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 fields such as oil, chemical industry, metallurgy, pharmacy, air-conditioning, refrigeration and heat supply; The height of its heat exchange efficiency directly affects commercial production cost and efficiency of energy utilization, so it is important research always and improves object.Since the seventies in last century, to how improving condensing heat exchanger heat exchange property problem, people have obtained a large amount of fruitful achievements through changing the tube outer surface architectural characteristic.Yet these work do not solve in the closed shell and tube condenser following of comb condensate liquid, cause that down row's heat exchanger tube liquid film thickens and causes restraining the whole heat exchange property decline problem of (be called and restrain effect).When the design closed shell and tube condenser, people can only rely on the quantity that increases 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 are seeking a kind of technical measures that can reduce condensing heat-exchange out-tubular condensing thickness of liquid film in the horizontal heat-exchanging tube bundle, reduction out-tubular condensing liquid film thermal resistance, improve the whole condensing heat-exchange efficient of tube bank always.
Patent application CN200910072510.9 discloses a kind of closed shell and tube condenser with drainage device; Drainage plate and drainage device are installed in bottom through at heat exchanger tube; Drainage plate closely contacts with heat exchanger tube, and condensate liquid flows on the drainage plate outside heat exchanger tube under gravity and capillary effect, and flows in the drainage device; Liquid in the last drainage device is directed to the heat exchanger tube two ends; Avoid the condensing droplet of last layer heat exchanger tube to fall down on one deck heat exchanger tube, thereby avoided the increase of time one deck heat exchanger tube liquid film, had the effect of eliminating tube bank effect, the heat exchange of enhanced heat exchange out-tubular condensing.But this application mainly relies on condensate liquid under gravity and capillary effect, outside heat exchanger tube, to flow on the drainage plate; And flow in the drainage device; Liquid in the last drainage device is directed to the heat exchanger tube two ends, and this method has only when the heat exchanger tube liquid film is increased to certain thickness and could flow to naturally on the 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 the closed shell and tube condenser of this band drainage device can not solve.
Summary of the invention
The objective of the invention is provides a kind of closed shell and tube condenser to the problem of above-mentioned existence, can in time remove the liquid film on the exchanger tube wall, improves its heat exchange efficiency.
Above-mentioned purpose realizes through following technical scheme:
Closed shell and tube condenser comprises: housing has air inlet and liquid outlet on the described housing; Described housing both sides connect tube sheet, and one group of heat exchanger tube is equipped with in the space in the shell that described housing and described tube sheet surround, and a rubber sleeve is installed in each described heat exchanger tube outside; Described rubber sleeve connects the push-and-pull head through connecting rod; Described push-and-pull head is movably connected in an end of leading screw, and the other end of described leading screw is through the driven gear that is threaded, and described driven gear and driving gear mesh; Described driving gear connects drive motors, and described drive motors connects timing controller.
Below the described closed shell and tube condenser, described rubber sleeve liquid-collecting bottle is housed.
Beneficial effect:
1. the present invention drives the driving gear rotation through timing controller control drive motors; Driving gear drives driven gear; Driven gear drives leading screw and moves back and forth, thereby drive rubber sleeve the liquid film on the heat exchanger tube is scraped off, and 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 whole heat exchange efficiency of heat-exchanging tube bundle, reduces equipment volume, reduces the consumption of condenser heat exchange tube material.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 accompanying drawing and the specific embodiment, further illustrate the present invention.
Embodiment 1:
Shown in accompanying drawing 1: closed shell and tube condenser of the present invention comprises: housing 1 has air inlet 2 and liquid outlet 3 on the described housing; Described housing both sides connect tube sheet 4, and one group of heat exchanger tube 5 is equipped with in the space in the shell that described housing and described tube sheet surround, and a rubber sleeve 6 is installed in each described heat exchanger tube outside; Described rubber sleeve connects push-and-pulls 8 through connecting rod 7; Described push-and-pull head is movably connected in an end of leading screw 9, and the other end of described leading screw is through the driven gear 10 that is threaded, and described driven gear and driving gear 11 mesh; Described driving gear connects drive motors 12, and described drive motors connects timing controller 13.
Embodiment 2:
Below the described closed shell and tube condenser, described rubber sleeve liquid-collecting bottle 14 is housed.Liquid-collecting bottle is used for the liquid that scrapes off from heat exchanger tube is collected, and avoids dropping on down on one deck heat exchanger tube.
The course of work:
In condenser working after a period of time; Drive driving gear by timing controller control drive motors and rotate, driving gear drives driven gear, and driven gear drives leading screw and moves back and forth; Thereby driving rubber sleeve scrapes off the liquid film on the heat exchanger tube; 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 that scrapes off directly gets into liquid-collecting bottle.
