Abstract
In the invention, a casing is supported on the support and in the centre of the casing is mounted a baffle filter disposed staggered distributed baffles inside. At the bottom of the baffle filter is connected a cyclone separator, whose bottom end is plugged in the water tank. On top of the baffle filter is set a carbon filter. There is a water jacket between the casing and the baffle filter. Above the water jacket is set a water-filling opening and under it is set a drain tap. By three comprehensive treatments of cyclone dust removal, cooling filtering and absorbent filtering, the tar, the moisture and the dust in the gas are effectively settled, separated and cleaned. The heat of high temp. gas is absorbed by the water jacket and the afterheat in the gas is fully used.
Description
Technical field
The present invention relates to the removing or the processing of combustion products or combustion residue, especially relate to a kind of small biomass gasification furnace gas purifying and residual heat using device.
Background technology
Because biomass gasification technology can be converted into the high-grade imflammable gas with agriculture and forestry organic waste materials such as agricultural crop straw, forestry felling and industrial wood wastes, gas fuel combustion is efficient, cleaning, convenient, therefore, small-sized in recent years family is widelyd popularize in the rural area with biomass gasifying furnace.The living beings gasification produces CO, H
2, CH
4And C
nH
mDeng combustible component, C wherein
nH
mBe down vaporific tar gas hot, be condensed into the tar liquid of thickness under cold conditions, stop up gas pipeline and kitchen range easily, the tarring gas that is condensed into drop is difficult to after-flame, and the particles such as carbon black that produce during burning utilize equipment damage serious to combustion gas.
At present, the subject matter that biomass gasification burning exists is exactly that impurity contents such as tar and dust are too high, causes the gas-purification difficulty, and system can not carry out the long-term safety operation.And small-sized family is simple with the biomass gasification furnace gas purifying apparatus structure, adopts single wet type washing or dry type cold filtration mostly, and it is not thorough that tar is removed, and clean-up effect is not good.Tar and waste water after the washing is directly discharging often, causes secondary pollution easily.In addition, higher from the biological fuel gas outlet temperature that gasification furnace comes out, influential to operator safety.
Summary of the invention
In order to overcome the deficiency of prior art, the object of the present invention is to provide purification efficiency height, compact conformation, easy to operate a kind of small biomass gasification furnace gas purifying and residual heat using device, make the combustion gas after the purification reach clean flammable national standard, waste heat gas is fully used.
The technical scheme of employing of the present invention is: comprise plate washer filter, tangential admission pipe, vertical cyclone separator tube, water tank, bracing frame, cyclone separator, bleeder cock and carbon filter.With housings support on bracing frame, the plate washer filter is equipped with at the housing center, the baffle plate that is interspersed is set in the plate washer filter, termination cyclone separator under the plate washer filter, insert in the water tank lower end of cyclone separator, is water jacket between housing and plate washer filter, and plate washer filter upper end is provided with carbon filter, the water jacket top is provided with a water filling port, and the water jacket below is provided with bleeder cock.
Described cyclone separator is great circle column casing, circular cone tube and three sections compositions of roundlet column casing, is provided with tangential admission pipe and vertical cyclone separator tube in the great circle column casing, and the roundlet column casing inserts in the water tank.
Described carbon filter is inner filler particles shape adsorbent charcoal, fills with the form of grenadine bag.
The present invention compares the beneficial effect that has with background technology: combustion gas is successively through three comprehensive purifyings and cooling, be respectively the cyclone dust removal of cyclone separator, the cooling of plate washer filter and water jacket removes tar, the adsorption filtration of carbon filter makes that tar, moisture and the dust in the combustion gas obtains sedimentation effectively, separates, purification.The heat of high-temperature fuel gas is absorbed by water, and the waste heat in the combustion gas is fully used, and the gas pipeline temperature is reduced, and can prevent that operating personnel from being scalded.This device has purification efficiency height, compact conformation, characteristics such as easy to operate, and the combustion gas after the purification reaches the national standard of clean combustible gas.
Description of drawings
Accompanying drawing is the structural representation of small biomass gasification furnace gas purifying and residual heat using device.
Among the figure: 1, water filling port, 2, the plate washer filter, 3, the baffle plate that is interspersed, 4, water jacket, 5, tangential admission pipe, 6, the vertical cyclone separator tube, 7, water tank, 8, bracing frame, 9, cyclone separator, 10, tap, 11, carbon filter, 12, adsorbent charcoal.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples.
As shown in drawings, the present invention is made up of cyclone separator 9, plate washer filter 2, water jacket 4, carbon filter 11, bracing frame 8, adsorbent charcoal 12.Cyclone separator 9 is provided with tangential admission pipe 5, vertical cyclone separator tube 6, big or small cylindrical drum and circular cone tube, and terminal vertical the insertion in the water tank 7 of roundlet column casing played explosion-proof when gas pressure is too high in the pipeline.Water jacket 4 is a cylindrical drum, and the water jacket top is provided with a water filling port 1, and cooling water adds from the top, and the below is provided with a bleeder cock 10, and hot water is emitted from the bottom.The inner barrel of water jacket 4 is provided with plate washer filter 2, the plate washer filter 2 built-in baffle plates that are interspersed 3, and the integral body that plate washer filter 2 and water jacket 4 are formed is supported by the bottom support frame.Carbon filter 11 inner filler particles shape adsorbent charcoals 12 with the form filling of grenadine bag, can take out by whole easily bag during replacing, and the charcoal that changes can drop into gasification furnace pyrolytic gasification once more.
The biological fuel gas that comes out from gasification furnace enters from the tangential admission pipe 5 of cyclone separator 9, air-flow is rotation at a high speed between vertical cyclone separator tube 6 and cylindrical drum, circular cone tube, under centrifugal force and gravity effect, part dust and tar flow in the water tank 7 along cones wall, and the tar and waste water that precipitates can be discharged from tap.Combustion gas after once filtering enters plate washer filter 2 from vertical cyclone separator tube 6, the baffle plate 3 that is interspersed makes air flow slows, make the cold water generation sufficient heat exchange in high-temperature fuel gas and the water jacket 4, waste heat obtains to utilize, part tar gas condensation in the combustion gas simultaneously, flow in the water tank 7, reach the purpose of gas-liquid separation.Combustion gas behind secondary filter enters carbon filter 11, and combustion gas is divided into countless threads, flows through from the slit of graininess adsorbent charcoal 12, and water vapour and tar gas are finally obtained the fuel gas of cleaning, drying by further adsorption filtration.
The results showed that adopt that tar, dust content reduce greatly in the combustible gas after this device purifies, impurity content complies with the national standard requirements in the combustion gas.
The above-mentioned specific embodiment is used for the present invention that explains, rather than limits the invention, and in the protection domain of spirit of the present invention and claim, any modification and change to the present invention makes all fall into protection scope of the present invention.
