Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to waste gas treatment equipment in a lower auxiliary machine section. Background Art

[0002] Closed rubber mixer is also called internal mixer, which is mainly used for rubber plasticizing and mixing. Internal mixer is a machine with a pair of relatively rotating rotors of specific shapes, which plasticizes and mixes polymer materials intermittently under a closed state with adjustable temperature and pressure. The auxiliary machine under the internal mixer is designed to better play the role of the internal mixer and assist in the processing and handling of materials.

[0003] When the lower auxiliary machine section is in operation, it will generate a certain amount of waste gas. Since the waste gas composition of the lower auxiliary machine section is relatively complex and the concentration is not high, the existing waste gas treatment methods mostly use a dry filter device plus activated carbon adsorption treatment process. However, the waste gas contains oily and sticky particles, which makes the filter device easy to clog, and the heat carried in the waste gas is difficult to effectively reduce, affecting the emission of waste gas. In summary, the existing waste gas treatment equipment still has the following problems:

[0004] The oily and sticky particles in the exhaust gas not only easily lead to the blockage of the activated carbon adsorption layer, but also the heat in the exhaust gas is not well handled. Utility Model Content

At this time, the water in the water tank is extracted by the water pump on the spray purification device and transported to the nozzle on the connecting ring through the connecting pipe. The nozzle sprays the water atomization onto the exhaust gas and performs preliminary filtration through the packing layer, thereby pre-oxidizing the trace oil and smoke in the exhaust gas, reducing the exhaust gas content and VOC concentration in the exhaust gas, and also removing a small amount of particulate matter in the exhaust gas, that is, some substances in the exhaust gas that are easily soluble in water enter the water and are discharged through the sewage outlet. In addition, the spraying method can also effectively cool the exhaust gas to avoid affecting the activated carbon adsorption layer during subsequent exhaust gas filtration.

[0015] 2. After the waste gas is sprayed and purified, the filtered waste gas is transported to the treatment kettle on the disinfection device through the exhaust fan. At this time, the waste gas is irradiated by the ultraviolet lamp in the treatment kettle to sterilize and disinfect the waste gas.
