Problems solved by technology

But its disadvantage is that because the volume of the container is much larger than that of the coiled tube, the α of the fluid outside the tube is smaller, so the total heat transfer coefficient K value is also smaller

Embodiment Construction

[0015] A serpentine heat exchanger is composed of an inlet pipe 1, an outlet pipe 2, a stirring rod 3, a stirring blade 4, and a serpentine heat exchange pipe 5; the upper end of the serpentine heat exchange pipe 5 is connected to the inlet pipe 1, The lower section is connected to the outlet pipe 2, and the annular space formed inside the serpentine heat exchange tube 5 is nested with the stirring rod 3, and the stirring rod 3 has a stirring blade 4 on it.

[0016] The inlet pipe 1, outlet pipe 2 and serpentine heat exchange pipe 5 are made of carbon fiber composite material.

[0017] The stirring rod 3 and the stirring blade 4 are made of carbon fiber composite material.

[0018] When working, the stirring rod 3 at the bottom of the serpentine heat exchanger immersed in the container 6 rotates, driving the stirring blade 4 to rotate, and the cooling liquid is passed into the inlet pipe 1, and the cooling liquid passes through the inlet pipe 1 and the serpentine heat exchange...

Abstract

The invention relates to the field of chemical equipment and particularly relates to a serpentine type heat exchanger. The upper end of a serpentine type heat exchange tube is connected with an inlet tube, and the lower end of the serpentine type heat exchange tube is connected with an outlet tube; a stirring rod is nested in an annular space formed in the serpentine type heat exchange tube; and the stirring rod is provided with a stirring blade. The serpentine type heat exchanger is easy to construct, easy to manufacture and good in heat transfer effect and can be heated uniformly; the serpentine type structure can bear high pressure and is usually used for cooling high pressure fluids; the serpentine type heat exchanger is large in heat transfer coefficient, small in fouling resistance, compact in structure and easy to maintain; and the adopted stirring device is a detachable structure nested in the heat exchanger, thereby facilitating the removal of fouling layers.

Description

technical field [0001] The invention relates to the field of chemical equipment, in particular to a coiled tube heat exchanger. Background technique [0002] The heat exchanger is one of the important chemical equipment in the chemical plant. There are many types of heat exchangers with different characteristics, which can be selected according to the requirements of the production process. According to the heat transfer principle and the method of realizing heat exchange, heat exchangers can be divided into partition wall heat exchangers, hybrid heat exchangers and regenerative heat exchangers. Among them, the partition wall heat exchanger is the most commonly used. The characteristic of the partition wall heat exchanger is that the cold and hot fluids are separated by a solid wall, do not mix, and exchange heat through the partition wall. [0003] The submerged coil heat exchanger in the partition wall heat exchanger has a simple structure, low price, is easy to prev...
