Description
Technical field
The utility model relates to a kind of industrial equipment cleaning device, particularly relates to the flexible gun rack device of a kind of desulphurization system air preheater wiper mechanism in service.
Background technology
When the fouling of industry coal-boiler desulphurization system air preheater is serious, because fan operation resistance increases, a large amount of consume electric power, can cause shutdown of boiler when serious stifled ash.Due to its surface scale, cause the heat accumulating element capacity of heat transmission to decline, affect heat exchange efficiency.Adopted in the past stoppage in transit desulphurization system air preheater to carry out the method for manual cleaning, basic solution finished dirty problem, but along with the further raising of Environment Protection Administration requirement and the further in-depth of enterprise's production requirement, the technology that desulphurization system air preheater cleans in running is imperative.
Chinese patent " a kind of industry coal-boiler desulphurization system GGH on-line cleaning system " (patent No. CN201320065264) is exactly a kind of equipment that desulphurization system air preheater cleans in running that is adapted to, this cleaning device is in cleaning process, must under desulphurization system air preheater running status, first jet water gun nozzle be arranged on to the surface of the equipment of being cleaned, and then carry out washing and cleaning operation, the diaphragm seal of installing vertically due to desulphurization system air preheater surface is ceaselessly rotating, if jet water gun nozzle and desulphurization system air preheater surface from too close to, cause diaphragm seal scratch jet water gun nozzle, in order to hide scratch, just jet water gun nozzle must be raised, away from clean surface, so just do not reach best cleaning performance.For the impact of accomplishing not scratched by diaphragm seal, can make again jet water gun nozzle can try one's best near the surface of desulphurization system air preheater, reach optimal cleaning effect, must take effective method more.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned defect of the prior art, a kind of impact that not scratched by diaphragm seal is provided, can make again jet water gun nozzle as far as possible near the surface of desulphurization system air preheater, reach the flexible gun rack device of the desulphurization system air preheater wiper mechanism in service of optimal cleaning effect.
The technical scheme taked is for achieving the above object:
The flexible gun rack device of a kind of desulphurization system air preheater wiper mechanism in service, comprise the body of a gun and jet water gun nozzle, it is characterized in that: the described body of a gun is connected by high-voltage flexible flexible pipe with jet water gun nozzle, described jet water gun nozzle is fixed on portable plate, this portable plate is connected with fixed head by hinge, the body of a gun is arranged on this fixed head, and magnet and back-moving spring are installed on described fixed head, and wherein the other end of back-moving spring is fixed on portable plate.
The flexible gun rack device of desulphurization system air preheater of the present utility model wiper mechanism in service has following technical characterstic:
1, the internal environment that desulphurization system air preheater is in operation is high temperature, high pressure and high humility, and therefore, the resetting system of jet water gun nozzle can not adopt power equipment to drive, and must adopt other method.For this reason, we have adopted " spring+magnet " pattern, the driving force of utilizing elastic force and magnetic force to reset as jet water gun nozzle, the impact that makes cleaning device not scratched by diaphragm seal, can make again jet water gun nozzle can try one's best near the surface of desulphurization system air preheater, reach optimal cleaning effect, the utility model had both ensured the security of operation of equipment, reduce again the volume of mechanism, also precision and difficulty that mechanism manufactures have been reduced, make mechanism simply compact, be convenient to install and safeguard, cost of use is extremely low, in actual production, the cleaning amount that just can be completed by 12 original people is reduced to 3 people, year maintenance cost of a GGH is between 100,000-150,000 yuan (RMB).
2, water under high pressure is delivered to jet water gun nozzle by a high pressure resistant flexible hose by the body of a gun, except rinse water pressure can be increased to 120 Mpa, has also offset the deformation causing due to swinging back and forth of jet water gun nozzle.
3, device of the present utility model, can make desulphurization system air preheater can clean under running status, and it is operated under nominal situation all the time: 1. can reduce the resistance of fan operation, reduce the consumption of electric energy.2. boiler operatiopn is not subject to the impact of desulphurization system air preheater cleaning, avoids the heavy economic losses causing because of blowing out.3. the heat exchange efficiency that increases desulphurization system air preheater, reaches national requirements for environmental protection.The pressure difference of the normal operation of (taking 300MW unit as example) desulphurization system air preheater is in 300Pa left and right, now, and the resistance minimum of blower fan.At present, during generally because of desulphurization system air preheater pressure difference overload alarm (generally in 1200-1500Pa left and right), just consider to shut down to carry out manual cleaning, blower fan resistance is very big, has expended a large amount of electric energy.Install after this device; can be according to the pressure difference of desulphurization system air preheater operation; in non-stop-machine situation, clean (also referred to as cleaning in service), until the pressure difference of desulphurization system air preheater operation drops to normal level, can bring huge economic interests to enterprise.
4, handling safety, easy: saved the huge potential safety hazard that manual cleaning causes, reached the object of safety in production.Time saving and energy saving, improve production efficiency.
In order to assess the cleaning performance of the utility model device, by this device be arranged on the Ningxia #1 of horse lotus throne power plant unit and the #1 of Tongchuan, Shaanxi Province power plant, #2 unit is installed the cleaning performance assessment after this device, flexible gun rack device decapacitation meets outside the ability of tolerance 120MPa pressure jet water, also possesses the frequent ability scratching of tolerance desulphurization system air preheater diaphragm seal, mechanism is safe and reliable, and cleaning has obtained good effect.
