Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
Detailed Description
In order to make the aforementioned and other features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
As shown in figure 1, the hazardous waste incinerator device using natural gas comprises an incinerator body 1, wherein a primary air chamber 2 is arranged at the bottom of the incinerator body, a combustion chamber is arranged at the upper part of the incinerator body, the primary air chamber is communicated with the combustion chamber through a plurality of air caps 3, a natural gas combustor 4 is arranged in the primary air chamber, and a discharging pipe 5, a coal discharging pipe 6 and a smoke discharging pipe 7 are arranged on the side part of the combustion chamber. The discharging pipe is used for conveying dangerous wastes such as oil sludge, sludge and the like to be incinerated, and the discharging pipe is used for conveying auxiliary fire coal.
In the embodiment of the utility model, the lateral part of the primary air chamber is provided with a primary air inlet 8, and the natural gas burner is provided with a natural gas inlet 9.
In the embodiment of the present invention, the combustion chamber is composed of a bottom dense phase zone 10 of the incinerator and a top dilute phase zone 11 of the incinerator.
In the embodiment of the present invention, a plurality of temperature control thermocouples 12 are disposed around the dense phase region of the incinerator.
In the embodiment of the present invention, the periphery of the dilute phase zone of the incinerator is provided with a secondary air inlet 13.
In the embodiment of the utility model, the blanking pipe and the coal blanking pipe are both located at the periphery of the dense phase area of the incinerator, and the smoke exhaust pipe is located at the periphery of the dilute phase area of the incinerator.
In the embodiment of the utility model provides an in, the pipe of discharging fume is equipped with waste heat utilization system 14, flue gas processing system 15, chimney 16 along the flue gas direction in proper order. The waste heat utilization system and the flue gas treatment system are both in the prior art.
The working principle of the hazardous waste incinerator device using natural gas is as follows: the hot air of natural gas combustion is added into a combustion chamber through a blast cap of combustion-supporting primary air (the blast cap needs to be replaced by a high-temperature resistant blast cap, and the wall of the primary air chamber needs to be high-temperature resistant), thermocouples are arranged at different parts of a dense-phase area of the incinerator, the load of the burner is controlled according to the temperature feedback of the dense-phase area of the incinerator, and the temperature stability of the waste such as oil sludge in the incinerator is ensured during incineration. When natural gas is used as auxiliary fuel, the supply of auxiliary fuel coal can be stopped, and in the process of incineration, in order to avoid the situations of insufficient bed material and uneven heat exchange, partial bed material (with the grain diameter of 10-20 mm) can be conveyed to an incinerator through a coal feeding pipe or a small amount of fuel coal can be fed intermittently. After the dangerous waste enters the dense-phase area of the incinerator, the dangerous waste exchanges heat with natural gas burning hot air entering from a blast cap to be burned, the smoke enters the dilute-phase area of the upper incinerator, the smoke is fully burned out under the action of secondary air in the dilute-phase area of the incinerator, and the high-temperature smoke enters the waste heat utilization system and the smoke treatment system at the rear part and then is discharged through a chimney up to the standard.
The present invention is not limited to the above preferred embodiments, and any one can obtain other various types of hazardous waste incinerator devices using natural gas according to the teaching of the present invention. All the equivalent changes and modifications made according to the claims of the present invention shall fall within the scope of the present invention.
