Grate type incinerator and treatment process for domestic waste

Abstract

The invention discloses a comb grate incinerator for disposing household refuse and a disposing technology. The comb grate incinerator for disposing household refuse comprises an incinerator body and a dust remover. The incinerator body is provided with an air induction pipeline, a feeding device, an air exhaust pipeline and a discharging device. The air induction pipeline is connected with a hot air source. The top of the incinerator body is provided with the feeding device. A comb wheel is arranged below the feeding device. A comb tooth plate is fixedly connected to the outer circumference of a main shaft. Comb teeth are arranged on the comb tooth plate. The end of the main shaft is connected with a transmission device. A grate bed is arranged on the lower portion inside the incinerator body. The lower portion of the grate bed is divided into a plurality of air inflation chambers. A fan is arranged in each air inflation chamber. The incinerator body on the tail of the grate bed is a cooling pool. The bottom of the cooling pool is provided with same grate plates. The air inflation chamber on the lower portions of the grate plates is connected with a cooling fan. A pushing mechanism is arranged above the grate bed. A plurality of pushing bars are fixed into a frame. The comb grate incinerator is used in cooperation with a cement kiln to dispose municipal solid waste, and is simple in structure, low in building investment, low in running power, low in energy consumption, not prone to damage, easy to maintain, low in running cost, convenient to operate, good in disposing effect, and capable of achieving non-pollution discharge.

Description

technical field [0001] The invention relates to an incinerator, in particular to an incinerator and a treatment process for co-processing urban domestic garbage by using a cement kiln. Background technique [0002] Since the high-temperature gas and alkaline substances produced in the cement production process can eliminate harmful gases such as dioxins produced in the domestic waste incineration process, and the solids after disposal of domestic waste can be used as resources, so the use of cement kilns to co-process urban life Garbage has the advantages of non-polluting discharge and all effective utilization. Due to the complexity of municipal solid waste and the huge differences in physical and chemical properties such as particle size and water content, traditional cement kilns have various methods for co-processing municipal solid waste. This part of the capital investment is relatively large and the operating cost is high, which has become an important reason why it ...
