Description
Technical field: the lime shaft kiln unit that the present invention relates to various manufacturing lime.
Background technology: the fuel that the existing limestone kiln unit of producing lime uses is coal, and in process of production, coal is block the mixing with Wingdale to be present in an independently space, because the burning of a carbon atom; Need the oxygen molecule could perfect combustion, and that coal cinder quality have be several, the carbon of tens even dozens of molar mass, supposes that a coal cinder has n mole carbon, so; A coal cinder perfect combustion needs the individual oxygen molecule in n * 6.023 * 10 (23 power), even polyoxy molecule more, yet in the ignition dope air that uses, only contains 21% oxygen; In the space of high temperature closure, the coal cinder major part is surrounded by Wingdale, limited can with space that air contacts in because high temperature; In the air oxygen still less, coal cinder is surrounded by nitrogen in most of the time, most of space, in the working process of limestone kiln, burning of coal needs a large amount of oxygen; And combustion reactions in finite time, the finite space, coal is excessive, the oxygen wretched insufficiency; The result causes coal combustion insufficient, and airborne nitrogen and oxygen at high temperature react, and produces oxynitride; Poor efficiency, pollution, energy resource waste, cost is high, problems such as deficiency in economic performance.
Summary of the invention: main purpose of the present invention be exactly solve to make lime the limestone kiln unit in the course of the work; The oxygen wretched insufficiency, it is combustion-supporting to change into excessive pure liquid oxygen to the past air-breathing, makes oxygen not enough; Coal is excessive, and to become oxygen excessive; In incendiary moment, sufficient oxygen is arranged, make the instantaneous effective rate of combustion of coal reach the upper limit (UL) value; Gaseous media reduces 79% in the combustion reactions, and the heat that tail gas is taken away reduces 79%; Do not have nitrogen in the combustion reactions, just do not have oxynitride to produce.Advantage of the present invention: energy-conservation 80%, reduce discharging 95%.The scheme of specifically dealing with problems: remove the combustion air plenum system that lime is made unit; Make the lime of unit and connecting tube composition high-efficient energy-saving environment friendly through liquid oxygen jar, interchanger, well heater, pressure surge tank, oxygen flow modulator, lime and make unit; Make unit ignition dope gas inlet pipe to oxygen outlet pipe and lime and be connected, directly supply with lime to excessive purity oxygen and make the unit combustion chamber; The water coolant of making lime unit feeds interchanger as heating medium, with the oxygen generation heat exchange from the liquid oxygen jar, reclaims heat energy, improves evaporation efficiency; The tail gas of making lime unit feeds well heater as heating medium, improves oxygen temperature, reclaims heat energy once more, improves the heat energy utilization rate, reduces cost.A kind of lime of high-efficient energy-saving environment friendly is made unit by liquid oxygen jar 1, interchanger 2, well heater 3; Pressure surge tank 4, oxygen flow modulator 5, lime are made unit 6 and are formed with connecting tube; Wherein 7 is that lime is made unit ignition dope air and oxygen flow modulator oxygen outlet pipe connecting; The 8th, pressure surge tank oxygen outlet and oxygen flow modulator oxygen inlet pipe connecting, the 9th, lime is made the outlet of unit tail gas and heater heats gas feed pipe connecting, the 10th, well heater oxygen outlet and pressure surge tank oxygen inlet pipe connecting; The 11st, through the tail gas outlet blow-down pipe of well heater; The 12nd, lime is made unit cooling water outlet and interchanger heating carrier inlet connecting branch, and the 13rd, the outlet of interchanger heating carrier is made unit entrance of cooling water pipe connecting, the 14th, interchanger oxygen outlet and well heater oxygen inlet pipe connecting with lime; The 15th, liquid oxygen jar oxygen outlet and interchanger oxygen inlet pipe connecting, its system guarantees excessive purity oxygen and coal generation combustion reactions.
Description of drawings: Fig. 1 is a primary structure synoptic diagram of the present invention, and description of reference numerals is following: the 1st, and liquid oxygen jar, the 2nd, interchanger; The 3rd, well heater, the 4th, pressure surge tank, the 5th, oxygen flow modulator; The 6th, lime is made unit; The 7th, lime is made unit ignition dope air and oxygen flow modulator oxygen outlet pipe connecting, and the 8th, pressure surge tank oxygen outlet and oxygen flow modulator oxygen inlet pipe connecting, the 9th, lime is made outlet of unit tail gas and heater heats gas feed pipe connecting; The 10th, well heater oxygen outlet and pressure surge tank oxygen inlet pipe connecting; The 11st, through the tail gas outlet blow-down pipe of well heater, the 12nd, lime is made unit cooling water outlet and interchanger heating carrier inlet connecting branch, and the 13rd, the outlet of interchanger heating carrier is made unit entrance of cooling water pipe connecting with lime; The 14th, interchanger oxygen outlet and well heater oxygen inlet pipe connecting, the 15th, liquid oxygen jar oxygen outlet and interchanger oxygen inlet pipe connecting.
