Abstract
A biomass gas purifying cabinet comprises a cabinet body; the upper part of the cabinet body is provided with a gas outlet, and the bottom of the cabinet body is provided with a water outlet; the cabinet body is inside successively provided with a water inlet pipe, a labyrinth-type water washing chamber and a gas inlet pipe from top to bottom; and the pipe orifice of the gas inlet pipe is lower than the liquid level at the lower part in the cabinet body. According to the cabinet, tar is pre-removed through a water body, and the gas inlet speed is adjusted by matching with the efficiency of removing tar through subsequent labyrinth-type water washing, so that maximum optimum removal rate of quantitative biomass gas is realized.
Description
Technical field
The present invention relates to a kind of purifying tank, is a kind of purifying tank for decontamination of biological matter gas specifically.
Background technology
The features such as it is abundant, cheap, renewable, clean that biomass energy has, along with holding of in December, 2009 Copenhagen, Denmark Global climate change meeting, on the earth, the mineral substance energy consumes rapidly, demand is growing, distribute a large amount of CO in finiteness and use thereof
2, SO
2, NO
xdeng gas and the environmental problem such as the atmospheric aerosol causing, acid rain, Global warming, depletion of the ozone layer causes the thinking of people's profound level again, the exploitation of biomass energy causes again people's extensive concern with application, and gasifying biomass is a kind of conventional biomass energy switch technology, coal-tar middle oil in gasification is inevitable by product.At high temperature can there is cracking in tar, be gaseous phase together with gasification gas, but lower than 200 DEG C in the situation that, just start to be condensed into liquid, become the sticky oily matter of black, affect that equipment for gasification is stable, safe operation, cause energy wastage, reduce gasification efficiency; And polynuclear aromatic family in tar ingredients is purifying and environment and human health are formed to serious harm when burning.Taking suitable treatment process to gasification gas is coal-tar middle oil, reduce the component of tar in gasification gas, improve gasification makings amount, is an important subject of biomass gasification technology.
The purification of biological fuel gas there are at present the physical methods such as the chemical process such as thermo-cracking, catalytic pyrolysis and filtration both at home and abroad, wet filter method is that WATER-WASHING METHOD is that water is taken away the part tar in combustible gas, because it is easy to operate, cost is low, is therefore widely used.As disclosed spray chamber in 201010215797.9 of applicant's earlier application, adopt enterprising gas port air inlet, in multilayer labyrinth type washing chamber, cross water and clean, remove the tar containing in biogas.But the biogas that burning produces directly cleans by cascade, even if extended gas circuit footpath by labyrinth type, but it is still very fast in the time constantly supplying gas purification, to cross gas speed, and cleaning performance is poor.
Summary of the invention
After producing for biogas in prior art, directly by the deficiency of water washing cleaning, the invention provides one simple in structure, can effectively take into account the biogas purifying tank of the rate of supplying gas and tar clearance.
The technical solution used in the present invention is: a kind of biogas purifying tank, comprise cabinet, described cabinet top is provided with air outlet, and bottom of cabinet bulk is provided with water outlet, in cabinet, be provided with successively water inlet pipe, labyrinth type washing chamber and inlet pipe from top to bottom, the mouth of pipe of inlet pipe is lower than bottom liquid level in cabinet.
Further, the mouth of pipe of described inlet pipe is inverted cone shape, and the inverted cone shape mouth of pipe down.
Further, described labyrinth type washing chamber is made up of an above side dividing plate and an above upper and lower alternate intervals of central dividing plate, side dividing plate is connected on cabinet sidewall and air passing hole is left in centre, central dividing plate is arranged between cabinet center and cabinet sidewall and left gas gap, and labyrinth type washing chamber orlop dividing plate is side dividing plate.
Further, between the described inlet pipe inverted cone shape mouth of pipe and cabinet sidewall, leave the corresponding air inlet gap of crossing gas gap.
Further, side dividing plate and the central dividing plate of described labyrinth type washing chamber are provided with upper and lower interleaved water hole.
Again further, on the described labyrinth type washing side dividing plate of chamber and the edge of central dividing plate, be equipped with the water eliminator that exceeds its plane.
Adopt technique scheme, the invention has the beneficial effects as follows: the inverted cone shape mouth of pipe of inlet pipe passes in cabinet under liquid level down, by inlet pipe lead to into biogas first pass in water, remove part tar; Biogas is again by glowing upward through air inlet gap in water, by adjusting the middle air passing hole of the undermost side dividing plate in corresponding labyrinth type washing chamber, air inlet gap, control the washing efficiency that air inlet rate meets labyrinth type washing, guarantee quantitative biomass gas air inlet, cross air water and wash, to reach maximum, best tar clearance.
The present invention adopts and removes in advance tar by water body, coordinates the efficiency of follow-up corresponding labyrinth type washing tar removing to adjust air inlet, realizes the maximum of quantitative biomass gas, best clearance.
