The method of the debirs of China's processing at present mainly includes recycling and reusing and direct incineration method, and incineration method is will to give up Object is heated to l100 DEG C, and the residence time is greater than 2s, so that the organic matter in waste is decomposed into carbon dioxide and water, inorganic matter is with slag Form discharge.Pyrolysismethod is heated to debirs between 700-800 DEG C, and organic matter therein is decomposed reaction, is produced The fuel gas of raw small molecule, while some macromolecular residues (such as tar) are generated,

Debirs are easy to produce the noxious materials such as dioxin during low temperature thermal decomposition, and dioxin is that have to cause There are stringent control in the substance of cancer effect, country, and in order to reduce the dioxin generated in combustion, this paper presents one kind New debirs environment-protection combustion stove has the dioxin etc. generated in debirs combustion process by high temperature second-time burning Noxious material complete decomposition combustion at high temperature.

Application No. is a kind of new energy source energy-saving environment-protection combustion stoves of CN201820424150 patent of invention, Patent No. A kind of improvement structure of environment-protection combustion stove of CN207865440U, notification number are a kind of energy conservation and environmental protection combustion furnace of CN207035087U etc. The structure and performance and the utility model of furnace are entirely different, do not find the relevant data of debirs environment-protection combustion stove.

After still burning at present without discovery debirs, high temperature point is carried out specifically for the toxic pollutant in flue gas Solve, burn and remove the environment-protection combustion stove related data of nitrogen oxides in effluent.

Utility model content

In order to overcome the disadvantages mentioned above of the prior art, the utility model provides a kind of debirs environment-protection combustion stove, can be with It is adapted to include the burning of other organic matters such as livestock of dying of illness, it can be realized the pollutant by debirs in combustion Reheating is carried out, so that the macromolecular Pintsch process in flue gas is burnt, and spray into urea denitrogenation, flue gas realizes harmless discharge, It is simple with structure, easy to operate, the features such as work efficiency is high, safety and environmental protection.

The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of debirs environment-protection combustion stove, packet Sealing furnace body is included, includes debirs combustion chamber in furnace body, debirs combustion chamber is connected by flue with high temperature combustors Logical, high temperature combustors are connected with denitrogenation room, and the denitrogenation room other end is connected with heat exchanger realizes the heat exchange of progress flue gas, Heat exchanger then passes through flue and is connected with cyclone dust collectors, and cyclone dust collectors are connected to bag filter again.

The debirs combustion chamber has been passed through warmed-up air.

The high temperature combustors are further increased on the basis of debirs gas fume of combustion chamber is up to 800-1000 °C Furnace temperature is passed through excessive oxygen, is increased to furnace temperature between 1200-1300 °C using natural gas, diesel oil or pulverized coal as fuel, The noxious materials such as tar and dioxin crack at high temperature and burn into carbon dioxide.

Spray head is provided in the denitrogenation room, spray head sprays urea solution, urea and reaction of nitrogen oxides, generates to big compression ring The harmless nitrogen in border transfers heat to the air into furnace using heat exchanger, makes air inversion required for smoke combustion Warmed-up air is formed by being warming up to 400 °C or so after heat exchanger, flue gas is cooled to 200 °C or so by air inversion Afterwards, into cyclone dust collectors and bag filter.

The heat exchanger, which separately passes through pipeline and is directly connected with debirs combustion chamber and high temperature combustors, leads to organic waste Object combustion chamber and high temperature combustors provide warmed-up air respectively.

The heat exchanger is connected with an air blower, and air blower heat exchanger provides normal temperature air.

The bag filter is connected with spray column；Contain sulfur dioxide in the tail gas being discharged after bag filter dedusting, By spray column spray-absorption, high altitude discharge after the residual exhaust for being discharged out is up to standard.

The beneficial effects of the utility model are: eliminate debirs generates that generate dioxin etc. toxic in combustion The nitrogen oxides that substance and high-temp combustion generate, realizes flue gas harmless emission, is equally readily applicable to include the livestock that dies of illness Etc. the burning of other organic matters, it can be realized the pollutant of debirs in combustion carrying out reheating, make cigarette Macromolecular Pintsch process burning in gas, and urea denitrogenation is sprayed into, flue gas realizes harmless discharge, has structure simple, operation The features such as simplicity, work efficiency is high, safety and environmental protection.
