Abstract

Usage: sawmill and woodworking industry, for chamber drying of moisture-containing materials. The essence of the solution: the device contains a water condenser 3 installed in parallel with the heater 4 and connected to the heater 4, compressor 2 and separator 5. The water condenser 3 prevents air from entering the heater 4, providing stable heat transfer. 1 ill.

Description

The proposed solution relates to the field of chamber drying of moisture-containing materials and can be used in sawmill, woodworking industry or other areas where chamber drying of materials is carried out.
Chamber drying of lumber is carried out mainly with the help of steam-air drying chambers [P.S. Sergovsky, A.I. Sowing. Hydrothermal processing and conservation of wood: Textbook for high schools. 5th ed. - M .: MGUL, 2003. - S. 132-158]. The drying technology provides for toughening of the drying agent (increase in temperature and decrease in humidity of the air washing the pile of lumber) while reducing the humidity of the wood. In this case, it is necessary to stabilize the parameters of the drying agent (moist air) - temperature and humidity. To heat the drying agent in the chamber, a calorifer equipment is installed that changes the thermal power, depending on the required and actual temperature of the drying agent. The humidity of the drying agent is regulated by replacing the moist air in the chamber with drier air coming from the street or utility room (workshop). Exhausted moist air is discharged into the street. As you know, about 2500 kJ / kg (latent heat of vaporization) of energy is spent on moisture evaporation. This energy is lost with the release of air into the atmosphere. To reduce energy loss, on chambers of large volume, recuperators are installed in which the air discharged from the chamber is cooled and the incoming air is heated. However, the efficiency of such systems cannot be high. In winter, almost dry street air, having a low heat capacity, cannot utilize the completely "waste energy" of moist air. In the summer, the recuperator becomes almost useless, because it does not condense moisture from the exhaust air.
A device for chamber drying of moisture-containing materials is known, based on the fact that moist air is not emitted into the atmosphere, but is absorbed by the compressor, compressed, heated, and enters the air heater installed in the drying chamber space [Utility Model Patent No. 83600. A device for chamber drying of moisture-containing materials, 2009]. Moisture condensation occurs in the heater blown by the drying agent, and the thermal energy released in this case is transferred to the drying agent, increasing its temperature. The dried air expands in the heat exchanger to atmospheric pressure, exchanging thermal energy with the air entering the compressor. The disadvantage of this solution is that air enters the air heater together with water vapor, which reduces the heat exchange coefficient of the drying agent with the surface of the air heater.
The purpose of the utility model is to prevent air from entering the air heater, which will increase the heat transfer coefficient.
The solution to this problem is ensured by the fact that a condenser is additionally installed parallel to the heater, into which moist air enters from the compressor. Steam condenses, water enters the air heater, and air is vented to the separator.
The claimed utility model can be implemented as follows. As mentioned above, the drying of lumber is carried out in a vapor-air environment. A device for chamber drying of moisture-containing materials is shown schematically in FIG. 1. The device contains a series-connected heat exchanger 1, compressor 2, water condenser 3, air heater 4, separator 5 and control valve 6. Water condenser 3 is installed in parallel with air heater 4 and connected to air heater 4, compressor 2 and separator 5.
A device for chamber drying of moisture-containing materials works as follows. Wet air (drying agent) from the drying space of the chamber, passing through the heat exchanger 1, enters the compressor 2. Compressed air is sent to the condenser 3, where it is separated into water and air. Water is cooled in the heater 4, transferring energy to the drying agent, and air is sent to the separator 5, where it is freed from water spray. The dried air is returned to the heat exchanger 1. The pressure generated by the compressor 2 is maintained at the required level by means of a control valve 6 installed at the inlet of the heat exchanger 1. Expanding, in the heat exchanger 1, the dried air is cooled and cools the moist air entering the compressor 2. When cooled, the saturation of moist air increases, which further increases the amount of water condensed from the drying agent.
A water condenser prevents air from entering the air heater, providing stable heat transfer.
