The holding handles on the gas delivery pipe can be held by hands in the outside of a boiler to make the air pipe extend into the boiler furnace so as to perform the high-pressure sweeping work. The high-pressure gas sweeping apparatus is reasonable in structural design, simple to operate, and easy to use under a high temperature condition.
Description
Technical field
The utility model belongs to boiler furnace Rapid-Repair apparatus field, is specifically related to a kind of boiler furnace Rapid-Repair gases at high pressure clearing apparatus.
Background technology
The boiler furnace Rapid-Repair special equipment that the utility model is related, is mainly used in the mending course after the inner local damage of boiler furnace.Boiler is wear-resisting, after the inner local damage of refractory burner hearth, traditional repairing step is: first blowing out is cooled to below 50 ℃, the secondth, install scaffold, the 3rd is to remove residual lining, weld anchor firmware again, the 4th is the construction of smearing of wearing-proof refractory material, the 5th is that 10 ℃/h heats up at a slow speed, and the 6th is that 30 ℃/h is rapidly heated until serviceability temperature.Existing problems are: generally from blowing out, cool to the complete needs of intensification 96 hours, at 4 days 4 nights, the Maintenance of Boiler time is shortened in the urgent hope of boiler owner to greatest extent.Furnace shutting down process can cause very large economic loss, as 15MW (the about 45t/h of gas making amount) boiler, and blowing out 24 hours, 36000 degree that generate electricity less, by 0.17 yuan/degree electricity, power plant will lose 6.12 ten thousand yuan of incomes from sales.Shorten maintenance time, can reduce the economic loss that boiler owner causes because of maintenance.
The utility model is just to design a kind of for after the appearance infringement of boiler furnace inside, carries out in the process of Rapid-Repair required special high-pressure gas cleaning device under hot conditions.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of boiler furnace Rapid-Repair gases at high pressure clearing apparatus, can realize in boiler Rapid-Repair process the object at cleaning local damage place.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of boiler furnace Rapid-Repair gases at high pressure clearing apparatus is provided, it is characterized in that: comprise airduct, wind hole, fan blade external member, appendix, air valve and grab handle, the more than one wind of array hole on airduct, the sealing of airduct one end, the other end connecting gas transmission pipe of airduct, appendix connects source of the gas; The inner suit of airduct fan blade external member, fan blade external member arranges fan blade more than a slice on edge, and appendix can carry high velocity air to drive fan blade rotation, and fan blade can open and close wind hole by high frequency in rotary course; Grab handle and air valve are set on appendix.
Fan blade and fan blade external member are 90 degree angles, and fan blade is strip, and the outer surface of fan blade is arc surface, offers guiding gutter on inner surface.
Air valve also comprises that valve closes plate, rubber membrane and rubber push rod, offers adjustment hole on appendix, and rubber membrane is set in adjustment hole, and rubber push rod is set on rubber membrane; Valve closes plate and is arranged on appendix inwall, presses rubber push rod and can promote the gas channel that rubber membrane compressing valve closes plate shutoff appendix.
Compared with prior art, the beneficial effects of the utility model are:
1, a boiler furnace Rapid-Repair gases at high pressure clearing apparatus, by the grab handle on hand-held appendix outside boiler, is partly deep into airduct in boiler furnace, carries out operation.Device structure is reasonable in design, simple to operate, is easy to use under hot conditions.
2, gases at high pressure clearing apparatus is offered guiding gutter on Zhi Fengye, gases at high pressure enter after airduct by appendix, by the guiding gutter of offering on fan blade, fan blade is rotated rapidly, make the wind hole of offering on airduct, intermittent opening and closing, realized under the state of lasting gases at high pressure conveying, formed pulsatile effect, the object of carrying out the cleaning of boiler furnace damage surface.
3, in the appendix of gases at high pressure clearing apparatus, air valve is set, be different from the air valve on other equipment, because the requirement of air-flow environment in appendix, when controlling air-flow size, should reduce the obstruction to air-flow as far as possible, guarantee that airduct part is to anticyclonic requirement, so, air valve setting in this device, promotes valve by rubber membrane and closes plate, regulates the size of throughput in appendix.

The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, the utility model is described in further detail.
As shown in Fig. 1, when equipment is used, the grab handle 4 on hand-held appendix 3, is deep into airduct 1 in boiler furnace, by appendix 3, gases at high pressure is transported in airduct 1, from wind hole 2, blows out.As shown in Figure 2, in airduct 1, be provided with fan blade external member 6, in fan blade external member 6, be provided with fan blade 7, on fan blade 7, offer guiding gutter 11 as shown in Figure 5, when air-flow passes through fan blade 7, guiding gutter 11 is because air-flow enters, drive fan blade 7, make whole fan blade external member 6 in the interior rotation of airduct 1, finally make the gas channel in wind hole 2 occur intermittent unlatching, form pulse phenomenon, carry out the cleaning to boiler furnace internal damage position.
As shown in Figure 6, the air valve 5 that equipment is controlled air quantity is arranged in appendix 3, because the requirement of air-flow environment in appendix 3, when controlling air-flow size, should reduce the obstruction to air-flow as far as possible, guarantee that airduct 1 part is to anticyclonic requirement, so, in this device, by rubber membrane push rod 10, control rubber membrane 9, the valve of jack-up down wind closes plate 8, regulates tolerance size.Make whole equipment complete the object at cleaning boiler furnace local damage place.
