Method for detecting coke in coke tank

Abstract

The invention provides a method for detecting whether a coke tank has coke or not. The method comprises the following steps: a) uniformly mounting a plurality of charge level indicators along the circumferential direction of the top of a dry quenching furnace, and carrying out detecting by using the charge level indicators after a dry quenching crane fills the dry quenching furnace with red coke so as to obtain the values of coke levels in the dry quenching furnace, wherein the height of coke in the dry quenching furnace rises by 450 to 500 mm after one filling operation, and an alarm signal is given out if a coke level in the dry quenching furnace rises by less than 300 mm after filling of the red coke; and b) when the crane rises to the top of a head mast, allowing the crane to stop at the position for a plurality of seconds, weighing total weight by using a crane weighing system, recording the total weight, then allowing the crane to stop for a plurality of seconds again after the crane charges red coke into a red coke tank and returns to the top of the head mast, then carrying out weighing, and subtracting the weighing data of the crane before charging of red coke from the weighing data of the crane after charging of red coke so as to obtain the amount of charged red coke, wherein if the amount of charged red coke is greater than a set value, it is indicated that all the red coke is charged, or if the amount of charged red coke is less than a set value, it is indicated that residual red coke exists, and an alarm signal is give out to inform operation staff of carrying out confirmation.

Description

technical field [0001] The invention relates to coke oven technology, in particular to a method for detecting no coke in a coke tank. Background technique [0002] The coke pushing operation of the coke oven is completed by four major locomotives: coke pushing car, coke guiding car, coal loading car and coke transporting car. The coke pusher pushes the coke in the carbonization chamber into the empty coke tank, and the coke truck transports the full coke tank to the CDQ system. After the coke is loaded into the CDQ oven, the empty coke tank returns to the coke truck to continue the next furnace No. coke receiving operation. The design volume of the coke tank can only accommodate one furnace of coke. After each coke pushing operation, it must be confirmed that the coke in the coke tank has been loaded into the CDQ oven before re-connecting the coke. Otherwise, the coke at about 1050°C will overflow the coke tank. Burnt coke truck and other equipment. During the coke pushin...

AI Technical Summary

Problems solved by technology

Once the above problems occur and the driver fails to find out in time, coke overflow coke tank accidents will occur, resulting in major equipment losses and even personal injuries

This method is easy to do at night, but it is more difficult to judge during the day
