Description
Technical field
The utility model relates to a kind of automatic flushing device, specifically a kind of automatic flushing device being used in air preheater heat transfer element, belongs to air preheater service technique field.
Background technology
Air preheater is a kind of heat-exchange device utilizing the smoke exhaust heat of the devices such as boiler, industrial furnace or other power, metallurgy, chemical industry to carry out air required for preheated burning, because it is operated in the lower region of flue-gas temperature, reclaim flue gas heat, reduce exhaust gas temperature, improve the temperature of combustion air, make fuel be easy to catch fire, thus improve the efficiency of the equipment such as boiler, industrial furnace.
Flue gas and air carry out exchange heat by heat transfer element in air preheater, flying dust in flue gas is easily collected in heat transfer element, result in blockage, gas-flow resistance is strengthened, blower fan power consumption increases, and heat-transfer effect reduces, and exhaust gas temperature raises, gas channel can be made time serious to block, affect safe operation.
For keeping the clean of air preheater heat transfer element, usually when the equipment such as boiler are stopped transport, high pressure water washing is carried out to heat transfer element.Generally, the hand-held flushing hydraulic giant of staff, rinses heat transfer element, not only work under bad environment, water under high pressure also easily causes personal injury, and hydraulic giant cannot keep 90 ° of aligning heat transfer elements to rinse by staff simultaneously, reduce flush efficiency, waste water resource.Therefore, empty preheater heat transfer element auto-flushing in the urgent need to.
Summary of the invention
The purpose of this utility model is to provide a kind of device that can carry out auto-flushing to air preheater heat transfer element, can ensure that many nozzles of giant can be aimed at heat transfer element simultaneously and carry out auto-flushing, staff only need operate automatic flushing device and guard outside heat transfer element, thus improve the working environment of staff and ensure personal safety, greatly alleviate workload and increase work efficiency.
For achieving the above object, the technical solution of the utility model is to provide a kind of automatic flushing device, comprise track support, fixed pulley, travel switch, electrical hoist, trolley, giant and switch board, track support there are two channel-section steels as the track of trolley, fixed pulley is fixed on track support one end, electrical hoist is fixed on the other end of track support, travel switch has 2, need to be arranged on respectively two positions of a track support wherein channel-section steel according to stroke, for the stroke of controlled motion dolly, trolley two bottom sides respectively fills two wheels, can freely-movable on the groove steel rail of track support, giant is fixed on trolley top, can move with trolley, giant equidistantly installs 5 ~ 10 nozzles, is threaded connection between nozzle and giant, electrical hoist can rotating, and a rope-out end of steel wire rope is directly connected with one end of trolley, is connected after fixed pulley is then walked around in another rope-out end with the other end of trolley, switch board is placed in easy to operate position, the rotating that can be realized electrical hoist by switch board is controlled, it is characterized in that: track support is placed in immediately below air preheater heat transfer element, when electrical hoist rotates forward, trolley moves right with giant, motion certain distance rear wheel I strikes travel switches I I, then switch board controls electrical hoist reversion, trolley is immediately to left movement, until after wheel II strikes travel switches I, electrical hoist rotates forward, trolley moves right, thus trolley can be moved back and forth on track support between two travel switches, giant moves back and forth along with trolley on track support, and water under high pressure sprays from the nozzle of giant, thus the dust stratification on auto-flushing heat transfer element.
The purpose of this utility model is to provide a kind of automatic flushing device, overcome the deficiencies in the prior art, can ensure that the heat transfer element that many (operating) water nozzles of giant aim at air preheater simultaneously carries out auto-flushing, improve the working environment of staff and ensure personal safety, greatly alleviate workload, improve operating efficiency.
