Abstract
The invention discloses a gasified combustion stove which utilizes gas circulation to realize natural combustion, and pertains to the combustion stoves of various wastes. The gasified combustion stove comprises a stove body composed of a shell and a liner; the top of the upper end of the stove body is provided with an air outlet and a negative-pressure safety valve, the lateral side of the upper end of the stove body is provided with a feeding port; the lower part of the stove body is provided with a traveling grate, the lower part of which is provided with a turn plate for holding materials; the lateral end between the turn plate for holding materials and the traveling grate is provided with an ignition port and an observation window; the lower end of the turn plate for holding materials is provided with a fixed underpan with convex holes; the lower end of the fixed underpan is a bowl-shaped arc underpan with perimeter provided with through holes; the lateral end at the connection of the fixed underpan and the bowl-shaped arc underpan is provided with an ash and dreg discharging port. The gasified combustion stove utilizes the ventilation principle of air pumping at the upper part and natural air supplying at the lower part to realize the full process of aerobic combustion without adding with coal and oil for supporting combustion. The traveling grate and the turn plate for holding materials of the gasified combustion stove can regulate the full process of combustion according to the status of combustion.
Description
Technical field
The present invention relates to the combustion furnace of various refuses, a kind ofly specifically utilize the circulation of gas and realize the gasification combustion furnace of spontaneous firing.
Background technology
The mankind can produce various discarded objects in social activities and daily life, as the discarded object that produces in the industrial production; The discarded object that hospital produces in the treatment patient; Discarded object that people produce in daily life or the like all needs to carry out effective and suitable processing, otherwise not only unhygienic contaminated environment, and directly has influence on the healthy or the like of people.
The method of at present existing many processing defective works, wherein burning is treated to one of method commonly used, as the dedicated combustion furnace of trade waste, the dedicated combustion furnace of Biohazard Waste, the various combustion furnaces of people's domestic refuse.Analyze from above various stoves, ubiquity need carry out combustion-supporting with coal or oil, also therefore, its processing cost height, problems such as emission gases and residue contamination environment are difficult to thoroughly solve or the like.
Summary of the invention
In order to overcome the deficiencies in the prior art, the objective of the invention is to provide a kind of, and utilize the principle of upper and lower ventilation without coal, oily combustion-supporting, realize spontaneous firing, and can cooperate 200810071544.1 and 200820103320.A kind of gasification combustion furnace of the gas emission processing system of X binomial patent applied for.
The technical solution adopted for the present invention to solve the technical problems is: a kind of gasification combustion furnace is characterized in that: by a body of heater of being made up of shell and inner bag, the top, upper end of body of heater is provided with gas outlet and negative pressure relief valve, and the upper end side of body of heater is provided with charging aperture; The lower end of body of heater is provided with travel(l)ing grate; There is the retainer rotating disk lower end of travel(l)ing grate, and the body of heater side between retainer rotating disk and the travel(l)ing grate is provided with lighting-up tuyere and observation window, and the lower end of retainer rotating disk is provided with the fixed underpan with protruding hole, and the lower end of fixed underpan is provided with the bowl-type arcuation chassis of through hole for periphery; The junction side on fixed underpan and bowl-type arcuation chassis is provided with ash discharge, cinder notch.
The other end of described gas outlet is connected with the shredded tobacco for water pipes tower, so that the shredded tobacco for water pipes tower is bled.
The every row of described travel(l)ing grate has the travel(l)ing grate of 1～20 belt length bar tooth, and has 1～8 layer up and down.
Described retainer rotating disk rectangle strip dish is formed by 5～60.
The rectangular bars of described retainer rotating disk is uniform individual layer and upper and lower two layers, and the lower end must touch the surface of fixed underpan.
Described lighting-up tuyere has 1～2.
Described observation window is provided with 1～10 along stove periphery five equilibrium.
When the present invention works discarded object is fed through the upper end of travel(l)ing grate from charging aperture, put into after in a small amount dried firewood is lighted by lighting-up tuyere, the combustion position of seeing according to observation window, during to very hot oven more slowly travel(l)ing grate make discarded object fall into the retainer rotating disk while burning to burn away, wherein ash and the slag after the burning fallen on the fixed underpan, by the rectangular bars of retainer rotating disk it is pushed to ash discharge, cinder notch.Bleeding of shredded tobacco for water pipes tower owing to the body of heater upper end in combustion process makes it produce a kind of through hole nature tonifying Qi by bowl-type arcuation chassis, thereby realizes the overall process that aerobic burns.
The invention has the beneficial effects as follows: bleed in top because the present invention utilizes, the draught principle of bottom nature tonifying Qi, thereby realization need not to add coal, oil carries out combustion-supporting aerobic burning overall process.In addition, travel(l)ing grate of the present invention and retainer rotating disk can be according to the situation overall processes of regulating burning of burning.In addition, negative pressure relief valve of the present invention is located on the furnace roof, closes in the negative pressure course of work, when unexpected power failure or the work of bleeding stop suddenly etc., when temperature raises in the stove, promptly can open automatically, plays the safety effect of protection body of heater.Therefore, the present invention can reach the purpose of drafting.
Description of drawings
Below in conjunction with drawings and Examples the present invention is further described.
Fig. 1 is a topology view of the present invention, and wherein the retainer rotating disk is upper and lower two-layer structure.
