Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of dust recovery, and specifically relates to a dust suppression and recovery device for chemical synthesis. Background Technique
[0002] The dust generated during the chemical synthesis process mainly refers to the fine particles splashed out from equipment such as reaction kettles, pipelines, valves, pumps, etc. These particles will float in the air to form a dust cloud, which poses hazards to human health and the environment.
[0003] The dust generated during the chemical synthesis process mainly includes the following types:
[0004] Silica is one of the basic raw materials used in many synthesis processes, such as silicates, glass, ceramics, etc. These synthesis processes may all generate silica dust.
[0005] Metal oxides are important components of many catalysts, coatings and pigments, such as titanium dioxide, alumina, etc. These synthesis processes may all generate corresponding metal oxide dust.
[0006] Polymers are high molecular compounds, such as plastics, rubbers, etc. Polymer dust may also be generated during the synthesis process.
[0007] For the dust generated by chemical synthesis, most of the existing equipment sucks the dust through a dust suction device, and then filters the air containing dust through a filter cloth or an air filter element. After filtration, the dust is recovered. The particle size of the dust is too small and it is easy to pass through the air filter element or the filter cloth, and is discharged into the air, resulting in dust loss and causing secondary pollution to the ambient air. The long-term use of the air filter element or the filter cloth will cause blockage, reduce the filtering effect, and increase the filtering energy consumption. Therefore, a dust suppression and recovery device for chemical synthesis is needed to improve the above problems. Content of the Utility Model

[0011] Note: By separating dust from air through scrubbing, the humidity of the discharged air can be increased.
[0012] Further, the filtering device includes a filtering box, a filtering rack is arranged inside the filtering box, a collection box is placed on the filtering rack, a reflux pump is fixedly connected to the bottom of the filtering box, the water outlet of the reflux pump is fixedly communicated with a reflux pipe, and the other end of the reflux pipe is fixedly communicated with the top of the scrubbing box.
