Device for improving heat exchanging effect of water cooling type cooler

Abstract

The invention discloses a device for improving the heat exchange effect of a water-cooled cooler. The cooling water inlet of the water-cooled cooler is connected with a reverse discharge pipe, and a reverse discharge valve is installed on the reverse discharge pipe. The cooling water outlet of the water-cooled cooler There is also a gas filling pipeline connected to the gas filling pipeline, and a gas filling valve is installed on the gas filling pipeline. The device also includes an air source storage tank, a pressure gauge is installed on the air source storage tank, the air source storage tank is connected with a supplementary air source through an air supply pipeline, and a self-adjusting valve is installed on the air supply pipeline. When in use, close the water inlet valve at the cooling water inlet of the water cooler, open the reverse discharge valve, then open the gas filling valve, and feed the gas through the gas filling pipe. The gas and water are mixed in the water cooler and flow in reverse direction to remove the adhesion to the inner wall of the water cooler. , The slimy dirt on the outer wall of the heat exchange tube is discharged out of the system through the reverse discharge pipe to ensure the heat exchange effect of the water cooler. By setting the self-adjusting opening, the pressure of the aerated buffer tank is guaranteed to be higher than the cooling water pressure.

Description

technical field [0001] The invention belongs to the technical field of heat exchange, and in particular relates to a device for improving the heat exchange effect of a water-cooled cooler. Background technique [0002] Water-cooled coolers are the most commonly used heat exchange equipment in chemical production plants. The water-cooled cooler uses cooling water and heat exchange medium to exchange heat on the inner partition wall of the heat exchanger to ensure that the temperature of the cooled medium reaches the process conditions. The most commonly used cooling water is circulating water. Due to the slow flow rate in the water cooler, slime and dirt are easily attached to the tube wall of the heat exchanger, resulting in poor heat transfer and reduced heat exchange efficiency, which affects the normal operation of the device. Contents of the invention [0003] The invention provides a device for improving the heat exchange effect of a water-cooled cooler. By changing ...
