thus extending its lifespan and improving overall treatment efficiency. The waste gas, after dry filtration, enters the activated carbon adsorption unit for further removal of organic compounds and odors, thereby effectively removing multiple pollutants from the waste gas. The combined application of dry filtration and activated carbon adsorption allows integrated waste gas treatment equipment to provide efficient and stable waste gas treatment capabilities within a limited space, making it particularly suitable for industries such as chemical, pharmaceutical, and coating.
[0004] However, the exhaust emissions of many production enterprises are uneven and variable. If the design exceeds the limit, it will cause greater costs in operation and maintenance. In addition, the large number of individual equipment will lead to problems such as complicated operation and large space occupation. If the average emission concentration is designed, there will be situations where the exhaust gas concentration is high and the emission exceeds the standard.
[0005] Therefore, it is necessary to optimize and integrate these two technologies to reduce the operating and maintenance costs of equipment, thus meeting the modern industrial demand for efficient, reliable, and economical environmental protection equipment. Utility Model Content
[0006] In view of the above-mentioned defects in the existing technology, the purpose of this utility model is to propose an integrated waste gas treatment device.
[0007] The objective of this utility model will be achieved through the following technical solution:
[0008] An integrated waste gas treatment device includes a dry filtration mechanism comprising two processing units, each containing an inclined filter media layer. The filter media of one processing unit is positioned at the front end. The dry filtration mechanism consists of two dry filtration units. Each dry filtration unit uses inclined dry filter media, with the media arranged one in front of the other. An activated carbon adsorption mechanism, consisting of two activated carbon adsorption units, is located at the rear end of the dry filtration mechanism, parallel to the dry filtration units. Each activated carbon adsorption unit comprises an inclined activated carbon adsorption device and a vertical activated carbon adsorption device, symmetrically arranged within the two activated carbon adsorption units. Electric pneumatic valves are located between the two dry filtration units and between the two activated carbon adsorption units. Pipeline valves are located on the inlet and outlet pipes of each unit.
[0009] Preferably, the dry filtration mechanism divides the two dry filtration units into upper and lower regions, and the activated carbon filtration mechanism divides the two activated carbon adsorption units into upper and lower regions, and keeps them parallel to the dry filtration units.
[0010] Preferably, the filter media device in the dry filtration unit is inclined, with an angle of 40° to 60°;
[0011] Preferably, the two dry filter units are connected by an electric steel door with a rubber ring, and the electric steel door is located between the two sets of dry filter media.
[0012] Preferably, the activated carbon in the activated carbon filter unit is arranged in two sets of axisymmetric inclined arrangement with an angle of 40°~60°, and the empty space in one set of inclined activated carbon is arranged as a vertical activated carbon filter with a width of 0.2~0.4 m.
[0013] Preferably, the two activated carbon filter units are connected by an electric steel door with a rubber ring, and the electric steel door is located at the end of the activated carbon adsorption material in the unit.
[0014] Preferably, two dry filtration units and two activated carbon adsorption units are connected in parallel via a pipeline, and the pipeline is equipped with an electric air valve.

[0016] Preferably, the activated carbon adsorption packing bin is made of fine-mesh stainless steel, and the bin can be filled with either honeycomb activated carbon or granular activated carbon according to actual needs.
[0017] The outstanding advantages of this invention are as follows: The internal dry filtration unit adopts a sloping structure, increasing the effective filtration area and improving dry filtration efficiency. Simultaneously, the activated carbon adsorption box employs a thin-walled sloping activated carbon filling design, increasing the effective filtration area without sacrificing fan efficiency. Furthermore, the addition of a vertical activated carbon filling design between the two lower sections enhances the adsorption effect of the entire activated carbon adsorption unit, enabling the device to handle higher concentrations of waste gas. In addition, this design is suitable for treating a wider variety of waste gases. Depending on the specific concentration of the waste gas, the series and parallel connections of the dry filters and activated carbon filters can be adjusted by controlling the opening and closing of the electric air valve, achieving excellent waste gas treatment results with minimal resource waste and economic efficiency.
[0018] In summary, this utility model has excellent performance, ingenious structure, and effectively alleviates the problems of uneven and unstable exhaust gas, which sometimes wastes resources and sometimes has poor treatment effect. It has high application and promotion value.

[0022] This utility model discloses an integrated waste gas treatment device.
[0023] like Figure 1As shown, an integrated waste gas treatment device is fixedly installed at the front end of a fan. The internal components of the integrated device, from left to right, are a dry filtration mechanism and an activated carbon adsorption mechanism. The device includes an outer casing 1 and connecting pipes between the various units. The pipes include an air inlet pipe 41, a connecting pipe between the dry filtration and activated carbon filtration, and an activated carbon exhaust pipe. Each pipe is equipped with an electric valve. The dry filtration mechanism consists of two filtration units, upper and lower, connected in the middle by an electric valve 61 with a rubber-coated internal dry filtration unit. The activated carbon adsorption mechanism also consists of two filtration units, upper and lower, connected in the middle by an electric valve 62 with a rubber-coated internal activated carbon adsorption unit.
[0024] The thickness of the filter media in the two dry filter units can be adjusted according to the actual situation. The upper dry filter media 221 is located on the left side at an angle of 40°~60°, and the lower dry filter media 211 is located on the right side at an angle of 40°~60°. The electric valve 61 connecting the dry filter is located in the middle.
[0025] The dry filter media loading rack is made of stainless steel and features an inclined push-pull design for easy media replacement.
