Abstract
The utility model discloses a membrane method oxygen-enrichment combustion-supporting energy saving system, comprising an air blower (1), an air preheater (2) connected with the air blower (1), and a suction fan (3), the front end of the suction fan (3) is connected with an air filter (4), the back end of the suction fan (3) is connected with the inlet of a membrane method oxygen-enrichment generator (5), the outlet of the membrane method oxygen-enrichment generator (5) is connected with the inlet of a gas storage surge tank (8) successively via a water ring vacuum pump (6) and a gas water separation tank (7), and the outlet of the gas storage surge tank (8) is connected with the inlet of the air blower (1). The membrane method oxygen-enrichment combustion-supporting energy saving system is advantaged by simple structure, easy operation, low cost, concentration of oxygen of the combustion-supporting gas reaching 28%-32%, use in match with devices such as a kiln, a boiler, a gas generator, a fertilizer gas-making furnace, etc., and capability of effectively improving fuel combustion rate, and energy-saving rate reaching 5-20%.
Description
Technical field
The utility model relates to a kind of energy saver; Especially a kind of simple in structure, processing ease, with low cost can use, effectively improve the film oxygen enriching combustion-supporting and energy-saving system of fuel firing rate with matched with devices such as kiln, boiler, gas producer, chemical fertilizer gas-making stove.
Background technology
At present; Be applied to steam power plant, oil field and commercial production with boiler, gas producer, cement kiln and chemical fertilizer gas-making stove etc.; Basically all use air blast, air preheater in the combustion chamber, to spray into air, to improve the combustion rate of fuel by airborne oxygen through preheating.But because airborne oxygen content only accounts for about 21%, therefore existing burner all exists the inadequate problem of burning.Insufficient thermal conversion efficiency that not only influences fuel burns; Waste a large amount of coals, oil, natural gas equal energy source; But also can produce waste gas such as great amount of carbon dioxide, carbon monoxide, will cause environmental pollution like direct discharging, and the increasing expense is paid in discharging after treatment.
Summary of the invention
The utility model is in order to solve the above-mentioned technical problem of existing in prior technology; A kind of simple in structure, processing ease, with low cost is provided, can uses, effectively improve the film oxygen enriching combustion-supporting and energy-saving system of fuel firing rate with matched with devices such as kiln, boiler, gas producer, chemical fertilizer gas-making stoves.
The technical solution of the utility model is: a kind of film oxygen enriching combustion-supporting and energy-saving system; The air preheater that air blast is arranged and join with air blast; Be provided with induced-draught fan, at the front end of induced-draught fan air cleaner arranged, the inlet of the rear end of induced-draught fan and membrane type oxygen-enriched generator joins; The outlet of membrane type oxygen-enriched generator is joined through the inlet of water ring vacuum pump, gas water separation tank and gas storage vacuum tank successively, and the outlet of gas storage vacuum tank and the inlet of air blast join.
The utility model is simple in structure, processing ease, with low cost; Can make the oxygen concentration in the combustion-supporting gas reach 28% ~ 32%; Use with matched with devices such as kiln, boiler, gas producer, chemical fertilizer gas-making stoves, can effectively improve fuel firing rate, the energy conservation rate reaches 5 ~ 20%.Simultaneously can reduce toxic emissions such as carbon dioxide, carbon monoxide, be beneficial to environmental protection, can reduce the expense that takes place because of waste gas pollution control and treatment.
Description of drawings
Fig. 1 is the scheme of installation of the utility model embodiment.
The specific embodiment
Below with the specific embodiment of accompanying drawings the utility model.As shown in Figure 1: the same with prior art; The air preheater 2 that air blast 1 is arranged and join with air blast 1; Air preheater 2 outlets are joined with burner 9 (steam power plant, oil field and commercial production are with boiler, gas producer, cement kiln and chemical fertilizer gas-making stove etc.); Different is to be provided with induced-draught fan 3 with prior art, at the front end of induced-draught fan 3 air cleaner 4 is arranged, and the inlet of the rear end of induced-draught fan 3 and membrane type oxygen-enriched generator 5 joins; The outlet of membrane type oxygen-enriched generator 5 is joined with the inlet of gas storage vacuum tank 8 through water ring vacuum pump 6, gas water separation tank 7 successively, and the inlet of the outlet of gas storage vacuum tank 8 and air blast 1 joins.
The course of work:
Temperature sensor, B/P EGR Back Pressure Transducer EGR, flue gas sensor, steam pressure sensor and air concentration sensor etc. can be set on burner 9; Signal and automatic control cabinet that each sensor is exported join; The control of automatic control cabinet output frequency variation signal air blast 1, induced-draught fan 3 and water ring vacuum pump 6 etc. make burner 9 be in best work (burning) state all the time.
Claims (1)
