Abstract
The invention discloses a coal gas dust removal system for low-moisture coal coking, which comprises a coal gas washing tower connected with a primary cooler, and the coal gas washing tower is provided with a first nozzle for spraying a washing liquid to coal gas fed into the dust removal system. The coal gas dust removal system for low-moisture coal coking disclosed by the invention reduces the amount of dust entrained in coal gas by way of circulating washing, thereby reducing the influence on a subsequent coal gas purification system as far as possible.
Description
Technical field
The invention belongs to technical field of coal chemical industry, specifically, the present invention relates to a kind of gas dust removal system of low moisture coal coking.
Background technology
Conventional gas cleaning system can normally be run when the moisture of coke oven as-fired coal is about 10%, but after coal damping project comes into operation, when the moisture of coke oven as-fired coal drops to below 8%, after running for some time, gas cleaning system reflects that in system, coal dust carries obvious increase secretly.Gassy system shows that primary cooler resistance increases cleaning increased frequency, and after primary cooler, gas line coal dust etc. increase, and thionizer and Ammonic washing tower resistance increase, the phenomenons such as gas quality index variation.The problems referred to above worsen further with the lower general who has surrendered of as-fired coal moisture.
Summary of the invention
The invention provides a kind of gas dust removal system of low moisture coal coking, object reduces the entrainment of dust in coal gas, reduces the impact on follow-up gas cleaning system.
To achieve these goals, the technical scheme that the present invention takes is: a kind of gas dust removal system of low moisture coal coking, comprises the gas wash tower be connected with primary cooler, and gas wash tower is provided with the first shower nozzle for spraying washings to the coal gas entering inside.

Described gas wash tower has the inlet mouth be connected with gas-liquid separator and the air outlet be connected with described primary cooler, and air outlet is positioned at above inlet mouth.
Described first shower nozzle is positioned at the below of the air outlet of described gas wash tower.
Described gas wash tower has water outlet, and water outlet is positioned at below described first shower nozzle, and is connected with cleaning circulation pump and strainer between water outlet and the first shower nozzle.
The water outlet of described gas wash tower is positioned at the below of inlet mouth, the water-in of described cleaning circulation pump is connected with the water outlet of gas wash tower, the water outlet of cleaning circulation pump is connected with the water-in of described strainer, and the water outlet of strainer is connected with described first shower nozzle.
The sewage draining exit of described strainer is connected with mechanize tar ammonia clarifying tank.
The water outlet of described cleaning circulation pump is connected with suction gas line by pipeline.
Be provided with the second shower nozzle in described gas wash tower, the second shower nozzle is between described first shower nozzle and described inlet mouth.
The gas dust removal system of low moisture coal coking of the present invention, by by the mode of circulation cleaning to reduce the entrainment of dust in coal gas, reduce the impact on follow-up gas cleaning system as much as possible.
Accompanying drawing explanation
This specification sheets comprises the following drawings, shown content respectively:
Fig. 1 is the structural representation of the gas dust removal system of low moisture coal coking of the present invention;
Be labeled as in figure:
