Method for carrying out joint detection on states of riser and coal charging hole cover of coke oven

Abstract

The invention provides a method for carrying out joint detection on the states of a riser and a coal charging hole cover of a coke oven. The method comprises the following steps: installing a temperature detection device at a position where the riser and the coal charging hole cover can be scanned, wherein the position is far away from the riser and the coal charging hole cover; detecting to obtain the temperature of all the parts of the riser; controlling a coal charging process of the coke oven; monitoring the damage conditions of the riser and the coal charging hole cover of the coke oven.The method fully combines the characteristics of production of the coke oven, the operation characteristics of a coal charging car and an automatic detection technology, can be used for rapidly and effectively detecting the opening and closing of a cover of the riser, and realizes the reliable and safe interlocking with a coal charging operation; a detection and judgment unit is far away from a high temperature area; the method is a most direct and reliable detection technology for detecting the opening and closing states of the cover of the riser. After the method is adopted, the working state of a straight pipe section of the riser can be monitored in real time, so that problems can be found at the first time, and riser explosion and irreversible damage to an oven body of the coke oven are further avoided; therefore, the method is an important support technological means for coke oven safety production.

Description

technical field [0001] The invention belongs to coke oven automation technology, in particular to a combined detection method for the state of a coke oven riser and a coal charging hole cover. Background technique [0002] The rising pipe is the necessary channel for the export of high-temperature raw gas during the coking process of the coke oven. The cover of the rising pipe is closed during the coking process. The waste heat recovery riser with indirect heat exchange between the pipe section and water also has the traditional riser lined with refractory material. [0003] With the intensification of market competition and the increase of labor costs, the unmanned operation of coke oven coke pushing has become the main direction of the current coking industry. Among them, it is most difficult to realize unmanned coal loading vehicles. In addition, the coal loading operation is directly related to the state of the riser, and the automatic judgment of the state of the riser...

Problems solved by technology

[0005] In addition, the existing coal charging hole cover structure for coke ovens is a simple cover seat structure, which is composed of two parts: the coal charging hole cover and the coal charging hole seat. Since the coal charging hole cover has been working in a high temperature environment for a long time, it is easy to be damaged. After a period of time, it is easy to cause temperature and energy loss, and it is easy to cause the leakage of sulfur dioxide and other polluting gases, causing environmental pollution; in addition, it may also be accompanied by open flames emerging from the furnace, which is dangerous to the personal and health safety of workers.
