Small-sized three-dimensional garbage incinerator with combustion chambers

Abstract

The invention discloses a small-sized three-dimensional garbage incinerator with combustion chambers. The periphery of a first combustion chamber is used as a second combustion chamber, so that heat loss of the first combustion chamber is avoided, and the pyrolysis temperature of the first combustion chamber can be increased; the periphery of the second combustion chamber is used as a combustion air preheating layer, so that heat loss of the second combustion chamber is avoided, meanwhile, combustion air is heated, and combustion supporting and temperature rise of the first combustion chamberand the second combustion chamber are facilitated; high-temperature flue gas from the second combustion chamber passes through an air cooling heat exchanger, the combustion air is heated by the heat exchanger, so that part of heat in the flue gas is replaced, and the flue gas enters the air preheating layer, the first combustion chamber and the second combustion chamber in the tangential directionrespectively; heat generated by garbage incineration is conveyed back into the incinerator to the maximum extent, so that the heat in the first combustion chamber and the second combustion chamber isaccumulated continuously, the first combustion chamber and the second combustion chamber do not need combustion supporting any more, and stable operation can be realized; and therefore, energy is saved, and the operating cost is reduced.

Description

technical field [0001] The invention relates to the technical field related to incinerators, in particular to a small three-dimensional combustion chamber garbage (medical life) incinerator. Background technique [0002] Usually design and produce small (medical / domestic) waste incinerators, which are divided into a combustion chamber and a second combustion chamber. First put small (medical / domestic) garbage into a combustion chamber, and use fuel oil or natural gas to support combustion and let in air to make the garbage pyrolyze and gasify. Usually, the pyrolysis temperature is not lower than 850°C. The flue gas produced by pyrolysis contains a large amount of combustibles such as organic waste gas, but the concentration of combustibles in the flue gas usually does not reach the spontaneous combustion concentration. The flue gas is introduced into the second combustion chamber of another equipment, and the combustibles in the flue gas are completely burned and decomposed...
