Double-chamber kiln oxygen-enriched blending method
The invention discloses a double-chamber kiln oxygen-enriched blending method. According to the method, a double-chamber kiln oxygen-enriched blending device is adopted to input oxygen into a kiln cylinder so as to control the oxygen content in the kiln cylinder; the oxygen-enriched blending device for the double-hearth kiln comprises an oxygen tank, an electric control valve, a pressure reducing valve, a pressure gauge, a safety valve, a check valve, an oxygen blending quick-switching valve, a flow meter and a blending mixing device which are sequentially arranged on an oxygen blending pipeline, when the oxygen content value required to be blended reaches a certain value, the control program is as follows: the oxygen pressure is reduced and controlled to be 50kpa-100kpa; when the oxygen conveying amount is low, the electric adjusting valve increases the oxygen conveying amount, and when the oxygen conveying amount is high, the electric adjusting valve decreases the oxygen conveying amount; when the gas quick-switching valve is closed, the oxygen blending quick-switching valve is quickly closed at the same time; and when the gas quick-switching valve is opened, the oxygen blending quick-switching valve is opened after 5-10 seconds. According to the invention, the problems of poor product quality and high consumption of the double-chamber kiln due to low calorific value of coal gas in the existing double-chamber kiln can be solved.
本发明公开一种双膛窑富氧掺配方法，它采用双膛窑富氧掺配装置向窑筒输入氧气从而控制窑筒内氧气含量；所述双膛窑富氧掺配装置包括依次设在氧气掺配管道上的氧气罐、电动调节阀、减压阀、压力表、安全阀、止回阀、氧气掺配快切阀、流量表和掺配混合装置；当需掺配含氧值达一定值时，控制程序为：氧气压力经过减压，控制在50kpa‑100kpa；偏低时，电动调节阀调大氧气输送量，偏高时，电动调节阀调小氧气输送量；当煤气快切阀关闭时，氧气掺配快切阀同时快速关闭；当煤气快切阀打开时，氧气掺配快切阀滞后5‑10秒打开。本发明可解决现有的双膛窑存在的因煤气热值偏低，导致双膛窑产品质量较差，各类消耗偏高的问题。
