Device for cleaning the exhaust gases of texturing machines

This invention relates to improvements in apparatus for cleaning the exhaust gases of texturing machines.

When texturing, the yarn runs through heaters and oil and vapors are passed from the heaters to a centrifugal separator / to extract all oil particles from it. «-"

According to the invention, oil vapors are extracted from the heaters of a texturing machine to an electro-optical or other oil cleaner , the purified air being expelled to the atmosphere or returned through a Z always air conditioning system or recirculated through a humidifier.

The invention is made with reference to the sanctifying drawings described.

It shows:

Fig. 1 is a schematic elevation of the device;

Fig. 2 is a perspective view of an oil and steam extractor for the exhaust gases;

Fig. 3 is a perspective view of an alternative extractor for exhaust gases from the heater 1 of a texturing machine.

In carrying out the invention, exhaust gases from the heaters 1 are sucked in by a fan 2 and flow along a line 3 into a puller 4 to remove the oil and fumes from the exhaust.

The oil and steam extractor 4 is preferably an electrostatic one Ventilation filter in which all particles in the air are included that microscopic y-size is electrostatically (positively) charged when they flow through a high voltage ionization grid. The particles are then attracted to collecting plates and adhere consider which the negative elements form an electrostatic field that is built up between a series of parallel plates which are periodically alternately positively and negatively charged, depending on the dirt content of the air ^ & Le

Accumulation of dirt must be removed from the collection cell.

An electrostatic air filter for extracting oil and vapors from the exhaust gases is illustrated in Fig. 2, in which oil mist 5 from the line 3 first through a mechanical pre-filter 5a which removes any large particles. The cleaned air then flows through an ionization section 6, in which the particles receive a positive charge which is produced by a power supply unit 7 at high voltage.

The ionized or positively charged particles are then sucked in or through negatively charged collecting plates 8 made of aluminum collected. This gathering is carried out under the magnetic law that like poles repel and unlike poles attract. The collecting plates 8 are alternately charged positively and negatively, so that the negative plate 8 attracts the positively charged particle, while the positive plate 9 at the same time a repulsive one Has an effect on the positive particles because of their positive polarity.

The collected oil particles then run down the collecting plates 8 and are collected in a bowl Io and returned to a storage container 11a for reuse via a small pipe 11 , this drainage process also cleaning the plates 8.

The purified air 12 is blown by a blower 13 from the filter

sucked off and circulated again through a line 14 or expelled to the atmosphere when necessary. Two-way damper 15f 16 are provided in the line 14.

The exhaust gases can also be sucked in by the fan 13 through an air cooler 17 (FIG. 3), which has a cooling medium circulated by pipes 19, and the oil condensed from the gases is filtered through a filter medium 18 and collected in the bowl Io, as above described.

The clean air 12 flows through the line for recirculation and becomes the room air through a conditioning cylinder 21 sucked by a fan 22 d and expelled from the lines 23 into the room.

As described, air flows from the extractor 4 to an outlet line 24 for expulsion to the atmosphere through the two-way damper 15. or a valve for transmission through line 14 to the conditioning system for the room air or a humidifier through a pipe to the recirculation.
