Description

3D multi-level air intake burner assembly

Technical field

The utility model relates to a kind of 3D multi-level air intake burner assembly.

Background technology

In known technical field, the combustion gas that current China uses mainly contains liquefied gas, natural gas and artificial coal gas, and its Main Ingredients and Appearance is hydrocarbon, and the heating under anaerobic environment of this hydrocarbon can separate out free carbon, accumulates in and forms " carbon black " together.And the gas furnace of China's use on the other hand, great majority are atmospheric burning type mode, need the combustion-supporting ability normal combustion of air when combustion gas sprays from burner.But during a branch of combustion gas ejection, first can only meet with air at skin, after ignition device, carry out violent redox reaction (namely burning).The heat energy of its burning makes the inner part of failing to contact with air of combustion gas bundle reach the high temperature of more than 800 degree Celsius, thus makes combustion gas constantly separate out free carbon, accumulates in the bottom of a pan and forms our daily " pot is black " seen.It is worthy of note, except this visible " pot is black " is to except cooker, environment, the invisible harm of this kind of unburnt product to human body fails really to obtain the great attention of people always.Therefore the height of the efficiency of combustion of burner is very important.

Utility model content

The technical problems to be solved in the utility model is: overcome the problems referred to above, provides the 3D multi-level air intake burner assembly that a kind of sufficient combustion is even, efficiency is high.

The utility model solves the technical scheme that its technical problem adopts: a kind of 3D multi-level air intake burner assembly, comprise external burner and the built-in combustion device of central axes, described external burner has outer back-up ring, the inner ring position of described outer back-up ring vertical above be provided with inner shield ring, the burning circle of the stepped arrangement in some roads is provided with in turn by lower edge to the lower edge of inner shield ring of described outer back-up ring, centered by the central axis of described inner shield ring, every circle of burning together is evenly provided with the longitudinal burner port of a circle, described built-in combustion utensil has the cyclic ligand fluid being positioned at outer back-up ring bottom section, annular flow chamber is offered downwards at the upper surface of described cyclic ligand fluid, the outer wall of described annular flow chamber is evenly provided with lateral-combustion hole.

Further, be conducive to being evenly distributed of combustion flame as a kind of concrete version, the distribution in diagonal upward direction from outside to inside of the circle of burning described in the utility model.

Further, as a kind of concrete version, upper end open, the lower end of annular flow chamber described in the utility model are airtight, and are provided with through hole at the center of described cyclic ligand fluid.

Further, more evenly reliable in order to make burned flame distribute, in the utility model, the inside and outside wall of every circle of burning is together equipped with tapering, and described burning circle is in up-small and down-big shape.

Further, as a kind of concrete version, the upper end end face of outer back-up ring described in the utility model is lower than the upper end end face of inner shield ring.

Further, as a kind of concrete embodiment, the circle that burns described in the utility model has three roads at least.

The beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, by stepped structure and inside and outside split-type design, the effect of burning can be made more abundant, the distribution of its combustion flame simultaneously presents stepped, not only form the burning of at least three layers, be conducive to the abundant mixing of oxygen, sufficient combustion and evenly, the thermal efficiency is high, stratified combustion is tapered, every grate firing burns high-visible and has third dimension, simultaneously according to the effect of the alteration of form combustion efficiency of burning vessel, simultaneously can according to the bottom shape self adaptation of the burned utensil of reality, fabulous adjustment capability can be possessed, has practical value.
