Abstract
The invention relates to a multi-stage rotating energy-saving dust and harmful substance removing vertical boiler which belongs to the technical field of boilers. 10 layers of horn-type holes with various angles are arranged in a hearth, air entering in the hearth forms rotating air to promote micro coal dust, tar and flame to be mixed and promote soft coal to be fully combusted in the hearth, andheat energy in the soft coal can be fully released, therefore the heat energy utilization ratio in the soft coal is improved; the remaining time of the heat energy is stopped in the hearth, therefore, the heat efficiency of the boiler is improved; the dust is blocked to discharge outside so as to promote the dust to fall in the hearth, black smoke and the dust are eliminated to pollute outside environment, and the dust is eliminated by adopting a water spraying method so as to achieve the purpose of saving water.
Description
Technical field:
The invention belongs to the boiler technology field
Background technology:
I investigate to the north 12 provinces and cities myself, and boiler unit, the secondary blast system that establishes are made and used in all parts of the country in the circle boiler furnace, its structure ubiquity is unreasonable, produce the composition that to burn in the coal, can not all burn, to external world's discharging black smoke and flue dust.Waste energy on the one hand, on the other hand contaminated environment.Also adopt the water spray to eliminate flue dust, the waste great lot of water resources.Adopt big capacity blower and air-introduced machine, waste a large amount of electric energy.
The application's Patent data source: I produce and use the field investigation of boiler unit to 12 provinces and cities in the north by secondary, and the data on the various boiler books also selects for use Liaoning Province electrical power industry bureau group to compile the boiler operatiopn book.39 pages of figure of in April, 06 second edition, 41 pages of B and C figure are for referencial use.I combine through prolonged and repeated research and test myself., produce large-tonnage product, the supply the market practical application according to this structural principle.Every energy-saving index and environmental protection index all surpass state-set standard.
Summary of the invention:
To fall the defective that above-mentioned unreasonable structure produces in order overcoming, to improve unreasonable structure.If multistage (ten kinds of angles) rotary nozzle is replaced unreasonable structure secondary rotation air port.All nozzle angle is all towards a direction, with multistage rotation wind, be ejected into flame top in the burner hearth, the air that enters in the burner hearth forms power in burner hearth, impel the composition that can burn in air, flame and the coal, mixed combustion fully discharges the heat energy that contains in the coal fully, improves heat energy utilization rate in the coal.Block heat energy time of staying in burner hearth, improve boiler thermal output.Also block dust not to external world's discharging, impel dust to fall in the burner hearth, eliminate black smoke and contamination by dust external environment.Also eliminate and adopt the water spray to fall dust, reach using water wisely.Adopt low capacity air blast and air-introduced machine, reach the purpose of saves energy.Make economic benefit and social benefit all reach beneficial effect.
