Boiler make-up water purification system

Abstract

The invention discloses a boiler make-up water purification system. The system includes a multimedium filter, a heat exchanger, a security filter, a high pressure pump, a reverse osmosis system, a carbon, carbon remover, a water tank arranged on the lower part of the carbon remover, a mixed bed water conveying pump, an ion exchange mixed bed, a particle filter, a desalination water tank and a desalination water pump; and the system also includes a dosing system arranged between the heat exchanger and the security filter and an ammonia addition system set up at the water outlet end of the desalination water pump. According to the boiler make-up water purification system of the invention, the multimedium filter uses quartz sand and active carbon to remove impurities of colloid, mud and suspended solids in tap water; the reverse osmosis system can remove 99.9% of organic matters and bacteria and 98% of salts in the water; and the ion exchange mixed bed exchanges the ion state substances in water to obtain high purity deionized water, so as to ensure the long term operation of the boiler without scaling.

Description

technical field [0001] The invention relates to water treatment equipment, in particular to a boiler feed water purification 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 feed water purification system to obtain high-purity deionized water, avoid scaling of the boiler, and ensure long-term stable performance of the boiler. [0004] The boiler feed water purification 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-pressure pump, a reverse osmosis system,...
