专利汇可以提供Ozone removing equipment专利检索,专利查询,专利分析的服务。并且PURPOSE: To make replenishment of water and alkali solution to the alkali washing tower unnecessary, by reducing the chemical oxygen demand of thiosulfate washing tower through utilizing washing water for alkaline thiosulfate washing tower of a ozone removing equipment to the replenishing water of alkali washing tower.
CONSTITUTION: Gas from which ozone is removed is treated by showering in an alkali washing tower 1. Then, it is treated by showering in an alkaline thiosulfate washing tower and the gas to be treated is washed and discharged. At this time, a part of washing water is sent to the washing tower 1 by a definite quantity by a pump 7 to substitute the replenishing water for washing and replenishing water for alkali washing tower. Consequently, the replenishment of water and alkali solution can be eliminated, and oxidation efficiency of alkaline thiosulfate in the second stage washing water can be increased. Further, oxidation for waste solution processing is made unnecessary and it can be discharged after neutralization only.
