Abstract
The utility model discloses a slag conveying and cooling device of power boiler. A cooling device is arranged in slag water in a cell body of a submersible scraper slag remover, and low-temperature cooling water crosses through the cooling device. Low-temperature water in the cooling device is not directly contacted with the slag water of high temperature in the cell body, and heat of the slag water is transferred to the low-temperature water through the wall surface of the cooling device in order to decrease the temperature of the slag water in the cell body, thereby cooling the slag water and needing no overflow water treatment systems without wasting water resources and polluting environments. Thus the self-cooling spiral slag remover can simplify slag removing systems of boiler, reduce fabrication cost, save on-condition maintenance expense, reduce accommodation area and maintenance working capacity, and improve environmental condition.
Description
Technical field
The utility model is a kind of deslagging device that slag is carried at the bottom of the station boiler that is used for, and belongs to that slag at the bottom of the station boiler is carried, the technical field of cooling device.
Background technology
The big-and-middle-sized pulverized-coal fired boiler in thermal power plant generally adopts immersion type submerged slag conveyor (SSC) to handle and carry end slag, the structure of immersion type submerged slag conveyor (SSC) and forming as depicted in figs. 1 and 2: immersion type drag conveyor 1, cell body 2, transition slag well 3.
Slag at the bottom of the high temperature that falls from boiler furnace through transition slag well, enters the cell body of immersion type submerged slag conveyor (SSC), is full of water in the cell body, and slag after the granulation cooling, is pulled out by the immersion type drag conveyor in cell body at the bottom of the high temperature.
Smooth granulation cooling for slag at the bottom of the normal operation that guarantees immersion type submerged slag conveyor (SSC) and the high temperature; require the pulp water temperature in the cell body unlikely too high; need constantly in cell body, to replenish the lower cooling water of temperature; simultaneously cell body is outwards continuous overflows the higher overflow water of temperature; for the higher overflow water of treatment temperature; outside immersion type submerged slag conveyor (SSC), all be provided with huge and complicated " overflow water treatment system "; be responsible for cooling, clarification and the conveying of overflow water, to avoid water resource to be wasted and contaminated environment.
Summary of the invention
Technical problem: the purpose of this utility model provides a kind of station boiler immersion type submerged slag conveyor that has cooling device, this device guarantee that water resource is not wasted and situation free from environmental pollution under, can cancel the overflow water treatment system that outside immersion type submerged slag conveyor (SSC), is provided with, simplifying boiler removes slag system, reduces cost and saves operating cost, reduce floor space and maintenance workload simultaneously, improve environmental condition.
Technical scheme: the utility model solves the technical scheme that its technical problem adopts and is:
The station boiler immersion type submerged slag conveyor that has cooling device mainly comprises cooling device in immersion type drag conveyor, cell body, transition slag well, the cell body, wherein, cooling device is arranged in the cell body in the cell body, transition slag well is arranged on the top of cell body, the immersion type drag conveyor is arranged on the bottom in the cell body, pass through low-temperature cooling water in cell body in the cooling device, the cooling water inlet of cooling device is connected with the water cooling system of outside with the backwater outlet in the cell body.
Cooling device is positioned at the centre or the side of cell body in the described cell body.Cooling device adopts tubular type or plank frame in the described cell body.
The water that temperature is lower in the cooling device not with cell body in the higher pulp water of temperature directly contact, the heat of pulp water is passed to the lower water of temperature by the cooling device wall, reduce the pulp water temperature in the immersion type submerged slag conveyor cell body, realize the cooling of pulp water, reach the purpose that " overflow water treatment system " need not be set.
Beneficial effect: the utility model is owing to realized self cooling off of immersion type submerged slag conveyor (SSC), cancelled the overflow water treatment system of immersion type submerged slag conveyor, for 2 * 600MW unit boiler, 2,000,000 yuan～5,000,000 yuan, year operation and maintenance costs of can reducing investment outlay reduce 500,000 yuan～1,500,000 yuan; Thereby can reduce station boiler slagging-off system cost and save operation and maintenance cost, reduce floor space and operating maintenance workload simultaneously, improve environmental condition, thoroughly eliminate environmental pollution and the water resource waste that causes by the overflow water treatment system.
