High-pressure extrusion process, the water containing higher proportion in the wet base that preceding working procedure transfer comes during thermocompression forming, in hot pressing
Under the high-pressure extrusion power of die material of sizing station, necessarily have substantial amounts of water vapour and produce and it needs to vacuum pump source system
Strong pumping under be transferred out, with shorten thermocompression forming be dried time with improve crosslinking curing efficiency.Paper moulded
Producing typically in thermocompression forming station is true using the higher water ring of simple and practical efficiency by the vacuum source that steam aspirates away
Empty pump.Water ring vacuum pump is to reach higher vacuum, typically constantly need to fill into a certain amount of in running in the pump housing itself
Water, make gap between the impeller of pump and pump case form sealing water ring because of the water constantly filling into, this is also so by this pump
The reason appellation water ring vacuum pump.
Under high vacuum environment, the gasification temperature of liquid can substantially reduce.Generally water ring vacuum pump manufacturer all can be to the pump housing
The temperature supplementing water is made stipulations, and typically may require that water temperature is less than 35 DEG C, requires optimal supply water temperature can be 15 DEG C.But problem
The temperature being thermocompression forming mould in Paper moulded production process can be at 180 DEG C 200 DEG C, and some mould temperature even can reach 230 DEG C
Left and right, the air themperature being pumped out by negative pressure of vacuum by force under this working condition also can be at 110 DEG C -130 DEG C about, so
High air themperature is once inhaled into water ring vacuum pump, can heat up being inhaled into the liquid serving as sealing water ring and gasify, produce
Give birth to so-called " cavitation erosion " phenomenon.Liquid can be made to rise because endothermic gasification becomes volume in steam process drastically to splash when cavitation erosion is formed, reason
More than 1700 times can be increased by volume during upper each cubic centimetre water, gasification as blast for the liquid can make pump case quilt
Impact into pit one by one, damage the pump housing, the vacuum in vacuum system also can be made simultaneously drastically to decline, reduce vavuum pump

Before empty pump, configure a set of air-cooling apparatus.But the weak point thus brought is：First, increased equipment investment expense；2nd,
Increased energy resource consumption；3rd, complicated cooling line configuration can make vacuum draw pipeline produce very big pressure, reduces vacuum
Suction capactity.Paper moulded has in the industry using clearance type heat-exchangers of the plate type as the cooling to hot-air, and in actual motion, this is cold
But the pressure differential of the air ports of device reaches more than 0.035Mpa unexpectedly, significantly reduces the energy of negative pressure of vacuum air inducing humidity discharging

Specific embodiment
With reference to the accompanying drawings and examples the structure and operation principle of the present invention is described in further detail.
The purpose of the present invention is to propose to a kind of air atomizing cooling tank and its air atomizing cooling technique, using high-pressure atomization
Application in pulp moulding vacuum suction dried system for the falling temperature technique, to avoid in Paper moulded thermocompression forming dry run by water
The overfire air that ring vacuum pump pumps out affects the normal operation of vavuum pump itself.
Related data explanation：The heat absorption of every gram of evaporation of water can make every cubic metre of about 2 degree of air cooling-down, theoretically,
Energy needed for mist cooling is the energy required for overcoming the surface tension of water to increase, and 1 kilogram of water becomes 10 microns vertical
During cube, energy about 43.200J required for its surface tension, and evaporation latent heat is up to 2.2MJ.The space environment fall of artificial fog
Warm principle is aerosol double fluid, evaporation endothermic, cooling terminal by a footpath 1-10 micron mist particles diffusion to the region that lowers the temperature, expanding
Constantly evaporate in scattered process, and absorb a large amount of heat energy in this region.The boiling point of liquid depends on residing pressure.Reduced pressure,
Boiling point declines, and so that mutual gravitation is reduced because air pressure is low, distance increases between gaseous molecular, molecule is more easy to escape.Pressure liter
Height, boiling point rises, because molecule increases and more difficult effusion apart near, mutual intermolecular attraction.In 7000 meters about of air pressure about
For the half on sea level, i.e. 0.5Kgf/CM2(about 49050Pa), so heating up water on the summit in Mountain Everest, as long as burn 72
Degree left and right water will seethe with excitement.The latent heat of vaporization of water is 2263.8J/g, and that is, each gram of water can absorb heat in critical undergoing phase transition
2263.8 joules of amount, and one gram of water is heated to during 100 degree of hot water by normal temperature and simply absorbs about 500 joules of heat.
In order to problem is better described, some physical phenomenons are made an analysis interpretation at existing examination by us：Can using evaporation endothermic
So that surrounding turns cold, thus reaching the purpose of refrigeration.State change between gaseous state and liquid：Between object molecule, distance is not
With.Evaporation and boiling phenomenon are all the vaporescences of liquid, and evaporation all can carry out at any temperature but evaporate simply in liquid
Body surface face is carried out, also heat to be absorbed during evaporation.Boiling is that fluid temperature reaches boiling point and continues to absorb heat under a certain pressure
Amount, the phenomenon acutely vaporizing on surface and liquid internal, i.e. boiling is carried out with outside in liquid internal simultaneously, and boiling also can
A large amount of absorption heats.Vaporization heat absorption, liquidation exothermic reaction.So evaporation and boiling the two between similarities and differences be：
(1) identical point：Evaporation is all vaporization phenomenon with boiling, is required for absorbing heat.
