Embodiment Construction

[0034] The present invention will be described in detail below in conjunction with examples. It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. For the convenience of description, if the words "up", "down", "left" and "right" appear in the following, it only means that the directions of up, down, left and right are consistent with the drawings themselves, and do not limit the structure.

[0035] Such as Figure 1 to Figure 4 As shown, a double-cycle heat exchange tar separation system includes an air inlet pipe 20, three successively connected tar separation units and an air outlet pipe 21. Viewed along the airflow direction, the air inlet pipe and the first tar separation unit connected, the outlet pipe communicates with the outlet of the tar separation unit at the end; a first valve 14-1 is installed on the inlet pipe, and a second valve 14-2 is installed on the o...

Abstract

The invention relates to a double-circulation heat-exchange tar separation system which comprises a gas inlet tube, at least two tar separation units and a gas outlet tube as well as a first branch tube and a second branch tube, wherein the tar separation units are connected in series sequentially; a first valve is mounted on the gas inlet tube; a second valve is mounted on the gas outlet tube; one end of the first branch tube communicates with the gas inlet tube on the upstream side of the first valve, and the other end of the first branch tube communicates with the gas outlet tube on the upstream side of the second valve; one end of the second branch tube communicates with the gas inlet tube on the downstream side of the first valve, and preferably, the other end of the second branch tube communicates with the gas outlet tube on the downstream side of the second valve; a third valve is mounted on the second branch tube; and a fourth valve is mounted on the first branch tube. By adopting the system, the problems that pipelines are blocked by condensate or the condensate is stuck to the pipelines in the tar separation process can be effectively solved, normal and stable operation of the system can be ensured, and the production efficiency and the tar separation effect can be improved.

Description

technical field [0001] The invention relates to a double-cycle heat exchange tar separation system, which belongs to the fields of biomass pyrolysis gasification, domestic waste pyrolysis gasification, industrial solid waste, and coking chemical gas purification tar separation. Background technique [0002] my country is very rich in biomass resources, mainly including crop straw, firewood, household garbage, industrial solid waste and other material resources. Using advanced refining and pyrolysis technology, biomass can be converted into new energy products, reducing the cost of petroleum and petrochemical products. consumption, and can protect the ecological environment very well, develop new energy growth points, and promote beautiful urban and rural construction. [0003] At present, the market mainly adopts tower-type internal cooling spray decoking method, centrifugal separation and other processes for decoking. In the lower temperature parts of the existing decoking ...
