Boiler filtering deionized water processing system

Abstract

The invention discloses a boiler filtering deionized water processing system. The boiler filtering deionized water processing system comprises a multi-media filter, a heat exchanger, a precision filter, a high pressure pump, and a reverse osmosis system, and also comprises a chemical dosing system arranged between the heat exchanger and the precision filter; the chemical dosing system comprises a scale inhibitor adding system and a NaHSO4 adding system. According to the multi-media filter, filter layers composed of quartz sand and active carbon at a certain ratio are used for removing impurities such as suspensions, sludge, and colloids in tap water completely; the chemical dosing system is used for adding sodium hydrogen sulfite into water so as to avoid oxidation damage of reverse osmosis membrane; a scale inhibitor is added into water so as to avoid crystallization separation of salts in concentrated water in the reverse osmosis system and protect characteristics of the reverse osmosis membrane; and the reverse osmosis system can be used for removing 99.9% of organic matters and bacteria, and 98% of salts in water, improving water quality greatly, and ensuring long-term operation of boilers without generation of scale.

Description

technical field [0001] The invention relates to water treatment equipment, in particular to a boiler filtering deionized water treatment system. Background technique [0002] The make-up water for the boiler needs to be strictly treated, otherwise the boiler will easily scale and reduce the heat utilization rate; the ion content in the water treated by the water treatment equipment in the prior art is still high, so that the boiler will still appear in the long-term operation. Dirt and other issues. Contents of the invention [0003] In view of this, the object of the present invention is to provide a boiler filter deionized water treatment system to obtain high-purity deionized water, so as to avoid the impact of ionic substances on the long-term stable operation of the boiler. [0004] The boiler filter deionized water treatment system of the present invention comprises a raw water tank, a raw water pump, a multi-media filter, a heat exchanger, a security filter, a high...
