Abstract
The utility model relates to a down-draft type gasifying furnace with a fuel gas filtering function, comprising a gasifying furnace; a raw material inlet, an ash removing hole and a sewage outlet are arranged on the gasifying furnace; the furnace chamber of the gasifying furnace sequentially consists of a drying area, an oxidation area, a reducing area and an ash removing area from top to bottom, wherein the chamber at the drying area is a chamber with a larger upper part and a lower inclined surface; the chamber at the oxidation area is a cylindrical chamber; the reducing area chamber is a chamber with a large middle part and two abdomen-shaped ends; and the chamber at the ash removing area is a conical chamber with large top and small bottom. The down-draft type gasifying furnace has the advantages that the high-temperature fuel gas is blocked by a baffle plate so as to be beneficial to transfer of the heat to the drying area and reinforcement of the drying effect of the raw material, and part of impurities such as water vapor, ashes and the like can be sufficiently separated from the fuel gas by blocking so as to play the primary filtering role; furthermore, the sewage outlet is closed during the running of the down-craft type gasifying furnace, and when the furnace stops running, the sewage outlet can be opened so as to remove the accumulated sewage.
Description
Technical field
The utility model relates to a kind of downdraft vapourizing furnace with combustion gas filtering function, belongs to vapourizing furnace and makes the field.
Background technology
Granted publication CN2677376Y, title " a kind of downdraft vapourizing furnace ", comprise a body of heater, body of heater is made of refractory mortar and thermal insulation layer, the top of body of heater has a feeding device, the bottom has a vapor pipe, be provided with gasifying medium preheating chamber, water vapour generation chamber and catalytic gasification chamber in the body of heater, wherein the gasifying medium preheating chamber is located on the furnace wall of body of heater throat, the top of body of heater inside exhaust pipe is located in the catalytic gasification chamber, and the water vapour generation chamber is located on the furnace wall between gasifying medium preheating chamber and the catalytic gasification chamber.Its weak point: the one, the furnace chamber design is unreasonable, directly influences the effect of aerogenesis; The 2nd, can't carry out filtration treatment effectively to made combustion gas, cause combustion gas impure, the direct contaminate environment of obnoxious flavour that produced in its burning, and be unfavorable for that the user of service's is healthy.
The utility model content
Purpose of design: avoid the weak point in the background technology, design a kind of downdraft vapourizing furnace with combustion gas filtering function.
Design: in order to realize above-mentioned purpose of design.1, adopting the conical design of bore convergent from drying zone to oxidation zone, is one of technical characterictic of the present utility model.The purpose of doing like this is: studies show that the inclination angle is fit to the raw material automatic blanking between 7～10 °, so the vapourizing furnace inclination angle is decided to be 9 °.2, the reduction zone is two of a technical characterictic of the present utility model for the design of " being small at both ends and big in the middle ".The purpose of doing like this is: be beneficial to heat " parcel " in the middle part, reduction zone, prevent " reduction dead angle ", to improve gasification efficiency and secondarily cracking tar.3, oxidation zone adopts the centralized supply wind technology, is three of technical characterictic of the present utility model.The purpose of doing like this is: material is created reduction zone high temperature, anaerobic environment in the concentrated combustion of oxidation zone energy, is beneficial to gasification.4, the design of gas filter is four of a technical characterictic of the present utility model.The purpose of doing like this is: because the combustion gas of vapourizing furnace output contains impurity such as ash content, moisture, tar usually, so the application adopts strainer to filter, and not only removed the impurity in the combustion gas, and the combustion gas after purifying can be satisfied environmental requirement.
Technical scheme: the downdraft vapourizing furnace, it comprises vapourizing furnace, and vapourizing furnace is provided with feed(raw material)inlet, ash disposal mouth, sewage draining exit, and described vapourizing furnace furnace chamber is from top to bottom successively by drying zone, oxidation zone, reduction zone with remove gray area and constitute; Described drying zone cavity is presented big bottom incline chamber; Described oxidation zone cavity is cylinder chamber; That described reduction zone is is broad in the middle, on two tripe shape chamber; Described dedusting area is presented greatly, following conelet face chamber.
The utility model is compared with background technology, and the one, high-temperature fuel gas is through the obstruct of baffle plate, is beneficial to heat on the one hand and is passed to drying zone and strengthens raw material drying, and impurity such as part steam ash content separates from combustion gas through intercepting on the other hand, reaches the primary filter effect; The 2nd, sewage draining exit seals with stifle during operation, during blowing out, is convenient to open the sewage that removing is gathered.
