Description

Technical Field

[0001] The utility model belongs to the technical field of pharmaceutical intermediate production, and particularly relates to a treatment device for tail gas from pharmaceutical intermediate processing. Background Art

[0002] The so-called pharmaceutical intermediates are actually some chemical raw materials or chemical products used in the process of drug synthesis. This kind of chemical product does not require a drug production license and can be produced in an ordinary chemical plant. As long as it reaches a certain level, it can be used for drug synthesis. my country needs about 2,000 kinds of raw materials and intermediates supporting chemical industry every year, with a demand of more than 2.5 million tons. In the production process of pharmaceutical intermediates, tail gas with complex components will be generated. In order to ensure safe and reliable production, the tail gas needs to be treated.

[0003] The application publication number of the related technology CN213668462U discloses a treatment device for tail gas from pharmaceutical intermediate processing. Through the new tail gas treatment device for pharmaceutical intermediate production, the tail gas is first injected into a de-impurity box for spray treatment to eliminate particulate impurities in the tail gas, and then passed into a drug treatment box for drug liquid treatment. The treatment efficiency is high, and the device has the function of water recycling, thereby improving resource utilization.

[0004] The above equipment uses a new type of tail gas treatment device for the production of pharmaceutical intermediates. The tail gas is first injected into a degassing box for spraying treatment to eliminate particulate impurities in the tail gas, and then passed into a drug treatment box for liquid drug treatment to improve resource utilization. However, after the device has been used for too long, the particulate matter contained in the tail gas will accumulate inside the device, causing the device to operate abnormally and be difficult to clean, thereby causing damage to the device and greatly reducing the service life of the equipment. Utility Model Content

[0005] The purpose of the utility model is to provide a treatment device for tail gas from the processing of pharmaceutical intermediates. The user observes through the visual window whether particles are accumulated inside the device, and then starts the electric push block to drive the push rod and the push block to move. The movement of the push block causes the support rod and the telescopic rod to move in the direction in which the side slide plate is inclined so that the cleaning block can push the particles onto the filter plate. The user can then open the front box door to pull out the filter plate for cleaning, which solves the problem that particulate matter contained in the tail gas of the existing device will accumulate inside the device after the device has been used for too long, causing the device to operate abnormally and be difficult to clean, thereby causing damage to the device and greatly reducing the service life of the equipment.
