Description
Technical Field
The utility model relates to a sack cleaner on-line monitoring technique especially relates to a thermal power factory sack cleaner jetting pulse valve on-line monitoring system.
Background
The smoke concentration of the thermal power plant is required to meet the national environmental protection ultralow emission, the bag-type dust collector is indispensable important equipment, and the running state of the bag-type dust collector is related to whether the environmental protection emission index is qualified or not and the thermal generator set runs safely and stably. The bag-type dust collector is a flue gas and dust filtering device mainly composed of a plurality of bag chambers, and the principle of one chamber is shown in figure 1. The original flue gas (flue gas containing dust) filters dust in the flue gas through a cloth bag of a bin, the later flue gas is called clean flue gas, the dust in the original flue gas is adsorbed on the cloth bag, if the dust on the cloth bag can not fall into an ash bucket, the permeability of the cloth bag is deteriorated due to long-time operation, the flue gas can not pass through the cloth bag, meanwhile, too much powder can be accumulated, the weight of the cloth bag is increased, the cloth bag falls, the cloth bag dust remover can not filter the dust, and finally, the environment-friendly emission index exceeds the standard. In order to solve the problem, a pulse valve is arranged at the top of each chamber of the bag-type dust collector, the pulse valve is controlled by an electromagnetic pilot valve, and when an electromagnetic coil is electrified, a diaphragm valve which can instantly open a high-pressure air source to generate pulses is arranged. Through the pulse air supply, the dust adsorbed on the bag is vibrated to fall into the dust hopper at the lower part, the pulse valve is an important component of the bag-type dust remover, and the running condition of the pulse valve plays a vital role in the bag-type dust remover.
Because the pulse valve moves frequently, the number of times of movement is about 10000 every day, and the fault is easy to occur in the operation process, and the common faults are 4 kinds as follows:
1. the spring is damaged, and the spring on the valve core of the pulse valve is easy to damage, so that the pulse valve is shown to deflate to the blowing opening for a long time;
2. the rubber mat is damaged, and after the use time is long, the rubber mat on the valve core of the pulse valve is easy to damage, so that the phenomenon that the pulse valve deflates to the blowing opening for a long time is caused;
3. the valve core is accumulated with dirt, and the dirt at the valve core is accumulated due to unclean air inlet, so that the appearance that the air inlet of the blowing opening is long-term or the pulse valve does not work after the power is on is caused;
4. after the diaphragm is damaged and works for a long time, the diaphragm is easy to fatigue, oxidize and the like, the pressure relief port is deflated for a long time, and the pulse valve does not work.
In the operation process, an operation operator cannot judge whether the pulse valve of the bag-type dust collector normally acts in a remote control room, and can judge whether the pulse valve fails only by checking the operation condition of the pulse valve on site, and the failure of the pulse valve cannot be timely found due to the influence of factors such as inspection cycle time and the like, so that great hidden danger is caused to the safe and stable operation of the bag-type dust collector. In the prior art, a pressure gauge is arranged on a blowing air source pipeline at the inlet of a pulse valve, and an operation operator observes the reading of the pressure gauge on the spot to judge whether the pulse valve works normally or not, so that the operation condition of the pulse valve cannot be monitored in real time.
