The addition method may be a method using gravity or transfer using a pump. Immediately after the addition, a reaction begins in the system and the temperature becomes high due to the heat of reaction.

なるように行う。 In the present invention, these materials are cooled by circulating them between a cooler (condenser) and a closed container through a duct. The pressure within the apparatus increases due to the heat of reaction, but the cooling in the cooler absorbs and removes the heat of reaction, preventing the pressure from increasing in the reaction system. The condensate condensed in the cooler is circulated into the mixer by a pump and used again as a raw material. This cooling is performed such that the temperature of the gas discharged from the cooler is below 100°C, preferably below 50°C.

去が行われ、反応系内の圧力上昇が防止される。 To carry out the present invention, as shown in FIG. 1, first, a fixing agent is charged into a mixer (closed type stirring container) 1 in advance. Next, while operating the mixer, the liquid organic halide is pumped into the mixer 1 through the conduit 4 and water is pumped into the mixer 1 through the conduit 5 to start the immobilization process of the liquid organic halide. With this process,
The temperature in the reaction system increases and the pressure in the apparatus increases, but in the present invention, the blower 3 is operated to remove the organic halide vapor and water vapor present in the space of the mixer 1, as well as the scattered immobilization. The gas containing the fine powder of the agent is passed through the first duct 6, the cooler 2 and the second duct.
It is circulated through the duct 8 to the mixer 1 for processing. Through this circulation process, the organic halide vapor generated in the mixer 1 is condensed together with water vapor in the cooler 2, resulting in a condensate.
accumulates at its bottom 7. In this case, the fine powder of the fixing agent is also trapped in this condensate. The condensate is circulated by pump 10 through conduit 9 to mixer 1 . By providing the cooler, the heat of reaction is absorbed and removed, and pressure rise within the reaction system is prevented.

When such a gas adsorption treatment device 16 is attached, the rapid reaction causes insufficient absorption and removal of the reaction heat by the cooler, and the pressure of the reaction system temporarily rises above the set pressure, causing the pressure regulating valve 15 to close. When opened and the gas is discharged out of the system, the gas will be discharged to the atmosphere through the adsorption treatment device 16. Therefore, the gas released into the atmosphere does not contain any organic halides, making it possible to perform extremely safe processing. As the adsorbent in the adsorption treatment apparatus, any adsorbent can be used as long as it exhibits adsorption to organic halides, but activated carbon is generally used.

It was fed into mixer 1. In this case, the initial feed rates are: chlorinated paraffin: 1.4/min and water: 0.86
/min, and then, while keeping the ratio of chlorinated paraffin and water constant, the feed rate was gradually reduced to 0.28/min for chlorinated paraffin and 0.17/min for water. When the total feed amount thus reached 15 chlorinated paraffin and 99 water, the feed was stopped. During this reaction, the temperature of the powder in the mixer rises to 200℃,
The pressure inside the device rose to 0.1 Kg/cm 2 G, but by operating the blower 3 and circulating the gas inside the mixer through the cooler 2, it was possible to return it to the original atmospheric pressure. In addition, in this case, the set pressure of the pressure regulating valve 15 was set to 0.15Kg/cm 2 G, so
The valve did not open, and liquid chlorinated paraline could be immobilized without exhausting gas outside the device.

Next, while the mixer was running, the valves connected to those tanks were opened to supply chlorinated paraffin and water into the mixer.
In this process, the blower 3 was operated to circulate the gas for cooling, but the temperature of the powder rose to 160°C due to the heat of reaction, and the pressure inside the device was 0.2Kg/cm 2 G.
Pressure valve 15 rose to 0.15Kg/cm 2 G.

求の範囲第２項の装置。[Scope of Claims] 1. A method for immobilizing a liquid organic halide with a calcium oxide and/or magnesium oxide-based immobilizing agent in the presence of water, in which the immobilizing treatment of the liquid organic halide with the immobilizing agent is tightly controlled. At the same time as carrying out in a mold container, cooling the gas containing liquid organic halide vapor, water vapor and fine powder generated in the container, and condensing the liquid organic halide vapor and water vapor contained in the gas, A method for immobilizing a liquid organic halide, characterized in that fine powder in the gas is captured in the condensate, and the condensate containing the fine powder is circulated in the closed container and reused. 2. A closed container having a liquid organic halide supply port, a water supply port, a circulating condensate inlet, a fixed processed material discharge port, a gas discharge port, and a circulating gas inlet,
a gas cooling device, a first duct that connects the gas outlet of the container and the gas cooler, and a second duct that connects the circulating gas inlet of the container and the cooler;
A blower attached to the first duct or the second duct, a conduit connecting the circulating condensate inlet of the container and the bottom of the cooler, and a pump attached to the conduit. Fixation processing equipment for liquid organic halides. 3. The device according to claim 2, wherein a gas adsorption treatment device is disposed in the first duct or the second duct via a pressure regulating valve.
