Description

A kind of ice storage tank that utilizes the natural cooling source ice-reserving

Technical field

The present invention provides a kind of ice storage tank that utilizes the natural cooling source ice-reserving, belongs to refrigeration technology field.

Background technology

Utilize the natural cooling source ice-reserving, be meant the area that is lower than the freezing point of water in the wintry weather temperature,, make water freezing and store, utilize the fusion of ice to absorb heat when environment temperature is high by the time and freeze through the heat exchange of cold air and water.

Utilize the natural cooling source ice-reserving at present, mainly contain open-air modes such as embacle formula ice-reserving, laminated type ice storage tank and heat pipe-type ice-reserving.Wherein the subject matter of laminated type ice storage tank is: the one, and ice storage tank is simultaneously as water tank; The manufacturing cost of jar increases greatly; The 2nd, the ice at jar end thawing earlier often during ice-out, the ice that contacts with sidewall does not also melt, and the weight that ice body is huge can be damaged tank body.

Summary of the invention

The present invention is directed to above-mentioned prior art, one of technical problem of solution is the function that the ice-reserving container has only ice-reserving and insulation, not as the tank behind the ice-out, makes the manufacturing cost of ice storage tank reduce a lot; Two of the technical problem that solves is to guarantee when solving ice-out that the ice that contacts with sidewall melts earlier, avoids the huge weight of ice body to damage tank body.

For the sidewall that guarantees ice storage tank does not bear hydraulic pressure, on jar overflow pipe is housed, overflow pipe gets final product with the requirement that the water of bottom can satisfy the cold energy output device from the distance at jar end.Like this, the above tank skin of overflow pipe does not bear hydraulic pressure, and the tank skin below the overflow pipe only bears less hydraulic pressure.The cold energy output device can be a coil pipe, is installed in the ice storage tank bottom, be immersed in the water, and in the pipe cold water (or other media) forced circulation.The cold energy output device also can be simpler, and direct water with the ice storage tank bottom is pumped into and needs the refrigeration place, and the water that temperature raises after the heat exchange is got back to ice storage tank.

Ice-reserving is when beginning to melt in jar, and after preventing the ice-out at the bottom of the ice storage tank, an ice body weight causes damage to tank wall in jar on sidewall, must guarantee that the ice that contacts with sidewall at first melts.For addressing this problem, the side wall construction of ice storage tank be with a plurality of steel pipes as column, steel plate is welded on the column, steel plate external application heat-insulation layer, steel pipe both as the support of sidewall also as air flow passage.The upper orifice of all columns is connected with a female pipe of public ventilation, and lower nozzle also is connected with a female pipe of public ventilation, up and down two flowing between one of female Guan Geyou or several air doors control inner air tube and the ambient atmosphere of ventilating.Open air door and the always maintenance of column two ends public ventilation female pipe often open, through the free convection of column in air when beginning ice-reserving winter; Guarantee that side wall temperatures is consistent with atmospheric temperature; And conduct heat through the bottom sheets that welds together with sidewall, also keep lower temperature at the bottom of making ice storage tank, prevent to melt the ice through the underground heat that the basis of ice storage tank is transmitted; In order to reduce the underground heat that transmits through the basis of ice storage tank as far as possible, in the basis of ice storage tank heat insulation structural is arranged.When atmospheric temperature is higher than the freezing point of water, through natural or compulsory ventilation, make the ice dissolving that contacts with the ice storage tank sidewall, after the ice body that ice storage tank is inner and the sidewall of ice storage tank break away from fully, close the air door of the female pipe of the public ventilation in column two ends.

The invention has the beneficial effects as follows that it is that investment is relatively low that a kind of ice storage tank that utilizes the natural cooling source ice-reserving, characteristics are provided; Can not damage tank body in the ice-out process.

Because the sidewall of water tank will bear the pressure of water, wall thickness will calculate according to following formula:

${\mathrm{\δ}}_1=4.9\frac{(H-0.3)D}{\left[\mathrm{\σ}\right]\mathrm{\φ}}$

In the formula, δ 1 is the tank skin calculated thickness of store water medium, mm; H is the vertical range on tank shell base to the tank skin top of calculating, and D is the storage tank internal diameter, m; [σ] is the allowable stress of tank skin steel plate under the normal temperature, MPa; φ is a welded joint coefficient, gets 0.9 usually.

For example, make the cylindrical steel water tank of one 2 ten thousand stere, diameter 37m, high 20m, the consumption of steel are approximately 400 tons.Make the cylindrical steel ice storage tank of one 2 ten thousand stere, needn't consider the pressure-bearing of tank skin, the steel plate of wall thickness 2mm can meet the demands; And can design by the minimum mode of jar surface area, promptly diameter equals height, can obtain minimum steel consumption amount and minimum cold insulation material consumption; Steel plate adds that the consumption of the steel of support is approximately 140 tons, and the consumption of steel reduces greatly.
