no. 1 approach

[0018] First implementation: see Figure 1-2 , a double-tube heat exchanger used in geothermal wells, including a heat exchanger body 1, the top of the left side of the heat exchanger body 1 is fixedly connected with an inlet pipe 2, and the left side of the inlet pipe 2 is fixed by a first gasket 3 Connected with the first connecting flange 4, the inner wall of the inlet pipe 2 is movably connected with a filter 5 used in conjunction with it, and the left side of the filter 5 is fixedly connected with a symmetrically arranged operating handle 19. By setting the operating handle 19, the It is more convenient for the staff to operate the filter 5. The top and bottom of the filter 5 are fixedly connected with a symmetrically arranged slider 6, and the top and bottom of the inner wall of the inlet pipe 2 are provided with a chute 7. The side of the slider 6 close to the chute 7 runs through the chute 7 and extends to the inside, the side of the slider 6 far away from the filter 5...

no. 2 approach

[0021] The second embodiment: a double-tube heat exchanger used in geothermal wells, including a heat exchanger body 1, the top of the left side of the heat exchanger body 1 is fixedly connected with an inlet pipe 2, and the left side of the inlet pipe 2 The side is fixedly connected with the first connecting flange 4 through the first sealing gasket 3, and the filter 5 used in conjunction with it is movably connected on the inner wall of the inlet pipe 2, and the top and bottom of the filter 5 are fixedly connected with Symmetrically arranged sliders 6, the top and bottom of the inner wall of the inlet pipe 2 are provided with chute 7, the side of the two sliders 6 on the same side near the chute 7 runs through the chute 7 and extends to the inside, The side of the slide block 6 away from the filter 5 is provided with a limiting groove 8, the inner wall of the limiting groove 8 and the side close to the filter 5 are fixedly connected with the limiting plate 10 through the limi...

no. 3 approach

[0033] The third embodiment: a method for quickly replacing filters in a double-tube heat exchanger in a geothermal well, the double-tube heat exchanger includes a heat exchanger body, and the sides of the heat exchanger body are fixed in sequence It is connected with the inlet pipe and the return pipe that constitute the circulating water heat exchange system, and a filter is movably clamped in the inner wall of one of the inlet pipe or the return pipe to filter the circulating water. The filter passes through the outer contour up and down A plurality of sliders arranged on both sides slide back and forth in the tube body. The sliding is performed by manually pushing and pulling the push-pull handle on the side of the outer contour of the filter away from the heat exchanger body. There are the same number of card slots as the sliders; a second handle that can slide up and down is arranged in each of the card slots. Each slider is snapped into or disengaged from the card slot ...

Abstract

The invention discloses a quick filter replacement method for a double-tube heat exchanger in a geothermal well. When the pipe body of the circulating water system is blocked, each second handle is pressed sequentially, and the second handle drives the movable plate to the The top of the block is squeezed, so that the block elastically compresses and breaks away from the slot. When the block moves to half the range of its sliding path during the compression process, it is attracted by the matching magnet on the path. At this time, the block It is adsorbed and stagnant in a compressed posture. At this time, the slider where the clamping block is located can slide freely in the tube body. Finally, the operator pulls the handle from the side until the filter is slid out of the tube body, realizing a convenient The dredged geothermal well uses a double-tube heat exchanger, which is more convenient to dredge the heat exchanger during use, which not only reduces the labor intensity of the staff, but also greatly improves the heat exchange effect of the heat exchanger.

Description

technical field [0001] The invention relates to the technical field of heat exchangers, in particular to a quick replacement method for a double-sleeved heat exchanger and an inner filter used in geothermal wells. Background technique [0002] A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid, also known as a heat exchanger; a heat exchanger is an energy-saving device that transfers heat between materials between two or more fluids at different temperatures , is to transfer heat from a fluid with a higher temperature to a fluid with a lower temperature, so that the temperature of the fluid reaches the index specified in the process to meet the needs of the process conditions, and it is also one of the main equipment to improve energy utilization. [0003] In recent years, with the strengthening of environmental protection awareness, the need for energy saving and emission reduction and the development of renewable energy, the utiliza...
