Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of water coolers, and more specifically relates to a water cooler flushing device. Background Art
[0002] The water cooler of the hydrogenation unit is used to cool the compressed exhaust gas at each stage of the new hydrogen compressor and the finished oil side line water cooler. The water cooler is used to cool the compressed gas, and the exhaust temperature at each stage has strict control indicators. Scaling of the water cooler tube bundle will cause the exhaust temperature to be too high. Excessive exhaust temperature will cause the compressor to interlock and shut down, causing fluctuations in the unit, endangering normal production, and even causing failures, posing a major safety hazard.
[0003] The water cooler of the hydrogenation unit is mainly used for inter-stage cooling of new hydrogen machines and cooling of oil products in each side line. After the water cooler has been used for a certain period of time, the water cooler tube bundle will be scaled. In order to maintain the cooling effect, it takes a certain amount of time to clean the scaled water cooler.
[0004] At present, the main method of cleaning water coolers is to isolate the water cooler from the use system, extract the tube bundle, and deliver it to the peripheral organization for cleaning. Therefore, the main equipment matched with the water cooler cannot continue to operate, affecting the operation of the equipment, and the cost of peripheral cleaning is high, which increases the production cost of the enterprise.
[0005] Therefore, how to develop a water cooler flushing device is a technical problem that technical personnel in this field urgently need to solve. Utility Model Content
[0006] In view of this, the utility model provides a water cooler flushing device.
[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0008] A water cooler flushing device comprises a water cooler, wherein the water cooler is connected with an inlet process medium pipeline and an outlet process medium pipeline;
[0009] The water cooler is provided with a circulating water inlet and a circulating water outlet, the circulating water inlet is connected to a circulating water inlet pipe, the circulating water outlet is connected to a circulating water outlet pipe, an inlet valve is installed on the circulating water inlet pipe, and an outlet valve is installed on the circulating water outlet pipe;
[0010] The pipeline between the circulating water inlet and the water inlet valve is connected with an air inlet pipeline, the air inlet pipeline is connected with a purification air source, and an air inlet valve is installed on the air inlet pipeline;
[0011] The pipeline between the circulating water outlet and the water outlet valve is connected with a sewage pipe, and a sewage valve is installed on the sewage pipe.
[0012] Advantages of the utility model:
[0013] The structure of the utility model is simpler. The cleaning method is to take out the water cooler for cleaning in a short time, which has a short time and does not affect the normal operation of the main process and equipment. The cleaning method is convenient and economical, and can ensure the long-term stable operation of the equipment.
[0014] The utility model can fully clean the scale and other impurities attached to the water cooler tube bundle, and the effect is quite remarkable. Through the actual operation inspection of the device and the inspection during the major overhaul, the cooling effect of the water cooler is greatly improved, the cleaning cost of the water cooler is significantly reduced, and the long-term operation of the compressor is effectively guaranteed.
