いる。 A spray head with a nozzle opening, a ram arranged inside the spray head and movable through the nozzle opening, and optionally a filter set with a scraping device arranged between the inlet of the dispersion system and the nozzle opening. A device for spraying dispersions, in particular suspensions, is known from DE 27 24 931 A1. In order to work satisfactorily with this device and to obtain a homogeneous spray layer, the nozzle opening must be kept to a minimum.
It must have a diameter of 0.3 mm and must maintain a minimum operating pressure of 20 bar. This means that the flow rate cannot go below a certain level.
That is, during spraying, the dispersion is applied as a very thick film. It is therefore proposed in European patent application no.
It is proposed in specification No. 39839. The air-sparging nozzle allows for very good control of the spray volume;
It is particularly suitable for uniformly scattering small amounts of material.

的に遮断してしまう。 It has become clear in actual use that due to the film-forming nature of the polymer, deposits formed during continuous operation impede the operation of the air-sparging nozzle. During needle penetration and cleaning when a liquid nozzle is blocked, the film-forming polymer gradually forms a deposit that prevents and eventually blocks air flow.

る。 This purpose is achieved in claim 1 according to the invention.
This is achieved by the method described in Section 6 and the apparatus described in Section 6. According to the method of the invention, air is advantageously used as the blown gas and water is advantageously used as the liquid. Air is generally used especially for economic reasons, but nitrogen,
It is also possible to use other gases or mixtures thereof, such as CO 2 , halogenated hydrocarbons or inert gases, or mixtures thereof with air.

ともできる。 Similarly, water is used as the liquid for economic reasons. However, as a liquid, the number of carbon atoms is 1 to 8.
It is also possible to use alcohols, glycols, glycol ethers or glycol ether esters, or mixtures thereof or mixtures with water. In some cases, the liquid may also include an organic water-soluble oil component or an oil-in-water type emulsion.

利用する。 Liquids can be mixed with gases in a variety of ways. For example, a liquid can be vaporized and added to a gas stream.
Alternatively, the liquid can be sprayed into the gas stream. For this purpose, devices such as dosing pumps, pressure vessels with dosing devices, negative pressure dosing devices, etc. are used, for example.

る。 According to the method of the invention, the pressure gas must be saturated or supersaturated with liquid. Thereby, the degree of saturation must be maintained in accordance with the approximate degree of saturation, as brought about, for example, by changes in the volume of the pressurized gas and by changes in temperature. In this case, supersaturation does not only mean a state of supersaturation, but also in a broad sense, especially the presence of liquid in the form of fine particles in a fog, that is, in a pressurized gas.

結果、分散質が懸濁液から遊離してスプレー装置
に付着する。 Keeping the pressure gas saturated or supersaturated with liquid has the effect of preventing the formation of a crust (shell of solid matter) inside and outside the nozzle. If the pressure gas is not saturated with liquid, the dispersion medium of the suspension to be sprayed will evaporate and be extracted into the pressure gas, with the result that dispersoids will be liberated from the suspension and deposited on the spray equipment. .

と混合し、懸濁液が霧になつて吹き出される。 When spraying a suspension with the device according to the invention, if there are any unwanted large particles entrained, they are captured by the filter set 6. A pressure gas saturated or supersaturated with liquid is forced out through a pressure gas supply channel 8 opening into the spray nozzle. Before the nozzle opening 3, the saturated or supersaturated pressure gas mixes with the suspension and the suspension is blown out as a mist.

それらが捕そくされる。 The piston 5 moves the ram 4 fixed to it in the opening direction, ie the ram tip is pulled back from the nozzle opening 3, opening the flow path for the suspension. When the piston 5 is driven in the opposite direction, the ram tip penetrates into the nozzle opening 3, pushes out any dirt and closes the nozzle opening 3. piston 5
The surface of the filter set 6 connected to the filter set 6 is rubbed during the closing process, so that the surface of the filter set 6 is cleaned. In the final position, the entire surface of the filter set 6 is covered with a bush 7 or scraping device, closing the flow path for the suspension. piston 5
When returned, the suspension passes through filter set 6 and if there are excessively large particles or dirt,
They will be captured.

た圧力ガスがノズル開口３に流れる。 In the apparatus shown in FIG. 2, a capillary tube with a diameter of 0.4 to 0.6 mm, preferably 0.5 mm is disposed in the piston 5, and when the spray is stopped, the moist water is passed from the pressure gas connection port 12 through the capillary tube 14 and the pressure gas supply path 8. Pressure gas flows into the nozzle opening 3.
それによつて圧力ガス供給路８が懸濁液の逆流
