Problems solved by technology
However, in some chemical production, the air flow rate is particularly large, the resistance drop requirement is small, and the cooling water flow rate is very small. The usual shell-and-tube cooler has a small gas side cross-section, a large resistance drop, and is easy to block, which cannot meet the requirements at all. production needs, so how to complete the heat exchange between the two media has become a difficult problem
For this reason, the industry has developed a gas cooler. Although this kind of gas cooler has a better cooling effect, due to the large deflection of the heat exchange tube during operation, and the large flow rate of the gas to be cooled, the heat exchange tube vibrates. The damage causes the entire equipment to be out of service, and the temperature of the cooling gas is very high, and the shell of the cooler body itself expands greatly due to thermal stress. In this way, due to the influence of temperature difference stress, the shell expands due to heat and damages the equipment.

The coal gas cooler comprises a base, a movable support mechanism, and a cooler body moved freely on base to eliminate thermal stress of shell for temperature difference expansion. Wherein, the cooler body comprises pipe plate, and heat exchange pipes connected to a plurality of water tanks and formed long come-and-go flow path for cooling water finishing heat exchange; arranging one or more support plates to prevent large deflection and avoid vibration or resonance and prolong service life. This invention has well heat exchange effect.
Description
technical field [0001] The invention relates to a gas cooler, in particular to a cooler with multiple tubes, long tube channels, large shell side flow section and movable cooler body. Background technique [0002] Shell-and-tube cooler is a commonly used heat exchange device. It usually consists of tube sheets at both ends and a cylinder in the middle. The tube sheet and heat exchange tubes form internal parts. The fluid flows in the tube box and the heat exchange tube, and the low-temperature fluid flows in the shell side outside the heat exchange tube, and the heat exchange is carried out through the heat exchange on the wall of the heat exchange tube. However, in some chemical production, the air flow rate is particularly large, the resistance drop requirement is small, and the cooling water flow rate is very small. The usual shell-and-tube cooler has a small gas side cross-section, a large resistance drop, and is easy to block, which cannot meet the requirements at all. ...
