More Details

Intellectual property name: an on-line injection control method of bag filter

Corresponding product or project: ultra low emission project of Zhongsheng Engineering Technology (Tianjin) Co., Ltd

Core technology: after the dusty gas enters from the upper air inlet of the ash hopper, the airflow is guided by the airflow distribution plate to flow upward, the flow rate is reduced, and some large particle dust is separated and falls into the ash hopper due to the action of inertial force. The dusty gas enters the middle box and is filtered and purified by filter bags with different performance parameters. The dust is blocked on the outer surface of the filter bag. The purified gas enters the upper box through the filter bag mouth and is discharged from the air outlet. With the increasing dust on the surface of the filter bag, the pressure difference between the inlet and outlet of the dust collector also increases. When the negative force of the dust collector reaches the set value, the control system sends out the ash cleaning command and the ash cleaning system starts to work. Firstly, the solenoid valve is opened immediately after receiving the signal, so that the compressed air in the upper air chamber of the small diaphragm is discharged. Due to the change of the force at both ends of the small diaphragm, the exhaust channel closed by the small diaphragm is opened, and the compressed air in the upper air chamber of the large diaphragm is discharged from this channel. The force at both ends of the large diaphragm is changed, so that the large diaphragm acts, the closed output port is opened, and the compressed air in the air bag is sprayed into the bag through the output pipe and blowing pipe to realize ash cleaning. When the control signal stops, the solenoid valve is closed, the small diaphragm and the large diaphragm are reset successively, and the injection stops.

Technical indicators reached: the emission concentration of smoke and dust at the outlet of dust collector is less than 10mg / Nm3
