Abstract
The utility model discloses a submerged arc furnace exhaust gas waste heat boiler which comprises a boiler barrel, an overheater, a coal economizer, a steel frame, a flue gas inlet device, a flue gas outlet device, a front water-cooled enclosure wall, an intermediate water-cooled partition wall and a rear water-cooled enclosure wall, wherein a front cavity chamber is formed by the front water-cooled enclosure wall and the intermediate water-cooled partition wall; a rear control area chamber is formed by the intermediate water-cooled partition wall and the rear water-cooled enclosure wall; and a full water-cooled enclosure double-chamber structure is formed by the front cavity chamber and the rear control area chamber. The submerged arc furnace exhaust gas waste heat boiler disclosed by the utility model adopts the combined type full water-cooled enclosure double-chamber structure without a horizontal flue, shares one water-cooled partition wall, is large in space, sufficiently utilizes radiating heat, is conductive to utilizing the high-temperature flue, and can be used for effectively solving the problems of ash deposit and coking of a heated surface by being provided with no deposited ash attaching body, thereby enhancing the waste heat utilization rate.
Description
Technical field:
The utility model relates to a kind of high-temperature flue gas waste heat that produces in the industrial silicon mineral hot furnace production process that reclaims, thereby produces the waste heat boiler that steam is used for generating by heat exchange.
Background technology:
The high-temperature flue gas that produces in the product process is taked the miniature boiler that directly emptying the or employing thermal efficiency is lower to existing silicon ore production technology or a small amount of operating cost is high and the unsettled Forced-circulation Waste-heat Boiler of security is utilized, because high-temperature flue gas is emptying obvious waste resource directly, cause the thermal pollution of environment, can not satisfy the requirement that national energy-saving reduces discharging, other measure energy utilization rates are relatively low and cost is higher, and economic benefit is not obvious.
Summary of the invention:
The purpose of this utility model is to provide a kind of mineral hot furnace waste gas residual heat boiler of effective absorption industrial silicon mineral hot furnace high-temp waste gas waste heat.
Technical solution of the present utility model is:
A kind of mineral hot furnace waste gas residual heat boiler, comprise drum, superheater, evaporimeter, water heater, steelframe, gas approach device, exhanst gas outlet device etc., it is characterized in that: also comprise cup water-cooled bag wall, middle water-cooled partition wall, rear chamber water-cooled bag wall, cup water-cooled bag wall and middle water-cooled partition wall form the cavity cup, and middle water-cooled partition wall and rear chamber water-cooled bag wall form chamber behind the tube bank district.
The evaporimeter two ends link to each other with drum by tedge, down-comer.
The inverse u shape double-chamber structure that the full water cooling of chamber composition waste gas residual heat boiler coats behind cavity cup and the tube bank district is without horizontal flue.
The beneficial effects of the utility model:
Ore deposit heating kiln waste gas residual heat boiler adopts the combined type full water cooling to coat double-chamber structure, without horizontal flue, share a water-cooled partition wall, the space is large, take full advantage of radiant heat, be conducive to the utilization of high-temperature flue gas, and without the dust stratification attachment, efficiently solve the difficult problem of fouling of heating surface and coking, improved utilization rate of waste heat.
Description of drawings:
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the configuration diagram of an embodiment of the utility model.
Fig. 2 be Fig. 1 the A-A cutaway view.
Fig. 3 is the top view of Fig. 1.
The specific embodiment:
A kind of mineral hot furnace waste gas residual heat boiler, comprise drum 1, superheater 2, evaporimeter 3, water heater 4, steelframe 5, gas approach device 6, exhanst gas outlet device 7 etc., it is characterized in that: also comprise cup water-cooled bag wall 8, middle water-cooled partition wall 9, rear chamber water-cooled bag wall 10, cup water-cooled bag wall 8 forms cavity cup 11 with middle water-cooled partition wall 9, and middle water-cooled partition wall 9 and rear chamber water-cooled bag wall 10 form chamber 12 behind the tube bank district.
The full water cooling of chamber 12 composition waste gas residual heat boilers coats the inverse u shape double-chamber structure behind cavity cup 11 and the tube bank district, without horizontal flue.
Flue gas flow is the inlet device that high-temperature flue gas enters high temperature resistant accumulatingdust, then the cavity cup that water-cooled bag wall and middle water-cooled partition wall form before and after entering, top by the cavity cup enters rear chamber, tube bank district downwards again, and superheater, evaporimeter, the water heater arranged by chamber behind the tube bank district successively, enter at last the exhanst gas outlet device.
Embodiment recited above only is that preferred embodiment of the present utility model is described; be not that design of the present utility model and scope are limited; under the prerequisite that does not break away from the utility model design concept; common engineers and technicians make the technical solution of the utility model in this area various modification and improvement all should fall into protection domain of the present utility model; technology contents of asking for protection of the present utility model all is documented in the specification requirement book.
