The water inlet filter in the cryogenic chamber of the space furnace is clogged
Thread Content
Urgent help: Vaporization furnace: Space furnace. Due to the sudden deterioration in coal quality recently, severe blockages have occurred in the quenching ring, as well as in the ash water filters from the scrubber tower to the quenching chamber. This in turn leads to a decrease in the liquid level in the quench chamber, forcing the system to operate at reduced capacity. Question: If maintenance is to be carried out without stopping the machine, what are some good ways to remove the scale from the filter? The scale is mainly composed of silicates. Are there any other good ways?
Is the filter cartridge damaged? Why does scaling occur so quickly during the operation of the quench ring? Is there a spare for the black water filter? If so, cut one out, remove the flange, and take out the filter frame to clean it. If the quench ring gets blocked, there’s nothing that can be done. You can try increasing the flow of emergency quench water and see what happens – it’s a shot in the dark!
Use a fully automatic filter, one in use and one as a backup. For any questions, please contact 15002150001
Fully automatic filters are probably not suitable for the coal chemical industry!
Thank you for your advice. There is no spare filter at the moment, and the downtime for maintenance at the company is too short; the system was put back into operation without proper cleaning. I’m really having a headache right now. First, increase the amount of accident quench water and give it a try.
Let’s discuss technology now; those who are in the advertising business, please refrain from interrupting. Thank you!
Coolant water is injected in case of an accident; as long as the liquid level in the vaporizer remains stable, the cooling ring can be sacrificed to keep operations going until the end, after which the unit can be shut down for maintenance
Thank you! Currently, accident quench water has been continuously supplied. However, due to scaling in the pipeline from the quench chamber to the high-flash point unit, the water output flow rate also decreased, coupled with a reduction in the water inflow flow rate from the scrubber tower to the quench chamber. At present, the system can only operate at reduced load; under normal conditions, the load should be at 100-110%. And currently, it can only reach over 90%. With current high profits in the chemicals industry, management requires full capacity operation. It’s really difficult to solve these problems during operation!
What kind of furnace do you have, and how long has it been in use? The gasification furnace’s grates shouldn’t get clogged that severely! The accident cooling water kept flowing into the large tank
The space furnace has been in operation for five or six years, and it has always worked properly. At the beginning of the year, the poor quality of coal led to various problems. The maintenance time was short, and there was no time to clean the dust.
Increase the amount of quench water used in the accident handling; raise the discharge volume from the quench chamber wash towers to improve water quality, and increase the external discharge volume
