Embodiment Construction

[0016] A specific implementation method of a device for preventing scaling of milk of lime in the smelting desulfurization system will be described below in conjunction with the accompanying drawings.

[0017] A device for preventing scaling of lime milk in a smelting desulfurization system, comprising a raw slurry tank 1, an aeration tank 2, a mixer 3, a slurry pump 4, a first slurry pump pipeline 5, a second slurry pump pipeline 6, a first Lime chute 7, second lime chute 8, first lime liquid diverter valve 9, second lime liquid diverter valve 10, first PH value automatic detection device 11, second PH value automatic detection device 12, first water level monitor 13 , The second water level monitor 14.

[0018] The first slurry pump 41 pumps the milk of lime in the aeration tank 2 to the first reaction tower 15 of the DS multiple reactor through the first slurry pump pipeline 5. A lime chute 7 circulates into the aeration tank.

[0019] A second slurry pump 42 is installed...

Abstract

Disclosed are a device and method of preventing lime milk in a smelting desulfurization system from scaling. The device comprises a raw slurry pond, an aeration pond, mixers, slag-slurry pumps, slag-slurry pump tubes, lime chutes, lime milk automatic splitters, automatic pH testing apparatus and water level monitors. The device and method of preventing lime milk in the smelting desulfurization system from scaling provided by the invention realize timed discharging of water and slag of lime milk in a DS multiphase reactor, solve the problem that the lime milk is deposited and scales in the raw slurry pond, the aeration pond and DS tower sections, the problem of low utilization rate of the lime milk, the problem of production cost, the problem of environmental pollution and the problem of occupational hazard.

Description

technical field [0001] The invention belongs to the field of non-standard equipment for anti-scaling of lime milk for treating three wastes in smelting, and relates to a device and method for preventing scaling of lime milk in a smelting desulfurization system. Background technique [0002] In the smelting three wastes (waste gas, waste water, waste slag) treatment process, the circulating lime milk used in DS multiple reactors contains a large amount of iron powder (lime milk is made by ball milling), and the lime emulsion reacts with flue gas to form calcium carbonate precipitation , entered the raw slurry pool and aeration tank during the circulation process, and regular manual inspection and pumping of lime waste liquid and waste residues are required. A large number of lime milk blocks are easily bonded in the raw slurry tank, aeration tank, and DS tower section, solidifying It is difficult to clean up afterward, which affects the normal treatment of flue gas. Wastewat...
