A disk and ring type baffle plate floating head heat exchanger with temperature control function

Abstract

The invention relates to a temperature-controllable floating head heat exchanger with disc and loop type baffling plates. The temperature-controllable floating head heat exchanger comprises a casing and is characterized in that a center passage with a heat insulation layer on the inner wall is arranged in the casing, one end of the center passage extends into a head cavity, the other end of the center passage is communicated with a pipe pass fluid cavity, a center passage butterfly valve is arranged in the center passage, pipe pass fluid entering the head cavity from a pipe pass inlet flows into heat exchange pipes from a pipe pass butterfly valve in the head cavity and into the pipe pass fluid cavity along the heat exchange pipes, and at least one loop baffling plate and at least one disc baffling plate are arranged in the casing. The temperature-controllable floating head heat exchanger has the advantages that heat exchange coefficient of the heat exchanger is effectively increased, heat exchange area is decreased, manufacturing cost of equipment and flowing resistance of the casing pass fluid are reduced effectively, power cost of the heat exchanger during running is saved, and stable running of downstream equipment of the heat exchanger is effectively guaranteed.

Description

technical field [0001] The invention relates to a heat exchanger. Background technique [0002] With the gradual increase of the country's requirements for low-carbon and energy-saving, the rough production methods of the chemical industry are becoming less and less suitable for the development requirements of modern industry. Lots of improvement work. Among them, the recovery and utilization of waste heat in the production process of chemical products has become an effective way to improve energy utilization. As the main equipment for waste heat recovery, the heat exchanger is becoming more and more important in the chemical process. According to statistics, the number of heat exchangers accounts for about 40% of the chemical equipment used, and its investment cost also reaches more than 20%. [0003] The heat exchangers currently used mainly have the following disadvantages: under variable load conditions, the heat exchanger cannot maintain steady-state operation; after ...

Problems solved by technology

[0003] The heat exchangers currently used mainly have the following disadvantages: under variable load conditions, the heat exchanger cannot maintain steady-state operation; after the tube-side fluid exchanges heat with the shell-side fluid, the outlet temperature often does not reach the design temperature. Make the downstream equipment of the heat exchanger unable to maintain steady state operation
