Description

The dry-cleaning method of a kind of family expenses dry cleaner and clothing
Technical field
The present invention relates to the dry cleaner field, the dry-cleaning method of particularly a kind of family expenses dry cleaner and clothing.
Background technology
The dry-cleaning industry has experienced the blank phase of previous decades in China; To today in the real development of China also with regard to the history of more than ten years, but go back imperfection comparatively speaking, make a general survey of the dry-cleaning development history of All Around The World; It is as the part of people's house life; The one section marvellous road of having passed by, card West Asia dry-cleaning operation for many years can find out that the dry-cleaning industry is desired in the whole world especially to show a dry-cleaning heat in China.Along with the significantly raising of the Chinese level of consumption, each ages are also increasingly high to the requirement of dry-cleaning, and people have regarded dry-cleaning as the part of life.
Existing dry cleaner is made up of liquid reserve tank, washing chamber, washing agent retracting device, filter, condenser, distiller, separator, steam generator, pump, blower fan and electric box; Described liquid reserve tank generally is made up of 3 casings, respectively as dirty case, raising middle flask and knock-out.Clothing is isolated dirt after soaking into, roll, rubbing in the washing chamber of injecting cleaning solution, reaches the purpose of cleaning, and cylinder rotates at a high speed in the washing chamber then, and the cleaning solution brute force that clothing absorbs is taken off agent, and the soiling solution of discharge is put into dirty case behind filter.Clothing starts blower fan, steam generator when oven dry, because fan action forms circulating current in washing chamber, filter, retracting device scope, circulating current constantly gets into the washing chamber through the heating of steam heating chamber, and clothing is dried.The washing agent volatilization gas that produces through heating back in the washing chamber is pumped to and is condensed into liquid in the condenser and after separator dewaters, enters in the knock-out.Soiling solution in the dirty case can be recycled, and its method is with pump soiling solution to be evacuated in the distiller, and the steam that steam generator produces is to the heating of distiller stack shell, makes washing agent evaporation back in the soiling solution get into condenser and is cooled to clear liquid and puts into knock-out.So that continue to use in the next cleaning frequency.
The following scheme of the general employing of existing dry-cleaning method:
1, adopt distillating method to reclaim solvent: at present, all tetrachloro-ethylenes and hydrocarbon solvent, and other dicyandiamide solutions; All be to adopt the distillation recovery method that the waste liquid solvent is distilled recovery; Thereby the realization cycling and reutilization, the method needs distilling apparatus, has the solvent of lightning to need decompression distillation to hydrocarbon type; Increase vacuum pump apparatus, complex structure and volume are bigger.
2, adopt recovered under reduced pressure: this method is only applicable to carbon dioxide solvent dry-cleaning system: reduce the solvent in-cylinder pressure, liquid CO 2 becomes gaseous state by liquid state, realizes the solvent recovery cycle utilization.During solvent recovery; As long as the pressure in the solvent cylinder is laid down, liquid CO 2 is gasificated into normality gas CO2 naturally, thereby realizes the recovery of solvent; Owing to need very high pressure in the washing process with carbon dioxide gaseous state boil down to liquid; Higher to equipment requirements, need high-pressure installation, machine is huge and have a potential safety hazard.
To first kind of scheme, now the dry cleaner's naphtha on the market generally divides two kinds of tetrachloro-ethylene lotion and oil lotions, and the price of per kilogram is about 16 yuan, far above the water price with ton calculating.Dry cleaner's naphtha after the use need just can revert to limpid through the distil(l) processing, and reuses, but the distil(l) process of dry cleaner's naphtha generally needs 48 hours, and consuming time, power consumption also consumes oil, becomes one of prime cost of drycleaner's.Just therefore,, many drycleaner's do not do distil(l) after dry cleaner's naphtha uses and handle in order to practice thrift cost, directly get into next time and dry-clean, Cai distil(l) is once when treating that dry cleaner's naphtha can't use really.
