Background technology
High pressure, large capacity fluidized-bed coal gasification technology are the tap and key of clean coal technology.Modern coal gasification skill
Art is often combined with gas turbine, formed integrated gasification combined cycle for power generation (IGCC) system, production electric power, steam with
And coal-based chemicals.Gas turbine, fine coal chemistry product process units, quality and cleanliness factor for coal gas be required to it is higher,
Underproof coal gas often acceleration equipment aging, influence catalyst life, even result in device parking, cause great economy to damage
It loses.Therefore, the research and development of high-effective gas purifier are the hot and difficult issues of coal chemical technology in recent years.
Gas purification is the mistake for effectively being removed to Multiple components in coal gas, and being cooled down to coal gas and conveyed simultaneously
Journey.It refers specifically to, by means such as washing, filtering, reactions, extract the production of the high added values such as coal tar, naphthalene, anthracene and the crude benzol in coal gas
Object, and NO is removed simultaneouslyX, hydrogen sulfide, the pollutants such as cyanide, obtain the process means of clean gas.
Traditional gas purification process, generally use ammonia scrubbing, raw coke oven gas will pass through just cold, de- benzene, de- naphthalene, catch and wash
After several process processing such as oil, desulfurization, saturator method deamination, qualified coal gas can be just obtained.This technology device is complicated,
Energy consumption needs to build tar recovery system in a whole set of water treatment facilities and ammonium hydroxide, investment is higher, and long compared with high, wastewater flow rate is big
Periodic duty is difficult.With the continuous improvement that environmental protection standard and supporting technology require gas quality, coal chemical industry enterprises usually need
It to increase electric fishing collection tar device, de-NOx devices etc. newly on original Process ba- sis, relevant criterion requirement could be reached reluctantly.
It is still difficult by cyclone dust removal containing a large amount of tar and fine ash in coal gasification processes, especially coal pyrolysis gas
To remove the particle of small particle, and tar capture rate is relatively low.Therefore, research and development one kind can efficient removal coal tar, washing dust,
Gas cleaning device stable, environmental pollution is small, water consume is small realizes efficient gas purification effect, is Modern Coal-based Chemical
The active demand of development.
Invention content
The purpose of this utility model is to provide it is a kind of it is efficient, stable, environmental pollution is small, water consume is small and same
Dust catching, tar recycling, the oil wash gas cleaning device of coal gas cooling are realized in device.
In order to achieve the above objectives, the technical solution adopted in the utility model is：Gas exit, lower end are offered including upper end
The purifying column of heavy oil outlet is offered, the purifying column sidewall upper is provided with the first washing oil entrance, the first washing oil inlet port
It is provided with the distribution grid that purifying column is sprayed into after washing oil is uniformly dispersed, purifying column side wall lower ends are provided with gas entry, coal gas
Entrance enters the washing oil liquid level at purifying column bottom or less by diversion elbow and the distributor being arranged in diversion elbow tail portion.
The distributor section is in regular zigzag.
Barrier cover is provided on the diversion elbow.
The purifying column lower end offers the first heavy oil outlet (8) and the second heavy oil outlet (9)
The purifying column sidewall upper is additionally provided with elutes the second washing oil entrance on inner wall of tower by washing oil.
The purification tower bottom is further opened with access hole.
The utility model is simple in structure, investment is less, fluid resistance is small, maintaining is convenient；Use similar mix
Oil wash technique purifies coal gas, is capable of the tar product of higher yields obtained in coal gas, for the polycyclic aromatic hydrocarbons chemical combination such as naphthalene, anthracene
Object, effect are especially apparent；Using distributor, coal gas gas velocity can be substantially reduced, gas entry is directly entered tower through bend pipe water conservancy diversion
Below the washing oil liquid level at bottom so that the coke powder in coal gas is fully contacted with washing oil, to by deep invasion.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram of the utility model distributor 6.
Specific implementation mode
The utility model is described in further detail below in conjunction with the accompanying drawings.
Referring to Fig. 1, the utility model includes that upper end offers gas exit 1, lower end offers the purifying column that heavy oil exports,
Coking, purification Deethanizer design tower is caused to be void tower for the blocking and internal liquid temperature that avoid oil wash gas cleaning device is excessively high,
Its main feature is that it is simple in structure, investment is less, fluid resistance is small, maintaining is convenient.Purifying column sidewall upper is provided with first,
Second washing oil entrance 2,3, washing oil enter the present apparatus from the first washing oil entrance 2 and the second washing oil entrance 3.Wherein, the first washing oil enters
Mouth 2 is provided with distribution grid, and washing oil is sprayed into tower after being uniformly dispersed on distribution grid after entering, the next coal with bottom of device uplink
