Embodiment Construction

[0021] see figure 1 , 2 In the shown device for cooling the extraction liquid of biomass gasification, the motor 4 is connected with the reducer 5 , and the housing of the reducer is fixed on the bearing seat 6 . The output shaft of the reducer is connected with the intermediate threaded rod 7 , and the other end of the intermediate threaded rod 7 is movably connected with the fixed end 10 . The external thread of the intermediate threaded rod 7 and the internal thread of the threaded pusher plate 8 form a spiral pair. 91 matched guide recess 81, the inner wall of the outer tube 9 coincides with the outer circumference of the threaded push plate 8. Through the rotation of the motor 4, the middle threaded rod 7 is driven to rotate, and then the threaded push plate 8 will move axially along the outer tube 9, pushing the tar accumulated on the tube wall to flow out from the outlet of the extraction solution of the outer tube 9, thereby Clean the inner wall of the outer tube 9 ...

Abstract

The invention discloses a biomass gasification extract liquid cooling device. The biomass gasification extract liquid cooling device comprises cooling pipes and a cooling fan. Each cooling pipe comprises a motor, an outer pipe with fins, a middle threaded rod, a threaded push plate for cleaning tar, a bearing, a fixed end socket and the like, wherein the threaded push plate is matched with the middle threaded rod through a screw pair; and the motor rotates to drive the cleaning plate to axially move so as to periodically clean tar accumulated in the pipe and guarantee the heat exchange effect. The cooling fan is arranged below the cooling pipes. Heat of the cooling pipes is taken away through air blasting, and accordingly extract liquid is cooled. By adopting the biomass gasification extract liquid cooling device, the problem that the heat exchange effect is reduced through a traditional indirect cooling method due to tar accumulated in pipelines is solved; and the environmental protection problem that VOC generated in the air by a direct cooling tower exceeds the standard is solved as well.

Description

technical field [0001] The invention relates to a device for cooling biomass gasification extraction liquid, which belongs to the field of biomass energy. Background technique [0002] In the current biomass gasification technology, there are roughly three ways to purify and remove tar from gasification: (1) cyclone dust collector + multi-stage circulating spray water washing + high-speed centrifuge + condenser, and finally enter the internal combustion generator; (2) ) cyclone dust collector + multi-stage circulating spray water washing + electric coke capture, and then enter the internal combustion generator; (3) cyclone dust collector + electric coke capture + condenser. There is electric coke capture in the latter two purification methods. Since the oxygen content in the combustible gas cannot be effectively controlled during the operation of the project, the risk of electric coke capture is relatively high, and electric coke capture is excluded from engineering applicat...
