The negative pressure type chlorination machine structure JLF-B type chlorination machine is characterized by effectively eliminating the chlorine leakage accident, ensuring personal safety, and adding an automatic retaining residual pressure device and filter in the pressure reducing valve, which can better In order to adapt to the domestic liquid chlorine impurities, do not use copper pipe to connect the pressure chlorine gas bottle, just connect the pressure reducing valve directly to the chlorine gas cylinder angle valve to operate normally and stably. Application of JLF-B negative pressure chlorination machine in our factory In August 2000, the factory installed one JLF-B2-6 type (the amount of chlorine added was 6kg/h) in Zhouyu Water Plant and 830 Water Plant respectively. And JLF-B2-4 type (4kg/h chlorination) chlorinator, after nearly 5 years of operation, the equipment not only has good safety performance, accurate chlorine control, but also easy to install and operate, reducing the operator's Labor intensity, to achieve the desired results. The water quality has been significantly improved. Before the renovation, the water quality of the two water plants is unstable due to the difficulty in controlling the amount of chlorine added. It is difficult to meet the national drinking water standards. After using the JLF-B type negative pressure chlorinator, the water quality has been significantly improved, and all the indicators have reached the national drinking water hygiene standards. The amount of chlorine consumed is greatly reduced. Before the renovation, the amount of chlorine used is large due to frequent chlorine leakage. For example: Zhouyu Water Plant, daily water supply is 36000, t chlorine consumption is 56kg; 830 water plant, daily water supply is 20,000, t chlorine consumption is 31kg. After the transformation, the daily water supply of the two water plants is unchanged, the amount of chlorine used The 41kg and 23kg respectively, the monthly saving of chlorine gas is 450kg and 240kg, respectively, and the monthly saving cost is 2070 yuan, which reduces the water treatment cost. Concluding remarks, although the investment is not much (about 20,000 yuan, the price of the chlorinator is only half of that of similar foreign products), but the effect is very obvious. After the water treatment, all the indicators have reached the national drinking water standard. The company's family of hundreds of thousands of employees on the mountain drank the water, the life safety of the operators was effectively guaranteed, and good social and economic benefits were achieved.
