Abstract

The utility model provides a same-well circular geothermal energy collecting device. The same-well circular geothermal energy collecting device comprises a well wall and a well casing, wherein the well casing is arranged inside the well wall; a conical precipitation tube is arranged at the bottom end of the well casing; a water filter tube is arranged on the side wall of the bottom of the well casing; a cavity formed between the well wall and the well casing is filled with quartz sand; a water return tube is positioned above a concrete cushion and is communicated with the cavity formed between the well wall and the well casing; a water supply tube is arranged inside the well casing; a submersible pump is arranged at the bottom end of the water supply tube; a plurality of flow guide tubes are uniformly distributed in the cavity formed between the well wall and the well casing along the circumferential direction; rubber isolating plates are arranged on the upper portions and the lower portions of the flow guide tubes; the cavity formed between the well wall and the well casing is partitioned into three segments through two rubber isolating plates; upper and lower segments are taken as heat exchange areas. The same-well circular geothermal energy collecting device has the advantages of small floor area, no consumption of underground water, safety and reliability in running, low cost, wide application range and high heat energy collection amount.

Description

With cyclically heat energy harvester of well

Technical field

The utility model relates to a kind of with cyclically heat energy harvester of well, belongs to air-conditioning system technical field.

Background technology

The energy collecting system of source, existing ground central air-conditioning mainly contains: one takes out many times type collection wells, underground pipe soil heat exchanger system, air, cooling tower, the following drawback of utilizing above-mentioned energy collecting system to exist: 1. occupied ground is large; 2. cost is high; 8. long-term use can not be recharged completely and be caused level of ground water to decline; 4. in using, produce and move sand, long-term use causes geology to subside; 5. conditional request harshness to external world, even can not move when winter temperature is extremely low as adopted cooling tower and air-source heating time; 6. energy acquisition efficiency is low, can not meet needs.

Utility model content

For the problems referred to above, the utility model provides cyclically heat energy harvester of a kind of novel same well.

The technical solution of the utility model: with cyclically heat energy harvester of well, comprise the borehole wall and well casing, well casing is placed in borehole wall inside, the bottom of well casing is provided with the sediment tube of taper, sidewall in well casing bottom is provided with filter pipe, in the chamber forming, is full of quartz sand between the borehole wall and well casing, return pipe above concrete cushion and with the above-mentioned borehole wall and well casing between the chamber that forms be communicated with, feed pipe is placed in the inside of well casing, and the bottom of feed pipe is provided with immersible pump; Be positioned at the medium position place of whole well casing, some mozzles in the chamber forming, have been uniformly distributed circumferentially between the borehole wall and well casing, the upper and lower of mozzle is respectively equipped with rubber division board, the chamber forming between the borehole wall and well casing is divided into three sections by two rubber division boards, and wherein epimere and hypomere are as heat exchange zone.

The beneficial effects of the utility model: source, the utility model utilization ground has substituted traditional cooling tower power-saving technology, the utility model not only can be applicable in central heating refrigeration system, but also can be used for big-and-middle-sized building energy conservation reduction of discharging or public building energy reduction of discharging, its concrete manifestation is as follows:

1 takes up an area less, only needs beat a glance production wells, can be placed on road, and in greenbelt etc., outward appearance is only seen a standard well lid;

The 2 environment friendly and pollution-free geologic structures of not destroying, this device only gathers the energy in underground water, does not consume underground water;

3 is safe and reliable to operation, in service without HTHP, moves without desilting for a long time, and totally-enclosed pipe-line system is corrosion-free;

4 costs are low, and a collecting unit can replace current one 4 wells for many times patterns, and cost reduces 40% relatively;

5 scopes of application are wide, all can apply this device in the area that underground water is poor;

6 one covering devices can provide the energy of 700KW, can supply the building refrigeration and heating of 8000m2.
