Description
Technical field
The present invention relates to indirect heat exchange vaporization type condensing systems, more particularly, between the general vapour of concentration evaporator system end effect
Connect heat exchange vaporization type condensing system.
Background technology
At present to the condensation of the general vapour of concentration evaporator system end effect, generally by direct water-cooling device or indirectly using water at low temperature
Condenser condenses to cool down.The type of cooling of direct water-cooling device is that water directly contact with general vapour steam is condensed, make condensed water and
Cooling water mixes, and cooling water can be contaminated；The type of cooling of indirect condenser is that water at low temperature is indirect by condenser
Heat exchange condenses steam, and condensed water is not contacted with cooling water, and cooling water is not contaminated.
Either still general vapour is condensed using indirect condenser using direct water-cooling device, is the liter by cold water
Temperate zone walks heat and general vapour is condensed, and the high-temperature water after heating, which will also cool to recycle after becoming cold water by cooling tower, to be made
With.But due to general vapour condensation release be water latent heat of phase change, cold water absorb heat be water heating sensible heat, this just makes
The sensible heat for obtaining Unit Weight water is much smaller compared with the latent heat of water, so the demand of cooling water is very big, causes cycle pumped water flow rate
And conveying needed for power it is larger, also need to configure larger cooling tower, hot-tub, water cooling pond, pumping plant etc. thus so that operation at
This and cost of investment are higher.
Invention content
Present invention aims at defects existing for the above-mentioned prior art, it is proposed that a kind of concentration evaporator system end
The indirect heat exchange vaporization type condensing system for imitating general vapour reduces operation and cost of investment to realize, increases the purpose of benefit.
To achieve the above object, the present invention takes following technical proposals：
The indirect heat exchange vaporization type condensing system of the general vapour of concentration evaporator system end effect of the present invention, including roof offer and draw
The air-introduced machine at the air-vent is arranged in the shell in air port；Spray tube, heat exchange are arranged at intervals in the shell from top to bottom
Device and collecting chamber；The air intake of the heat exchanger is connected with the general vapour pipe outlet of end effect, the gas outlet of heat exchanger and vacuum pump
Air inlet is connected, and the condensed water water outlet of heat exchanger is connected with condensate water pot water inlet, the condensate water pot water outlet with
Condensate pump water inlet is connected；Positioned at housing bottom the collecting chamber discharge outlet by water circulating pump and the spray tube into
The mouth of a river is connected.
The heat exchanger is shell and tube or plank frame.
In the shell water collection device is provided between the air-introduced machine and the spray tube.
The invention has the advantages that it is compact-sized, reasonable, by traditional general vapour condensation of evaporator system end effect, circulating water
Two processes are combined into one, and two kinds of general vapour condensation, circulating water courses of work, equipment investment cost are completed in an equipment
It is low；Cooling water evaporation outside due to heat exchange element is condensed into for general vapour in being absorbed when water vapour and latent heat, with heat exchange element
The latent heat released when water is suitable, so cooling water inflow is suitable with general vapour amount so that the demand of cooling water substantially reduces, and adopts simultaneously
It can be made to keep certain negative pressure inside evaporative condenser with air-introduced machine, reduce evaporating temperature, further reduce water consumption
Amount.Simultaneously the present invention indirect heat exchange vaporization type condensing system due to circulating cooling water it is few, power consumption is low when pretending industry, easy to control
Easy to operate, maintenance cost is low；The general vapour condensed water of vapo(u)rization system end effect can be recycled, there is huge energysaving effectiveness, society's effect
Benefit and application prospect.
Description of the drawings
Fig. 1 is the structural schematic diagram of the present invention.
Specific implementation mode
It elaborates below in conjunction with the accompanying drawings to the embodiment of the present invention, the present embodiment before being with technical solution of the present invention
It puts and is implemented, give detailed embodiment and specific operating process, but protection scope of the present invention is not limited to down
State embodiment.
As shown in Figure 1, the indirect heat exchange vaporization type condensing system of the general vapour of concentration evaporator system end effect of the present invention, packet
Include the shell 2 that roof offers air-vent 1, the air-introduced machine 3 being arranged at air-vent 1；It is arranged at intervals with from top to bottom in shell 2
Water collection device 4, spray tube 5, tubular heat exchanger 6 and collecting chamber 7 are provided with cooling water replenishment mouth 8 on 2 side wall of shell；Shell and tube
The air intake of heat exchanger 6 is connected with the general outlet of steam pipe road 9 of end effect, gas outlet and 10 air inlet of vacuum pump of tubular heat exchanger 6
Mouth is connected, and the condensed water water outlet of tubular heat exchanger 6 is connected by pipeline with 11 water inlet of condensate water pot, condensate water pot
11 water outlets are connected with 12 water inlet of condensate pump；Positioned at 1 bottom of shell 7 discharge outlet of collecting chamber by water circulating pump 13 with
5 water inlet of spray tube is connected.
The heat released when being condensed into the general vapour in tubular heat exchanger 6 makes the shower water outside tubular heat exchanger 6 steam
Hair, self-induced-air mouth 1 drains into air under the effect of air-introduced machine 3.
Sensible heat when absorbing a large amount of latent heat and coolant-temperature gage raising when the present invention is by spray water evaporation realizes shell and tube
General vapour condensation in heat exchanger 6, at the same the heat taken away of the cold air stream heating that enters of 6 lower part of tubular heat exchanger make it is unevaporated
Shower water flows into lower part collecting chamber 7, is sent in the spray tube 5 above tubular heat exchanger 6 through water circulating pump 13, through nozzle
After spray, forms water film along 6 surface of tubular heat exchanger and flow down, realize the recycling of shower water.
Water collection device 4 is provided with above spray tube 5, it is therefore an objective to the water droplet that spray tube 5 sprays be avoided to take shell out of by humid air
Body 2；The water droplet that water collection device 4 is collected flows back into after collecting in the collecting chamber 7 of bottom.
Air stream can be made constantly to enter in shell 2 from bottom using air-introduced machine 3, while 2 inside of shell being made to keep certain
Negative pressure, to reduce evaporating temperature, to further decrease water consumption.
Collecting chamber 7 is equipped with water-level control apparatus, and water level can carry out moisturizing in time when reducing.
