In general, calcium chloride (CaCl 2 ) is mixed with various desiccants, snow removal, medical, electronic materials, concrete, mixed with concrete to prevent freezing, production of decolorized coal, dehydration of solvents, snow removal, food additives And so on.
As a manufacturing method of calcium chloride, there existed the industrial manufacturing method using the ammonia-soda method (Solvay method). This was done by a chemical synthesis method such as concentrating the waste solution of the ammonia distillation column, or producing calcium chloride as a by-product in preparing sodium chlorate by the lime method, in which case calcium chloride is produced in the form of by-products. There was a problem that the purity was somewhat lower.
In addition, a method of preparing calcium chloride using a shell has been introduced, but there is a problem in that the manufacturing process is complicated due to the purification and filtration steps.
In order to solve this problem, the present invention by using the animal bones discarded as waste to produce calcium chloride used for snow removal to prevent environmental pollution due to landfilling of animal bones at the same time calcium chloride using a simple animal bone production method Its purpose is to provide a method of manufacturing.

First, in adding reference numerals to constituent elements of each drawing, it should be noted that the same constituent elements are denoted by the same reference numerals even though they are shown in different drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

Referring to Figure 1 when explaining a method for producing calcium chloride using bones as follows. The heating step is a step of removing the organic matter present in the animal bone by heating the animal bone (S110). Here, the animal bone refers to the bones of chickens that are usually consumed the most, but the bones of other animals may also be used. Heating animal bones at high temperatures removes organic matter from animal bones, leaving only quicklime, or calcium oxide (CaO). The heating step includes heating the animal bone and then grinding the heated animal bone.
In addition, the heating step can be classified in more detail, as shown in FIG. That is, the heating step is the primary heating step (S111) for heating the animal bones primarily, the grinding step (S112) for grinding the animal bones heated in the first heating step and the animal bones undergoing the grinding step 800 ~ Secondary heating step (S113) for secondary heating at 1000 ℃. The reason for the second heating step after the crushing step is to completely remove the organic matter that was not removed in the first heating step. The reason for heating in the temperature range of 800 ~ 1000 ℃ is that the animal bones may not be completely incinerated if the temperature is less than 800 ℃, if the temperature is more than 1000 ℃ can be a waste of excessive energy for incineration of animal bones. Because there is.
The dissolution step is a step of dissolving the animal bone heated in the heating step in water to generate an animal bone solution (S120). That is, when water is dissolved in heated animal bones (CaO), calcium hydroxide is produced. The reaction scheme in the dissolution step is as follows.
CaO + H 2 O → Ca (OH) 2
The injection step is a step of injecting carbon dioxide into the animal bone solution (Ca (OH) 2 ) (S130). That is, when carbon dioxide (CO 2 ) is injected into the aqueous animal bone solution, calcium carbonate aqueous solution is produced. Here, the carbon dioxide is directly injected, but even if the air is injected, the same effect as in this step will be caused by the carbon dioxide contained in the air. The reaction scheme in the injection step is as follows.
Ca (OH) 2 + CO 2 → CaCO 3 + H 2 O
The production step is a step of generating a calcium chloride aqueous solution by adding hydrochloric acid to the animal bone aqueous solution undergoing the injection step (S140). That is, when hydrochloric acid is added to the aqueous solution of calcium carbonate, an aqueous solution of calcium chloride is produced. The aqueous calcium chloride solution is liquid calcium chloride, which is much more convenient to use than calcium chloride in the solid state, and is much more efficient in snow removal operations. The reaction scheme in the production step is as follows.
CaCO 3 + 2HCl -> CaCl 2 + H 2 O + CO 2
As shown in the reaction scheme, since carbon dioxide is generated in addition to calcium chloride (CaCl 2 ), it can be reused again, and thus it is not necessary to add additional carbon dioxide. In particular, in the conventional method for producing calcium chloride, it was difficult to remove unnecessary carbon dioxide, but in the present invention, since the carbon dioxide is injected at the step of injecting carbon dioxide and the finally produced carbon dioxide can be reused, the conventional carbon dioxide is generated. It is much more economical and efficient than the method.
Hereinafter, the present invention will be described in more detail with reference to examples. However, the Examples are for illustrating the present invention, not to limit the invention only to the following examples.
[Example]
Chicken bones are first heated with a crucible and a torch to remove organic matter and other impurities, and then pulverized and heated at 900 ° C. for 1 hour using a secondary electric furnace. Because it is an experiment in the laboratory, the primary and secondary heating were separated and processed, but it would be possible in a single process in an incinerator (first process).
0.2 g of the processed bone produced in the first step is dissolved in 100 ml of water. Bone and water processed during the dissolution process are dissolved by forward reaction. However, since the dissolution process proceeds through proper stirring (stirring time 10 minutes), the processed bone is almost completely dissolved (second process).
Air is blown into the solution produced in the second step. If pure carbon dioxide is injected, high efficiency can be obtained for a short time, but air will be injected in consideration of the increase in unit cost. Even if air is injected, it is irrelevant to the process because it selectively reacts with carbon dioxide in the air, but the reaction time is long because the amount of carbon dioxide in the air is small. Therefore, in consideration of sufficient reaction time, it reacted for 60 minutes in an experiment (3rd process).
Hydrochloric acid is added to the aqueous solution of the third step to form an aqueous calcium chloride solution. 0.494 ml of hydrochloric acid (35% weight concentration) is injected based on 0.2 g of processed bone. At this time, if the reaction amount is increased, the heat may be generated (step 4).
On the other hand, the X-ray diffraction analysis of the liquid calcium chloride prepared according to the [Example] is as shown in Figure 4, compared with the conventional X-ray diffraction analysis of calcium chloride of Figure 3, the liquid calcium chloride prepared according to the present invention It can be seen that the purity is much higher.
Therefore, the method for producing calcium chloride using the animal bone according to the present invention is not only simpler than the conventional solid-state calcium chloride, but also has excellent purity, which can greatly increase the efficiency of snow removal when used for snow removal. It works.
In addition, the present invention is composed of a process capable of reusing carbon dioxide, unlike the conventional method for producing calcium chloride by the generation of additional carbon dioxide can be seen not only environmentally friendly but also excellent in terms of economics.
