Description

Technical Field

[0001] The invention relates to the technical field of desulfurized gypsum powder production, and in particular to a device for recovering and reusing waste heat from steam from a drying machine used in the production of desulfurized gypsum powder. Background Art

[0002] With the development of economy and the progress of society, energy conservation has become inevitable and a social consensus. Since saturated steam and heat transfer oil are used as heat sources in the production process of desulfurized gypsum powder, saturated steam is regarded as a clean heat source. The saturated steam pressure used in the production of desulfurized gypsum is usually 0.4-0.6MPa (temperature about 145℃) for dryer and 0.6-0.8MPa (temperature about 175℃) for fluidized bed furnace. After the saturated steam completes the heat exchange in the equipment, the pressure and temperature become low and condensed into water, which is collected in the condensate water tank through the return pipe and the steam trap to complete the heat recovery and reuse.

[0003] In the prior art, after the saturated steam completes the heat exchange in the equipment, the return water (steam) temperature is about 132°C and still contains a large amount of thermal energy. If it is directly returned to the condensate tank, it will cause a waste of thermal energy, making it impossible to fully utilize the saturated steam, resulting in a waste of energy and failing to meet the demand for effective use of thermal energy.

Since the sixth rotating rod 46 is located at one end of the outer wall outside the steam pipe 6 and the outer side wall of the rotating rod 18 are fixedly connected with the second sprocket 48, and a pair of second sprockets 48 are connected by a second chain 49, the rotation of the sixth rotating rod 46 drives the rotating rod 18 to rotate through the second sprocket 48 and the second chain 49, thereby reducing the pressure on the rotating rod 18 and the reciprocating rotating rod 15 to rotate, and when the rotating rod 18 rotates, the rotation of the rotating rod 18 will also drive the rotating shaft 13 to rotate through the first sprocket 20 and the first chain 21, thereby generating electricity, so that the device not only makes the rotation of the reciprocating rotating rod 15 easier and simpler, but also further improves the efficiency and effect of power generation of the device.

