Smoke Control Method of Tamping Coke High Pressure Ammonia Water Pump

Abstract

The invention relates to a tamping coke high pressure ammonia pump smoking control method. The method comprises the following steps: 1) when coal charging is carried out, pressure of high-pressure ammoniacal liquor is controlled to 2.2 MPa through a frequency converter; 2) when a coal-holding base plate moves forwardly for 20 s, the pressure of the high pressure ammoniacal liquor is increased to 3.1 MPa, production amount of raw coal gas is increased at the moment; 3) when the coal-holding base plate moves forwardly for 50 s, the pressure of the high pressure ammoniacal liquor is increased to 3.3 MPa, the production amount of raw coal gas is increased further at the moment; the production amount of the raw coal gas can reach the maximum amount at 50 s to 80 s; 4) when the coal-holding base plate moves forwardly for 88 s, the pressure of the high pressure ammoniacal liquor can reach 1.9 MPa, and 5) when the coal-holding base plate moves forwardly for 250 s, the pressure of the high pressure ammoniacal liquor is increased to 2.2 MPa. The method has advantages of simple process, high automation degree and good smoking control effect.

Description

technical field [0001] The invention relates to a smoke control method, in particular to a smoke control method for a tamped coke high-pressure ammonia water pump. Background technique [0002] It is difficult to control the smoke from coal charging in tamping coke ovens, and the environmental factors are prominent. It is tried to control the smoke from coal charging by increasing the pressure of high-pressure ammonia water, but the hidden dangers are serious leakage in the furnace body, and the smoke from the chimney can be prolonged for a long time. Without effective control, hot repair personnel are often in a rush repair state, and the labor intensity of personnel is relatively high. Contents of the invention [0003] In order to overcome the disadvantages of the prior art, the invention provides a smoke control method of a tamping coke high-pressure ammonia water pump. The method is simple, the degree of automation is high, and the smoke control effect is good. [0...
