Description

A kind of waste incinerator of high-temp combustion
Technical field
The utility model is related to a kind of processing unit of solid waste, the waste incinerator of specifically a kind of high-temp combustion, Belong to technical field of garbage disposal equipment.
Background technology
The processing of house refuse is used always in the past based on landfill method, landfill method handle rubbish need to occupy it is a large amount of Land resource, house refuse of high cost, and being landfilled of taking over the land for use, the resolving time is long, will produce during decomposing corruption The waste water and gas of poison pollutes environment.The processing mode of landfill method is gradually replaced by highly efficient burning method in recent years. House refuse is handled using burning method, the volume of solid refuse can be reduced 90% or more, to substantially reduce to soil It occupies.At present burning method processing house refuse equipment generally use waste incinerator, by rubbish put into waste incinerator in into Row burning.
Waste incinerator common configuration design at present on the market is not reasonable, is not enough, causes to the air inlet of burning For hypoxgia when incineration firing, it is susceptible to phenomenon of smouldering, causes ignition temperature too low, when combustion temperature in hearth is less than 850 DEG C When, the pernicious gases such as excessive bioxin are easy tod produce, bring difficulty to the processing of subsequent waste gas purification, it is not easy to reach country It is required that discharge standard.In addition in subsequent waste gas purification processing procedure, the low temperature waste gas relative humidity after spray process It is larger, then bag-type dust is sent to, cloth bag can be caused to moisten blocking rapidly, therefore the exhaust gas after spray process will carry out secondary add After temperature drop low relative humidity, bag-type dust could be carried out.If carried out to exhaust gas using heat caused by waste incinerator Secondary heating, it will help energy efficiency.
Utility model content
The purpose of this utility model is to provide a kind of waste incinerator of high-temp combustion, by the inside for changing incinerator Structure, ensure rubbish in incinerator can high-temp combustion, reduce the generation of pernicious gas, and its fume afterheat can also be utilized To carry out secondary heating to subsequent exhaust-gas treatment.
The specific technical solution that the utility model is taken is as follows:
A kind of waste incinerator of high-temp combustion, upper furnace are flue gas emission area, are incineration firing area in the middle part of burner hearth, Lower furnace portion is ash area;Incineration firing area is from top to bottom divided into multiple burning zones, and each burning zone lower part is provided with fire bars, respectively The fire bars gap of the fire bars of burning zone is successively reduced by upper layer to lower layer;Top layer's burning zone is equipped with rubbish feeding port and for stirring The rubbish stirring mouth that device stretches into;Burning zone is additionally provided with the combustion-supporting benefit temperature for connecting combustion-supporting one of under top layer Mouthful;Each burning zone is equipped with corresponding observation window, and ash area is equipped with ash hole.
The outer wall of the burner hearth is made of steel plate enclosing, and inside outer wall is equipped with one layer of fire clay as inner wall, outer exterior wall Equipped with one layer of heat preservation layer, furnace body is thus constituted;An interlayer is additionally provided between the outer wall and insulating layer in burner hearth incineration firing area Cavity, interlayer cavity are equipped with blast pipe and stretch out outside insulating layer and be connected with air blower, and interlayer cavity is additionally provided with multigroup discharge pipe Road is connected with each burning zone in burner hearth respectively, and every group of air outlet pipeline is equipped with multiple along the evenly arranged outlet air branch of burner hearth sidewall Pipe.The outlet air branch pipe is made of steel pipe, and one end is welded on the steel plate of outer wall and is connected with interlayer cavity, and the other end is worn It crosses inside fire clay and burner hearth and is connected.
The flue gas emission area is separated into upper chamber and lower chambers, the on end lower exhaust of lower chambers middle part by horizontal baffle Pipe, on end upper exhaust pipe in the middle part of upper chamber, the bore of exhaust pipe is small under the relative aperture of upper exhaust pipe, the lower part of lower exhaust pipe and Incineration firing area is connected, and the lower part of upper exhaust pipe is connected with the top of lower exhaust pipe, and the side of upper exhaust pipe connects a water The front end of flat raft tracheae, horizontal exhaust pipe is protruding from burner hearth side, using as main vent, main vent is connected to exhaust gas Cleaning equipment;The top of upper exhaust pipe is set to stretching out except burner hearth top surface using the top as emergent exhaust outlet, emergent exhaust outlet There is openable removable cover;Upper chamber and lower chambers are respectively equipped with exhaust gas entrance and waste gas outlet in the side of burner hearth, above and below Horizontal baffle between two chambers is equipped with upper and lower cavity through hole.
In order to keep the secondary heating of exhaust gas more abundant, the exhaust gas entrance of the upper chamber is positioned close to upper and lower cavity perforation The position in hole, and the sealing plate that one piece is erect is set between upper exhaust tube wall and inboard wall of burner hearth and passes through exhaust gas entrance and upper and lower cavity Through-hole separates, and upper chamber also erects between upper exhaust tube wall and inboard wall of burner hearth multiple not closed wind deflectors;Under described The waste gas outlet of chamber is also disposed at close to the position of upper and lower cavity through hole, and between lower exhaust tube wall and inboard wall of burner hearth The sealing plate that one piece of setting is arranged separates waste gas outlet and upper and lower cavity through hole, and lower chambers are in lower exhaust tube wall and inboard wall of burner hearth Between also erect have multiple not closed wind deflectors;It is achieved in exhaust gas and enters back into cavity of resorption after upper chamber fully stops heating Room, and be then exhausted from after lower chambers fully stop heating.Further, one is additionally provided on the sealing plate of the upper chamber to be used for grasping The movable revolving door that vertical exhaust gas entrance is directly connected to upper and lower cavity through hole, the control handle of movable revolving door protrude outwardly to furnace body top Except face.By the open angle of control handle control activity revolving door, the heating path of exhaust gas can be controlled, and then control exhaust gas The temperature of secondary heating.
The waste incinerator of the utility model is due to reasonable in design, and rubbish is in burner hearth after the screening of multilayer fire bars Each burning zone is automatically fallen by different size to burn, since an interlayer cavity being arranged on the outside of the incineration firing area of burner hearth For even wind, then uniform air inlet is allowed to provide sufficient oxygen through multiple outlet air branch pipes for the burning of each burning zone, to shut out Exhausted phenomenon of smouldering, ensures that all rubbish can be maintained above 850 DEG C of high-temp combustion, and it is harmful to greatly reduce bioxin etc. The generation of gas makes subsequent waste gas purification processing be easy to reach the discharge standard of national requirements.In addition this waste incinerator is logical Flue gas emission area setting exhaust gas heating chamber is crossed, two are carried out to the exhaust gas crossed through spray process using the flue gas heat of waste incineration Secondary heating, contributes to energy efficiency.
