Description

Technical Field

[0001] The utility model relates to the technical field of cooler cleaning, in particular to a mobile tubular cooler cleaning system. Background Art

[0002] The tube cooler, also called shell and tube cooler, is divided into tube side and shell side. The liquid flowing in the tube is the tube side, and the liquid flowing outside the tube is the shell side. The wall of the tube bundle is the heat transfer surface. When the temperature difference between the tube bundle and the shell exceeds 50°C, appropriate temperature compensation measures are taken to eliminate or reduce thermal stress. Generally, water cooling is dominant. After using the tube cooler for a period of time, workers need to clean it. Generally, the tube cooler is disassembled first, and then the workers clean the parts of the cooler with a cleaning brush. This method is time-consuming and labor-intensive.

As the inner diameter of the nozzle part continues to decrease, the spraying speed of the cleaning liquid swirl mixed with countless small bubbles is accelerated to become a high-speed cleaning liquid swirl mixed with countless small bubbles. The high-speed gas-liquid mixed swirls on both sides collide, and the countless small bubbles are again broken up, cut, and differentiated into smaller bubbles, and finally sprayed to the inner sides of the shell-and-tube cooler through the second outer spray hole 33. Since the lower end of the second bubble cleaning inner shell 24 is an inverted cone structure, the spraying speed of the high-speed gas-liquid mixed swirl colliding will reach a higher level.

[0097] When the high-speed cleaning fluid and countless tiny bubbles come into contact with the interior of the shell-and-tube cooler, the impact force of the cleaning fluid and the energy of the rupture of countless tiny bubbles have an impact and cleaning effect on various parts of the interior of the shell-and-tube cooler, which can remove the dirt on the inner wall of the shell-and-tube cooler and achieve better cleaning effect.

[0098] In the second stage, the water pump on the lower liquid outlet pipe 11 starts working and the valve is opened, and the cleaning liquid is respectively transported to the first rotary washer and the second rotary washer through the first outer tube 4 and the second outer tube 6; the first motor starts working and the second motor starts working, the output shaft of the first motor drives the first outer shell 22 to rotate, and the output shaft of the second motor drives the second outer shell 31 to rotate.

[0099] In the first rotary washer, the cleaning liquid is transported to the outer liquid flow space 32 and sprayed out from the plurality of second outer liquid spray holes 33; in the first rotary washer, the cleaning liquid is transported to the outer liquid flow space 32 and sprayed out from the plurality of second outer liquid spray holes 33.

[0100] The first rotary washer or the cleaning liquid sprayed from the first rotary washer washes the inside of the shell-and-tube cooler and removes bubbles remaining inside the shell-and-tube cooler.

[0101] The first stage cleaning and the second stage cleaning are performed alternately, so that the first stage cleaning is performed on both sides of the interior of the shell-and-tube cooler respectively. After the first stage cleaning is completed, the second stage cleaning is immediately performed, and the cycle is repeated.

[0102] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
