Abstract

The utility model relates to a heat exchanger having conduits being arranged in parallel spaced relation. The heat-exchange equipment whose appearance is made of a smooth tube is replaced by a needle ribbed tube. The utility model has the advantages of large heat exchange area of specific volume equipment, high heat utilization coefficient, strong heat exchange ability and easy fabrication, and is suitable for heat exchange equipment of various industries such as chemical industries, instrument industries, medicine industries, etc.

Description

Pin ribbed pipe Lie Wenshi heat exchanger

Adopt the steam heated reaction mass maybe need add heat-transfer pipe in the chemical industry, food, medical industry tradition heat transmission equipment Lie Wenshi heat exchanger of thermal material, be to adopt the smooth tubing manufacturing of external surface area, the heat exchange area that heat exchange amount size and heat exchange tubing provide in heat exchanging process, the hot working fluid fluid velocity, turbulence intensity is relevant in heat exchanger.The heat exchange area of traditional levin's tube formula heat exchanger increases, and can only rely on increase tubulation quantity just can solve.Heat-exchange capacity increases, and can only rely on to set up the deflection plate mode and reach, and the heat-exchange capacity and the effect that improve unit volume equipment often can't realize because of the difficulty of Material Strength and processing conditions harshness.

This is suitable for novel purpose and provides a kind of novel levin's tube formula heat exchanger.The pin ribbed pipe that tubing in this utensil adopts the technology of China Patent No.: ZL95242745.8 to make replaces the traditional piping material of smooth outer surface, because it is big that the pin ribbed pipe has an external surface area, when many pin ribbed pipes are arranged side by side, the pin intercostal is staggered to form the passage that Cong Heng intersects, and the pin rib takies and forms in the shell chamber at a high speed after can making behind the shell cavity space steam enter the shell chamber, disorderly strong flowing is because of heat transfer area and turbulent flow increase, so can improve biography (changing) thermal effect.

This is suitable for novel each pipe two ends that will have the pin rib that are achieved in that and is individually fixed on the upper and lower orifice plate, and upper and lower orifice plate is fixed on the housing, and upper and lower end socket is individually fixed on the upper and lower orifice plate, promptly obtains pin ribbed pipe Lie Wenshi heat exchanger.When with a plurality of the pin ribbed pipe being arranged, upper and lower orifice plate after the mode that the Duan Jie of housing connects another orifice plate by up-hole plate connects, when the most end is not fixed upper and lower end socket respectively on upper and lower orifice plate, just can form multistage pin ribbed pipe Lie Wenshi heat exchanger.The utensil that makes according to such scheme, owing to adopted the pin ribbed pipe to substitute the smooth outer surface pipe, utilize the pin rib to increase and pass the long-pending while of (changing) hot side, utilized the Cong Heng cross aisle that is staggered to form of pin intercostal, hot working fluid turbulence intensity and flow velocity have been improved, thereby can improve heat-transfer effect and heat exchange amount effectively, reach energy-conservation purpose.

This is suitable for novel concrete structure and will further provides by following examples and accompanying drawing.

Fig. 1 is this vertical part sectioned view that is suitable for the pin ribbed pipe Lie Wenshi heat exchanger of novel proposition.

Fig. 2 is section (the A-A ') figure of this utensil.

As shown in the figure, this utensil is by pin ribbed pipe 1, housing 2, and up-hole plate 5, orifice plate 3, upper cover 6, low head 4 is formed.High-temperature vapour enters in the heat exchanger by table body 2 upper inlets 7 and passes through 1 heat exchange of pin ribbed pipe with pin ribbed pipe 1 interior material, and condensed water or low-temperature steam are discharged from housing 2 upper outlets 8.Low-temperature material after material inlet 9 enters heat exchanger on the low head 4, in pin ribbed pipe 1 hole by the time and pin ribbed pipe 1 outside elevated temperature heat working medium carry out heat exchange by pin ribbed pipe 1 after the material outlet 10 of upper cover 6 is discharged, thereby the heat exchange of the existing material of head.

Claims

1, a kind of pin ribbed pipe Lie Wenshi heat exchanger, this utensil is by upper and lower end socket, upper and lower orifice plate, many pin ribbed pipes, housing is formed, and it is characterized in that the pin ribbed pipe is fixed in up-hole plate (5), orifice plate (3), and up-hole plate (5), orifice plate (3) are separately fixed on the housing (2), upper cover (4) is fixed on the up-hole plate (5), and low head (4) is fixed on the orifice plate (3).

2, two terminations of pin ribbed pipe (1) are connected to a fixed with up-hole plate (5), orifice plate (3) after can be adopted and be removed the pin rib or weld other tubing again.

3, this utensil can connect a plurality of head units of not sealing up before not installing end socket additional, presses up-hole plate 5 ends and another orifice plate (3) end and connect, connects fixed seal head composition multi-stage heat exchanger respectively at end not again.
