Description
Technical field
The utility model belongs to heat exchange contact(-type) heater component technology field, particularly a kind of be used for the hybrid heat exchange of vapour-water revolve the film device.
Background technology
Commercial production with steam course in; When steam condenses into after water discharges heat; Can produce a certain amount of secondary flash-off steam because pressure reduces in the condensed water removal process, the secondary flash-off steam has certain heat, during prior art is used usually with indirect steam emptying; Both wasted energy, possibly cause the pollution of environment again.
At present; The form of being interrupted heat exchange is adopted in the heating of water for industrial use usually; Be that heat medium steam does not contact with the water of heated medium mutually, will inevitably bring the sensible heat after terminal temperature difference and steam condense effectively not utilize like this, and because condensing capacity is less; Efflux trench, waste when causing heat and medium.In the mixing heat-exchange field, directly feed steam in the water sometimes, noise is bigger, also has bubbling phenomenon or cavitation phenomenons and takes place.
Summary of the invention
Shortcomings and deficiencies to existing direct contact heat exchanger; What the utility model provided a kind of recovery that is used for industrial secondary flash-off steam or other water for industrial use of factory and the life heating with water revolves the film device, and this revolves, and the film device comprises rotation membrane pipe, communicating pipe, revolves the putamina body, rotation membrane pipe upper spacer, rotation membrane pipe lower clapboard and water inlet pipe, and it is columnar structured revolving the putamina body; Rotation membrane pipe upper spacer, rotation membrane pipe lower clapboard are separately fixed at upper end, the lower end of revolving the putamina body; And form the water inlet chamber with revolving the putamina body, and revolving putamina body one side and be connected with water inlet pipe, water inlet pipe is connected with outside water intaking valve; Rotation membrane pipe and communicating pipe and revolve that putamina body axis direction laterally arranges, two ends are separately fixed at the rotation membrane pipe upper spacer, on the rotation membrane pipe lower clapboard; And stretch out outside the dividing plate, rotation membrane pipe is with the regular polygon arranged in form, the rotation membrane pipe both ends open; The rotation membrane pipe inwall offers and revolves fenestra, interts communicating pipe to be arranged between the rotation membrane pipe and the periphery.
The said fenestra that revolves is offered along rotation membrane pipe inwall tangential direction, and shape distributes in the shape of a spiral, revolves fenestra and tilts to the direction of rotation membrane pipe lower clapboard.
Said rotation membrane pipe is the stainless steel tube of inner surface polishing, and the lower end delivery port is horn-like.
Be provided with impingement baffle between said water inlet pipe inlet and the rotation membrane pipe, the impingement baffle upper and lower sides is fixed between rotation membrane pipe upper spacer, the rotation membrane pipe lower clapboard, left and right sides and revolve between the putamina body inwall and leave the gap.
When this revolved the film device and is applied to the contact(-type) heater assembly operating, heated medium water got into from water inlet pipe and revolves in the rotation membrane pipe the putamina body, is rotated down along the rotation membrane pipe inwall; And when going out rotation membrane pipe, forming very thin " water skirt ", heating steam gets into rotation membrane pipe from revolving film device bottom, before steam runs into rotation membrane pipe; At first with rotation membrane pipe in " water skirt " contact; Both carry out sufficient heat exchange, and the contained most of heated medium water of heat sponges in the steam at this moment, and " water skirt " is to be formed by the heated medium water of directly importing from water intaking valve in addition; Self-temperature is lower, so can make the whole condensing and recycling of water vapour in the heat medium steam.The minute quantity moisture that contains through the incondensable gas behind the rotation membrane pipe assembly during to air bleeding valve, also can condense into globule drippage through vapour liquid separator the row of heater assembly, and system's heat exchange efficiency improves greatly.
The beneficial effect of the utility model is: this revolves the film device through increasing the heat exchange area of heat medium and heated medium; The heat of steam in vapour-water direct contact heat exchanger is effectively utilized; And make heating steam be condensed into water and heated medium water is lumped together; Realize the recovery of medium, practiced thrift freshwater resources, the commercial Application benefit very significantly.
Description of drawings
Fig. 1 be the utility model embodiment revolve film device structural representation;
Fig. 2 is the A-A cutaway view of Fig. 1;
Among the figure: 1 rotation membrane pipe, 2 communicating pipes, 3 impingement baffles, 4 revolve the putamina body, 5 rotation membrane pipe upper spacers, 6 rotation membrane pipe lower clapboards, 7 water inlet pipes.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Present embodiment revolve the film device, comprise rotation membrane pipe 1, communicating pipe 2, revolve putamina body 4, rotation membrane pipe upper spacer 5, rotation membrane pipe lower clapboard 6 and water inlet pipe 7, revolve putamina body 4 for columnar structured; Rotation membrane pipe upper spacer 5, rotation membrane pipe lower clapboard 6 are separately fixed at upper end, the lower end of revolving putamina body 4, and form the water inlet chamber with revolving putamina body 4, revolve putamina body 4 one sides and are connected with water inlet pipe 7; Water inlet pipe 7 is connected with outside water intaking valve; Rotation membrane pipe 1 and communicating pipe 2 with revolve that putamina body 4 axis directions laterally arrange, two ends are separately fixed at rotation membrane pipe upper spacer 5, on the rotation membrane pipe lower clapboard 6, and stretch out outside the dividing plate, rotation membrane pipe 1 is with the equilateral triangle arranged in form; Promptly per hour the steam thermal discharge is definite by the heat exchange amount that revolves the film device for the quantity of rotation membrane pipe 1; Rotation membrane pipe 1 both ends open, rotation membrane pipe 1 inwall offers and revolves fenestra, interts communicating pipe 2 to be arranged between the rotation membrane pipe 1 and the periphery; The water that few part is discharged by rotation membrane pipe 1 top passes back into communicating pipe 2 again, is reclaimed by communicating pipes 2 lower end discharge again.
