Description

Technical Field

[0001] This utility model belongs to the technical field of spray booths, specifically relating to a large steel pipe spray booth structure. Background Technology

[0002] Large steel pipes are often used in petrochemical, power, and water supply and drainage industries, which all have corresponding requirements for the corrosion resistance of large steel pipes.

[0003] In the anti-corrosion process of large steel pipes, after rust removal, processes such as painting or powder coating are applied. However, these processes cause air pollution. To solve this problem, exhaust gas treatment devices were installed in the workshop, but their actual effectiveness was poor. The main reason is that the workshop space is large, and the fans used to send air from the workshop into the exhaust gas treatment device can only draw air from the vicinity of the fan and cannot circulate the air within the workshop. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a large steel pipe spraying booth structure to solve the technical problems of large space, poor air circulation effect, and poor air purification effect in the existing spraying workshop.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A large steel pipe spraying booth structure, comprising:

[0006] A spray booth frame, the spray booth frame comprising at least four columns, the tops of the four columns being connected by several crossbeams;

[0007] A multi-faceted curtain wall, wherein the multi-faceted curtain wall is mounted on the frame of the spray booth;

[0008] The spraying area is located inside the spraying booth;

[0009] A mist dispersion zone, which is arranged in parallel with the spraying zone;

[0010] Several exhaust fans and fresh air fans are provided. The exhaust fans are provided at both ends of the spraying area, the fresh air fan is provided at one end of the misting area, and the exhaust fans are provided at the other end. The air outlet of the exhaust fans is connected to the exhaust gas treatment device through a pipe.

[0011] This invention, by setting up a fresh air fan and an exhaust fan, with the fresh air fan and the exhaust fan in relative positions, ensures that fresh air flows from one side of the spray booth to the other, and can bring the internal air into the exhaust fan together, accelerating the air flow and improving the purification effect of the internal air.

[0012] Furthermore, an oxygen sensor is provided on the side of the fog dispersing zone where the extraction fan is located, and the oxygen sensor is electrically connected to the control switch of the curtain wall.

[0013] The benefits of this step include: detecting the oxygen content in the internal air using an oxygen sensor; if the oxygen level is too low, the curtain wall cannot be opened, thus avoiding any threat to personal safety.

[0014] Furthermore, a middle crossbeam is provided between the two crossbeams, and a paddle fan is suspended in the center of the middle crossbeam.

[0015] The beneficial effects of this step are: the mixing of fresh air and exhaust gas by the paddle fan balances the air pressure throughout the spray booth.

[0016] Furthermore, the waste gas treatment device includes a dry filter, a catalytic pyrolysis furnace, and an adsorption box connected in sequence, and a circulating fan is also provided between the catalytic pyrolysis furnace and the adsorption box.

[0017] The beneficial effect of this step is that it renders the waste gas harmless.

[0018] Furthermore, the curtain wall is also equipped with windows.

[0019] The benefit of this step is that you can observe the level of air pollution inside the room through the window.

[0020] The beneficial effects of this utility model are:

[0021] This application proposes to create a closed space within the workshop using the frame and curtain wall of a spray booth. This space is much smaller than the workshop itself. Within this closed space, air is introduced at one location and vented at multiple locations. This accelerates the internal airflow, facilitates the removal of polluted air, and then sends it to an exhaust gas treatment device for harmless treatment, thereby improving the air purification effect.

[0039] A misting zone 11 is provided in parallel with the spraying zone 10. When there is only one spraying zone 10, there may be one or two misting zones 11, located on one or both sides of the spraying zone 10. When there are multiple spraying zones 10 and misting zones 11, they are arranged alternately. The misting zone 11 can prevent the paint or powder in the air of the spraying zone 10 from being too dense.
