Pharmaceutical waste gas treatment device

Abstract

This application relates to the field of air dust removal, and more particularly to a pharmaceutical waste gas treatment device. It includes a tank, and inside the tank, a rotating shaft, blades, a mesh, a support ring, and an electric motor. The rotating shaft rotates relative to the tank. The blades are fixedly connected to the rotating shaft via a turntable and are fixed inside the support ring. The mesh is fixed within the area formed by the support ring, blades, and turntable. An upper baffle is fixedly connected inside the tank, and water is filled above the upper baffle, flowing downwards onto the mesh. The blades drive external airflow from top to bottom through the mesh, colliding with the wetted mesh to adsorb dust from the air. The dust adhering to the mesh is automatically washed away by gravity, centrifugal force, and airflow. This device is easy to place and reposition in any number at any location, is low-cost, and can achieve automatic cleaning and automatic cooling. Since air does not need to be introduced into the water body during the waste gas treatment process, no bubbles are generated, thus avoiding noise.

Description

Technical Field

[0001] The present application relates to the field of air dust removal, and in particular to a pharmaceutical waste gas treatment device. Background Art

[0002] The auxiliary materials used in the pharmaceutical process usually include starch. Starch is mixed with the drug to make tablets, which is convenient for improving the structural strength and antioxidant properties of the tablets. During the processing, the workshop is usually equipped with a fan for ventilation (used to discharge the air containing starch dust to the outside of the workshop). However, the fan is usually installed at a certain position on the wall of the workshop and can only exhaust locally. Since the workshop is usually large and the exhaust power of the fan is limited, the flow rate of the air in the workshop to the fan is very slow. The exhaust gas source is usually located near the equipment, and the air in various places in the workshop flows slowly and gathers toward the fan. The dust content in the air far away from the equipment is low, and this part of the air accounts for a large proportion of the total air in the workshop, that is, most of the exhausted gas comes from the air far away from the equipment, so the effective work done by the fan on the exhaust near the equipment is relatively low.

[0003] In order to improve the effective work of the fan, several pipes are usually arranged, with the pipe inlet extending near the equipment and the pipe outlet connected to the fan inlet. This allows the fan to use more energy to exhaust the air near the equipment, but after the pipe arrangement is completed, the fan and the pipe cannot usually be easily repositioned. Not all equipment in the workshop works at the same time, and some equipment generates more dust while some generates less dust. Therefore, this fixed-layout exhaust solution still has a lot of ineffective work, and after the exhaust gas is discharged from the workshop, it will form dust near the outside of the workshop, causing pollution to the external air.

The water or solution in the first space passes through the water inlet channel, the first through hole, the second through hole, the cavity, and the third through hole in turn under the action of gravity and centrifugal force and is thrown onto the mesh. The wet mesh absorbs the dust in the air flowing through the mesh, reduces the dust content in the air entering the third space, separates the dust, and achieves a filtering and purification effect. In this process, only one power source is needed, the cost is low, the volume is small, and the water flow and air flow both flow through the inside of the shaft, which can cool the shaft. The air flow also flows through the controller and the electric motor to cool the controller and the electric motor. The dirt on the mesh can be washed away under the action of gravity, centrifugal force, and air flow. It can be seen that the pharmaceutical waste gas treatment device in this embodiment is easy to place and reposition in any number and at any position, has low cost, can achieve automatic cleaning and automatic cooling, and does not need to introduce air into the water body during the waste gas treatment process, so no bubbles will be generated to make noise.