(2) difference：
A, scene are different：Evaporation is the vaporization phenomenon only occurring in liquid surface, and seethe with excitement be in liquid internal and
The simultaneous violent vaporization phenomenon in surface；
B, temperature conditionss are different：Evaporation can occur at any temperature, and seethe with excitement and occur at a certain temperature；
C, temperature change may be different：Heat need to be absorbed, temperature may reduce during liquid evaporation；And absorb in boiling process
Heat, but temperature keeps constant；
D, severe degree are different：Evaporite ratio relatively relaxes, and it is very violent to seethe with excitement.
E, influence factor are different：The temperature of evaporation speed and liquid, surface area, surface speed air flow relevant, boil
Rise boiling point relevant with the height of atmospheric pressure.Vaporization heat absorption is exactly vaporization heat absorption；Liquidation exothermic reaction is exactly that heat is discharged into object
In.
After analysis, we can show that related and useful some is enlightened to above-mentioned various information：
1. object can absorb in phase transformation or discharge substantial amounts of heat.
2. liquid evaporation, all carrying out at any temperature, but simply occurs on surface.
3. the boiling point of liquid depends on residing pressure.
4. the hydrone particle after high-pressure atomization can be significantly greatly increased the contact area with surrounding air, can improve liquid quilt
After atomization, endothermic disintergration becomes speed and the efficiency of steam.
The water that have impact on vacuum pumping source because air themperature is too high for current Paper moulded thermocompression forming vacuum pick-up system
The normal operation present situation of ring vacuum pump, is inspired by above-mentioned various information, through analysis it is considered that：As long as in vacuum draw pipeline
In set up an air atomizing cooling tank, in the space of this cooling tank, under the hot-air of excessively stream acted on by high-pressure water mist, high pressure spray
Enter the atomized water of a small amount of (appropriate), the quick contact area increasing liquid and hot inside air can instantaneously be absorbed heat vaporization, that is,
Can be in the negative pressure of vacuum that oneself so exists originally, higher temperature environment, atomized water instantaneously can produce phase transformation and completely vaporize, and inhale
Receive substantial amounts of heat, reach the suitable purpose reducing the air themperature in vacuum pick-up system, so that the hot-air of extraction is reached true
" cavitation erosion " phenomenon will not be produced during the water ring vacuum pump in empty source, and be smoothly discharged outside pump.
What one of key point of above-mentioned mist spray desuperheating technology was that high pressure sprays into is the fine particle shape water being atomized completely
Mist；The contact area that a diameter of micron-sized hydrone fine particle can be significantly greatly increased hydrone and air is can reach after atomization,
Make its can quick substantial amounts of heat in absorption air, create a liquid by being atomized the necessary requirement turning vaporization.So as high
The pressure of the high-pressure hydraulic pump of high pressure pumping source of pressure atomization is higher, and the aperture of high-pressure atomization shower nozzle is less, the mist being formed under its high pressure
The material changing water smoke is more tiny；The hydrone particle being formed after high-pressure atomization is more tiny, hydrone particle surface and air contact
Area is bigger, then more quickly and efficiently can change into steam by absorbing and cooling temperature under negative pressure of vacuum environment.The air atomizing of the present invention
Cooling tank is that the atomization of water under high pressure creates a suitable environment and indispensable condition with the cooling of excessively stream gas.
The two of the key point of above-mentioned mist spray desuperheating technology be above oneself spraying into of referring to should be " the atomization of a small amount of (appropriate)
Water ".Substantial amounts of water smoke really can absorb more heats, but the water smoke of excess can expand a lot of times after vaporization, can offset and shadow
The former vacuum that oneself sets up of Xiangshui County's ring vacuum pump, quickly aspirates with by the vapor of volume in die cavity during thermocompression forming
Out it is not inconsistent with the original intention of improve production efficiency at all.So the quantity of high-pressure atomization shower nozzle is not The more the better, Ying Shishi
Degree, it is relevant with the flow in the unit interval of excessively stream cooled hot-air.
Hot-air itself due to being sucked out from thermocompression forming station may have part vapor and condensed water,
Also have a small amount of liquid during atomization and vaporization in the air atomizing cooling tank of the present invention to remain, in order to not make this portion
The dischargeable capacity of tank body is taken, so the bottom cooling down tank body in high-pressure atomization is provided with excessively stream drain trap after part liquid water accumulation.
The upper and lower of this excessively stream drain trap is respectively provided with line with rubber wafer type Pneumatic butterfly valve, and ensures this upper and lower two pneumatic butterfly by control program
Valve will not open (one open before, another first must be made just can to carry out after completely closing) simultaneously, not make air atomizing cold
But the vacuum sealing environment of tank is destroyed and affects normal operation.
Hot-air itself due to being sucked out from thermocompression forming station may be entrained with long-pending in the operation that works before this
Leave incrustation scale, debris rubbish etc., such foreign matter can cause pump housing pump leaf to damage after being such as freely accessible in Water-ring vacuum pump housing, institute
