Embodiment 1

[0070] A device for preparing calcium silicate hydrate and magnetic hydrotalcite from industrial waste, The first part is white mud, high sulfur coal Burn activation system: In the fluidized combustion device (1-1), the middle and lower part of the side wall of the fluidized combustion chamber (1-1-1) is respectively equipped with a high-sulfur coal white mud mixture feed port (1-1-2) and a fluidized combustion chamber lime mud The feed inlet (1-1-3), the upper part of the side wall is equipped with a flue gas discharge port (1-1-4) and a superheater (1-1-5), and the lower part of the fluidized combustion chamber (1-1-1) The air distribution pipe (1-1-6) is connected to the first fan (1-1-7), and the bottom of the fluidized combustion chamber (1-1-1) is provided with a first outlet (1-1-8) ;The lime mud preheating device (1-2) is equipped with the lime mud gas-solid mixer (1-2-1) and the lime mud conveyor (1-2-2); the lime mud conveyor (1-2-2) The upper part is equipped wi...

Embodiment 2

[0076] This embodiment is basically the same as Embodiment 1, and is characterized in that the first part is the first opening (1-2-5) and the second opening in the lime mud preheating device (1-2) of the high-sulfur coal combustion activation system. (1-2-6) and the third opening (1-2-13); the distance between adjacent openings is greater than the distance between the two closest edge co-location points of the screw propeller (1-2-3); the The co-location point of the edge is the contact point between the screw propeller (1-2-3) and the horizontal plane when the screw propeller (1-2-3) is placed on the horizontal plane.

[0077] In this embodiment, the distance between 3 openings is set to prevent the lime mud from entering the relevant gas path when it enters the lime mud gas-solid mixer (1-2-1); at the same time, it can prevent the gas from entering other pipelines.

Embodiment 3

[0079] This embodiment is basically the same as Embodiment 1, and it is characterized in that the angle between the direction of the exhaust port of the third fan (1-4-5) in the high-temperature calcination device (1-4) and the discharge pipe (1-4-2) 30-60 degrees; preferably 45 degrees.

[0080] If the angle is too small, it will accelerate the cooling of the material in the discharge pipe (1-4-2), making it difficult to discharge; if the angle is too large, the horizontal head of the material will be too large, and the cooling will not be sufficient.

Abstract

The invention discloses equipment using industrial waste to prepare calcium silicate hydrate and magnetic hydrotalcite, relates to industrial waste treatment equipment, and particularly relates to the technical field of equipment for comprehensively utilizing industrial waste such as fly ash, white mud and waste acids and synthesizing sewage and waste liquid treatment materials. The equipment comprises a white mud and high-sulfur coal combustion and activating system, a distillation system, a distillation and extraction system, an extraction and separation system and a synthesizing and 'three waste' treatment system. The equipment has the advantages that a fluidized bed and a rotary kiln are ingeniously combined to achieve the technical effect of energy saving and environment protection; waste treatment is achieved while corresponding components are separated and purified by improving waste acid distillation equipment and waste extraction equipment; effective 'three-waste' treatment is achieved by improving tail gas discharge equipment and mother liquor treatment equipment.

Description

technical field [0001] The invention relates to industrial waste treatment equipment, in particular to the technical field of comprehensive utilization of fly ash, lime mud, waste acid and other industrial waste and synthesis equipment for sewage and waste liquid treatment materials. Background technique [0002] Components and hazards of high-sulfur coal, lime mud and waste acid . 1 Composition of high-sulfur coal and its hazards: High-sulfur coal refers to coal with a sulfur content greater than 3%. About 8% of my country's coal resources are high-sulfur coal. The acid mist generated by direct combustion will pollute the atmosphere and cause serious environmental pollution , simple desulfurization treatment will increase production costs, so high-sulfur coal treatment is a bottleneck problem that has plagued the development of related industries in my country for a long time. Desulfurization of high-sulfur coal mainly adopts three methods: desulfurization before use, desu...
