Embodiment approach 1

[0037] According to the exhaust gas discharge of the buffer container 6, the number of openings of the secondary purification treatment device 4 is manually controlled, so that the total working exhaust volume of the secondary purification treatment device 4 matches the exhaust gas discharge of the buffer container 6.

Embodiment approach 2

[0039]In order to measure the waste gas displacement of the buffer container 6, automatically control the opening quantity of the secondary purification treatment device 4, measure each waste gas inlet of the buffer container 6 (also can be at the outlet of each primary treatment facility 2, or each one On the outlet of the primary treatment facility 2 and the connection pipeline 3 of the buffer container 6) flow sensors 7 are set, and each flow sensor 7 is connected with a system controller (not shown) signal, and the system controller controls the secondary purification treatment device 4 start and stop.

[0040] When the system controller detects that the total flow of exhaust gas flowing into the buffer container 6 does not match the total working exhaust volume of the working secondary purification treatment device 4 through the flow sensor 7, the working exhaust of the working secondary purification treatment device 4 is adjusted. Gas volume or the quantity of secondary ...

Abstract

A paint-contained air treating system for the painting rooms is composed of more than two sets of stage-one air treating unit, one set for one painting room, a stage-two air cleaning unit with an exit communicated to atmosphere, and a buffer container connected between said air treating units and air cleaning unit for the flow matching.

Description

technical field [0001] The invention relates to a paint waste gas treatment system and a paint waste gas treatment method, more specifically, to a paint waste gas treatment system used in a container or special vehicle production line paint room and a paint waste gas treatment method using the system. Background technique [0002] On a production line of containers or special vehicles, several paint rooms are usually arranged to meet production needs. As shown in Figure 1, at present, the treatment of paint waste gas from paint rooms usually involves a treatment system 10 for each paint room, and a large amount of paint mist and harmful gases generated by paint room 1 pass through primary treatment facilities 2 (such as water curtain, water cyclone or other paint mist treatment devices, etc.) clean the paint mist, and then pass through the secondary purification treatment facility 4 to clean the harmful gas, and discharge it into the atmosphere through the discharge port 5 a...
