Description

SYSTEM AND METHOD FOR EXTRACTING WATER IN A DRY CLEANING PROCESS INVOLVING A SILICONE-BASED SOLVENT AND METHODS ENHANCING THE PROCESS OF CLEANING}

Dry cleaning is a major industry worldwide. There are more than 40,000 dry cleaners in most parts of the United States alone. The dry cleaning industry is indispensable in the current economic situation. Many types of clothing (and others) need to be dry-cleaned to remove grease or oil to prevent them from discoloring or shrinking.

Dry cleaning solvents that are widely used to date are perchlorethylene (PERC). However, there are many disadvantages of PERC due to remaining toxins and odors.

Another problem in this area is that different types of fibers must be handled differently to avoid damaging the fibers during dry cleaning in current systems.

Conventional dry cleaning processes involve the use of various solvents in a suitable machine for cleaning. As mentioned above, the commonly used solvent is PERC. PERC has the advantage of being a good cleaning solvent, but has disadvantages for health and the environment. It can cause cancer and cause serious contamination of groundwater or water. In the past, other solvents such as petroleum-based solvents and hydrocarbons were used. These various solvents are less dangerous than PERC, but are still classified as explosive organic compounds (VOC's). Such composites are licensed and controlled by the aeronautical authorities.

The dry cleaning industry has relied heavily on petroleum-based solvents, well-known chlorinated hydrocarbons, and perchlorethylene for cleaning textiles and clothing. Since 1940, PERC has been in the spotlight in the dry cleaning industry because it is a non-flammable, oil-free compound that can clean large amounts. In early 1970, it was found that PERC causes liver cancer in animals. It was a serious discovery that dry cleaning waste was dumped in landfills and collection sites and absorbed into soil and groundwater.

The Environmental Protection Agency's policy was gradually strengthened, and in 1996 a law came into force that all dry cleaners must include a "dry vs. dry" cycle, that is, fibers or clothes that went into the machine for dry cleaning must be dried out. The rule is at its peak. There was a need for a "closed loop" system that could regain almost all PERC liquids or vapors. This treatment "cycle" relates to a specially designed washing machine capable of storing 15 to 150 pounds of fibers and clothes as long as the clothes or fibers can be seen through the carousel. Before entering the machine, clothes or textiles are partly treated by hand for stains. If the fibers turn out to be special or unwieldy, they are labeled to ensure that the manufacturer is safe for dry cleaning. If not, the stain will not be removed and will remain. If the stain is fat-related, water will not help at all, but solvents will help because it dissolves fat. In fact, the main reason for dry cleaning certain clothes (which should not be washed in a regular washing machine) is to remove them because the body oil (known as fatty acid) produced is overly oxidized and smells bad.

Fats and fatty acids formed in the solvent are filtered off and the solvent is distilled off. In other words, the dirty solvent is boiled, and all the vapors are condensed through the condensation coil into a liquid. Residual NVRs (nonvolatile residues) are subsequently removed and disposed of according to regulations. The regenerated liquid consists of solvent and water, which is then passed through a separator to separate into two unmixed liquids. Water arises from the natural moisture of the ambient air exposed to the fibers before cleaning. Another source of moisture may be the material used in the precontamination process.

The washing machine becomes a dryer before the fibers are removed from the machine. Hot air is supplied through the compartment, but instead of being vented out, the air stream passes through a condenser that condenses the vapor into a liquid. The water must then be separated from the solvent and the solvent is reused.

If water is not separated from the solution, the water will enter the associated storage tank and, due to its density, will be at the bottom of the tank. If the water level is high enough, it will be pulled up by the pump system and pumped to damage the item being cleaned.

If the water remains in the base tank for a sufficient time, the bacteria will parasitic with a bad smell that will be transferred to the item being cleaned. Hydrocarbon solvents are a source of bacteria and allow bacteria to grow quickly. Silicone-based solvents do not generate bacteria, but the interface height between the lower density solvent and the denser water affects the water-solvent interface. Polar solvent dissolved contaminants at this interface height can include fatty acids, food, sweat, and general body odors. Remaining can cause the bacteria to grow quickly and cause odors.

