Flue gas adsorbing and purifying device for coke oven

Abstract

The invention discloses a flue gas adsorbing and purifying device for a coke oven. The flue gas adsorbing and purifying device comprises an air channel and independent filtering units, wherein the air channel is formed in a barrel; the two ends of the air channel are provided with an air inlet and an air outlet respectively; and more than two independent filtering units are laminated in the barrel, and are used for correspondingly partitioning the air channel into parallel channels. Compared with the prior art, the invention has the beneficial effects that: the laminated independent filtering units form a plurality of filtering channels for treating waste gas respectively, so that the filtering area is increased effectively, the waste treating efficiency is increased, higher filtering efficiency and larger waste gas treating amount are realized under the condition of the same floor area, setting of the device can be reduced, and the purchasing cost and running cost are objectively reduced.

Description

technical field [0001] The invention relates to an adsorption and purification device for coke oven flue gas. Background technique [0002] The combustible gas components in the flue gas generated during tamping coke oven charging are much larger than those of conventional coke oven charging, and also contain more tar (about 30g / m 3 ) and water vapor. The dew point temperature of the flue gas is relatively high, and the dust is mostly lighter carbon black fly ash produced by incomplete combustion, which increases the difficulty of flue gas purification for tamping coke oven coal charging. [0003] The current flue gas adsorption and purification device is a flue gas adsorption and purification device that uses a filter material layer to separate dust and tar in the flue gas from the gas. The structure of the current flue gas adsorption purification device is as follows: figure 1 As shown, the main body shell 81 is a vertical cylindrical cylinder, and the main body shell 8...

AI Technical Summary

Problems solved by technology

[0005] The effective adsorption area of ​​the current flue gas adsorption and purification device is only the annular surface area of ​​the filter material layer, which is relatively small, resulting in low working efficiency of the flue gas adsorption and purification device for waste gas treatment, requiring multiple units to be used in parallel, resulting in increased production costs (including purchase cost and operating cost of water, electricity, etc.), occupying a large area, which is not conducive to layout

In addition, the effective space inside the equipment is small, it is inconvenient to clean the inside, and it is inconvenient to replace the coke block, which greatly reduces the work efficiency and increases the maintenance cost of the equipment
