Roasting furnace device

Abstract

The invention provides a roasting furnace device. The roasting furnace device comprises a flue, a steam generator, a steam-water separator, smoke exhaust cylinders, a control box and variable-frequency fans. The flue communicates with a kiln through a smoke inlet. The steam generator is installed inside the kiln in an integrated mode and communicates with the steam-water separator. The steam-water separator is arranged outside the flue. The smoke exhaust cylinders are arranged at the two ends of the flue. The control box is electrically connected with the steam-water separator and the smoke exhaust cylinders. The variable-frequency fans are arranged on the smoke exhaust cylinders. According to the roasting furnace device, due to the arrangement of the steam generator and the steam-water separator, heat in flue gas inside the kiln is fully used, heat loss of exhausted smoke is reduced, the temperature of the exhausted smoke is decreased, pollution is reduced, and meanwhile cycle use can be achieved; and due to the arrangement of the control box as well as temperature, pressure and flow instruments, the intelligent control degree is improved, automatic water supplement is achieved, the flue gas temperature curve and the water line are monitored, water level alarm and interlocking are achieved, and use is more convenient.

Description

technical field

[0001] The invention belongs to the technical field of roasting furnaces, and in particular relates to a roasting furnace device. Background technique

[0002] The roasting process is the most important energy-consuming process in the production process of carbon products, and the energy consumption of the roasting process directly affects the production cost of pre-baked anodes. On the other hand, the more energy consumption is added, the coal tar pitch smoke will not be fully burned in the flue, and it can only be discharged with the roasting flue gas, which wastes energy and pollutes the environment. Therefore, the development of new energy-saving and low-emission roasting furnace technology is of great significance to reduce the energy consumption of pre-baked anodes and reduce the smoke pollution of roasting furnaces. In the prior art, the flue settings are generally integrated. Filtration and removal of impurities means external discharge, which has th...
