Embodiment Construction

[0025] The invention patent will be further described below in conjunction with the accompanying drawings.

[0026] Such as figure 1 As shown, the counter-flow plate heat exchanger with independent deflectors provided by the patent of the present invention is mainly composed of a certain number of heat transfer plates, sealing gaskets 14, mounted on the heat transfer plates A7 and the rear end plate 9 Independent deflector 10 and independent deflector 11 mounted on heat transfer plate B8, fixed compression plate 1, movable compression plate 2, fastening bolts and nuts 13, upper and lower guide rods 4 and 5, guide rod bracket 3, etc. components. The heat transfer plate A7 and the heat transfer plate B8 are two adjacent heat transfer plates, forming a flow channel, which is the core component of the plate heat exchanger. The sealing gasket 14 is pasted on the heat transfer plate, and the heat transfer plate pasted with the sealing gasket 14 is placed on the fixed compression p...

Abstract

The invention discloses a counter flow type plate heat exchanger comprising independent flow guide plates in a petrochemical device. The counter flow type plate heat exchanger comprising the independent flow guide plates comprises heat transfer plates, sealing gaskets, a fixed pressing plate, a movable pressing plate, pressing bolts and nuts, and upper and lower guide rods. The counter flow type plate heat exchanger comprising the independent guide plates is characterized in that flow guiding areas of the heat transfer plates are flat plates, the flow guiding areas of the heat transfer platesare fixedly provided with the independent flow guide plates, the thickness of the independent flow guide plates are equal to that of the heat transfer plates, and the shape of the independent flow guide plates is consistent with that of the flow guiding areas of the heat transfer plates. The counter flow plate heat exchanger with the independent flow guide plates has the advantages that the flow guide effect of the independent flow guide plates at an inlet is good, the fluid is uniformly distributed, the heat exchange dead zone of the plate heat exchanger can be effectively reduced, and the heat exchange efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of plate heat exchangers in petrochemical plants, and in particular relates to a counter-flow plate heat exchanger with independent deflectors. Background technique [0002] As a compact and efficient heat exchange equipment, the plate heat exchanger has the advantages of compact and light structure, good heat transfer effect, large logarithmic average temperature difference, strong interchangeability, flexible disassembly, convenient maintenance and cleaning, and low operating costs. , It is widely used in oil refining units and has played a good economic benefit. The detachable plate heat exchanger is assembled from a series of thin metal sheets parallel to each other with corrugated surfaces, rubber pads, compression plates, compression bolts, brackets and other components. [0003] Metal corrugated plates are the most important heat exchange elements of plate heat exchangers. It is necessary to ensure t...
