Problems solved by technology

[0004] In view of the above problems, the object of the present invention is to provide a comprehensive utilization process of calcium carbide slag slurry water, by performing different treatments on the proportion of the supernatant liquid after the calcium carbide slag slurry water settles, the classification utilization of the supernatant liquid is realized, and by The supernatant containing a lot of impurities is treated as water for the acetylene generator, which can realize the closed-loop comprehensive utilization of calcium carbide slag slurry water, and solve the problem of large supernatant recovery and water consumption of acetylene generators in the traditional comprehensive utilization process of carbide slag slurry water. Less, and thus can not cause the problem of water balance

Embodiment 2

[0034] according to Figure 1-2 As shown, this embodiment proposes a comprehensive utilization process of calcium carbide slag slurry water. The mixed supernatant filtrate obtained after mixing and settling in the second settling tank is cooled by a spray cooling device and then used as water for the acetylene generator. The mixed supernatant filtrate is cooled by spraying When the device is cooled and used as water for the acetylene generator, it needs to be mixed with fresh water in a ratio of 1:4 before use, and the mixed supernatant filtrate after cooling needs to be filtered before being used as water for the acetylene generator. In the mixed supernatant filtrate, the filtration process is carried out in the form of multi-stage filtration. Before using the mixed supernatant filtrate, first measure the impurity content in the mixed supernatant filtrate, and determine the number of filtration stages according to the impurity content. When the mixed supernatant filtrate If t...

Embodiment 3

[0036] according to Figure 1-2As shown, this embodiment proposes a comprehensive utilization process of calcium carbide slag slurry water. The mixed supernatant filtrate obtained after mixing and settling in the second settling tank is cooled by a spray cooling device and then used as water for the acetylene generator. The mixed supernatant filtrate is cooled by spraying When the device is cooled and used as water for the acetylene generator, it needs to be mixed with fresh water in a ratio of 1:5 before use, and the mixed supernatant filtrate after cooling needs to be filtered before being used as water for the acetylene generator. In the present invention In the mixed supernatant filtrate, the filtration process is carried out in the form of multi-stage filtration. Before using the mixed supernatant filtrate, first measure the impurity content in the mixed supernatant filtrate, and determine the number of filtration stages according to the impurity content. When the mixed su...

Abstract

The invention discloses a carbide slag slurry comprehensive utilization process, which relates to the technical field of carbide slag treatment, and comprises the following steps: recovering 2 / 3 depth of supernatant into a first clear water tank, carrying out filter pressing on the supernatant in the first clear water tank by a filter press, discharging first supernatant filtrate into a second sedimentation tank for sedimentation, recovering 1 / 1 of the first supernatant filtrate in the second sedimentation tank, and discharging the first supernatant filtrate into a second sedimentation tank for sedimentation. Carrying out deep processing on the recovered first supernatant filtrate, carrying out filter pressing on the supernatant in the second clear water tank by a filter press, and discharging the second supernatant filtrate to a second sedimentation tank for mixing and natural sedimentation; according to the method, the supernate obtained after settlement of the carbide slag slurry is subjected to different treatment in proportion, classified utilization of the supernate is achieved, the supernate with the large impurity content is treated to serve as water for an acetylene generator, closed-loop comprehensive utilization of the carbide slag slurry can be achieved, and the utilization rate of the acetylene generator is increased. The problems that in a traditional carbide slag slurry comprehensive utilization process, the recovery amount of supernate is large, the water consumption of an acetylene generator is small, and then water consumption balance cannot be generated are solved.

Description

technical field [0001] The invention relates to the technical field of carbide slag treatment, in particular to a process for comprehensive utilization of calcium carbide slag slurry water. Background technique [0002] At present, tens of millions of tons of calcium carbide slag are produced in my country every year, and the stacking of strong alkaline carbide slag not only occupies a large amount of land, but also because calcium carbide slag is easy to lose and spread, pollute the water resources near the stacking site and alkalize the land, and it may be possible to stack it for a long time Air-dried and dusty, polluting the surrounding environment. Therefore, the resource utilization of carbide slag is imminent. Traditional carbide slag is mainly used to produce cement and other building materials, but the cement industry has serious overcapacity and economic sluggishness. [0003] At present, the recycling process of calcium carbide slag water is to separate calcium c...
