Abstract

The utility model discloses a device for cleaning the inside of a generator. The device comprises a shockwave generator, wherein a single-control electromagnetic valve is installed on the shockwave generator and connected with a controller; an air inlet end of the shockwave generator is communicated with a high-pressure air tank body; a shockwave spout of the shockwave generator is communicated with a shockwave spraying device through a pipeline; and a spout is mounted on the shockwave spraying device. The device has the benefits that the inside of the generator can be cleaned through multiple actions of shockwave, sound wave and high-speed airflow, thereby achieving a better cleaning effect; the spout and an axis of a rotary nozzle form a certain angle to achieve slant spraying and explosion, and the nozzle is rotated to enlarge the effective soot cleaning scope of a soot cleaning device; the energy consumption of the is low; and the structure is reasonable, and the service life is long.

Description

A kind of generator internal cleaning device

Technical field

The utility model belongs to field of dust, particularly relates to the generator deashing device of a kind of oil field special use.

Background technology

The oil field special wet steam generator is the heavy crude heat extraction key equipment, oil field special wet steam generator convection section finned tube dust stratification directly causes exhaust gas temperature to raise, 10～15 ℃ of the every risings of oil field special wet steam generator cigarette temperature, boiler thermal output descends 1%, behind the each thoroughly deashing of oil field special wet steam generator, general exhaust gas temperature can drop to below 200 ℃, if with residual oil is fuel, boiler cigarette every day temperature rises more than 10 ℃, crude oil is that fuel also should be about 5 ℃, in boiler operatiopn as fuel, atomizing, the air distribution imbalance can cause boiler " over-emitting black exhaust " to aggravate the boiler cigarette temperature rate of climb, boiler convection section deashing generally manually carries out under blowing out cold conditions state, open stove after, the cigarette temperature rises day by day and can't the on-line implement deashing, can cause waste of fuel, oily vapour unit consumption rises.So need a kind of device that can online ash removal.

Present online ash removal device is divided into three kinds, steam dust remover, acoustic wave soot blower and gas shock-wave dust remover.But all there are a lot of problems in use in these three kinds of devices, for example: the major defect of steam dust remover is that Mechanical Reliability is poor, deashing just has a large amount of mechanical parts wearing and tearing after often experiencing a period of time operation, damages, failure mode is generally stuck, bite, the result is not that dust remover can not cause boiler thermal output to descend by bringing normally into operation, and because this type dust remover is to utilize high steam to purge working method continuously, the energy consumption of equipment itself is very big; The problem of acoustic wave soot blower is that power is little, and is very limited to the scavenging action of dust stratification; The gas shock-wave dust remover is a fuel gas because of working media, and the interior cigarette Wen Wendu of each section flue is very high in the boiler, fuel gas enters burner hearth without igniting or flue can cause tempering detonation or cause the bursting of boilers, so can only be used for low-temperature zone, range of application has significant limitation.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of generator internal cleaning device, and this cleaning plant utilizes shock wave, sound wave, high velocity air multiple action that generator inside is cleared up, and ash-removal effect is better, uses safer.

The utility model for achieving the above object, be achieved through the following technical solutions: a kind of generator internal cleaning device, comprise shock wave generator, single control magnetic valve is installed on the shock wave generator, single control magnetic valve is connected with controller, the shock wave generator inlet end is communicated with the pressure-air tank body, and the shock wave spout of shock wave generator is installed spout by pipeline connection shock wave injection apparatus on the shock wave injection apparatus.

Described shock wave injection apparatus is pneumatic stepping rotary nozzle.

Described pipeline is a flexible steel in flat section tubing.

The beneficial effects of the utility model are: can solve the high deficiency that exists in the known technology; Utilize shock wave, sound wave, high velocity air multiple action that generator inside is cleared up, cleaning effect is better; The angled oblique spray of spout and rotary nozzle axis is quick-fried, and the shower nozzle rotation has increased the effective deashing sphere of action of dust remover; And working media is a superheated steam, does not exist the fuel gas pipeline leakage of gas type shock wave dust remover, combustion gas burner hearth to leak potential safety hazards such as bore premature, tempering detonation, excessive gas explosion; Self energy consumption is low; Shower nozzle is short and small, and heavily loaded parts such as no Changqing ash rifle do not have easy-abrasion parts such as mechanical travelling gear yet, more do not have drive motors, are to move pure air-driven type design very reliable; Visit is connected by flexible connecting pipe between shock wave generator, pneumatic stepping rotary nozzle flexibly, can put flexibly according to on-the-spot platform situation, also not can because of boiler expansion to the destructive mechanical stress of device loads; Rational in infrastructure, service life is of a specified duration.
