Description

The utility model relates to the field of waste disposal, in particular to the thermal processing of waste, and can be used in the household and industry.

Known devices for thermal processing of waste, containing a combustion chamber and an afterburner with fuel blast nozzles and air blast nozzles, a loading window with a door, a chimney (see RF patent No. 2087803, according to IPC F23G 5/00, publ. 03.08.1995, patent Russian Federation No. 2117871, according to IPC F23G 5/00, published on 08/20/1998, RF patent No. 2476771, according to IPC F23G 5/00, published on February 27, 2013.

The closest in technical essence is a device containing a combustion chamber with a combustion chamber and an afterburning chamber, fuel blast nozzles and air blast nozzles, a loading window with a door, a vertical chimney, and at least one nozzle and a vertical chimney for the exit of gaseous combustion products from the lower part of the combustion chamber to its upper part, while the chimney in the upper part of the combustion chamber is located so that the torch of the nozzle installed above the combustion chamber covers the entire flow area of the flow of gaseous combustion products, the nozzle, located in the lower part of the combustion chamber, is installed at an angle of 3-5° to the horizon, the chimney, which ensures the exit of gaseous products of combustion from the lower part of the combustion chamber, is formed by a pipe barrier between the walls of the combustion chamber and the combustion chamber, in the lower part of the combustion chamber there is a closable sunroof for ash discharges (see RF patent No. 2117871, according to IPC F23G 5/00, publ. 08/20/1998.).

The disadvantage of the known device is the low intensification of the combustion process, the device is limited in its applicability, the loading of waste is carried out from above, therefore, when loading waste, it is necessary to use loading devices.

The technical result is to increase the intensity of combustion.

The technical result is achieved by the fact that in a device for thermal processing of waste, containing a combustion chamber with a lower fuel blast nozzle and lower air blast nozzles, an afterburner with an upper fuel blast nozzle and an upper air blast nozzle, a loading window with a furnace door, a vertical chimney, according to of the useful model, the afterburner chamber is cylindrical in shape and is located on the plane of the combustion chamber overlap above the outlet, made with the possibility of the passage of gaseous combustion products with unburned particles, the loading window is located in the lower part of the combustion chamber with the possibility of loading garbage and waste directly onto the bottom surface of the combustion chamber, the lower fuel blast nozzle of the combustion chamber is located with the possibility of blowing the flame of the burner torch at an angle of 45 ° relative to the wall of the combustion chamber, the upper nozzle of the fuel blast of the afterburning chamber is located with the possibility of blowing the flame of the burner torch ki in the tangential direction. The vertical chimney is made cylindrical and is located coaxially with the afterburner.

The essence of the utility model is illustrated by a drawing, which shows a general view of the proposed device. The device for thermal processing of waste includes a combustion chamber 1 with a lower fuel blast nozzle 2 and lower air blast nozzles 3, an afterburner 4 with an upper fuel blast nozzle 6 and an upper air blast nozzle 5, a loading window 7 with a furnace door 8, a vertical chimney 9, made in two steps. The afterburner 4 is made cylindrical and is located above the combustion chamber 1. The lower fuel blast nozzle 2 is located at an angle of 45° relative to the wall of the combustion chamber.

The device is equipped with an automatic control system that controls the operation of the burners, the electromagnetic protection of the furnace door, and the maintenance of the set temperature in the chambers. The proposed device works as follows.

Waste through the loading window 7 with the furnace door 8 open is loaded onto the surface of the bottom of the combustion chamber 1, where it is burned by blowing the flame of the lower fuel blast nozzle 2.

The resulting gaseous products with elements of toxic substances from the combustion chamber 1 enter the afterburning chamber 4 for complete combustion and enter the torch of the upper nozzle of the combustible blast 6. Air is supplied to the combustion chamber 1 and the afterburner 4 through the lower air blast nozzles 3 and the upper air blast nozzle 5, communicating with blower fans (not shown in the drawing). Flue gases are removed from the afterburner chamber 4 through a vertical chimney 9. After complete combustion of the waste, the supply of combustible blast and air blast is turned off, the furnace door 8 is opened, and through the loading window 7, the burnt waste in the form of ash is removed from the surface of the bottom of the combustion chamber 1 with a scraper.

Then a reload is performed, and the cycle of work is repeated.

Depending on the type of waste, flue gases after the vertical chimney can be sent to the system for additional gas cleaning, combustion and afterburning chambers can have several fuel blast nozzles and air blast nozzles.

The proposed device allows the loading of waste through the loading window 7, and not from above through the hatch as in the known analogues, which makes it possible to load waste both using loading devices and manually.

The proposed device allows you to increase the efficiency of combustion, ensuring complete combustion of waste, improve reliability and reduce operating costs.
