Description

Technical Field

[0001] This utility model belongs to the field of waste gas treatment, specifically relating to an organic waste gas treatment device. Background Technology

[0002] Organic waste gas treatment devices are generally used to treat organic gases generated in industrial processes, such as solvents and volatile organic compounds. These waste gases are highly polluting and therefore require effective technical means to treat them. Common treatment methods include adsorption, catalytic combustion, condensation, and plasma treatment.

[0003] Most existing organic waste gas treatment equipment filters organic waste in waste gas through adsorption. However, after prolonged use, organic pollutants and particles in the waste gas will adsorb onto the surface of the adsorption filter structure, thus clogging the filter structure and affecting its filtration effect. Furthermore, the filter structure in traditional adsorption waste gas treatment equipment is mostly fixed, which is time-consuming and laborious when cleaning or disassembling it, thus significantly affecting the use effect and efficiency of the waste gas treatment equipment.

[0004] Therefore, to address the problem of the difficulty in cleaning and maintaining the internal filter structure of existing organic waste gas treatment devices, an organic waste gas treatment device is developed. By adding a pulse lifting structure and a pollutant collection structure to the organic waste gas treatment equipment, the service life of the filter structure inside the waste gas equipment can be effectively extended, and its maintenance frequency and cost can be reduced.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figures 1-6 This utility model provides an embodiment of an organic waste gas treatment device, including a first filter tank 2 and a second filter tank 3, as well as a collection cabinet 6, a collection box 11, a pulse pipe 13, and a pulse generator 15. The first filter tank 2 and the second filter tank 3 are connected to each other through a tank body connecting flange 7. Several sets of equidistantly distributed primary activated carbon filter elements 16 and secondary activated carbon filter elements 17 are respectively installed on the inner walls of the first filter tank 2 and the second filter tank 3. Three sets of equidistantly distributed pulse pipes 13 are installed on the inner walls of the primary activated carbon filter elements 16 and the secondary activated carbon filter elements 17. The pulse pipes 13 are connected to three sets of pulse generators 15 through several sets of equidistantly distributed connecting pipes 14. A collection box 11 is installed on the lower outer wall of the first filter tank 2 and the second filter tank 3. A matching collection cabinet 6 is provided in the collection box 11. A handle 10 is fixedly connected to the front end of the collection cabinet 6.

[0025] A pulsed airflow is generated by a pulse generator 15 using high-pressure gas and delivered to the pulse pipe 13 along several sets of connecting pipes 14. This airflow impacts the surfaces of the primary activated carbon filter 16 and the secondary activated carbon filter 17 from the inside, thereby helping to remove particulate matter and contaminants adhering to the surfaces of the primary and secondary activated carbon filter elements 16 and 17. This extends the service life of the primary and secondary activated carbon filter elements 16 and 17 and reduces maintenance frequency and costs. The particulate matter and contaminants after pulse cleaning fall into the collection box 11 along the inner walls of the first filter canister 2 and the second filter canister 3. Users can simply pull the handle 10 to clean the particulate matter and contaminants in the collection box 11, thus improving the convenience of maintaining and cleaning the primary and secondary activated carbon filter elements 16 and 17.

[0026] Please see Figures 3-4 In this embodiment, an air inlet pipe 9 is installed at the left end of the first filter tank 2, and a fan connecting flange 12 is fixedly connected to the right end of the second filter tank 3. In use, the air inlet pipe 9 allows the user to easily transport organic waste gas into the device for filtration and purification. A centrifugal fan 4 is fixedly connected to the right end of the fan connecting flange 12, and an exhaust pipe 5 is fixedly connected to the upper end of the centrifugal fan 4. In use, the centrifugal fan 4 can assist the filtered and purified organic waste gas to be discharged upward from the exhaust pipe 5.

