<p><P>PROBLEM TO BE SOLVED: To provide a system for converting a waste liquid containing harmful chemical substances, such as chlorine hydrocarbons, into a waste liquid satisfying a cost, a treatment capacity, safety, etc. <P>SOLUTION: The waste liquid treatment system comprise a heat insulating storage tank part 1 capable of keeping the waste liquid W warm and storing it, an atomizing chamber part 2 capable of gasifying the waste liquid by atomization and/or heat evaporation, a heating and decomposing chamber part 3 of which the inside temperature is kept at thermal decomposition temperature enabling the thermal decomposition of harmful chemical substances contained in mist of the waste liquid and/or in vapor gas G when the mist of the waste liquid and/or the vapor gas from the atomizing chamber part pass through the inside of the heating and decomposing chamber part 3, a quick cooling part 4 cooling decomposed exhaust gas quickly, and a vacuum pump part 6 capable of sucking the exhaust gas into the quick cooling part. The atomized and/or gasified vapor gas is thermally decomposed in the heating and decomposing chamber part. The inside of the heating and decomposing chamber part is maintained in a practically oxygen-free and reduced pressure atmosphere, and the inside temperature is kept at the thermal decomposition temperature enabling the thermal decomposition of the harmful chemical substances, which enables the thermal decomposition of the waste liquid at lower temperature than a temperature in the atmospheric pressure. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
