Abstract
The present invention discloses a method for treating waste material produced by using chloropropanol method to prepare epoxypropane. The described waste material includes Ca(OH)2, CaCO3 and CaCl2. Said method includes the following steps: (1), filter pressing said waste material to obtain lime mud; (2), storing said lime mud for 15-45 days at room temperature under the condition of ventilation; and (3), adding Ca(OH)2 or cement in said lime mud, the weight ratio of lime mud and cement or Ca(OH)2 is 1:0.5-2.
Description
Technical field
The present invention relates to the processing method of waste material that a kind of Chemical Manufacture produces, especially a kind of new processing method to handling and being used.
Background technology
In the prior art, the production method of expoxy propane is wherein a kind of to be the chloropropyl alcohol method, promptly makes chloropropyl alcohol with propylene, chlorine G﹠W, makes chloropropyl alcohol dehydrochlorination (saponification) obtain expoxy propane with milk of lime then, with the preparation expoxy propane is example, and its reaction equation can be expressed as follows:
Course of reaction produces product after reclaiming expoxy propane, remains raffinate by analysis, and its main component and content are:
Ca (OH)
2: 4-7%; CaCO
3: 10-11%; CaCl
2: 15-20%; All the other are water.
By reaction equation as can be known, reacted waste material main component is Ca (OH)
2, CaCO
3And CaCl
2, the active calcium ion content wherein is higher, but because water content is also higher, contains the chlorine element again, therefore can't directly use as lime paste, only transports to suburb or other storage places.So, not only need to spend more freight, and take the large tracts of land soil, both corroded the soil, wasted the useful composition in the residue again.
Summary of the invention
The objective of the invention is to be equipped with the waste material that expoxy propane produces to the chloropropyl alcohol legal system and effectively to handle at what exist in the prior art, the deficiency that can't reuse simultaneously provides a kind of new processing method that can be used to the active calcium ion content in the waste material
Technical scheme of the present invention is: a kind of chloropropyl alcohol legal system is equipped with the processing method of the waste material that expoxy propane produces, and comprises Ca (OH) in the described waste material
2, CaCO
3And CaCl
2, it is characterized in that may further comprise the steps,
(1) the chloropropyl alcohol legal system is equipped with the waste material press filtration that expoxy propane produces and obtains lime slurry;
(2) the gained lime slurry was placed 15-45 days under room temperature and ventilated environment;
(3) in step (2) gained lime slurry, add Ca (OH)
2Or cement, lime slurry and cement or Ca (OH)
2Weight ratio be 1: 0.5-2.
Preferably, described lime slurry was placed 20-25 days under room temperature and ventilated environment.
Preferably, in step (3), lime slurry and the cement or the Ca (OH) that are added
2Weight ratio be 1: 08-1.1.
Preferably, in step (3), lime slurry and the cement or the Ca (OH) that are added
2Weight ratio be 1: 1.
Beneficial effect of the present invention is: solved the waste residue that is produced in the technical process of chloropropyl alcohol method production expoxy propane and handled problems, and easy to operate, save the soil, and waste residue can be used as the construction material use after handling, and turns waste into wealth, and has reduced waste.
