Abstract
The invention discloses a kind of method and apparatus of clearing up the boiler tubular preheater.It is removed the dust in the preheater tube by high pressure draught.The equipment of implementing this method is to be made of air compressor, air hose, sebific duct and nozzle, and air hose connects air compressor and sebific duct, and nozzle is inserted in the sebific duct.That the present invention has is easy and simple to handle, cleaning thoroughly, advantage such as labour intensity is little.
Description
The present invention relates to a kind of method for cleaning and equipment that gives hot device dust, more specifically to a kind of method and apparatus of clearing up the boiler tubular preheater,
In order to improve the thermal efficiency of large-sized boiler, generally all within it portion air preheater is set, the air that enters burner hearth is carried out preheating.The preheater that the present invention relates to belongs to tubular type, amounts to 4600 pipes by 4 groups (each 2 groups up and down) and forms.Along with the continuous operation of boiler, the dust that is accumulated in the pipe is on the increase, and makes flue gas normally not discharge, and combustion chamber draft reduces, and it is undesired to burn, and must remove the dust of every pipe this moment, just can make normal operation of boiler.It is a kind of effective how to take, and simple and reliable method for cleaning is that ladies and gentlemen go together for a long time and constantly to explore the problem of seeking to solve.
Before this, the method for cleaning that people adopt has two kinds substantially: a kind of is directly to disclose with reinforcing bar, and the problem that its exists is an operating difficulties, clears up not thoroughly, and pipe is frayed.Its reason is 2.01 meters of preheater pipe ranges, and the distance between two groups is 0.8 meter up and down, and the people can not stand betwixt, and straight reinforcing bar can not be stretched yet, and has only in advance bar bending input pipe inside is stretched again, and the pipe that has can't be disclosed logical at all; Another kind is that preheater is taken apart, discloses with reinforcing bar again, although be easy to cleaning like this, and dismounting inconvenience, time-consuming, labour intensity is big, generally needs 48 hours continuous operation, also has the wear problem of pipe simultaneously.
The present invention is intended to seek a kind of method for cleaning of simple and easy to do, cost-effective boiler tubular preheater, and cleaning equipment easy to utilize a kind of and that this method adapts.
Through long-term practical exploration, find with dust in the high pressure draught cleaning preheater tube simple and effective.Air nozzle is stretched in the pipe, and the air-flow that nozzle penetrates blows dust, and when nozzle blows to pipe during the end, dust together falls.Used air-flow jet velocity is 4～8 meter per seconds.
Adopt the used equipment of this method to form by air compressor, air hose, sebific duct and nozzle, air hose connects air compressor and sebific duct, and nozzle is inserted in the sebific duct, and nozzle chamber is toroidal, the air inlet diameter is 4.5～9 millimeters, and the gas outlet diameter is 8～15 millimeters.
Advantage of the present invention is: easy and simple to handle, cleaning thoroughly, labour intensity is little, the preheater pipe is not almost had wearing and tearing.It is compared with above-mentioned two kinds of methods and can make the boiler continuous operating time prolong 1 times, improves 10 times the service life of preheater pipe, and the deashing work efficiency improves 20 times.
Be most preferred embodiment of the present invention below.
Fig. 1 is the equipment schematic diagram of cleaning boiler tubular preheater.
Fig. 2 is the nozzle cutaway view.
Air hose 2 is connected with sebific duct 3 with air compressor 1, and air hose 2 is one whole, and joint is not established in the centre, and nozzle 4 is contained in the sebific duct 3, and inner chamber is toroidal, and its length is 50 millimeters, and the air inlet diameter is 6 millimeters, and the gas outlet diameter is 10 millimeters.
Select a TV-3/8 air compressor, open in blowing out (banking fire) back, open air valve, when the stagnation pressure before the nozzle was 0.4MPa, the air jet velocity of jet expansion was 6.2 meter per seconds, and the nozzle that sebific duct is related stretches in the blocked preheater tube gradually, dust is blown afloat, stirs by air-spray one by one in the pipe, stretch into the pipe end up to nozzle, dust is all loosening in the pipe, together falls.
Claims (3)
1, a kind of method of clearing up the boiler tubular preheater is characterized in that by high pressure draught, and the dust in the preheater tube is removed, and the jet velocity of used air-flow is 4～8 meter per seconds.
2, a kind of equipment that uses the described cleaning boiler of claim 1 tubular preheater method, by air compressor (1), air hose (2), sebific duct (3) and nozzle (4) are formed, it is characterized in that air hose (2) connects compressor (1) and sebific duct (3), nozzle (4) is inserted in the sebific duct (3).
3, according to the equipment of the described cleaning boiler of claim 2 tubular preheater, it is characterized in that the inner chamber of nozzle (4) is toroidal, the air inlet diameter is 4.5～9 millimeters, the gas outlet diameter is 8～15 millimeters.
