Full-automatic high concentration sodium hypochlorite generating system

Abstract

The invention provides a full-automatic high concentration sodium hypochlorite generating system, comprising a water purifying unit, a salt dissolving unit, an electrolytic unit, an acid pickling unit, an alkali dissolving unit, a cooling unit, an absorption unit and a feeding unit, wherein the water purifying unit is connected with the salt dissolving unit, the electrolytic unit, the acid pickling unit and the alkali dissolving unit; the electrolytic unit is connected with the salt dissolving unit, the acid pickling unit, the alkali dissolving unit, the cooling unit and the absorption unit; the absorption unit is connected with the cooling unit; the water purifying unit, the salt dissolving unit, the electrolytic unit, the acid pickling unit, the alkali dissolving unit, the cooling unit,the absorption unit and the feeding unit are controlled by means of a programmable logic controller (PLC) unit so as to automatically execute actions of water replenishing, salt dissolving, washing, acid pickling, circulating, electrolyzing and discharging. The full-automatic high concentration sodium hypochlorite generating system can realize full automatic production of a sodium hypochlorite solution under the control of a PLC.

Description

technical field [0001] The invention belongs to the technical field of drinking water disinfection, and in particular relates to a fully automatic high-concentration sodium hypochlorite generating system. Background technique [0002] The use of sodium hypochlorite solution for disinfection is a relatively safe disinfection method. Although the water plant can purchase commercial sodium hypochlorite solution for disinfection, the use of commercial sodium hypochlorite solution for disinfection has high cost and high pH value, and it is easy to block and corrode when adding. There are problems such as adding pumps, and it is inconvenient for water plants in some areas to purchase sodium hypochlorite solution, and the number and level of operation and management personnel are limited. Therefore, it is necessary to develop a sodium hypochlorite solution generating device capable of fully automatic control, which is easy to operate and easy to maintain. Contents of the inventio...
