Definitions
- the present invention relates to a method and an installation for drying a mass of wet fibrous material, in particular a mass of laundry washed and placed in a washer-dryer machine or a dryer.
- the document WO No. 89/04392 discloses a method and an apparatus for drying, by means of superheated steam, a mass of laundry contained in an enclosure.
- the superheated steam is caused to circulate through the enclosure, in a closed circuit, by means of a fan mounted upstream of the enclosure and downstream of a heat source so as to discharge into the enclosure the steam d water evaporating from the laundry.
- the air contained in the enclosure is discharged through a vent to which is connected a condenser connected in bypass.
- Document EP-A-0 026 707 discloses a drying method and installation in which the drying cycle includes a first spin phase in which we do. ? . circulate through an enclosure, containing the material to be dried, water vapor produced by an independent steam generator and a second phase in which is circulated, by means of a fan plugged upstream of the enclosure, the water vapor evaporated from the wet material, this water vapor passing through a superheater.
- a condenser is connected in bypass at the outlet of the enclosure containing the wet material.
- the present invention relates to improvements in known drying methods and apparatuses which make it possible to significantly reduce the overall duration of drying a mass of fibrous material and to considerably reduce the cost of the drying installation.
- this method of drying a mass of wet fibrous material, in particular a mass of wet linen after washing in which steam of the fibrous material is passed through in a closed circuit water superheated at a temperature between 102 ° and 180 ° C and substantially at atmospheric pressure, characterized in that it comprises, before the drying phase with superheated steam, a prior phase of flushing the air, present in the closed circuit, by means of water vapor.
- the subject of the invention is also an installation for drying a mass of wet fibrous material, in particular a mass of wet linen after washing, comprising an enclosure in which the mass of wet linen is housed, a steam generator, a superheater, a condenser, and a fan for circulating, in a main pipe in a closed circuit, steam, superheated to a temperature ranging from 102 ° to 180 ° C., through the enclosure and the mass of wet fibrous material which it contains, characterized in that the fan intended to ensure the circulation of water vapor is constituted by a fan extractor connected, on the main pipe, downstream of the enclosure outlet, in order to create a slight vacuum in this enclosure, the condenser and the superheater are connected in series upstream of the enclosure, the main pipe is connected, on the discharge side of the fan, on the one hand to a first air solenoid valve, connected in bypass, and on the other hand to a second solenoid valve connected in series and the steam generator is connected to the main pipe
- the drying method and installation according to the present invention offer the advantage of allowing a simplification of the installation. Indeed, the prior rinsing of the closed circuit of its air, by means of water vapor, before the actual drying phase, allows the installation to operate at atmospheric pressure and the temperature of the vapor at the interior of the drying chamber is therefore always greater than 100 ° C. for normal atmospheric pressure. This can significantly reduce the cost of a dryer according to the invention because it is not necessary to use sophisticated sealing devices (gaskets etc ).
- the drying installation comprises an enclosure 1 in which is placed the mass of fibrous material to be dried which will be considered, in the context of the present description, as being damp linen as it appears after washing.
- the enclosure 1 can be constituted by a drum set in rotation by mechanical drive and which can rotate alternately in both directions, so as to stir the laundry.
- the enclosure 1 can also be constituted by a dryer in which the laundry items are stationary by being suspended in an appropriate manner.
- the enclosure 1 can also be of the type with continuous circulation of the pieces of linen, from an inlet to the outlet of the enclosure.
- the enclosure 1 is connected to an outlet duct 2 in which is housed a centrifugal fan 3 creating a vacuum in the enclosure 1 when it is started.
- the outlet conduit 2 is connected to a main pipe 4 connected in a closed circuit with the enclosure 1 and connected for this purpose to an inlet orifice of this enclosure.
- This main pipe 4 is intended for the circulation, in a closed circuit, of superheated water vapor and / or air, as will be explained below.
- a solenoid valve 5 also forming a vent valve, calibrated for example at a pressure of 1.05 bar absolute.
- Downstream of the connection point of the solenoid valve 5 is connected another solenoid valve 6, in series in the pipe 4, and downstream of this solenoid valve 6 is connected in diversion another solenoid valve 7 connected to the upper part of a generator. steam 8.
- a safety valve 9 calibrated at a pressure of 1.2 bar absolute for example.
- the steam generator 8 is connected to a source of water by means of a valve 11 and it includes an electric heating device 12 to cause the vaporization of the water contained in the generator 8.
- a steam condenser 13 On the pipe 4 is connected in series, downstream of the steam generator 8, a steam condenser 13 provided with an air or water cooling circuit 14.
