Partition cavity type small-sized rubbish pyrolysis and gasification incinerator

Abstract

The invention discloses a partition cavity type small-sized rubbish pyrolysis and gasification incinerator comprising a hopper, a gate, a drying cavity, an upper fire grate, a combustion hearth cavity, a lower fire grate and a secondary combustion chamber. High-temperature smoke in the secondary combustion chamber is guided into a pyrolysis gasification cavity. A part of high-temperature smoke flows upward into the drying cavity to dry rubbish, generated steam is guided into a condensation liquefying tank to be liquefied through a steam suction cavity, odor flows back into the combustion hearth cavity for high-temperature calcinations treatment, and smoke and the odor are prevented from escaping. The other part of high-temperature smoke flows downwards and is combined with heat generated by the combustion hearth cavity to form convection and radiation, rubbish is made to conduct pyrolysis and gasification at the same time, gasified gas flows out downwards from the upper fire grate to enter the combustion hearth cavity to be combusted, rubbish carbon overturned downwards by the upper fire grate is combusted on the lower fire grate, an opposite firing flame is formed between the upper fire grate and the lower fire grate, the gasified gas and pyrolyzed rubbish carbon form complementary combustion in the combustion hearth cavity, a durable high temperature keeping area enables dioxin type harmful matter to be decomposed, and heat energy generated by combustion is fully recycled.

Description

technical field [0001] The invention belongs to the field of garbage pyrolysis and gasification combustion furnaces (ie, incinerators), and in particular relates to a chamber-type small garbage pyrolysis gasification combustion furnace. Background technique [0002] With the improvement of people's living standards, more and more domestic garbage is produced in daily life, and the content of non-degradable components is also increasing, and the pollution to the environment is increasing day by day. The currently recognized best disposal method is centralized waste incineration for power generation, which has high investment costs and large processing capacity, and is generally used in large and medium-sized cities with large populations. For towns and vast rural areas with a small population and relatively low domestic waste production, long-distance transshipment is required, and the cost of infrastructure construction and transshipment is very high. [0003] Therefore, fo...
