Abstract
The utility model discloses a dry cooling deslagging device. System equipment having the functions of a dry deslagging system is reformed from the existing wet deslagging system equipment by changingthe existing wet deslagging process into a dry deslagging process, so the system equipment has all properties of a mature dry deslagging system. The dry cooling deslagging device consist of parts of the equipment of the wet deslagging system: a water seal channel, a slag well, a shutoff door and a boiler, and equipment necessary to a dry deslagging system: a sealed type expansion joint and a dry deslagging device. Through the reformation above, a wet deslagging process using water for cooling hot slags is changed into a dry deslagging process directly cooling hot slags with ambient air withoutmaking any change on the boiler. In the way, on one hand, the purpose of improving boiler efficiency is achieved; on the other hand, the purposes of discharging wastes and reducing equipment examination, repair, operation and maintenance costs are achieved on the premise of improving the comprehensive utilization rate of slags. The device has considerable economic and social benefits.
Description
Technical field
The utility model relates to coal-fired station's furnace bottom warm sludge cooling device, and is specifically a kind of by dry type cooling slag-draining device.
Background technology
At present, wet type slagging-off mode is adopted in China overwhelming majority's thermal power plant, and promptly the high temperature furnace slag in the burner hearth utilizes water at low temperature to cool off, and slag is discharged with the wet slag form of band moisture content then, and the wet slag comprehensive utilization ratio is very low.This class warm sludge type of cooling, water consumption is big, and treatment facility is many, and expenses such as sewage disposal device operation, maintenance are big, bring pollution to environment.In recent years, along with the development of dried slag removing technology, the new thermal power plant of building has been adopted the direct cooling down high-temperature slag of air mode, i.e. dried slag removing system mostly.The slag that adopts the dried slag removing system to discharge is dried slag, and the active component of slag does not have destroyed, the comprehensive utilization ratio height.The dried slag removing technology is a cover mature technique, and it is quite obvious in advantage energy-conservation, that economize on water, save land, reduce aspects such as pollutant emission, raising boiler combustion efficiency.Wet type is removed slag system and is compared with the dried slag removing system, and its working mechanism, system equipment structure all have bigger difference.If it is a whole set of wet type slagging-off system equipment all is replaced by the dry-type slag extractor system equipment, very expensive.Therefore, if being removed slag system, existing a large amount of wet types change the dried slag removing system into, its economic benefit, obvious social benefit.The slag-draining device of dry type cooling at present can't utilize wet type slagging-off system equipment to reequip.
The utility model content
The purpose of this utility model is for solving above-mentioned existing problems, a kind of dry type cooling slag-draining device that provides.
A kind of dry type cooling of the utility model slag-draining device, remove a part of equipment of slag system by wet type: water sealed tank (1), slag well (2), shutoff door (3), the essential equipment of boiler (6) and dried slag removing system: sealed expansion joint (4), dry-type slag extractor (5) equipment constitutes, there is overfall (9) in described slag well (2) outside, increase grid (8) at dry-type slag extractor (5) discharge gate position, dry-type slag extractor (5) stainless steel conveyer belt drives, water sealed tank (1) is the connector between boiler (6) and the slag well (2), slag well (2) is mounted in the hopper on dry-type slag extractor (5) top, shutoff door (3) is installed on slag well (2) outlet, sealed expansion joint (4) is arranged between dry-type slag extractor (5) and the slag well (2), around the shutoff door (3), dry-type slag extractor (5) is made up of warm sludge cooling and conveying equipment.Described dry type cooling slag-draining device is removed the warm sludge cooling water water system that wet type is removed slag system, only keeps a small amount of boiler water seal water.Remove whole sewage disposal system equipment, keep wet type and remove slag well, the shutoff door equipment of slag system, the scraper-type wet type dragveyer of loop chain transmission change into the stainless steel conveyer belt drive, by the conveyer belt carrying and finish the dry-type slag extractor of warm sludge cooling procedure, utilize surrounding air that warm sludge is directly cooled off.Wet type slagging-off system equipment Open architecture, all sealings.Equipment links to each other with the expansion joint of equipment room by sealing, except necessary cooling air inlet, after armamentarium links to each other, forms the closed conveying space, ashless and hot-air ejection.
This patent by existing wet type slagging-off system equipment is transformed, changes original wet type deslagging process into dried slag removing technology exactly, makes system equipment have the function of dried slag removing system, thereby reaches the over-all properties that ripe dried slag removing system is had.By above-mentioned transformation, boiler is not being done under the situation of any change, the wet type deslagging process that utilizes water to carry out the warm sludge cooling is changed into the dry slag disposal technology of directly cooling off by surrounding air.Like this, reached the purpose that improves boiler efficiency on the one hand, on the other hand, can reach energy-conservation, economize on water, reduce pollutant emission, reduced the purpose of overhaul of the equipments, operation and maintenance cost, simultaneously, the comprehensive utilization ratio of slag is improved.Have considerable economic and social benefit.
Description of drawings
Fig. 1 is a kind of dry type cooling of the utility model slag-draining device structure chart.
Among the figure: the 1st, water sealed tank, the 2nd, slag well, the 3rd, shutoff door, the 4th, sealed expansion joint, the 5th, dry-type slag extractor, the 6th, boiler, the 7th, sealing water, the 8th, grid, the 9th, overfall.
The specific embodiment
The utility model is by a part of equipment of wet type except that slag system, i.e. water sealed tank (1), slag well (2), shutoff door (3); And the essential equipment of dried slag removing system, promptly sealed expansion joint (4), dry-type slag extractor equipment such as (5) constitute.Specifically,
Water sealed tank (1): water sealed tank (1) is the connector between boiler (6) and the slag well (2), and it plays boiler (6) expansion, the effect to sealing between boiler (6) and the slag well (2) of absorbing.Wet type is removed in the slag system, and sealing water (7) is constantly to the inboard overflow of slag well (2), and water mixes with warm sludge, and participates in the warm sludge cooling.And in the dried slag removing system, sealing water (7) changes into to overfall (9) overflow of slag well (2) outside, only plays the effect that boiler (6) expands, boiler (6) is sealed that absorbs.
