Description

Technical Field

[0001] The utility model relates to a water shortage and dry burning prevention system for cooling a cooling water jacket of calcined coke, belonging to the technical field of pre-baked anode calcined coke production. Background Art

[0002] With the rapid development of modern aluminum industry technology, in my country's electrolytic aluminum production, as the production scale expands, the production capacity of the corresponding calcining furnaces is also increasing. The calcining furnace type is also developing towards larger furnaces and multiple groups. The cooling water jackets of calcined coke are also getting larger. The safe operation of the cooling water jacket is also an important factor in the safe production of the calcining furnace. Therefore, more stringent requirements are put forward for the safe operation of the cooling water jacket.

[0003] Current technology is incomplete and suffers from the following drawbacks: Conventional cooling jacket water circulation systems fail to incorporate water replenishment in response to a water shortage, making it impossible to ensure timely replenishment of the cooling jacket when it is short of water, and to achieve automated, continuous operation. Consequently, some cooling jackets experience water shortages for various reasons, which go undetected and lead to prolonged, high-temperature, dry-burning damage.

[0004] In order to solve one of the above problems, a system for preventing dry burning of the cooling water jacket of calcined coke is urgently needed. Utility Model Content

[0005] In view of the above deficiencies in the prior art, the technical problem to be solved by the present invention is: how to realize the automatic and continuous operation of water replenishment of the cooling water jacket of the calcining furnace, and to provide a water shortage and dry burning prevention system for cooling the cooling water jacket of calcined coke.

A water outlet is installed at the middle and upper part of the cooling water jacket, and the water outlet is communicated with the main return water pipe through the water jacket outlet pipe. The utility model is characterized in that it also comprises a water supply main pipeline, a high-level water tank located above the cooling water jacket, and an automatic water supply pipeline communicated with the high-level water tank.

A water supply port is provided at the top of the cooling water jacket, and the water supply port and the water supply main pipeline are communicated through pipe three.

[0007] When the upper portion of the water jacket is short of water, water from the high-level water tank automatically flows into the water jacket due to the high head difference, achieving continuous and automatic water replenishment of the water jacket. This effectively prevents damage to the cooling water jacket due to dry burning due to water shortage, extends the service life of the cooling water jacket, reduces the manpower and material resources consumed in water jacket replacement, saves production and operation costs, reduces manual labor, ensures normal and stable operation of the water jacket in a high-temperature operating environment, reduces production and operation costs, and improves the production efficiency and product quality of calcined coke.

[0009] Preferably, the detection device includes a radar level gauge mounted above the high-level water tank and a magnetic flap level gauge mounted on the side wall of the high-level water tank. The radar level gauge and magnetic flap level gauge are electrically connected to the controller via corresponding signal lines, and also includes an audible and visual alarm connected to the controller. The high-level water tank liquid level signal collected by the level gauge is sent to the controller, which then controls the opening and closing of the solenoid valve to supply water to the water tank, so that the high-level water tank always maintains a certain liquid level.

[0010] Preferably, the upper portion of the high-level water tank is connected to an overflow pipe, and the other end of the overflow pipe is connected to the water jacket outlet pipe or the main return pipe.

A water supply port is provided at the top of the cooling water jacket 1, and the water supply port is connected to the water supply main pipeline 7 through pipe 3.

[0022] When the upper portion of the water jacket is short of water, water from the high-level water tank automatically flows into the water jacket due to the high head difference, achieving continuous and automatic water replenishment of the water jacket. This effectively prevents damage to the cooling water jacket due to dry burning due to water shortage, extends the service life of the cooling water jacket, reduces the manpower and material resources consumed in water jacket replacement, saves production and operation costs, reduces manual labor, ensures normal and stable operation of the water jacket in a high-temperature operating environment, reduces production and operation costs, and improves the production efficiency and product quality of calcined coke.

[0023] Example 2, as Figure 1-2 As shown, a water shortage and dry burning prevention system for cooling a cooling water jacket for cooling calcined coke comprises a cooling water jacket 1, a water jacket inlet pipe 2, a water jacket outlet pipe 3 and a main return water pipe 4. A water inlet is provided at the bottom of the cooling water jacket 1, and the water inlet is connected to the water jacket inlet pipe 2 through pipe 1. A water outlet is installed at the upper middle part of the cooling water jacket 1, and the water outlet is connected to the main return water pipe 4 through the water jacket outlet pipe 3. It also comprises a water supply main pipeline 7, a high-level water tank 5 above the cooling water jacket 1 and an automatic water supply pipeline connected to the high-level water tank 5. The drain outlet at the bottom of the high-level water tank 5 is connected to a water outlet main pipeline, and the water supply main pipeline 7 is connected to the water outlet main pipeline through pipe 2. A water supply port is provided at the top of the cooling water jacket 1, and the water supply port is connected to the water supply main pipeline 7 through pipe 3.

[0024] Furthermore, it also includes a detection device for detecting the water level in the high-level water tank 5. A water supply solenoid valve 6 is installed on the automatic water replenishment pipeline.

[0025] Furthermore, the detection device includes a radar level meter 10 installed above the high-level water tank 5 and a magnetic flap level meter 11 installed on the side wall of the high-level water tank 5. The radar level meter 10 and the magnetic flap level meter 11 are electrically connected to the controller 12 through corresponding signal lines, respectively, and also include an audible and visual alarm 13 connected to the controller 12.

[0026] The liquid level signal of the high-level water tank collected by the liquid level meter is sent to the controller, and the controller then controls the opening and closing of the solenoid valve to supply water to the water tank, so that the high-level water tank always maintains a certain liquid level.

When the upper part of the cooling water jacket 1 is short of water, the water in the high-level water tank 5 is automatically injected into the cooling water jacket through the water supply main pipe and the water supply branch pipe under the action of the high head difference. At the same time, the gas generated in the cooling water jacket rises to the high-level water tank 5 through the cooling water jacket, the water supply branch pipe 8, and the water supply main pipe 7 to be released, which not only plays the role of water supply, but also plays the role of releasing gas to prevent gas blockage.

Meanwhile, the computer program involved is a simple program that can be easily implemented by those skilled in the art using an existing computer program development platform and well-known programming methods.
