Embodiment Construction

[0023] The technical solutions of the present invention are further described below with reference to the accompanying drawings and embodiments.

[0024] please combine Figure 1 to Figure 3 As shown in the figure, a coke pit waste gas collection and purification system provided by the present invention is installed at the coke outlet 2 position of the coke pit 1, and includes a gas collecting hood 3, a gas collecting fan 4 and a coke adsorption tower 5. At the coke outlet 2 On the top, two gas collecting hoods 3 are added at the positions where coke powder and water vapor are relatively concentrated. The two gas collecting hoods 3 are connected with the gas collecting fan 4 through the connecting pipe 6, and the gas collecting fan 4 is connected with the coke adsorption tower 5 through the connecting pipe 7. Connected, more than 90% of the coke powder and water vapor at the position of the coke outlet 2 are pumped to the coke adsorption tower 5 through the gas collecting fan ...

Abstract

The invention discloses a coke pit exhaust gas collecting and purifying system which is arranged in a position of a coke outlet of a coke pit. The system comprises gas collecting hoods, a gas collecting fan and a coke adsorption tower. The gas collecting hoods are arranged at the coke outlet of the coke pit and are connected to the gas collecting fan through a connecting pipeline, and the gas collecting fan is connected to the coke adsorption tower through the connecting pipeline. A spray pipe is arranged at the bottom of the gas collecting hood, a plurality of spray ports for spraying condensate water are arranged on the spray pipe, and multiple layers of baffle plates are arranged in the gas collecting hood; the coke adsorption tower comprises a tower body, and packing, a mist capturingsystem and a spraying system arranged in the tower body, wherein the packing is located in a middle section of the tower body, the mist capturing layer is located above the packing, and the spraying system is located above the mist capturing layer. By additionally arranging two gas collecting hoods at the coke outlet of the coke pit, more than 90% of coke powder and water vapor are extracted to the coke adsorption tower through the gas collecting fan to be treated and discharged by reaching the standard.

Description

technical field [0001] The invention relates to a coking production process, in particular to a coking pit waste gas collection and purification system. Background technique [0002] In the coke pits of petrochemical delayed coking, coal tar pitch coking and needle coke processes, since the material (coke mass) in the coke pit is constantly changing, on the one hand, its origin is constantly coming down from the upper coking tower, and on the other hand, it is constantly changing. It was taken away by the upper traffic, so the upper part of the scorch pit can only be opened. Since the coke lumps come down from the inside of the coking tower, after the coking tower coking period is over, steam purging is used to drive out the mixed oil without coking, and at the same time achieve the purpose of cooling the coking tower, and then carry out water cooling, drainage, and coke removal. Industry. Therefore, the coke mass coming down from the coking tower contains a lot of water v...
