〔産業上の利用分野〕
本発明は、気化物質の回収装置における気化物質の凍結
降下方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for freezing down a vaporized substance in a vaporized substance recovery device.
従来の技術には溶融亜鉛めっきのドロス活用法が行なわ
れていた。Conventional technology involves utilizing dross from hot-dip galvanizing.
気化物質を大気中に拡散した状態で回収すると気化物質
の存在する範囲が広い場合や拡散が速い場合は、回収装
置の大型化や回収効率の低下に問題があった。If vaporized substances are recovered in a state in which they are diffused in the atmosphere, if the vaporized substances exist in a wide area or if they diffuse quickly, there is a problem in that the recovery device becomes larger and the recovery efficiency decreases.
本発明の目的は、気化物質及び吸着した水分を瞬時に凍
結させ、気化物質の拡散を防止し、かつ、降下させるこ
とにより、回収装置の小型化及び回収効率を高め、かつ
、作業環境を改善することにある。The purpose of the present invention is to instantly freeze vaporized substances and adsorbed moisture, prevent the diffusion of vaporized substances, and lower the vaporized substances, thereby reducing the size of recovery equipment, increasing recovery efficiency, and improving the working environment. It's about doing.
上記目的を達成するために、本発明は気化物質及び気化
物質に吸着した水分に対して、気化物質の転移点以下の
温度の液体を放射する。To achieve the above object, the present invention irradiates a vaporized substance and moisture adsorbed on the vaporized substance with a liquid having a temperature below the transition point of the vaporized substance.
気化物質に対して気化物質の転移点以下の液体を放射す
ることにより、気化物質は瞬時に凍結・降下する。また
、気化物質に吸着した水分も同時に凍結させることによ
り、降下を促進させる。By emitting a liquid below the transition point of the vaporized substance to the vaporized substance, the vaporized substance instantly freezes and falls. In addition, the moisture adsorbed on the vaporized substance is also frozen at the same time, thereby accelerating its descent.
溶融亜鉛めっき処理の直後、めっき品に、受皿４上で、
塩化アンモニウムを噴霧させる。その際。Immediately after the hot-dip galvanizing process, the plated product is placed on the saucer 4,
Spray with ammonium chloride. that time.
塩化アンモニウム３が気化し、大気中に飛散する。Ammonium chloride 3 vaporizes and scatters into the atmosphere.
本発明によれば、大気中に飛散した塩化アンモニウム３
に対してノズル１より、液体窒素２を放射する。このと
き、塩化アルモニウム３の転移点は、−３０，５℃のた
め、温度−１９５，８℃の液体窒素２を放射することに
より、塩化アンモニウム３及び塩化アンモニウム３に吸
着した水分が凍結し、受皿４に降下するため、回収効率
が向上する。According to the present invention, ammonium chloride 3 scattered in the atmosphere
Liquid nitrogen 2 is emitted from a nozzle 1 toward the target. At this time, the transition point of aluminum chloride 3 is -30.5°C, so by radiating liquid nitrogen 2 at a temperature of -195.8°C, ammonium chloride 3 and the water adsorbed on ammonium chloride 3 are frozen. Since it descends into the saucer 4, the collection efficiency is improved.
本発明によれば、気化した塩化アンモニウムを凍結させ
、回収するので、環境改善の効果がある。According to the present invention, since vaporized ammonium chloride is frozen and recovered, there is an effect of environmental improvement.
また、回収した塩化アンモニウムを再利用することによ
り、材料費低減の効果がある。Furthermore, reusing the recovered ammonium chloride has the effect of reducing material costs.
