Abstract
The utility model provides a refuse incinerator, comprising an incinerator body, a flue and a blower fan, wherein, a primary combustion chamber is arranged in the incinerator body; a burner is arranged on the primary combustion chamber; the circumference of the inner wall of a hearth of the primary combustion chamber is provided with air ports; the air ports are communicated with a main air pipe at the bottom of the hearth through air branch pipes on the inner wall of the hearth. A secondary combustion chamber is arranged on a fume outlet on the upper part of the hearth; the outlet of the secondary combustion chamber is connected with the flue and a dust remover; the secondary combustion chamber is composed of a combustor and a fuel gas reaction chamber. The utility model can make refuse completely combusted in the process of incineration; the harmful substance in the fuel gas can be efficiently treated again, so that the secondary pollution of combustion tail gas for environment can be decreased; the tail gas accords with the national environmental protection requirement of refuse treatment.
Description
The utility model relates to a kind of refuse treatment plant, particularly a kind of final incinerator of handling of rubbish that is used for.
Resident's house refuse, it is the hard nut to crack that is perplexing the environmentalist that the medical waste of hospital and the industrial refuse of medium-sized and small enterprises are handled always.The whole processing mode of existing rubbish has two kinds basically: 1, rubbish is concentrated buried method, adopt the bigger place of these needs, and early investment is big, and whole treatment effect is bad, is easy to generate secondary pollution after the long-term sealing; 2, burn whole facture, the employing method can obtain treatment effect preferably, at present, widely adopted, but existing incinerator exists following several respects shortcoming: it is many 1, to adopt traditional single BOD air-supply structure, its rubbish to burn in the stove processing procedure residue, and because burning is insufficient, harmful substances a lot of in the rubbish can not be burnt by exhaustive oxidation, and harmful substance and the direct emptying of dust enter atmosphere in the therefore final tail gas, cause the secondary pollution of air; 2, body of heater is originally established the chamber structures that adopt more, and the direct emptying of high-temperature fuel gas that the burning back produces can not effectively utilize its high temperature the harmful substance in the combustion gas is carried out high temperature oxidation process, reduces the relative amount of harmful substance in the combustion gas.
The purpose of this utility model provides a kind of refuse incinerator that can effectively overcome the problems referred to above generation, it makes rubbish sufficient combustion in burning process, and can handle the harmful substance in the combustion gas effectively again, thereby reduce combustion tail gas second environmental pollution.
The purpose of this utility model is achieved in that it comprises body of heater, flue and air blast, it is characterized in that: be provided with the primary zone in the body of heater, which is provided with burner, be provided with the wind hole around its inboard wall of burner hearth, the wind hole communicates with air main at the bottom of the burner hearth by branch wind pipe on the inboard wall of burner hearth; Burner hearth top smoke outlet is provided with secondary combustion chamber, and the outlet of secondary combustion chamber links to each other with deduster with flue, and secondary combustion chamber is made up of burner, combustion gas reaction chamber.
In addition, in order to guarantee that the body of heater cooling water at high temperature produces steam and can in time discharge, avoiding producing pressure brings hidden danger for the burning disposal process, the top of body of heater also is provided with a moisture separator, moisture separator is made up of air inlet pipe, gas-liquid separation chamber and escape pipe three parts, and gas-liquid separation chamber is made of cavity and two staggered water fenders being fixed in the cavity.
The utility model is owing to be equipped with the wind hole around body of heater primary zone burner hearth, so rubbish air feed in the primary combustion process is full and uniform, the oxygen abundance, so the material to be burnt sufficient combustion, residue is few; In addition, the high-temperature fuel gas that primary combustion produces is directly emptying not, but enter secondary combustion chamber between primary zone and deduster and flue, the fuel gas temperature that enters the combustion gas reaction chamber of secondary combustion chamber can be up to the 900-1100 degree, it is burning once more under the effect of last burner, harmful substance wherein can be further by deep oxidation, thereby make directly and to enter in the combustion tail gas of atmosphere by flue that institute contains hazardous substance and dust can meet national atmospheric emission standard, stop the secondary pollution to air, concrete numerical value sees following table for details.
