Embodiment Construction

[0015] Along with the use of new type integrated start-up burner, original ignition burner stops using, and this has just emptied an effective channel for gasification furnace, and the present invention just appears on this basis.

[0016] Such as figure 1 As shown, the present invention includes a furnace monitoring mechanism 2 and an electronic ignition detection device. The monitoring mechanism is similar in shape to the ignition burner and extends into the furnace 1 . The present invention adopts a multi-tube structure, the outermost jacket is the cooling water inlet channel 9, and the inner jacket is the cooling water outlet channel 10; cooling water flows continuously during operation, so that the outer surface of the shell 8 is always kept in a safe Within the temperature range, the adaptability of the monitoring mechanism in the high temperature and high pressure environment is effectively improved; the head of the shell is designed with double-layer transparent glass,...

Abstract

The invention relates to a gasifier monitoring device. The gasifier monitoring device comprises a combustion chamber monitoring mechanism and an electronic ignition monitoring device. The monitoring mechanism comprises a columnar hollow shell body and transparent glass which is used for sealing the front end of the shell body. A monitoring device which is placed behind the transparent glass and a cable channel which leads to the back end of the shell body are arranged inside the shell body. The shell body comprises a cooling water inlet channel, a cooling water outlet channel and a nitrogen gas channel in sequence from outside to inside. The cooling water inlet channel, the cooling water outlet channel and the nitrogen gas channel are arranged in a concentric mode. The technical problems that an existing monitoring device is not high in accuracy and misjudgment easily occurs are solved. Working conditions of a burner nozzle head burning torch is indirectly monitored through the monitoring over system current, dangerous factors brought by high temperature and high pressure environments are avoided ingeniously, and complexity level of actual operation is greatly reduced.

Description

technical field [0001] The invention relates to a gasification furnace monitoring device. Background technique [0002] The pressurized coal gasification process has always enjoyed a high reputation in the field of coal chemical industry for its many advantages. Due to the initial design of the gasification unit, the ignition start-up system lacks monitoring facilities. At present, the accuracy of the ultraviolet flame monitoring equipment used has not been high, which is mainly due to the limitation of the position of the gasifier. There are also many gasifiers that have installed camera equipment, and rely on the camera equipment to observe the situation in the furnace when driving, but The accuracy of these methods is not high enough, and there are many human factors, which are prone to misjudgment and lead to unplanned parking and multiple ignitions, resulting in significant economic losses. Contents of the invention [0003] In order to solve the technical problem t...
