Abstract
Description
Technical Field
[0001] This utility model relates to the field of waste gas treatment technology, specifically to a waste gas treatment and purification device for electroplating. Background Technology
[0002] Electroplating is a process that uses the principle of electrolysis to plate a thin layer of other metals or alloys onto the surface of some metals. It is a process that uses electrolysis to attach a metal film to the surface of metal or other material parts, thereby preventing metal oxidation, improving wear resistance, conductivity, reflectivity, corrosion resistance, and enhancing aesthetics. Electroplating generally involves placing the metal object to be plated into an electrolytic tank containing the corresponding electrolyte. During the electrolysis process, a large amount of electroplating waste gas containing heavy metals is generated.
[0003] A search revealed a Chinese patent application (application number 201921549851.6) disclosing a purification device for treating exhaust gas from an electroplating chamber. The device includes an electroplating chamber with a through-hole connected to a gas collection box. A sleeve is fitted into the through-hole, and a second exhaust fan is fixed within the sleeve. This purification device for treating exhaust gas from an electroplating chamber has multiple second exhaust fans installed in the electroplating chamber. These fans collect exhaust gas from various locations within the gas collection box. A first exhaust fan discharges the exhaust gas from the gas collection box through an exhaust pipe and a connecting pipe. During the discharge process, the exhaust gas comes into contact with an activated carbon storage bag and is purified. A second turntable, driven by a motor, rotates to promptly replace a section of the saturated activated carbon storage bag.
[0004] However, existing patents have the following drawbacks:

The first three-way valve 7 is connected to multiple second three-way valves 18 through pipes for controlling the direction of gas flow. A purification box 3 is provided on the upper end of the vehicle body 2 for treating and purifying the exhaust gas. Multiple second air pumps 16 are connected to both sides of the purification chamber 3 to extract the gas inside the second neutralization chamber 15 and enter the purification chamber 3 for purification. The second air pumps 16 are connected to the second neutralization chamber 15 through pipes located on the inner wall of the second neutralization chamber 15 near the top cover. The second neutralization chamber 15 contains neutralizing liquid for secondary neutralization of the waste gas. The second neutralization chamber 15 has a second liquid level scale 13 for marking the volume of neutralizing liquid added. A second transparent glass 14 is provided on the other side of the second neutralization chamber 15 so that personnel can visually determine the gas flow rate by observing the bubbles. The upper end of the second neutralization chamber 15 is connected to a second three-way valve 18 through a pipe.

[0030] Specifically, the bottom of the vehicle body 2 is provided with several wheels 1.

[0032] Specifically, the purification box 3 is equipped with a partition plate 25 inside, and several maintenance doors 4 are detachably installed at both ends of the purification box 3.
[0033] To solve the problem of internal space partitioning, such as Figure 1 , 3 As shown, the purification box 3 is equipped with a partition 25 to divide the internal space. Several inspection doors 4 are detachable at both ends of the purification box 3 to facilitate the replacement, maintenance and upkeep of internal components.
[0034] Specifically, several mesh frames 24 are respectively arranged in the internal partition area of the purification box 3, and several fixing blocks 22 are arranged on one side of the mesh frame 24.
[0035] To solve the problems of space frame installation, such as Figure 3 As shown, several mesh frames 24 are respectively set in the internal partition area of the purification box 3.

[0037] To address the issue of adsorption purification after neutralization of waste gas, such as Figure 3 As shown, activated carbon adsorption layers 23 are provided between the mesh frames 24 for adsorbing and purifying the neutralized waste gas.
[0038] Specifically, a detector 5 is installed at the top of the corresponding partition area inside the purification box 3, and an air outlet pipe 6 is installed on one side of the detector 5.
[0039] To address the issue of whether the purified gas meets the standards, such as Figure 1As shown, detectors 5 are installed at the top of the corresponding partitioned areas inside the purification chamber 3 to detect whether the purified gas meets the standards, preventing the activated carbon adsorption layer 23 and the neutralization liquid from becoming saturated. Since there are several second neutralization chambers 15 and activated carbon adsorption layers 23, some devices can be opened for purification as needed through multiple three-way valves. When the detector 5 detects that the purified gas does not meet the standards, the original working device is closed through the three-way valve, and another non-working device is opened for purification, which improves the detection efficiency and facilitates the replacement of saturated purification components. The detector 5 is a commonly used instrument in the existing technology, so it will not be described in detail. An outlet pipe 6 is provided on one side of the detector 5 for gas output.
