Problems solved by technology

Although these methods can realize the treatment of barium slag, the utilization rate of barium slag is very low due to the relatively complicated production process and the small amount of treatment; and the above treatment methods are usually simply mixed with barium slag and other substances. , did not remove the toxicity of the barium slag, resulting in the processed barium slag is still dangerous

Embodiment 1

[0025] Embodiment 1: A barium slag processing system, including a crusher, a cyclone furnace, a primary dust collector, a secondary dust collector, desulfurization equipment and a water quenching water tank, wherein the cyclone furnace is WGZ260 / 9.8-1 type cyclone furnace , the primary dust collector is a double-chamber four-field electrostatic precipitator; the secondary dust collector is a bag filter, and the desulfurization equipment is a semi-dry desulfurization equipment. The discharge port of the crusher is connected with the feed port of the cyclone furnace, and the slag discharge port of the cyclone furnace is connected with the water quenching water tank; the dust collection port of the primary dust collector is connected with the cyclone furnace. The smoke outlet of the furnace is connected; the primary dust collector also includes a fly ash outlet and a flue gas outlet, the fly ash outlet is connected with the feed port of the cyclone furnace, and the flue gas outlet...

Embodiment 2

[0026] Embodiment 2: a kind of method that uses the barium slag treatment system in embodiment 1 to carry out barium slag treatment, see figure 1 , including the following steps:

[0027] (1) Raw material crushing: Mix barium slag and raw coal at a weight ratio of 1:9, and crush the obtained mixture to a powder with a fineness of R90=16% using a crusher.

[0028] (2) High temperature combustion: the operating temperature is 160°C and the flow rate is 86888m 3 / h, hot air with a flow rate of 30-35m / s sends the mixed powder obtained in step (1) into the cyclone furnace for combustion at a temperature of 1600°C, and forms molten slag after full combustion.

[0029] The cyclone furnace used is WGZ260 / 9.8-1 type cyclone furnace (liquid slag discharge furnace). The rotary cylinder adopts segmental combustion. After the coal powder and barium slag enter the cyclone cylinder with the primary wind, they rotate and fall, and the secondary wind also flows along the furnace wall. It ent...

Abstract

The invention discloses a barium slag processing system and method which are thorough in detoxication, high in processing efficiency and high in resource recycling rate. The barium slag processing system comprises a crusher, a cyclone furnace, a primary dust remover, a secondary dust remover, a sweetener and a water quenching water tank. The barium slag processing method includes the following steps of (1) raw material crushing, (2) high-temperature combustion, (3) smoke processing and fly ash remelting and (4) water quenching and sealing. Barium slag processed through the processing system and method is detoxified thoroughly and has no secondary pollution. Water quenching slag obtained after detoxication can serve as auxiliary materials for producing cement or can be used for paving roads, making construction materials and the like, so that recycling of waste slag is facilitated. Heat generated in the combustion process of the cyclone furnace can be applied to chemical industry production, and both economic and environmental protection benefits are gained.

Description

technical field [0001] The invention relates to the technical field of industrial waste slag treatment, in particular to a barium slag treatment system and treatment method. Background technique [0002] Barium slag is the residual solid produced in the production process of barium salt. It is a dangerous industrial waste. Stacking of barium slag will pollute the environment and damage human health. In particular, water-soluble barium in barium slag can easily seep into groundwater, causing Ba 2+ If it exceeds the standard, it will cause poisoning after drinking. Therefore, the safe disposal of barium slag is an important issue in industrial production. The existing common methods for disposing of barium slag include physical methods and chemical methods. Physical methods include using barium slag as a cement admixture and as a component of aerated concrete. , as a component of fly ash blocks or made into barium slag bricks, etc.; chemical methods such as using barium slag ...