[0040] When the present invention is in use, the return water pressure of the drying machine body 4 and the boiling furnace body 3 is 0.2MPa and the temperature is 132°C, so that the drying machine body 4 and the boiling furnace body 3 transport the return water to the flash tank body 5 through the delivery pipe 2. When the return water enters the flash tank body 5, the return water pressure becomes smaller due to the increase in space, and a large amount of saturated steam is released. Under the influence of gravity, water gathers below the flash tank body 5. When the liquid level detector 9 detects that the water reaches a certain amount, the second return water valve is opened to transport the water to the condensate tank 10 for recovery and reuse, and the steam enters the steam injection device 7 through the steam pipe 6, and is reused along the gas supply pipe 8, so that the device can more effectively and fully utilize energy. Thereby, the demand for effective use of thermal energy is better met, and when water flows from the delivery pipe 2 into the flash tank body 5, because the upper part of a group of power generation plates 14 is located in the square shell 11, and the lower part of a group of power generation plates 14 is located in the delivery pipe 2, the flow of water will drive the power generation plates 14 located in the delivery pipe 2 to rotate, thereby driving the rotation shaft 13 to rotate, so that the rotation of the rotation shaft 13 drives the power generation mechanism in the power generation device 12 to generate electricity, so that the potential energy of the water flow is converted into electrical energy, so that the device can not only effectively recover steam, water and thermal energy, but also generate electricity through the flow of return water, and then use the generated electricity to operate the equipment, so that not only the energy is further effectively recycled and reused, but also the generation of the device can be reduced. The production processing cost is increased, and when the rotating shaft 13 rotates, because the other end of the outer wall of the rotating rod 18 and the outer side wall of the rotating shaft 13 are fixedly connected with the first sprocket 20, and the pair of first sprockets 20 are connected by the first chain 21, the rotation of the rotating shaft 13 drives the rotating rod 18 to rotate through the first sprocket 20 and the first chain 21, and the rotation of the rotating rod 18 drives the second bevel gear 19 to rotate. Since the second bevel gear 19 is meshed with the first bevel gear 17, the rotation of the second bevel gear 19 drives the reciprocating rotating rod 15 to rotate through the first bevel gear 17, and the rotation of the reciprocating rotating rod 15 drives the cleaning plate 16 to reciprocate, so that the cleaning plate 16 moves up and down to clean the inner side wall of the flash tank body 5, so that impurities or scale generated by the return water and steam, etc. The flash tank body 5 is cleaned by the cleaning plate 16, thereby ensuring the safety of the flash tank body 5 and making the flash tank body 5 not easily corroded, thereby increasing the service life of the flash tank body 5. When the steam flows to the steam pipe 6 through the top of the flash tank, the flow of steam will drive the power generation blades 44 to rotate through the airflow, so that the power generation blades 44 drive the fifth rotating rod 43 to rotate, thereby driving the eighth bevel gear 45 to rotate. Since the ninth bevel gear 47 and the eighth bevel gear 45 are meshed with each other, the rotation of the eighth bevel gear 45 drives the sixth rotating rod 46 to rotate through the ninth bevel gear 47. Since the outer wall end of the sixth rotating rod 46 is located outside the steam pipe 6 and the outer side wall of the rotating rod 18 are fixedly connected with a second sprocket 48, and a pair of second sprockets 48 are connected by a second chain 49.The rotation of the sixth rotating rod 46 drives the rotating rod 18 to rotate through the second sprocket 48 and the second chain 49, thereby reducing the pressure on the rotating rod 18 and the reciprocating rotating rod 15 to rotate, and when the rotating rod 18 rotates, the rotation of the rotating rod 18 will also drive the rotating shaft 13 to rotate through the first sprocket 20 and the first chain 21, so as to generate electricity, so that the device not only makes the rotation of the reciprocating rotating rod 15 easier and simpler, but also further improves the efficiency and effect of power generation of the device, and when the reciprocating rotating rod 15 rotates, because the outer wall of the reciprocating rotating rod 15 is provided with a sliding groove 22 and the inner wall of the third gear 23 is fixedly connected with a slider 24, and the outer wall of the slider 24 is slidably connected to the inner wall of the sliding groove 22, the rotation of the reciprocating rotating rod 15 is The slider 24 drives the third gear 23 to rotate. Since the bottom end of the outer wall of the third gear 23 is rotatably connected to the top end of the outer wall of the cleaning plate 16, the third gear 23 can move up and down with the cleaning plate 16, and while moving up and down, it rotates through the reciprocating rod 15. The rotation of the third gear 23 drives the fourth gear 26 to rotate. The rotation of the fourth gear 26 drives the fifth gear 28 to rotate. The rotation of the fifth gear 28 drives the first rotating rod 27 and the rotating plate 29 to rotate. The rotation of the rotating plate 29 drives the square block 31 to rotate, so that the square block 31 cleans the inner side wall of the flash tank body 5 when rotating. When the square block 31 encounters the reciprocating rod 15, the square block 31 will shrink because one end of the outer wall of the square block 31 located outside the square groove 30 is in an isosceles trapezoidal shape. When the reciprocating rotating rod 15 leaves its position, it will pop out due to the elastic force of the first spring, so that the cleaning plate 16 cooperates with the cleaning of the square block 31, so that the inner wall of the flash tank body 5 is cleaned more thoroughly, thereby further ensuring the internal environment of the flash tank body 5, and when the rotating plate 29 rotates, the rotation of the rotating plate 29 drives the second rotating rod 34, the sixth gear 35 and the auxiliary plate 36 to rotate around the center of the first rotating rod 27, because the inner side wall of the cleaning plate 16 is fixedly connected with the annular rack 32 and the sixth gear 35 is meshed with the annular rack 32, so that the annular rack 32 is in a stationary state, and the sixth gear 35 will rotate along the inner side wall of the annular rack 32, so that the sixth gear 35 rotates around the inner side wall of the annular rack 32, and at the same time, due to the static The annular rack 32 in the stopped state rotates, so that the rotation of the sixth gear 35 drives the second rotating rod 34 and a group of auxiliary plates 36 to rotate, so that when the rotating plate 29 moves to the bottom end of the inner wall of the flash tank body 5, the multiple groups of auxiliary plates 36 can cooperate with the rotation of the rotating plate 29 to clean the bottom end of the inner wall of the flash tank body 5, so that the bottom end of the inner wall of the flash tank body 5 is also cleaned, so that the cleaning range of the device is increased, which is more practical, and when the auxiliary plate 36 moves to the bottom end of the inner wall of the flash tank body 5, the auxiliary plate 36 rotates to clean the bottom end of the inner wall of the flash tank body 5, and the rotation of the auxiliary plate 36 also drives the guide block 38 to rotate, so that when the guide block 38 encounters impurities, the impurities will enter the second through groove 37 along the inclined surface of the guide block 38,Then, the impurities enter the collecting shell 39 through the second through groove 37, so that the device can not only clean the inner wall of the flash tank body 5, but also collect the impurities accumulated at the bottom of the inner wall of the flash tank body 5, so that the impurities are not easy to accumulate, thereby ensuring the purity of the recovered water, and preventing the impurities from clogging the flash tank body 5, causing the water to be unable to flow, and by collecting the impurities, the impurities are not easy to pollute or corrode the water and the flash tank body 5, and the internal environment of the flash tank body 5 is ensured, and when the impurities are collected in the collecting shell 39, a group of filtering holes 40 are opened at the bottom of the outer wall of the collecting shell 39, so that the water will flow out of the collecting shell 39 through the filtering holes 40, so that the collecting shell 3 9 will only recycle solid impurities, but not water, so that water is not easily wasted, and the collection shell 39 can collect more impurities. When the auxiliary plate 36 drives the guide block 38 to rotate to recycle impurities, when the guide block 38 rotates to the position of the assisting plate 42, through the structure of the guide block 38 and the assisting plate 42, the guide block 38 will squeeze the assisting plate 42 when it encounters the assisting plate 42, so that the assisting plate 42 will move up along the inclined surface of the guide block 38, so that when the guide block 38 drives the impurities to encounter the assisting plate 42, the impurities will be collected faster and more thoroughly with the help of the assisting plate 42 and the guide block 38, thereby further improving the collection efficiency and collection effect of the device for impurities.