The same with water in fact, the dry-cleaning oil wash clothes will be dirty, should purify the back and reclaim use, preferably wash and once just distill cleaning.
After client's clothes was taken drycleaner's, drycleaner's can be divided into dark color, light color and muted color branch according to color and come and wash, and " cauldron shuffles " then, clothes that maybe each client is not washed separately.Clothes after " long-used soup dry-cleaning ", through looking very neat clean after flatiron, the arrangement, but some dirty dust, that greasy dirt has been hidden in garment fabric is inner, adds that cauldron shuffles, extremely unhygienic.
In sum, because existing dry-cleaning equipment structural level system complex, and have various drawbacks, and like needs solvent is distilled recovery etc., be difficult to be applicable to problems such as family or the amateur user of drycleaner's dry-clean.Therefore a kind of small-sized dry cleaner and a kind of good washing effect of family expenses are provided, and the energy-conservation dry-cleaning method of economizing consumption again has great positive effect.China application CN99808589.8 discloses a kind of new dry cleaning system and method, and above-mentioned application adopts improved dry cleaner to be used in combination with special solvent, and described solvent comes from a kind of hybrid thing (organosiloxane).In this type of organosiloxane, there is one group to be known as annular siloxane.The dry-cleaning flow process comprises the steps: clothing is positioned over buck basket; Washings is soaked in the silicone components, the agitator treating thing; Remove most silicone components; The centrifuge dripping washings; Washings is imposed negative pressure, heat up; Behind cooling and the recovery normal pressure, washings is taken out from buck basket.Though above-mentioned dry-cleaning method has improved the dry-cleaning quality to a certain extent, above-mentioned dry cleaning agent is undesirable to the removal effect of water-soluble spot, and its to clothing to protect chromatic effect not remarkable yet.Therefore, still treat in existing dry-cleaning method is done further to improve.
In view of this, special proposition the present invention.

Do further to introduce in detail below in conjunction with 1,2 pairs of dry cleaners provided by the invention of accompanying drawing and dry-cleaning method.
One skilled in the art will appreciate that the above dry cleaner of 9 feather weight all can have two or three dry cleaning agent fluid reservoirs, during use; The dry cleaning agent of having dry-cleaned dirty linen each time is collected in the waste liquid tank, after water-separator is handled, waste liquid is distilled processing through the distillation recovery system; And the dry cleaning agent after will reclaiming is collected in the dry cleaning agent fluid reservoir and supplies dry-cleaning next time, and therefore, conventional washing machine has huge volume and complicated structure; Running and maintenance are also quite loaded down with trivial details; Cost is high, owing to adopt the operating mode of " long-used soup dry-cleaning " in the drycleaner's mostly, there is serious health concerns in the clothing after the dry-cleaning.In view of this, but the inventor is devoted to study a kind of dry cleaner of small-sized family expenses, and the user promptly can dry-clean the clothing of oneself at home, convenient health again.The large-scale dry cleaner that tradition is used is transformed into the family expenses dry cleaner big or small with common washing roller washing machine, at first must simplify its structure.Adopt perchloroethylene or liquid carbon dioxide or other to commonly use dry cleaning agent and all be difficult to further simplify again the dry cleaner structure; Therefore; The inventor adopts a kind of moisture ethers dry cleaning agent to replace conventional dry cleaning agent, and has proposed a kind of family expenses dry cleaner easy to use simple in structure to this moisture ethers dry cleaning agent.
The present invention requires the family expenses dry cleaner protected; The port of export of dry cleaning agent fluid reservoir links to each other with the inlet of circulating pump with the dry-cleaning cylinder through pipeline, electromagnetic valve successively, and the leakage fluid dram of dry-cleaning cylinder links to each other with the entrance point of dry cleaning agent fluid reservoir through pipeline and electromagnetic valve and forms a circulation canal; Described heater one end links to each other with fan through the air channel, and the other end connects the air inlet of dry-cleaning cylinder, and stram condenser one end connects the air outlet of dry-cleaning cylinder, and the other end links to each other with the dry cleaning agent fluid reservoir with electromagnetic valve through pipeline.
