Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to an environmentally friendly waste gas treatment device. Background Art

[0002] Waste gas purification mainly refers to the work of treating industrial waste gas such as dust particles, flue gas, odorous gases, and toxic and harmful gases generated in industrial places. Common waste gas purification includes factory smoke waste gas purification, workshop dust waste gas purification, organic waste gas purification, waste gas odor purification, acid and alkali waste gas purification, chemical waste gas purification, etc. Waste gas contains a large amount of water-soluble substances and other toxic and harmful substances that are not water-soluble. Bag dust collectors are usually used to separate and collect particulate matter in the waste gas, and then purification equipment is used to purify and absorb the harmful components in the waste gas, so that the exhaust gas can meet the emission standards required by environmental protection.

[0003] However, the particles cleaned out by the existing bag dust collector are generally accumulated next to the bag dust collector. Since the particles are relatively scattered, they fly with the air and easily cause pollution to the workshop. In addition, the scattered particles are easy to fly, which is not conducive to transportation. The particles also occupy a large area when piled up, which is not conducive to storage.

[0004] The existing Chinese patent with the announcement number CN219630943U discloses an environmental waste gas treatment device. The environmental waste gas treatment device includes: a bag dust collector, a fan, a particle filter and a purified water tank; an air inlet pipe is provided at one end of the bag dust collector, a plurality of waste discharge ports are provided at the bottom of the bag dust collector, the bottom end of the waste discharge port is connected to a screw conveyor, a compression mechanism is provided below the screw conveyor, and the screw conveyor is connected to the compression mechanism.

[0005] In view of the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: when the device is compressed by moving the push plate, some of the particles that fall down will stay behind the moving square of the push plate, thereby producing corresponding cleaning dead corners, making it impossible for some particles to be discharged smoothly, and improvement is needed; therefore, an environmentally friendly exhaust gas treatment device is proposed to address the above problems.
