Description

one

The invention relates to dry wood materials, mainly veneer.

Gas dryers are known, operating from individual external fireboxes operating under vacuum created by a fan located between the furnace and the drying chamber l.

The disadvantage of these dryers is the impossibility of the flue gases fan in them with a temperature higher than the EZGS. The presence of the longitudinal circulation of the drying agent limits the intensification of the drying process and impairs the quality of the material being dried (hemming, changing the color of the material).

The closest to the proposed one is the dryer, which contains a sectional junction chamber with a compartment separated from the working space (in which the transport device for materials is placed), horizontally, with a partition with windows, and a compartment with side discharge and suction, 1 in each section of the chamber. In the sections B8HT alternate (1 tori and thin. To provide the Dryer with a high-temperature drying agent, the furnaces in the dryer are under a vacuum 2.

However, several dryers are necessary for these dryers, which leads to a loss of up to 4O% of the total length of the dryer due to its absence of intensive circulation of the gas-air mixture. This reduces the productivity of the dryer and increases the cost of operating a significant number of furnace devices.

The aim of the invention is to increase the productivity of the dryer.

This is achieved by the fact that a horizontal distribution manifold with openings is placed along the entire length of the preheater in the compartment along its entire length

help the flue duct to the firebox, made of cyclone type and working under iadduvom.

FIG. 1 schematically depicts the proposed dryer, plan; in fig. 2 is a section along A-L of FIG. one.

The dryer contains a partitioned chamber 1 with a compartment 2, separated from the working space of the chamber by horizontal rehoO) One horizontal section of the wall from the working space of the chamber 3 s; Windows 4 and 5, connecting two compartments with lateral discharge 6 and suctioned 7 kaps in sections 8 of chamber 1, each. In each section of the chamber- 1, fans 9 are installed, which are powered by Wiigatepey 10. In the working space of chamber 1 transporting device 11 is placed. In the compartment 2, a horizontal gas distribution manifold 12 with openings Ii3, connected, is placed along its entire length. | By means of a remote flue 14 to a furnace 15 made of a cyclone type and I work with a supercharger 16, working 16 melting from the ectrodpatel 171 The spent heat carrier is removed through burs 18. The dryer works as follows. The dried material is transported along transporting device 11 along: chamber 1. Fan 16 blows fresh air into the cyclone furnace 15 to burn fuel. The pressure in the furnace 15 (above atmospheric) provides high temperatures of EOi gas-air mixture 000-100c. through the gas duct 14 into the distribution manifold 12, from the "third hole 13, the gas-air mixture enters compartment 2. Here it is mixed with the exhaust gas-air mixture coming from the working space of chamber 1 through OKtie 5. The fans 9 heat the gas-air mixture from the working space camera 1 through the window 4 in the partition 3 to the material to be dried. Part of the exhaust gas-air mixture into the channel 7 of the corridor through the burs 18 is removed by a fan (not shown) to the atmosphere. The main mass of the fan 9 is recycled.
