Liquid chlorine directly charging system and apparatus

Abstract

The invention discloses a liquid chlorine directly charging system and apparatus comprising an online liquid chlorine cylinder, characterized in that, the online liquid chlorine cylinder is connected with the liquid chlorine deposition cylinder, liquid chlorine deposition cylinder is connected to a metering pump, the metering pump is connected with a liquid chlorine feeding device. The apparatus can be applied for improving the drinking water quality.

Description

technical field [0001] The invention relates to a tap water disinfectant (liquid chlorine) dosing process system, in particular to a liquid chlorine direct dosing process system and device. Background technique [0002] In 1835, Dr. Robley Dunglinson published a paper on "Human Health" in Philadelphia, USA, and proposed the use of chlorine to disinfect drinking water. [0003] In 1850 Dr. John Snow used chlorine to disinfect drinking water following a cholera outbreak in London, England. In 1897 Sims Woodhead used a bleach solution (the active ingredient was chlorine) as a temporary measure to disinfect water mains following a typhoid outbreak in Kent, England. In 1902, Middlekerke in Belgium established the world's first permanent water plant for disinfection with chlorine. In 1912, the Niagara Falls Water Plant in the United States used liquid chlorine to disinfect tap water, and adopted the chlorine injection equipment developed by Dr. Georg Ornstein.

AI Technical Summary

Problems solved by technology

[0015] 4. At present, the flow section of the throttle valve of the chlorinator is not large, so the flow fluid should not entrain solid particle impurities, otherwise the throttle valve may be blocked

[0021] 2. Large investment: a water supply of 300,000 m 3 Take a medium-sized water plant per day as an example, the total investment in the current chlorination system is about 1.5 million yuan (unit price of main equipment: 200,000 yuan / set for electric evaporator, 150,000 yuan / set for automatic chlorination machine, 4,000 yuan for liquid chlorine cylinder / indivual);

[0022] 3. High operating cost: Due to the large investment, the overhaul cost and depreciation cost are also high

[0023] High electricity consumption (about 30,000 yuan / year)

[0024] 4. The system equipment is complex and difficult to control, which is not conducive to the automatic operation of the water plant
