Abstract

The invention relates to a vertical efficient and energy saving (dual purpose) boiler which is suitable for air feed for enterprise production and heating for office and residential buildings, and particularly relates to an efficient and energy saving boiler consisting of a boiler periphery waste heat absorbing system and an in-boiler heat absorbing high-temperature system. The water, oil and the other heat conduction mediums can be used. The return water of a central heating system firstly enters a boiler periphery waste heat absorbing large water jacket to absorb the waste heat to raise the temperature, then enters a water inlet at the bottom layer of one of multiple layers of heat absorbing ring-shaped water jackets and enters a circular water jacket to circulate for a cycle to exchange heat, enters a water inlet at the bottom layer of a second layer of the heat absorbing ring-shaped water jackets through connection tubes to exchange heat, and enters a high-temperature boiler container after the temperature is raised in a layer-upon-layer manner, and then, the water is output from an upper water outlet of the boiler to the central heating system. Two valves of the connection tubes are regulated when the boiler is started for use. One or more layers of heat absorbing ring-shaped water jackets are arranged upon a hearth and presented in flame, and the flame surrounds the ring-shaped water jackets, and goes externally and returns internally for multiple times to exchange heat; and in the ascending process, the external waste heat is absorbed by the large water jacket outside of the boiler, and a hand is not scaled when the waste heat reaches a chimney. Compared with the boiler sold in the market and currently used, 30% of coal can be saved by using the boiler, and the boiler is a good helper of a user for reducing operation investment.

Description

Vertical high-efficiency energy-saving (dual-purpose) stove

1, the technical field advantage is suitable for that residential quarter, enterprises and institutions are used, every stove can be for the heating heat of ten thousand square metres of 1-3,, be that factory and enterprise is produced air feed with think equipment at present, it has small investment, floor space advantage little, easy to install.

The experimental design of going through several years goes out this vertical heating stove, it has the advantages that heat exchange area is big, the thermal efficiency is high, heat exchange is economized on coal soon, safety coefficient is high.

2, technical background:

Before vertical boiler was born in 60 years in the early days of foundation, it was that some enterprises and institutions, plant produced development aspect play the effect that can not be substituted for many years.Because boiler internal structure majority is waterpipe type or fume tube type; Because heat exchange area is little; The scorching utilization rate of fire is low, can observe several meters high chimney sometimes unintentionally in the distance and burn with anger, according to the scorching utilization rate of measuring and calculating coal fire only about 70%; Owing to aspects such as one-time investment are few, remain the capital equipment of some enterprises and institutions so far.Now the whole nation is just at the vertical boiler of utilization and operation nearly millions of, if long-term the use gone down to coal in China being a tremendous loss waste.

3, the main contents of invention new technology:

In stove above the fiery chamber design and installation 1-multilayer ring-like water sleeve high temperature flue that absorbs heat, layering will intimately be measured to pass and given water, control the utilization rate of fire inflammation with the number of plies of water jacket.Received fabulous endothermic effect.In order to make full use of fiery scorching waste heat, designed peripheral round water jacket and absorbed fiery scorching waste heat.In design stove external and internal compositions, consider the natural movement law that hydro-thermal expands and rises, give the outer water jacket of the ring-like water sleeve stove of heat absorption in the stove, designed the same flow direction of current of low in and high out.Water water jacket inside and outside the stove gets into for low mouthful meets that heat rises, premium on currency Wen Yuegao more, and the high-temperature water of flue gets into heating installation.The backwater of heating installation is got back to inlet opening, peripheral water jacket bottom automatically, after absorbing fiery scorching waste heat and slowly rising to the apopore of stove outer end, gets into the flow process that the ring-like water jacket of heat absorption heats up once more in the stove again automatically.The scorching utilization rate of fire reaches 95% or more, the chimney breast non-scald on hand, the vertical boiler ratio that uses according to present market sale and unit, economizes on coal 30%, and hope can become national popularization substitute products.

4, manufacturing process and materials used:

Full stove can weld with steel plate, interior furnace structure, outer stove water jacket split welding back assembling, and interior stove absorbs heat ring-like water jacket can Foundry Production, can cast out heat absorbing sheet and come endothermic effect better, can reduce the number of plies of the ring-like water jacket of heat absorption like this.This production, manufacturing process is simple, easy for installation, cost is low, for the boiler for producing enterprise development provides rare opportunity.

Vertical two-purpose stove energy-conservation (dual-purpose) stove current trend and heat absorption temperature-rise period

Water is introduced water inlet 1 under the ring-like water jacket of heat absorption, is got into all heat exchange that circulate of the ring-like water jacket of heat absorption from outer furnace temperature water jacket top 6 outlet pipe; From water jacket outlet water from thereon mouth 2, getting into the second layer ring-like water jacket end opening that absorbs heat; Circulate a week again heat exchange heat up, water is suitable for reading from the second layer ring-like water jacket that absorbs heat, and is getting into the 3rd layer of ring-like water jacket end opening of heat absorption; Gain of heat circulation heats up again; Water, flows through all ring-like water jackets that absorb heat of top and heats up to the intensification heat exchange with same circular flow, gets into high temperature flue end opening 3, high temperature flue 4, input heating installation at last; From the heating installation return pipe get back to water jacket lower water inlet 5 outside the stove again, the water that gets into the outer water jacket of stove slowly rises, absorb fiery scorching waste heat and heat to stove warm water sleeve top pipe outlet 6, entering ring-like water jacket end opening 1 circulation of absorbing heat again of absorbing heat automatically.

The scorching heat exchange trend of fire

Stove fire chamber fire inflammation be distributed in fiery chamber top each layer heat absorption water jacket about; Fire is walked crosswise the outside of the ring-like water jacket of heat absorption, and the outer warm water sleeve inner panel of stove is toward up, walks to the retaining fire and puts to turn back behind the dirt plate and melt down the center; Again to being up to high temperature flue bottom; Walk crosswise the outer warm water sleeve inner panel of stove again outward, be up to the outer warm water sleeve top board of stove, the chimney breast non-scald on hand is emerged, reached to return the outlet to the stove central chimney.
