Description
Technical field
The utility model discloses boiler air preheater and clean device, especially disclose the online high-pressure water flushing device of boiler air preheater.
Background technology
Air preheater is the heat-exchange device utilizing boiler tail flue gas heat to heat the required air of burning, and after denitration SCR system puts into operation, the cold end of air preheater has been equipped with double medium soot blower, uses steam/water under high pressure as sootblowing dielectric, carries out on-line cleaning soot blower.Double medium soot blower it has been equipped with after SCR denitration Retrofit of Air, but, mesohigh water flooding nozzle caliber is big, pressure is low in operation, it is impossible to properly functioning.Further, since spray nozzle clogging, the most not can be removably mounted maintenance, cause immeasurable economic loss, the double medium high pressure water system idleness of equipment of the most in-service unit cannot meet on-line cleaning operation.The high-pressure water pressure of air preheater configuration is generally 20Mpa, can remove ammonium hydrogen sulfate dirt in off-line case, but in on-line case, be affected by high-temperature evaporation and flue gas flow-disturbing, and cleaning performance is had a greatly reduced quality.Additionally, the interior ash gun existence such as pressure-bearing installed of air preheater is inadequate at present, spray nozzle clogging, nozzle drop, rinsed a lot of drawbacks such as dead angle, cause on-line rinsing failure or on-line rinsing weak effect.
Utility model content
This utility model overcomes the deficiency that prior art exists, it is provided that a kind of be not easily blocked, can the online high-pressure water flushing device of boiler air preheater of on-line cleaning.
In order to solve above-mentioned technical problem, the technical solution adopted in the utility model is: the online high-pressure water flushing device of boiler air preheater, including being arranged on flue housing outer end and the support on the cold end sector plate lateral body of fume side rotor bottom, setting up cleaning device on the bracket and the drive mechanism being connected with described cleaning device；Described cleaning device front end is provided with high pressure gun barrel, described high pressure gun barrel is provided with and organizes nozzle more, and nozzle described in least one set comprises two nozzles；Described high pressure gun barrel telescopic moving under the driving of drive mechanism.Using this programme, high pressure gun barrel stretches into inside air preheater under the driving of drive mechanism, and water under high pressure sprays from nozzle through high pressure gun barrel, is carried out air preheater.According to air preheater rotation direction, this device is installed, is arranged on the cold end sector plate lateral body of flue housing outer end and fume side rotor bottom, improve heat accumulating element homogeneous temperature, improve heat accumulating element heat transfer,
The telescopic moving under the driving of drive mechanism of high pressure gun barrel.Putting in during work inside air preheater, off working state all exits air preheater.Therefore, it can on-bne repair under the situation of not blowing out and change accessory.In addition, this utility model changes the mode arranging dust cap in prior art outside nozzle, avoid dust cap serious wear in actual use, the shortcoming that service life is short, this utility model uses rinse-system to stop or during maintenance, and the upset high pressure gun barrel nozzle mode of 180 ° down prevents dust plug nozzle.Secondly, comprise two nozzles by nozzle described in least one set, reduce the probability of spray nozzle clogging, reduce maintenance probability.
Being evenly arranged with four groups of nozzles on described high pressure gun barrel, wherein, three groups outside air preheater comprise two nozzles, remain one group of only one of which nozzle.Arrange nozzle according to rotor size, reach to clean without dead angle.
Employing pressure is 30MPa
Above water under high pressure is as deashing medium.Existing 20MPa can remove ammonium hydrogen sulfate dirt in off-line case, but in on-line case, is affected by high-temperature evaporation and flue gas flow-disturbing, and cleaning performance is had a greatly reduced quality.The water under high pressure using more than 30MPa strengthens cleaning performance.
This utility model compared with prior art has a following beneficial effect:
This utility model changes the mode arranging dust cap in prior art outside nozzle, avoid dust cap serious wear in actual use, the shortcoming that service life is short, this utility model uses rinse-system to stop or during maintenance, and the upset gun barrel nozzle mode of 180 ° down prevents dust plug nozzle.Under off working state, gun barrel all exits air preheater.Secondly, comprise two nozzles by nozzle described in least one set, reduce the probability of spray nozzle clogging, reduce maintenance probability.This utility model is arranged on fanning strip lateral body different from existing installation, simple in construction, heat accumulating element homogeneous temperature, increases heat-transfer effect.

Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, being described in further detail detailed description of the invention of the present utility model, following example are used for illustrating this utility model, but are not limited to scope of the present utility model.
It is illustrated in figure 1 the online high-pressure water flushing device of boiler air preheater, including being arranged on the cleaning device 2 that flue housing outer end with the support 1 on cold end sector plate 4 lateral body of fume side rotor bottom, is erected on support 1 and the drive mechanism 3 being connected with cleaning device 2；Cleaning device 2 front end is provided with high pressure gun barrel 21, and high pressure gun barrel 21 is provided with many group nozzles 211, and least one set nozzle 211 comprises two nozzles；High pressure gun barrel 21 telescopic moving under the driving of drive mechanism 3.
Exemplary, arrange nozzle according to rotor size, high pressure gun barrel 21 is evenly arranged with four groups of nozzles 211, wherein, three groups outside air preheater comprise two nozzles 211, remain one group of only one of which nozzle 211.So arrange can reach clean without dead angle.
