Abstract
Description
Technical Field
[0001] This utility model relates to the field of waste gas treatment technology, and in particular to a workshop waste gas treatment device. Background Technology
[0002] Production workshops often contain a lot of dust or harmful gases. To ensure worker health and emission safety, the waste gas generated in the workshop needs to be treated. In the existing technology, most purification devices are set up outside the workshop or connected to a unified purification system for unified treatment. Large purification systems are bulky, occupy a large area, require a large space for arrangement, and are far away from the workshop, so they cannot treat the waste gas generated in time. On the other hand, purification devices set up outside the workshop can only capture particulate matter and cannot purify chemical components. Direct emission may result in pollutants exceeding the standard. Utility Model Content
[0003] To overcome the shortcomings of existing technologies, this utility model provides a workshop exhaust gas treatment device, which effectively solves the problems of incomplete workshop exhaust gas treatment and excessively large and inconvenient treatment equipment.
[0004] The technical solution to the technical problem is: a workshop exhaust gas treatment device, including a body, a spraying mechanism at the upper part of the body, an air inlet pipe at the bottom of the body, a cone top at the upper end of the air inlet pipe, a baffle extending downward from the circumference of the cone top, multiple through holes on the outside of the air inlet pipe, a neutralizing liquid in the body, the liquid level of the neutralizing liquid being higher than the baffle and lower than the through holes, an exhaust port at the top of the body, and a filter screen plate at the end of the air inlet pipe.
[0005] Preferably, the bottom of the machine body is provided with a drain port, and a valve is provided on the drain port.
[0006] Preferably, the spraying mechanism includes a spray pipe passing through the top of the machine body, the lower end of the spray pipe being located inside the machine body and connected to a spray head, and multiple nozzles being provided at the bottom of the spray head.
[0007] Preferably, the intake pipe is equipped with a one-way valve.
[0008] Preferably, the air inlet pipe is provided with a receiving box located at the bottom of the filter plate.
[0009] Preferably, the filter plate is inserted into the air intake pipe.
[0010] This utility model has a simple and ingenious structure, is easy to use, and can be placed outside the workshop to treat the workshop's exhaust gas in real time. The exhaust gas undergoes dual treatment of physical filtration and chemical purification, so that the emitted air meets the emission standards and avoids air pollution. Attached Figure Description

[0014] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.
[0015] Depend on Figures 1 to 3 It is known that a workshop exhaust gas treatment device includes a body 1, a spraying mechanism is provided at the top inside the body 1, an air inlet pipe 2 is provided at the bottom inside the body 1, a cone 3 is provided at the top of the air inlet pipe 2, a baffle 4 extends downward from the circumference of the cone 3, a plurality of through holes 5 are provided on the outside of the air inlet pipe 2, a neutralizing liquid is contained inside the body 1, the liquid level of the neutralizing liquid is higher than the baffle 4 and lower than the through holes 5, an exhaust port 6 is provided at the top of the body 1, and a filter plate 7 is provided at the end of the air inlet pipe 2, the filter plate 7 is inserted into the air inlet pipe 2.
[0016] In practical use, this utility model
[0017] The device is placed outside the workshop and connected to the air inlet pipe 2 through the gas collection device, so that the exhaust gas in the workshop enters the machine body 1. The machine body 1 is sprayed with neutralizing liquid through the spray mechanism. A portion of the neutralizing liquid is reserved at the bottom of the machine body 1. The exhaust gas enters the bottom of the cone top 3 through the through hole 5 on the air inlet pipe 2 and then dissolves into the neutralizing liquid. The pollutants contained in the exhaust gas are neutralized by the neutralizing liquid, eliminating the harmful gases in the exhaust gas. The remaining gas is discharged to the outside through the exhaust port 6.
[0018] After entering the intake pipe 2, the exhaust gas will first be filtered by the filter screen 7 to remove solid particles. The neutralizing liquid will then purify the harmful gases in the exhaust gas. Through the combination of these two methods, the emitted air meets the emission standards and avoids air pollution.
[0019] The bottom of the body 1 is provided with a drain port 8, and a valve 9 is provided on the drain port 8. When the neutralizing liquid is saturated, it is discharged from the drain port 8, and then the spraying mechanism replenishes the neutralizing liquid.
[0020] The spraying mechanism includes a spray pipe 10 that passes through the top of the body 1. The lower end of the spray pipe 10 is located inside the body 1 and is connected to a spray head 11. The bottom of the spray head 11 is provided with multiple nozzles 12. During the normal purification process, the spraying mechanism can also be used to intermittently spray the inside of the body 1 to prevent the release of harmful gases.
[0021] The intake pipe 2 is equipped with a one-way valve 13, which allows the intake pipe 2 to only deliver liquid into the body 1 and not to discharge it in the opposite direction. Therefore, the pressure in the space at the bottom of the cone 3 will be greater than the external pressure of the cone 3, and the liquid level of the neutralizing liquid inside the cone 3 will be lower than the liquid level of the neutralizing liquid outside. Even if the spray system sprays too much neutralizing liquid, it can prevent the neutralizing liquid from entering the intake pipe 2 through the through hole 5, thus preventing the neutralizing liquid from damaging the intake pipe 2.
[0022] The air inlet pipe 2 is equipped with a receiving box 14 located at the bottom of the filter plate 7. During processing, the filter plate 7 can be vibrated to make the particles on the filter plate 7 fall into the receiving box 14. At the same time, the filter plate 7 can be replaced and the receiving box 14 can be cleaned.
[0023] Compared with the prior art, this utility model has the following advantages: it can physically filter and chemically purify workshop exhaust gas, ensuring that the emitted air meets the standards, avoiding air pollution, and meeting emission standards. It does not require investment in a large-scale purification system, which can reduce production costs.
