Concentrated feed waste gas treatment device

Abstract

The invention relates to a concentrated feed waste gas treatment device. The device comprises a gas collecting pipe, an air inlet pipe, a purifying device, an air outlet pipe and an exhaust opening which are arranged in sequence, wherein a booster fan and a treatment chamber are arranged on the air outlet pipe, and the booster fan is positioned above the treatment chamber; the discharge opening of the treatment chamber is provided with a solid outlet and a gas outlet, a waste collection tank is connected with the lower side of the solid outlet, and the gas outlet is connected with a dust collector; the outlet of the dust collector is connected to the air outlet pipe under the treatment chamber; a catalyzing device is arranged in the purifying device, a liquid spray tank is formed in the side of the purifying device and comprises a first spray nozzle connected with the tail end of the air inlet pipe and a second spray nozzle connected to the front end of the air outlet pipe; pressure sensors are arranged on the first and second spray nozzles; sensitive signals of the pressure sensors are conducted to a controller of the liquid spray tank; and the controller is used for controlling start and close and openness of the first and second spray nozzles.

Description

technical field [0001] The invention belongs to the field of concentrated feed processing and relates to a concentrated feed waste gas treatment device. Background technique [0002] Concentrated feed, also known as protein supplement feed, is a compound feed semi-finished product prepared from protein feed (fish meal, bean cake, etc.), mineral feed (bone powder, stone powder, etc.) and additive premix. Adding a certain proportion of energy feed (corn, sorghum, barley, etc.) will become a complete feed that meets the nutritional needs of animals. It has high protein content (generally between 30% and 50%), comprehensive nutrients, and is easy to use. advantage. In recent years, with the development and growth of the industrial manufacturing industry, the development of the field of feed processing has also entered the fast lane. In the production process of concentrated feed, when the amount of fishmeal added is high, it will cause a strong fishy smell in the workshop, whi...
