A graphite cooler for producing sulfur dioxide in the sugar industry

Abstract

One or more embodiments of the present specification provide a graphite cooler for producing sulfur dioxide in the sugar industry. By heating boiling water at 100°C in a boiling water tank, the first heat conductive plate and the second heat conductive plate respectively sense the temperature of the top of the boiling water tank and the cooling box and then transmit the temperature to the first thermal expansion block and the second thermal expansion block. When the temperature on the top of the cooling box is higher than 100°C, the second thermal expansion block has a relatively large expansion volume, which pushes the rotating disk to rotate, and drives the second connecting rod to move toward the detection cavity side through the first connecting rod, thereby linking the upper end of the third connecting rod to tilt toward the air adjustment shaft, so that the locking plate locks the locking gear, and the first and second air passing blades are fixed to achieve the closure of the air inlet, so that the sulfur dioxide in the cooling box continues to cool down until the temperature requirement is met, thereby avoiding temperature measurement and cooling again, saving manpower and material resources, and greatly reducing the waste of resources.

Description

Technical Field

[0001] One or more embodiments of the present specification relate to the technical field of sugar production, and in particular, to a graphite cooler for sulfur dioxide production in the sugar industry. Background Art

[0002] Sulfur dioxide is needed in sugar production. Edible sugar is processed by the nitrite method. The sugar processed by this method requires a large amount of sulfur dioxide to remove impurities in the raw materials such as silt and heavy metals. The required sulfur dioxide is produced by a sulfurization furnace. The temperature of the produced sulfur dioxide is very high, about 500°C, and it needs to be cooled to 100°C before use. The existing sulfur dioxide is cooled by cooling towers. The sulfur dioxide is passed upward from the bottom of the cooling tower and cooled by shower cooling.

[0003] However, the inventors have found that after the existing cooler cools sulfur dioxide, the temperature of sulfur dioxide cannot be accurately stabilized at 100°C. Due to poor cooling efficiency, the temperature is often much higher than 100°C, and it is necessary to measure the temperature again and cool it down, which consumes manpower and material resources and causes a waste of resources.

[0027] Based on the above purpose, one or more embodiments of this specification provide a graphite cooler 33 for producing sulfur dioxide in the sugar industry, characterized in that it includes:

[0028] A cooling box 1, a vertical air regulating cylinder 2 is fixed to one side wall of the cooling box 1, a rotatable air regulating shaft 3 is arranged in the vertical direction in the air regulating cylinder 2, an air outlet and an air inlet connected to the air regulating cylinder 2 are respectively opened on the side walls of the cooling box 1 near the upper and lower ends of the air regulating shaft 3, a horizontal first baffle and a second baffle are respectively arranged near the air outlet and the air inlet in the air regulating cylinder 2, a plurality of vertical first air passing blades 4 and a second air passing blade 5 adapted to the air regulating cylinder 2 are respectively fixed on the air regulating shaft 3 on the upper side of the first baffle and the lower side of the second baffle, the first air passing blade 4 and the second air passing blade 5 are respectively opened with two through holes facing the cooling box 1, and the top end of the air regulating shaft 3 passes through the cooling box 1 and is fixedly sleeved with a locking gear 6;

[0029] A boiling water tank 7 is fixed to the outer top of the cooling box 1, a heating plate 8 is arranged at the bottom of the boiling water tank 7, a detection cavity 9 is protruded upward from the top wall of the cooling box 1 on the side of the boiling water tank 7 opposite to the air regulating shaft 3, a first detection hole and a second detection hole are respectively opened on the opposite side walls of the boiling water tank 7 and the detection cavity 9, a first heat conducting block 10 and a second heat conducting block 11 are respectively fixed in the first detection hole and the second detection hole, and a first thermal expansion block 12 and a second thermal expansion block 13 are respectively fixed on the opposite sides of the first thermal conduction block 10 and the second thermal conduction block 11;

[0030] A rotating disc 14 is movably arranged in the center of the boiling water tank 7 and the detection cavity 9. A connecting block 15 is fixed to the front of the lower center of the rotating disc 14. The connecting block 15 is elastically connected to the first thermal expansion block 12 and the second thermal expansion block 13 on both sides through two elastic telescopic rods 16. A first connecting rod 17 is fixed to the top side of the rotating disc 14. The top of the first connecting rod 17 is rotatably connected to the second connecting rod 18. The other end of the second connecting rod 18 spans the boiling water tank 7 and is rotatably connected to the third connecting rod 19 on the other side of the air adjustment shaft 3. The bottom end of the third connecting rod 19 is rotatably connected to the top of the cooling box 1. A locking piece 20 corresponding to the position of the locking gear 6 is fixed on the third connecting rod 19.

[0031] One or more embodiments of the present specification provide a graphite cooler 33 for producing sulfur dioxide in the sugar industry. By heating boiling water at 100°C in a boiling water tank 7, the first heat conductive sheet and the second heat conductive sheet respectively sense the temperature of the boiling water tank 7 and the top of the cooling box 1 and then transmit it to the first thermal expansion block 12 and the second thermal expansion block 13. When the temperature at the top of the cooling box 1 is higher than 100°C, the second thermal expansion block 13 has a relatively large expansion volume, which drives the rotating disk 14 to rotate, and drives the second connecting rod 18 to move toward the detection cavity 9 through the first connecting rod 17, thereby linking the upper end of the third connecting rod 19 to tilt toward the air adjustment shaft 3, so that the positioning plate 2 0 locks the locking gear 6, and the first and second air passing blades 4 and 5 are fixed to close the air inlet, so that the sulfur dioxide in the cooling box 1 continues to cool down. When the temperature requirement is met, the volume of the second thermal expansion block 13 is reduced to the same as the volume of the first thermal expansion block 12, driving the locking piece 20 to disengage from the locking gear 6, and the sulfur dioxide in the cooling box 1 that meets the temperature requirement flows out, and the sulfur dioxide introduced into the air inlet continues to be cooled. The temperature of the sulfur dioxide after cooling is strictly controlled to be 100 degrees Celsius, avoiding the need to measure the temperature and cool down again, saving manpower and material resources, and greatly reducing the waste of resources.

