SU549648A1 - Exhaust air dryer - Google Patents

Description

The invention relates to the ventilation and air conditioning and can be used to dry the air mainly in the regions of the Extreme North and Northeast with an outdoor air temperature of up to 70 ° at any internal air temperature.

A known unit for drying the air, comprising a fan with an electric motor, an air distribution casing, drying elements, a mortar bin 1.

As a result of the operation of the fan, moist air is sucked in through the windows of the solution container and, as it passes through the drying elements, enters the casing. Next, dried air comes out through the hole.

Such an installation does not provide effective drainage of exhaust air.

Another device is known. T. condensation of moisture from the outgoing ventilation air, made in the form of a heat exchanger consisting of a series of channels, the partitions of which are ventilated on one side and external air on the other side 2.

The device is mounted at the mouth of the mine. The ventilation air, rising, washes the heat exchange surfaces. These surfaces are assembled from a series of flat, rectangular ducts and are connected between each other, with each other, so that between them channels are formed

passage of outdoor air. The internal warm air rises through the duct, the external cold over the gaps between the duct, passes in a horizontal direction. The warm exhaust air is cooled by contact with the cold duct surfaces, which on the other side are surrounded by ambient air. Moisture condensation from warm air occurs on these surfaces.

In order to prevent icing from condensation and moisture on the walls of the heat exchanger, its sections are mounted on the B-axis.

This device is the closest to the invention but the technical essence and the achieved result. However, such a device does not desaturate the effective drying of exhaust air.

The aim of the invention is the improvement of drying efficiency.

This is achieved by the fact that the device is made with a two-stage heat transfer and moisture in the form of a naturally ventilated box placed under the ground and contained in it and a condensate collector installed in the form of a truncated cone connected to the BO; IO outlet. Condeisatron is equipped with a reflector and exhaust duct diameter

which is at least twice the diameter of the exhaust duct. The drainage system is placed in an electrically heated housing.

FIG. 1 shows a device, a longitudinal section; in fig. 2 is a cross section of FIG. one.

The device for drying exhaust air contains a fan /, exhaust duct 2, a condensate collector 3 mounted on it, made in the form of a truncated cone. The condensate collector 3, located in the naturally ventilated with the help of the inlet 4 and 5 outlets, under the ground box 6, is provided with a reflector 7 of the exhaust air for moving and directing it around the walls 8 and the exhaust duct 9, the diameter of which is less than twice the diameter of the exhaust duct. The system of organized drainage consists of a drainage chamber detachable chamber 10 located in an electrically heated casing I, including an ice-reel for the period of thawing. Dynods removable camera 10 with a pipeline connection 13.

Exhaust air from the premises of the ventilation unit assistance / enters through the exhaust duct 2 into the condensate collector 3, made in the form of a truncated cone and located in the naturally ventilated box 6, which is located by the ground. At the same time, the speed of movement. The exhaust air decreases dramatically, since the cross section of the exhaust duct 2 is much smaller than the cross section of condensate chamber 3. Since the exhaust air temperature and humidity are significantly lower than the air temperature in the naturally ventilated duct, and the wall temperature of the condensate collector, the exhaust air is gradually cools around walls 8 and reflector 7 and gives off excess moisture. With appropriate combinations of exhaust air temperature and air inside a naturally ventilated heat-insulated box, a dew point is formed in the condensate collector, which results in condensate water. Then

The cold air is exhausted through an exhaust air duct, the diameter of which is at least twice as high as that of the exhaust air duct, is thrown out. In the condensate collection, the moisture enters the collection catchment chamber 10. After the catchment collection chamber is filled with ice, it is turned on for the period of complete defrosting of ice.

the electrically heated housing 11, then, but as far as thawing, the water at the bottom / 2 of the catchment chamber is discharged into the pipeline 13 of the organized drainage system. In the case of carrying abatyvany electric heating, catchment

the camera can be removed and warmed up.

For natural ventilation of the insulated duct-with an MK, placed under the ground, there is a 4-point air outlet and a 5

nozzles.
