Multi-standard type ion-exchanger

Abstract

The invention relates to a multi-system ion exchanger, which comprises heat exchangers A and B, wherein a suction pipe (24) and a down-flow pipe (25) are respectively arranged in the upper parts and the lower parts of the heat exchangers A and B, pipes (a, b, c, d, e, f, g) are sequentially connected between the suction pipe (24) and the down-flow pipe (25), valves (18, 5, 1, 2, 6, 20) are respectively arranged in the upper parts of the pipes (a, b, c, d, e, f, g), and valves (21, 7, 3, 4, 8, 19) are respectively arranged in the lower parts of the pipes (a, b, c, d, e, f, g); valves (9, 10) are arranged in the suction pipe (24), and valves (11, 12) are arranged in the down-flow pipe (25); a valve (13) is arranged in the lower part of the pipe (d), and a soft water outlet port is arranged at the lower end of the pipe (d); a salt liquid injection pipe is connected between the pipe (c) and the pipe (e); a backwashing regeneration and direct washing water outlet port is arranged at the lower end of the valve (14); and a salt liquid recover port is arranged at one end of the valve (15).

Description

【Technical field】 [0001] The invention relates to an ion-exchange water treatment device, in particular to a multi-system ion exchanger which is composed of multiple valves and is connected in series and in parallel with dual-flow pipelines and can effectively soften water quality. 【Background technique】 [0002] At present, the boiler water treatment exchangers used in the market, after being used for a certain period of time, there will be impurities such as suspended solids and damaged resin, calcium and magnesium ions in the exchangers. If they cannot be completely regenerated, it will directly affect The water quality and water production volume of positive washing and exchange water production. There are many reasons that affect regeneration. In addition to resin aging and contamination by active residual chlorine, iron, and aluminum ions, it is also related to water temperature, salt solution concentration, flow rate, regeneration time, regeneration method, and salt p...

Problems solved by technology

[0002] At present, the boiler water treatment exchangers used in the market, after being used for a certain period of time, there will be impurities such as suspended solids and damaged resin, calcium and magnesium ions in the exchangers. If they cannot be completely regenerated, it will directly affect The water quality and water production volume of positive washing and exchange water production

There are many reasons that affect regeneration. In addition to resin aging and contamination by active residual chlorine, iron, and aluminum ions, it is also related to water temperature, salt solution concentration, flow rate, regeneration time, regeneration method, and salt purity. Both have the disadvantages of high salt consumption, large discharge, and poor backwashing, regeneration and replacement effects
