Description
Technical field
The invention belongs to air precooling technical fields, and in particular to be a kind of space division chilldown system.
Background technology
The flow of deep cooling oxygen space division chilldown system is at present：Recirculated water --- water-cooling tower --- refrigerating water pump --- refrigerator
Group --- air cooling tower --- distributor --- circulating water pool, due to containing calcium ions and magnesium ions in recirculated water, calcium ions and magnesium ions solubility with
Temperature is reduced and is declined, and when its concentration is higher than solubility at this temperature, calcium ions and magnesium ions, which will be precipitated, blocks distributor sieve pore,
Air cooling water distribution is uneven after distributor sieve pore blockade, and gas-liquid cannot fully exchange heat, and air themperature increases, in air
Water content increases, and influences the adsorption effect of drier molecular sieve, and carbon dioxide and hydrocarbon adsorption capacity decline, cause
The ice blockage of rectifying column main heat exchanger, space division system parking maintenance, and then bring about great losses to production enterprise, therefore empty
Chilldown system calcium ions and magnesium ions Crystallization Plugging problems demand is divided to solve.
Invention content
It is pre- so as to provide a kind of space division it is an object of the invention to solve the problems, such as calcium ions and magnesium ions Crystallization Plugging in the prior art
Cooling system.
The technical solution used in the present invention is：A kind of space division chilldown system including air cooling tower, chilled water system and follows
Ring water system, the air cooling tower middle part is equipped with distributor and air cooling tower is divided into air cooling tower epimere and air cooling tower by gas and water separator
Hypomere, the chilled water system carry out heat exchange for air cooling tower epimere, and the circulation carries out for air cooling tower hypomere
Heat exchange.
Preferably, the chilled water system includes air cooling tower epimere, and refrigerating water pump freezes unit, liquid seal trough, water-cooling tower, institute
It states water-cooling tower outlet with freezing pump inlet to be connected, the freezing pump discharge is connected with freezing unit import, and the freezing unit goes out
Mouth is connected with air cooling tower epimere import, and the air cooling tower epimere outlet at bottom pipeline is connected with liquid seal trough import, the liquid seal trough
Outlet conduit is connected with water-cooling tower inlet.
Preferably, the circulation includes circulatory pool and cooling pump, the air cooling tower outlet at bottom and circulatory pool into
Mouth pipeline is connected, and the circulatory pool outlet is connected with cooling pump inlet, the cooling pump outlet conduit and air cooling tower centre inlet
It is connected.
Preferably, the air cooling tower epimere outlet at bottom pipeline stretches into fluid-tight trench bottom, the liquid seal trough outlet conduit position
In its top.
The beneficial effects of the invention are as follows：（1）Middle part increases gas and water separator inside air cooling tower, plays following several big masters
It acts on：Air cooling tower epimere desalted water and hypomere recirculated water are separated as desalination water collecting device, prevent air cooling tower epimere by a
Calcium ions and magnesium ions fouling and clogging equipment and pipeline in cryogenic freezing water system；B makes air cooling tower hypomere high-temperature gas as gas passage
Smoothly it can continue to cool down into epimere；C is extra when epimere desalted water liquid level is more than setting value as desalted water overflow port
Desalted water can be overflowed in air cooling tower hypomere recirculated water.
（2）Increase a liquid seal trough for preventing from collaborating outside air cooling tower, the chilled water after heat exchange is led into water using pressure difference
The cold of the cold dirty nitrogen of tower recycling, chilled water-circulating pump boosting after the further cooling of freezing unit are sent and are followed at the top of air cooling tower again
Ring uses, and realizes desalted water closed cycle；
（3）The saturated vapour pressure of water is different under different temperatures, the high-temperature gas washed by recirculated water come from air cooling tower lower part
Water cooling is desalted on air cooling tower top, which part water vapour condenses the moisturizing as Desalting Water System, ensure that precooling system
The water quality of system chilled water solves the problems, such as chilldown system Crystallization Plugging caused by the raising of calcium ions and magnesium ions content in chilled water；
（4）Air cooling tower lower part high-temperature gas still using circulating water cooling, reduces the load and energy consumption of freezing unit.The project implementation
Afterwards, after use for many years, each parking checking handpiece Water Chilling Units evaporator tubulation, chilled water pipeline, air cooling tower distributor are not
There is crystalline polamer, transformation has reached design object and effect, achieved huge economic benefit.
Description of the drawings
Fig. 1 is the structure diagram of space division chilldown system of the present invention.