Therefore, professional dry cleaning to control the water present is very important to avoid damaging the items being cleaned and causing odors that may be unsatisfactory to the customer.

It is important to note that many organic solvents vary with humidity. The organic solvent which is not normally soluble in water can be said to be hygroscopic because it can absorb moisture from the surrounding environment. In the case of circulating and linear silicone solvents, the absorbing water properties are shown (saturation point is about 200 per million units). This rate of water absorption increases when the solvent is heated to the moisture present. In dry cleaning applications, the garment is submerged in a silicone solution during the washing process and then centrifuged to remove residual solvent remaining in the garment. Heating evaporates the solvent and water. The solvent / water combination is sent to a cooling coil condenser where the final liquid solvent / water combination is a milky white form known as a colloidal emulsion or a liquid colloid. The milky white liquid is a silicone solvent that coexists with the absorbed molecular water. The water absorbed for a considerable time is gradually released by the solvent and separated into two given densities and weights. Absorption of water molecules in solvent molecules can weaken the van der Waals forces that hold them temporarily.

The two molecules that attract each other and the forces between them are called van der Waals forces in general terms. This arises from electrostatic forces between several charges in two molecules (constituent electrons and nuclear charges).

FIELD OF THE INVENTION The present invention relates to the general field of dry cleaning such as clothes, fabrics, fibers, and more particularly, to apparatus and methods for withdrawing water from dry cleaning solvents having a single density and specific weight properties. The apparatus and methods used to regenerate dry cleaning solvents and to improve decontamination while using silicon based solvents also change uniqueness.

An object of the present invention is to quickly and effectively break the molecular binding force of water and dry cleaning solvent so that the solvent and water can be separated quickly. The process of depriving water from hygroscopic solvents can be greatly influenced by the chemical properties and the design of the microcellular filter. The treatment of water decomposition from hygroscopic solvents can be greatly influenced by the chemical properties and the design of the micro cell permeable structure. This is true because as the water / solvent liquid mixture passes through the tiny orifices of the permeable structure, the force of attaching the water molecules to the solvent molecules diminishes, resulting in molecular separation.

Urea-formaldehyde bubbles having cell structures between 10 microns are a preferred material for forming permeable structures. As the solvent / water liquid passes through this hard but permeable medium, the solvent and water immediately separate due to a decrease in their density and adsorption force (van der Waals). Other factors that act as separations include capillary geometry, surface tension, and the difference in attraction between water and foam molecules versus silicon and foam molecules. These factors along the flow rate determine the separation rate.

Hard materials are preferred because they can withstand large pressure differentials. Certain flowable materials, such as open cell polyurethane foams and phenyl formaldehyde polymers, exhibit similar capabilities in separating solvent and water and can be used to form permeable structures. The pressure and cell size as the solvent / water liquid passes through the medium, and the density of the bubbles, determine the optimal degree of water association (decomposition) of water from the solvent. For example, a 3 inch diameter rigid bubble with a cell size of 10 microns is a successful water breakdown at flow rates above 3 GPM.

Various materials that can be used as the permeable structure will have different degrees of hydrophilicity (the ability to bond water). If the microcellular structure has a high level of hydrophilicity, the efficiency and speed of the water digestion treatment is more effective.

Colloids, classified as hydrated silicone solvents or colloids, or lyophilic colloids, are produced when the unmixed liquid is cooled together in the course of condensing vapors during drying and distillation. Proper separation of the liquid from the solvent is affected by the mixing and decomposition of the media and the appropriate separation. The medium chosen serves primarily as the consolidation of very small droplets. The most important factor in shaking the colloid flux is to (1) invert the double layer of electrical charge around the dispersion of the droplets in the lipophilic colloid so that the "zeta potential" disappears, or (2) the droplets in the lyophilic colloid. It destroys the solvated layer or film in the dispersed surroundings. Droplet coagulation and systems lose their stability only when the double layer of charge is stabilized and the solvated surroundings of the drop are removed.

