Problems solved by technology

When burning, it uses hundreds to thousands of cubic meters of air per hour, consumes several tons to tens of tons of steam, and the temperature is still 120-500 degrees after heat energy recovery (waste furnace) and cooling. Environmental pollution is serious, which also causes waste of heat energy

Abstract

The invention relates to a pyrolysis furnace decoking gasification and purification as well as heat energy and material recovery device, comprising a tank body. The tank body is internally provided with a heat absorbing pipe, a water inlet pipe and a water outlet pipe, wherein, the water inlet pipe and the water outlet pipe are communicated with the heat absorbing pipe; the tank body is provided with an air inlet pipe and an exhaust pipe which are communicated with the inner chamber of the tank body; and the bottom of the tank body is provided with a solid / liquid material outlet. By adopting the device provided by the invention, the steam, coke powder, air and water in the waste gas from a pyrolysis furnace are separated, thus realizing 'four-phase separation'; the heat energy and the water resource in the waste gas are recovered; the emission is reduced; and the pollution on the environment is reduced. In the actual production, the device can directly replace a coke cleaning pot to operate.

Description

technical field [0001] The invention relates to a cracking furnace burnt steam purification and heat energy and material recovery equipment, which is mainly used for the recovery and utilization of heat energy and other energy sources of the waste steam of the cracking furnace. Background technique [0002] Cracking furnace is an important process equipment for ethylene production. At present, ethylene cracking furnaces at home and abroad still use burnt tanks, and its structural performance is empty tank to empty discharge. The cracking furnace is generally shut down once every 35-50 days, and a 24-hour cracking furnace burns coke and soot is blown. When burning, it uses hundreds to thousands of cubic meters of air per hour, consumes several tons to tens of tons of steam, and the temperature is still 120-500 degrees after heat energy recovery (waste furnace) and cooling. Environmental pollution is serious, also caused the waste of heat energy. Contents of the invention ...
