[0002] The statements in this section are merely background information related to this application and do not necessarily constitute prior art.

[0003] During the production, dilution, filling, and subsequent product molding processes of unsaturated polyester resin, such as mixing, coating, and curing, large amounts of organic waste gas containing styrene, alcohols, ethers, low-molecular-weight monomers, and intermediates are continuously or intermittently emitted. This waste gas is characterized by large concentration fluctuations, low oxygen content, high moisture content, pronounced odor, and a certain risk of combustion and explosion. Early methods commonly used, such as direct discharge from heat transfer fluid furnaces or simple water spraying, not only have low treatment efficiency and high energy consumption, but also cannot recover useful components from the waste gas, easily leading to secondary pollution and safety hazards.

[0024] In some embodiments, a protective cylinder 6 is provided outside the motor 5, and a guide strip 7 is provided outside the protective cylinder 6; one side of the protective cylinder 6 is fixedly connected to the protective rear plate 8; the outer side of the protective rear plate 8 and the outer side of the protective cylinder 6 away from the protective rear plate 8 are both fixedly connected to the first processing tube 1 through several connecting rods 9. In some embodiments, the protective cylinder 6 is fixedly provided with a protective front plate on one side of the motor shaft of the motor 5, and a through hole is provided in the middle of the protective front plate, and the motor shaft of the motor 5 is rotatably disposed in the through hole.

[0025] In some embodiments, the waste residue box 3 is located below the protective rear plate 8. The waste residue box 3 includes a box body and an insert plate 33; the top of the box body has an upper opening and the bottom has a lower opening; the upper opening is connected to the first processing pipe 1; the insert plate 33 is inserted into the bottom of the box body.

[0026] A slot 31 is provided on one side of the box, and an inner groove 32 is provided inside the box; the insert plate 33 is inserted into the box through the slot 31 and then connected to the inner groove 32.

[0027] In some embodiments, the insert plate 33 is provided with a baffle 34 on the outside, and the baffle 34 is provided with a mounting hole; the box body is provided with a mounting threaded hole above the slot 31 that mates with the mounting hole; the insert plate 33 is fixed to the box body by passing the tightening screw 35 through the mounting hole and screwing it into the mounting threaded hole.

[0029] Working principle: Unsaturated resin exhaust gas enters through the exhaust gas inlet of the first treatment pipe 1. Water is sprayed from the spray pipe 12 and atomized under the action of the umbrella-shaped diverter head 11, adsorbing large dust particles in the exhaust gas to form a "water flow" mixed with large dust particles. This "water flow" is guided to the rear end of the motor 5 through the guide strip 7. Since the end of the first treatment pipe 1 is a curved pipe structure with an upward orientation, the "water flow" will eventually enter the waste residue box 3. This completes the adsorption of large dust particles in the unsaturated resin exhaust gas.

[0030] The unsaturated resin waste gas treatment device of this application has a wide range of applications, especially suitable for factories and workshops with large areas, closed environments, or poor air permeability. During use, it can be used to absorb ambient gases through the first treatment pipe, or connected to the waste gas pipeline after unsaturated resin processing, or a dust collection hood can be installed before the first treatment pipe to treat the unsaturated resin waste gas, depending on the site requirements. The treatment effect is good because the first treatment pipe removes large dust particles from the waste gas, reducing the likelihood of subsequent filter clogging. Furthermore, if subsequent processes require further purification of the waste gas with activated carbon, this device facilitates further purification with activated carbon, reducing the frequency of activated carbon refining. During the waste gas treatment process, the atomization effect of the spray pipe collects large dust particles in the waste gas into a residue box. The residue box can be cleaned periodically without needing to clean the inside of the first treatment pipe, making it convenient to use.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
