Description

Technical Field

[0001] The invention relates to the technical field of hazardous waste disposal, and in particular to a sealing material distribution device and method for a high-temperature melting furnace. Background Art

[0002] With the rapid development of the environmental protection industry, high-temperature melting furnaces are also widely used in the hazardous waste disposal industry, mainly for the disposal of hazardous wastes such as industrial waste salt and garbage fly ash. As a device for melting solid wastes, hazardous wastes, etc. under high temperature conditions, the main purpose of the high-temperature melting furnace is to decompose and melt the wastes by high-temperature heating, so as to achieve harmless treatment and resource utilization. High-temperature melting treatment of hazardous wastes usually includes pyrolysis and melting treatment. The pyrolysis temperature is generally between 300℃ and 550℃. This process can remove most of the organic matter in the wastes; the temperature range during melting treatment is usually above 1000℃. This process melts the wastes and further removes the residual organic matter in depth, but it can be adjusted according to the actual waste treatment situation. When using a high-temperature melting furnace to dispose of hazardous wastes, the hazardous wastes contain a large amount of organic matter. After high-temperature treatment, synthesis gas (CO and H2) will be produced. Synthesis gas leakage poses a safety risk, and negative pressure operation is adopted in the high-temperature melting furnace. If the amount of air entering the furnace is large, it may also cause an explosion risk. Therefore, the requirements for its sealing performance have been greatly improved, and the traditional feeding device cannot meet this demand, so it is necessary to invent a high-temperature melting furnace feeding device with high sealing performance. In addition, if the material distribution is uneven, it is easy to cause local area burn-through, which will increase the temperature of the local gas phase space of the high-temperature melting furnace, increase the heat dissipation and increase the energy consumption.

The telescopic structure 3 passes through the elastic sealing member 51 and the mounting plate 52, and is fastened to the elastic sealing member 51 through the mounting sleeve 53. An opening is provided in the middle of the mounting plate 52 to meet the space for the telescopic structure 3 to move up and down. The elastic sealing structure 5 in this embodiment can save material costs, and if the elastic sealing member 51 is worn out after a period of use, it is easy to replace.

[0041] In other embodiments, the elastic sealing structure 5 may be an integral elastic structure fixedly connected to the material drop bin 2 , or the elastic sealing member 51 may pass through the middle of the mounting plate 52 .

[0042] The elastic sealing member 51 is made of flexible material, preferably an aluminum folding plate or a high temperature resistant skin, which is more durable and helps to reduce costs.

[0043] The other side of the blanking bin 2 is connected to the high-temperature melting furnace 8. The furnace wall of the high-temperature melting furnace 8 has embedded steel plates and studs. The blanking bin 2 is connected to the embedded steel plates in the furnace wall through the mounting flange 10 using embedded studs for easy disassembly. Preferably, a sealing gasket is provided on the contact surface between the mounting flange 10 and the embedded studs to improve the sealing effect.

[0045] In this embodiment, the telescopic structure 3 includes a cylinder outer sleeve 31 and a cylinder inner rod 32. One end of the cylinder outer sleeve 31 is installed above the liftable support structure 4, and the other end passes through the openings on the elastic seal 51 and the mounting plate 52, and is fastened to the elastic seal 51 through the mounting sleeve 53.

[0049] The telescopic structure 3 and the liftable support platform 4 in this embodiment are driven by a hydraulic pump station 11.

In other embodiments, electric or pneumatic driving methods can also be used, and the telescopic structure 3 can select an electric telescopic rod or a pneumatic telescopic rod.

By adopting the solution provided in the embodiment of the present invention, energy consumption can be greatly reduced. On the one hand, high sealing helps to prevent the heat loss caused by the overflow of hot flue gas in the furnace. On the other hand, the use of a push plate for material distribution helps to improve the uniformity of the material distribution, prevents the increase in the temperature of the local gas phase space in the high-temperature melting furnace caused by local area burn-through, and then reduces the heat dissipation, thereby achieving the purpose of reducing energy consumption. In the technical solution in the embodiment of the present invention, the push plate intermittently enters the high-temperature melting furnace, which greatly reduces the time the push plate is in the high-temperature melting furnace, and can effectively reduce the risk of high-temperature ablation and corrosion, thereby increasing the life of the material distribution device and reducing production costs.

[0073] In another specific embodiment, the support is adjusted to move the telescopic structure in a horizontal direction perpendicular to the telescopic direction, thereby driving the push plate to move in a horizontal direction perpendicular to the telescopic direction. For details, please refer to the specific high-temperature melting furnace sealing and distributing device in Example 4, which will not be described in detail here.

[0074] By adopting the solution provided in the embodiment of the present invention, when treating hazardous waste, the demand for high sealing can be met, the leakage of synthetic gases such as carbon monoxide can be prevented, and a large amount of external air can be prevented from entering the furnace to cause explosion risks, thereby ensuring the safe and stable operation of the high-temperature melting furnace. By adopting the solution provided in the embodiment of the present invention, energy consumption can be greatly reduced. On the one hand, high sealing helps to prevent the hot flue gas in the furnace from overflowing and losing heat. On the other hand, using a push plate for distribution helps to improve the uniformity of distribution, prevent the increase in the temperature of the local gas phase space in the high-temperature melting furnace caused by burning through in local areas, and then reduce the heat dissipation, thereby achieving the purpose of reducing energy consumption. In the technical solution in the embodiment of the present invention, the push plate intermittently enters the high-temperature melting furnace, which greatly reduces the time that the push plate is in the high-temperature melting furnace, and can effectively reduce the risk of high-temperature ablation and corrosion, thereby increasing the life of the distribution device and reducing production costs.