“Permeable structure” mediators can cause coalescence by removing ions from the bilayer or removing the solvated film. Various surface mediators (described but not limited to), which are described later, may attract important valences or other materials, a phenomenon called adsorption, which has different attractive forces left on the distal surface. Adsorption of surface active agents and ions due to “permeable structure” mediators is a reasonable method because the mediators can function and cause coalescence. Therefore, the choice of a "permeable structure" to be used as a coalescing or decomposition medium is eventually based on the ability to separate the siloxane solvent from water.

The present invention includes a method and system for separating water from a silicon based solvent in dry cleaning. According to the invention the inlet can receive a mixture of water and silicon based dry cleaning fluid from the dry cleaning condenser. The chamber is coupled to the inlet to receive the mixture from the inlet. The permeable structure is located in the chamber to separate the dry cleaning fluid and the water. The dry cleaning fluid passes through the pores of the permeable structure. The outlet is coupled to the chamber to remove dry cleaning fluid from the chamber when there is no water.

In one aspect of the invention the cell size of the permeable structure is less than 10 microns. The permeable structure can be an urea-formaldehyde bubble structure. Ideally, the cell size of the urea-formaldehyde bubble is 5 microns or less. Optionally, the permeable structure may consist of polyurethane bubbles, ideally a cell size of less than 5 microns but greater than 10 microns. In another aspect of the invention the permeable structure is hydrophilic.

Optionally, the permeable structure may consist of phenyl group formaldehyde polymer bubbles having an ideal cell size of 10 microns or less.

In one aspect of the present invention the use of fractionation allows for the display of water from solvents based on density and recycle. Low cost boilers such as water can be distilled before the silicon solvent is distilled off.

The ideal distillation of the silicone solvent takes place at temperatures between 235F and 250F with a vacuum of 27inch to 29inch. By providing a temperature above the boiling point of water of 212F and creating a slight vacuum of less than 20, the process can remove steam from low cost boilers and condense the steam in a separate vessel. When boiling together, the water sensor in the vessel will allow the remaining water to exit the system. Residual hydration solvent will return to the distiller to be redistilled.

After the low cost boiler is distilled (based on time or temperature increase), a full vacuum (27 to 29 inches) is produced with the temperature (235F to 250F) generated by distilling the dehydrated silicon solvent. The condensed vapor is sent to a separation vessel with a water sensor that, if present, exits the system for safety. The solvent is returned to the tank of the dry cleaning machine for reuse. The second source of hydration solvent originates from the dry recovery head, which is normally collected in a separation vessel with a water sensor that is very hydrated and allows the removal of remaining water. After the dry recovery cycle, the controlled hydration solvent enters the distillation for distillation so that only the recycled solvent is passed through the low cost boiler vessel of the fractionation scheme.

The use of silicon-based solvents enables temperature ranges that did not exist conventionally in the field of dry cleaning. The importance of controlling the temperature of the liquid solvent used in the dry cleaning field is of great importance.

Most of the widely used solvents described above are PERCs whose temperature is ideally maintained in the 78F to 82F range. This is a common range for all other solvents used in the dry cleaning field. If the temperature must be raised, the solvent will cause more damage to the fibers to be treated. Increasing the kari butyl (KB) value causes most dyes to dissolve in the item to be cleaned and transfer to another item. Interest in temperature control has led dry cleaning manufacturers to install cooling coils in base tanks and inline cooling jackets in piping for heat transfer.

The temperature range of the silicone-based solvents of the present invention is increased from 90F to 130F to allow for the erosion of cleaning without degradation of the pigment. This is accomplished by circulating the water in a closed loop way between the hot water tanks, through the circulation pump and back to the hot water tanks. The circulation pump is controlled by a temperature probe that is placed in the solvent. The result is precise control of the temperature of the solvent which affects the erosion of the solvent without damaging the item to be cleaned. This is optional and not required for good cleaning results.

Various embodiments have been described above, which have been described for purposes of illustration only and not limitation. Therefore, the scope of the preferred embodiment is not limited to any of the above-described exemplary embodiments, but should be formed in accordance with the appended claims.

The above-mentioned advantages and further objects of the present invention should be fully understood by describing preferred embodiments in detail with the accompanying drawings.

The present invention includes methods and apparatus for dry cleaning such as fibers, cloth, leather and the like.