[0032] When the sulfur dioxide temperature at the top of the cooling box 1 meets the requirement of being around 100°C, the volume of the second thermal expansion block 13 is reduced to the same as that of the first thermal expansion block 12. Under the balancing action of the two elastic telescopic rods 16, the rotating disk 14 rotates in the opposite direction, so that the connecting block 15 is relatively located at the lowest end, that is, on the vertical center line of the rotating disk 14. The second connecting rod 18 is driven by the first connecting rod 17 to move in the opposite direction of the detection cavity 9, and the top of the third connecting rod 19 is linked to move away from the air regulating shaft 3, so that the locking piece 20 is disengaged from the locking gear 6, so that the air regulating shaft 3 continues to rotate.

[0033] As an optional implementation, the first baffle and the second baffle are respectively provided with a first rotating hole and a second rotating hole adapted for the air regulating shaft 3, and the air regulating shaft 3 is rotatably disposed in the first rotating hole and the second rotating hole.

[0034] Optionally, the side wall of the air regulating cylinder 2 between the lower baffle and the second baffle is hollowed out to expand the cooling volume in the cooling box 1 .

The end of the air outlet is connected to the air outlet pipe 24, and the air outlet pipe 24 is provided with an air outlet fan blowing toward the outside.

[0037] When the sulfur dioxide is cooled, the air inlet fans 23 and the air outlet fans arranged on both sides blow the second fan blades and the first fan blades respectively and simultaneously, and blow the air regulating shaft 3 to rotate, and at the same time, the sulfur dioxide gas with a higher temperature generated in the vulcanization box 21 is blown into the cooling box 1 through the second fan blades, and the sulfur dioxide gas in the cooling box 1 that meets the temperature requirement is blown out of the cooling box 1 from the air outlet through the first fan blades, and the air outlet fans and the air inlet fans 23 arranged on both sides blow the air regulating shaft 3 to rotate in the same direction.

[0038] As an optional implementation, a heat-insulating support plate 26 is fixed to the bottom end of the boiling water tank 7 , and the bottom end of the heat-insulating support plate 26 is fixed to the top end of the cooling tank 1 .

[0039] Specifically, a water adding nozzle is provided at the top of the boiling water tank 7, and a water adding cap 27 is detachably screwed onto the water adding nozzle.

[0040] The heat-insulating support plate 26 fixes the boiling water tank 7 and isolates the boiling water in the boiling water tank 7 from the cooling tank 1 in temperature, thereby preventing the heat therebetween from affecting each other.

[0041] As an optional implementation, the first thermal expansion block 12 and the second thermal expansion block 13 are made of the same material and have the same shape and size.

[0042] The first thermal expansion block 12 and the second thermal expansion block 13 are made of the same material to ensure the same thermal expansion coefficient. The first thermal expansion block 12 and the second thermal expansion block 13 are equal in shape and size, so that when the temperatures of the boiling water box 7 and the detection cavity 9 sensed by the first heat conductive block 10 and the second heat conductive block 11 are the same, that is, the temperature of sulfur dioxide near the top of the cooling box 1 is around 100°C, the expansion widths between them are the same, and the rotating disk 14 can be kept relatively still, and the air regulating shaft 3 can rotate smoothly. When the temperatures of the boiling water box 7 and the detection cavity 9 sensed by the first heat conductive block 10 and the second heat conductive block 11 are different, that is, the temperature of sulfur dioxide near the top of the cooling box 1 is higher than 100°C, the expansion widths between them are different, and the air regulating shaft 3 is stuck through the linkage effect.

[0043] As an optional embodiment, the center of the rotating disk 14 is rotatably connected to a rotating shaft 28 , the end of the rotating shaft 28 is connected to a support rod 29 , and the bottom end of the support rod 29 is fixed to the top of the cooling box 1 .

[0044] As an optional embodiment, a graphite cooling pipe network 30 is provided in the cooling box 1, the top of the graphite cooling pipe network 30 is connected to a water inlet pipe, and the bottom end is connected to a water outlet pipe. The top of the water inlet pipe is also connected to a water spray pipe 31 that penetrates into the cooling box 1. The water spray pipe 31 in the cooling box 1 is connected to a plurality of downward atomizing nozzles 32. A water leakage port is opened at the bottom end of the cooling box 1, and an openable and closable water leakage pipe is connected to the water leakage port.

[0045] Specifically, the end of the water outlet pipe passes through the cooling box 1 and is connected to the cooler 33, the end of the leaking pipe is connected to the cooler 33, the cooler 33 is connected to the water storage tank 34, and the water storage tank 34 is connected to the water inlet pipe.

[0046] The flowing water in the graphite cooling pipe network 30 and the atomized water sprayed from the atomizing nozzle 32 cool the sulfur dioxide in the cooling box 1 at the same time, thereby improving the cooling efficiency. The cooled cooling water flows back to the cooler 33 for cooling and reuse, and after cooling, it is passed into the water storage tank 34 for reuse.
