Garbage incineration device

Technical Field

The invention belongs to the technical field of garbage treatment, and particularly relates to a garbage incineration device.

Background

In daily production and life, a lot of garbage is generated, one method for treating the garbage is to adopt traditional incineration, and in order to recycle energy, the existing garbage incineration is used for generating electricity. Present rubbish is when burning, and the moisture content is too high, and rubbish is fluffy, and area is big, is not convenient for transport the burning of concentrating in the incinerator, and current partial rubbish compressor arrangement is not enough to rubbish compression degree, and is difficult to take out again and transport rubbish when the compression is sufficient, and especially when compressing rubbish in succession, rubbish often can block up in the compression passageway, will be or not exactly the passageway sets up unreasonablely, leads to the compression degree not enough. In addition, the generated smoke dust needs to be treated during incineration so as to ensure reasonable environmental protection emission standard. At present, the dust burnt is captured and collected by a filter screen in a filter chamber, but during waste incineration, smoke dust is very large, and dust generated after flying waste incineration needs to be collected by primary separation so as to improve the collection rate of dust and collect dust more fully. However, when dust is collected after the current garbage incineration, the dust enters the filter chamber at one time due to too much dust, the filter screen is easily blocked, especially the garbage is various, when the comprehensive garbage in various channels such as industry and life is covered, the particle dust types contained in the smoke are also very widely distributed, part of the flame-retardant residues which are difficult to filter are bound to block the filter screen, and the particle dust generated by the rest of the garbage incineration can not be captured and filtered, so that the problem of how to better extract the corresponding dust particles is also solved under the condition.
