Technical field
The utility model relates to the equipment that a kind of calcium sulfate is produced sulfuric acid, especially relates to the heat circulating equipment that a kind of calcium sulfate is produced sulfuric acid.
Background technology
In China, the production of sulfuric acid comprises acid production with sulphur, pyrite-based sulfuric acid production, metallurgical off-gas acid-making, these acid preparing methods, the overwhelming majority all adopts more advanced double-absorption technology, wherein the heat that produces in the chemical reaction process is appreciable, and fully recycling these heats is vital tasks of sulfuric acid manufacturing.
In the double-absorption acid-making process, usually 800-1000 in the calcination process ℃ waste heat is called high-temperature residual heat, account for 60% of waste heat total amount, warm waste heat during waste heat in the conversion process about 500 ℃ is called, account for 15% of waste heat total amount, about 100 ℃ waste heat is called low temperature exhaust heat in the dried suction process, accounts for 25% of waste heat total amount, and high-temperature residual heat and middle temperature waste heat are because the temperature height, recycle than being easier to, the low temperature exhaust heat temperature is low, and the acid temperature is relevant with the concentration of acid, in pyrite-based sulfuric acid production, one concentration of inhaling acid and two suction acid are 98%, the acid temperature is about 100 ℃, and the concentration of dry acid is 93%, and sour temperature is about 70 ℃; In acid production with sulphur technology, a concentration of inhaling acid, two suction acid, dry acid is 98%, and sour temperature is about 100 ℃.Because recovery difficult is big, therefore most of gas washing in SA production producer does not reclaim low temperature exhaust heat, the acid that has low temperature exhaust heat that generally will the generate acid cooler of flowing through, carry out the heat exchange cooling with circulating water, doing not only like this, low temperature exhaust heat is not used, and in order to reduce the temperature of acid, also need to use a large amount of cooling waters, not only waste energy but also waste the water source.
Chinese invention patent application 200510022528.X discloses the new method that used heat utilizes in the fluidized bed furnace in a kind of sulphuric acid process, the flue gas that will come out in the fluidized bed furnace is used for adding hot water or air is realized respectively providing hot water and heating installation to the user, but this application is subjected to region and environmental limit, and Application feasibility is also little.
China's utility model patent 200820019657.2 discloses a kind of closed device that utilizes residual heat of sulfuric acid production to heat, it comes the water in the heating pipe to give user's heat supply with acid cooler as medium, but the user must be separated by nearerly with equipment, otherwise application performance is bad.
The utility model content
The technical problems to be solved in the utility model is, overcomes the deficiencies in the prior art, provides a kind of calcium sulfate that can recovery waste heat to produce the heat circulating equipment of sulfuric acid, the conversion of its energy, easy to use.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of calcium sulfate is produced the heat circulating equipment of sulfuric acid, comprises heat exchanger, steam turbine, generator, condenser and water pump; Described heat exchanger is located at the outside wall surface of producing the calcining kiln that sulfuric acid uses, and heat exchanger is connected with steam turbine by pipeline; Steam turbine links to each other with condenser by pipeline, and steam turbine directly is connected by flange with generator, and condenser links to each other with heat exchanger by the pipeline that has water pump.
The course of work: calcining produces high temperature in the calcining kiln, high temperature is delivered to the heat exchanger of calcining kiln outside wall surface, water flowing circulates in the heat exchanger, water at high temperature level pressure (level pressure mainly is in order to keep the stable flow rate of water circulation, the stability that keeps mass exchange, the size of pressure is relevant with the size of equipment and specification) being heated is converted into superheated vapour, superheated vapour is delivered to steam turbine by pipeline, and in steam turbine isothermal expansion, further pushing turbine running, steam turbine directly is connected with generator, with the high pressure (size of pressure size and calcining kiln, the heat release scale is relevant, pressure is mainly derived from the water expanded by heating, relevant with heat exchange, and the heat of calcining kiln is delivered in and might changes in the course of reaction, and the heat transmission after the heat transmission when just dropping into material is finished with end reaction is differentiated) momentum transfer of superheated vapour is to generator, is converted into electric energy by generator; Superheated vapour is converted into moist steam after by steam turbine, and moist steam is converted into condensate water in condenser compression set temperature cooling decided at the higher level but not officially announced; Condensate water is decided the entropy compression by water pump and is entered the heat exchanger circulation.
Use the equipment of the utility model, take full advantage of the waste heat in the calcium sulfate production sulfuric acid process, transfer and transforming principle by heat, waste heat is converted into the kinetic energy pushing generator generating of water vapour, realized effectively recycling to heat, overcome heat application and thermal source apart from the property problem, electric energy can store or deliver to electrical network, it is also convenient to use.
