Description
Technical field
The utility model patent relates to a kind of novel grate furnace garbage incineration equipment, refers in particular to the reciprocating fire grate stove that a kind of two sections backsteppings add one section forwards project organization, and it is applicable to the burning disposal of the rubbish high for moisture content, that calorific value is low.
Background technology
Mechanical grate incinerator (following abbreviation mechanical kiln grate furnace) is long, the most most widely used type of furnace of developing history.Its application accounts for more than 80% of the whole world waste incineration total market size, the sharpest edges of such type of furnace are technology maturation, stable, reliable, wide adaptability, overwhelming majority solid refuse can directly advance stove without any need for pretreatment and burn, be particularly suitable for the characteristics that Chinese small and medium-sized cities msw water content is high, calorific value is low, be mainly used in large scale rubbish and focus on, the generating (or heat supply) of burning away the refuse.
Since the eighties in last century, along with Importing Foreign Advanced Technology and equipment, the application of China's grate furnace technology begins to popularize.The fire grate form of mechanical grate incinerator is a lot, mainly comprises rock type, step reciprocating formula, reserve motion formula, staged, crawler type, drum-type grate side by side, and having many is patent fire grates of overseas enterprise.For the characteristics of domestic waste, great majority adopt step reciprocating formula (forwards/backstepping) fire grate.The fire grate segment of reciprocating fire grate overlaps as roof sheet tile regularly, forms the supporter of incineration firing.The movable furnace grate plate that can seesaw and fixed grate film interleaved, its relative motion cause that rubbish is to forward and backward motion.Forms of motion according to rubbish on fire grate, fire grate can be divided into two kinds of pusher type and inverse-push.The direction of motion of its activity template of pusher type fire grate is consistent with the direction that rubbish advances in stove, and the activity template of inverse-push fire grate, the opposite direction that its direction of motion and rubbish are descending.
At present, domestic mechanical grate incinerator is mainly one-part form (i.e. one section forwards or one section backstepping) or two-period form (namely one section forwards+one section backstepping or two sections forwards or two sections backsteppings) and forms, when, calorific value high when moisture content in the rubbish composition is low, all exist drying garbage insufficient, stirring is easy conglomeration caking when breaing up not thorough and dry and burning, can't regulate according to the characteristic of rubbish well, and hot burn decrement rate can't be up to state standards.
Summary of the invention
The purpose of this utility model is to provide the reciprocating fire grate stove that a kind of two sections inverse-push add one section pusher type fire grate, it is applicable to burn the rubbish that moisture content is high, calorific value is low, traditional mechanical kiln grate furnace drying can be solved insufficient, the problem of stirring easy conglomeration caking when breaing up not thorough and dry and burning, it can improve waste incineration efficient effectively, reduces and burns cost.
