The invention relates to environmental protection and can be used for thermal neutralization of solid waste in various sectors of the economy. The waste incinerator comprises a combustion chamber with a lower and upper working compartments, a casing to which a waste connection and a flue gas outlet are connected. The introduction into the combustion chamber of the middle working compartment, the grate forming the boundary between the middle and lower working compartments, and the diaphragm installed between the middle and upper working compartments, and the inclusion of a vortex cyclone chamber in the lower working chamber, and at the same time supplying the waste pipe and path connection Discharge of flue gases into the middle working compartment and the output from the upper working compartment, respectively, allows the separate process of preparation of a high-temperature working medium for gasification, the actual gasification process and the afterburning process and thermal neutralization of gasification products, and thus improve the reliability of solid waste disposal. In addition, the presence of separate chilled channels for each compartment ensures efficient separate cooling of the three working compartments and, accordingly, further improves the reliability of waste disposal.
DESCRIPTION OF THE INVENTION
The invention relates to environmental protection and can be used for thermal neutralization of solid waste in various sectors of the economy.
A furnace for thermal neutralization of solid waste is known, characterized by increased detoxification efficiency. However, the furnace is rotary, which complicates the device as a whole (SU, copyright certificate, 1818506, cl. F 23 G 5/00, 1990).
The closest in technical essence to the proposed solution - its prototype is a waste incinerator containing a vertically located chamber with a lower and upper working compartments, a casing to which a waste feed pipe, a flue gas outlet and an air supply line to the working compartments that are connected Are connected to each other by a passage pipe, passing into the branch pipe, inside which the rod is located. The disadvantage of the solution is the lower reliability of solid waste disposal (SU copyright certificate 1663320, cl. F 23 G 5/00, 1989).
The object of the present invention is to provide an apparatus combining the relative simplicity of the structure with the increased reliability of thermal solid waste disposal.
The subject of the invention is a waste incinerating furnace having a vertically disposed combustion chamber with interconnected lower and upper working compartments, a housing to which a waste feed pipe, a flue gas outlet and an air supply line to the upper and lower working compartments are different, In that the combustion chamber comprises an average working compartment, a grate forming a boundary between the middle and lower working compartments, and a diaphragm installed between the middle and upper working compartments, at least one vortex cyclone chamber is included in the lower working compartment, The waste loading branch and the flue gas outlet are provided with an inlet to the middle working compartment and an outlet from the upper working compartment, respectively.
This set of characteristics allows us to divide three processes: preparation of a high-temperature working fluid for gasification; Actual gasification; Afterburning and thermal neutralization of gasification products and, thus, improve the reliability of solid waste disposal.
The invention has the development that the furnace is provided with a lower, middle and upper cooled channels located between the outer walls in the respective compartments of the combustion chamber and the internal surfaces of the respective parts of the casing, with an air supply connection to each cooled channel, The upper working compartment is made in the form of radial holes in its wall, and the line for supplying air to the lower working compartment is in the form of a path connecting this compartment and the vortex cyclone chamber with the lower cooled channel.
This allows for efficient separate cooling of the three working compartments and, correspondingly, in addition, to increase the reliability of waste disposal.
The essence of the invention is illustrated by the drawing, which shows the longitudinal section of the furnace.

The waste incinerator comprises a chamber 1 with a lower and upper working compartments 2 and 3, a casing 4 to which a waste loading pipe 5 and a flue gas outlet 6 are connected. In chamber 1, an average compartment 7 is allocated. The boundary between the compartments 7 and 2 forms a grate 8, and between the compartments 7 and 3 a diaphragm 9 is installed. The vortex cyclone chamber 10 is included in the compartment 2. The branch pipe 5 and the path 6 are provided with an inlet 11 in the compartment 7 and an outlet 12 from the compartment 3, respectively. The furnace is provided with a lower, middle and upper cooled channels 13, 14, 15 located between the outer walls of the compartments 2.7 and 3 and the internal surfaces of the respective parts of the housing 4. An air supply connection 16 is connected to each of the channels 13, 14, 15. In this case, the air supply line from the duct 15 to the compartment 3 is made in the form of radial holes 17 in the wall of the compartment 3, and the air supply line to the compartment 2 is in the form of a path 18 connecting the compartment 2 and the vortex cyclone chamber 10 to the channel 13. The furnace is also equipped with a device 19 for removing ash. The figure shows the execution of the diaphragm 9 in the form of a clamping. It is also possible to do it differently, for example, in the form of a steel or ceramic afterburning grate. |
The furnace operates as follows. In the chamber 10, for example, liquid fuel is supplied via line 20 and the air required for combustion from the duct 13 along the path 18. The combustion products of the fuel are mixed in the compartment 2 with air coming from the duct 13 along the path 18 and form a high temperature gas For warming up and gasification of the waste loaded through a branch pipe 5 on a lattice 8 of a compartment 7.
Waste gasification products come from the compartment 7 through the diaphragm 9 to the compartment 3 where they mix with the air coming through the hole 17 and burn. The flue gases are discharged through the duct 6. The walls of the chamber 1 are cooled by air, supplied to the channels 13, 14 and 15 through the pipes 16.
The presence of three compartments 2,3 and 7 in the combustion chamber 1 makes it possible to separate the process of preparation of a high-temperature working medium for gasification, the actual gasification process and the afterburning process and thermal neutralization of gasification products, and the availability of independent cooling channels for each compartment ensures reliable and economical operation of the furnace , Which in general, accordingly, raises the reliability of solid waste disposal.
