Tar separation unit and tar separation system

Abstract

The invention relates to a tar separation unit and a tar separation system. The tar separation unit comprises a hopper, a first distributor and a second distributor, wherein the first distributor andthe second distributor are located above the hopper, the first distributor is communicated with the hopper through two first pipes, the hopper is communicated with the second distributor through at least two second pipes, and cooling systems are arranged around the first pipes and the second pipes; and a bucket is communicated to the bottom of the hopper. The tar separation unit has a condensationseparation effect, tar components collected in each tar separation unit are relatively uniform; and the first pipe or the second pipe in the same tar separation unit are circumferentially distributed, the water supply of multiple first pipes can be finished only through a water supply pipe, so that the structure can be simplified.

Description

technical field [0001] The invention relates to the technical separation field of biomass, garbage, industrial organic waste and coal coking, and specifically relates to an annular multi-stage tar separation unit and a multi-stage tar separation system. [0002] The invention belongs to the fields of biomass pyrolysis gasification, garbage pyrolysis gasification, coal gasification, coking chemical gas purification and tar separation, and specifically relates to a tar separation unit and a tar separation system, in particular to an annular tar separation unit And multi-stage tar separation system. Background technique [0003] The pollution of garbage to the environment has been raised to the national agenda. According to the national document No. 227 in 2016, the four departments jointly issued the "Opinions on Further Strengthening the Incineration and Treatment of Municipal Domestic Waste", which fully reflects the country's emphasis on garbage disposal. Garbage is harmle...

Problems solved by technology

However, this method mainly has poor cooling effect, and a large amount of water and tar are mixed to form secondary water pollution. In order to solve the above problems, a "multi-stage tar separator" has been publicized. This process adopts external cooling, and the gas and cooling water are separated. This solves the problem of water pollution and has the advantages of better cooling effect. However, due to the gradual development of waste pyrolysis and gasification technology projects in the market from small projects to large-scale projects, this single-tube arrangement and multi-stage decoking method is difficult to adapt to large-scale projects. , because the condensation method is used to decoke, the smaller the diameter of the cooling pipe, the better the cooling effect. The larger the diameter of the gas pipeline and the thinner multi-pipe arrangement of the cooling pipeline, the disadvantages are that the equipment is too large, the cost is high, and the floor area is large.
