Abstract
The invention provides a spiral shell-and-tube heat exchanger. The spiral shell-and-tube heat exchanger comprises a plastic pipe, reducing joints, a stainless steel bellows and a cylindrical object, and is characterized in that the stainless steel bellows is made to be spiral and mounted in the plastic pipe, the cylindrical object is mounted in the spiral axis gap of the stainless steel bellows, each of the reducing joints is mounted in one of the openings at the two ends of the plastic pipe, the openings at the two ends of the stainless steel bellows are exposed outside the reducing joints, the plastic pipe and the reducing joints, as well as the openings of the reducing joints and the outer wall of the stainless steel bellows, are sealed through hot melting, injection molding, plastic welding or glue; a first connector is mounted near to the opening at one end of the plastic pipe; a second connector is mounted near to the opening at the other end of the plastic pipe; the opening at one end of the stainless steel bellows is a third connector; and the opening at the other end of the stainless steel bellows is a fourth connector. The spiral shell-and-tube heat exchanger is short in shell pass and long in tube pass; the large-caliber stainless steel bellows is adopted for flowing of waste hot water, so that the probability of blockage is low; and the spiral shell-and-tube heat exchanger can be extensively applied to waste heat recovery of waste hot water.
Description
technical field [0001] The invention relates to the field of heat exchange, in particular to a spiral shell-and-tube heat exchanger. Background technique [0002] In daily life and industrial production, the waste hot water produced contains a large amount of heat energy and has not been recycled. The main reason is that the heat recovery efficiency of the existing heat exchanger is low, and the heat exchanger is easy to be blocked. Contents of the invention [0003] In view of the above problems, the object of the present invention is to provide a spiral shell-and-tube heat exchanger. [0004] To achieve the above object, the present invention applies the following technical solutions: [0005] A spiral shell-and-tube heat exchanger according to the present invention includes plastic pipes, different-diameter joints, a stainless steel corrugated pipe and a cylindrical object, and is characterized in that: a stainless steel corrugated pipe is made into a spiral shape and ...
