Description

[0001] The present invention relates to a capsule type submersible pump and a capsule type submerged pump,

The present invention relates to a submersible pump used for underground water, hot spring, and geothermal development, and more specifically, it is easy to install and maintain, and can effectively prevent water temperature from falling out of groundwater and hot spring water, To a capsule type submersible pump and its installation structure.

One of the essential elements of human survival is water, and in some areas it is still suffering from serious water shortages. In other words, water is an important resource and securing high quality water, especially used as drinking water, is becoming an important issue.

Numerous underground water is being developed and exploration for finding hot spring water is being carried out. In particular, Korea is also classified as a water-scarce country, and it is expected that research and development will be carried out in order to secure more and better quality water in the future.

Generally, it is necessary to drill hot springs deep underground in order to develop hot spring water compared with groundwater development. It is known that in Korea, it is necessary to descend to a depth of about 500 to 1000 m to obtain a hot spring water of about 25 to 40 ° C.

Unlike common sense, about 80% of Uranara hot springs are not able to use hot water immediately, but they are reheated. This is because the temperature of hot spring water itself is low, but during the process of extracting hot spring water, This is because the water temperature drops while passing through the head of the pump and the cold water layer (16 ~ 20 ℃) formed in the upper part of the hot spring.

Therefore, although the groundwater and the hot spring have been developed at a great cost, they have to reheat the groundwater and the hot water, which are costly and expensive to develop and use, thereby causing unnecessary energy waste and cost burden.

FIG. 1 attached is a construction diagram at the time of general hot spring water development.

As shown, the stratum structure is known to be formed from the land in the order of the normal topsoil 1, the weathering stratum 2, the soft rock layer 3, the caustic layer 4, and the polar rock layer 5 in this order. The hot spring water of 40 ℃ or more, which is enough to be used as hot spring water, can be obtained at a depth of about 1000 m or more near the undergrowth layer.

Therefore, in general hot springs construction, a main manhole 6 is formed in the topsheet 1, the main casing 7 is installed from the main manhole 6 up to the depth of the soft rock layer and the inner casing 8 ) To the middle of the carcass layer (4).

The hot springs are formed to a depth of about 1000 m or more, and the submersible pump 10 is normally installed at a depth of 500 to 800 m, which is approximately 80% of the depth of the digging through the inner casing 8. That is, the hot water is pulled out while the underwater pump 10 is connected to the lower end of the water pipe 20 inserted from the ground.

According to the conventional hot spring construction method, since the submersible pump 10 should be installed down to the depth of the hot water as much as possible, the total weight of the submersible pump is about 5 to 10 tons when the submerged pump is replaced / It is necessary to raise the whole underwater pump and related auxiliary materials to the ground by using a large crane, so that a large ground working area is required and a large maintenance cost is generated.

In addition, since the submersible pump 10 installed at a depth of the hot springs is exposed to water in the state without any protective film, there is a high possibility of breakage. Since the submersible pump 10 is operated on the wall surface, There is a problem that when the fracture crack layer and the soil or rock sludge fall off, the suction port of the submersible pump is closed or the normal operation is interrupted.

In addition, since the conventional water pipe is a single pipe, such as a stainless steel pipe, a white pipe and a general steel pipe, hot water drawn by the submersible pump 10 is subjected to a rapid water temperature lowering through the cold water layer, The temperature of the water is only about 24 to 30 占 폚. Therefore, there is a practical problem that additional cost is incurred and energy is wasted because the extracted hot spring water must be reheated using a separate heat source (gas, electricity, oil, etc.) and then supplied.

In addition, since the underwater pump is installed at a high degree of accuracy, high electric power is required to use the electric power, so there is a problem that a large amount of scale is generated inside the water pipe and regular cleaning or replacement work is required.

In the present invention, it is not necessary to lower the submersible pump 120 down to the bottom of the hot spring, and the submersible pump should be installed in the vicinity of about 200 to 400 meters below the water level. In the present invention, since the suction pipe 300 is made of synthetic resin, the overall weight of the suction pipe 300 can be drastically reduced. Therefore, a large-sized crane is not required to be installed, and the capsule type submersible pump 100, A compact crane and a cylindrical type speed reducer can be used to take out the vehicle, thereby achieving cost reduction.

In the present invention, when the submersible pump 120 is operated, the hot water is directly drawn out through the lower end of the suction pipe 300, so that there is no direct contact between the cold water bath and the hot spring water, and hot water at a high temperature can be directly extracted and used.

In addition, since the discharge pipe 500 has a double pipe structure, it is possible to prevent a sudden temperature drop due to the cold water during the extraction of the hot water, thereby avoiding reheating of the extracted hot water.

The present invention is a technology suitable for use in the development of ground water, hot spring water, and geothermal water.
