Active coke flue gas purification device and cooling method

Abstract

The invention relates to an active coke flue gas purification device and a cooling method. The device comprise a flue gas purification bin, wherein a feeding port is formed in the upper end of the flue gas purification bin, a discharge port is formed in the lower end, a gas inlet flue is arranged at the lower part of one side, a gas outlet flue is arranged at the upper part of the other side, anda plurality of cooling walls are arranged in the flue gas purification bin and divide the flue gas purification bin into a plurality of flue gas purification chambers; the plurality of flue gas purification chambers are all communicated with the feeding port, the discharge port, the gas inlet flue and the gas outlet flue. According to the purification device, when temperature rise of a certain flue gas purification chamber is abnormal, only flue gas circulation of the flue gas purification chamber can be cut off, cut-off of flue gas flow of the whole device is avoided, and the utilization rateof the device and the purification efficiency of the flue gas are increased.

Description

technical field [0001] The invention relates to an active coke flue gas purification device, which belongs to the technical field of industrial tail gas purification. Background technique [0002] During the process of purifying flue gas, activated coke generates physical adsorption heat, chemical adsorption heat and chemical reaction heat. Due to the structural design of the purification device and the operation adjustment during the purification process, heat accumulation is generated locally in the device, resulting in a rise in temperature. When the ignition point of the active coke is reached, a fire accident will occur when the active coke contacts with oxygen, which will affect the production process and cause economic loss. The currently used activated coke flue gas purification device, when the temperature rises to cause a fire hazard, measures such as closing the flue gas inlet and outlet pipeline valves of the entire device, feeding nitrogen into the device, and ...

AI Technical Summary

Problems solved by technology

None of the above-mentioned patents has a dedicated device for cooling the active coke. When the temperature rise of the active coke in the tower is abnormal, that is, the temperature rises rapidly or the temperature rises to a certain level, the only way to cut off the flue gas flow in and out of the entire tower is to give Nitrogen is introduced into the entire tower to speed up the material circulation in the tower to cool down, which reduces the flue gas purification amount and purification effect, reduces the cooling speed, increases the consumption of active coke, and increases the risk of fire
