Abstract
A method for reclaiming the afterheat (at 350 deg.C) of the tail gas generated by preparing sodium hexametaphosphate features that an afterheat steam drum composed of buffer tank, heat exchanger and heat conductive tube is installed onto tail gas pipeline to heat the water (at 20 deg.C) and generate steam for reusing it.
Description
Technical field
The present invention relates to the method that a kind of using waste heat from tail gas is recycled, particularly a kind of method of producing the using waste heat from tail gas recycling of sodium hexametaphosphate generation.
Background technology
The exhaust emissions amount of producing 40000 tons of calgon process units per year is 100,000 Nm
3/ h, the exhaust emissions temperature is higher, reaches more than 350 ℃, and the discharging of a large amount of high-temperature tail gas is corroded for the tail gas conveying equipment greatly, and has been caused serious pollution to regional environment, wastes a large amount of heat energy.
Summary of the invention
Purpose of the present invention just provides a kind of method of producing the using waste heat from tail gas recycling of sodium hexametaphosphate generation, and it is absorbed into water vapour by the waste heat drum with using waste heat from tail gas, utilizes for producing again.
The object of the present invention is achieved like this: a kind of method of producing the using waste heat from tail gas recycling of sodium hexametaphosphate generation, the waste heat drum is installed on the exhaust pipe that sodium hexametaphosphate is produced, the waste heat drum is made up of surge tank, heat exchanger and heat pipe, with the temperature that produces in producing is that 350 ℃ tail gas conducts heat in the heat exchanger by the heat pipe in the heat exchanger in the waste heat drum, with temperature is that 20 ℃ water heating produces water vapour, the steam that produces is through steam-flow meter, enter the steam pipe system of plant area, use as heated air.
The present invention has reduced the temperature of exhaust emissions by a large amount of high-temperature tail gas waste heat recoveries to the production process generation, the steam that the alternative boiler of a large amount of steam of generation produces; saved fire coal; protected environment, really realized cleaner production having realized recycling economy development.
Description of drawings
Concrete structure of the present invention is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is technological process of production figure of the present invention.
Fig. 1 double as Figure of abstract.
The specific embodiment
As shown in Figure 1, a kind of method of producing the using waste heat from tail gas recycling of sodium hexametaphosphate generation, the waste heat drum is installed on the exhaust pipe that sodium hexametaphosphate is produced, the waste heat drum is made up of surge tank, heat exchanger and heat pipe, with the temperature that produces in producing is that 350 ℃ tail gas conducts heat in the heat exchanger by the heat pipe in the heat exchanger in the waste heat drum, with temperature is that 20 ℃ water heating produces water vapour, the steam that produces is through steam-flow meter, enter the steam pipe system of plant area, use as heated air.
From melting the high-temperature gas that comes out in the poly-stove under the effect of air-introduced machine, enter the tail gas flue, enter surge tank then, the flue gas that comes out from surge tank enters heat exchanger, contact with heat pipe, the heat of high-temperature gas passes to hydraulic fluid in the heat pipe by heat pipe low side tube wall, gasification after hydraulic fluid is heated, gas after the gasification rises and arrives the heat pipe top, by heat pipe upper end tube wall with the water in the heat transferred heat exchanger, temperature in the heat exchanger be 20 ℃ of water under high temperature action, gasification becomes the saturated vapor about 150 ℃ rapidly, and pressure reaches 7 atmospheric pressure, the steam that produces enters the steam pipe system of plant area through steam-flow meter, as the heated air of full factory.
Claims (1)
1, a kind of method of producing the using waste heat from tail gas recycling of sodium hexametaphosphate generation, it is characterized in that: the waste heat drum is installed on the exhaust pipe that sodium hexametaphosphate is produced, the waste heat drum is made up of surge tank, heat exchanger and heat pipe, with the temperature that produces in producing is that 350 ℃ tail gas conducts heat in the heat exchanger by the heat pipe in the heat exchanger in the waste heat drum, with temperature is that 20 ℃ water heating produces water vapour, the steam that produces is through steam-flow meter, enter the steam pipe system of plant area, use as heated air.
