Description

  The present invention relates to a pollution-free waste incineration structure, which is provided with a predetermined number of preheating devices around the furnace body to form a heat incineration operation on the waste in the furnace, and at the same time, a flue gas pipe at the top of the furnace body A flue is provided, and the flue gas line is further equipped with a blower and water curtain type circulation filter to efficiently filter toxic substances and off-flavors contained in waste incineration, achieving a pollution-free waste incineration function, and incineration Efficiently prevent exhaust from causing environmental pollution.

  Conventionally, approximately two kinds of methods have been adopted for waste disposal. One type is the landfill method, the other is the high temperature incineration method, the former does not require huge equipment costs, but it requires a vast landfill site, and this kind of landfill method has a bad odor. Not only is it likely to occur, it has caused serious environmental problems such as contamination of groundwater sources. For this reason, it is gradually replaced by the high temperature incineration method, which has become the mainstream of current waste disposal.

  Speaking of the high-temperature incineration system, the main condition is the construction and installation of an incinerator, and the incineration equipment incinerates the waste and collects and processes the waste as ash. There is no water source pollution problem, and the required land area is much smaller than landfill-type landfills, and it has gradually become a good option for waste disposal.

However, the following defects exist for incinerators that incinerate current waste at high temperatures:
1: To increase the thermal power during incineration of waste, it is necessary to introduce oxygen, it is easy to generate a large amount of black smoke and exhaust during combustion, and the toxic substances contained in the exhaust can be reduced efficiently. It is easy to cause air pollution.
2: Since high-temperature incineration of waste is adopted, the temperature of the furnace body and the surrounding environment becomes high, and burnout, burns, etc. are likely to occur, and there is a problem in safety.
Three: It is necessary to use a large amount of energy for combustion, the fuel cost of incineration is high, and the energy consumed at the same time is excessive, which greatly affects the economic effect of the treatment.
4: Regarding small private incinerators, the facilities lack capacity, often require repairs, and when burning and incinerating waste, it tends to develop into a fire with little carelessness.
5: The structural design of this type of incinerator is complicated and the overall equipment cost is high.

That is, the small incinerators of many of the private companies have the above-mentioned defects, and the large incinerators constructed by the government agencies have the effect of greatly reducing the quantity of waste by implementing garbage classification policies. However, due to high costs, the operation efficiency is low, the construction plan is not progressing, and it is essential to face the problem of waste disposal in the near future. An improved design is needed and we believe that solving the problem gives better practical value.

A plate region 32 and a drain valve pipe 321 are installed, and an additional burner 33 is mounted on the upper part of the separator plate region 32 according to the type of the waste 1 to be burned (if it is toxic waste, it is installed). And can be omitted if there is no toxic waste). The smoke exhaust pipe 30 is provided with a smoke exhaust pipe 331 having a predetermined length extending, and the smoke exhaust pipe 331 includes a heat-resistant blower 34 (the heat-resistant blower can adjust the air suction speed) and a water curtain circulation filter. The blower 34 introduces the exhaust gas generated by the combustion of the waste 1 in the furnace body 10 into the water curtain circulation filter 40. A plurality of layers of water discharge pipes 41 are placed inside the water curtain type circulation filter 40, a plurality of porous water leakage holes 411 are provided on the water discharge pipe 41, and a water storage tank 42 is provided at the bottom of the water curtain type circulation filter 40.

The waste 1 is transported to a plurality of water discharge pipes 41 placed horizontally inside, discharged from a plurality of porous water leakage holes 411 into a bottom layer (the number of layers can be designed as necessary) in a shower shape, and sucked by a blower 34. The exhaust gas generated by combustion is moderately purified. An exhaust pipe 47 is provided at the upper end of the water curtain type circulation filter 40 to exhaust the purified exhaust gas.

  When the waste 1 is put into the furnace body 10 and burned, the top plate 21 is opened by the handle 22 from the inlet 20 on one side of the furnace body 10, and when the waste 1 is put in, the lower door 23 is in a closed state. It is maintained so that dirty air, hot air, smoke, and odor in the furnace body 10 are not diffused outside. The upper door 21 is closed, the lower door 23 is opened by the handle 24, and the waste 1 is dropped into the furnace body 10. At this time, the furnace body 10 is not immediately ignited to burn the waste 1, After waiting for a certain amount of waste to accumulate, the waste is brought into contact with a preheating device 13 installed in the vicinity of the furnace body 10, and then the temperature of the preheating device 13 activated by the electric control system is increased, so that the internal waste 1 Combustion work is formed, and at the same time, an air / air supply device 12 (which may be a small fan, which can adjust the wind speed) in the intake hole valve 11 is activated to introduce the outside air and increase its combustion efficiency. At the same time, the exhaust generated by the combustion is sucked to the outside by the heat-resistant blower 34 of the flue gas line 30 on the one side of the furnace body 10, and the surroundings of the furnace body 10 around the blower 34 is in a starting operation. Air supply device 1 in the intake hole valve 11 Can select a stopped state or a state of continuous operation, and the outside air is slowly or rapidly introduced into the furnace body 10 so that the waste 1 in the furnace body 10 burns slowly or burns relatively slowly or When a state of rapid combustion is maintained and the exhaust gas is discharged out of the flue gas line 30, first, the moisture contained in the exhaust gas is separated via the vapor separator 31, and the detour channel inside the separator region 32 is bypassed. To achieve dust removal and waterproof function. A drain valve pipe 321 is installed on the outside, and high temperature (800 degrees or more) generated by the burner 33 efficiently burns toxic substances such as dioxin contained in the combustion exhaust (this step is not necessary if non-toxic substances). The exhaust gas exhausted is made into an exhaust gas that conforms to the environmental conservation standard, and then the combustion exhaust gas is introduced into the water curtain circulation filter 40 through the suction of the blower 34, and the water curtain pump performs the water curtain circulation filtration. The water in the water storage tank 42 at the bottom of the vessel 40 flows through the loop pipe 43 and the filter 44, and further through the water pump 45 to the circulation pipe 46. The water is transported to the water discharge pipe 41 and sprayed in the form of a shower from the plurality of porous water leakage holes 411 to the bottom layer (the number of layers can be designed according to actual needs). Curtain by adjusting the temperature of the exhaust, dissolved toxic substances such as dust contained simultaneously in water, filtering the contaminated with impurities toxic substances such as dust included in water by filter 44 at the same time. After use for a certain period of time, the filter material of the filter 44 is replaced or cleaned as necessary. The pollution-free exhaust gas treated by the water curtain circulating filter 40 can be discharged directly from the upper exhaust pipe 47, and the ash 2 generated after combustion of the waste 1 is ashed by the bottom grate 14 and the ash funnel inclined plate 16. The ash is taken out from the two cleaning ports 15 and 18 installed on the furnace body 10 after being divided into the accommodation space 19 and after a certain time. Thus, the simple work function of the pollution-free waste incinerator of the present invention is achieved.

  Several symmetrical vent hole valves 11 may be provided on the furnace body 10, and each vent hole valve 11 may not include the air supply device 12 and may be provided with a burner 33.
