Description

Technical Field

[0001] This utility model relates to the technical field of heat exchangers, specifically a graphite heat exchanger filtration device. Background Technology

[0002] A graphite heat exchanger is a heat exchanger whose heat transfer components are made of graphite. The graphite used to manufacture the heat exchanger should be impermeable. Impermeable graphite and pressed impermeable graphite are commonly used.

[0003] The existing technology has the following problems:

[0004] 1. Graphite heat exchangers tend to accumulate a lot of dust inside during use. If the dust is not cleaned, it can cause blockage inside the heat exchanger, making it unusable or even damaging.

[0005] 2. After the dust is filtered out, the water inside the tank becomes contaminated with dust, usually requiring the water to be replaced, which increases the cost of use and wastes water resources. Utility Model Content

[0006] The purpose of this invention is to provide a graphite heat exchanger filtration device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A graphite heat exchanger filtration device includes a graphite heat exchanger, a filter box fixedly connected to the graphite heat exchanger, two sets of sealing partitions fixedly connected inside the filter box, a water inlet trough between the two sets of sealing partitions, a first water inlet pipe fixedly connected inside the water inlet trough, a water outlet pipe installed at the bottom of the graphite heat exchanger, a connecting pipe fixedly connected between the water outlet pipe and the first water inlet pipe, and a first water pump fixedly installed inside the connecting pipe.

[0009] A fixed cylinder is fixedly connected between the two sets of sealing partitions. A filter element is installed inside the fixed cylinder. An upper cover is fixedly installed on the filter box. A second water inlet pipe is fixedly connected to one side of the upper cover. A second water pump is installed on the second water inlet pipe. A discharge port is fixedly connected to the other side of the upper cover. A pressure valve is installed inside the discharge port. A one-way valve is fixedly connected inside the partition on the side of the partition near the upper cover.

[0010] The filter box is equipped with an exhaust assembly for discharging the gas in the heat transfer fluid.

[0011] As a further embodiment of this invention: a polymer membrane is installed at the bottom of the filter box to filter out air bubbles in the heat transfer fluid.

[0012] As a further embodiment of this utility model: the exhaust assembly includes a fixed cover fixedly connected inside the upper end cover, and an exhaust pipe is fixedly connected to the fixed cover.

[0013] As a further improvement of this utility model, a steam-water separator is fixedly installed inside the fixed cover.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model achieves circulation and pressure regulation of the heat transfer fluid through the coordinated work of the first and second water pumps, ensuring filtration efficiency; when the filter element efficiency decreases, the second water pump pressurizes and pushes impurities and excess heat transfer fluid through the pressure valve to discharge them without stopping the machine, significantly improving the continuous operation capability of the equipment; at the same time, this utility model effectively filters out air bubbles in the heat transfer fluid through the polymer membrane at the bottom of the filter box, and the rising gas is separated by the steam-water separator and discharged through the exhaust pipe, avoiding gas accumulation that could lead to abnormal system pressure, thus improving the practicality of the equipment.

Detailed Implementation

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] See Figures 1-3 In this embodiment of the utility model, a graphite heat exchanger filtration device includes a graphite heat exchanger 1, a filter box 2 fixedly connected to the graphite heat exchanger 1, two sets of sealing partitions 4 fixedly connected inside the filter box 2, a water inlet trough 5 provided between the two sets of sealing partitions 4, a first water inlet pipe 7 fixedly connected inside the water inlet trough 5, a water outlet pipe 6 installed at the bottom of the graphite heat exchanger 1, a connecting pipe 8 fixedly connected between the water outlet pipe 6 and the first water inlet pipe 7, and a first water pump 9 fixedly installed inside the connecting pipe 8.

[0021] A fixed cylinder 11 is fixedly connected between the two sets of sealing partitions 4. A filter element 12 is installed inside the fixed cylinder 11. An upper end cover 3 is fixedly installed on the filter box 2. A second water inlet pipe 13 is fixedly connected to one side of the upper end cover 3. A second water pump 14 is installed on the second water inlet pipe 13. A sludge discharge port 15 is fixedly connected to the other side of the upper end cover 3. A pressure valve 16 is installed inside the sludge discharge port 15. A one-way valve 10 is fixedly connected inside the partition on the side of the partition near the upper end cover 3. An exhaust assembly is installed inside the filter box 2.

[0022] This invention first uses a first water pump 9 to draw the heat transfer fluid from the graphite heat exchanger 1 and inject it into the inlet tank 5 along the connecting pipe 8 and the first inlet pipe 7. Then, the hydraulic pressure in the inlet tank 5 increases, thereby pushing the one-way valve 10 to open. The heat transfer fluid in the inlet tank 5 passes through the one-way valve 10 and enters the upper end cover 3, and then into the fixed cylinder 11. During this process, impurities in the heat transfer fluid are filtered by the filter element 12. The filtered impurities are stored in the upper end cover 3. As the amount of impurities increases, the filter element 12... As the filtration efficiency gradually decreases, more heat transfer fluid can then be pumped into the upper cover 3 via the second water pump 14 through the second inlet pipe 13. At this time, the hydraulic pressure inside the upper cover 3 continues to increase. The one-way valve 10 prevents the heat transfer fluid inside the upper cover 3 from flowing back. At this time, the pressure valve 16 is opened under pressure, and the impurities and excess heat transfer fluid inside the upper cover 3 are discharged through the discharge port 15. This achieves non-stop impurity removal of the equipment. Furthermore, this invention can also discharge the gas in the heat transfer fluid through the exhaust assembly.

[0023] In one instance of this embodiment, please refer to Figures 1-3 The exhaust assembly includes a fixed cover 17 fixedly connected inside the upper cover 3, an exhaust pipe 20 fixedly connected to the fixed cover 17, a steam-water separator 18 fixedly installed inside the fixed cover 17, and a polymer membrane 19 installed at the bottom of the filter box 2 to filter out air bubbles in the heat transfer fluid.

[0024] The exhaust assembly first filters out air bubbles in the heat transfer fluid that enters the graphite heat exchanger 1 from the filter box 2 through the polymer membrane 19. At this time, the heat transfer fluid enters the graphite heat exchanger 1, while the air bubbles remain in the filter box 2. Then, the small air bubbles form large air bubbles, which rise through the filter element 12 under the action of buoyancy and into the upper end cover 3. Then, gases such as oxygen and carbon dioxide pass through the steam-water separator 18 and are discharged along the exhaust pipe 20.