For reduced volume and reduction production and use cost, the distillation recovery system of dry cleaning agent is not set in the family expenses dry cleaner of the present invention.Because dry cleaner of the present invention is the user who is applicable to family or amateur dry-cleaning, and is therefore, low than large-scale dry cleaner to the requirement of dry cleaning agent and dry-cleaning equipment.In addition; Because the present invention has adopted unique dry cleaning agent; This dry cleaning agent not only cleaning strength is high, and stability is high simultaneously, therefore need not in dry cleaner, to be provided with the distillation recovery system of dry cleaning agent; Also need not to be provided with filter, through drying and drying course dry cleaning agent recycled after dry-clean clothing at every turn.Family's operating position by common infers that dry cleaning agent can recycle (half a year approximately) more than 50 times, and the user will use dry cleaning agent repeatedly directly to emit the additional new dry cleaning agent in back according to actual conditions and get final product.With each dry-cleaning end back dry cleaning agent is distilled purification and compare, adopt dry cleaner of the present invention and dry-cleaning method, the same terms can reduce 2-3 cost doubly down.Because dry cleaner has reduced the treatment system (comprise filtration system and distillation recovery system) of solvent, therefore, has dwindled the volume of dry cleaner greatly, this microminiature family expenses dry cleaner be prior art can't realize.
As another embodiment of the invention, can in dry cleaner, add filter, utilize filter to come dry cleaning agent is carried out filtration treatment, to realize the recycle of dry cleaning agent better.Described filter can be located between circulating pump and the dry-cleaning cylinder inlet or be located between the leakage fluid dram and dry cleaning agent fluid reservoir entrance point of dry-cleaning cylinder.Dry cleaner of the present invention can adopt the disclosed filter of prior art, but through the big quantity research that the inventor carries out structure of filter, has proposed a kind of composite type filter (see figure 2) of the present invention that preferably is applicable to.Described filter has the composite construction more than two-layer the reaching that comprises coarse filtration layer-charcoal absorption filter course.Filter is the core adsorbing medium with the active carbon, and coarse filtration mainly focuses on millimetre-sized solids such as collecting fine hair, line bits, and the size of the filter screen of coarse filtration layer is more than 250 orders; Active carbon filter mainly adsorbs the micron order bacterium and is dissolved in the free state spot in the dry cleaning agent.In addition, filter can also be arranged to the composite structure of three layers or four layers, and the filter course that on the basis of coarse filtration layer-charcoal absorption filter course, adds other is to realize better filter effect.
In addition; In research process, find; The effect that ozone generating-device or negative ion generating device not only can play sterilizing is set on dry cleaner, can also effectively promotes the dissolving of dirt in dry cleaning agent simultaneously, alleviate the present invention and only depend on filter to realize the pressure of dry cleaning agent recycle.Therefore, the present invention is in the circulation air path system that also is provided with ozone generating-device or negative ion generating device on the dry cleaner and makes the recycle in dry cleaner of ozone and anion.This concrete set-up mode is grasped by ability preforming technique personnel.
The present invention also provides a kind of dry-cleaning method, and this invention can be adopted dry cleaner of the present invention but be not limited in said structure.Those skilled in the art can select can use in the prior art dry cleaner of dry cleaning agent of the present invention to realize that the present invention requires the dry-cleaning method of protecting.
The dry-cleaning method of clothing of the present invention specifically comprises the steps:
(1) feed liquor and washing: clothing that will be to be dry-cleaned is put into the dry-cleaning cylinder; With dry cleaning agent from the dry cleaning agent holding vessel pump to dry-cleaning cylinder; In the dry-cleaning cylinder, stir clothing, accomplish the washing of clothing;
