Description
Technical field
The present invention relates to desalination plant technical field more particularly to a kind of low temperature multi-effect seawater desalting system spray gears
Plate.
Background technology
Low temperature multi-effect seawater desalting system is current international, the domestic mainstream technology scheme for carrying out sea water desalination water.System
The mode of system generally use " water-electricity cogeneration " distills out desalination water using generating set steam heating seawater.System utilizes power generation
Unit steam extraction is carried out at the same time and vacuumizes as the power vapour source of device, and seawater is made to be evaporated at 70 DEG C, the steam in heat exchanger tube
It is fresh water caused by system after cooling recycling after heat exchange.
Seawater is equably sprayed to top layer's heat exchanger tube top through water distribution system by seawater desalination system upper nozzle, with
In pipe while seawater to make heat exchange, ensures that heat exchanger tube has certain wettability, avoid fouling due to local water spray is few.Spray
Seawater from top to bottom, effect body support frame section bottom is flow to after the heat exchange of several heat exchanger tubes and is recycled to seawater side.Due to there is spray shelves
The effect of plate can prevent the part seawater in seawater spraying normal course of operation from splashing the demister side of next effect entrance and influencing
Seawater desalination system producing water water quality.Upper spray pipe is during spray, it is possible to there are nozzles crooked, spray tube fracture, spray
The reasons such as leaching system jams cause sprayed sea water mass flow discrepancy even or splash to dilute side by seawater side, influence producing water water quality and refer to
Mark.Once there is the above problem in system operation, there will be a large amount of fine grindings to splash product water side, causes production water power to lead super
Mark, it is serious to cause water supply network overproof water quality, and shutdown system is needed to be checked and repaired.
Although the prior art can play the role of antispray in normal course of operation, to imitating the proper flow of internal steam
It affects, " indirect steam " that evaporation of seawater generates can not flow directly to the entrance of next effect by plate washer side
Side needs around being mixed again with other " indirect steams " after plate washer, this virtually increases the flow resistance of gas, increases pumping
The burden of vacuum system.In addition, being made since baffle mostly uses etch-proof metal material, dead weight is larger, is repairing
Manual operation intensity is larger in journey.In case of spray system abnormal conditions, also can not promptly and accurately judge to imitate body support frame part
Inside spray abort situation, needs to open multiple manholes and is checked, increases equipment idle time and process cycle.
Invention content
In view of the above-mentioned problems, the object of the present invention is to provide one kind further decreasing seawater desalination system in the process of running
" indirect steam " vapour lock, mitigate overall weight, quickly confirm fault point, it is convenient to overhaul and safeguard low-temperature multiple-effect seawater desalination
System sprays baffle.
Technical solution is used by the present invention solves above-mentioned technical problem：A kind of low temperature multi-effect seawater desalting system spray
Baffle, including imitate body support frame part, multiple Y-shaped plate washers that protection screen and protection screen are internally embedded, the Y-shaped baffle
It is made of PVC material module, protection screen top is connect at effect body support frame part-structure by fixed card buckle, the baffle frame
Frame both sides are equipped with sliding rail, are used cooperatively with the sliding slot being fixed on effect body support frame part, the sliding slot lower part is equipped with limit
Pin, the Y-shaped baffle is mounted on universal wheel up and down, is fixed in the protection screen by the universal wheel, described " Y "
Type baffle lower part is equipped with tuning screw rod, and the protection screen lower part is set there are one catch basin, and the catch basin is drawn by pipeline
Go out and connects vacuum pipe pump.
Further, the catch basin is equipped with downflow weir, and the height of weir plate is less than " Y " font baffle bottom.
Further, water hole is designed at the Y-shaped baffle lower support, the drop that Y-shaped baffle shuts off passes through weight
Force effect flows downward, and is entered in water storage tank by water hole.
Further, it is connected with spinner flowmeter at the vacuum pipe pump discharge.
Further, the universal wheel is globular universal wheel.
The advantage of the invention is that：
1. by using light Y-shaped plate washer, " the secondary steaming of seawater desalination system in the process of running is further decreased
Vapour " vapour lock makes the steam that heating of seawater generates in effect body support frame part flow into next effect in time, avoids because bulk gas is in effect body
System heat transfer effect is poor caused by internal stops, steam poor flow quality and caused by efficiency decline, and reduce and vacuumize
The burden of system.
2. using the above design, system design input metal is few, and device overall weight mitigates, and is brought to overhaul and safeguarding
Convenient, maintenance greatly reduces.
3. using " buckle " formula fixed form and disassembly process centre mounted type modes of emplacement, worker's labour can mitigated by force
While spending, further shortens maintenance time, reduces space for maintenance occupancy, avoid the influence brought in transport and hoisting process.
4. plate washer die angle can be adjusted as needed, accomplish to imitate the dynamic of body internal gas flow resistance and spray flux
State is adjusted, and maximally utilises limited space.
5. plate washer module uses cheap material, cost further decreases, partial destruction and it is dirty respectively or part into
Row processing, corrosion-resistant and impact capacity are strong.
6. bottoms have spray water collecting device, can be for statistical analysis to its water in system operation exception, into
And judge that there are leakage events by its flow.Convenient for overhauling in time, the time of the solution of problem is reduced.
