Description

Technical Field

[0001] The utility model relates to the technical field of air deodorization, in particular to a closed environment air circulation deodorization device. Background Art

[0002] At present, air deodorization in closed environments is usually done by extracting odors with exhaust fans and then treating them with deodorizing agents. Existing environments that need to treat odors, such as sludge treatment deodorization and feed treatment deodorization, generally have a relatively low proportion of odor content. Treating odors by spraying a spray liquid containing deodorizing agents and tap water is currently the most common and cost-effective deodorization method.

[0003] Most of the existing spraying equipment directly collects the spraying liquid as waste liquid after using it, and the deodorizing agent in the spraying liquid is often not completely reacted, resulting in not only the waste of deodorizing agent, but also the need to treat the waste liquid of the spraying liquid; and the existing spraying equipment easily takes away the water in the spraying liquid during the exhaust process, and if it is recycled, it needs to be manually replenished with water many times, which is quite troublesome. Therefore, it is necessary to design a deodorizing equipment that can fully utilize the deodorizing agent in the spraying liquid and does not require multiple replenishments. Utility Model Content

[0004] The utility model aims to provide a closed environment air circulation deodorizing device, which solves the problem that the existing closed environment air circulation deodorizing device does not fully utilize the deodorizing agent in the spray liquid.

[0007] Furthermore, the condensation and dehumidification device includes an outlet pipe connected to the outlet and a condenser arranged on the outlet pipe, the condenser pipe includes a heat exchange pipe connected to the outlet pipe and a heat exchange jacket arranged on the heat exchange pipe, and the heat exchange jacket is connected to circulating condensed water for heat exchange.

[0008] Furthermore, the heat exchange tube is evenly provided with a plurality of radially extending condensation columns on the inner wall.

[0009] Furthermore, a plurality of spray heads are arranged at equal intervals at the bottom of the spray box.

[0010] Furthermore, an air distribution plate is provided in the material pool, and the air inlet pipe is connected to the bottom of the air distribution plate.

[0011] Furthermore, the box body is provided with a dosing port for adding deodorant and a water supply pipe for replenishing tap water, and the material pool is provided with a level gauge for measuring the level of the spray liquid, and the box body is provided with a level observation window for observing the scale of the level gauge.
