Abstract

The utility model relates to biomass pyrolysis gasification devices, in particular to a biomass pyrolysis vinegar cooling and collecting device which comprises vinegar separating condensers. The biomass pyrolysis vinegar cooling and collecting device is characterized in that funnel-shaped flow collectors (7) are mounted at bottoms of the vinegar separating condensers, a vinegar collector (8) is connected to an outlet of each funnel-shaped flow collector (7), and a vinegar outlet (9) is arranged on each vinegar collector (8). An existing vinegar collecting device (see also from the first patent of the background technology) is modified, water is still used as sealing liquid at the bottoms of the condensers, but is no longer used for collecting cold vinegar and is only used for preventing explosion, accordingly, the shortcoming of low concentration of vinegar produced when original vinegar production equipment just starts to produce the vinegar is overcome, the biomass pyrolysis vinegar cooling and collecting device has the advantages of simple structure, capability of preventing explosion, good sealing performance, convenience in maintenance and the like, the density (in the unit of g/cm<3>) of reed vinegar is increased to 1.005 from the original 1.001 when reed vinegar production is just started, the density of the produced vinegar is stable, and application to follow-up agricultural production is facilitated.

Description

The liquid cooling of a kind of biomass pyrolytic vinegar is collection device but

Technical field

The utility model relates to the biomass pyrogenation gasification device, and the liquid cooling of especially a kind of biomass pyrolytic vinegar is collection device but.

Background technology

Patent two, wood vinegar tar cooling-collecting device (the patent No.: 201020275662.7, publication number CN201729815U), its device comprises gas feed, pneumatic outlet, heat exchanger shell, entrance of cooling water, cooling water outlet, heat transfer tube, fin, interchanger bottom collection bucket, interchanger bottom leakage fluid dram, shell separator, baffle, separator base plate, separator bottom collection bucket, separator bottom leakage fluid dram, separator gas import, separator gas outlet, interchanger base plate.Feature is that interchanger and separator are all vertically installed, and links to each other by straight tube.Pyrolysis gas is cooled through heat exchange after entering interchanger, and a small amount of wood vinegar and tar liquid collect in base plate in interchanger, and inflow heat exchanger bottom collection bucket, and most of tar and wood vinegar enter in the separator with pyrolysis gas.Pyrolysis gas is carried the baffle in tar and the continuous impingement separators of wood vinegar secretly, and in knockout process, separate, pyrolysis gas after the separation is discharged from the separator gas outlet, and tar and wood vinegar under separating stay along baffle plate, and flows into separator bottom collection bucket.The utility model has realized containing cooling and the liquid collecting of tar and wood vinegar high temperature pyrolysis gas, have simple in structure, good airproof performance, the advantage such as easy to maintenance and reusable.

In addition, patent three, the coke tar vinegar liquid condensing separating device of the Biomass Gasification ﹠ Power Generation (patent No.: 200720124862.0, publication number CN201071359), its apparatus structure is Stainless Steel Wire screen plate on the device of middle and upper part in the case shell of coke tar vinegar liquid condensing separator, Stainless Steel Wire screen plate under the device of middle and lower part, there is condensate pipe the centre, water inlet pipe and the rising pipe of condensate pipe two ends welding passband valve, shell wall welds respectively pass-out tracheae B one end and escape pipe C one end between the top shell of upper Stainless Steel Wire screen plate and case shell, and the other end of escape pipe C inserts in the gas-holder tank.Have simple and compact for structurely, fabrication and installation are convenient, are conducive to condensation separation, reclaim useful matter, reduce the characteristics such as environmental pollution.

The most obvious defective of above prior art is: the utility model wood vinegar tar cooling-collecting device of the rich bioenergy Science and Technology Ltd. of the coke tar vinegar liquid condensing separating device of the utility model Biomass Gasification ﹠ Power Generation of Li Xiaokun and Hefei moral invention lacks safe explosion-proof device, pyrolysis might produce back draft in producing, and the gas-liquid separation purification system that is used for the agriculture and forestry biomass materials pyrolysis gas of Nanjing Forestry University's invention is provided with explosion-proof equipment, its explosion-proof equipment is to adopt hydraulic seal in vinegar liquid cooling condenser bottom, although avoided explosion hazard, but the vinegar liquid that condensation is collected is to flow out from the bottom after mixing with sealed bottom liquid (water), a kind of new raw material vinegar liquid of each production need to be changed the sealing fluid water, and the sealing water yield is very large, it is very low to begin concentration to the vinegar liquid that makes each new raw material production, needing to produce large content of starting materials and expending just can reach for a long time needs concentration, and can not production short run vinegar liquid product.

The utility model content

The purpose of this utility model provides but collection device of a kind of simple in structure, explosion-proof, good airproof performance and biomass pyrolytic vinegar liquid cooling easy to maintenance.

The liquid cooling of a kind of biomass pyrolytic vinegar is collection device but, comprise vinegar liquid separation condenser, be characterized in: in described vinegar liquid separation condenser bottom the funnel-form current collector is installed, the outlet of this funnel-form current collector connects a vinegar collection, is provided with vinegar liquid leakage fluid dram at this vinegar collection.

Wherein vinegar liquid separation condenser has two, is separately installed with a funnel-form current collector in each vinegar liquid separation condenser bottom, and passes through pipeline connection between two funnel-form current collectors.

The utility model improves existing vinegar liquor collecting device (referring to the patent one of background technology), increase a funnel-form current collector and a small-sized vinegar collection in original vinegar liquid separation condenser bottom, directly collect the vinegar liquid of condensation, the vinegar liquid sealing that the explosion-proof use self of small-sized vinegar collection produces; Condensation sealed bottom liquid still makes water, but do not regather cold vinegar liquid, only do explosion-proof use, overcome so vinegar liquid concentration that former vinegar liquid production unit begins to produce low and shortcoming, have simple in structure, explosion-proof, good airproof performance, the advantage such as easy to maintenance is produced the liquid-tight degree (g/cm of reed vinegar of beginning ³) bring up to 1.005 by original 1.001, and the liquid-tight degree of vinegar of producing is stable, is convenient to the application in the follow-up agriculture production.
