Description

Keeping warm PE water tank with durability to high temperature}

If you want to purchase water tank products such as 1ton, 3ton, 20ton, etc., which have heat retention and durability against long-term preservation of water of about 80 ° C or more, in the market or in a company that makes thermal insulation buckets, It's very hard to find, and also unsatisfactory, but similar performance products are very expensive.

Large capacity thermal water tank with excellent performance can be used for various purposes, and by using hot water which is stored for a long time in winter, you can take a shower very conveniently without needing additional heating, and can use it usefully for heating. There is an advantage.

In particular, if the hot water produced in the solar heat collector can be stored for a long time, it can be stored without a large amount of oil in the sun, and used for heating when it is cold.

In addition, if the heat storage capacity of the firewood boiler, which has a small heat storage capacity and can be easily cooled, is stored in a separate large-capacity hot water tank when heated, and used for heating, the heating energy due to the use of oil or electricity can be greatly reduced. As it contributes to the reduction of substances and carbon dioxide, it is believed that the conservation of the earth's environment will contribute.

The present invention relates to a water tank for keeping warm between about 1 to 30 tons having a durability against temperature and a heat retention in storing water of about 80 [° C.] in a water tank.

The present invention relates to a method of manufacturing a thermal insulation bucket of a new type that can be widely used by increasing the thermal insulation strength and the durability against temperature by using a PE (polyethylene) water tank manufactured by an integral molding method of about 30 tons or less that is produced in the past. .

The capacity of hot water tanks, such as hot water tanks of solar panels and firewood boilers, will generally depend on the calculation of the heat capacity stored, but given the expansion of collector panels, long-term storage of warm hot water in the sun, and cooling firewood boilers, A large capacity hot water tank is needed.

Large-capacity water tanks ranging from tons to hundreds of tons are mostly assembled and used for industrial purposes. Heat-resistant FRP or high-density PE incorporating urethane as a thermal insulation material is used, but they are expensive due to the use of materials that can maintain high temperatures for a long time. It is not suitable to be used universally.

The large water tank for late night electricity uses a hot water capacity of about 2.7 tons for 35 [Kw], and a hot water tank of about 1 ton is used for the installation of 10 heat collecting plates of 1 [m] length and 2 [m] length in solar heat. .

In general, these materials are used to make thermal insulation buckets of several tons or less used in late-night electricity, firewood boilers, and the like. The use has a very heavy drawback, and the price is not comparable to the capacity, and such a manufacturing method may not be practical to make a larger capacity water insulated tank.

PE (polyethylene), a water tank material that has been widely used in the past, has a heat resistance temperature of 80 [deg.] C and a deformation temperature of 85 [deg.] C, and can be used from -40 [deg.] To 100 [deg.] C. It is known to deform | transform when it exceeds [degreeC], and it is known that the water tank for FRP thermal insulation has the same problem.

The present invention is to solve the problem of the water tank for thermal insulation that is conventionally used, by using a PE (polyethylene) water tank that is produced by the integral molding method that is shipped as a conventional product from about 1 to 30 to about, heat insulation characteristics and It is a development of a new thermal water tank which greatly improves the durability against temperature and can be used universally in terms of price.

The thermal PE water tank with high temperature durability made by this new method has excellent features in terms of heat insulation and temperature durability compared to the existing thermal water tank products, and it has hot water and cold water. Since it can be widely used for heating, it is expected to contribute to the saving of oil or electric energy.

In our lives, hot water is also needed in winter, spring, autumn and summer, and is very convenient for heating in residential and horticultural houses and in various places such as showers.

The problem to be solved in the present invention is to improve the thermal insulation of water tanks for long-term storage of water of 80 [° C.] or more, in particular, about 1 ton that can be used for heating since deformation of the water tank does not occur at a storage temperature of 80 [° C.] or more. In the development of thermal water tank up to about 30ton.

This thermal water tank can be used for long-term preservation and use of hot water produced in large-scale solar panels, and provides a condition for storing and using waste heat that is temporarily concentrated or discarded by a coal fired boiler. It will greatly contribute to savings.

Insulating water tank of the present invention is to solve the durability and insulation for temperature by using a space generated by embedding one water tank of a slightly smaller size and the same shape in one large water tank.

The present invention uses two large and small water tanks of the same shape, and uses the space between the large water tank and the small water tank, which occurs when the small water tank is embedded in the large water tank, to improve the heat resistance durability, It is to develop a thermal water tank with characteristics that can be widely used compared to the tank capacity.

