Description

Technical Field

[0001] The utility model relates to the technical field of water cooling devices, in particular to water cooling equipment for a biomass gasifier. Background Art

[0002] The existing water cooling equipment of the biomass gasifier is used to cool the hot water in the gasifier and absorb the heat generated in the furnace. This can effectively control the temperature of the gasifier and ensure that it operates within a safe and efficient range.

[0003] However, when it is in use, its cooling pipe is a traditional smooth pipe with a small surface area, resulting in low heat transfer efficiency and possibly insufficient cooling effect. For example, a Chinese patent discloses a "biomass gasifier water cooling device" with the application number "201721242424.4". This device includes a water-cooled tube array arranged in the gasifier and a cooling tower arranged outside the gasifier. The water-cooled tube array includes a water inlet pipe, a cooling pipe and a water outlet pipe. The water inlet pipe includes an inlet elbow and a water inlet straight pipe connected to the inlet elbow. The water outlet pipe includes an outlet elbow and a water outlet straight pipe. The water outlet straight pipe is connected to the water inlet straight pipe through at least one cooling pipe. Both the water inlet pipe and the water outlet pipe are connected to the cooling tower through pipes. This device has a simple structure and is easy to disassemble. The cooling water can be recycled. However, when it is in use, its cooling pipe is a traditional smooth pipe with a small surface area, resulting in low heat transfer efficiency and possibly insufficient cooling effect.

[0004] The purpose of the present utility model is to solve at least one of the technical problems existing in the prior art and to provide a water-cooling device for a biomass gasifier, which can guide the heat in the cooling pipe to the heat dissipation sleeve through the heat-conducting fins.
