Rubbish incineration and waste gas purification device and feeding machine thereof

Abstract

Provided is a rubbish incineration and waste gas purification device. A furnace body is provided with a water-injected interlayer filled with water used for temperature stabilizing, the furnace body is communicated with a hollow incineration grate at the bottom, a horizontal drying turning plate used for drying rubbish is additionally arranged in the furnace body, the drying turning plate and a sealing door are respectively of a cavity structure, and the drying turning plate is communicated with the water-injected interlayer through rotary connectors. Waste gas in the furnace body is exhausted through an exhaust duct, dust removal is conducted on the waste gas through a plurality of surge dust removing water tanks connected in series and a pair of water mist dust removing water tanks on the rear portion, lime water is arranged in the water tanks, isolation structures are arranged in the surge dust removal water tanks to enable the waste gas to pass through in a U shape on the water surface, and high-temperature surge foams are formed on the water surface. Spraying devices are arranged in the water mist dust removal water tanks for dust removal, an exhaust fan is arranged behind the water tank combination to enable air in the water tanks to be in negative pressure, and flow of the air is accelerated. The novel waste disposal equipment is environmentally friendly, capable of saving energy, free of pollution, low in furnace body temperature, long in service life, capable of conducting drying treatment on waste and sufficient in combustion, and the dust removal effect is excellent after the waste gas is treated through surge steam and mist spray.

Description

technical field [0001] The invention relates to a garbage incineration device for treating waste garbage by means of incineration, especially a garbage incineration and waste gas purification device for simultaneously dedusting and purifying the incinerated waste gas. machine. Background technique [0002] With the continuous strengthening of the society's awareness of environmental protection, waste disposal has become a hot issue. At present, the most efficient way to deal with waste is to incinerate waste with incinerators. The existing incinerators have the following disadvantages: using refractory bricks Or metal incinerator furnace body temperature is too high when working, long-term use is likely to reduce its service life due to overheating; at the same time, there is no pre-treatment of waste materials, waste materials contain moisture, and waste incineration after input The degree is uneven, the combustion efficiency is low, and the burner needs to be continuously...

[0002] With the continuous strengthening of the society's awareness of environmental protection, waste disposal has become a hot issue. At present, the most efficient way to deal with waste is to incinerate waste with incinerators. The existing incinerators have the following disadvantages: using refractory bricks Or metal incinerator furnace body temperature is too high when working, long-term use is likely to reduce its service life due to overheating; at the same time, there is no pre-treatment of waste materials, waste materials contain moisture, and waste incineration after input The degree is uneven, the combustion efficiency is low, and the burner needs to be continuously ignited, which consumes fuel and increases the cost of use; the exhaust gas of the combustion is only discharged into the air after being filtered by simple water and dust filter bags, and the purification efficiency is low. Particles below PM50 are filtered and purified, and the exhaust gas becomes a new source of pollution, so it cannot be close to the place of residence; at the same time, it is difficult to recycle the heat generated by incineration; in addition, because of the low efficiency of incineration and purification, there is also a common problem that the device is large in size , high manufacturing and maintenance costs, difficult to popularize and other problems, and if the heat energy generated by combustion is to be used, additional heat exchange pipes need to be laid, not only the project is complicated, but also the heat energy generated is not beneficial compared with the fuel oil consumed
