Description
Technical field
The present invention relates to a kind of cleaning gun, especially the special-purpose cleaning gun of tubulation.
Background technology
In the glycol unit production process, key reaction be ethene and oxygen under the silver catalyst effect, generate oxirane in fixed bed reactors generation oxidation reaction, simultaneously by-product carbon dioxide and water.Ethylene oxide reactor is the fixed-bed type shell-and-tube reactor, and the distribution tubulation is 13500 in the bed, and the tubulation internal diameter is 21mm, and pipe range 7.7m is at the inner silver catalyst of installing of tubulation.The catalyst that device adopts was generally 3 years service life, and reactor tubulation material is a carbon steel material.
Can there be a certain amount of iron rust in carrying out along with producing in the reactor tubulation, and the existence of iron rust generates oxirane to the ethene oxidation and produces more significantly influence: on the one hand, the carrying out of aggravation side reaction reduces selectivity; Free iron ion catalytic epoxyethane isomery generates aldehyde material in the iron rust on the other hand, to product yield and product quality deleterious impact all.
The device general using more chance of catalyst changeout eliminates rust to the reactor tubulation.Traditional method is to adopt the sanding derusting process, produces needs but this technology often is difficult to satisfy device, and the sanding rust cleaning causes the excessive wear at tubulation mouth of pipe place easily on the one hand; And the rust cleaning effect of tubulation middle part and bottom is not ideal enough; Because the agitated reactor space is narrow and small, make traditional rust cleaning work be difficult to operation simultaneously on the other hand, influence the duration.
Adopt the steel wire lump derusting method; Steel wire lump motion from top to bottom in the reactor tubulation under gas promotes, in the double action of frictional resistance and upper gas pressure, steel wire lump is radially expanded; Increased frictional property with tube wall; Reached evenly rust cleaning from top to bottom, accomplished that tubulation bottom rust cleaning effect does not reduce, and has guaranteed the effect of rust cleaning.Simultaneously, adopting the steel wire lump rust cleaning little to the damage that the reactor tubulation causes, is a kind of better tools for cleaning rust.
Use steel wire lump rust cleaning though it is effective to eliminate rust, needs to make a kind of convenience special-purpose cleaning gun of tubulation efficiently, steel wire lump is eliminated rust in the reactor tubulation and cleans by the special-purpose cleaning gun of tubulation.
Summary of the invention
The present invention manufactures and designs a kind of cleaning gun, and this cleaning gun is exclusively used in tubulation, and preferably this cleaning gun is exclusively used in the ethylene oxide reactor tubulation.For preventing that the secondary iron rust from polluting, this cleaning gun adopts the stainless steel material manufacturing.This cleaning gun top has handrail, source of the gas tube connector interface, and the middle part has the control ball valve, ball valve rear portion setting pressure table, and the bottom has pedal, and pedal is exerted pressure to rubber stopper, reaches the sealing of rifle head and tubulation.This ball valve is used for source of the gas control, and this Pressure gauge is used to observe duty, changes through pressure and can judge whether steel wire lump or sponge ball are released the reactor tubulation smoothly.
The invention still further relates to a kind of method of using cleaning gun rust cleaning, during use source of the gas tube connector interface connection work source of the gas, with steel wire lump or sponge bulb stopper in tubulation; The rifle head and the tubulation mouth of pipe that connect cleaning gun; Exerting pressure through pedal reaches the sealing function at rifle head and tubulation mouth of pipe place, opens ball valve connection work source of the gas, observes Pressure gauge;, pressure descends suddenly after rising earlier; Just can judge that steel wire lump or sponge ball released tubulation smoothly, the work source of the gas of utilization purges and can iron rust residual in the tubulation be blown out several seconds, accomplishes the rust cleaning of this tubulation.This work source of the gas is a 0.7MPa compressed air.

Wherein, 1-cleaning gun, 2-handrail, 3-source of the gas tube connector interface, 4-ball valve, 5-Pressure gauge, 6-pedal, 7-rubber stopper, 8-rifle head.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further specified:
Fig. 1 shows cleaning gun 1, and this cleaning gun 1 is exclusively used in tubulation, and preferably this cleaning gun is exclusively used in the ethylene oxide reactor tubulation.For preventing that the secondary iron rust from polluting, this cleaning gun 1 adopts the stainless steel material manufacturing.This cleaning gun 1 top has handrail 2, source of the gas tube connector interface 3, and the middle part has control ball valve 4, ball valve 4 rear portion setting pressure tables 5, and the bottom has pedal 6, uses pedal 6 extruding rubber stoppers 7, reaches rifle head 8 and tubulation sealing.This ball valve 4 is used for source of the gas control, and this Pressure gauge 5 is used to observe duty, changes through pressure and can judge whether steel wire lump or sponge ball are released the reactor tubulation smoothly.
The invention still further relates to a kind of method of using cleaning gun 1 rust cleaning, connect the work sources of the gas to source of the gas tube connector interface 3 during use, with steel wire lump or sponge bulb stopper in tubulation; The rifle head and the tubulation mouth of pipe that connect cleaning gun 1; Exerting pressure through pedal 6 reaches the sealing function at rifle head and tubulation mouth of pipe place, opens ball valve 4 and connects the work sources of the gas, observes Pressure gauge 5;, pressure descends suddenly after rising earlier; Just can judge that steel wire lump or sponge ball released tubulation smoothly, the work source of the gas of utilization purges and can iron rust residual in the tubulation be blown out several seconds, accomplishes the rust cleaning of this tubulation.This work source of the gas is a 0.7MPa compressed air.
Through testing during the turnaround of unit, this cleaning gun can carry out the stainless steel pompon multiple operation such as rust cleaning and the cleaning of sponge ball tubulation floating dust separately of ethylene oxide reactor tubulation.
Through endoscopy, confirm that rust cleaning is respond well, meet the instructions for use of catalyst change, can substitute traditional sanding derusting process and carry out rust cleaning work.
Through playing the operation of steel wire lump; Avoided the damage of using traditional sanding derusting process that the ethylene oxide reactor tubulation is caused; Can many people operate simultaneously during work, the use of the special-purpose cleaning gun of tubulation has improved reactor processing of rust removing operating efficiency greatly, has improved working environment; And obtained the effect that eliminates rust preferably, solved the difficult problem that the rust cleaning of reactor tubulation does not have specific purpose tool.
Use traditional derusting process, sanding rust cleaning work 69 hours consuming time altogether.Adopt the special-purpose cleaning gun of ethylene oxide reactor tubulation, blow and beat the steel wire lump rust cleaning, replace the sanding derusting process, steel wire lump rust cleaning process 25.5 hours consuming time altogether, 43.5 hours man-hours are saved in sanding rust cleaning work.New method has improved operating efficiency greatly, has effectively shortened maintenance duration.
