Problems solved by technology

For most of the self-built incinerators of medical institutions, they contain a large amount of hazardous waste, which is very easy to produce highly toxic substances such as dioxin during the combustion process, and there is currently no reasonable way to properly dispose of some medical waste liquids, which accumulates over time It will cause a huge threat and damage to human health and the ecological environment. In summary, the existing hazardous waste treatment process needs to be separated and treated, which is cumbersome and inefficient. It is difficult to achieve effective melting and non-toxic discharge. At the same time The fire stability of the treatment device is not high and the heat energy utilization rate is poor

specific Embodiment approach 1

[0023] Specific implementation mode one: combine figure 1 , figure 2 , image 3 with Figure 4 Describe this embodiment, this embodiment comprises vertical combustion cylinder 3, horizontal combustion cylinder 7, reciprocating fire grate 1 and a plurality of temperature raising burners 2, and described vertical combustion cylinder 3 is vertically arranged, and vertical combustion cylinder 3 The top is the inlet end of fine-grained hazardous waste, and the inside of the vertical combustion tube 3 is a vertical combustion furnace, which is sequentially processed with a plurality of top burn-off air nozzles 4, a plurality of primary air nozzles 5 and A plurality of secondary air nozzles 6, the horizontal combustion cylinder 7 is obliquely arranged below the vertical combustion cylinder 3, the high end of the horizontal combustion cylinder 7 communicates with the bottom end of the vertical combustion cylinder 3, and the horizontal combustion cylinder 7 is connected to the botto...

specific Embodiment approach 2

[0055] Specific implementation mode two: combination figure 2 , image 3 , Figure 5 with Figure 6 To describe this embodiment, in this embodiment, a plurality of split burn-off air nozzles 15 are also processed on the cylinder wall of the vertical combustion cylinder 3 . This setting cooperates with multiple top burn-off air nozzles 4, multiple primary air nozzles 5 and multiple secondary air nozzles 6 to ensure that the four corners are tangentially circled and generate strong swirling flow, so that the vertical combustion tube 3 can fully burn High melting point characteristics.

[0056] It is feasible for the present invention to reach the temperature condition for melting hazardous wastes without adding auxiliary fuel, but some auxiliary means are needed. The calculation results show that the effect of increasing the furnace temperature by controlling the lower air excess coefficient is very limited. And increasing the air distribution ratio of primary air and seco...

specific Embodiment approach 3

[0058] Specific implementation mode three: combination figure 1 Describe this embodiment, in this embodiment, the end of the first discharge passage 10 communicating with the horizontal combustion tube 7 is set toward the bottom of the vertical combustion tube 3 . In this embodiment, the arrangement of the first discharge channel 10 and the horizontal combustion cylinder 7 in such a position can ensure the smooth discharge of ash and melt produced by the horizontal combustion cylinder 7, shorten the discharge path, reduce the processing time, and improve the processing efficiency. Other unmentioned structures and connection methods are the same as those in the first or second embodiment.

Abstract

The invention discloses a fusion device capable of simultaneously treating polymorphic hazardous wastes, and relates to a fusion device. The existing solid or liquid hazardous wastes need classified treatment, and the treatment process is complicated, difficult to realize the effects of effective fusion and non-toxic discharge, low in ignition stability and bad in heat energy utilization rate. The top end of a vertical combustion chamber is an inlet end for thin-particle size hazardous wastes; the interior of the vertical combustion chamber is a vertical combustion hearth; a horizontal combustion chamber is arranged below the vertical combustion chamber in an inclined manner; the high end of the horizontal combustion chamber is communicated with the bottom end of the vertical combustion chamber; a first discharging channel and a second discharging channel are formed in the horizontal combustion chamber in sequence; the interior of the horizontal combustion chamber is a horizontal combustion hearth; the interior of the horizontal combustion chamber is divided into a preliminary fusion chamber and a thermal insulation warming chamber in sequence; a reciprocating grate is arranged in the preliminary fusion chamber; and a plurality of warming combustor are arranged in the thermal insulation warming chamber. The fusion device disclosed in the invention is used for treating hazardous wastes.

Description

technical field [0001] The invention specifically relates to a melting device capable of simultaneously processing multi-form hazardous waste. Background technique [0002] In recent years, both the public health impact and the transboundary movement of hazardous waste have continued to be hot topics around the world. As one of the developing countries with the fastest GDP growth rate, our country is also facing the problem of hazardous waste. Environmental accidents and hazards caused by hazardous waste often last for a long time, are highly concealed, and have serious consequences; once a pollution accident occurs, environmental pollution control will cost a huge amount of money, and ecological restoration will take longer, and sometimes it is even difficult to restore. Therefore, it is a key issue to strengthen the management of hazardous waste and realize the harmless treatment of hazardous waste. [0003] Hazardous waste mainly involves three areas: industrial hazardo...
