Abstract
The utility model provides a horizontal type shell-and-tube condenser. A technical measure that the thickness of a condensing liquid film outside a condensing heat exchanging pipe in a horizontal type heat exchanging pipe bundle can be reduced and the thermal resistance of the condensing liquid film outside the condensing heat exchanging pipe can be lowered does not exist at present. The horizontal type shell-and-tube condenser comprises a shell body (1) which is provided with an air inlet (2) and a liquid outlet (3). Two sides of the shell body (1) are connected with tube plates (4). An inside-shell space which is formed by the shell body and the tube plates in a surrounding mode is provided with a group of heat exchanging pipes (5). A rubber sleeve (6) is arranged outside each heat exchanging pipe. The rubber sleeves are connected with a push-pull head (8) through a connecting rod (7). The push-pull head is movably connected at one end of a lead screw (9). The other end of the lead screw is connected with a driven gear (10) through a thread. The driven gear is meshed with a driving gear (11) which is connected with a driving motor (12) which is connected with a timing controller (13). The horizontal type shell-and-tube condenser is used in the fields of petroleum, chemical industry, metallurgy, pharmacy, air conditioning, refrigeration, heat supply and the like.
Description
Technical field
The utility model relates to a kind of chemical machinery, is 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 have obtained a large amount of fruitful achievements by changing the tube outer surface architectural characteristic.Yet these work do not solve in the 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 the design closed shell and tube condenser, people can only rely on the quantity that increases heat exchanger tube to compensate the tube bank effect to the adverse effect of 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, 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 the drainage plate outside heat exchanger tube under gravity and capillary effect, and flow in the drainage device, liquid in the last drainage device is directed to the 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, had 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 to flow on the drainage plate outside heat exchanger tube under gravity and capillary effect, and flow in the drainage device, liquid in the last drainage device is directed to the heat exchanger tube two ends, this method only has when the heat exchanger tube liquid film is increased to certain thickness and could naturally flow 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 this closed shell and tube condenser with drainage device can not solve.
Summary of the invention
The purpose of this utility model is that the problem for above-mentioned existence provides a kind of closed shell and tube condenser, can in time remove the liquid film on the exchanger tube wall, improves its heat exchange efficiency.
Above-mentioned purpose is achieved through the following technical solutions:
Closed shell and tube condenser, comprise: housing, have air inlet and liquid outlet on the described housing, described housing both sides connect tube sheet, one group of heat exchanger tube is equipped with in the space in the shell that described housing and described tube sheet surround, a rubber sleeve is installed in each described heat exchanger tube outside, described rubber sleeve connects the push-and-pull head by connecting rod, described push-and-pull head is movably connected in an 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, 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 utility model drives the driving gear rotation by timing controller control drive motors, driving gear drives driven gear, 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.
2. the utility model has improved the overall heat exchange efficient of heat-exchanging tube bundle, reduces equipment volume, reduces the condenser heat-exchange pipes material consumption.Therefore, the utility model can be widely used in the fields such as oil, chemical industry, metallurgy, pharmacy, air-conditioning, refrigeration and heat supply.
