Description

Technical Field

[0001] The utility model belongs to the technical field of polyphenylene sulfide production, and in particular relates to a waste salt treatment flue gas purification device for polyphenylene sulfide production. Background Art

[0002] Polyphenylene sulfide is a new type of high-performance thermoplastic resin with excellent high temperature resistance, corrosion resistance, radiation resistance, flame retardancy, balanced physical and mechanical properties, excellent dimensional stability and excellent electrical properties. It is widely used as a structural polymer material and is widely used as a special engineering plastic after filling and modification.

[0003] The existing flue gas purification device does not adsorb the particulate impurities inside the flue gas when purifying the polyphenylene sulfide waste salt flue gas, resulting in unsatisfactory flue gas purification effect. In addition, there is no efficient sulfide spray contact treatment, and the sulfide inside the flue gas cannot be solved accordingly.

[0004] The utility model of Chinese patent application number CN202120638946.6 discloses a flue gas purification device for treating waste salt for polyphenylene sulfide production, comprising an adsorption bin, a fan is arranged at an outer side position of the adsorption bin, an output end of the fan is connected to a smoke collecting box, a smoke inlet is opened on the top of the smoke collecting box, an air inlet pipe is fixedly connected to an outer side position of the smoke collecting box, and a base is fixedly connected to the bottom of the adsorption bin in a horizontal direction. The utility model is provided with a pre-treatment adsorption bin, which can suck the flue gas generated by the external treatment of polyphenylene sulfide waste salt into the bin body under the power provided by the driving device, and pre-adsorb the small particulate matter in the waste salt flue gas, and after the small particulate impurities in the flue gas are adsorbed, the effect of the subsequent desulfurization and purification treatment of the flue gas can be greatly improved, thereby increasing the working efficiency and quality of the purification device;

[0005] However, from the drawings in the specification, it can be learned that the adsorption plate is controlled by a motor to rotate inside the adsorption bin to achieve adsorption of small particle impurities inside the flue gas. However, when in use, only the adsorption plate is rotated inside the adsorption bin, which may cause the incoming flue gas to be directly discharged into the interior of the spray tower, resulting in poor quality of small particle impurity removal, which may easily affect the subsequent flue gas treatment effect.
