Description
Technical field:
The utility model relates to the equipment of the heat-transfer surface of boiler combustion being implemented ash disposal, relates in particular to a kind of gas distribution device of boiler sootblower.
Background technology:
Boiler is in running, and fouling of heating surface, coking are modal phenomenons, influences the heat transference efficiency of heating surface, weakens the heat exchange between flue gas and working medium, makes the exhaust gas temperature sound pitch, and boiler thermal output reduces.Dust stratification, when coking is serious, just is forced to must blowing out clean, even also has the danger of booster.For convenience remove dust deposit in furnace, coking in time, prior art has adopted multiple ash disposal mode, as steam soaking, compressed air ash disposal, rapping-off-ash and sonic soot cleaning etc.; But all exist not obvious such as dedusting effect, power consumption is high, equipment dependability is poor, the operation and maintenance cost height, the boiler heat-exchange surface is had drawbacks such as infringement.
Generally acknowledge in the prior art that ash disposal mode relatively preferably is the ash disposal of combustion gas high energy pulse, this device produces the blast of combustible gas and air gas mixture energy moment accumulates in the part, the formation high-energy discharges, generation is enough to strong shock wave, sound wave and the heat energy of broken hard dust stratification layer, and the release strength of these energy is controlled, thereby this device can overcome the shortcoming of traditional ash handling equipment, can realize the online ash disposal of not blowing out, can often guarantee each heating surface of boiler not dust stratification or few dust stratification substantially.Similarly pulse soot blower can be referring to Chinese utility model patent specification CN2681828Y.
Above-mentioned combustion gas high energy pulse ash handling equipment is in order to make mist detonation in Impulsive tank, to make the mist volumetric expansion, and then generation high temperature and high speed air-flow, just need the mixed firing device, by the mixed firing device combustion gas and air are mixed with certain proportion, make combustion gas and Air mixing ratio reach explosion limit, and, then flame is carried toward Impulsive tank the mist igniting.The example of this mixed firing device can be referring to Chinese utility model patent specification CN2421531Y.Mixed firing device (especially with the position of air and combustion gas mixing and the position of igniting) in use, owing to will frequently experience high temperature, and each parts of device are many to be made by heat conduction good metal material, and temperature is too high, cooling is bad so be easy to cause.And because in actual the use, the proportioning of combustion gas and air can not reach perfectly the fully required ratio of burning constantly, so imperfect combustion to a certain extent is inevitable, this just causes at the igniting position and position adjacent thereto produces carbon distribution, carbon distribution too much must influence the overall performance of device, even causes potential safety hazard; And in the similar device of prior art,, must thoroughly shut down even will dismantle each pipeline if remove these carbon distributions, open relevant container ... this will be the process that a very loaded down with trivial details effort delays use again.In addition, with the design of the pipeline structure of prior art, if insufficient flow and device pressure everywhere of controlling various air-flows well just very easily causes flue gas to flow backwards, this gently then influences the proportioning ratio of mist, and is heavy then jeopardize safety.
In existing this type of device, be used for the combustion gas distribution portion adopts equal pressure to distribute fuel gas pipeline more, but because it is different with the pressure of boiler connectivity points to be arranged on the mixed firing device of boiler diverse location, in order to guarantee that the mixed proportion of air and combustion gas can be controlled in each road mixed firing device, need adopt acetylene regulator control to the partial pressure of outlet pipe.
The utility model content:
The purpose of this utility model is to carry out the gas distribution device that different pressures distributes at diverse location mixed firing device in the refinement gas distribution device.
The utility model is achieved through the following technical solutions:
A kind of combustion gas distributes cabinet, described combustion gas distributes cabinet to comprise cabinet and inner fuel gas pipeline, it is characterized in that: described gas distribution pipe road comprises air inlet pipeline a, acetylene allocation set case 2, escape pipe in cabinet inside, described gas distribution pipe road is designed to air inlet pipeline a and distributes to 3 same level outlet pipe b1, b2, b3 through acetylene allocation set case 2, described air inlet pipeline a is provided with filter 1, the top of described acetylene allocation set case 2 is equipped with Pressure gauge 5, is respectively equipped with independently acetylene regulator 3 on the described outlet pipe.
Described air inlet pipeline a is arranged on the bottom of cabinet, and described acetylene allocation set case 2 is the thicker tubular body of diameter, and described acetylene allocation set case 2 is erected at cabinet one side, and described outlet pipe b1, b2, b3 are horizontally set on the cabinet middle part.
Acetylene regulator on described outlet pipe b1, b2, the b3 adopts the different pieces of information standard, independent constantly outlet pipe b1, b2, b3 are carried out the pressure adjustment.
Described Pressure gauge 5 is an electro connecting pressure gauge, and described outlet pipe b1, b2, b3 are last between acetylene regulator and allocation set case 2 ball valve 4 is installed.
The utility model is by above technical scheme, realized that compact layout with multitube road delivery of fuel gas is in a cabinet.And output pipe staggers the position each other, easily maintenance and maintenance.On the output fuel gas pipeline of every apportion, according to the position of connected igniter exhaust line different combustion gas is set respectively and joins output pressure, the transporting velocity of combustion gas under the needed explosion strength of the different igniters of accurate Calculation.Reach more at the accurate ash disposal of boiler of Set For Current and reduce the effect of polluting and consuming.
Description of drawings:
Fig. 1 is the structure chart of a kind of better embodiment of the present utility model.
1 filter, 2 acetylene allocation set casees, 3 acetylene regulators, 4 ball valves, 5 electro connecting pressure gauges among the figure;
The specific embodiment:
As shown in Figure 1: be installed in middle part on the air inlet pipeline at cabinet internal ramp 1, the air inlet pipeline level is laid on the bottom of cabinet, cabinet right side in the drawings, vertically the acetylene allocation set case of placing 2 is installed on the sidewall of cabinet, and this mounting means can help the monitoring of gaseous-pressure.Acetylene allocation set case 2 is connected with air inlet pipeline, at the top of acetylene allocation set case 2 electro connecting pressure gauge 5 is installed.The top that in cabinet, is positioned at simultaneously air inlet pipeline install side by side 3 combustion gas outlet pipe b1 b2 b3.Above-mentioned fuel gas pipeline connects 3 cabinets of independently lighting a fire outside respectively after acetylene allocation set case 2 is drawn combustion gas.On three independently combustion gas gas outlet pipeline, be separately installed with acetylene regulator.Three acetylene regulators 3 are arranged on the middle part of cabinet.Use opening and closing of ball valve 4 control fuel gas pipelines on the both sides of acetylene regulator 3.