[0026] Both activated carbon filter units are equipped with a lower inclined activated carbon packing 311 and an upper inclined activated carbon packing 321 arranged in a symmetrical manner. In the middle of each set of symmetrical activated carbon packing, a lower vertical activated carbon packing 312 and an upper vertical activated carbon packing 322 are arranged, with a width of 0.2~0.4 m. The two units are connected at the far right by an electric valve 62 connected inside the activated carbon adsorption system. The number of sets of symmetrical and vertical activated carbon packing can be designed according to the actual situation.
[0027] The activated carbon packing racks are all made of stainless steel and have a push-pull design for easy packing replacement.
[0028] The activated carbon adsorption unit has an exhaust pipe connected in parallel with the upper activated carbon adsorption exhaust pipe 432 and the lower activated carbon adsorption exhaust pipe 431 at the upper dry-activated carbon upper layer connecting pipe 422.
[0029] The working process of this utility model is briefly described below: First, this utility model is divided into five modes, which can be selected in real time according to different components when the main components of the waste gas have large intermittent differences. The first mode is that the electric valve 61 connected inside the dry filter and the electric valve 62 connected inside the activated carbon adsorption are closed, and the electric valve 533 of the activated carbon mechanism in series is closed. The whole device is in parallel, which is mainly for the case of large waste gas generation. The waste gas enters the two dry filter units in parallel through the equipment inlet pipe 41, and then enters the two activated carbon filter units through the parallel pipe. After treatment, the waste gas is discharged in compliance with the standards through the parallel pipe.
[0030] The second mode involves closing the lower dry filter inlet electric valve 511, the dry-activated carbon upper layer connecting electric valve 522, the lower activated carbon adsorption outlet electric valve 531, and the upper activated carbon adsorption outlet electric valve 532. The dry filter internal connecting electric valve 61 and the activated carbon adsorption internal connecting electric valve 62 are open. The entire device consists of two units connected in series, primarily targeting situations with high pollutant concentrations in the exhaust gas. The exhaust gas enters the dry filter mechanism through the upper dry filter inlet electric valve 512, then passes through the dry filter internal connecting electric valve 61 for further filtration, and then enters the activated carbon adsorption unit through the dry-activated carbon lower layer connecting pipe 421. Subsequently, it enters the activated carbon adsorption unit for further adsorption through the activated carbon adsorption internal connecting electric valve 62, and finally, it is discharged through the dry-activated carbon upper layer connecting pipe 422-activated carbon mechanism series outlet pipe 433 to meet emission standards. In this mode, the fan airflow needs to be reduced to ensure sufficient air pressure.
[0031] The third mode involves opening the lower dry filter inlet electric valve 511, the dry-activated carbon upper layer connecting electric valve 522, the upper activated carbon adsorption outlet electric valve 532, and the dry filter internal connecting electric valve 61, while all other electric valves are closed. This mode is mainly for situations where the exhaust gas has low humidity and few particulate matter. The exhaust gas can enter the device through the lower dry filter inlet electric valve 511, bypass the dry filter directly through the dry filter internal connecting electric valve 61, and then enter the activated carbon adsorption unit for adsorption treatment through the dry-activated carbon upper layer connecting electric valve 522. Finally, it can be discharged directly to meet the standards through the upper activated carbon adsorption outlet electric valve 532.
[0032] The fourth mode involves opening the upper dry filter inlet electric valve 512, the dry filter internal connection electric valve 61, the dry-activated carbon lower layer connection electric valve 521, and the lower layer activated carbon adsorption outlet electric valve 531, while all other electric valves are closed. This mode is mainly for situations where the exhaust gas has high humidity and a large amount of particulate matter, but the concentration of other pollutants is low. The exhaust gas can enter the dry filter device through the upper dry filter inlet electric valve 512 and be further filtered by the activated carbon adsorption internal connection electric valve 62. Then, it enters the activated carbon adsorption unit for adsorption through the dry-activated carbon lower layer connection electric valve 521, and finally passes through the lower layer activated carbon adsorption outlet electric valve 531 to directly meet the emission standards.
[0033] The fifth mode involves opening the lower dry filter inlet electric valve 511, the dry filter internal connection electric valve 61, the dry-activated carbon upper connection electric valve 522, and the activated carbon mechanism series outlet electric valve 533, while all other electric valves are closed. This mode is mainly for exhaust gases that can directly meet emission standards. To save costs, emissions can be directly achieved by using the lower dry filter inlet electric valve 511, the dry filter internal connection electric valve 61, the dry-activated carbon upper connection electric valve 522, and the activated carbon mechanism series outlet electric valve 533.
[0034] This utility model device is highly adaptable, designed with five modes, allowing for flexible selection of different filtration and adsorption paths based on variations in the main components and concentrations of the waste gas. This makes the device perform better when dealing with waste gas components that exhibit significant intermittent variations, improving the accuracy and effectiveness of treatment. It is energy-efficient and highly effective; by selecting different modes, the device can optimize treatment for specific pollutant concentrations and waste gas volumes. For example, when the waste gas concentration is low or can directly meet emission standards, a simplified treatment mode can be selected, thereby saving energy and costs. It offers flexible combinations, enabling both parallel and series operation. When the waste gas volume is large, parallel operation can increase the treatment capacity; when the pollutant concentration is high, series operation can enhance the treatment effect. This flexibility improves the utilization rate and adaptability of the treatment equipment. Precise control is achieved through multiple electric valves and electric steel gates, allowing for precise control of the waste gas flow and treatment method, improving system stability and treatment accuracy. Optimized treatment effects are achieved through the configuration of dry filtration units and activated carbon filtration units, effectively treating different types of pollutants, improving the purification effect of waste gas, and ensuring that emissions meet standards. Overall, this utility model has the advantages of high flexibility, energy efficiency and precise treatment, and is very suitable for the treatment of industrial waste gas with complex composition and strict emission requirements.
