Description

Technical Field

[0001] The utility model relates to an acetylene generator, in particular to the structure of the acetylene generator. Background Art

[0002] An acetylene generator is a device used to produce acetylene gas by chemically reacting water and calcium carbide (CaC2). A reaction plate and a stirring device are provided in the acetylene generator. After the material enters the generator, it falls onto the reaction plate, and water is sprayed onto the material through a spray pipe on the upper part of the generator, causing the calcium carbide to undergo a hydrolysis reaction to produce acetylene gas. In order to increase the reaction speed and the utilization rate of calcium carbide, the calcium carbide material on the reaction plate is stirred by the rake teeth provided on the stirring device.

[0003] In acetylene production, in order to save water resources, washing water from a washing tower for washing acetylene gas is usually used as reaction water. Acetylene gas washing water usually contains solid impurities, which can easily cause the water outlet of the nozzle to be blocked, resulting in a decrease in the spray flow rate and a decrease in the production capacity of the generator. Frequent shutdowns are required to replace and clean the nozzles, which not only wastes acetylene gas and increases production costs, but also affects normal production.

[0004] In addition, when adding calcium carbide to the acetylene generator, the calcium carbide falls into the reaction chamber from the feed port, and the collision of the calcium carbide with the reaction plate will produce dust. The long-term accumulation of dust will also block the water outlet of the nozzle. The dust enters the washing tower with the acetylene gas, which will cause an increase in impurities in the washing water and increase the frequency of blockage of the water outlet of the nozzle. In addition, the collision of calcium carbide with the reaction plate and the stirring device will also cause damage to the equipment and reduce the service life of the equipment.

[0005] The utility model aims to solve the problem that the water outlet hole of the nozzle is easily blocked due to the large amount of impurities in the reaction water during acetylene production. Utility Model Content

The reaction water is filtered by the filter 6 and sprayed on the material on the reaction plate 16 through the nozzle 32 for reaction. The acetylene gas generated by the reaction is discharged from the exhaust port 13, and the calcium carbide slag is regularly discharged from the slag discharge port 14. When the water outlet of the nozzle 32 is blocked, the flushing pump 41 is connected to the flushing water pipeline, the flushing pump 41 is turned on, and the water outlet of the nozzle 32 is high-pressure flushed by high-pressure water to restore the water outlet of the nozzle. The nozzle is unobstructed, and the flushing pump 41 is turned off to continue the acetylene gas production.

[0009] The utility model provides a filter 6 on the spray device 3, through which the larger particles of impurities in the reaction water can be filtered, thereby reducing the frequency of clogging of the water outlet of the nozzle 32. By providing a flushing device 4, when the water outlet of the nozzle 32 is clogged, the flushing pump 41 is turned on to perform high-pressure flushing on the water outlet of the nozzle 32, flush out the clogged material, and restore the water outlet of the nozzle 32 to be unobstructed. The utility model can solve the problem that the water outlet of the nozzle 32 is easily clogged due to the large amount of impurities in the reaction water in acetylene production.

[0035] The stirring motor 21 drives the stirring rod 22 to rotate, thereby driving the rake arm 23 to rotate. The rake teeth 24 on the rake arm 23 can stir and scrape the material on the reaction plate 16, so that the material on the reaction plate 16 is evenly spread and the reaction rate is improved.

[0036] The spray device 3 includes a spray pipe 31 , a filter 6 , a distribution pipe 33 and a spray head 32 . The spray pipe 31 is arranged on the tank body 1 , with a first end located outside the tank body 1 and a second end extending through the tank body 1 into the tank body 1 .

[0037] The distribution pipe 33 is annular and horizontally arranged in the tank body 1 , and is fixedly connected to the second end of the spray pipe 31 and communicated with the inside.

[0042] The distribution hopper 5 is arranged in a spiral shape, so that the material can slide along the inner wall of the distribution hopper 5 to the reaction plate 16 when falling, thereby reducing the falling speed of the material. When the material falls from the distribution hopper 5 to the buffer plate 53, the material is buffered by the elastic force of the spring 52, thereby further reducing the speed at which the material falls to the reaction plate 16, reducing dust generation, reducing dust in acetylene gas, thereby reducing the impurity content in the reaction water, and reducing the clogging frequency of the nozzle 32.

[0046] like Figure 4 and Figure 5 As shown, the filter 6 includes a shell 61 and a filter plate 64. The upper part of the shell 61 is open, and the opening is sealed by a top cover 62. A sewage outlet 68 is provided at the bottom of the shell 61, and a filter chamber 69 is formed inside. Vertically extending mounting grooves 63 matching the filter plate 64 are provided on opposite sides of the inner wall of the shell 61.

[0047] Vertically extending mounting grooves 63 matching the filter plate 64 are provided on opposite sides of the inner wall of the shell 61, wherein matching means that the width of the mounting groove 63 is the same as the thickness of the filter plate 64, and the height of the mounting groove 63 is the same as the height of the filter plate 64, so that the filter plate 64 can be slidably inserted into the mounting groove 63 to fix the filter plate 64.

[0048] The water inlet 65 and the water outlet 66 are arranged on the side walls of the housing 61 opposite to each other, and the flushing port 67 is arranged on the top cover 62 .

The impurities are blocked by the filter plate 64 and remain in the water inlet cavity 691, and are discharged from the slag discharge port 14 at regular intervals, thereby preventing the impurities from entering the nozzle 32 and clogging the water outlet of the nozzle 32. When a large number of impurities adhere to the filter plate 64, the filter plate 64 is flushed with high pressure by the flushing device 4, thereby removing the impurities adhered to the filter plate 64 and restoring the filtering capacity of the filter plate 64.

[0055] The utility model provides a filter 6 on the spray device 3, through which larger particles of impurities in the reaction water can be filtered, thereby reducing the frequency of blockage of the water outlet of the nozzle 32. By providing a flushing device 4, when the water outlet of the nozzle 32 is blocked, the flushing pump 41 is turned on to perform high-pressure flushing on the water outlet of the nozzle 32, flush out the blockage, and restore the water outlet of the nozzle 32 to be unobstructed.

[0056] The distribution hopper 5 is arranged in a spiral shape, so that the material can slide along the inner wall of the distribution hopper 5 to the reaction plate 16 when falling, thereby reducing the falling speed of the material. When the material falls from the distribution hopper 5 to the buffer plate 53, the material is buffered by the elastic force of the spring 52, which can reduce the generation of dust and the dust in the acetylene gas, thereby reducing the impurity content in the reaction water and reducing the clogging frequency of the nozzle 32.
