Atmospheric pressure boiler and method for producing hot water by incinerating sick and dead livestock and poultry and garbage with straw

Abstract

Disclosed are an atmospheric pressure boiler for incinerating livestock and poultry which have died from diseases and waste (8) with straw and producing a hot water, and a method thereof. The atmospheric pressure boiler comprises a boiler foundation (14), a boiler housing (3), a boiler body (4), a boiler wall (32), a furnace hearth (31), a fire grate (30), a combustion system, an air supply apparatus, an air inducing apparatus (13) and a deslagging apparatus (11). The combustion system consists of a burning machine (15), an automatic straw block feeder (1) and a straw fuel block (18). The back portion of the furnace hearth (31) is provided with an incineration door (21) and an incineration pile cap (28). A feeding apparatus (9) for the livestock and poultry which have died from diseases and domestic waste is arranged outside the incineration door (21). A high-temperature flue gas and a hot water of the atmospheric pressure boiler are also connected to a solid thermophilic aerobic fermentation reactor and a liquid thermophilic aerobic fermentation reactor. The atmospheric pressure boiler is further provided with an automatic control system. Harmless, reducing and resource treatments can be applied to organic waste in countryside by using the boiler, thereby protecting the countryside environment and people's health.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to an atmospheric pressure boiler and a method thereof which use straw fuel blocks to incinerate sick and dead animals, livestock and poultry and domestic garbage, and produce hot water. Background technique [0002] When producing organic fertilizers by using the waste from the farming industry (mainly animal manure), in order to provide a suitable breeding environment for aerobic microorganisms, it is necessary to use a boiler to supply hot water and fresh hot air to the aerobic fermentation reactor at the same time. Boilers usually use Coal, electricity and diesel consume scarce and non-renewable fossil energy, which also increases the cost of organic fertilizer production. [0003] On the other hand, in the vast rural areas, the amount of biomass produced by photosynthesis every year is huge. As an energy source, it ranks after coal, oil, and natural...

AI Technical Summary

Problems solved by technology

Improper handling often pollutes drinking water sources and the atmospheric environment, and even unscrupulous traders resell sick and dead animals for huge profits, directly threatening the food safety of ordinary people

At present, the harmless treatment methods for sick and dead pigs are generally high-temperature incineration and sanitary landfill. These measures have problems such as high treatment costs, cumbersome collection and transfer procedures, and inadequate supervision measures; in addition, the secondary pollution caused by the treatment process is also high. very serious

[0007]Due to geographical dispersion and long distances, the cost of collecting and processing domestic waste in rural areas is too high, and it is generally dumped by people at will, causing water and air pollution over time. Pathogen litter can also cause disease transmission
