Description

The invention relates to the technique of ventilation and air conditioning and is an improvement of the device according to aut. No. 1353992.

The aim of the invention is to improve the parameters of the supply air.

FIG. 1 is a schematic diagram of a ventilation device for creating a clean zone, side view; in fig. 2 - the same, top view) in FIG. 3 is a plate with an electrically conducting tape and a series of needle-shaped electrodes and a protective grounding screen.

The ventilation device for creating a clean zone contains a pressure chamber 1, a baffle 2, an upper perforated grid 3 with a coefficient

forged strips 3 with a living section coefficient of 0.2-0.3 and a lower perforated grid 6 with a living section coefficient of 0.4-0.5.

At least two plates 7 made of dielectric material 25 are located along and perpendicular to the ultimately perforated strips 5 and are rigidly connected to the latter.

Plates 7 have corresponding electrically conductive tapes 8 and are connected to the HWM sets of needle-shaped electrodes 9, which are mounted on the respective plates 7 opposite to each other.

Electrical conductor pshe tape 8 is connected to the opposite poles of the DC source (not shown).

Plates 7 can have protective grounded screens, made in the form of a metal grid 10, covering the corresponding rows of needle-shaped electrodes 9 outside.

The casing 4 is communicated by the input 11 and the output 12, respectively, with the atmosphere and the consumer (not shown).

Making the plate 7 with grounded screens, made in the form of a metal grid 10, externally corresponding to the needle-shaped electrodes 9, makes it possible to regulate the saturation of the treated with azroions, and also serves as a remedy for sonal electrical shock.

Claims (1)

Invention Formula The ventilation device of the tribute to the clean zone according to the author. In order to improve the microclimate of the zone, the device additionally has plates with electrical conductors and needle-shaped electrically mounted on the extreme perforations, while the plates with protective grounded shields are filled with metal and covered with a row of electrodes outside. The ventilation device,; jiH creating a clean zone operates as follows. The treated air through the inlet 11 enters the inside of the casing 4 and successively passes the baffle 2, the perforated grill 3 and the perforated strips 5, while the air is evenly distributed over the entire cross section of the casing 4. With the passage of air between the rows of electrodes 9, the air is ionized and filled with aero ions. The formation of air ions occurs near the needle-shaped electrodes 9, the electrically conducting tapes 8 of which are connected to opposite poles. direct current source. The implementation of the plate 7 with protective grounded screens, made in the form of a metal grid 10, covering outside the corresponding rows of needle-shaped electrodes 9, makes it possible to control the degree of saturation of the treated air with azroions, and also serves as a means of protection from electric shock to personnel. Invention Formula Ventilation device for creating a clean zone by author. St. 1353992, characterized in that, in order to improve the microclimate of the clean zone, the device further comprises plates with electrically conductive tapes and needle-shaped electrodes mounted on the extreme perforated strips, while the plates are provided with protective grounded screens, made in the form of a metal grid and cover them with the outside corresponding rows of electrodes. 7-5-8 Editor I.
