Abstract
The utility model provides a fuel gas mixing and igniting device. The fuel gas mixing and igniting device comprises an upper end cover, an upper connecting pipe, a mixing chamber, a lower connecting pipe and a connecting flange plate, which are connected in sequence, wherein the mixing chamber is communicated with the upper connecting pipe and the lower connecting pipe respectively; a mixed gas inlet is formed in the upper connecting pipe; flow dividing baffles are arranged in the mixing chamber; an igniter hole is formed in the wall surface of the mixing chamber and is formed below the flow dividing baffles. A mixer and an igniter are integrated, and the position of the igniter and the structure of the mixer are optimized, so that the mixing process and the igniting process of fuel gas, which are completed in sequence, are matched more effectively, the problem of misfire caused after a conventional ash blower is used for a period of time is solved, the mixing capacity is increased, the mixing uniformity is improved, and the igniting success rate is greatly improved.
Description
Technical field
The utility model relates to gas soot blower field, especially a kind of multifunctional fuel mixed firing device.
Background technology
In existing technology because fuel gas mixer and igniter are two respectively different individualities.Due to the distributing cabinet finite volume of distributed system, the volume of blender and igniter is less simultaneously.The gas quantity of internal storage is very little.Will cause like this (combustion gas) gas replenishment process to finish, from gas supply electromagnetic valve is closed to igniting, near the gas concentration in this section of delay time section igniter head may change.Acetylene gas, air melting concn are explosive 15% time, when mixing approaches flammability limit value (2.3%～72.3%), or just there will be miso-fire while going beyond the limit of scope.Occur that this situation is because the reasons such as flue negative pressure is large, air valve is not closed completely, draining valve is not tight cause.These leak sources that are not closed completely can enter air.Air again mixes and can cause gas concentration to decline with the combustion gas mixing.More long more difficult being lighted of time.Can be more difficult if solution goes to have in mind from each leak source.It is not only product quality problem, and the good product of quality also can cause small leak source because of the precipitation of long-time use, foreign material.Also be necessary the time delay of igniting, and this time is generally 0.1～0.5 second.Igniting in the time that if magnetic valve does not fully cut out, the possibility of tempering will increase.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of multifunctional fuel mixed firing device.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of combustion gas mixing igniter, comprise the upper end cover, top tube connector, mixing chamber, bottom tube connector and the mounting flange that connect in turn, mixing chamber is communicated with top tube connector and bottom tube connector respectively, top tube connector is provided with gaseous mixture entrance, in mixing chamber, be provided with distributing damper, igniter hole is arranged on mixing chamber wall, and igniter hole is arranged on distributing damper bottom.The gas flow at this position is comparatively stable.And owing to there being the rear portion of mixed firing device.Change in concentration is later than front portion relatively, is beneficial to and lights a fire successfully.
Further, top tube connector is provided with blast and temperature detection hole.
Further, distributing damper is at least two-layer, interlaced arrangement between the mixed gas outlet of every layer of distributing damper setting.
Advantage and the good effect that the utlity model has are: the utility model is by integrated to blender and igniter, and the position of igniter and the structure of blender are optimized, make the mixing of combustion gas and these two processes that complete in turn of lighting a fire more effectively coordinate, solved soot blower in the past and used the miso-fire producing after a period of time, mixing volume increases, mixture homogeneity improves, ignition success rate significantly improves.Simplify production technology, reduced production cost.

Detailed description of the invention
The utility model provides a kind of combustion gas mixing igniter, comprises the upper end cover 1, top tube connector 2, mixing chamber 5, bottom tube connector 8 and the mounting flange 7 that connect in turn, and mixing chamber 5 is communicated with top tube connector 2 and bottom tube connector 8 respectively.Top tube connector 2 is provided with gaseous mixture entrance 3, be filled with mixing chamber 5 fully mixing again through the preliminary mixed acetylene of last operation and air from gaseous mixture entrance 3, distributing damper 9 by mixing chamber 5 interior settings, to the mobile change of gaseous mixture, makes combustion gas mixing more even.
The interior multilayer distributing damper 9 that arranges of mixing chamber 5, the gas vent of every layer of baffle plate is arranged on the diverse location of distributing damper 9, makes gas flow all need to change direction through every layer of baffle plate, and the mixing of gas is played to facilitation.
Igniter hole 6 is arranged on mixing chamber 5 walls, the bottom of distributing damper 9.Igniter stretches in mixing chamber 5 by igniter hole 6, and lighting a fire to air mixture in the position in air mixture after distributing damper 9 stirs, can farthest make the abundant detonation of combustion gas in mixing chamber 5.
Top tube connector is provided with blast and temperature detection hole 4, can monitor at any time the parameter of deflagration, and the duration of ignition, gas flow and pro rate etc. are regulated.
Empirical tests, applies respective outer side edges air feed equipment of the present utility model, can obtain desirable detonation effect, and miso-fire rate is almost nil.Preferably, the volume of former mixing chamber is: 0.001766m
3, mixing chamber volume is now: 0.003179m
3, volume has increased 0.001314m
3.The volume newly increasing is nearly 0.75 times of original volume.As long as the flow of the liquid leakage current after closed electromagnetic valve is less than 6L per second, just can realize late ignition more than 0.2 second.In actual use, the flow of fluid leakage current is worth much smaller than this.
Above embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variation and improvement etc. of doing according to the utility model scope, within all should still belonging to this patent covering scope.
