Description
Technical field
The injection that the present invention relates to a kind of incinerator mixes burning device, relates in particular to a kind of injection with pyrolysis gas injection and fully oxidation and mixes burning device.
Background technology
The burning disposal of clinical waste is many at present carries out in incinerator, and incinerator generally comprises a combustion chamber and a dual firing chamber, and a combustion chamber is used for the pyrolysis or the burning of clinical waste, and dual firing chamber is used for the high-temperature oxydation of flue gas.For guaranteeing the abundant oxidation of flue gas, generally in dual firing chamber's configuration booster burners.Since require flue gas time of staying of high temperature section more than 850 ℃ greater than 2s, then there is certain space requirement in dual firing chamber, and the abundant oxidation of harmful substance in excessive lifting that is unfavorable for temperature in space and the flue gas, the factory that has adds one in a combustion chamber with dual firing chamber and mixes and fire the contradiction that space requirement and temperature rise are solved in the chamber on communicating pipe.Mix the combustion chamber generally by one section or two sections revolving body chambers (specifically be shaped as: interlude is that cylinder, two ends are Rotary-table) formation, adopt the mixed combustion chamber of two sections revolving body chamber structures generally to replenish preheated air, guarantee oxygen-enriched atmosphere in the chamber second section chamber porch.The incinerator that the waste disposal amount is little mixes the combustion chamber and is generally one-part form.Flue gas enters mixed fire chamber through pipeline perpendicular to mixing combustion chamber axis direction by a combustion chamber, and booster burners is arranged in mixes combustion chamber axis direction, mixes and fires the chamber axis other end towards dual firing chamber, promptly holds towards dual firing chamber thus through the flue gas of high-temperature oxydation.Mix the heat that the combustion chamber can concentrate booster burners to produce, the harmful substance in the abundant oxidation flue gas, the use that can save combustion-supporting fuel guarantees to burn effect and saved operating cost.
For the harmful smoke that produces in guarantee burning does not leak, incinerator generally adopts the method for operation of little negative pressure, and negative pressure is produced by the air-introduced machine that is installed in before the aiutage.In small-sized medical wastes incineration stove, because exhaust gas volumn is little, the use of air-introduced machine increases equipment cost and operating cost.
The use that incinerator mixes the combustion chamber makes moderate progress the present situation of small incinerator unit's waste disposal energy consumption height, flue gas poor processing effect, but has also increased running resistance greatly, increases the power of smoke evacuation air-introduced machine, promptly increases energy consumption.It is not obvious to the energy-saving effect that incinerator brings that incinerator mixes the utilization of firing the chamber, the inreal high difficult problem of small incinerator energy consumption that solves.
Summary of the invention
The injection that the objective of the invention is to design in order to solve problem such as above-mentioned technology a kind of incinerator mixes burning device.
(1) technical problem that will solve
Will the unit's of solution waste disposal energy consumption height in the design of the mixed combustion chamber of small incinerator, the flue gas running resistance is big, the high-power problem of smoke evacuation air-introduced machine.
(2) technical scheme
In order to solve the problems of the technologies described above, the present invention adopts a kind of injection with pyrolysis gas injection and fully oxidation to mix burning device, and is achieved through the following technical solutions:
It is in one in conjunction with injector and the dominance structure that mixes the combustion chamber that the injection of a kind of incinerator of the present invention mixes burning device, make full use of the flame dynamic pressure of booster burners, pyrolysis smoke in the injection one combustion chamber carries out abundant oxidation to mixing the combustion chamber, reaches the purpose of harmful components in the harmless treatment flue gas.Mainly constitute by burning jet pipe, air receiving chamber, the mixed combustion of injection chamber, secondary blowing system, diffusion reative cell.
Described injection mixes burning device and comprises a burning jet pipe and the mixed combustion of injection chamber body, adorn a burner in the burning jet pipe, the outlet of burning jet pipe is flame jet, the burning jet pipe is coaxial with the central axis that injection mixes combustion chamber body, and the distance that burning jet pipe and injection mix combustion I-I cross section, chamber remains between the 40mm-200mm adjustable; Injection mixes combustion chamber body and comprises flue gas receiving chamber, injection mixing chamber, secondary air distribution device, wind distributing hole and diffusion reative cell.Functions such as combustion air, fuel atomization, ignition are provided by burner, the high temperature gas flow that produces after in the burning jet pipe, utilizing burner combustion, because its speed raises, pressure reduces, the flue gas stream suction injection that one combustion chamber, front is entered in the receiving chamber enters mixing chamber, two fluid streams are mixed into one air-flow gradually in mixing chamber, mix by the secondary blowing system then and enter dual firing chamber after fresh air enters diffusion reative cell recovery pressure.
Use above-mentioned injection principle in the present invention, utilize burner ejection gas flow rate that flue gas is sucked.Since flue gas at high temperature with the hot-air generation chemical reaction of burner ejection, gas volume increases, and also follows volume to increase when two strands of gases mix, so different with common injector on the structure.
Compared with prior art, the invention has the beneficial effects as follows:
(1) the small-sized medical wastes incineration stove that the mixed burning device of this injection is housed is kept burning with the refuse self heat, and the air-introduced machine of need not discharging fume, and guarantees burning disposal effect and energy-conserving and environment-protective;
(2) solved unit waste disposal energy consumption height preferably, the flue gas running resistance is big, increases the high-power problem of smoke evacuation air-introduced machine.
(3) ejection system does not have moving component, simple in structure, reliable.
