Description

A mobile waste heat utilization waste incineration system

technical field

The invention belongs to the technical field of garbage incinerators, and in particular relates to a movable waste heat utilization garbage incineration system.

Background technique

According to the National Environmental Protection Agency, the number of fire spots in various cities is closely related to the air quality, which reveals that open-air burning is a major culprit of air pollution, and open-air burning of garbage is even more harmful. According to data, the dioxins produced by open-air incineration of garbage are 2000-3000 times the dioxins emitted by modern garbage incinerators. The study found that there are at least 20 kinds of harmful pollutants discharged into the atmosphere by open burning of garbage, including well-known benzene, acetone, polycyclic aromatic hydrocarbons, chlorobenzene, dioxins, furans, polychlorinated biphenyls, PM ₁₀ (atmospheric Particulate matter with a diameter of less than 10 microns, also known as inhalable particulate matter or floating dust), PM _2.5 (particulate matter with a diameter of less than or equal to 2.5 microns in the atmosphere, also known as particulate matter that can enter the lungs) and volatile organic compounds. The ash produced by incineration is also rich in dioxin-like pollutants and heavy metals, such as lead and chromium. In addition, garbage also contains a large amount of heavy metals and nitrates, which will enter the ground with rainwater, polluting soil and groundwater.

Due to the large investment and complicated operation of the large-scale waste incineration plant project, it takes a lot of manpower and material resources, has high requirements for equipment, and is resisted by local residents, so it is impossible to invest heavily in the construction of the plant.

Although the above-mentioned technologies can improve the efficiency of waste incineration, they all have the disadvantages of large equipment, high cost, and low efficiency of pollutant control, and cannot effectively solve the problem of open-air incineration of waste. It is urgent to design a convenient incinerator that can solve the problem of open-air waste The problem of incineration can be effectively utilized and the waste heat generated by combustion can be effectively treated and the smoke and gas pollutants produced can be efficiently treated.

detailed description

The specific content of the present invention will be described in detail in conjunction with the accompanying drawings. A mobile waste heat utilization waste incineration system, comprising a furnace body 1, a combustion chamber 2 arranged inside the furnace body 1, a water tank jacket 3 and a smoke exhaust device 4, wherein the bottom of the furnace body 1 is provided with wheels 5, and the combustion chamber The front middle part of the 2 is provided with a garbage filling port 6, and a plurality of air intake holes 7 are evenly distributed on the combustion chamber 2 outside the garbage filling opening 6. The top of the rear side is provided with a smoke outlet, the bottom of the combustion chamber 2 is provided with a slag and ash outlet 9, the outer side of the combustion chamber 2 is provided with a sealed water tank jacket 3, and the outer side of the water tank jacket 3 is provided with a rock wool insulation layer A furnace door is provided on the furnace body 1 opposite to the garbage filling port 6 of the combustion chamber 2, the smoke exhaust port of the combustion chamber 2 communicates with the outside atmosphere through the smoke exhaust device 4, and the upper part of the water tank jacket 3 is connected with a The outer water inlet pipe 10 and the lower part of the water tank jacket 3 are connected with an outlet pipe 11 extending to the outside of the furnace body 1. The outlet pipe 11 is provided with a valve 12. The smoke exhaust device 4 consists of a chimney 13 and a cloth bag arranged inside the chimney 13. Dust collector 14 and activated carbon filter 15 are formed, and the bottom of chimney 13 is provided with ash collecting device 16, and this ash collecting device 16 is connected with slag and ash outlet 9, and the smoke inlet in the middle of chimney 13 is connected with combustion chamber through smoke exhaust pipe 17. The smoke outlets of the chamber 2 are connected, and the top of the smoke inlet in the chimney 13 is provided with a bag filter 14 and an activated carbon filter 15 in sequence.

The present invention designs the incineration system as a common kiosk style, and the combustible garbage enters the combustion chamber through the garbage filling port, and adds combustion aids, and the air can be sucked into the combustion chamber by the blower and the air intake hole to provide air for garbage incineration. After the waste is incinerated, the smoke and dust generated are discharged into the smoke exhaust device through the smoke exhaust pipe. The smoke exhaust device is equipped with a bag dust collector and an activated carbon filter that absorbs harmful gases (dioxins). The efficiency of bag dust removal can reach more than 99%. The clean flue gas is discharged from the top of the chimney. The jacket of the water tank uses pure water to enter from the water inlet pipe. The pure water absorbs the heat generated by the combustion of garbage in the combustion chamber in the jacket of the water tank, and flows out from the outlet pipe after heating up. This measure can solve the problem of drinking water for sanitation workers in winter. To achieve the purpose of waste heat utilization. The waste slag and smoke generated by the garbage combustion are discharged from the slag and dust outlet.

The operation process of the present invention is: when preparing to burn the garbage, put the garbage into the combustion chamber from the garbage filling port on the side of the device, and then burn the fuel and the garbage. The air required for the combustion of garbage in the combustion chamber is drawn into the evenly distributed air holes by the blower connected to the air inlet, and enters the combustion chamber. The combustion chamber is surrounded by a water tank jacket, and the pure water in the water tank jacket enters from the water inlet pipe. The heat of garbage combustion is absorbed by the pure water in the water tank jacket. When the outlet pipe valve is opened, the heated pure water flows out from the outlet pipe. . The smoke and dust generated by the garbage burned in the combustion chamber is passed into the smoke exhaust device through the smoke exhaust pipe, and the particulate matter in it is removed by the bag filter, and the removed particulate matter enters the ash receiving device and is cleaned out through the slag outlet. The dust from the removal of particles needs to pass through a chimney containing an activated carbon filter because it also contains harmful gases, and is discharged into the atmosphere after being adsorbed by activated carbon.

The basic principles, main features and advantages of the present invention have been shown and described above. On the premise of not departing from the spirit and scope of the present invention, the present invention also has various changes and improvements, and these changes and improvements all fall into the claimed invention. range.
