Combined type incinerating device capable of controlling toxic gases and heavy metal content in waste incineration smoke

Abstract

Provided is a combined type incinerating device capable of controlling toxic gases and heavy metal content in waste incineration smoke. An incinerator hearth is composed of a first combustion chamber and a second combustion chamber, the first combustion chamber is a horizontal type combustion chamber, the second combustion chamber is a vertical type combustion chamber, heat insulation type combustion chambers are adopted by the whole first combustion chamber and the second combustion chamber of enough height, multiple primary air inlet chambers are adopted by the first combustion chamber to carry out chamber division and amount selected air supply according to needs, two rows of secondary air exhaust pipes which blow oppositely and are arranged at the connecting positions of the other two combustion chambers blow in secondary air, slaked lime adding devices are arranged out of the hearth at the horizontal height of the center of an upper boiler barrel and the hearth of the horizontal height at the center of a lower boiler barrel of a double-boiler-barrel vertical type waste heat boiler, and the slaked lime adding devices inject quantitative slaked lime into the hearth in the flow direction of the high temperature smoke between the upper boiler barrel and the lower boiler barrel. According to the combined type incinerating device capable of controlling the toxic gases and the heavy metal content in the waste incineration smoke, the structural characteristics of the combined type incinerating device is utilized, the controlling over all techniques and parameters is combined, source controlling over the toxic gases and heavy metal is achieved in an incineration process, the pressure of tail gas purification work is relieved fundamentally, and market needs are met.

Description

technical field [0001] The invention relates to the technical field of waste incineration, in particular to a combined incineration device capable of suppressing the content of toxic gases and heavy metals in waste incineration flue gas. Background technique [0002] In the context of increasingly stringent global air pollution requirements, my country has done a lot of work on exhaust gas purification for waste incineration. Introduced and developed a variety of related technologies and equipment. However, the existing technologies and equipments have many problems such as the exhaust gas purification rate is not up to the standard, and the investment and operation costs are expensive. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a combined incineration device capable of controlling the content of toxic gases and heavy metals in waste incineration flue gas from the source in view of various problems existing...
