Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, the present invention provides a technical solution: the utility model provides a waste heat recovery device for biomass power generation, which comprises an outer shell 1, the both sides of shell 1 are provided with air-supply line 3 and go out tuber pipe 4, the outer wall fixed mounting of shell 1 has purification box 6, and purify box 6 intercommunication air-supply line 3, the outer wall of shell 1 is provided with water pump 9, the inside of shell 1 is provided with inner shell 2, the inside fixed mounting of inner shell 2 has air exhauster 7, and the one end of air exhauster 7 fixed connection air-supply line 3, the inside fixed mounting of inner shell 2 has water tank 5, and 5 one side fixed connection gate valves 11 of water tank, the surface winding of water tank 5 has raceway 10, and the delivery port of the one end fixed connection water pump 9 of raceway 10, the one end that water raceway 10 kept away from water pump 9 is worn out shell 1 intercommunication and is by box 8, water tank 5.

Referring to fig. 2, the bottom of the stopping box 8 is connected to the water tank 5, and the stopping box 8 is provided with water seepage holes 15 so that water can enter the water tank 5 at a uniform speed.

Referring to fig. 1, a water flowing hole 16 is formed in the housing 1 to facilitate water flowing out when the inside of the device is cleaned.

Please refer to fig. 2, the clamping plates 12 are symmetrically installed inside the stop box 8, the bottom of the stop box 8 is located at the clamping plates 12 and is connected with the limiting plate 13 in a sliding mode, the bottom of the limiting plate 13 is fixedly provided with the floating block 14, the limiting plate 13 is made of rubber, the height of the water level can be automatically adjusted, and the water tank 5 is prevented from entering water all the time, so that the water is not completely heated, the limiting plate 13 can be completely attached to the clamping plates 12, and water is prevented from permeating.

Referring to fig. 1, heat insulation cotton is arranged in a gap between an outer shell 1 and an inner shell 2 to absorb lost heat and avoid waste of heat.

Referring to fig. 1, a sponge layer is sleeved on a part of the water tank 5 exposed to the outside of the outer shell 1, so that safety accidents caused by mistaken touch of people due to overhigh external temperature of the water tank 5 caused by heat transfer are prevented.
