Description
Technical field
The present invention, which relates to, belongs to dedusting technical field, and in particular to a kind of high-temperature oil gas, vapor, easily separates out containing carbons
The filtering dust method of the gaseous mixture of thing.
Background technology
High-temperature dusty gas is often produced in industries such as chemical industry, oil, metallurgy, particularly generates coal tar in low order pyrolysis of coal
During oil gas, decomposition gas are to improve Coal Quality, coal material stirs rolling and risen, and causes coal dust in caused admixture of gas to contain
Amount is very high, and easily separates out material such as tar, class bituminous material, coal ash attachment only in high temperature containing carbons in mixed gas
Can exist in environment with gaseous state, temperature is slightly too low or environment is once change, and is easy for slowly separating out from gaseous mixture.
Material such as tar Jiao, class bituminous material, coal ash the attachment rich product in filtering body stomata and filter cake are easily separated out containing carbons, in right amount
Filter cake can allow the filter effect of filtering gas more preferable, but the easy precipitate containing carbons once gathered is excessive, on the one hand can block up
The stomata of filtering body is filled in, on the one hand filter cake can be made gradually to thicken, and then loses filtering function, production is not continued.Even
In the state of filter cavity continuous high temperature, the too high admixture of gas of dustiness is in filter process, because molecule liquefies, be solidifying
Gu the relation between contact environment, temperature change, frequently position is being physically contacted with filtering body, can still engender and contain
The phenomenon that the easy precipitate of carbons such as tar Jiao, class bituminous material, coal ash attachment separate out from gaseous mixture, is enriched in filtering body gas
In hole, and filter cake is set gradually to thicken, forfeiture filtering function, and the replacing of filtering body, stopping production problem will necessarily be brought, for continuous
The large chemical equipment of operation says that stop production to overhaul will necessarily bring huge economic loss.For a long time, either it is domestic still
Foreign countries, high-temperature oil gas, vapor, the easy precipitate containing carbons gaseous mixture dust removal by filtration problem, particularly high Dust Capacity it is mixed
Close oil gas dust removal problem to fail effectively to be solved all the time, it is impossible to form industrialized production, directly affect the entirety of our times
Coal Industrial general layout, substantial amounts of low-order coal can not be utilized rapidly and efficiently.
Chinese patent CN104226028A discloses a kind of high-temperature oil gas, vapor, the gaseous mixture of the easy precipitate containing carbons
Filtering dust method, by will separation gaseous mixture connect and disconnect with two or more filter plants, can be easily one
Filtering mechanism works in individual filter plant for a period of time after, filter mechanism filter capacity in surface and stomata because contain carbons
The combination of easy precipitate such as tar Jiao, class bituminous material and coal ash attachment, thickeies and declines to a great extent so that can not meet just
Often when work, it is switched in another filter plant and goes, ensures that separation process is uninterrupted；And the filter plant being stopped
Reacted by the fertile absorber with slow transitting through such as oxygen-containing gas, carbon dioxide containing gas, vapor, be by Main Ingredients and Appearance gradually
The filter mechanism attachment of carbon reacts away, and becomes the gases such as carbon monoxide and is left out of filter mechanism surface and stomata, was realized
The regeneration of filter structure filter capacity.Chinese patent CN104147862A discloses a kind of high-temperature oil gas, vapor, easily analysed containing carbons
Go out the filtering dust system of the gaseous mixture of thing, including connect the closed disengagement chamber of admission line and discharge duct, described closed point
Filter mechanism is set from intracavitary, the outer surface of the filter mechanism connects with admission line, and inner surface connects with discharge duct, institute
State and filter regeneration mechanism is set in filtering dust system.The present invention by including connection admission line and discharge duct it is close
Close and filter regeneration mechanism is set in disengagement chamber, can be after body running be filtered for a period of time, filtering body filter capacity is because table
Tar coal ash attachment in face and stomata and decline to a great extent when can not meet normal work, by filter regeneration mechanism work
Make, by filtering body it is important return to it is due it is horizontal up, repeated regeneration directly reduces the input of filtering body, also greatly improves
The service life of filtering body.But these patents are not abundant enough to Btu utilization, substantial amounts of waste heat, and regeneration gas are wasted
The temperature control of body is not accurate enough, it is not abundant enough to be contacted with filter mechanism, so that anti-containing the easy precipitate of carbons and regeneration gas
Should be not thorough.
The content of the invention

Effect is lower and mixed gas separation, high temperature cleaning gaseous mixture pass sequentially through exhaust branch pipe, exhaust main discharge；
（2）With the progress of filtering, gradually have containing the easy precipitate of carbons for example tar, class bituminous material, coal ash attachment from
Separated out in mixed gas, block the stomata in filter mechanism, and make filter cake more and more thicker；
（3）When precipitate so that filter mechanism blocks and during cisco unity malfunction, disconnect high-temperature oil gas, vapor, carbon containing
The connection of the gaseous mixture of the easy precipitate of class and the closed disengagement chamber, the closed disengagement chamber being passed through after another preheating, ensured
It is uninterrupted to filter journey；
（4）After regeneration gas is preheated to 450-500 DEG C, it is passed through in the closed disengagement chamber of cisco unity malfunction, duration of ventilation
5-10h, the material being attached in filter mechanism surface and stomata are close with regeneration gas slow reaction, product discharge at high temperature
Disengagement chamber is closed, finally realizes that filter mechanism regenerates；
（5）When the closed disengagement chamber in work can not work because filter mechanism blocks, high-temperature oil gas, vapor, contain
The closed disengagement chamber that the gaseous mixture of the easy precipitate of carbons is switched to after regeneration again works on, the like, realize multiple closed
The periodicity alternation of disengagement chamber and regeneration.
Preferably, the regeneration gas is oxygen-containing gas or vapor.
Preferably, described oxygen-containing gas is that air forms through the dilution of carbon dioxide, nitrogen or vapor, oxygen
Volume content is 3-8%.
