Description
Technical field
The invention belongs to deduster jetting deashing equipment technical field, particularly the energy-saving back-blowing dust removing device of one.
Background technology
At present, at chemical industry, oil, the industries such as metallurgy often produce high-temperature dusty gas, because different process needs to carry out dedusting to high-temperature dusty gas, realize gas solid separation and gas purification, often use and carry out filtration by the filter core in deduster and realize gas solid separation, dusty gas through filtration, purification enters air-purifying chamber, dust-filtering is stayed in the dirt pocket of deduster, be deposited in ash bucket, and the filter core of deduster its outer surface in dust removal by filtration process can adsorb a large amount of granule dusts, along with dust constantly increases, filter quality will be affected, therefore the dust to cartridge surface is piled up is needed to remove, now injection tube is generally used to realize reverse deashing, the space before but the result of blowback necessarily makes the gas purified again enter purification, and owing to there is certain speed and impact in Purge gas uphill process, must need to increase gas boosting equipment in the process realizing blowback, and improve the very large external world could realize its airflow direction transformation and speed-raising for pressure, the capacity loss of pressure-raising equipment certainly will be increased in the middle of this, be unfavorable for increasing work efficiency.Also have part producer to design and adopt dust removal with machine device, as brush is installed in manipulator front end, or mechanical oscillation method, but not only complex structure, and due to action consistency poor, can not well thorough deashing dedusting; And easily damaging the filter core of deduster, the air-purifying chamber that after filter core damage, dust enters deduster will be brought subsequent handling into and causes great loss by removing pollutant gas.Therefore, need badly and make further improvement and bring new ideas in filter core dedusting, provide a kind of filter core deashing device of efficient energy-saving to solve the problems referred to above.
Summary of the invention
The object of the invention is to solve the problems of the technologies described above, provide a kind of with low cost, can fast dust-removing, energy-saving back-blowing dust removing device that ash-removal effect is good.
For achieving the above object, the technical solution used in the present invention is: a kind of energy-saving back-blowing dust removing device, it comprises purge gas carrier pipe and pure qi (oxygen) collecting pipe, described pure qi (oxygen) collecting pipe connects purge gas carrier pipe by cross-over joint, and described purge gas carrier pipe and pure qi (oxygen) collecting pipe are respectively arranged with stop valve.
Described pure qi (oxygen) collecting pipe comprises at least two group gas collection pipe units, and described gas collection pipe unit converges at below described cross-over joint, and described gas collection pipe unit is serially connected with adjustable device in one-way on state.
Described adjustable device in one-way on state comprises the one-way conduction spool of controller, expansion link and expansion link front end.
Described adjustable device in one-way on state comprises ball seat and is provided with the spool of one-way conduction component.
Described gas-collecting pipe unit bottom is the collecting hood mouth of venturi tube structure.
The air inlet of described purge gas carrier pipe arranges deflector, and described deflector arranges turning control mechanism.
. described purge gas carrier pipe is entering deduster position set temperature checkout gear, and described temperature-detecting device connects the heater of described purge gas carrier pipe.
Described heater is electric heater or burner.
The present invention connects purge gas carrier pipe at described pure qi (oxygen) collecting pipe by cross-over joint, described purge gas carrier pipe and pure qi (oxygen) collecting pipe are respectively arranged with stop valve, when dusty gas is filtered in normal collection time, stop valve on described purge gas carrier pipe and pure qi (oxygen) collecting pipe is closed respectively and opens, do not affect the outflow of normal Purge gas and enter next process procedure, stop valve in time needing blowback dedusting on described purge gas carrier pipe and pure qi (oxygen) collecting pipe opens and closes respectively, the dusty gas be then filtered no longer continues up, now the HTHP purge gas of purge gas carrier pipe enters in the filter core below described pure qi (oxygen) collecting pipe fast, and then the object that realization is removed the dust stratification of filter core outside, further, described pure qi (oxygen) collecting pipe comprises at least two group gas collection pipe units, described gas collection pipe unit converges at below described cross-over joint, described gas collection pipe unit is serially connected with adjustable device in one-way on state, when reverse gas cleaning, one of them treats that the adjustable device in one-way on state on the gas collection pipe unit of blowback is set to conducting state, then purge gas enters the filter core inside of bottom by described adjustable device in one-way on state, simultaneously in other gas collection pipe units not carrying out reverse gas cleaning gas in company with carrying out blowback together, not only save purge gas consumption, and achieve the automatic turning of gas flow direction due to inside, pressure-raising equipment loss for purge gas also reduces much, improve efficiency and the economic benefit of reverse gas cleaning, the structure various structures of described adjustable device in one-way on state all can realize, one adopts to be arranged at described gas collection unit side version, comprise the controller of serial connection, expansion link and one-way conduction spool, running status is: described one-way conduction spool original state is in the pipeline side of described gas collection unit, do not affect gas in pipelines flowing, described controller action when needs blowback time, drive expansion link and the action of one-way conduction spool, described one-way conduction spool is in described pipeline, purge gas is only allowed to flow through, avoid gas backstreaming and reaction, another kind is serially connected in the version in described gas collection unit, comprise ball seat and the spool being provided with one-way conduction component, described spool is positioned on the gas passage of described gas collection unit, when the direction of described Spool rotating 180 degree then one-way conduction changes, achieve the adjustment in one-way conduction direction, treat when blowback that the described gas collection unit overdraught of blowback allows descending, other allow air-flow up, well achieve the self-loopa of air-flow, the backflow of the gas also avoided and reaction, further, the air inlet of described purge gas carrier pipe arranges deflector, described deflector arranges turning control mechanism, described deflector can be controlled gas is flowed directly into treat in the gas-collecting pipe unit pipe of blowback, the self-loopa air-flow to inside is formed is avoided to have an impact, ensure its good secondary pressurized effect, improve injecting velocity, effectively improve the efficiency of reverse gas cleaning, described purge gas carrier pipe is entering deduster position set temperature checkout gear, described temperature-detecting device connects the heater of described purge gas carrier pipe, the temperature of blowing gas can be ensured, avoid blowing air temperature low affect coal tar wet goods composition in dusty gas condensation and damage equipment, described heater mode is various, can be electric heater or burner etc.
Modern design of the present invention is ingenious, the self-loopa flowing of internal gas is achieved by arranging adjustable device in one-way on state on gas collection pipe unit, blowback air-flow is defined to the booster action of good secondary pressurized, with low cost, device security is reliable, the cycle of operation is long, improves the efficiency of dust collection to filter core, and reduce operating cost, there is good economic benefit, new approach has been started for filter core dedusting aspect, has had good value for applications.
