Abstract

The invention discloses a method for controlling the forward paper of a messy paper oven number of a coke oven, which belongs to the technical field of coke oven thermal engineering and sequentially comprises the following steps of installing a K-type thermocouple on a sampling hole at the root of a messy paper oven number ascending pipe, replacing a pore plate of a combustion chamber of the messy paper oven number with a pore plate required for prolonging coking time after the messy paper oven number is charged with coal, recording data of the K-type thermocouple at first time intervals, closing a gas adding and subtracting cock of the messy paper oven number after the data of the K-type thermocouple reach the first temperature, prolonging the coking time of the messy paper oven number by 1/4 of a normal oven number, opening the gas adding and subtracting cock after the coke pushing and charging operation of the messy paper oven number is finished, and repeating the steps S3-S5 until the forward paper is processed. The forward or backward throwing method is not needed to be judged, the forward paper time is 3-4 days, compared with the traditional forward method, the forward paper operation time and the misoperation hidden danger brought by the forward paper process are greatly shortened, and compared with the traditional backward throwing method, the forward paper operation time and the misoperation hidden danger brought by the forward paper process are shortened by half.

Description

Method for controlling order of messy-paper oven number of coke oven Technical Field The invention relates to the technical field of coke oven thermal technology, in particular to a method for controlling the order of a messy oven number of a coke oven. Background One or several oven numbers delaying the pushing of the coke are created for various reasons, which creates a so-called "mess". At this time, when planning, the 'return to the paper' should be gradually changed to be normal in a shorter time as much as possible. The method for recovering the normal state is as follows: (1) And (3) forward lifting, namely, forward lifting the messy furnace number by 1-2 furnaces when the furnace is discharged each time, so as to gradually reach the original position of the furnace in the sequence. This method does not lose the number of ovens, but is slow to adjust, typically requiring a month. (2) The furnace number is not discharged when the furnace is discharged, so that the furnace number is thrown backwards and gradually adjusted to the original position, thus the adjustment is quick, but the furnace number is lost. The original messy note number control method has the defects that: (1) The condition can be provided forward and the condition is not explained. (2) In the original mess number control method, the control of the temperature of the combustion chambers at the two sides of the mess number carbonization chamber is not described. (3) If the messy paper number is half coking time after being dragged by repairing the furnace wall, firstly, the forward paper time needs at least 33 days, and secondly, the backward paper time needs at least 7 days. The existence of the messy paper number needs to pay attention to the low-temperature number (forward precondition) and the high-temperature number (backward lost), more importantly, the messy paper number frequently breaks the wrong furnace door and breaks the wrong misoperation phenomenon of the ascending pipe cover in the actual coke pushing and coal charging process, and the quick paper is beneficial to avoiding the potential production hidden trouble. Disclosure of Invention The invention aims to provide a method for controlling the forward paper of a messy paper oven number of a coke oven, which is mainly applied to the current large-sized coke oven and solves the problems of long forward paper process time and high operation difficulty of the messy paper oven number. In order to achieve the above purpose, the present invention provides the following technical solutions: A method for controlling the order of a messy order of a coke oven number comprises the following steps in sequence: s1, installing a K-type thermocouple on a sampling hole at the root of a messy furnace number ascending pipe; s2, after the messy furnace number is charged with coal, replacing the pore plate of the furnace number combustion chamber with a pore plate required by prolonging coking time; s3, recording data of the K-type thermocouple once at intervals of first time; S4, after the data of the K-type thermocouple reach the first temperature, closing a gas adding and subtracting cock of the mess furnace number; S5, prolonging coking time of the messy furnace number by 1/4 of that of a normal furnace number; s6, after the coke pushing and loading operation of the messy paper furnace number is finished, opening a gas adding and subtracting cock, and repeating the steps S3-S5 until the paper is smooth. Preferably, the first temperature is 280 ℃. Preferably, the first time is 1 hour. Compared with the prior art, the invention has the beneficial effects that: The method does not need to judge whether the forward or backward dropping method is needed, the forward paper time is 3-4 days, compared with the traditional forward method, the time of forward paper operation and the misoperation hidden danger brought by the forward paper process are greatly shortened, compared with the traditional backward dropping method, the time is shortened by half, the standardized operation is realized for the forward paper in a data mode for the first time, and the uncontrollable factors brought by the original experience are overcome.
