Description
Technical field
The utility model relates to animal innoxious process for treating field, specifically a kind of animal innoxious burning processing
Flue gas purification system.
Background technique
The flue gas generated in animal burning disposal, present Research, level and the necessity for solving tackling key problem at home and abroad
Property:
(1) present Research both domestic and external, level
Shanghai is the provinces and cities that domestic early start establishes the innoxious centralized processing place of animals died of illness, is begun in 2002
The processing assembly line of equipment based on construction burning process.Originally because domestic not ready-made technology can refer to,
It is substantially built with reference to the technique of consumer waste incineration, but for comparing house refuse with ingredient because of animal harmless treatment amount
Change greatly, it is increasingly complex, therefore gas cleaning processing difficulty with regard to relatively large, with the continuous rising for the treatment of capacity, Shanghai City
Animal harmless treatment center successively carried out overhauling reform, a side to original two sets of animal burning disposals assembly line in 2013
Face advances processing capacity, on the one hand also increases flue-gas cleaning devices again, and incineration flue gas discharge is made to have very big improvement.
After 2013, with the pay attention to day by day that government works to animal harmless treatment, Ministry of Agriculture's pilot promotes dead livestock and poultry harmless
Change processing permanent mechanism working dynamics to reinforce, Shanghai City animal harmless treatment center is arrived successively all to investigate in many brother provinces
Study, Ministry of Agriculture's emergency start has been formulated " animals died of illness innoxious process for treating specification ", in the animal harmless treatment of Shanghai City
The heart, which is mainly responsible for, has drafted burning process partial content.
The ground such as Zhejiang, Jiangsu are relatively large to the Work Promote dynamics of dead livestock and poultry harmless treatment from after 2013, but
With other provinces, which kind for the treatment of process everybody to taking, and more ignorant such as the problems such as He Jianshe centralized processing place, some is borrowed
It is handled with existing consumer waste incineration facility, useless processing equipment processing is cured in some borrows, and some then uses and is applicable in animal material
The processing such as the change preparation method of feature, biological degradation method, sterilization, Hydrolyze method, composting method burial method.It is seldom to the research of burning process
It is related to, even if using burning disposal, the technical treatment that gas cleaning processing is also given up according to house refuse or doctor mostly does not have
Specific aim, and it is unstable.
Developed countries are more early to the harmless treatment work development of dead livestock and poultry, as the U.S., European Union, Canada, day
There are special regulation and technical manual in this grade state to the harmless treatment of dead livestock and poultry, wherein
70% by the way of industrializing burning disposal, therefore, also starts to walk relatively early to the research of its technique, burns heel row
Also relative maturity is reliable for the fume treatment technology put, but still does not get rid of through high chimney emission, big absolutely in the flue gas of discharge
There is also so-called white cigarette phenomenons for majority.
(2) necessity
