Description

Technical Field

[0001] The utility model relates to the technical field of pharmaceutical waste gas treatment, in particular to an environmentally friendly pharmaceutical waste gas treatment device. Background Art

[0002] In recent years, my country's pharmaceutical industry has developed rapidly and played an important role in the growth of the national economy. Chemical raw materials are the foundation of the pharmaceutical industry, and the production process of the original drug industry will produce waste gas.

[0003] Therefore, it is necessary to install pharmaceutical waste gas purification and treatment equipment in the biopharmaceutical production workshop.

[0004] For example, the pharmaceutical waste gas purification and treatment device disclosed in Chinese patent CN212215039U is designed with a rotatable adsorption box, and the adsorption box is engaged on the rotating shaft. Multiple layers of mesh layers are arranged in the adsorption box, and the adsorption material is laid on each layer of mesh layer, so that multiple layers of different adsorption materials can be arranged in the adsorption box. Since the adsorption box can rotate around the rotating shaft, and the waste gas rises from the bottom layer by layer through different mesh layers and is discharged from the top of the adsorption box, the waste gas and different adsorption materials are fully contacted, thereby ensuring the efficiency of adsorption and sterilization; according to the technical solution provided in the embodiment of the present application, since the bottom of the adsorption box is also provided with a cotton ball adsorbed with sterilizing liquid, it can not only adsorb particulate matter in the waste gas, but also sterilize the waste gas.

[0005] However, the purification treatment device is not provided with a structure for replacing the adsorption material, so it is not convenient to replace the adsorption material after it becomes ineffective after long-term use.

[0006] For this reason, we urgently need to provide a medical waste gas environmental protection treatment device that is easy to disassemble and assemble. Utility Model Content

[0007] The purpose of the utility model is to provide an environmentally friendly treatment device for pharmaceutical waste gas, so as to solve the problem that the purification treatment device proposed in the above background technology has no structure for replacing the adsorption material, so that it is inconvenient to replace the adsorption material after it becomes ineffective after long-term use.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a medical waste gas environmental protection treatment device, comprising a treatment tower and a tower top, the tower top is fixedly connected to the upper end of the treatment tower, an air intake pipe is fixedly connected to the lower right end of the inside of the treatment tower, an exhaust pipe is fixedly connected to the middle position of the top of the tower top, a drain pipe is fixedly connected to the lower left end of the inside of the treatment tower, the inner and outer ends of the treatment tower and the tower top are connected to a treatment mechanism, the treatment mechanism includes a treatment unit and a circulation unit, the treatment unit is arranged inside the treatment tower and the tower top, and the circulation unit is arranged at the right end of the treatment tower.

[0009] The processing unit includes a fixed pipe, a fixed ring, a spray head, an arc plate, a handle, a HEPA filter, an activated carbon filter, a connecting frame, a spring, a clamping plate and a fixed frame. The fixed pipe is fixedly connected to the upper left end of the interior of the processing tower. Valves are arranged inside the air inlet pipe, the exhaust pipe, the drain pipe and the fixed pipe. The fixed ring is fixedly connected to the right end of the fixed pipe. The spray head is fixedly connected to the lower end of the fixed ring at an equidistant distance. The arc plate is connected to the inner front end of the tower top. The handle is fixedly connected to the front middle position of the arc plate. The HEPA filter is fixedly connected to the inner lower end of the arc plate. The activated carbon filter is fixedly connected to the inner upper end of the arc plate. The connecting frame is fixedly connected to the upper end of the front middle position of the arc plate. The spring is fixedly connected to the inner bottom end of the connecting frame. The clamping plate is fixedly connected to the upper end of the spring. The fixing frame is fixedly connected to the front middle position of the tower top.

[0010] A further improvement is that the inner side of the connection frame is slidably connected to the outer side of the card plate, so that when the spring is activated, the card plate can be driven to slide along the inner side of the connection frame, thereby limiting the movement of the card plate.

[0011] A further improvement is that the outer side of the upper end of the card plate is plugged into the inner side of the fixed frame, so that after the upper end of the card plate moves to the inner side of the fixed frame, the card plate and the fixed frame can be relatively fixed.

[0012] A further improvement is that a through slot is provided at the lower front end of the tower top, the outer side of the arc plate is slidably connected to the inner side of the through slot, and the outer sides of the HEPA filter and the activated carbon filter are in contact with the inner side of the tower top. Thus, after the arc plate is slid into the through slot, and the HEPA filter and the activated carbon filter are moved to the inner side of the tower top, the card plate is pushed up by the spring rebound, so that the upper end of the card plate moves to the inner side of the fixed frame, and the arc plate can be fixed to the through slot, and the HEPA filter and the activated carbon filter are fixed to the tower top, so that the exhaust gas discharged from the exhaust pipe will be filtered by the HEPA filter and the activated carbon filter.

[0013] A further improvement is that the circulation unit includes an air pump and a connecting pipe, the air pump is fixedly connected to the upper right end of the interior of the treatment tower, and the connecting pipe is fixedly connected to the right end of the air pump.

[0014] A further improvement is that the end of the connecting pipe away from the air pump is fixedly connected to the lower right end of the inner part of the treatment tower. Thus, when the air pump is started, the waste gas treated by spraying in the treatment tower can be drawn into the connecting pipe and then discharged from the other end of the connecting pipe to the bottom end of the treatment tower to be sprayed again, thereby ensuring that the waste gas in the treatment tower is fully sprayed.

[0015] A further improvement is that a rubber pad is fixedly connected to the outer edge of the HEPA filter and the activated carbon filter. Therefore, after the HEPA filter and the activated carbon filter are fixed to the inner side of the tower top, the rubber pad on the outer side of the HEPA filter and the activated carbon filter contacts the inner side of the tower top, so that the contact between the HEPA filter and the activated carbon filter and the inner side of the tower top can be kept sealed, thereby preventing the exhaust gas after spraying from being completely filtered by the HEPA filter and the activated carbon filter and then discharged from the exhaust pipe.

[0016] In summary, the present application discloses an environmentally friendly treatment device for pharmaceutical waste gas.

[0017] According to the technical solution, after the card plate is pressed down to move it to the inner side of the connecting frame, the handle is pulled forward to pull the arc plate out from the inner side of the through groove. At the same time, the HEPA filter and the activated carbon filter on the inner side of the arc plate will be pulled out from the top of the tower together, so that the HEPA filter and the activated carbon filter can be disassembled for processing when they need to be cleaned or replaced.

[0018] Furthermore, by starting the air pump, the waste gas after spray treatment in the treatment tower can be drawn into the connecting pipe and then discharged from the other end of the connecting pipe to the bottom end of the treatment tower to be sprayed again, thereby ensuring that the waste gas in the treatment tower is fully sprayed.

Therefore, when the spring 609 bounces, it can drive the card plate 610 to slide along the inner side of the connection frame 608, thereby limiting the movement of the card plate 610.

[0029] The fixing frame 611 is fixedly connected to the middle position of the front side of the tower top 2.