In order to perform the cleaning steps associated with the present invention, a dry cleaning apparatus is shown schematically in FIG. 1 although it is recognized that an optional cleaning structure can be used. It should be noted that the cleaning structure of FIG. 1 is used to handle solvents of class 3-A format (solvents with flash points between 140F and 200F).

Dry cleaning of the items begins with placing them in the horizontal rotating cleaning bin 10. The wash cycle is started with a dry cleaning fluid containing an organosilicon based siloxane solvent using a pump 12. The solvent is pumped from the working tank 14 or fresh solvent tank 12 and moves with the item to the cleaning bin 10. The path of the pumped solvent is directly through the filter 18 or to the cleaning bin 10. Can be

Solvent from cleaning bin 10 circulates through pump trap 20 to pump 12. After exercising for a predetermined time, the solvent is pumped and drained into one of the three tanks 14, 16, 22 shown in FIG. The cleaning pail 10 is then centrifuged to withdraw any residual solution remaining in the tank or still.

Filtration systems of a type compatible with the particular solvents of the present invention can: use diatomaceous soil, which can optionally use larger rotating discs in the form of a rotating disk of 20,60 microns; Pipe filtration (bendable, hard or colliding) devices that can use diatomaceous earth; Cartridges (carbon cores, all carbon in standard sizes or incredibly large or small sizes); Includes Kleen Rite cartridges, which may not be needed in a distiller. Filters can be used in sizes between 10 and 100 microns to filter the condensation vapor before separation.

The solvent can be filtered to remove particulate soil that decomposes from the item to be cleaned. Filtration of the silicon-based solvent also eliminates the polymerization of the solvent even in the presence of a catalyst.

If the Kleen Rite cartridge system described above is not used, the solvent used for cleaning is distilled at a rate of 10 to 20 gallons per 100 pounds. To accomplish this, the distiller 24 may be used to receive solvent from the filter 18 or from the contaminated tank 22 or the wheel 10. The solvent in the contaminated tank 22 can enter the distiller through absorption, since the distiller is under vacuum which can be controlled with a float ball valve (not shown).

Vapor recovered or condensed from the distiller may be condensed into the water cooling coil of the distiller vapor condenser 26. Gravity condensed solvent then enters the first separator 28 or storage vessel. Depending on the still, the flow rate ranges from 0.75 to 2.5 GPM and the separator is designed accordingly. The vacuum is created by the liquid-head pump 30 or by an exhaust treatment process generated by the venturi.

During the drying process, which is sent to the same machine part or dryer, the items are cleaned together with the air generated by the blower 32 against the heating coil 34 which generates an inlet air flow having a temperature between 120-180F. Rolls in). As the water and solvent remaining in the items are heated to become steam, an air flow is passed through the cooling coils of the dry steam condenser 36 where the steam flows into the cleaning bin 10 and the steam is returned to the liquid. Gravity causes this liquid to enter the first separator 28 or through the conduit 37 into the reservoir.

The steam containing air exiting cleaning bin 10 is in a temperature range of 120-160F. The temperature is important and can have the advantage of controlling the temperature to 140F or less, such as 30F which is below the flash point of the solvent described above. In one embodiment, the flow rate of the condensed liquid can be limited to 0.75 GPM, and therefore the separator can be designed for the combined flow rate of the condensed liquid from the distiller and dry steam condensers 26, 36.

2, 3 and 4 illustrate the order in which the various elements of the invention are used for the purpose of classification. Following the dry cleaning process described above, there is no more than one and there is a source of solvent for at least two clothes separate crabs. The ability to return the recondensed solvent back to the dry cleaning system depends on the separator and its efficiency.

To accommodate this efficiency, a method of separating water and solvent is provided, as shown in FIGS. 4, 5, 6. The mixture of silicon-based dry cleaning fluid and water from the item is received from one or two sources of condensation solvent which is distilled and / or dried in the dry cleaning process. For receiving, the mixture enters the storage vessel or directly through a permeable structure that separates the dry cleaning fluid and water. The dry cleaning fluid is then removed in the absence of water and regenerated into the dry cleaning system.

