The method for safety control of the drying cycle in hydrocarbon-solvent dry-cleaning machines, comprising, in the first step of the drying cycle, when the temperature of the mixture of hot air and solvent at the outlet of the drying drum reaches values which are higher than a preset safety value passing, the drying air, before being returned to the drum, through an additional separator-heat exchanger having a high thermal capacity. The apparatus is constituted in particular by the additional separator-heat exchanger connected through at least one valve driven by a detection to the drying circuit of the machine.

A method and apparatus are described for cleaning fabrics and clothes in a liquid medium wherein a vacuum drying step is effected at a pressure ranging from 1.5.times.10.sup.3 Pa to 15.times.10.sup.3 Pa in the presence of steam which is injected into the drying process at a pressure between 0.8.times.10.sup.4 to 8.times.10.sup.4 Pa and which is used as a carrier for removing the cleaning liquid.
摘要:
The present invention is directed to a technique which comprises the steps of stopping the rotation of a treating drum in a deodorizing step, introducing the outside air into a treating tank through an upper opening provided in the upper portion of the treating tank or the upper portion of a recovery air duct, simultaneously exhausting a solvent gas from the treating tank through a lower opening provided in the lower portion of the treating tank or a button trap portion so slowly as not to agitate the solvent gas in the treating tank by an exhaust means connected to a solvent recovery device in the condition that the treating drum is stopped, in order to replace the solvent gas in the treating tank with the outside air, and reusing the solvent gas through the solvent recovery device once or several times. In addition, the present invention is further directed to an improvement of the above-mentioned technique. According to the above-mentioned technique of the present invention, a gas throughput which is required to recover a certain amount of the solvent in the treating tank can be noticeably miniaturized and hence it can be manufactured at a lower cost, as compared with conventional ones, and air pollution and the breakage of ozone layer can be prevented. Moreover, the solvent can be saved owing to its recovery and reuse, and occupation space for the solvent recovery device can be also saved.
摘要:
A dry cleaning liquid recovery unit which can be used integrally with a dry cleaning system, or as a separate stripping, drying and recovery unit to effectuate liquid recovery and rapid drying of fabrics and clothes placed therein without creasing. The recovery unit has an improved thermal heating unit which can be converted to a cooling unit for cooling the circulating air which allows the garments or fabrics in the recovery unit to be cooled down prior to removal and extended piling thereof.

Controls for a solvent recovery apparatus regulate the flow of coolant in a condenser coil responsive to the temperature of air circulating in a closed pathway through a tumbler.
摘要:
A cleaning apparatus particularly for textile articles, the operation of which comprises the steps of subjecting the mechanically agitated articles in an initial phase to the action of a solvent in conjunction with mechanical action in an enclosed cleaning space, following in a second phase to the action of a pulverized aqueous solution prepared beforehand in a vessel external to said enclosed cleaning space and in which said solution has its water content proportioned and its temperature governed, said second phase being effected in conjunction with preferably reduced mechanical action.
