[0002] The production of pharmaceutical intermediates involves chemical reactions, which generate a certain amount of waste gas. Therefore, a specialized waste gas treatment system is needed to treat and purify the waste gas before it can be released into the atmosphere. Waste gas purification mainly refers to the treatment of industrial waste gases generated in industrial sites, such as particulate matter, flue gas, odorous gases, and toxic and harmful gases.

[0003] In the prior art, patent document with publication number CN218687884U discloses a waste gas treatment device for pharmaceutical intermediates, including a base plate, a first filter box fixedly installed on one side of the top center position of the base plate, a mounting frame slidably connected between two sliding grooves, a number of fixing plates fixedly installed inside the mounting frame, and a channel can be formed between two fixing plates, and an air inlet pipe penetrating the first filter box and the mounting frame is provided below one side of the first filter box.

[0005] To solve the above-mentioned technical problems, this utility model provides a waste gas treatment device for pharmaceutical intermediate production.

[0006] This utility model discloses a waste gas treatment device for pharmaceutical intermediate production, comprising a base plate, a tank, a No. 1 three-way pipe, a No. 2 three-way pipe, and an exhaust pipe. The tank is mounted on the top of the base plate, and the outer wall of the base plate is connected to the output end of the No. 2 three-way pipe. An exhaust pipe is provided on the top of the tank. The device also includes a filter assembly and a water washing assembly. Two sets of filter assemblies are arranged between the No. 1 and No. 2 three-way pipes, and the water washing assembly is mounted on the base plate. In use, waste gas enters the first set of filter assemblies through the input end of the No. 1 three-way pipe for filtration, and then enters the tank through the No. 2 three-way pipe. The water washing assembly is activated to further clean the waste gas inside the tank. The treated waste gas is then discharged through the exhaust pipe. When it is necessary to clean impurities from the first set of filter assemblies, the two sets of filter assemblies are switched, thereby ensuring continuous waste gas treatment while simultaneously cleaning impurities from the first set of filter assemblies, improving waste gas treatment efficiency.

[0007] Preferably, the filtration assembly includes a gas supply pipe, a filter box, a filter screen, an activated carbon adsorption plate, a cover plate, and valves. The two output ends of the No. 1 three-way pipe are connected to the input ends of one set of gas supply pipes, and the two input ends of the No. 2 three-way pipe are connected to the output ends of one set of gas supply pipes. Each set of gas supply pipes is equipped with a filter box, and each filter box contains a filter screen and an activated carbon adsorption plate. Two sets of valves are installed on the gas supply pipes, with the filter box located between them. The top of the filter box is sealed by a cover plate. Exhaust gas enters the filter box through the No. 1 three-way pipe, where it is adsorbed and filtered by the activated carbon adsorption plate and filter screen, improving impurity treatment efficiency. When the filter screen and activated carbon adsorption plate need to be replaced or cleaned, the corresponding two sets of valves are closed and the corresponding cover plate is removed, improving convenience.

When the delivery pump is started, the solution enters the housing through the suction pipe and the return pipe and is sprayed onto the inside of the tank through the multiple sets of nozzles, thereby washing the exhaust gas entering the tank and improving environmental protection.

[0009] Preferably, the device also includes a disc and permeable holes. The disc is installed inside the tank and has multiple sets of permeable holes. The sprayed liquid falls to the bottom of the tank through the multiple sets of permeable holes, while the exhaust gas rises to the top of the tank through the permeable holes and is discharged through the exhaust pipe. The permeable holes increase the contact time and contact area between the liquid and the exhaust gas, thereby improving the treatment efficiency.

[0010] Preferably, it also includes a drain pipe and a drain valve. The return pipe is equipped with a drain pipe and the drain pipe is installed with a drain valve. When it is necessary to drain the medicine, the drain valve is opened, so that the medicine can be drained through the drain pipe with the cooperation of the delivery pump, thereby improving convenience.
