Ventilation device for livestock and poultry breeding shed

Abstract

The invention discloses a ventilation device for a livestock and poultry breeding shed, and belongs to the field of livestock and poultry breeding. The device comprises a livestock and poultry breeding shed, wherein the left side of the livestock and poultry breeding shed is provided with a wind guide plate, the right side of the livestock and poultry breeding shed is provided with an exhaust fan,the junction of the exhaust fan and the livestock and poultry breeding shed is provided with a deodorizing device, the livestock and poultry breeding shed at the lateral of the wind guide plate is correspondingly provided with a filter window, the filter window is internally provided with two layers of a screen, and there is hollowed-out filter cotton sandwiched between the two layers. The ventilation device can quickly introduce fresh air into the livestock and poultry breeding shed to remove odor, thereby improving the air quality in the livestock and poultry breeding shed, improving the survival rate of livestock and poultry, and proving a good growth environment for livestock and poultry.

Description

technical field [0001] The invention relates to the field of livestock and poultry breeding, in particular to a ventilation and deodorization device for livestock and poultry breeding sheds. Background technique [0002] China has always been a large livestock and poultry country. With the improvement of people's living standards, the establishment of a balanced diet concept and the continuous growth of the population base, my country's consumption of meat food has been in a period of vigorous growth. Large-scale livestock and poultry breeding has stimulated the livestock and poultry breeding industry The prosperity and development of the livestock and poultry industry, but with the rapid development of the livestock and poultry industry and intensive breeding, the phenomenon of concentrated livestock and poultry breeding produces a lot of stench and pollutes the air environment is becoming more and more serious.

[0002] China has always been a large livestock and poultry country. With the improvement of people's living standards, the establishment of a balanced diet concept and the continuous growth of the population base, my country's consumption of meat food has been in a period of vigorous growth. Large-scale livestock and poultry breeding has stimulated the livestock and poultry breeding industry The prosperity and development of the livestock and poultry industry, but with the rapid development of the livestock and poultry industry and intensive breeding, the phenomenon of concentrated livestock and poultry breeding produces a lot of stench and pollutes the air environment is becoming more and more serious. In the existing livestock and poultry breeding production, the air quality is relatively poor , there is an abnormal smell. In order to adapt to the social and economic development and industrial development direction, and to solve the environmental pollution problem, it is necessary to develop a ventilation and deodorization device for livestock and poultry ecological breeding. At present, the primary problem to be solved in livestock and poultry farming is to Bad smell treatment

[0003] The odor produced by livestock and poultry breeding has complex odor components, mainly chemical substances such as ammonia, sulfur compounds, amines and some low-level fatty acids. At present, most domestic farms still use traditional deodorization methods, such as ventilation, spraying, etc. etc. Existing deodorization technologies include adsorption method, deodorant method, thermal oxidation method, washing method, biological filtration method and oxygen ion group deodorization method. Deodorization, suitable for the treatment of high- and medium-concentration malodorous substances, can handle large-flow gases, the process is the most mature, but the purification efficiency is not high, the absorbent is consumed, and the pollutants are only transferred from the gas phase to the liquid phase; thermal oxidation method, using The method of deodorizing odorous substances by oxidation of oxidants, this method is suitable for the treatment of low-concentration malodorous substances, with high purification efficiency, but requires oxidants, and the treatment cost is high; washing method, secondary pollutants may be formed during the treatment process; biological filtration Deodorization method and oxygen ion group deodorization method. These two methods mainly use microorganisms to degrade odorous substances to deodorize. The deodorization efficiency is high, the deodorization device is simple, the treatment cost is low, the operation and maintenance are easy, and secondary pollution can be avoided, but pollution cannot be recycled. thing
