Description
Technical field
The utility model relates to heat-transfer technology field, particularly relates to a kind of energy-conserving and environment-protective separate type heat exchanger.
Background technology
Separate type heat exchanger is high owing to having heat transfer efficiency, long-range heat transfer, site layout project advantage and using more and more widely flexibly, its maximum feature is that evaporator section and condensation segment can be separate, the operation principle of existing separate type heat exchanger is: hot fluid to be heated rising at evaporator section, through vapour conduit at condensation segment exothermic condensation, condensate liquid is back to evaporator section by gravity through fluid catheter, condensation segment lower collecting box is equipped with air bleeding valve is housed, at any time incoagulable gas separaion can be discharged, but the heat of self can distribute in the process that steam is carried in airway, thus cause steam liquefaction backflow, to the inhibition that the flowing of steam produces, greatly reduce heat exchange efficiency, very large inconvenience is brought to the use of heat exchanger, and steam is spurted in condensation segment with post type, not only certain vapours impact damage is caused to the element of condensation segment inside, shorten the service life of heat exchanger, also reduce the condensation efficiency of vapours.
Summary of the invention
According to above technical problem, the utility model provides a kind of energy-conserving and environment-protective separate type heat exchanger of anti-backflow, comprises evaporator section, snakelike heat exchange tube, vapour conduit, upper header, condensation segment, cold water outlet, lower collecting box, exhaust outlet, fluid catheter, is characterized in that: also comprise reflux tank, fluid column, return duct, flared tube, the inside of described evaporator section is provided with snakelike heat exchange tube, the upper end of described snakelike heat exchange tube is connected with one end of vapour conduit, described vapour conduit is structure of right angle tyoe, the corner position of described vapour conduit is provided with reflux tank, described reflux tank is provided with fluid column, the other end of described vapour conduit is connected with upper header by flared tube, the lower end of described upper header is provided with condensation segment, described condensation segment is provided with cold water outlet, the lower end of described condensation segment is provided with lower collecting box, described lower collecting box is provided with exhaust outlet, and described fluid catheter is structure of right angle tyoe, and one end of described fluid catheter is connected with the bottom of lower collecting box, the other end of described fluid catheter and the lower end of snakelike heat exchange tube connect and compose loop, and described return duct vertically arranges and is communicated with fluid catheter by reflux tank.
The beneficial effects of the utility model are: the utility model improves on original separate type heat exchanger, namely reflux tank, fluid column, return duct is added, condensate water in vertical vapour conduit can be collected by reflux tank, flow into fluid catheter from return duct again and circulate, not only energy-conserving and environment-protective, also substantially reduce the inhibition because steam liquefaction backflow produces the flowing of steam, thus increase heat exchange efficiency, fluid column can carry out liquid level display to the liquid collected in reflux tank, facilitates use; Also add flared tube, flared tube can not only prevent steam condensation in horizontal vapour conduit from flowing backwards, the structure of enlarging can also reduce gas flow rate, increase heat exchange area, thus reduce vapours the high temperature impact of the element of condensation segment inside is damaged, extend the service life of heat exchanger, increase condensation efficiency.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Detailed description of the invention
According to Fig. 1, the utility model is further described:
As Fig. 1, evaporator section-1, snakelike heat exchange tube-2, vapour conduit-3, upper header-4, condensation segment-5, cold water outlet-6, lower collecting box-7, exhaust outlet-8, fluid catheter-9, reflux tank-10, fluid column-11, return duct-12, flared tube-13.
Embodiment 1
The utility model comprises evaporator section 1, snakelike heat exchange tube 2, vapour conduit 3, upper header 4, condensation segment 5, cold water outlet 6, lower collecting box 7, exhaust outlet 8, fluid catheter 9, reflux tank 10, fluid column 11, return duct 12, flared tube 13, first cold water outlet 6 is arranged on condensation segment 5 during installation, exhaust outlet 8 is arranged on lower collecting box 7, then by upper header 4, condensation segment 5, lower collecting box 7 is connected and installed from top to bottom successively, then fluid column 11 is arranged on reflux tank 10, reflux tank 10 is arranged on the corner position of vapour conduit 3, again snakelike heat exchange tube 2 is fixedly mounted on the inside of evaporator section 1, then the upper end of one end of vapour conduit 3 with snakelike heat exchange tube 2 is connected, the other end is connected with upper header 4 by flared tube 13, the bottom of one end of fluid catheter 9 with lower collecting box 7 is connected, the lower end of the other end and snakelike heat exchange tube 2 connects and composes loop, reflux tank 10 is communicated with fluid catheter 9 by the return duct 12 arranged finally by numerical value.
Embodiment 2
During use, hot fluid transmits after evaporator section 1 is heated vaporization in vapour conduit 3, rise along vapour conduit 3 after reflux tank 10, upper header 4 is entered again through flared tube 13, flared tube 13 can not only prevent steam condensation in horizontal vapour conduit 3 from flowing backwards, the structure of enlarging can also reduce gas flow rate, reduce vapours to damage the high temperature impact of the element of condensation segment 5 inside, steam in upper header 4 enters condensation segment 5 and carries out exothermic condensation due to gas pressure, condensate liquid moves downward by gravity, the gas separaion that can not be condensed by air bleeding valve when lower collecting box 7 is discharged, circulate in the lower end that condensate liquid is back to coiled pipe by fluid catheter 9, reflux tank 10 is collected the condensate water in vertical vapour conduit 3, liquid level in fluid column 11 pairs of reflux tanks 10 shows, liquid in reflux tank 10 flows into fluid catheter 9 from return duct 12.
The above is only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvement, these improvement also should be considered as protection domain of the present utility model.