- the condenser 13 is adjusted so that the condensation temperature is always slightly higher than the saturation temperature corresponding to atmospheric pressure, that is to say 100 ° C for normal atmospheric pressure.
- the condenser 13 contains a float 15 connected to a level sensor 16 detecting the water level in a condensate recovery tank 17 located at the bottom of the condenser 13. Below the condensate recovery tank 17 is a condensate tank 18 After the condenser 13, that is to say downstream in the direction of circulation of the vapor, the main pipe in closed circuit 4 comprises a solenoid valve 19 connected in series.
- the pipe 4 is then connected to the inlet of a superheater 21.
- This superheater 21 comprises an electric heating circuit 22 producing superheating of the steam at a temperature ranging from 102 ° C to 180 ° C.
- a solenoid valve 23 is connected to the pipe 4 to allow air to be admitted into the main circuit.
- the steam generator 8 could be associated with the superheater 21, forming a single unit supplying heat. steam superheated from liquid water.
- the installation can also include a dehydrator
- the dehydrator 24 connected in parallel to the solenoid valve 19 and connected to the main pipe 4, on either side of the solenoid valve 19, by two solenoid valves 25 and 26.
- the dehydrator 24 comprises a matrix of a desiccant material capable of absorb or adsorb water vapor and can be regenerated by heating by means of an electric heater 27.
- the temperature of the fluid (water vapor and / or air) flowing in the main circuit 4 is controlled by means of two thermal probes 28, 29 mounted respectively at the inlet and at the outlet of the enclosure 1, so detecting the inlet temperatures T1 and outlet temperatures T2 of the steam passing through the enclosure 1.
- the various solenoid valves 5,6,7,11,19,23,25,26, the heating circuit 12 of the steam generator 8, the heating circuit 22 of the superheater 21 and the heating device 27 of the dehydrator 24 are connected to a general automatic control circuit 31 which regulates the operation of the installation.
- This device 31 is also connected to the centrifugal fan 3 to control the starting and stopping of this fan.
- the device 31 also receives information from * the level sensor 16 of the condenser 13 and the thermal probes 28 and 29.
- the drying process comprises a first phase during which the moist air normally present in the main circuit 4 is replaced by steam, superheated or not, circulating in an open circuit.
- This humid air is in enclosure 1 and 10 the humidity and the temperature of this air are variable.
- the automatic control device 31 causes several simultaneous operations, namely, starting the steam generator 8, so as to produce in this steam generator a temperature of 15 102 ° C, l opening of the solenoid valves 5 and 7, closing of the solenoid valve 6, starting the fan 3 and possibly starting the superheater 21.
- the fan 3 creates a vacuum inside the enclosure 1, if although the steam produced by the steam generator 8 20 flows successively through the solenoid valve 7 open, the main pipe 4, the condenser 13 whose external cooling system is stopped during this phase and the solenoid valve 19 open and it is introduced into the superheater 21 then into the enclosure 1 and this vapor drives out 25.
- This first phase of flushing and replacing the humid air with water vapor, possibly overheated lasts a predetermined time 0 which can be easily calculated from the volume known to the facility.
- the automatic control device 31 causes the solenoid valves 5,7 to close, the steam generator 8 to stop and the solenoid valve 6 to open, which establishes a closed circuit for the subsequent circulation of the steam. .
- the drying process then passes to a second phase or main phase during which the laundry contained in the enclosure 1 is dried by the superheated steam and the water extracted from the laundry is condensed continuously in the condenser 13.
- the automatic control device 31 causes the superheater 21 to be put into service, if it was not already there during the first phase of flushing the air.
- the fan 3 continues to rotate, producing the circulation in a closed circuit of the steam which is superheated in the superheater 21.
- part of the steam condenses and the condenser thus removes a progressively increasing amount of water from the closed circuit, allowing optimal operation of the dryer.
- the power of the condenser 13 is controlled by the temperature T2 at the outlet of the steam from the enclosure 1. In fact, as the drying progresses, the flow of water extracted from the laundry decreases, the temperature T1 increases and the power of the condenser 13 decreases.
- the level of condensate collected in the recuperator 17 is detected by the float
- This sensor 16 makes it possible, together with the temperature probes 28 and 29, to determine the end of drying. In other words, when the level sensor 16 detects that the level of water condensed in the condensate collector, 17 hardly changes any more and the temperature probes 28 and 29 indicate that the inlet temperatures T1 and outlet T2 are practically identical, this means that the laundry has reached its final drying point. At this time, the automatic control device 31 automatically stops the drying cycle.
- the main phase of drying using superheated steam can optionally be followed by a third phase of drying using dry air.
