Plate type heat exchanger

Abstract

The invention relates to a plate type heat exchanger. A plurality of heat exchange plates are uniformly distributed in parallel between a front fixed plate and a rear moveable plate; a support columnfor supporting the rear moveable plate is connected with the rear moveable plate; an upper guide rod is mounted at the upper ends of the heat exchange plates; a lower guide rod is mounted at the lowerends of the heat exchange plates; the front fixed plate, heat exchange plates and the rear moveable plate are connected in a fastened manner through clamping bolts; a hot fluid inlet tube and a coldfluid outlet tube arranged in parallel are arranged at the upper ends of the front fixed plate and the heat exchange plates; a hot fluid outlet tube and a cold fluid inlet tube arranged in parallel are arranged at the lower ends of the front fixed plate and the heat exchange plates; the hot fluid inlet tube, the cold fluid outlet tube, the hot fluid outlet tube and the cold fluid inlet tube can bemoved along corresponding connecting holes in the front fixed plate and the heat exchange plates. The number of the heat exchange plates can be adjusted by changing positions of the hot and cold fluid inlet / outlet tubes in heat exchange, furthermore heat exchange areas can be changed, and the purpose of changing heat can be achieved.

Description

technical field [0001] The invention relates to a heat exchanger, in particular to a plate heat exchanger. Background technique [0002] The plate heat exchanger is a high-efficiency heat exchanger composed of a series of metal sheets with a certain corrugated shape. A channel of a certain shape is formed between various plates. Through the plates, the hot fluid transfers part of the heat to the cold fluid. . Plate heat exchanger, as a kind of thermal power mechanical equipment with excellent heat transfer performance, is widely used in many fields with energy conversion process. The continuous expansion of its application range requires more in-depth research on it. Once most of the existing plate heat exchangers are processed and cast, it is impossible to adjust the amount of heat exchange by changing the number of heat exchange plates, while a small part of detachable plate heat exchangers can change the number of heat exchange plates. However, when they change the numb...

Problems solved by technology

[0003] The technical problem to be solved in the present invention is to solve the problem that the above-mentioned existing plate heat exchanger cannot adjust the number of heat exchange plates or needs to consume manpower and lose money to dismantle the number of heat exchange plates in the heat exchanger, and provides a method that can not be adjusted. It is necessary to suspend the operation of the system, and the number of heat exchange plates can be adjusted at any time to achieve a new type of plate heat exchanger that can adjust the amount of heat exchange
