Abstract
The considerations of for miniature boiler manufacturing cost and operating cost, overwhelming majority small-sized biomass boiler, biomass boiler containing household small-size are without special dust-extraction unit at present, or the discharge of dust is only reduced using simple increase flue length and backhaul number, cannot fundamentally meet the needs of people are to environment higher standard, or even the discharge standard of country and place is not achieved in biomass boiler also；The present invention relates to a kind of miniature stalk boiler dust collect unit by water, due to use water in dust removal in real time and online with boiler slag removal uniform stirring, go out combustion, cooling and humidification processing are carried out to high-temperature ash, directly squeezed by spiral tapping machine again into the grey bag of dedicated collection, solves the maximum problem of water process of cleaning, that is the handling problems of water in dust removal not only play the role of preventing ashes from flying upward with the wind, but also produce active influence to return field, transport and the circulation of lime-ash.
Description
Technical field:
The present invention relates to boiler dusting technical fields more particularly to a kind of miniature stalk boiler dust collect unit by water and water in dust removal to dispose
Method.
Background technique:
In China, straw biomass enormous amount based on agricultural waste material generates nearly 900,000,000 tons every year, and these are given birth to
Substance is widely distributed, is a kind of very clean renewable energy, so biomass fuel and biomass boiler technology have obtained
To more and more attention and exploitation, at present mainly using biological substance shaped granule fuel and biomass granule fuel pot
Furnace；Although biomass fuel is generated in burning, exhaust emission is minimum, and the organic matter of unique unfortunately fuel is burned
Cheng Zhonghui generates a large amount of dust emissions among atmosphere, adverse effect is generated to air quality, particularly with miniature stalk pot
For furnace, the considerations of for manufacturing cost and operating cost, most small-sized biomass boilers are filled without special dedusting
It sets or the discharge of dust is only reduced using the simple length for increasing flue and backhaul number, but cannot fundamentally meet
Demand of the people to environment higher standard；It is learnt from the dust-cleaning scheme of current existing miniature boiler, water dedusting is that solution is small-sized
A kind of higher method of straw boiler dedusting Energy Efficiency Ratio, but the disadvantage of dust collect unit by water maximum is exactly to ask the disposition of water in dust removal
Topic.
Therefore, it is necessary to provide a kind of miniature stalk boiler water dust catcher device and water in dust removal method of disposal is above-mentioned to solve
Technical problem.
Summary of the invention
In order to solve the above problem, the present invention provides a kind of new miniature stalk boiler dust collect unit by water and water in dust removal disposition
Method.
