Description

Technical Field

[0001] The utility model relates to the technical field of air treatment, in particular to a deodorant dosing device at an air outlet of a paper machine. Background Art

[0002] During the papermaking process, the gases generated during the dehydration and drying of paper are collected and discharged to the outside atmosphere through exhaust fans, which will cause odor in the surrounding environment and affect the surrounding living environment. Therefore, further improvements need to be made on this basis to reduce the odor of atmospheric emissions. Biological deodorizer is the most common and mature process used in atmospheric treatment. The main principle is to use acid, alkali, water, and oxidant to absorb the alkali, acid, water-soluble, and oxidizable substances in the exhaust gas. Adding biological deodorizer can effectively reduce the odor of atmospheric emissions;

[0003] For example, the utility model announcement number CN215463398U is an automatic dilution and dosing device for a passivation deodorant, comprising a frame, on which a liquid medicine tank, a metering pump, a mixing box and a cleaning pump are arranged, the liquid medicine tank and the cleaning pump are arranged on both sides of the mixing box respectively, the liquid medicine tank is connected to the mixing box through the metering pump, a stirring device is arranged inside the mixing box, the top is connected to the liquid outlet of a three-way solenoid valve through a first liquid inlet pipe, a separation device is arranged on the top of the side wall, one liquid inlet of the three-way solenoid valve is connected to a clean water pipe, the other liquid inlet is connected to a reflux pipe, and the liquid inlet pipe of the cleaning pump is arranged inside the mixing box.
