Problems solved by technology

The incineration method is simple and effective, but the energy consumption is high, and although the final product of combustion is odorless, it is also a pollutant
The deodorant method and washing method are mainly suitable for the removal of odors with high water concentration and low concentration, and are not suitable for odors with high concentration
At the same time, chemical or biological washing methods also have problems with the disposal of used detergents

Embodiment Construction

[0031] With reference to accompanying drawing, the present invention comprises vortex blower L, it is characterized in that: vortex blower L is connected with biological filter 2 by humidifier 7; Below the filter layer 3 is a gas distribution layer 4, in which there are several air distribution pipes 5 with air distribution holes;

[0032] The filter filler in the above-mentioned air-permeable filter layer 3 adopts activated carbon and earthworm soil stacked alternately. The thickness of the activated carbon layer and the earthworm soil layer is generally 20cm-30cm. Humidifier 7 is connected with the water supply system of breeding house 1 by ball valve 9 .

[0033] The air-permeable filter layer 3 and the gas distribution layer 4 in the above-mentioned biological filter 2 maintain a porosity.

[0034] The ratio of the sum of the cross-sectional area of ​​the above air distribution holes to the inner cross-sectional area of ​​the air distribution pipe 5 is 0.8-1.1.

Abstract

The present invention provides a biological filter deodorization equipment. It includes a blower fan, said blower fan is connected with biological filter by means of humidifier; said biological filter includes air-permeable filter layer whose interior is filled up with filter filler for adsorbing microbe, under the air-permeable filter layer a gas distribution layer is set, in the gas distribution layer several gas distribution tubes with gas distribution holes are set, these air distribution tubes are connected with the above-mentioned humidifier; over the biological filter a gas outlet is set, and between the biological filter and controlled space a gas circulation pipeline is set.

Description

technical field [0001] The invention relates to a biological filtration deodorization device, in particular to a biological filtration deodorization device which adopts a biological filtration method for deodorization. Background technique [0002] The output of meat and poultry eggs in my country ranks first in the world, and China has become a veritable animal husbandry country. However, animal husbandry is still a low-efficiency industry in my country. During the process of transforming feed nutrition into animal products, many ingested nutrients are discharged into the environment without being absorbed, causing huge damage to soil, air, and water sources. pollute. Besides solid manure and sewage pollution, air pollution from farms is another important environmental issue. [0003] The air pollution in livestock and poultry farms mainly comes from the odorous gases emitted from the farms. These gases come from many aspects, such as animal respiration, animal skin, feed...
