The working principle is as follows:
the solid processor has the tasks of drying and pyrolyzing the solid wastes, completely burning organic matters in the residues, cooling and discharging. The heat that raw materials conveying mechanism's material stoving utilized comes from the heat that pyrolysis furnace and pyrolysis gas distribute and the heat that the slag burning and cooling produced, will reduce the required energy consumption of follow-up pyrolysis and improve pyrolysis efficiency after reducing the moisture content of material. After the solid processing chamber draws air through the fan, the cavity of the solid processing chamber is in negative pressure, fresh air enters from the slag outlet and then is discharged from the air suction port after the waste heat of the slag, the heat generated by the combustion at the bottom of the pyrolysis furnace and the furnace wall and the heat carried by the pyrolysis gas are all used for drying materials on the raw material conveying belt, and the heat is fully utilized.
The combustor arranged in the heating chamber adjacent to the bottom of the pyrolysis furnace has the function of providing heat required by the pyrolysis furnace by matching with a small part of materials near the bottom of the pyrolysis furnace through oxidation combustion so as to provide heat for the pyrolysis furnace when equipment is cold started or the heat value of the materials is insufficient, a combustion fan arranged in the combustor is responsible for providing combustion-supporting air for the combustor and the combustion of the materials, part of high-temperature smoke generated during the combustion of the materials at the bottom of the combustor and the pyrolysis furnace rises to provide heat for the pyrolysis of the materials in the pyrolysis furnace, and part of the high-temperature smoke can flow out of an outlet at the bottom of the pyrolysis furnace into a cavity of a solid processor. In addition, pyrolysis gas generated by pyrolysis of the material in the pyrolysis furnace flows out from an inlet above the pyrolysis furnace into the cavity of the solid processor.
The slag falling from the bottom outlet of the pyrolysis furnace falls on the slag conveying mechanism and is conveyed outwards, and the heat of the slag is also dissipated in the cavity of the solid processor.
Like this, solid treater inside has accomodate all heats and the gas that material pyrolysis and burning and slag produced, and for preventing that these heat and gas from leaking, the suction opening of establishing provides sufficient air draft volume through the fan and has guaranteed that solid treater is inside to be the negative pressure in order to guarantee that the slag notch only new trend gets into and do not have the intracavity gas outflow.
Because the solid treater must form the intracavity negative pressure and adopted the means of a large amount of convulsions for preventing leaking of heat and inside gas, must lead to a large amount of new trend to mix into the produced combustible gas of pyrolysis, make combustible gas's concentration reduce, because the pyrolysis gas can reach standard after must the abundant burning and discharge, because most burner including hot-blast furnace have certain requirement to gas concentration, if concentration is on the low side can't burn, or need supply a large amount of combustion-supporting fuel and just can cooperate the burning, this will increase the combustion cost. Based on this, the gas burner is set for the combustion of low-concentration combustible gas, and pyrolysis gas and related harmful gas can be completely combusted and discharged after reaching standards under the condition that combustion-supporting fuel is not supplemented or is supplemented less.
The gas burner utilizes the gas heat exchanger that it was equipped with to carry out non-contact's heat transfer mode between low concentration combustible gas and the high temperature flue gas, and the heat of the high temperature flue gas behind the make full use of combustible gas burning promotes the combustible gas's of treating the burning temperature by a wide margin, can realize low concentration combustible gas spontaneous combustion like this under the condition that reduces combustion-supporting fuel, has solved because of carrying out convulsions to the solid treater and has led to the problem that the combustible gas that the pyrolysis produced is difficult to burn after being diluted to a large amount of new trend inhales. The process flow is simplified, and the equipment investment can be reduced.