[0027] Please see Figure 6 In this embodiment, the outer walls of the first filter tank 2 and the second filter tank 3 are equipped with protective shells 1. The upper end of the protective shell 1 is provided with three sets of equally spaced mounting slots 18. In use, the protective shell 1 can protect several sets of connecting pipes 14 to improve their service life. The front and rear ends of the protective shell 1 are provided with several sets of equally spaced dustproof slots 19. The pulse generator 15 is fixed in the mounting slots 18. In use, the dustproof slots 19 can prevent external dust from adsorbing on the outer wall of the connecting pipes 14, affecting their normal use and service life.

[0028] Please see Figures 3-6 In this embodiment, the upper outer walls of the first filter tank 2 and the second filter tank 3 are provided with several sets of equidistantly distributed through holes 8. The outer wall of the connecting pipe 14 is seamlessly connected to the inner wall of the through holes 8. In use, the seamless connection of the connecting pipe 14 and the through holes 8 can prevent the organic waste gas in the first filter tank 2 and the second filter tank 3 from overflowing outward along the through holes 8. The first filter tank 2 is located on the left side of the second filter tank 3. Several sets of connecting pipes 14 are located on the inner wall of the protective shell 1. The first filter tank 2 and the second filter tank 3 are connected to their corresponding collection boxes 11. In use, the interconnected collection boxes 11 and the first filter tank 2 and the second filter tank 3 can allow the cleaned particulate matter and pollutants to fall downward from the inner wall of the first filter tank 2 and the second filter tank 3 into the collection cabinet 6 inside the collection box 11.

[0029] In use, the organic waste gas is first transported through the pipeline along the inner wall of the air inlet pipe 9 to the first filter tank 2, and the centrifugal fan 4 draws the organic waste gas from left to right. It then undergoes two-stage coarse filtration and adsorption through several sets of primary activated carbon filter elements 16 and secondary activated carbon filter elements 17 in the first filter tank 2 and the second filter tank 3, so as to adsorb particulate matter and pollutants in the organic waste gas onto the primary activated carbon filter elements 16 and the secondary activated carbon filter elements 17.

[0030] Next, the centrifugal fan 4 blows the filtered and purified organic waste gas upwards and discharges it outwards along the inner wall of the exhaust pipe 5.

[0031] When it is necessary to clean the primary activated carbon filter element 16 and the secondary activated carbon filter element 17, the pulse generator 15 is activated, which generates a high-pressure pulse airflow that is transported to the pulse pipe 13 along several sets of connecting pipes 14 to impact the particulate matter and contaminants on the surface of the primary activated carbon filter element 16 and the secondary activated carbon filter element 17, so that the particulate matter and contaminants on the surface of the primary activated carbon filter element 16 and the secondary activated carbon filter element 17 fall down along the inner wall of the first filter tank 2 and the second filter tank 3 into the collection cabinet 6 in the collection box 11;

[0032] Then, pull handle 10 to remove collection cabinet 6 from collection box 11, and clean the particulate matter and pollutants inside collection cabinet 6.

[0033] Through the above steps, the pulse generator 15 uses high-pressure gas to generate a pulse airflow, which is then transported to the pulse pipe 13 along several sets of connecting pipes 14. This pulse airflow impacts the surfaces of the primary activated carbon filter element 16 and the secondary activated carbon filter element 17 from within, thereby helping to remove particulate matter and contaminants adhering to their surfaces. This extends the service life of the primary and secondary activated carbon filter elements 16 and 17, and reduces maintenance frequency and costs. The particulate matter and contaminants removed by the pulse cleaning fall into the collection box 11 along the inner walls of the first filter tank 2 and the second filter tank 3. Users can simply pull the handle 10 to clean the particulate matter and contaminants in the collection box 11, thus improving the convenience of maintaining and cleaning the primary and secondary activated carbon filter elements 16 and 17. This solves the problem of the difficulty in cleaning and maintaining the internal filtration structure of existing organic waste gas treatment devices.

[0034] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
