Description
Technical field
The present invention relates to a kind of purifier, specifically is the purifier of heavy metal in a kind of 13x of use molecular sieve purification tap water.This device uses the molecular sieve filled filter core of 13x, can the deep purifying tap water.
Background technology
Along with developing rapidly of industry and agricultural, many water resourcess of China have received comparatively serious pollution.Increasing industrial wastewater discharge has polluted the water source in rivers, lake, destroyed our ecotope.Wherein the harm that causes of heavy metal contamination is huge, and has a far reaching influence.As: contain toxic very big cadmium ion (Cd in the waste water of dischargings such as plating, mining, smelting, fuel, battery and chemical industry
2+), it can replace calcium in the bone, makes bone seriously softening, causes itai-itai disease, also can cause the dirty functional disorder of stomach, causes vascular hypertension.Automobile exhaust gas and Industrial emissions contain deleterious lead ion (Pb
2+), family's Corrosion of Pipeline also causes the tap water lead tolerance to increase easily, and in a single day it get into human body and will be difficult to get rid of; Directly the neural system of the brain cell, particularly fetus of harm people can cause congenital mental retardation; Clinical manifestation is anaemia, peripheral neuritis, motion and paresthesia occur.In addition, cosmetic material, leather preparation, metal parts chromium plating part, industrial pigment and tanning, rubber and Ceramic Material etc. can cause chromium ion (Cr
6+) pollute, the excessive absorption of chromium can cause toxicity symptoms such as abdominal discomfort and diarrhoea, causes allergic dermatitis or eczema, breathes to get into, and respiratory tract is had to stimulate and corrosive nature, causes pharyngitis, bronchitis etc.In a word, these heavy metals healthy to the seriously polluted ground affect people's of tap water.
At present, dispose of sewage in the industry in the method for heavy metal mainly remove the heavy metal contamination in the waste water through chemical precipitation method and ion exchange method.But, adopt the emission standard of this technology WWT all to be difficult to reach, and running cost is very high.As adopt chemical precipitation method to handle as the one-level of heavy metal-containing waste water, and remove most of heavy metal ion, adopt flocculation sediment and filtration method that heavy metal-containing waste water is carried out the secondary advanced treatment.This method complex process, processing cost is high, and treatment effect is not ideal enough, also is not suitable for the processing of the removing heavy metals of tap water.
The 13X molecular sieve is a kind of silico-aluminate compound with cubic(al)grating, and it has uniform microvoid structure, and its hole diameter is even; The molecular adsorption littler than its diameter can be arrived the inside of vestibule in these holes, and polar molecule and unsaturated molecule are had the preferentially adsorbed ability, thereby can be different polarity degree; Degree of saturation is different; The different molsep of molecular size difference and boiling point comes, and promptly has the effect of " screening " molecule, so claim molecular sieve.Because molecular sieve has the adsorptive power height, thermostability waits the unexistent advantage of other sorbent material by force, makes that molecular sieve obtains to use widely.At present, molecular sieve is at metallurgy, chemical industry, and electronics, petrochemical complex is in the industry such as Sweet natural gas, particularly in the gas industry widespread use.Chinese patent 02137109.1 discloses the method that a kind of 13X of utilization molecular sieve is handled nitrogenous ammonia waste water.Therefore the technology of utilizing in the 13X molecular sieve treating water heavy metal in the tap water particularly also seldom, is starved of and proposes a kind ofly with heavy metal in the 13X molecular sieve purification tap water, and tap water is carried out the deep purifying Treatment Technology.
Summary of the invention
The present invention provides the 13x molecular sieve water purifying device of heavy metal in a kind of purifying drinking water in order to solve the problems of the technologies described above, and this apparatus structure is reasonable, and method is simple to operate, and it is big to handle the water yield, and cost is low, and purifying water effect is very good.
The objective of the invention is to realize through following technical scheme: the 13x molecular sieve water purifying device of heavy metal in the purifying drinking water, be provided with at least one filter cylinder, each filter cylinder is provided with the filter cylinder shell; Be provided with a filter core in each filter cylinder shell, be provided with water-in and water outlet, said water-in and water outlet are communicated with filter core; It is characterized in that said filter core is processed with stainless (steel) wire, its shape such as tubular; Volume is slightly less than the filter cylinder shell; The 13x sieve particle is housed in this filter core, and this particulate diameter is 1～10mm, and its weight is pressed the volume calculation of filter core: every cubic centimetre 0.5～5 gram.
Said filter cylinder is provided with 2-5, and the entery and delivery port of filter cylinder is chained together each other, and promptly the water outlet of previous filter cylinder is communicated with the water-in of a back filter cylinder.
The water-in of said filter cylinder is provided with flowrate control valve.
Said flowrate control valve is an automatically controlled valve, each automatically controlled valve and the control linkage that unit carries out flow control.
Be provided with flow indicator and clean the said filter core and the acousto-optic warning device of renew cartridge more, this flow indicator and acousto-optic attention device and said unit carry out control linkage.
Filter cylinder front end at said filtering heavy metal also is provided with preposition filter cylinder; This preposition filter cylinder is provided with the filter core of silt in the filtering tap water, dirt, peculiar smell; This preposition filter cylinder is provided with water-in and water outlet, and is connected in series connection through water outlet with the filter cylinder of said filtering heavy metal.
The 13X molecular sieve specific surface that uses in the cleaning device of the present invention is big, has good absorption property, and molecular formula is: Na

2+Deng.Some researchs simultaneously show, when handling micro-polluted water such as leaded, cadmium, mercury with the 13X molecular sieve, go out water concentration, treatment time treatment capacity and adsorptive capacity aspect, basic because other the scavenging material of effect, efficient height.
Why the 13X molecular sieve can effectively remove the heavy metal ion in the tap water, and basic reason is that it has special vigilant mechanism, and the 13X molecular sieve has very big specific surface area; A large amount of heavy metal ion can be adsorbed in the surface; Especially the part tetravalence is kneeled to trivalent silicon and is replaced among its crystal result, and the load that arrives is superfluous, therefore; In structure, have monovalence or and valency positively charged ion such as sodium potassium calcium etc. the compensation excess charges; In the macroscopic void (0.9nm) of these positively charged ions existence and molecular sieve, can carry out permutoid reaction, cause the 13X molecular sieve to have big exchange capacity with other ion.When molecular sieve contacts with heavy metal ion, these positively charged ions of molecular sieve hole just with heavy metal ion generation IX.The 13X molecular sieve that has adsorbed heavy metal is advantages such as good inorganic antiseptic, safety, wide spectrum, non-secondary pollution environment.The 13X molecular sieve also has certain effect at aspects such as absorption ammonia nitrogen, hardness.Scavenging material 13x sieve particle provided by the invention not only can be removed other objectionable impurities in the water, improves water quality, and the water source that is particularly useful for containing the little pollution of heavy metal plays good decontamination effect improving, effectively improves the water quality of this area.
Purifier of the present invention has novel structure, and is simple and practical, the heavy metal in the filtering tap water, and deep purifying tap water effective, cost is low, advantage easy to use.
