Detailed Description
The technical solutions in the embodiments of the present invention are clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention. Details which are not described in detail in the embodiments of the invention belong to the prior art which is known to the person skilled in the art.
Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a wet flue gas desulfurization absorption tower overflow pipe anti-clogging device, comprises draught fan 3, desulfurizing tower 1, overflow pipe 10 and washing unit 5, 1 the left side of desulfurizing tower is provided with former flue gas entry 2, is provided with overflow mouth 4 behind, draught fan 3 and former flue gas entry 2 intercommunication, overflow pipe 10 is connected with overflow mouth 4 and water seal tank 11, installs electric butterfly valve 9 on the overflow pipe 10, washing unit 5 is connected with overflow pipe 10, introduces the sparge water, installs butterfly valve 6, manometer 8 and flowmeter 7 on 5 water pipelines of washing unit.
A liquid level line is arranged in the desulfurizing tower 1, the low level line is a normal liquid level line and is 12 +/-0.5 m, the middle level line is the distance from the bottom of the desulfurizing tower to the lower end of an overflow port and is 13.4m, and the high level line is the distance from the bottom of the desulfurizing tower to the lower end of an original flue gas inlet and is 14.5 m.
The desulfurization tower 1 is internally provided with a filler ball 11, and the top of the desulfurization tower 1 is provided with a spray header 12.
The diameter of the packing ball 11 is 3-6cm, the packing ball 11 comprises a support frame 13, the support frame 13 comprises support rods 14 and support balls 15, the support balls 15 are arranged on the center of the packing ball 11, the support rods 14 are arranged on the peripheral walls of the support balls 15, the included angle between every two adjacent support rods 14 is 45 degrees, and arc-shaped sheets 15 are arranged at the top ends of the support rods 14.
The number of the spray headers 12 is 3, and the angle between the adjacent spray headers 12 is 30-45 degrees.
The working principle is as follows: after the overflow pipe and the tower wall are connected and blocked, the flushing device can flush at once, and whether the overflow pipe is blocked or not is judged through pressure and flow during regular flushing, so that the equipment is timely treated and is guaranteed to be reliable.
Install electronic butterfly valve additional on the overflow pipe, introduce the sparge water, install butterfly valve, manometer and flowmeter additional on washing unit water pipe. Normally can arrange to the water seal tank through the overflow pipe during absorption tower overflow, overflow pipe and tower wall junction have thick liquid partial deposit behind the overflow, and after the many times overflow, the overflow pipe is piled up with tower wall junction deposit and is grown up, can cause overflow pipe and tower wall junction to block up for a long time. When the overflow pipe is blocked, the butterfly valve on the overflow pipe is closed, and the butterfly valve on the water pipeline of the flushing device is opened for flushing. Whether the blockage exists can be judged through the reading of the pressure gauge and the flowmeter. If the pressure is high and the flow is low, the blockage is caused, and the flushing time is prolonged until the normal flushing is realized. (the diameter of an overflow pipe of each tower and the diameter of introduced flushing water are different, and pressure and flow data obtained by a test after installation are used as fixed values), the effect is good when the tower runs for more than one year at present.
