A support body is fixed at the bottom of the furnace, and longitudinal partition walls are built on the upper of the support body, wherein the side edge of the longitudinal partition walls is closely connected with the inner wall of the furnace body as a whole. Transverse partition walls are arranged between two adjacent longitudinal partition walls and the transverse partition walls adjacent in a vertical direction are left and right intersectedly arranged, and the two adjacent longitudinal partition walls and the transverse partition walls therebetween form a broken line type combustion zone. The zoned combustion type combustion furnace has small land occupation and low cost, the broken line type combustion zone enables zoned combustion of combustible gas, makes combustion more thorough, thereby increasing combustion effect; the furnace wall of the furnace body is provided with a fireproof layer, a heat-insulation layer and a housing made of steel plate, thereby enhancing heat accumulation effect and reducing combustion resistance, wherein the combustion resistance of the combustion furnace is lower than that of the Siemens checker brick combustion furnace by at least 900 Pa; combustible component are burned thoroughly, ash particles of the combustion furnace outlet are greatly reduced, and the erosion to the back boiler system by the air-flow is decreased thereby prolonging the usage life of the boiler system.
Description
Technical field
The utility model relates to the combustion furnace that a kind of waste gas that utilizes caused in chemical fertilizer production burns for raw material, a kind of subregion burning type combustion furnace of more specifically saying so.
Background technology
In the combustion furnace of chemical fields such as fixed bed semiwater gas, owing in burner hearth, be provided with volume internals very big, that mainly constitute by Siemens's checker brick, the useful space of burner hearth is reduced greatly, thereby make the combustible exhaust gas burning not thorough, though there is a kind of outer circulation blowing-out gas combustion furnace to increase the combustion space, but heat storage capacity is very low, and its drawback is: 1, the heat energy recycle rate is lower; 2, combustion furnace is two bodies, and architectural volume is bigger, and cost is higher.
Summary of the invention
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: the subregion burning type that a kind of volume is little, cost is low and combustion efficiency is good combustion furnace is provided.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of subregion burning type combustion furnace, comprise body of heater, body of heater is provided with air inlet, gas outlet and ash port, it is characterized in that: the bottom of furnace body fixed support body, the supporter top is built vertical divider wall by laying bricks or stones, vertically the lateral edges and the inboard wall of furnace body of divider wall closely connect as one, between two adjacent vertical divider walls the lateral isolation wall is set, the upper and lower adjacent lateral isolation wall left and right sides is arranged in a crossed manner, and two adjacent vertical divider walls and the lateral isolation wall between the two form the broken-line type combustion zone.
When described vertical divider wall is whenever built certain altitude by laying bricks or stones, build the lateral isolation wall in the above by laying bricks or stones, every layer of lateral isolation wall area is a bit larger tham half of combustion furnace inner chamber area, to guarantee that air-flow does not take a shorter way, and then on the lateral isolation wall, build vertical divider wall by laying bricks or stones, so alternately build 4～6 layers of lateral isolation wall by laying bricks or stones.
Described supporter is provided with 4～8.Usually according to the combustion furnace diameter, can 4～8 supporters be set at bottom of furnace body, owing to built vertical divider wall by laying bricks or stones on the supporter, therefore vertically divider wall can be divided into 5～9 vertical passages to the inner space of body of heater, the lateral isolation wall is divided into 4～6 layers to the combustion furnace inner space, under the acting in conjunction of vertical divider wall and lateral isolation wall, form 5～9 broken-line type combustion zones, thereby make the flue gas subregion burning that enters from air inlet, improved efficiency of combustion, in addition, repeatedly break-in under the effect of flue gas lateral isolation wall in the broken-line type combustion zone, can strengthen gas molecule motion, improve combustion efficiency greatly.
Described supporter is an arch support body.Supporter can be arranged to multiple shapes such as rectangle, trapezoidal, arch, because domes when being under pressure, can outwards pass to adjacent part to pressure downwards simultaneously, therefore bears other shapes of energy force rate of pressure and is eager to excel, preferably arch support body.
Be equipped with venting on the top of described body of heater and the lower sides.
The furnace wall of described body of heater is provided with three layers from the inside to surface: the shell that flame retardant coating, heat-insulation layer and steel plate are made.Wherein, heat-insulation layer comprises the hard insulating brick of outer field soft insulation quilt and internal layer.Outermost layer is the shell that steel plate is made, and plays a supportive role; Side towards the fire is flame retardant coating (being refractory brick), plays effect fire-resistant, thermal resistance; The centre is hard insulating brick and soft insulation quilt, plays insulation effect, prevents the loss of heat.
The furnace roof profile of body of heater is a truncated cone-shaped or cylindrical.
Operation principle and process:
The utility model only is provided with a combustion furnace body of heater, after waste gas enters body of heater from the upper end air inlet, enter a plurality of broken-line types combustion zone and carry out the subregion burning, and under the effect of lateral isolation wall, repeatedly change the flue gas direction, form more turbulent flow, and, strengthened each molecular motion through repeatedly mixing, separating, improved combustion efficiency greatly, because the flow velocity of design is higher, the flue connection and reasonable arrangement, in the combustion process, the coal particles ratio of combustion is more thorough.In addition, because air-flow is for from top to bottom, and air-flow is carried secretly, separating effect is better,, can not cause in the stove and stop up, form gas and its coal particles of carrying secretly and burnt jointly after the bottom ash port is discharged, and the good situation that can not stop up, excellent working performance.
The beneficial effect that the utility model had is: a kind of subregion burning type combustion furnace is provided, a combustion furnace body of heater only is set, volume and floor space are little, have therefore reduced construction investment, and cost reduces; By a plurality of broken-line types combustion zone is set, make fuel gas subregion burning in stove, combustion process is again the broken line motion, has prolonged burning time, makes burning more thorough, has improved combustion efficiency; The body of heater furnace wall is provided with the shell that flame retardant coating, heat-insulation layer and steel plate are made from the inside to surface, compares with original Siemens checker brick, has strengthened the accumulation of heat effect, and has reduced the burning resistance, and this combustion furnace reduces more than the 900Pa than Siemens's checker brick combustion furnace; Because combustible component burning thoroughly, the dust granule of combustion furnace outlet significantly reduces, and has also weakened air-flow to the washing away of back steam generator system, and has prolonged the service life of steam generator system, makes combustion furnace overall work function admirable.
