Abstract
The invention provides a horizontal shell-and-tube condenser, which is used for solving the problem that a technical measure which can reduce the thickness of a condensate liquid film outside one condensation heat exchange tube in a horizontal tube bundle and reduce the heat resistance of the condensate liquid film outside the tube is in lack nowadays. The horizontal shell-and-tube condenser comprises a shell body (1); the shell body is provided with an air inlet (2) and a liquid outlet (3); the two sides of the shell body are connected with tube plates (4); a group of heat exchange tubes (5) are mounted in the space in a shell which is formed by the shell body and the tube plates in an encircling manner; a rubber sleeve (6) is mounted outside each heat exchange tube; the rubber sleeves are connected with a push-and-pull head (8) through a connecting rod (7); the push-and-pull head is movably connected to one end of the screw rod (9); the other end of the screw rod is connected with a driven gear (10) through threads; the driven gear is engaged with a driving gear (11); the driving gear is connected with a driving motor (12); and the driving motor is connected with a timing controller (13). The horizontal shell-and-tube condenser is applied to the fields of petroleum, chemical industry, metallurgy, pharmacy, air conditioning, refrigeration, heating and the like.
Description
Technical field
The present invention relates to a kind of chemical machinery, be specifically related to a kind of closed shell and tube condenser.
Background technology
Closed shell and tube condenser is widely used in the fields such as oil, chemical industry, metallurgy, pharmacy, air-conditioning, refrigeration and heat supply, the height of its heat exchange efficiency directly affects industrial production cost and efficiency of energy utilization, so it is important research always and improves object.Since the seventies in last century, for how improving condensing heat exchanger heat exchange property problem, people, by changing tube outer surface architectural characteristic, have obtained a large amount of fruitful achievements.Yet these work do not solve in closed shell and tube condenser lower of comb condensate liquid, cause that lower row's heat exchanger tube liquid film thickens and causes restraining the overall heat exchange hydraulic performance decline problem of (be called and restrain effect).When design closed shell and tube condenser, people can only rely on the quantity of increase heat exchanger tube to compensate the adverse effect of tube bank effect to condensing heat-exchange, thereby cause the increase of heat transmission equipment volume and the raising of manufacturing cost at present.Therefore, people seek always a kind of can reduce horizontal heat-exchanging tube bundle in condensing heat-exchange out-tubular condensing thickness of liquid film, reduce out-tubular condensing liquid film thermal resistance, improve the technical measures of the whole condensing heat-exchange efficiency of tube bank.
Patent application CN200910072510.9 discloses a kind of closed shell and tube condenser with drainage device, by the bottom at heat exchanger tube, drainage plate and drainage device are installed, drainage plate and heat exchanger tube close contact, condensate liquid flows on drainage plate under gravity and capillary effect from heat exchanger tube, and flow in drainage device, liquid in last drainage device is directed to heat exchanger tube two ends, avoided the condensing droplet of last layer heat exchanger tube to fall on lower one deck heat exchanger tube, thereby avoided the increase of time one deck heat exchanger tube liquid film, there is the tube bank of elimination effect, the effect of enhanced heat exchange out-tubular condensing heat exchange.But this application mainly relies on condensate liquid from heat exchanger tube, to flow on drainage plate under gravity and capillary effect, and flow in drainage device, liquid in last drainage device is directed to heat exchanger tube two ends, this method only has when heat exchanger tube liquid film is increased to certain thickness and could naturally flow on drainage plate, when the thickness of liquid film of heat exchanger tube does not reach the critical point of drainage, heat exchange efficiency is low, and this closed shell and tube condenser with drainage device can not solve.
Summary of the invention
The object of the invention is provides a kind of closed shell and tube condenser for the problem of above-mentioned existence, can remove in time the liquid film in exchanger tube wall, improves its heat exchange efficiency.
Above-mentioned object is achieved through the following technical solutions:
Closed shell and tube condenser, comprise: housing, on described housing, have air inlet and liquid outlet, described housing both sides connect tube sheet, in the shell that described housing and described tube sheet surround, one group of heat exchanger tube is equipped with in space, a rubber sleeve is installed in heat exchanger tube outside described in each, described rubber sleeve connects push-and-pull head by connecting rod, described push-and-pull head is movably connected in one end of leading screw, the other end of described leading screw is threaded connection driven gear, described driven gear and driving gear engagement, described driving gear connects drive motors, described drive motors connects timing controller.
Described closed shell and tube condenser, is equipped with liquid-collecting bottle below described rubber sleeve.
Beneficial effect:
1. the present invention controls drive motors by timing controller and drives driving gear to rotate, driving gear drives driven gear, driven gear drives leading screw to move back and forth, thereby drive rubber sleeve that the liquid film on heat exchanger tube is scraped off, can reduce the thickness of heat exchanger tube condensed exterior liquid film, reduce out-tubular condensing liquid film thermal resistance, improve the heat exchange efficiency of heat exchanger tube.
2. the present invention has improved the overall heat exchange efficiency of heat-exchanging tube bundle, reduces equipment volume, reduces condenser heat-exchange pipes material consumption.Therefore, the present invention can be widely used in the fields such as oil, chemical industry, metallurgy, pharmacy, air-conditioning, refrigeration and heat supply.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the present invention.
Embodiment 1:
As shown in Figure 1: closed shell and tube condenser of the present invention, comprise: housing 1, on described housing, have air inlet 2 and liquid outlet 3, described housing both sides connect tube sheet 4, in the shell that described housing and described tube sheet surround, one group of heat exchanger tube 5 is equipped with in space, a rubber sleeve 6 is installed in heat exchanger tube outside described in each, described rubber sleeve connects push-and-pulls 8 by connecting rod 7, described push-and-pull head is movably connected in one end of leading screw 9, the other end of described leading screw is threaded connection driven gear 10, described driven gear and driving gear 11 engagements, described driving gear connects drive motors 12, described drive motors connects timing controller 13.
Embodiment 2:
Described closed shell and tube condenser, is equipped with liquid-collecting bottle 14 below described rubber sleeve.Liquid-collecting bottle, for by the liquid collection scraping off from heat exchanger tube, is avoided dropping on lower one deck heat exchanger tube.
The course of work:
In condenser working after a period of time, by timing controller, controlling drive motors drives driving gear to rotate, driving gear drives driven gear, driven gear drives leading screw to move back and forth, thereby drive rubber sleeve that the liquid film on heat exchanger tube is scraped off, can reduce the thickness of heat exchanger tube condensed exterior liquid film, reduce out-tubular condensing liquid film thermal resistance, improve the heat exchange efficiency of heat exchanger tube.The liquid scraping off directly enters liquid-collecting bottle.
