Description
Technical field
The utility model relates to desalination plant technical fields more particularly to a kind of low temperature multi-effect seawater desalting system to spray
Drench baffle.
Background technique
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 that system generallys use " water-electricity cogeneration " distills out desalination water using generating set steam heating seawater.This system utilizes hair
The steam extraction of motor group while being vacuumized as the power vapour source of device, evaporates seawater i.e. at 70 DEG C, the steaming in heat exchanger tube
Vapour is fresh water caused by system after cooling recycling after exchanging heat.
Seawater is equably sprayed to top layer's heat exchanger tube top through water distribution system by seawater desalination system upper nozzle, with
In managing while seawater to make heat exchange, guarantees 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 which there are spray head skews, 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 powder-refining with waters 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 the proper flow for imitating internal steam
It affects, " secondary steam " that evaporation of seawater generates can not flow directly to the entrance of next effect by plate washer side
Side needs around mixing again with other " secondary steams " after plate washer, this virtually increases the flow resistance of gas, increases pumping
The burden of vacuum system.In addition, dead weight is larger since baffle mostly uses etch-proof metal material to be made, 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, increase equipment idle time and process cycle.
Utility model content
Seawater desalination system is further decreased in view of the above problems, the object of the present invention is to provide one kind running
" secondary steam " vapour lock, mitigation overall weight, low temperature multi-effect seawater desalting system convenient to overhaul and maintenance in journey spray gear
Plate.
The utility model solves technical solution used by above-mentioned technical problem: a kind of low temperature multi-effect seawater desalting system
Baffle is sprayed, including multiple Y-shaped plate washers that effect body support frame part, protection screen and protection screen are internally embedded, the Y-shaped
Baffle is made of PVC material module, and protection screen top is connect at effect body support frame part-structure by fixed card buckle, the gear
Plate framework two 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
Spacer pin, the Y-shaped baffle are mounted on universal wheel up and down, are fixed in the protection screen by the universal wheel, institute
It states Y-shaped baffle lower part and tuning screw rod is installed, the protection screen lower part is equipped with a catch basin, and the catch basin passes through pipe
Pass goes out and connects vacuum pipe pump.
Further, the catch basin is equipped with overflow weir, and the height of weir plate is lower than " Y " font baffle bottom.

Power effect flows downward, and is entered in water storage tank by water hole.
Further, spinner flowmeter is connected at the vacuum pipe pump discharge.
Further, the universal wheel is globular universal wheel.
Utility model has the advantages that
1. further decreasing " the secondary steaming of seawater desalination system in the process of running by using light Y-shaped plate washer
Vapour " vapour lock, the steam for making to imitate heating of seawater generation in body support frame part flow into next effect in time, avoid 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. system design investment metal is few, and device overall weight mitigates, and brings to overhaul and safeguarding using the above design
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, bring in transport and hoisting process is avoided to influence.
4. plate washer die angle can be adjusted as needed, accomplish to imitate the dynamic of body internal gas flow resistance and spray flow
State is adjusted, and maximally utilises limited space.
5. plate washer module uses cheap material, cost further decreased, 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 when system is operating abnormally, into
And by the judgement of its flow, there are leakage events.Convenient for overhauling in time, the time of the solution of problem is reduced.
