Abstract

A deionizing water machine for a laboratory comprises a machine body, a water inlet (1), a pure water outlet (10) and a concentrated water drain hole (7), wherein the water inlet (1) is connected with a PPF (power factor indicator) filter (2) which is connected with an active carbon filter (3); the active carbon filter (3) is connected with an active carbon rod filter (4); the active carbon rod filter (4) is connected with a water inlet of a high pressure pump (5); a water outlet of the high pressure pump (5) is connected with an RO (reverse osmosis) device (6) which is connected with a polishing mixed bed (9); the polishing mixed bed (9) is connected with the pure water outlet (10); the concentrated water outlet of the RO device is connected with the concentrated water drain hole (7); an RO member is arranged in the RO device (6); and polishing resin is arranged in the polishing mixed bed (9). The deionizing water machine uses the polishing resin which does not need to be regenerated, can ensure the outlet water quality, cannot affect the environment and is particularly suitable for the laboratory.

Description

Laboratory deionized water machine

[technical field]

The utility model relates to the processing of water, waste water or sewage that ion exchange method carries out, relates to the device that separates or remove grease or oily mater or similar seston, refers to a kind of laboratory deionized water machine especially.

[background technology]

In the prior art, deionized water equipment, by cationic exchange coloum, anion-exchange column. the hybrid ionic exchange column is equipped with some valves and pipe arrangement is formed, this deionized water equipment need make spent ion exchange resin, to consume a large amount of soda acids and adopt common ion exchange method to prepare pure water, soda acid is being produced, transportation, in storage and the use, bring inevitably to the pollution of environment with to the corrosion of equipment, high to possible injury of human body and maintenance cost, effluent quality is also unstable, especially is not suitable for the preparation of deionized water in a small amount in the laboratory.

[summary of the invention]

At the defective of prior art, the purpose of this utility model is to provide a kind of use to need not regenerated polishing resin, can guarantee effluent quality, again the deionized water machine that is specially adapted to the little consumption in laboratory that can not impact environment.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of laboratory deionized water machine, comprise body, water-in, pure water outlet and concentrated water discharge mouth, and it is characterized in that; Also include the PPF strainer in the body, activated charcoal filter, the active carbon stick strainer, high-pressure pump, RO counter-osmosis device and polishing mix bed, water-in is connected with the PPF strainer, the PPF strainer is connected with activated charcoal filter, activated charcoal filter is connected with the active carbon stick strainer, the active carbon stick strainer is connected with the water-in of high-pressure pump, the water outlet of high-pressure pump is connected with the RO counter-osmosis device, the RO counter-osmosis device mixes bed with polishing and is connected, polishing mixes bed and is connected with the pure water outlet, the dense water out of RO counter-osmosis device is connected with the concentrated water discharge mouth, the RO membrane module is housed in the RO counter-osmosis device, and polishing mixes in the bed polishing resin is housed.Various controls, bypass or maintenance valve can be installed between each device as one sees fit.

In the utility model, the PPF strainer mainly is the iron rust of removing in the water, silt, suspended substance and red worm; Activated charcoal filter mainly is heterochromatic, the peculiar smell of removing in the water of part; The effect of high-pressure pump is that Jiang Yuanshui is delivered to the RO counter-osmosis device, enters the polishing mixed-bed system then; The effect of the mixed bed of polishing is the positive and negative ion in the filtered water.

It is exactly ion exchange method in fact that polishing mixes bed desalination method, and it is to utilize hydrogen type cation exchange resin with the various positively charged ion generation permutoid reactions in the water, with all positively charged ions in the former water of exchange removal; Utilize hydrogen-oxygen type anionite-exchange resin to remove all negatively charged ion in the former water with exchange with the various anionic reactives in the water.And only have the H that can be combined into water after the generation permutoid reaction in the water ⁺Ion and OH ^-Ion, thus reach the purpose of desalination.The mixed bed of polishing is mixed into the polishing resin by a certain percentage with two kinds of ion exchange resin of special positive and negative and fills in the exchange bed, in the exchange bed, because anion and cation exchange resin is placed in the same interchanger and is mixed uniformly, when ion-exchange moves, permutoid reaction almost takes place in yin, yang ion in the water simultaneously, through the H of Hydrogen sun resins exchange reaction generation ⁺With the OH that generates through hydrogen-oxygen type negative resin permutoid reaction ^-, in mixed ion exchanger, obtain neutralization immediately and generate water, there is not the interference of gegenion, therefore, ion exchange reaction is carried out very thoroughly, and its effluent quality purity is very high.

The beneficial effects of the utility model are: use to need not regenerated polishing resin, can guarantee effluent quality, can the deionized water that is specially adapted to the little consumption in laboratory that environment impacts not prepared again.
