Description

Technical Field

[0001] The present invention relates to the technical field of waste gas treatment, and specifically relates to a waste gas treatment device for environmental protection material processing. Background Technique

[0002] The "environmental protection" of environmental protection materials (such as degradable plastics, bio-based resins, recycled fibers) is mainly reflected in the life cycle of end products (such as recyclability, low toxicity), but high-pollution waste gas may still be generated in the production and processing links. In the processing of environmental protection materials, the design of the waste gas introduction system directly determines the treatment efficiency and compliance.

[0003] The patent with the publication number CN216223417U discloses a waste gas treatment device for environmental protection material processing, including a waste gas treatment device housing, a filtration chamber, a heating chamber, and a cooling chamber. An air inlet pipe is fixedly installed on the left side of the waste gas treatment device housing. An air inlet pipe valve is fixedly installed on the top of the air inlet pipe. A filtration chamber cover located on the top of the waste gas treatment device housing is movably installed on the top of the air inlet pipe valve. A heating fan installation housing is fixedly installed on the right side of the filtration chamber cover. A heating fan air inlet hole is opened on the top of the heating fan installation housing. A cooling fan installation housing is fixedly installed on the right side of the heating fan air inlet hole. A water outlet pipe located on the right side of the waste gas treatment device housing is fixedly installed on the right side of the cooling fan installation housing. Support feet located at the bottom of the waste gas treatment device housing are fixedly installed at the bottom of the water outlet pipe. A filtration chamber is opened inside the waste gas treatment device housing. A particle filter screen fixing frame is fixedly installed inside the filtration chamber. A particle filter screen is movably installed inside the particle filter screen fixing frame. A support seat is fixedly installed at the bottom of the particle filter screen. A heating fan located inside the heating fan installation housing is fixedly installed on one side of the support seat. The bottom of the heating fan is connected and installed with a hot air pipeline. The bottom of the hot air pipeline is connected and installed with a heating chamber. A cooling fan located inside the cooling fan installation housing is fixedly installed on one side of the heating chamber. The bottom of the cooling fan is connected and installed with a cold air pipeline. The bottom of the cold air pipeline is connected and installed with a cooling chamber. By installing devices such as a heating fan, a heating chamber, a cooling fan, and a cooling chamber, the purpose of liquefying waste gas, preventing harmful substances from mixing into the air, and having high working efficiency is achieved. This device performs two-layer heat and cold treatment on the waste gas to quickly liquefy the waste gas, prevent harmful substances from mixing into the air. The temperature of the waste gas will drop when passing through the filtration chamber through the air inlet pipe. It is heated through the heating chamber and then quickly cooled through the cooling chamber to achieve liquefaction. The heating treatment can reduce the cooling time, thus achieving the purpose of high working efficiency.

[0004] The above technical solution introduces the waste gas generated during the processing of environmental protection materials through the intake pipe for treatment, but no improvement has been made on how to collect the waste gas. At present, there is no closed hood in the environmental protection material processing section, and the odor (such as methanethiol) diffuses quickly. The capture rate of the traditional side suction hood is only about 50%, and it is impossible to comprehensively capture the waste gas generated during processing, resulting in low waste gas treatment efficiency. The un-captured waste gas diffuses in the processing space, leading to a poor working environment.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] (1) A waste gas treatment device for environmentally friendly material processing, which fully surrounds the material outlet of the processing equipment through a gas collecting hood mechanism, and forms a fence through a front curtain mechanism and a door panel mechanism, so that the waste gas generated by the material outlet of the processing equipment can be fully collected, thereby improving the comprehensiveness of waste gas collection, avoiding leakage of waste gas when it is introduced into the treatment device, and improving the safety of the working environment.

[0027] (2) A waste gas treatment device for processing environmentally friendly materials, wherein a door curtain assembly of a front curtain mechanism is arranged, and the lower side of the curtain shaft is evenly and equidistantly movably sleeved with sheet curtains, and adjacent sheet curtains are fixedly connected with connecting curtains. When environmentally friendly materials are produced from the door curtain assembly, the door curtain assembly can adapt to the environmentally friendly materials as much as possible to reduce the space for extra leakage to cause waste gas to overflow, thereby improving the ability to prevent waste gas leakage.

[0028] (3) An exhaust gas treatment device for processing environmentally friendly materials. Through the movable installation of the door panel mechanism, when the processing equipment stops operating, the door panel mechanism can be rotated synchronously to close the door opening. In this state, the first fan mechanism and the second fan mechanism continue to guide the airflow, so that the exhaust gas remaining in the processing equipment can be discharged, further improving the use safety.

[0029] (4) An exhaust gas treatment device for processing environmentally friendly materials. A stable and directionally flowing "outward supply and upward discharge" airflow is formed in the air collection hood mechanism, thereby improving the exhaust gas circulation rate. At the same time, the fresh air introduced by the first fan mechanism can effectively dilute the odor concentration of the exhaust gas.

