Description

Technical Field

[0001] The utility model relates to a high-pressure spray system for dust removal on the furnace surface of an Acheson graphitization furnace. Background Art

[0002] The structure of the Qixun graphitization furnace is as follows: in a long furnace body constructed of refractory materials, carbon blanks and granular materials are loaded to form a conductive furnace core, and the furnace core is surrounded by heat-insulating materials. Conductive electrodes are set at the furnace heads at both ends and connected to the power supply to form an energized circuit. When the circuit is connected, the furnace core heats up due to the effect of resistance, so that the carbon blank is transformed into artificial graphite at a temperature of 2200-2300°C through high-temperature heat treatment;

[0003] The Acheson graphitization furnace will generate a large amount of dust during the production process. If the dust is not managed and discharged in an unorganized manner, it will not only fail to meet environmental protection requirements, but will also cause harm to the physical and mental health of employees.

[0004] Existing dust reduction equipment includes dust suppression cannons and dust suppression spray cannons, but the above dust reduction equipment cannot be used in the Acheson graphitization furnace and factory area. The specific problems are as follows: First, there are generally hoisting equipment at high altitudes in the graphitization furnace operating area. High-altitude spraying not only seriously affects the line of sight of the hoisting operation, but also long-term high-altitude spraying in the factory area can easily cause the equipment and lines to become damp, and the risks of falling objects and safety increase; secondly, the existing dust reduction equipment sprays a large amount of water mist to reduce dust and wet the ground at the same time, which has the effect of suppressing dust in the air and the road surface at the same time, but the ground in the graphitization furnace operating area is wetted, and there is a risk of leakage and slipperyness, which seriously affects production safety; in addition, 3. Existing dust reduction equipment often requires the use of vehicle towing, large fans and other equipment in conjunction, which further increases the noise in the factory area. The layout of vehicle travel passages in the factory area also reduces the efficiency of space utilization in the factory area. Utility Model Content

[0005] The utility model aims to provide a high-pressure spray system for dust removal on the furnace surface of an Acheson graphitization furnace, so as to solve the technical problem that the existing dust reduction equipment cannot be applied to the production plant of the Acheson graphitization furnace.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

The water source filtration system is connected to a water source. The water outlet of the water source filtration system is connected to the water inlet of the water tank through a pipeline. The water outlet of the water tank is connected to the water inlet of the micro-mist dust removal host. The water outlet of the micro-mist dust removal host is connected to several groups of spray components.

[0008] All the spray components are arranged in parallel, and each group of spray components includes a spray pipe. The micro-mist dust removal host is connected to the spray pipe through a water pipe, a control valve is installed on the water pipe, and a row of water mist nozzles are arranged on the spray pipe.

[0009] Furthermore, the water mist nozzle includes a reducer and a reducer, and an extension tube, the reducer and a reducer are connected to the spray pipe, an inner thread is installed on the reducer, a swivel joint is provided on the inner thread, a bushing is installed on the swivel joint, the extension tube is installed on the bushing, and a nozzle part is provided at the end of the extension tube.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows: the utility model is a two-fluid dust reduction system that combines compressed air and water and is developed to target the large dust in the Acheson graphitization furnace. It is a micron-level high-pressure spray system. The micro-mist dust removal host can carry multiple devices and work intermittently. The entire process is fully automated and does not require manual labor. The principle of this system is the atmospheric water mist cleaning method. Spray points are set in the control areas where dust and haze need to be reduced and combined with the Philippine mist dust reduction method to form a fully covered micron-level water particle curtain in the local area. The system uses a series of effective combinations such as automatic control to achieve professional dust reduction design for the graphitization furnace surface, ensuring that the high-pressure micro-mist covers all corners.
