Introduction of medical waste incinerator

Medical waste is mostly composed of plastic products, glass products and residual drugs, if not treated and abandoned, it is very polluting the living environment, and brings hidden dangers to people's health, medical waste incinerator is a special incinerator of medical waste stove equipment, is a waste treatment machinery. The medical waste incinerator consists of four major systems: waste pretreatment system, incineration system, smoke biochemical dust removal system and gas generator (auxiliary ignition incineration). The medical waste incinerator integrates automatic feeding, screening, drying, incineration, ash removal, dust removal and automatic control. The medical waste incinerator adopts high temperature combustion, secondary oxygenation and automatic discharge of slag, which can meet the monitoring requirements of sewage discharge. In order to enhance the effect of domestic waste incineration, thermal decomposition and gasification (melting) technology are often applied in incineration. The principle of grate incinerator is: the garbage is supplied to the heat-resistant cast iron (steel) grate, and the ventilation is from the lower part of the grate to make the garbage burn. The incineration principle of the fluidized bed incinerator is: ventilation in the porous tube at the bottom of the tower type furnace, so that the sand layer on the flow to form a flow layer, the crushed garbage is put into the furnace and the flow sand (650 ~ 800℃) contact, thus burning instantly, and the ash after combustion is taken to the flue gas treatment system. The incineration principle of the gasification melting furnace is: first, the waste is thermally decomposed into combustible gas and solid residue mainly based on carbon in the reducing gas at 450 ~ 600 ° C, and then burned and melted. In the design of the incinerator, it is necessary to consider the treatment scale of the plant, the nature of the waste to be treated, the mechanical load and heat load of the grate, the heat load of the combustion chamber, the exit temperature of the combustion chamber, the residence time of the flue gas and the heat burn reduction rate.
