Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of acetylene production, and is a cleaning device for an acetylene mud washer. Background Art
[0002] Acetylene is commonly known as wind coal and calcium carbide gas, which is usually obtained by reacting calcium carbide with water. Since the generated crude acetylene gas contains dust and is at a high temperature, a mud washing device is needed to spray the acetylene gas to reduce the temperature of the acetylene gas and reduce the dust in the acetylene gas, ensuring the stable operation of subsequent equipment and extending the service life of subsequent equipment. In the existing acetylene production process, the 85°C acetylene gas from the generator enters the positive water seal after being cleaned and cooled by the mud washer, and then enters the compressor through the cooling tower 1 for cleaning and cooling before being sent to acetylene purification. Since the crude acetylene gas from the generator contains a large amount of calcium hydroxide impurities, the sieve plate of the mud washer becomes fouled, resulting in an increase in the pressure of the generator body and affecting normal production; in severe cases, the bell of the gas holder may be damaged and acetylene gas may leak; in addition, when the generator operates at a high pressure, the waist drum ring is damaged and acetylene gas leaks, posing a great safety hazard.

A first flushing pipeline 16 is fixedly communicated between the discharging end of the cooling tower 6 and the flushing nozzle 8.
[0018] According to actual needs, the above acetylene mud washer cleaning device can be further optimized and / or improved as follows:
[0019] Embodiment 2: The difference from Embodiment 1 is that as shown in the appendix Figure 1 A coolant pipeline 17 is fixedly communicated between the first flushing pipeline 16 and the second feeding end of the generator 1.
[0020] Embodiment 3: The difference from Embodiments 1 to 2 is that as shown in the appendix Figure 1 A slurry discharge pipeline 18 is fixedly connected between the bottom discharging end of the generator 1 and the feeding end of a slurry tank 20.
[0021] Embodiment 4: The difference from Embodiments 1 to 3 is that as shown in the appendix Figure 1 A second flushing pipeline 19 is fixedly communicated between the first flushing pipeline 16 between the coolant pipeline 17 and the flushing nozzle 8 and the upper feeding end of the mud washer 2.

[0023] According to needs, valves and instruments for normal operation are fixedly installed on each pipeline of the acetylene mud washer cleaning device.
[0024] In use, the carbide material from the upstream crushing process enters the generator 1 and produces crude acetylene gas. The crude acetylene gas enters the mud washer 2, and after being cleaned in the mud washer 2, it enters the downstream acetylene purification process. The mixed liquid of the cooling circulating liquid and the reacted slag in the generator 1 is discharged from the generator 1 into the slurry high-level tank 3, where it is precipitated and separated into supernatant liquid in the sedimentation tank 4 and the clear liquid tank 5. The supernatant liquid from the clear liquid tank 5 is sent to the cooling tower 6 by the first delivery pump 21, and after being cooled down, the cooling liquid is further sent to the generator 1 and the mud washer 2 respectively through the second delivery pump 22. In the mud washer 2, the cooling liquid flushes the sieve plate 7 in the mud washer 2 upward through the flushing nozzle 8. Since the temperature of the cooling liquid is low, it will not cause the temperature of the mud washer to rise sharply after entering the mud washer 2, and the pressure of the cooling liquid is 0.5 Mpa, with a large flushing force on the sieve plate 7, which can more effectively remove the calcium hydroxide attachments on the sieve plate 7, extend the service life of the mud washer 2, and reduce the pressure fluctuation of the generator 1.
[0025] In summary, the utility model utilizes the cooling circulating liquid of the acetylene generator to realize the flushing of the sieve plate in the mud washer, extends the service life and cleaning cycle of the mud washer, ensures the safe and stable operation of the generator; avoids the problem of the generator pressure increase caused by the blockage of the sieve holes; reduces the cleaning frequency of the mud washer blockage personnel from the source, reduces the labor cost, and solves the potential safety hazard.
[0026] The above technical features constitute the embodiments of the utility model, which have strong adaptability and implementation effects. Non-essential technical features can be added or reduced according to actual needs to meet the requirements of different situations.
