Embodiment 1
[0050] Such as Figure 1-8 , a coke oven fire hole pressure automatic adjustment control system in this embodiment includes a pressure measuring device, a DCS system, an input module, an output module and a flue flap adjustment actuator, and the pressure measuring device includes a plurality of, respectively Correspondingly installed above the fire viewing hole of the coke oven vertical flue, and connected to the DCS system through the input module, and the DCS system is connected to the flue flap adjustment actuator through the output module. Specifically, the pressure measuring device includes a pressure measuring hole cover 1 and a micro pressure transmitter 2. The pressure measuring hole cover 1 is an iron casting integrally casted together by a fire hole cover 11 and a pressure introduction pipe 12. The micro pressure transmitter 2 is installed on the top of the pressure introduction pipe 12 . The micro pressure transmitter 2 enters the measured current signal into the s...
Embodiment 2
[0052] The main structure of the coke oven fire hole pressure automatic adjustment control system of this embodiment is basically the same as that of Embodiment 1, and the main difference is that: image 3 As shown, the fire viewing hole cover 11 is an inverted trapezoidal structure, and its top edge extends outwards for covering the fire viewing hole. The lower part forms an inverted trapezoid, and the inside is hollow. The pressure introduction pipe 12 is arranged at the central position of the fire hole cover 11, and the lower end of the pressure introduction pipe 12 protrudes from the lower edge (i.e. the bottom) of the fire hole cover 11 by 150-200mm, and its upper end protrudes from the upper edge of the fire hole cover 11. (i.e. the top) 30-50mm, and the gap formed between it and the inside of the fire hole cover 11 is poured with lightweight heat insulating mud 13 to reduce the surface temperature of the pressure measuring hole cover 1 and prevent the tiny pressure tran...
Embodiment 3
[0054] A coke oven fire hole pressure automatic adjustment control system of this embodiment, its main structure is basically the same as that of embodiment 2, the main difference is that: it also includes baffles 3 and threading pipes 5, through multiple baffles 3 and threading pipes 5, each baffle plate 3 is correspondingly arranged above the micro pressure transmitter 2 to cover the micro pressure transmitter 2 and protect it, which can effectively prevent it from being damaged by high temperature and fire. It is beneficial to ensure its use effect and improve the service life of the pressure transmitter.
[0055] Specifically, such as figure 2 and Figure 5-8 As shown, the baffle plate 3 is composed of a top plate and side plates vertically distributed along the two opposite sides of the top plate. The top plate of the baffle plate 3 is processed with 31 first bolt through holes, which span the threading pipe 5 and connect with the threading pipe 5. It is detachably con...
