Embodiment Construction

[0028] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0029] Such as figure 1 As shown, the alternate motion grate waste incinerator includes a furnace arch 1, a refractory brick platform 2, a feed pusher 3, a fire grate 14, a slag discharge device 23, a drying chamber 24, a combustion chamber 25 and an ember chamber 26 .

[0030] The furnace arch 1 is an arched structure, located above the drying chamber 24, the combustion chamber 25 and the ember chamber 26, and forms a closed cavity with the drying chamber 24, the combustion chamber 25 and the ember chamber 26.

[0031] The feed pusher 3 is arranged on the left side of the refractory brick platform one 2, and the amount of garbage entering the furnace is controlled by the feed pusher 3 .

[0032] Described fire grate 14 is divided into three levels, is set as fire grate one, fire grate two and fire grate three, and the fire grate of each leve...

Abstract

The invention relates to the field of garbage incineration, and in particular, discloses an alternating motion type fire grate garbage incineration furnace. The incineration furnace adopts an alternating motion type fire grate scheme; two adjacent rows of fire grate pieces are in an alternate reciprocating motion, so that loose, uniform and continuous rolling of garbage on the fire grates is guaranteed, and the garbage combustion speed is accelerated; the fire grate pieces are arranged in exhaust ports of different combustion areas to form different angles with a horizontal plane, so that theexhaust flowing speeds and directions in different combustion areas are different, and continuous and efficient combustion, burnout and discharge of the garbage and ash are guaranteed; and a furnace arch is provided for guaranteeing a drying effect of high-temperature smoke on garbage just fed in the furnace, so that the stop time of the high-temperature smoke in a hearth is prolonged, and the effects of drying the garbage in the inlets, burning all garbage residues and balancing the hearth smoke speed and a temperature flowing field are achieved.

Description

technical field [0001] The invention belongs to the field of garbage incineration, and in particular relates to an alternate motion grate garbage incinerator. Background technique [0002] With the development of urbanization, the problem of urban garbage siege has become increasingly prominent. At present, domestic waste treatment devices mainly include rotary kiln, fluidized bed and grate furnace. Among them, grate furnace is the most widely used, but the current grate technology has not been completely solved. Garbage ash and slagging are serious, the local temperature of the grate is overheated, and the local wear and corrosion of the grate is serious. Contents of the invention [0003] The object of the present invention is to provide an alternately moving grate garbage incinerator, which can effectively solve the problems of serious ash accumulation and slagging of garbage, excessive local temperature of the grate and severe local wear and corrosion of the grate. ...
