Description

one

The invention relates to the production of smoked products, in particular to smoke generators.

Smoke generators are known, consisting of a smoke chamber with a grate, mounted above the last hopper for sawdust, placed on the vertical shaft of the agitator to loosen the 66iHiKepe olilok and -stirmi for a time: wedge, and they have a grill, and they are mixed for a time: by filters.

However, the known smoke generators do not provide high-quality smoke and are very labor-intensive.

In order to produce high-quality smoke without carcinogenic substances such as 3,4-benzpyrene in the proposed smoke generator, water sprays connected to a thermostat to control the temperature of the resulting smoke are installed between the filters of the smoke purification chambers in the upper part of the smoke chamber. .

To change the thickness of the sawdust layer on the spiked grid, the shaft of the agitator and the dresser is freely connected to the gearbox on the threaded coupling and has a guide coupling on the lower section of the central shaft.

The grate is made of rotary sections to remove ash and sclac.

FIG. I is shown schematically, the proposed smoke generator in section; in fig. 2 - the same plan view.

The smoke generator consists of a chamber / smoke generation with a grate 2, a hopper 3 with a throat 4 placed on the vertical shaft 5 of the agitator 6 for loosening sawdust in the bunker and a paddle agitator 7 for leveling it on the grate and a water spray gun S connected to a temperature range, connected to a heating grid S connected to the grid, connected to a grid and connected to a heating grid S connected to a grid and connected to a heating grid S connected to a grid and connected to a heating grid S, connected to a grid and connected to a heating grid S, connected to a grid and connected to a heating grid S, connected to a grid and connected to a heating grid S, connected to a grid and connected to a heating grid S, connected to a grid and connected to a heating grid S, connected to a grid and connected to a heating grid S, connected to a grid and connected to a heating grid S, connected to a grid and connected to a heating grid S, connected to a grid and connected to a heating grid S, connected to a grid and connected to a heating grid S, connected to a grid and connected to a heating grid S, connected to a grid and connected to a grid of air drift 9.

A drive 10 is mounted above the bunker. Shaft 5 is led to the drive reducer by means of a threaded coupling //. The lower end of the shaft is located in the guide bush. The threaded sleeve is intended to change the thickness of the layer of sawdust on the collar bar by changing the position of the sleeve with blades 7.

The grate 2 is made of separate rotary sections (" not shown), which rotate around their radial axes.

The smoke generation chamber 1 is connected to the smoke cleaning chamber 12, in which filters 13 and 14 and the water sprayer 15 are located. Filter 13 consists of rings “Raschiga with a layer thickness of about 30-40 cm and is intended for cleaning smoke from fur contaminants and free resins Filter 14 consists of small rings “Raschiga layer about 20 cm thick.

The chamber 12 is provided with a fan 16 for exhausting smoke, a centrifugal non-film scrubber 17 for fine cleaning of smoke, an electrostatic filter 18 and an electric heater 19.

The entire filter system is periodically poured and steamed with live steam through a conduit 20. At the bottom of the chamber 12 there is a constant layer 21 of water for extinguishing sparks.

Smoke generator works as follows. ,

The smoke generator works on sawdust with moisture to smoke, produced by the smoke generator, has high activity and a high content of aromatic and preserving components without hydrocarbon content of type 3,4-: benzene, as the formation of smoke occurs at a temperature in the area of the mountain and within plus 270-300 ° C.

Sawdust flows in a continuous stream through the throat of the hopper 3 into the smoke generation chamber 1 to the grate 2 with a layer of thickness, another 4-7 cm, depending on the set mode. In this layer of sawdust, their smoldering occurs and H1NteisN | VNoe the formation of smoke.

The stability of the sawdust layer is maintained continuously, vrash, ayush, with a stirrer 7. The coarse adjustment of the flow of sawdust to the grate is dried, leveled by means of a movable coupling 22 and a system of levers.

The bulk of the air (about 90%) is fed through the flap 23 on top of the glowing layer of sawdust into the zone of glowing olilok, and the rest of the air (10%) is fed through the flap 24 under the grate, and smoke occurs.

Simultaneous cooling

top layer of sawdust and eliminates the possibility of ignition. When the set temperature of smoke is exceeded, the thermostat Tar 9 and water automatically trigger

at the same time comes through sprayers 8 and 15.

From the smoke chamber, smoke is continuously sucked by the fan 16 through the filters 13 and 14 of the smoke chamber and supplied to the resin separator 17, the electrostatic filter 18 and, if necessary, the heater 19, where the smoke is cleaned from mechanical impurities, free tar and 3,4-benzpyrene.
