Two-section type waste incinerator

Abstract

It is disclosed a two-section type waste incinerator, wherein secondary air supplying holes (27e) are provided on a front arch and a back arch of an incinerator body (27), and an ignition combustion-supporting hole (27f) is provided on the back arch of the incinerator body. Grate inside the incinerator body (27) is divided into two sections from a high point to a low point, i.e., an upper section and a lower section, the upper section is a pusher type section (6) and the lower section is a reverse pusher type section (7), and an independent primary air chamber (26) is provided under each section. All heads of the grate-pieces (3, 5) on the pusher type section (6) face toward a low point of the grate, and all heads of the grate-pieces (3, 5) on the reverse pusher type section (7) face toward a high point of the grate. Each movable beam (4) on the same section of the grate is equipped with left and right levers (24, 25) disposed side by side, the left and right levers (24, 25) are supported by a supporting roller device respectively and are connected to the movable beam (4) to form a lever frame, and an end of the lever frame is connected to a front swing arm driving mechanism or a lateral swing arm driving mechanism or a front straight driving mechanism. The incinerator of the present invention can realize sufficient dryness, complete combustion and burnout of the whole waste layer, and ensure the desired waste incineration effect and ignition loss.

Description

FIELD OF THE INVENTION

[0001] The present invention belongs to a field of solid waste incineration processing technology, in particular relates to a municipal solid waste incinerator or namely a municipal household waste incinerator.BACKGROUND OF THE INVENTION

[0002] The existing waste processing technologies mainly include incineration, sanitary landfill, compost, waste recycling, etc. In these common waste processing technologies, the incineration process has the advantages of reducing the gross of the waste remarkably, being harmless thoroughly, occupying small land, utilizing waste heat and minimizing secondary pollution, etc., which comply with the strategy of sustainable development of our country.

[0003] In the existing incineration processes and devices, there are various forms of grate-typed incinerators, the application of which occupies more than 80% of the total amount of waste incineration market all over the world. In one type of incinerator, all grates in the incinerator bo...

first embodiment

The First Embodiment

[0062]As shown in FIG. 1, a slag removing port 27a is provided at a tail portion of a bottom end of an incinerator body 27, a material feeding bunker 27b is provided at a front portion of a top end of the incinerator body 27 and a smoke outlet 27c is provided at a rear portion of the top end of the incinerator body 27. A smoke passing hole adjacent to the smoke outlet is provided on the upper portion of a rear wall of the incinerator body 27, and an inner cavity of the incinerator body 27 is communicated with a smoke detection means provided outside of the incinerator body through the smoke passing hole. Secondary air supplying holes 27e are provided on a front arch and a back arch of an incinerator body 27, a secondary air supplying device provided outside of the incinerator body is communicated with the inner cavity of the incinerator body 27 through the secondary air supplying holes 27e, and an ignition combustion-supporting hole 27f is provided on the back ar...

second embodiment

The Second Embodiment

[0074]As shown in FIG. 12, in the embodiment, the lever frame of the pusher type section 6 is driven by a front swing arm driving mechanism, the lever frame of the reverse pusher type section is driven by a front straight driving mechanism. The front straight driving mechanism comprises a driving cylinder 11, a driving cylinder seat 12 and a straight driving linkage 19, wherein the cylinder body of the driving cylinder 11 is hinged to the driving cylinder seat 12, a piston rod of the driving cylinder 11 is hinged to one end of the straight driving linkage 19, the other end of the straight driving linkage 19 is connected to the corresponding lever frame. Other structures of the embodiment are the same as the first embodiment, and thus are unnecessary to be described in details here.
