Description

Technical Field

[0001] This utility model relates to the field of cleaning technology for liquid coolers, specifically to a cleaning device for liquid coolers. Background Technology

[0002] The desulfurization liquid cooler for coke oven gas in coking plants uses sulfur foam from the top of the regeneration tower to flow into the sulfur foam tank by gravity. The foam is then pumped to the sulfur melting kettle for heating and melting. The liquid flows into the clear liquid tank, is cooled by the clear liquid cooler, and then sent to the reaction tank. The working principle is that the plate heat exchanger introduces two fluids into different sides of the plate group, allowing the two fluids to flow relative to each other through the plate group, thus achieving heat transfer.

[0003] After a period of operation, impurities in the liquid cooler can easily clog it, reducing the heat exchange area and decreasing the cooling effect. The internal channels of the cooler are also prone to fouling (such as scale, oil, and organic matter buildup) due to the deposition of impurities and temperature changes. If not cleaned promptly, this can lead to decreased heat exchange efficiency (fouling thermal resistance can reduce efficiency by 20%-40%), increased energy consumption (15%-25%), and in severe cases, pipe blockage, localized overheating, and other malfunctions, causing the desulfurization liquid temperature to rise and affecting desulfurization efficiency. Therefore, we propose a cleaning device for the liquid cooler. Utility Model Content

[0027] Working principle: For this type of cleaning device for liquid coolers, when the device is in operation, the steam cleaning shovel 11 is first inserted into the cold side of the liquid cooler through the pre-welded handhole. The steam generator 1 is then started, and steam flows sequentially through the steam pipe 2, the hose 3, and the telescopic pipe 9, finally spraying out from the steam hole 14 on the baffle 13 at the front end of the steam cleaning shovel 11. This directly heats the cooler plates, causing the solid sulfur adhering to the flow channels to melt, liquefy, and flow out. At the same time, the operator holds the handle 7 on the operating rod 5 and can activate the electric telescopic rod 8. The telescopic end of the device is driven by the pipe clamp 10 to reciprocate the telescopic pipe 9 and the steam cleaning shovel 11 to scrape and clean stubborn deposits in a wider area. The protruding plate 12 at the front end of the steam cleaning shovel 11 can assist in scraping and collecting residues during this process. To stabilize the device, the fixing bracket 17 on the rod seat 6 can be rotated out of the groove 16 through the rotating shaft, and the entire device can be temporarily fixed to the external support point using its connecting hole 18. After the molten sulfur flows out and cools into blocks, it can be scraped out through the hand hole to complete the cleaning. Its advantages are flexible operation, thorough cleaning and high degree of automation.
