多驱动逆推式炉排焚烧垃圾的方法和设备

The character of the invention is that the composite reciprocating story fire grate is divided into one or two of drying areas, one or two combustion areas and one or two of ashes areas. Each hydraulic cylinder drives active fire grates in each area independently. It is needed to maintain a gap between active fire grate and fixed fire grate, and labyrinth typed structure is kept in their contact part. The driving shaft passes through the up side plate of the low air chamber. Rotary seal is utilized between each shaft and the up side plate. The multiple driving structures is good for controlling burning as well as meets the requirement of the ashes areas so as to lower the rate of heat slag and raise the performances of incinerators.

Two-step separation process for treating sewage

A two-step separation process for treating sewage features that an evaporation step is used to remove the liquid pollutants whose boiling point is higher than that of water and a self-evaporation or distillation step is used to remove the liquid pollutants whose boiling point is lower than that of water. It includes pre-treating, clarifying, pre-heating, evaporation, condensing, self-evaporation,distillation and draining or application. Its advantages are closed continuous operation, high speed and effect and low cost.

Household garbage incineration fume treatment reaction additive

The invention relates to a household garbage incineration fume treatment reaction additive which comprises kieselguhr, activated clay and active alumina, wherein the weight ratio of kieselguhr to activated clay to active alumina is (6-8):(1-3):(0.5-1.5); the fineness of the kieselguhr is greater than or equal to 250 meshes; the fineness of the activated clay is greater than or equal to 200 meshes; the fineness of the active alumin is greater than or equal to 325 meshes. The additive has the technical effects that the requirements on treatment on harmful heavy metal and organic compounds inside the garbage incineration fume are completely met, the additive is non-toxic and odorless, is light and convenient to package and transport, and is an ideal substitute of activated carbon, however, the price of the additive is only a fraction of that of the activated carbon, and moreover the functions of reducing the resistance and protecting a cloth bag dust collector are achieved.

House refuse treatment method for city

The municipal house refuse treatment method includes the following steps: zoning nunicipal refuse and stacking it in storage pool, stirring, natural fermentation for 4-6 days; spraying fermented diffusate into furnace to make high-temp. pyrolysis; and decomposing the harmful gas escaped by fermentation into odourless gas; incinerating the fermented refuse in refuse incinerator, separating solid furnace slag by magnetic method to remove iron, then sieving for application; and utilizing the high temp. flue gas produced by refuse incineration to heat the water being in the furnace to produce saturated steam or superheated steam which can be supplied for steam turbo-unit to generate power or heating for external system. Said invention does no pollute environment, can produce heat energy and possesses good treatment effect.
