Description

Technical Field

[0001] This utility model relates to the field of energy recovery technology, specifically a waste steam heat recovery device for noodle-making workshops. Background Technology

[0002] Steam heat recovery units are technological devices used to improve energy efficiency and reduce energy waste. They recover steam or waste heat generated during industrial production processes and convert it into usable energy. This type of device not only reduces energy costs for businesses but also meets environmental protection requirements for energy conservation and emission reduction.

[0003] The existing Chinese utility model patent with publication number CN204853414U discloses a waste steam heat energy recovery device, including an evaporation chamber, a heat energy conversion chamber, and a water tank. The vaporization chamber and the heat energy conversion chamber are separated into two independent spaces by a heat-conducting layer. The heat energy conversion chamber is provided with an air inlet and a waste vent for waste steam, and the evaporation chamber is provided with a steam outlet and a water inlet. The water tank is connected to the water inlet through a water inlet pipe. Compared with the prior art, this utility model first uses a gas compressor to pressurize and heat the waste steam, improving the heat exchange efficiency of the waste steam. Then, through heat transfer, it rationally utilizes the residual heat of the waste steam, heating an appropriate amount of soft water through the heat-conducting layer until it evaporates, producing clean steam. Then, the clean steam is recovered, pressurized, and heated by a steam compressor to improve the heat energy grade of the steam, and reused in steam heating equipment, effectively recovering the heat energy from the waste steam and achieving the purpose of energy saving and emission reduction.

[0004] Existing steam heat recovery devices generally achieve the effect of heat recovery by using high-temperature steam to drive a turbine to generate electricity. However, since a certain torque is required for the turbine to start rotating, and the steam in the noodle-making workshop cannot generate a large enough circumferential force to drive the turbine, the turbine may stop rotating due to insufficient steam thrust.

[0016] 1. This utility model, through the setting of the guide pipe, the height of the guide pipe is the same as the height of the guide column, and the center of the guide pipe and the guide column are on the same vertical line. The lower end of the inner wall of the guide pipe is a conical structure.

The lower end of the inner wall of the guide tube 13 is tapered. The outer diameter of the top edge of the guide column 14 is larger than the outer diameter of the bottom edge, and the outer side of the guide column 14 is chamfered. The shaft of the generator 15 runs vertically through the generator 15, and the lower half of the shaft of the generator 15 is rotatably connected to the limiting frame 11 below the guide column 14 through the limiting bearing 12. The bottom of the inner part of the guide cover 16 is chamfered, and the inner diameter of the guide cover 16 is smaller than the outer diameter of the turbine 114.

[0028] The transmission gear 110 is mirror-symmetrically mounted on the front and rear sides of the fixed shaft 18 with the center of the fixed shaft 18 as the reference. The transmission gear 110 is rotatably connected to the fixed shaft 18 through the connecting bearing 19. The transmission shaft 111 is rotatably connected to the limiting frame 11 above the guide column 14 through the limiting bearing 12. The drive gear 112 at the lower end of the transmission shaft 111 is vertically mirror-symmetrically mounted to the connecting gear 17 at the upper end of the generator 15 shaft. The connecting gear 17, transmission gear 110, and drive gear 112 mesh with each other, and the gear ratio between the connecting gear 17 and the transmission gear 110 and drive gear 112 is 4:2:1. The impeller 113 is installed in a through-hole manner at the center of the transmission shaft 111, and the impeller 113 is fixedly connected to the transmission shaft 111. The outer edge of the turbine 114 is located between the inner wall of the guide pipe 13 and the outer wall of the guide column 14.

[0029] Specifically, the limiting tube 1 restricts the position of steam, the limiting frame 11 restricts the position of the guide tube 13 and the guide column 14, the limiting bearing 12 facilitates the rotation of the drive shaft 111, the guide tube 13 and the guide column 14 guide the steam, the generator 15 generates electricity, the guide shroud 16 restricts steam from entering the interior of the limiting tube 1 from the center, the connecting gear 17 facilitates the drive gear 110 to drive the generator 15 to rotate, the fixed shaft 18 restricts the position of the drive gear 110, the connecting bearing 19 facilitates the rotation of the drive gear 110, the drive gear 110 can drive the connecting gear 17 to rotate under the drive of the drive gear 112, the drive shaft 111 facilitates the impeller 113 to drive the drive gear 112 to rotate, the drive gear 112 can drive the drive gear 110 to rotate, the impeller 113 can drive the drive shaft 111 to rotate, and the turbine 114 can drive the generator 15.

[0030] In use, the height of the guide pipe 13 is the same as the height of the guide column 14, and the centers of the guide pipe 13 and the guide column 14 are on the same vertical line. The lower end of the inner wall of the guide pipe 13 has a tapered structure. The outer diameter of the top edge of the guide column 14 is larger than the outer diameter of the bottom edge, and the outer side of the guide column 14 is provided with a chamfered structure. At the same time, the bottom of the inner part of the guide shroud 16 is provided with a chamfered structure, and the inner diameter of the guide shroud 16 is smaller than the outer diameter of the turbine 114. The guide shroud 16 can restrict steam from entering from the center of the limiting pipe 1. The steam enters the limiting pipe 1 to generate a greater circumferential force on the turbine 114. After passing through the turbine 114, the steam is limited by the guide pipe 13 and the guide column 14, and blown towards the impeller 113 with a smaller passage area. This method enables the steam to generate a greater circumferential force, so that the steam drives the turbine 114 and the impeller 113 to rotate.

The drive gear 112 at the lower end of the transmission shaft 111 and the connecting gear 17 at the upper end of the generator shaft 15 are vertically mirror symmetrical. The connecting gear 17, transmission gear 110 and drive gear 112 mesh with each other, and the gear ratio between the connecting gear 17 and the transmission gear 110 and drive gear 112 is 4:2:1. When the impeller 113 rotates, it can drive the transmission shaft 111 to rotate. The transmission shaft 111 can drive the drive gear 112 to rotate. The transmission gear 110 can reduce the output speed and output torque of the transmission shaft 111. In this way, when the steam cannot drive the turbine 114 to rotate, the impeller 113 can be driven to rotate with a small wheel circumferential force first, and then the turbine 114 can be driven to rotate through the generator shaft 15, thereby avoiding the turbine 114 from stopping.
