Description

A kind of brown coal hydrogasification reduction 3-stage dust-removal is cooling, automatic gas-locking device

Technical field

The invention belongs to energy developments and environmental technology field, cold more particularly, to a kind of brown coal hydrogasification reduction 3-stage dust-removal But, automatic gas-locking device.

Background technology

In recent years, with the development and application of performing comprehensive coal mining technology, the exploitation ratio of fine coal gradually increases, dry for fine coal The various explorations and experiment for evaporating progress reach its maturity.Compared with coal gasification and liquefaction technology, coal carbonization can be relatively mild Under conditions of, coal gas, tar and semicoke are obtained, is a kind of both economical coal transformation routes.Coal carbonization process is generally dry It evaporates in equipment such as gas retort and carries out, the gas-phase product generated during the dry distillation of coal is commonly referred to as " dry distillation gas ", wherein containing A certain amount of dust can not only reduce the quality of coal gas and tar product, but also influence the steady of distillation system if not removed Fixed operation.In addition, it is in gaseous tar also to contain in dry distillation gas.Cooling treatment is purified to dry distillation gas, forbids to have occurred not Same method.

China's oil starvation, few gas, rich coal energy resource structure feature be doomed AND ENERGY RESOURCES CONSUMPTION IN CHINA will be for a long time based on coal, coal at present Mine mechanical mining degree is relatively high, and lump coal only accounts for 30% or so, and a large amount of cheap fine coal in major coal place of production can not be effective Utilization.Semi-coke, also known as semicoke, coke, structure are bulk, and granularity is generally in 3mm or more, and color is in light/dark balance, currently, blue There are mainly two types of specifications for charcoal:When soil refining semi-coke, second is that mechanism semi-coke；Although the semi-coke of two kinds of specifications is same high-quality Cleaned coal is refined, but because the difference of production technology and equipment, cost and quality are also made a world of difference.Wherein good semi-coke production Shenmu County and Fugu in Shaanxi.But after powder destructive distillation the dregs of fat can not efficiently separate and carbonization gas in dust-laden the problem of remain unchanged Perplex all multiple enterprises and scholar.Existing dedusting grain bed mainly does filtrate with quartz sand or Ceramic Balls, cannot effective profit With the heat of carbonization gas, and filtrate is to recycle, the dust content enrichment in filtrate to a certain extent when, need explosion Blowback promotes sorting and returns system, it is therefore desirable to which external air source completes this process.In addition, existing grain bed in order to Ensure that the tar in carbonization gas is non-cohesive on filtrate, for running temperature all at 500 DEG C or so, temperature is excessively high.The pyrolysis of coal, still Such as the air-distillation process of tar, if not dedusting, that is difficult oil and water, and oil and oil separate.This petroleum vapor recovery side Formula is conducive to oil quality raising oil at three kinds of oil of heavy, medium and light, is also beneficial to business economic value and improves, also favorably It is processed in follow-up oil product.After carrying wax such as heavy oil, hydrogen is added to form heavy diesel fuel component, or directly as industrial fuel oil, or directly make For carbon black raw oil etc.；Light oil is the highest oil product of economic value, is gasoline fraction, by simple rectifying or adds hydrogen, can get Solvent naphtha and premium.Oil-water separation, dust removing effects are directly related to oil quality, very heavy to tar following process It wants.Patent CN96207496.9 is a kind of rotary furnace formula retort gas generator, it removes destructive distillation using cyclone separating tube The dust of coal gas.Patent CN921000912.7 is a kind of method and apparatus producing dry distillation gas, the dedusting dress of dry distillation gas Set is cyclone separator or inertia separator.But it is found in putting into practice, the heavy tar and dust of generation attach to cyclone separator Inner wall not only causes cyclonic separation efficiency to decline, but also influences the longtime running of system.104226064 A of patent CN are a kind of Dust-laden carbonization gas dust-extraction unit.Including dedusting cavity, the top of dedusting cavity is equipped with filtrate import, and bottom is exported equipped with filtrate, Snorkel is equipped with below dedusting cavity wall；The hot carbonization gas temperature of the device from bottom to top continuously decreases, cold conditions filtrate Temperature from top to bottom gradually rises, it should which saying has certain temperature gradient, is conducive to the progress of dedusting.

Above several devices, which should be said, all has certain dust removing effects, and is also now more but single Often efficiency of dust collection is not high for one device, enters follow-up equipment with a certain amount of dust-laden particle and heavy tar, to follow-up light The quality of matter tar, the quality of coke-stove gas, line clogging etc. bring prodigious influence, often dust removing effects quality, and heavy is burnt The number of oily removal rate directly determines the quality and production efficiency of enterprise product.
