Technical Field

[0001] The utility model relates to a drainage system, in particular to an automatic drainage system for an acetylene water ring compressor. Background Art

[0002] During the post-monocrystalline silicon production cleaning process, acetylene water is primarily used as the cleaning liquid. This circulating acetylene water cleans the production equipment. After cleaning, the acetylene water is drained directly into the ditch by a compressor and a separation cylinder. It then flows automatically into the slurry pool due to the terrain difference. Each compressor discharges 0.1 tons of dissolved acetylene water each time, 72 times per day. With two compressors in operation, approximately 432 cubic meters of dissolved acetylene water are discharged each month.

[0003] Among them, one of the main raw materials for the production of acetylene water is calcium carbide, and the monthly discharge of a large amount of dissolved acetylene water will result in a large amount of calcium carbide waste. Utility Model Content

Therefore, the drawings and description are to be regarded as illustrative in nature and not restrictive.

[0030] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0031] Example:

[0032] See also Figure 1 This embodiment discloses an automatic drainage system for an acetylene water ring compressor, including a compressor body 100, a wastewater collection tank 200, a wastewater pump 300 and a dust removal tower 400.

[0033] Specifically, the compressor body 100 has an acetylene water input pipe 101, an acetylene gas discharge pipe 102, an acetylene water output pipe 103 and a desalted water input pipe 104, wherein the acetylene water input pipe 101 is connected to the output end of the cleaning equipment, the acetylene gas discharge pipe 102 is used to discharge the acetylene gas after the acetylene water is initially separated in the compressor body 100, the desalted water input pipe 104 is used to transport desalted water into the compressor body 100, mainly for removing various salts in the acetylene water, and the acetylene water output pipe 103 is mainly used to output pure acetylene water.

[0034] A connection portion is provided at the top of the wastewater collecting tank 200 and is connected to the acetylene water output pipe 103. Since each compressor body 100 discharges 0.1 tons of water each time and discharges 72 times a day, the acetylene water discharged from the compressor body 100 can be collected and temporarily stored through the wastewater collecting tank 200.

[0035] The suction end of the wastewater pump 300 is connected to the bottom of the wastewater collection tank 200, and the discharge end of the wastewater pump 300 is set on the dust removal tower 400. When the acetylene water in the wastewater collection tank 200 reaches a certain amount, the wastewater pump 300 can be started to pump the acetylene water into the dust removal tower 400.

[0036] A desorption pipe is provided on the discharge end of the wastewater pump 300 , and the desorption pipe exchanges heat with the circulating liquid pipe of the dust removal tower 400 .

[0037] In this embodiment, after the wastewater pump 300 pumps the acetylene water into the dust removal tower 400, since the temperature of the circulating liquid in the dust removal tower 400 is between 90°C and 95°C, the acetylene water can exchange heat with the circulating liquid in the dust removal tower 400, thereby utilizing the temperature difference to decompose the acetylene gas dissolved in the water, thereby reducing the loss of acetylene gas.

[0038] Through this technical solution, acetylene gas can be recycled after analysis, thereby achieving the purpose of recycling acetylene water and reducing the use of calcium carbide.

[0039] In one specific embodiment:

[0040] The compressor body 100 includes a pressurizer 105, a separation cylinder 106, and a storage tank 107. The input end of the pressurizer 105 is connected to the acetylene water input pipe 101, and the output end of the pressurizer 105 is connected to the input end of the separation cylinder 106. Meanwhile, the output end of the pressurizer 105 is connected to the side of the storage tank 107.

[0041] The top of the storage tank 107 is connected to the above-mentioned acetylene gas discharge pipeline 102, the side of the storage tank 107 is also connected to the above-mentioned desalted water input pipeline 104, and the bottom of the storage tank 107 is provided with the above-mentioned acetylene water output pipeline 103.

[0042] In this embodiment, the pressure of the entire system is increased by the pressurizer 105 so that the acetylene water can smoothly enter the wastewater collection tank 200. In addition, the storage tank 107 is provided to facilitate the mixing of desalted water and acetylene water. The function of the separation cylinder 106 is to separate part of the acetylene gas in the acetylene water.

[0043] Preferably, pressurizer 105 is provided with a gas conduit 108 connected to storage tank 107, and a liquid conduit 109 connected to acetylene water output conduit 103. Within pressurizer 105, the pressure of the acetylene water increases, and a small amount of acetylene gas is separated and can enter storage tank 107 directly through gas conduit 108. Alternatively, when a large amount of acetylene water is delivered via acetylene water input conduit 101, it can be directly delivered to wastewater collection tank 200 via liquid conduit 109.

[0044] In another preferred embodiment, a pressure detector 110 is provided between the pressurizer 105 and the separation cylinder 106 . The pressure detector 110 is provided between the two to detect the pressure value output by the pressurizer 105 .

[0045] In another specific embodiment:

[0046] A shut-off valve 111 is provided on the acetylene water output pipe 103. Because the solenoid valve has a back pressure of 300-400 kPa, and the top of the wastewater collection tank 200 is 3 meters high, the separation cylinder 106 in the compressor body 100 requires a minimum pressure of 70 kPa to drain water to the wastewater collection tank 200. Therefore, the solenoid valve cannot meet the requirement. Therefore, the shut-off valve 111 is used to solve the back pressure problem.

[0047] In another specific embodiment:

[0048] A bridge pipe 112 is provided between the acetylene water input pipeline 101 and the acetylene gas exhaust pipeline 102. The bridge pipe 112 is provided with a normally closed valve. By providing the bridge pipe 112, when the fluid transported by the acetylene water input pipeline 101 is pure gas, it can directly enter the acetylene gas exhaust pipeline 102 through the bridge pipe 112 for recycling.

[0049] In another specific embodiment:

[0050] A backup pump 301 is provided between the wastewater collection tank 200 and the dust removal tower 400. The backup pump 301 is arranged in parallel with the wastewater pump 300. When the wastewater pump 300 fails, the backup pump 301 can be used to replace the wastewater pump 300.

[0051] In another specific embodiment:

[0052] A liquid level detector is provided in the wastewater collection tank 200, and the detector is also electrically connected to the wastewater pump 300 or the backup pump 301, so that the wastewater pump 300 or the backup pump 301 can be automatically started when the liquid level in the wastewater collection tank 200 reaches a certain position.

[0053] In another specific embodiment:

[0054] A check valve 113 is provided on the acetylene water input pipe 101 to prevent the acetylene water from flowing back.

[0055] The above-described embodiments merely represent specific implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
