Description

Boiler pulse jet soot blower

Technical field

The utility model belongs to boiler safety production and energy-conservation auxiliary device, and what be mainly used in boiler of power plant, station boiler and Industrial Boiler is the impulse soot blowing of medium with the air.

Background technology

In the running of all kinds of boilers, often heating surface is purged slagging scorification, dust stratification and the heated surface corrosion that can prevent boiler preferably, ensure safe operation of the boiler, improve the unit availability, also can improve boiler efficiency simultaneously and reduce the subsidiary engine power consumption.No matter soot blower in the past is traditional steel ball, steam or the vibration and the acoustic systems of exploitation in recent years, owing to be subjected to the limitation of the mechanism of action, energy is single, all can not produce good cleaning effect to the slagging scorification or the viscosity black dirt of boiler heating surface.It is to be power with the combustible gas detonation that pulsing jet blows ash, with the air is the effect media, various energy such as the heat that comprehensive fuel gas detonation is produced, moving, sound, act on boiler heating surface with pulse mode, thereby under identical power consumption its to the cleaning effect of dust stratification greater than other devices, blow grey scarfing cinder effect and improve.But, because existing pulsing jet soot blower overall arrangement is very unreasonable, its jet modulator inside is a whole cavity, the jet transmitter is not established the anti-blocking structure of dust stratification, slagging scorification, so blow ash, the scarfing cinder effect is still undesirable, and is second-rate, fault in service is more, the invalid waste of source of the gas power is big, directly affects the high-quality and high-efficiency operation level of boiler.

Summary of the invention

The purpose of this utility model is exactly technical problem and the deficiency that exists in actual production at existing pulsing jet slag-blowing equipmemt, design provides a kind of boiler pulse jet soot blower of new structure, by redesign, reach and improve boiler thermal output, reduce the boiler energy consumption, guarantee that boiler safety moves, improves the purpose of blowing grey scarfing cinder dirt effect continuously its overall arrangement structure and jet modulator, jet transmitter.

Basic design of the present utility model is, this device comprises that automatic controller, jet initiator, jet cause transfer pipeline, distributor and control cable, divide the two ends of fiery connecting line to be connected with the air inlet pipe of distributor respectively with the jet modulator, the jet of jet transmitter is responsible for the gas outlet of jet modulator affixed, jet transmitter configured in one piece is packed in the boiler body, its jet transmitting tube launch the heating surface of actinal surface to boiler body; The jet modulator structure is: the axis direction along cylindrical shell is packed in air inlet pipe in the cylinder chamber, and cylindrical shell overlaps with the two axial lines of air inlet pipe, on air inlet pipe, be provided with relief hole, the dividing plate and the tubular axis direction that have central through hole vertically are packed in the cylinder chamber, cylinder lumen is separated, the collector ring of bell mouth shape and guide ring symmetry are installed on the dividing plate, and concentric with central through hole, and the bottom of cylindrical shell is provided with the gas outlet; On the jet person in charge diapire of jet transmitting tube, be processed with anti-plug-hole.

This device is flexible configuration as required, the quantity of jet modulator can be equipped with arbitrarily, automatic controller can be controlled single cover system, also can control many cover systems, have blow ash, scaling effect significantly, rapidly, power consumption is low, efficient is high, safe and reliable, installation and characteristics easy and simple to handle, that operation troubles is few, extensibility is strong, is applicable to boilers such as all kinds of different models, the various industry of different structure and power station.

The specific embodiment

Below in conjunction with accompanying drawing the utility model optimum implementation is described in detail.Boiler pulse jet soot blower comprises that automatic controller 1, jet initiator 2, jet cause transfer pipeline 3, distributor 11 and control cable 12, divide the two ends of fiery connecting line 4 to be connected with the air inlet pipe 5 of distributor 11 and jet modulator 6 respectively, and two devices are connected, the jet person in charge 8 of jet transmitter 9 is affixed with the gas outlet 7 of jet modulator 6, jet transmitter 9 configured in one piece are packed in the boiler body 10, its jet transmitting tube 19 launch the heating surface of actinal surface to boiler body 10.Jet modulator 6 structures are: the axis direction along cylindrical shell 13 is packed in air inlet pipe 5 in cylindrical shell 13 chambeies, and cylindrical shell 13 overlaps with the two axial lines of air inlet pipe 5; On air inlet pipe 5, be provided with relief hole 14, the dividing plate 15 that has central through hole 18 vertically is packed in cylindrical shell 13 chambeies with cylindrical shell 13 axis directions, cylindrical shell 13 inner chambers are separated, the collector ring 16 of bell mouth shape and guide ring 17 symmetries are installed on the dividing plate 15, and concentric with central through hole 18, the bottom of cylindrical shell 13 is provided with gas outlet 7.Be processed with anti-plug-hole 20 on 8 diapires being responsible for over against the jet of jet transmitting tube 19.

When removing ash of boiler uses, after a certain amount of fuel gas and air are fully mixed in jet initiator 2 by a certain percentage, along jet cause transfer pipeline 3 with high flow velocities through distributor 11, divide fiery connecting line 4 to enter jet modulator 6, subsequently, automatic controller 1 makes jet initiator 2 fuel gas that ignites, flame front imports jet modulator 6 combustible gas that ignites along the gaseous mixture pipeline into flank speed after distributor 11 is quickened and turned to, form detonation, the high speed and high pressure gas that forms is under the enforce compression of the modulating action of jet modulator 6 and gas outlet 7, the thermal current that quickens enters jet transmitter 9 with certain energy and direction, and at the unexpected cross section formation jet-stream wind of expanding of jet transmitting tube 19 outlets, directly act on generating surface in the boiler body 10, produce the expansion wave beam, purge and wash away surface pipe ash discharge dirt, and various ripples are by reflection, diffraction, characteristics such as transmission act on each physical surface in pipe inner surface of row and the stove, the deep dust stratification of cleaning heating surface, fouling.Cylindrical shell 13 inner chambers of jet modulator 6 are divided into several chambers by dividing plate 15, collector ring 16 and guide ring 17, the combustion mixture that enters cylindrical shell 13 under its effect flows mutual disturbance, form countless vortexs and stream, violent combustion reaction will take place with the speed that is higher than tens of times of smooth combustions in the interior air-flow of each chamber of back that ignites, form detonation, increase substantially pulsing jet ash-removal effect and quality.
