Description
Technical field
The invention relates to the device for melting snow that utilizes underground heat to come melting road surface and roof accumulated snow.
Background technology
In the past, consideration be to utilize pump to draw underground hot water, spill device from accumulated snow to road surface etc. that locate to melt then.
This device utilizes original hot water to spill to the snow mask very high snow melt effect, and utilizes the hot water of nature can not produce the advantage of environmental problems such as atmosphere pollution.
Summary of the invention
But because original this device must utilize pump to draw geothermal water, and the also easy damage pump of the composition that is contained in this heat energy itself and the geothermal water, so contain inferior this problem of device durability.If use the good pump of heat resistance, will improve equipment cost.
Simultaneously, because original this device must draw underground hot water in large quantities, so can bring out the sagging such environmental problem of ground.
The present invention is in order to address the above problem, and provides that a kind of endurance quality is superior, snow melt is effective, and can not bring out the sink device for melting snow of such problem of atmosphere pollution and ground.
Solve the method for this problem
Describe referring to figs. 1 through Fig. 3.This utilizes the device for melting snow of underground heat about the present invention, is by being embedded vertically at underground heating device 1, and a non freezing solution that is circulating between heat interchanger 5 is gathered underground heat.And the underground heat that collects by heat interchanger 5, with the passing of the secondary non freezing solution that is circulating between the heat release pipe 6 that is provided with in heat interchanger 5 and snow melt place 10,10 devices that discharge this heat energy thawing accumulated snow in the snow melt place.Between the heating device of recording and narrating previously 1 and heat interchanger 5, be provided with toward road 8 and loop 9, on this loop 9, be provided with circulation pump 7 for a non freezing solution of recording and narrating is previously circulated in order to make a non freezing solution circulation of recording and narrating previously.
The specific embodiment
About the present invention this form of implementation of utilizing the underground heat device for melting snow as shown in Figure 1, this device is made of heating device 1, heat release pipe 6 and heat interchanger 5 several main parts.
Heating device 1 is to insert inner core 3 with concentric shape in by the urceolus 2 of bottom lock, and forms the concentric double tubular type object that gap path 4 constitutes between urceolus 2 and inner core 3, be embedded vertically at the degree of depth of underground 50m～100m.
Heat release pipe 6 can be laid on the snow melt place 10 that road surface and roof etc. need according to so-called hair clip shape.
For being circulated, a non freezing solution is provided with circulation pump 7 on the loop 9 of Ji Shuing in front.In this form of implementation, be connected with gap path 4 toward road 8, loop 9 is connected with inner core 3.
By such formation, start 7, non freezing solutions of circulation pump and flow down from the upper end by inner core 3, invade gap path 4 in its lower end upwards soaring.In soaring process, gather underground heat, a non freezing solution after the rising reaches heat interchanger 5 by loop 8.
Heat energy at 5, non freezing solutions of heat interchanger is transferred to by interchange of heat on the secondary non freezing solution that is circulating between the heat release pipe 6.By the secondary non freezing solution of interchange of heat heating, at heat release pipe 6 heat energy is discharged, thus 10 accumulations of melting accumulated snow or prevention snow in the snow melt place.
A non freezing solution that is seized heat at heat interchanger 5 offers heating device 1 once more and carries out the collection of underground heat via circulation pump 7.So move in circles, melt accumulated snow constantly in snow melt place 10.
This device for melting snow is gathered underground heat by a non freezing solution, utilizes this heat energy to carry out the snow melt operation.So realized with the hot water in the non freezing solution replacement conventional art by circulation pump 7.This time non freezing solution reduces the first mate than the temperature of the hot water that uses in the conventional art.And be provided with a non freezing solution that circulation pump 7 finishes interchange of heat once more by loop 9, make the temperature of non freezing solution this time lower than the temperature on past road 8.So circulation pump 7 does not break down with regard to not being subjected to the influence of ingredient in heat energy and the hot water.Consequently the durability of this device rises significantly.Meanwhile, can use general pump, reduce cost of investment.
Be provided with heat interchanger 5, give the secondary non freezing solution the thermal energy conduction of a non freezing solution, compared with the untouched way that offers heat release pipe 6 of non freezing solution different be that its temperature can not lowered the temperature rapidly at heat release pipe 6 places, but remains on certain temperature.Also can reach more than the required temperature of thawing accumulated snow so absorbed the temperature of the secondary non freezing solution of its heat, can keep snow melt effect long-time, continuation.
When carrying out snow melt, according to the difference in place, need to heat up rapidly at short notice, the situation that routinely remains on uniform temperature for a long time is more general.Apparatus of the present invention, be exactly on the basis of this understanding, be provided with heating device 1 and heat release pipe 6 and the heat interchanger between them 5, high temperature not necessarily, but to reach the necessary uniform temperature of snow melt with long-time and continuation.
In the time of need for a long time and expecting higher temperature, then can replace heat interchanger or heat interchanger and heat pump and install simultaneously with heat pump.
This utilizes geothermal device, because be the heat energy that utilizes the earth's crust itself, can not take place that ground sink and this advantage of problem such as atmosphere pollution so have.
Device for melting snow of the present invention except being used for the accumulated snow on melting road surface and roof, can also use as the heating equipment of floor heating.
This utilizes other form of implementation of underground heat device for melting snow about the present invention, as shown in Figure 2.The feature of this device is that as shown in Figure 1 form of implementation is just in time opposite, and a non freezing solution is to flow to inner core 3 from gap path 4.This device is also identical with above-mentioned device, has excellent in durability, does not have the advantage of problem generations such as atmosphere pollution, can reach the snow melt effect equally.
Heating device 1 also not necessarily only is confined to the concentric double pipe mode shown in this form of implementation, can also also can with U font pipe as shown in Figure 3.These U font tube body 13 middle bodies are provided with dividing wall 14, two passages 15 of parallel formation.
The effect of invention
This utilizes underground heat snow melt device about the present invention, be circulation pump 7 make low temperature once not Freeze liquid and pass through, because 9 be provided with 7, non freezing solutions of circulation pump and carrying out heat in the loop After the exchange, temperature can reduce again, so bring because of excess Temperature can not for circulation pump 7 Existing fault. So increased substantially the durable performance of this device.
Be provided with heat exchanger 5 between heating device 1 and the heat release pipe 6, because of the heat with a non freezing solution Can pass to the secondary non freezing solution, so that the temperature of secondary non freezing solution can reach snow melt is necessary More than one fixed temperature. Thereby can for a long time, routinely carry out effectively snow melt work.
This utilizes underground heat snow melt device, because utilization is underground heat, so can not bring out under the ground Fall into and the generation of the problem such as atmosphere pollution.
