Description

Technical Field

[0001] This utility model relates to the field of trichloroacetone condensation and recovery technology, and in particular to a trichloroacetone condensation and recovery device. Background Technology

[0002] Trichloroacetone, as an important chemical raw material and organic synthesis intermediate, is widely used in pesticides, pharmaceuticals, and dyes. However, its production and use generate a large amount of waste gas and liquid containing trichloroacetone. These substances are toxic and volatile, and direct discharge will cause serious harm to the environment and human health. With increasingly stringent environmental regulations, how to effectively recycle and treat trichloroacetone has become a technical problem that chemical companies need to solve. Traditional treatment methods often have problems such as low recycling efficiency, high energy consumption, or secondary pollution. Therefore, developing a highly efficient and environmentally friendly trichloroacetone condensation and recovery device is of great practical significance.

[0003] The common trichloroacetone recovery devices in the existing technology mainly adopt the principle of condensation separation combined with physical adsorption. Its core structure usually includes components such as condenser, gas-liquid separation tank and exhaust system. The condenser mostly adopts shell and tube type or plate heat exchanger, which condenses the trichloroacetone vapor in the exhaust gas into liquid through circulating cooling medium.

[0004] The main problem with existing technologies is that a large amount of harmful substances such as chloroacetone remain in the gas after gas-liquid separation. Direct emission of these substances would cause serious air pollution. Due to the lack of an effective secondary adsorption treatment mechanism, traditional devices often simply discharge the gas directly into the atmosphere through a simple exhaust pipe after separation, resulting in a large amount of volatile organic compounds not being effectively treated. This direct emission method not only fails to meet current environmental standards but also causes continuous pollution to the surrounding environment. Especially in the case of large-scale chloroacetone production, the emission of untreated harmful gases will significantly increase the environmental risks of enterprises. At the same time, with the continuous improvement of environmental regulatory requirements, this treatment method is no longer able to meet the strict requirements of modern chemical production for waste gas treatment. Therefore, a chloroacetone condensation and recovery device is proposed to solve the above problems. Utility Model Content

[0038] Working principle: When the 3-chloroacetone condensation and recovery device is working, the mixed gas containing 3-chloroacetone vapor enters the condenser tube 7 inside the condenser 2 through the inlet 6. The condenser 2, which is fixedly connected to the top of the pad 1, provides space for the condensation process. The transfer pump 4, which is fixedly connected to the top of the condenser 2, starts, driving the mixed gas in the condenser tube 7 to flow towards the input end of the transfer pump 4. After being pressurized by the transfer pump 4, it is transported to the separation tank 3 through the gas-liquid pipe 5, realizing the initial separation of gas and liquid. In the separation tank 3, the gas moves upward and is discharged through the exhaust frame 8, which is fixedly connected to the top. The sliding frame 12, which is slidably connected inside the exhaust frame 8, drives the internal fixed connection The adsorption plate 11 adsorbs harmful substances such as residual trichloroacetone in the gas. When the adsorption plate 11 needs to be replaced, the handle 17 is rotated. The handle 17 drives the sliding column 15 to slide inside the hollow frame 13, thereby driving the positioning column 14 to disengage from the sliding frame 12. The sliding frame 12 can then be removed from the exhaust frame 8. The trichloroacetone liquid separated from the separation tank 3 enters the filter frame 10 through the liquid outlet pipe 9 fixedly connected to the side wall. The sliding frame 18 drives the filter screen 19 fixedly connected inside to intercept and filter impurities in the liquid. The filtered liquid is discharged and collected through the liquid outlet pipe 22 fixedly connected to the bottom of the filter frame 10. When the filter screen 19 needs to be cleaned or replaced, pull the lever 26. The lever 26 slides in the L-shaped groove 24, which drives the sliding plate 25 to slide inside the hollow column 21, compressing the second spring 27. This causes the locking post 23 to disengage from the groove 20 on the side wall of the second sliding frame 18, allowing the second sliding frame 18 to be pulled out of the filter frame 10. This achieves efficient condensation and recovery of trichloroacetone, while ensuring the environmental friendliness of the emitted gas and the high purity of the recovered liquid.
