Description
Technical field
The utility model relates to a kind of combustion-supporting oxygenerator of using of rotary kiln for kilns such as cement rotary kiln, non-ferrous metal metallurgy rotary kilns.
Background technology
When the rotary kiln work such as cement rotary kiln, non-ferrous metal metallurgy rotary kiln, need to come combustion-supporting with a large amount of oxygen, generally adopt at present burner blower to come combustion-supporting to rotary kiln air blast, but its combustion-supporting effect does not reach optimum regime, cause fuel consumption many, waste gas is many, efficiency is low, and not energy-conserving and environment-protective, according to experiment, oxygen content be controlled at 26%～30% between time, combustion efficacy is best, energy-conserving and environment-protective, but atmospheric oxygen content is nowhere near, and therefore need to design a set of oxygen and mixed oxygen device comes to rotary kiln combustion-supporting.
Utility model content
The utility model technical issues that need to address are to provide a kind of combustion-supporting oxygenerator of using of rotary kiln to kiln oxygen, mixing use.
For addressing the above problem, technical solution adopted in the utility model is: a kind of rotary kiln is combustion-supporting with oxygenerator, it is characterized in that: comprise air cleaning unit and oxygenerator, wherein refining plant comprises air compressor machine, cooling driers, activated carbon tower, air cushioning tank and air vessel, air compressor machine outlet connects the import of air cushioning tank, the outlet of air cushioning tank connects cooling driers import, and cooling driers outlet connects activated carbon tower import, and activated carbon tower outlet connects oxygenerator through air vessel; Oxygenerator comprises pressure-variable adsorption device, oxygen surge tank, oxygen canister, and the import of pressure-variable adsorption device connects the outlet of air vessel in air cleaning unit, and the outlet of pressure-variable adsorption device connects oxygen surge tank, and the outlet of oxygen surge tank connects oxygen canister.

Described pressure-variable adsorption device is two covers, and every cover comprises two adsorption towers, and one for absorption, one for desorbing, and two covers are in parallel to be used.
The beneficial effect that adopts technique scheme to produce is: it is combustion-supporting that the utility model is applied to rotary kiln, increased the oxygen content of unit air, improved the temperature of flame in rotary kiln, reduce the consumption of fuel, use before fuel consumption reduced 15%, improve efficiency simultaneously and reached the object of environmental protection and energy saving, product quality has promoted a step, has improved product production.
Accompanying drawing explanation
Fig. 1 is the utility model equipment layout and schema;
Wherein: 1, air compressor machine, 2, air cushioning tank, 3, cooling driers, 4, activated carbon tower, 5, air vessel, 6, adsorption tower, 7, oxygen surge tank, 8, oxygen canister, 9, mixing tank, 10, gas blower, 11, rotary kiln.
Embodiment
Below in conjunction with accompanying drawing, utility model is described in further detail: as shown in Figure 1, this novel air cleaning unit and oxygenerator of comprising, wherein refining plant comprises air compressor machine 1, cooling driers 3, activated carbon tower 4, air cushioning tank 2 and air vessel 5, air compressor machine 1 outlet connects 2 imports of air cushioning tank, 2 outlets of air cushioning tank connect cooling driers 3 imports, cooling driers 3 outlets connect activated carbon tower 4 imports, and activated carbon tower 4 outlets connect oxygenerator through air vessel 5; Oxygenerator comprises pressure-variable adsorption device, oxygen surge tank 7, oxygen canister 8, and the import of pressure-variable adsorption device connects the outlet of air vessel 5 in air cleaning unit, and the outlet of pressure-variable adsorption device connects oxygen surge tank 7, and 7 outlets of oxygen surge tank connect oxygen canister 8.The sorbent material using in described pressure-variable adsorption device is molecular sieve, and pressure-variable adsorption device is two covers, and every cover comprises 6, one of two adsorption towers for absorption, and one for desorbing, and two covers are in parallel to be used.The oxygen that oxygenerator grows is delivered to rotary kiln 11 through pipeline combustion-supporting after being transported to air that mixing tank 9 sends here with gas blower 10 and being mixed by pipeline.The oxygen content of the gas mixing in mixing tank 9 is controlled between 26%～30%.
Principle of work:
Air is the pressurized air after air compressor machine 1, air cushioning tank 2, cooling driers 3, activated carbon tower 4, air vessel 5 purifying treatment (dehumidifying, oil removing, dedusting) successively, enter pressure-variable adsorption device, under the effect of pressure-variable adsorption, make nitrogen oxygen separated, thereby effectively enrichment oxygen.The sorbent material using is a kind of molecular sieve, and due to kinetic effect, the rate of diffusion of oxygen on molecular sieve be apparently higher than nitrogen, and when absorption reaches balance far away, oxygen is got up by enrichment effectively in gas phase.This device adopts two adsorption towers to form a pressure swing adsorption system, utilizes this system just can complete sorbent material Adsorption and desorption process, and sorbent material Adsorption and desorption process cycle alternation between two adsorption towers, to realize the high-quality oxygen of continuous production.It is standby that the oxygen of producing through oxygenerator (adsorption tower) enters oxygen canister after the surge tank buffering of kicking up, and the oxygen of oxygen canister is sent into mixing tank and air mixed, and oxygen content is controlled between 26%～30%, then it is combustion-supporting to send into rotary kiln.
This novel combustion-supporting principle analysis:
Use oxygen enrichment, Pure Oxygen Combustion Technology can make nitrogen amount reduce, air capacity and exhaust gas volumn all significantly reduce, therefore flame temperature significantly improves along with the increase of oxygen proportion in combustion air, but oxygen concn is unsuitable too high, research both domestic and external all shows: the volume fraction of oxygen is best when 26%～30% left and right, and oxygen concn every lifting one percentage point flame temperature between 26%～30% improves 35 ℃.When the volume fraction of oxygen is in 28% left and right in the gas that oxygenation combustion-supporting apparatus produces, can be effectively improve 50 ℃ of left and right by furnace temperature is whole, oxygen level is to be increased to 30% increasing degree of flame temperature when above less.
