Background technology:
The present two-stage heat exchange unit that uses, its first-class heat exchanger is a pipe heat exchanger, adopts the carbonated drink indirect heat exchange.Be to utilize steam latent heat that secondary media is heated, the synthermal saturation water that congeals into behind the steam heat-exchanging is discharged through steam trap.Heat content accounts for about 20% of steam total amount of heat in the saturation water.Adopt common mode to reclaim, cause secondary flash distillation and energy loss, set heat exchange efficient is low; Secondary heat exchanger adopts plate type heat exchanger, is water water indirect heat exchange.And secondary media must pass through the I and II heat exchanger respectively, increased the operation power consumption, and take up an area of big, maintenance difficult.
Summary of the invention:
The purpose of this utility model is to provide a kind of energy-efficient vapour melt water plate type heat exchanger unit that can improve set heat exchange efficient.
Technology contents of the present utility model is: a kind of energy-efficient vapour melt water plate type heat exchanger unit, comprise plate type heat exchanger unit and the pipeline that connects this unit, pump and valve, be characterized in that addition has the vapour melt water to mix water heater before the plate type heat exchanger unit, it is an airtight tank body that described vapour melt water mixes water heater, the tank body top is connected with steam inlet and takes over, be provided with spray header in the tank body, siphon pipe and drainpipe, the tank body bottom is connected with the condensed water entrance sleeve, spray header is positioned at the tank body center, its lower end links to each other with condensed water entrance sleeve upper end, condensed water entrance sleeve lower end links to each other with the plate type heat exchanger condensation-water drain by water circulating pump, condensed water entrance sleeve one side is provided with overflow pipe, the siphon pipe lower end is inserted in the tank body, the upper end passes with the import of plate type heat exchanger thermal source from tank body one side and links to each other, the drainpipe lower end places the tank body bottom, and stretch out from tank wall the upper end.
The utility model adopts the vapour melt water to mix water heater high-temperature steam (can reach 300 ℃) and the water smoke that spray header sprays directly are mixed into high-temperature water in vapour melt water hybrid heater, enter again and carry out water-hydrothermal exchange in the plate type heat exchanger, when having avoided having the vapour of steam trap-water indirect heat exchanger operation because the hydrophobic thermal loss that causes, improved the heat exchange efficiency of unit, energy-conservation 25～33%.Owing to adopting vapour-water, first-class heat exchanger of the present utility model in jar, directly mixes again, compact conformation, and floor space is little, and is easy for installation, and power consumption is low, and operating cost is low.
Description of drawings:
Fig. 1 is a general structure schematic diagram of the present utility model.
Fig. 2 is a fundamental diagram of the present utility model.
The specific embodiment:
As Fig. 1, the utility model is a kind of energy-efficient vapour melt water plate type heat exchanger unit.Form by pipeline, pump and valve etc. that plate type heat exchanger unit 2, vapour melt water mix water heater 3, touch-screen and programmable controller 1 and connect this unit.The vapour melt water mix water heater 3 be one have on, the airtight cylindrical tank 5 of low head, tank body 5 tops are connected with steam inlet and take over 4, be provided with spray header 9 in the tank body 5, drainpipe 10 and siphon pipe 8, tank body 5 bottoms are connected with condensed water entrance sleeve 12, offer some water spray through holes 11 on the spray header 9 tube wall faces, spray header 9 is positioned at tank body 5 centers, its lower end links to each other with condensed water entrance sleeve 12 upper ends, condensed water entrance sleeve 12 lower ends link to each other with plate type heat exchanger 2 condensation-water drains by water circulating pump 14, condensed water entrance sleeve 12 1 sides are provided with overflow pipe 13, and unnecessary water can be discharged by overflow pipe 13.Drainpipe 10 lower ends place tank body 5 bottoms, and stretch out from tank wall the upper end, and water unnecessary in jar can be discharged by this drainpipe.Siphon pipe 8 upper ends pass with plate type heat exchanger 2 thermal source imports from tank body 5 one side levels and link to each other.For keeping the high heat transfer coefficient and the security of operation of heat exchanger, device has air bleeding valve 7 on siphonal external part, and tank body 5 upsides are equipped with air bleeding valve 7 and Pressure gauge 6.Adopt electron controls technology and equipment such as Programmable Logic Controller, realized the electromechanical integration and the intellectuality of unit.
