Description

Technical Field

[0001] The utility model relates to a quenching water device for an acetylene cracking furnace, belonging to the field of acetylene gas preparation. Background Art

[0002] In the acetylene production process, the cracking furnace is a core piece of equipment. Its stability and safety are directly related to the operational efficiency and product quality of the entire production line. During operation, the high-temperature cracking reaction in the cracking furnace generates a large amount of heat, which needs to be promptly removed by a cooling system to prevent overheating and ensure the continued progress of the cracking reaction.

[0003] However, in actual operation, heat exchangers are often clogged with impurities, which affects their cooling effect. This problem has become a key factor restricting the efficiency and quality of acetylene production. First, cracked gas usually contains a variety of impurities, such as dust, tar, catalyst residues, etc. When these impurities flow through the heat exchanger, they are easily deposited on the pipes or plates, gradually forming a blockage. As the degree of blockage increases, the flow area of ​​the heat exchanger will gradually decrease, resulting in obstructed heat transfer and a decrease in the cooling effect. This not only affects the cooling efficiency of the cracked gas, but may also cause risks such as equipment overheating and damage. Secondly, impurity blockage of the heat exchanger will also lead to increased energy consumption. Due to the decrease in cooling effect, in order to meet production needs, the flow rate of the cooling medium has to be increased or its temperature has to be lowered, which undoubtedly increases energy consumption. In addition, cleaning a clogged heat exchanger also requires a lot of manpower, material resources and time, further increasing production costs. In addition, impurity blockage may also have a negative impact on the service life of the heat exchanger. Long-term blockage will aggravate the corrosion and wear of the heat exchanger, reducing its performance and reliability. Once the heat exchanger fails, it will seriously affect the continuity and stability of acetylene production. Utility Model Content