A thin steel plate is glued to the outer side of the wall of the small water tank, which is embedded in the large water tank, and the surface of the iron plate is glued, and then the long length of the bend is wrapped several times to increase the durability against temperature. Attach the iron plate and attach high density styrofoam onto the iron plate.

When a small water tank is embedded in a large water tank, a space is created between the large water tank wall and the small water tank wall, and the space is filled with insulation such as injection of polyurethane urethane foam or urethane sponge.

The interval between the water tank wall and the wall is selected approximately 10 [cm] interval, and can be added or subtracted as needed. When the thermal water tank is completed, an appropriate number of water inlets and oil outlets are created and used.

The internal method is to cut the upper part of the large water tank, insert the small water tank, and then fix the upper part of the cut large water tank back to its original position. If the inlet of the small water tank is small, the upper part of the small water tank is also cut off to perform the work.

For later repair, fill the polyurethane foam only under the cut line on the top of the small water tank and fill the urethane sponge from the top of the cut line on the small water tank to the inlet of the large water tank.

The average annual heat energy received on the surface of Korea's 1 [m] × 2 [m] area is 6000 [㎉], which is about 7 [] h] in terms of electricity, and 1 [ton] of water is about 6 [Degree C] can be raised.

If 15 facilities of 1 [m] × 2 [m], the standard size standard of solar panels in Korea, are installed, it can raise 1 [ton] of water 90 [℃] for a day, and about 100 [㎾h ], If the boiler can use about 9000 [㎉] of heat for 1 [ℓ] of oil, it is equivalent to 10 [ℓ] of oil, which is the amount of oil capable of heating 25 pyeong of the dwelling.

If the infinite solar heat energy reaching the surface is made of hot water and then stored in a large, well-insulated and undeformed hot water tank in a large amount, one million households can save 10 million liters of oil per day, If used for 100 days, it can save you 1 billion liters.

In addition, a large amount of waste heat that is temporarily fired or discarded, such as a wood boiler or briquette boiler, may be stored and used in a large-capacity hot water tank.

In addition, if the water in the 15 [° C.] thermal water tank, which is continuously stored by geothermal heat exchange in summer, can be used continuously, it can serve as a refrigerant without cooling it, so that it can Can save energy of cooling.

As described above, the thermal insulation PE water tank having durability against high temperature according to the present invention can conveniently use heating, cooling, and hot water using natural energy.

In addition, the solar heat collecting plate has a very high efficiency compared to a solar cell having a relatively low efficiency, that is, if the photoelectric conversion efficiency of a commercial photovoltaic system is 10 [%], it is 0.1 [㎾] to 1 [m] × 1 [m]. ] Is the rated capacity, so the rated capacity of 1 [m] × 2 [m] for comparison with solar heat is 0.2 [㎾].

Since the average amount of time the sun shines on the ground is 3.84 hours per day per year, the amount of electricity generated per day is less than 1 [m] × 2 [m] to 1 [㎾h], so there is very little loss in heat storage. Assuming, the photovoltaic power generation system has an efficiency of 20 [%] or less as compared with the solar heat collecting device 7 [mAh] calculated by the amount of electricity.

Therefore, in the current situation, if a large-capacity thermal water tank is used for an inexpensive solar collector, it is more than five times more efficient than a solar power system, and thus, it is expected to greatly contribute to the reduction of fossil fuel and prevention of warming.

The present invention is to store hot water or cold water, and to use hot water and air-conditioning, in particular, the heat-resistant PE (polyurethane) having excellent durability against deformation even after long-term storage at a temperature of 80 [° C.] or more and excellent thermal insulation properties. Ethylene) as a method for producing a water tank,

The thermal water tank uses two PE (polyethylene) water tanks, which are manufactured by the integral molding method, which is shipped as a product from about 1 to 30 tons. By incorporating a tank, the space generated between the wall of the large water tank and the wall of the small water tank is used to enhance the durability and insulation properties against temperature.

A thin steel plate is bonded to the outer side of the small water tank wall by an adhesive which can be used above 100 [° C.], the adhesive is applied on the bonded steel plate, and the long length of the bend is wound several times to increase the durability against temperature. The outer side of the bottom is bonded to the iron plate and high density styrofoam in order.

As mentioned above, the small water tank with increased durability against temperature is put in the large water tank with the upper part cut and removed, and after the small water tank is built, the cut upper part of the large water tank is combined into its original position. Space between the large and small water tank walls is filled with insulation, such as polyurethane foam or polyurethane sponge, and then creates the necessary water inlet and oil outlet.
