Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, specifically to an environmental waste gas treatment device. Background Technology

[0002] Air quality is essential for human survival and also a major medium for disease transmission. As people become more environmentally conscious and their living standards improve, they are increasingly aware of the importance of clean air for their health. Waste gas treatment is the pretreatment of waste gas generated in industrial sites and factory workshops before it is discharged into the environment.

[0003] Existing air environment treatment exhaust gas treatment devices still have some shortcomings that need to be improved. When exhaust gas is introduced, a filter screen is usually required for pre-filtration. After long-term use, the filter screen is easily clogged and cannot be replaced or cleaned regularly, which makes it inconvenient to use. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figures 1 to 3This utility model provides a technical solution: an environmental waste gas treatment device, including an upper cylinder 1 and a lower cylinder 2 installed at the bottom of the upper cylinder 1. Multiple air inlet pipes 7 are threadedly inserted into the circumferential side wall at the top of the upper cylinder 1. The air inlet pipes 7 are distributed at equal intervals around the circumference. An air inlet mesh 8 is fixedly connected to the end of the air inlet pipe 7 away from the upper cylinder 1. A support bar 14 is fixedly connected between the inner walls of the lower cylinder 2. A filter element 10 is placed on the support bar 14. A fan 11 is fixedly connected between the inner walls of the lower cylinder 2. The fan 11 is located below the support bar 14.

[0023] The intake pipe 7 is installed on the circumferential side wall of the upper cylinder 1 by means of threaded connection. By setting the intake net 8, large solid particles in the exhaust gas can be intercepted and filtered. When there are too many particles on the surface of the intake net 8 and it causes blockage, the intake pipe 7 is removed from the side wall of the upper cylinder 1, and then the intake net 8 and intake pipe 7 are cleaned to remove residual particles and ensure normal air intake and ventilation.

[0024] The upper cylinder 1 and the lower cylinder 2 are respectively fixedly connected to an upper collar 6 and a lower collar 3 at their close ends. Multiple limiting posts 4 are fixedly connected to the top of the lower collar 3. Multiple limiting holes 601 are opened on the upper collar 6. The limiting posts 4 pass through the limiting holes 601 and are threaded with nuts 5.

[0025] The upper cylinder 1 and the lower cylinder 2 are connected in a detachable manner, which allows for easy replacement of the filter element 10. When disassembling, each nut 5 is unscrewed from the limiting post 4, and then the limiting post 4 is removed from the limiting hole 601, thereby achieving the separation of the upper cylinder 1 and the lower cylinder 2.

[0026] The bottom of the lower cylinder 2 is threaded with an exhaust hood 12, which has multiple through holes.

[0027] An exhaust hood 12 is threadedly installed at the bottom of the lower cylinder 2 to prevent dust from entering the lower cylinder 2 through the bottom. At the same time, a through hole is provided to facilitate the discharge of gas treated by the filter element 10.

[0028] The bottom of the lower cylinder 2 is fixedly connected to multiple circumferentially distributed support legs 13 to support the entire device.

[0029] A pressure ring 9 is fixedly connected to the inner wall of the upper cylinder 1. The pressure ring 9 is used to press and fix the filter element 10. A rubber pad is fixedly connected to the bottom of the pressure ring 9. The rubber pad can compensate for the gap between the pressure ring 9 and the filter element 10, thereby ensuring that the filter element 10 can be stably pressed.

[0030] The end of the air intake pipe 7 away from the upper cylinder 1 is flared, which increases the air intake area at the air intake end and allows for full intake and treatment of exhaust gas.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
