Application number is that 200820025931.7 application for a patent for invention discloses a kind of natural ice-reserving ice maker, and its shortcoming is after 1. ice bank is carried out cold output, and the water of ice-out is if store, and the investment cost of water tank is very high; If run off in vain, can cause the waste of water resource; 2. along with the increase ice making speed of the outer ice layer thickness of heat pipe can be more and more slower.
Application number is that 200510009971.3 application for a patent for invention discloses a kind of natural ice cold accumulation air-conditioner, and its shortcoming is a 1. system complex, and the equipment investment expense is high; When 2. cold is exported, will ice from ice house and take out, and at the ice process chamber ice carried out fragmentation, and drop into the process in ice-melt pond, complex operation is inconvenient, wastes time and energy the operating cost height.
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 storage problem of the water behind the solution ice-out, avoids the waste of water resource.Three of the technical problem that solves is system's settings and simple to operate, to reduce investment outlay and manpower.
For solving the problems of the technologies described above, the present invention utilizes natural cooling source to carry out ice-reserving the mode that ice storage tank and underground water well are combined.Utilize the system of natural cooling source ice-reserving to form near the overflow returning pipe of the water injector at top, underground water well, water pump, water pumping pipe road, ice storage tank by the air flow passage at ice storage tank, ice storage tank top, ice storage tank the inside; The suction inlet of water pump is below the water surface of underground water well, and outlet is connected with the water injector of ice storage tank the inside near the top through the water pumping pipe road; Overflow returning pipe is as far as possible little from the distance at jar end, as long as the water of ice storage tank bottom can satisfy the requirement of cold energy output device; Overflow returning pipe leads in the underground water well, and behind the ice-out, remaining water is all got back to underground water well through overflow returning pipe except a small amount of water in bottom.When winter atmospheric temperature reduce to the freezing point of water when following, underground water is pumped at ice storage tank, successively spray and freeze, the storage cold; Other seasons, the ice-out Cheng Shui of storage flowed back to underground water well through overfall in the ice storage tank when carrying out cold output through the cold energy output device.Ice storage tank has only the function of ice-reserving and insulation, and not as water tank, so the manufacturing cost of ice storage tank reduces a lot.Ice-out Cheng Shuihou finally all flows back to underground water well, can not cause the waste of water resource.
For the sidewall that guarantees ice storage tank does not bear hydraulic pressure, on jar overflow returning pipe is housed, overflow returning 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 returning pipe does not bear hydraulic pressure, and the tank skin below the overflow returning 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.
Air flow passage is arranged at the top at ice storage tank, and guarantee the circulation of ambient atmosphere and ice storage tank interior air during ice-reserving winter.Can the top of ice storage tank be made movable form, open it during ice-reserving, utilize the free convection of air to come heat exchange.For the heat exchange of fortified water and atmosphere, also can take forced ventilation, adorn a ventilation blower in the top center of ice storage tank, some equally distributed ventilating openings are arranged all around; The air channel of ventilation blower and ventilating opening all have the air door that can open or close, and ice-reserving is closed after finishing.
The invention has the beneficial effects as follows that it is that investment is relatively low that a kind of system and method that utilizes the natural cooling source ice-reserving, characteristics are provided, and can not cause the waste of water resource; System is simple, and is easy to operate, and operating cost is few.
Because the sidewall of water tank will bear the pressure of water, wall thickness will calculate according to following formula:
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; [o] 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.
With the water of underground water well stamp come ice making during ice-reserving winter among the present invention, and summer, cold energy output back ice-out became water to flow to underground water well, can not cause the waste of water resource.
