Description

Technical fields:

[0001] This utility model relates to the field of condensation equipment technology, and more specifically to a condenser device for furnace cooling. Background technology:

[0002] In existing high-temperature carbonization furnaces or some heat treatment furnaces, condensers are generally used to cool the internal gas during operation. However, existing condensers only cool the gas. Since the gas in high-temperature carbonization furnaces or some heat treatment furnaces contains other substances, condensed water or oil will be produced after cooling. Existing condensers do not have a pipeline structure to drain the cooled water or oil. Generally, a through hole is set in the side plate of the shell and a plug is screwed on. After a certain period of use, the plug is usually removed manually for manual discharge. This method is ineffective, inefficient, and cannot be handled in real time, so the results are not ideal. Utility model content:

The heat exchange body 10 includes an upper shell 11 and a lower shell 12. Multiple outer tubes 13 and multiple inner tubes 14 are located between the upper shell 11 and the lower shell 12. The inner tubes 14 are inserted into the corresponding outer tubes 13.

The edge of the top plate of the upper housing 11 and the edge of the bottom plate of the upper vent housing 30 are fixedly connected by bolts. A central through groove is formed in the middle of the bottom plate of the upper vent housing 30. The central through groove communicates with the inner cavity of the upper vent housing 30 and the vent hole 111 of the upper housing 11.

[0028] A frame-type sealing ring (made of high-temperature resistant material, such as mica) is sandwiched between the bottom edge of the bottom plate of the lower housing 12 and the top edge of the top plate of the bottom air intake housing 20. The bottom edge of the lower housing 12 and the top edge of the bottom air intake housing 20 are fixedly connected by bolts. A central through groove is formed in the middle of the top plate of the bottom air intake housing 20. The central through groove communicates with the inner cavity of the bottom air intake housing 20 and the vent hole 111 of the lower housing 12.

[0029] Furthermore, a main air outlet connector 31 is connected to one side plate of the upper air outlet housing 30, and the main air outlet connector 31 communicates with the inner cavity of the upper air outlet housing 30. A main air inlet connector 21 is connected to one side plate of the bottom air inlet housing 20, and the main air inlet connector 21 communicates with the inner cavity of the bottom air inlet housing 20.

[0030] Furthermore, a cooling gas outlet pipe 32 is connected to the center of the bottom surface of the main gas outlet connection pipe 31.

[0031] Furthermore, the bottom cavity of the bottom air intake housing 20 has a triangular cross-section, and the distance between the upper parts of the two inclined inner walls is less than the distance between the lower parts of the two inclined inner walls. The bottom plate of the bottom air intake housing 20 is connected to a downwardly extending lower cylindrical body 22, which communicates with the inner cavity of the bottom air intake housing 20. The bottom end of the lower cylindrical body 22 is formed with a lower conical discharge cylinder 221, and the bottom end of the lower conical discharge cylinder 221 is connected to a liquid outlet connecting pipe 23. An oil outlet pipe 24 is connected to the middle side plate of the lower cylindrical body 22.

[0032] Furthermore, a level gauge 25 (a conventional structure, not described in detail here) is installed at the top of the lower cylindrical body 22 and the liquid outlet connecting pipe 23. The upper connecting pipe of the level gauge 25 is fixed to the outer wall of the top of the lower cylindrical body 22 and communicates with a side through hole formed on the outer wall of the top of the lower cylindrical body 22. The lower connecting pipe of the level gauge 25 is fixed to the outer wall of the top of the liquid outlet connecting pipe 23 and communicates with a side through hole on the side wall of the top of the liquid outlet connecting pipe 23.

[0033] Furthermore, a liquid level sensor 26 is fixed on the outer wall of the side plate of the lower cylindrical body 22 corresponding to the oil outlet pipe 24, and the sensing end of the liquid level sensor 26 extends into the lower cylindrical body 22. The horizontal position of the sensing end of the liquid level sensor 26 is slightly lower than the horizontal plane where the central axis of the oil outlet pipe 24 is located, generally about 10mm lower.

