Dual turbulent spiral forced heat exchanging and automatic descaling device

Abstract

A device of intensified heat exchange and automatic descaling in dual turbulation screw type includes screw tube, screw tie, connection rod, fixing frame and rotary rod as small end of the rotary rod sheathed into hole at exle liquid input end of fixing frame to form rotation cooperation, end point of small end of the rotary rod to be connected by connecting piece in hinge joint with end point of one end of the screw tie, the screw tube with external circle and intermediate internal hole being all the straight tube of screw shape and two end parts being round tube shape to be set on external cylindrical surface of cylinder shape end of the fixing frame. The present invention uses technique of combining the screw tube with the screw tie to bring the screw tie to rotate by flowing of fluid in the screw tube to make no fouling within the tube and heat conduction face can carry on desaling automatically under the dual turbulation of the screw tube and tie to enhance more the efficiency of heat exchange.

Description

technical field [0001] The invention relates to a cleaning device using self-flowing liquid, which is a double-turbulence spiral type enhanced heat exchange and automatic descaling device. Background technique [0002] Heat exchange equipment is a kind of equipment that obtains the required process requirements or products through cold and heat exchange, but the dirt and scale on the heat transfer surface will deteriorate the heat transfer and directly cause energy waste, which will increase the area of ​​heat transfer equipment and increase the investment cost. Significantly increased, periodic production shutdown and cleaning affect output, quality and cost, and require considerable cleaning costs. Severe fouling causes increased liquid delivery resistance, resulting in corrosion under the scale, and even blockage. [0003] At present, there are mainly reciprocating mechanical methods, rotary mechanical methods, deformation cleaning methods, vibra...

AI Technical Summary

Problems solved by technology

Among them, the reciprocating mechanical method and the rotary mechanical method are equipped with complex mechanical devices, which require additional energy, which will cause great wear and tear on the heat exchange tubes, and the life of the main equipment will be greatly shortened; the deformation cleaning method uses heat from different materials or media. The principle of different expansion and contraction coefficients makes the scales deform and fall off. However, due to the frequent thermal expansion and contraction, the heat exchange tubes are also deformed at the same time, which will cause cracked tubes to leak. The spiral bond method uses fluid kinetic energy to automat