[0030] (5) An exhaust gas treatment device for processing environmentally friendly materials. The fresh air is introduced into the air collection hood mechanism after contacting the cooling cylinder with internal cold water, thereby cooling the high-temperature exhaust gas in the air collection hood mechanism, ensuring the activity of the subsequent treatment bacteria agent, reducing the temperature of the exhaust gas, thereby slowing down the heat damage of the device components and improving the service life.

[0032] (7) An exhaust gas treatment device for processing environmentally friendly materials. The treatment pipe mechanism slowly infiltrates the sponge with the bacteria agent to form a biofilm layer, improving its ability to resist airflow erosion and its service life. At the same time, the treatment pipe mechanism fits with the second fan mechanism and the first treatment mechanism to conduct temperature through the outer heat conduction cylinder, solving the problem of bacteria agent dormancy and improving the treatment reliability.

[0033] (8) An exhaust gas treatment device for processing environmentally friendly materials. The cleaning tank cleans the second nozzle on one side to prevent its port from being blocked. When the grinding block rotates one week and contacts the pulley again, the tube assembly is driven to rotate 180 degrees, switching the second nozzles on both sides of it, and cooperating with the cleaning of the second nozzle by the cleaning tank to improve the automatic self-cleaning ability.

[0070] The working principle of the present invention is as follows:

[0071] The discharge port of the processing equipment is fully surrounded and hooded by the gas collecting hood mechanism 1, and a fence is formed by the front curtain mechanism 2 and the door panel mechanism 3, so that the exhaust gas generated by the discharge port of the processing equipment can be fully collected, thereby improving the comprehensiveness of exhaust gas collection, avoiding leakage of exhaust gas when it is introduced into the treatment device, and improving the safety of the working environment.

[0072] By setting the door curtain assembly of the front curtain mechanism 2, the lower side of the curtain shaft 204 is equidistantly and evenly movably sleeved with sheet curtains 205, and adjacent sheet curtains 205 are commonly fixedly connected with connecting curtains 206. When the environmentally friendly material is produced from the door curtain assembly, the door curtain assembly can adapt to the environmentally friendly material as much as possible to reduce the space for extra air leakage to cause the exhaust gas to overflow, thereby improving the ability to prevent exhaust gas leakage.

[0073] Through the movable installation of the door panel mechanism 3, when the processing equipment stops operating, the door panel mechanism 3 can be synchronously rotated to close the door opening 102. In this state, the first fan mechanism 4 and the second fan mechanism 5 continue to guide the air flow, so that the waste gas remaining in the processing equipment can be discharged, further improving the use safety.

[0074] The second fan mechanism 5 is installed on the air collecting hood mechanism 1. The waste gas in the air collecting hood 101 is collected by the second fan 502 and the third fan 504. In addition, the first fan mechanism 4 installed on the door panel mechanism 3 introduces external air into the air collecting hood 101, so that a stable and directionally flowing "external supply and upper discharge" air flow is formed in the air collecting hood mechanism 1, thereby improving the flow rate of the waste gas. At the same time, the fresh air introduced by the first fan mechanism 4 can effectively dilute the odor concentration of the waste gas.

[0075] The first connecting pipe 408 and the second connecting pipe 410 are externally connected to cold water. While the fan 404 rotates to guide air into the air collecting hood mechanism 1, the inner fan 407 rotates to introduce cold water from the second connecting pipe 410 and discharge it from the first connecting pipe 408. The fresh air is introduced into the air collecting hood mechanism 1 after contacting the cooling cylinder 406 with built-in cold water, thereby cooling the high-temperature waste gas in the air collecting hood mechanism 1, ensuring the activity of the subsequent treatment bacterium agent, reducing the temperature of the waste gas, slowing down the heat damage of the device components, and improving the service life.

[0076] Through the setting of the treatment component, the traditional passive collection of waste gas is transformed into active degradation, realizing the function of collecting and treating waste gas simultaneously, and improving the treatment capacity of waste gas.

[0077] Through the setting of the guide vane 604 of the first treatment mechanism 6, the bacterium agent sprayed by the first nozzle 603 is guided from top to bottom along the guide vane 604, and the waste gas is guided from bottom to top along the guide vane 604, so that the bacterium agent and the waste gas are fully collided and contacted under the guidance of the guide vane 604, prolonging the contact time between the waste gas and the bacterium agent and improving the biodegradation rate of the waste gas.

[0078] The waste gas treated by the first treatment mechanism 6 is introduced into the second treatment mechanism 8 through the treatment pipe mechanism 7 for further treatment. The treatment pipe mechanism 7 forms a biofilm layer by slowly infiltrating the bacterium agent into the sponge 702, improving its ability to resist air flow erosion and its service life. At the same time, the treatment pipe mechanism 7 is attached to the second fan mechanism 5 and the first treatment mechanism 6 and uses the outer heat conduction cylinder 704 for temperature conduction, solving the problem of bacterium agent dormancy and improving the treatment reliability.

[0079] The exhaust gas is introduced into the second treatment mechanism 8 for full surrounding spraying. The outer cylinder 804 is externally connected to a power source through a belt groove 805 and rotates.