[0034] Furthermore, a first solenoid valve is installed in the middle of both the oil outlet pipe 24 and the liquid outlet connection pipe 23.

[0035] In this embodiment, all electrical devices are electrically connected to the control host via electrical connection lines, and their operation is controlled by the control host.

[0036] In this embodiment, the inlet end of the main inlet pipe 21 is connected to the outlet end of the furnace body, and the outlet end of the main outlet pipe 31 is connected to the return end of the furnace body. The outlet end of the cooling gas distribution pipe 32 can be connected to a control valve, and the other end of the control valve is connected to a gas storage tank. The gas storage tank is under negative pressure. In this way, when there is too much gas in the furnace body and this embodiment, and the pressure increases, the control valve opens, and some of the cooled gas will be discharged from the outlet end of the cooling gas distribution pipe 32 and squeezed into the gas storage tank, thereby reducing the pressure on the furnace body and the components of this embodiment.

[0037] In this embodiment, the first heat exchange outlet water connection pipe 112 is connected to the water return pipe, and the first heat exchange inlet water connection pipe 121 is connected to the cooling water outlet pipe. The cooling water outlet pipe and the water return pipe are connected to the water-cooled chiller unit (which is a conventional structure and can be purchased directly, so it will not be described in detail here). The total cross-sectional area of ​​the inner flow cavity of all inner pipe bodies 14 is greater than or equal to the cross-sectional area of ​​the inner flow cavity of the main air outlet connection pipe head 31 or the main air inlet connection pipe head 21. The cross-sectional areas of the inner flow cavity of the main air outlet connection pipe head 31 and the main air inlet connection pipe head 21 are equal.

[0038] The hot gas from the furnace enters through the main air inlet connection pipe 21, reaches the bottom air inlet shell 20, and then enters all the inner tubes 14. The cooling water enters the lower shell 12 through the first heat exchange water inlet connection pipe 121, and then enters the outer tube 13. This allows the gas in the inner tube 14 and the water in the outer tube 13 to exchange heat, thereby cooling the gas. The cooled gas then enters the upper air outlet shell 30, and then exits through the main air outlet connection pipe 31 before entering the furnace body.

[0039] The water after heat exchange enters the upper shell 11 and then flows out from the first heat exchange outlet water connection pipe 112;

[0040] After cooling, some water droplets or oil will form in the gas, which will fall down the inner tube 14 and enter the lower cylindrical body 22 from the bottom air inlet shell 20. The liquid level in the lower cylindrical body 22 can be viewed through the level gauge 25. When the liquid exceeds the sensing end of the level sensor 26 (in this embodiment, the level sensor 26 is a photoelectric level sensor, which uses the principle of reflection and refraction of light at the interface of two different media to achieve sensing), the level sensor 26 senses the liquid. When it senses the liquid, the control host receives the signal transmitted by the level sensor 26 and processes it. Then, it opens the first solenoid valve at the oil outlet pipe 24 until the level sensor 26 is no longer in use. When liquid is detected, the first solenoid valve at the oil outlet pipe 24 closes. Then, the control unit controls the first solenoid valve at the liquid outlet connection pipe 23 to open, allowing water to flow out from the liquid outlet connection pipe 23. This usually lasts for about 60 seconds. Alternatively, the first solenoid valve at the liquid outlet connection pipe 23 can be manually closed based on the decrease in the liquid level gauge 25. The oil and some water above the sensing end of the liquid level sensor 26 can be discharged from the oil outlet pipe 24 (usually oil, occasionally some water, but this does not affect the discharge); the remaining water is discharged from the liquid outlet connection pipe 23 (occasionally a small amount of oil may be mixed in the liquid outlet connection pipe 23, but this does not affect the discharge).

[0041] The liquid discharged from its liquid outlet connection pipe 23 and oil outlet pipe 24 can be further processed and reused.

[0042] In this embodiment, the water and oil generated during cooling can be automatically discharged in real time, reducing accumulation, ensuring the normal operation of the equipment, and achieving good results.