6 is a schematic diagram of a separator for one embodiment of the present invention that may perform the method of FIGS. 4 and 5. In approaching the main chamber 48 of the separator in FIGS. 4, 5 and 6 according to the flow of the hydrating solvent or the mixture of water and dry cleaning fluid, the mixture is a combination filter in which lint or particulate soil flows downward. Filtration 54 may be prevented from entering the separator of FIG. 6, which in turn may be restricted. In order to achieve this filtration the associated medium 54 can span the initial end of the input tube 52. Various mediators of the invention may include nylon or other associated mediators. Pipe connections from the steam condensers 26 and 36 of the dry cleaning of FIGS. 1 and 8 may be piped to terminate at the inlet 52.

The hydration solvent enters the separator of FIGS. 4, 5, 6, where gravity feeds down the input tube 52, which terminates several inches above the interface height between water and dry cleaning. Silicone-based solvents are insoluble in water and are suspended in hydrating solvents until they form droplets of small cell size. Due to the associated weight, water defenses remain below the main chamber 48.

As the entire liquid in the main chamber 48 rises, the float level switch 58 is in turn installed to operate the pump 60. The liquid is then pumped by the pump 60 through a 1 or 2 filter 62 having a filtration ratio of 20 to 50 microns at high and 5 microns at low as shown in FIGS. 4, 5 and 6.

The hydration solvent is then pushed through the permeable structure 64, which can be located in the filter housing 62 or placed in the inline post filter 62 and serves as a "association medium". Preferably, this structure has a cross section between 1/4 and 4 inches and a length between 1/2 and 15 inches and has a cell size of 20 microns. It should be noted that one to three or more separation structures 64 may be located in the line of filter housing 62. Some water droplets are generated as the hydrating solvent passes through the permeable structure 64 and appears on the release side of the permeable structure 64.

The pump 60 may be electric or pneumatic. The use of a pump 60 or optionally a flow method such as a vacuum makes the separation sufficient. The flow method chosen affects 0.5 to 3.5 GPM flow. If the inflow of the hydrating solvent is larger than the permeable structure 64, the relocation of the float level switch 58 to operate the flow controller is set low to allow a large amount of the hydrating solvent. Flow rates can be modified by increasing or decreasing the air pressure or by using a throttle valve.

The hydration solvent passes through the filter or filter 62 from the first vessel 48 through the suction line 59. The hydration solvent is exposed to the decomposition medium 64 and then into the final vessel 68 through the diffuser 65 and into the dry cleaning machine clean tank 16 shown in FIG.

Three outlets are located in the final vessel. At the top is the safety drainage 70 which sends solvent back to the first vessel 48. The medium height line 66 transfers the solvent to the clean tank 16, transfers the bottom line 67 hydration solvent to the first vessel 48, and closes the loop to protect the clean tank 16 from the hydration solvent. Proceed with the process.

If the process is applied to an original equipment manufacture (OEM) system, the main points are the same but the containers can be changed. As shown in FIG. 6, the source of condensed liquid 26, 36 is the same as that of the hydrating solvent entering the first vessel 48, if the first vessel 48 is installed the water sensor 71 is water. Will drain out and activate the valve to close again once the water is removed. The hydration solvent will be circulated due to the added pump 48 or exiting dousing pump 60, which will dissolve the hydration solvent from the container 48 through a filter 62 (10 microns or less). Circulating through the medium 64, the decomposition medium 64 causes the water molecules to form a droplet structure that is detected by the water sensor 71, and then exits from the container 48. This leaves the dehydrating solvent in the clean tank 16 of FIG. 1 so that it can be safely recycled.

Water collected at the bottom of the main chambers 48 and 68 is either manually discharged or discharged by a water float switch that mechanically opens the hinged valve. Also, the probe (not shown), or two conductive contact points, as the water rises to complete a circuit that signals the air or solenoid valve capable of releasing water in the main chambers (48, 68). There is an option. It may be manually discharged to the bottom of the main chambers 48 and 68 to maintain it manually periodically.

The configuration of the main chambers 48 and 68 may be stainless or polyethylene. The structure using carbon steel is not preferable because oxidation and rust can easily occur.
