Abstract

The invention relates to devices for steam processing of textile materials and makes it possible to expand technological capabilities in steaming textile materials dyed with dyes that are particularly sensitive to moisture and chemical composition of steam. The device comprises means for transporting the material to be processed, a skeleton with a ceiling and a bottom heated by a hollow steam, and means for introducing into the chamber the direct steam and water in the form of condensate. In this case, the steam is produced in the generator by boiling up the condensate fed into it while simultaneously injecting steam from the heat point. At the same time, a vertical pipe is installed in the generator, forming a hydraulic lock with respect to the drain fitting for locking the steam. The device can operate in three modes: wet saturated steam in the chamber, dry saturated steam in the chamber, superheated steam in the chamber. 1 hp ff, 1 ill.

Description

The invention relates to devices used in the textile industry and can be used in steaming textile materials dyed with dyes that are particularly sensitive to moisture and chemical composition of steam during the steaming process.

The purpose of the invention is to expand the technological capabilities of the device by creating an atmosphere of high-purity, moist steam.

The drawing shows a device for steam processing of textile materials.

The device comprises means 1 for transferring the material to be processed 2, a skeleton 3 with ceiling debris heated 4 and a bottom 5 and means 6 for introducing live steam into the chamber and means 7 for introducing water.

The means 7 for introducing water is connected but with a pipeline 8 for draining condensate from the internal cavities of the ceiling 4 and the bottom 5.

The means for introducing live steam is provided with a generator 9 of wet saturated steam, made in the form of a hermetic vessel 10, separated by

the horizontal partition 11, through which the pipe 12 passes vertically open at both ends, is placed in two parts. In the upper part of the vessel there are nozzles 13 for supplying steam from the heat point and a pipe 14 for supplying condensate. In the lower part of the vessel 10 is mounted a pipe 15 for draining excess condensate

In generator 9 of saturated saturated steam, pipe 15 for draining excess condensate above the lower cut of the vertical pipe 12.

The steam from the heat point is supplied through the valve 16. From the internal cavities of the ceiling 4 and the bottom 5, the condensate is removed through the steam traps 17 and 18. The pipe 8 for the condensate drain is connected to the means 7 for introducing the condensate to the bottom 5 through the valve 19. The valve 20 is connected by a condensate heat line and the valve 21 connects the pipeline 8 through the pipe 22 with the upper cavity of the vessel 10 of the wet steam generator. The bottom 5 above the liquid level is covered with a perforated sheet 23 to protect the material 2 to be treated from splashing from the bottom when the liquid boils.

The device works as follows.

Condensed deaf steam when heating internal cavities of 4 and bottom 5 through condensate traps 17 and 18 is supplied through pipeline 8 through valve 19 by means of means 7 to bottom 5, Condensate It is a superheated water that does not contain volatile substances. Hitting the bottom 5, the condensate boils up due to its excess heat and releases saturated steam into the chamber.

Through valve 16, steam is supplied to the nozzle 13 from the heat point, having a temperature much higher than 10 ° С, i.e. overheated with respect to the atmosphere. From nozzle 13 it goes into boiling condensate, gives it its excessive heat and passes through means 6 into the chamber already in the form of a saturated vapor, which additionally removes the overheating created in the chamber by the ceiling 4. As a result, a saturated maximum vapor atmosphere is maintained in the chamber. high humidity

 what is required by technology.

In the lower part of the vessel 10 there is a hydraulic interception preventing the passage of steam into the pipe 15.

This device provides

Q two more modes of operation on superheated steam and on dry saturated steam. They lead to marriage when dyeing with active dyes on natural silk, but can be useful when dyeing disperse dyes on synthetic fabric.

To obtain the mode In the chamber, overheated steam closes valve 19 and opens valve 20. Valve

Q 21 remains closed. Then from the heat point through the valve 16 freely passes into the chamber. In this case, there is no liquid either in the chamber or in the generator 9, as well as steam overheating is increased by the hot ceiling 4 and the bottom 5.

Mode In the chamber, dry saturated steam is obtained with the valve closed.

19 and open valve 21. Valve

20 closed and running

Q is only a generator 9, the bottom 5 is dry and additional steam is not moistened.

This device allows the processing of yarn and fabrics in a wide range.

Excess condensate, through pipe 14, drainage, for their range depending on

At the same time, the valves 20 and 21 are closed.

The condensate fills the vessel 10 in its upper part along the upper cut of the coarse 12. Above it cannot rise, since the excess through the pipe 12 flows into the lower part of the vessel 10 under the partition 11. But there the condensate also cannot rise without limit, up to the partition 1 1 ,, It can only rise as far as pipe 5 and flow through it into the vessel for 7-liva.
