The line blowing system can be divided into two forms of pressure difference control and on-time control according to the control form.
First, pressure difference control
When the online differential pressure transmitter detects that the pressure difference between the inlet and the outlet (equipment resistance, namely the resistance of the filter tube) is greater than a set value M, the blowing system starts to operate and blows the filter tube until the pressure difference between the inlet and the outlet (equipment resistance) is less than a set value N.
The blowing process is as follows:
1. and opening a No. 1 pulse valve on the gas distribution box, and allowing compressed air to enter the injection pipe from the gas distribution box through the bent pipe.
2. Compressed air is sprayed downwards from a nozzle on a spray pipe, and is guided by an air inlet pipe to spray and clean the 1 st row (20) of filter bags.
3. And after the 1 st row of filter bags are subjected to blowing cleaning, the No. 1 pulse valve is closed, and the gas distribution box is used for supplementing gas within a set time.
4. And opening a No. 2 electromagnetic valve on the air distribution box, and performing spray-blow cleaning on the 2 nd row (20) of filter bags.
5. And analogizing until all the pulse valves on the gas distribution box complete blowing. At the moment, if the pressure difference (equipment resistance) between the inlet and the outlet is still larger than the set value N, the blowing weighing is repeated until the pressure difference is smaller than the set value N, and the blowing is stopped.
Secondly, controlling on time
When the control system detects that the dust remover runs for K hours in a specified time period, the injection system starts to run to inject the filter bag (filter tube), and the injection process is the same as the above. And stopping until the set blowing period is completed.
In practical use, the two control modes can be used separately or in combination. During combined control, the blowing system is started when any starting condition is met, and blowing is stopped only when two finishing conditions are met simultaneously.
