Embodiment Construction

[0019] Such as figure 1 , figure 2 , image 3 As shown, a coke oven gas naphthalene removal device includes a high-gravity rotating packed bed 2, and the high-gravity rotating packed bed has a total of four connection ports: a liquid inlet 31, a liquid discharge port 32, an air inlet 33 and an exhaust port 34 , which are basically consistent with existing technologies. The liquid outlet and the liquid inlet of the high-gravity rotating packed bed 2 are respectively connected to the same naphthalene-removing liquid tank 4 through pipelines, and a power pump 41 is connected to the pipeline between the high-gravity rotating packed bed and the naphthalene-removing liquid tank to realize The flow of denaphthalene solution. The naphthalene removal liquid tank 4 is connected to the waste liquid tank 5 through the naphthalene removal liquid extraction pump 51, and the naphthalene removal liquid tank 4 is connected to the new naphthalene removal liquid tank 6 through the naphthalen...

Abstract

The invention relates to a coke oven gas naphthalene-removing device and a coke oven gas naphthalene-removing method which are particularly applicable to industrial production of coke oven gas naphthalene removal. A set of naphthalene removal system and process method are designed by effectively introducing a supergravity rotating packed bed. The core of the device is a cross flow rotating packed bed, gas and liquid are contacted in a cross flow way, the phenomenon of flooding due to overlarge air flow is not easy to occur, a large space does not need to be reserved between a liquid spray pipe and a filler layer, and the radial dimension of the filler layer is reduced, thereby reducing the rotating energy consumption of a rotor and being more energy-saving.

Description

technical field [0001] The invention relates to a device and method for removing naphthalene from coke oven gas, which is suitable for deep removal of naphthalene from industrialized coke oven gas. Background technique [0002] Coke oven gas power generation is a way of comprehensive utilization of coke oven gas. It can not only achieve self-sufficiency in the production and consumption of high energy-consuming enterprises such as iron and steel and coking, but also provide abundant electricity to nearby residents, which greatly alleviates the The pressure on urban electricity consumption has important social significance. Naphthalene in coke oven gas is easy to crystallize, and it is easy to block power generation equipment, so coke oven gas should be denaphthalene before power generation. At present, the denaphthalene removal of domestic coke oven gas generally adopts the spraying and washing process of denaphthalene removal liquid, and multiple washing towers can be conn...
