Abstract

The invention relates to a device for the fire disposal of wastewater, mainly wastewater from the production of urea-formaldehyde resins, and the burning of wood dust in woodworking enterprises. The purpose of the invention is to increase reliability and efficiency. In the installation containing a vertical cyclone furnace 1 with a pinch 2 and a gas duct 3 under it, the gas duct is made in the form of a bath and connected to the waste water pipeline 4, and in the lower part of the duct outlet 3, along its entire width, a slit air nozzle 7 is installed, configured to rotation around the horizontal axis. In the duct 3, during operation of the installation, the waste water is heated and reclaimed by liquid slag. The effluent vapors are intensively mixed with air flowing from the slit air nozzle 7, which causes the burning of toxic substances. The ability to rotate the slit air nozzle 7 makes it possible to select the optimal burning conditions depending on the amount of effluent and the content of toxic substances in them. 2 Il.

substances in the particles of wood drink. At this temperature, due to the interaction of wood ash and abrasive plastics, a shpak is formed, which in the form of droplets under the influence of centrifugal forces is separated on the inner walls of the cyclone furnace 1, and then flows down through pinch 2 into the duct 3, into the wastewater. Sewage water is supplied by the pump 12 to the heat exchanger 11, where it is heated by the heat of the waste combustion products to a temperature of: - 80 ° C tours, before it goes through

This water contains a vertical cyclone duct 4 that enters the gas duct 3. In the ganna furnace 1 with pinch 2 gas duct 3 under it. The duct 3 is made in the form of baths and is connected to the pipeline 4 - supply of waste water. In the upper part of the cyclone furnace 1, the burner device 5 and the wood-feed nozzle 6 are tangentially mounted. At the lower part of the exit of the duct 3, an air nozzle 7 is installed along its entire width, made with the possibility of a gate relative to the horizontal axis. A hatch 9 is used to remove particles of the granulated spit 8, the Flue 3 is connected to the steam generator 10, in the tail part of which a heat exchanger 11 is located. The pump 12 is designed to supply waste water.

The installation works as follows.

Through the burner 5, fuel is supplied, for example, natural gas, which, as a result of combustion, forms a swirling high-temperature flow. Combustion products are successively passed through 20

In waste 3, the waste water is again heated and evaporated along with the toxic substances due to the liquid slurry falling into it from above. After cooling, the ptak is granulated into solid particles, which are periodically removed from the plant through a hatch 9.

Combustion products of wood drink, water vapors and vapors of toxic substances at the exit of the duct 3 are mixed with air, which flows out of a slotted air nozzle 7. At the same time, high-intensity burning of toxic substances occurs in the furnace of the steam chamber Og.

Turning the slit air nozzle 7 around the horizontal axis, select the optimum conditions for mixing air and toxic substances depending on the amount of waste water to be disposed of, and on the concentration of toxic substances in it, which causes high-quality burning of toxic substances.

cut the clamp. 2, the flue 3, the combustion steam generator-40 in the steam generator 10, uses 10, from which they are released into the atmosphere.

Then, using pump 12, pipeline 4 supplies waste water to the gas duct 3, and air to the slot-type loader 7.

After the internal walls of the vertical cyclone furnace reach the temperature, through a nozzle 6 at a speed of .80 m / s, a mixture of air and wood is fed tangentially, which ignites and, when burned, forms a high temperature swirling flow. After the temperature of the combustion products reaches 1300 C, the supply of fuel through the burner 5 stops,

At 1300 ° C, toxic gases are burned out, which occur during TepMK iecKOM decomposition into the living

It is used to generate steam and to heat waste water in a heat exchanger 11.

Due to the fact that the flue duct is in the form of a bath and connected to the wastewater supply pipeline, it always contains a certain amount of wastewater that heats and evaporates along with the current of sewage substances due to the liquid scrap that falls into the wastewater.
