Abstract
The utility model provides a hydrogen recycling and purifying device of a stainless steel band continuous bright heat treatment furnace. Waste gas discharged from a bright heat treatment furnace firstly enters a tube type water cooler through a hydrogen inlet of a recycling and purifying device and then enters a dedusting and deoiling device for removing dust and oil mist mixed with hydrogen, and impurities including oxygen and water in the hydrogen are removed through a catalysis deaerator and a regenerative adsorption dryer after the waste gas is supercharged by using a fan, and thus waste hydrogen is changed into high-purity hydrogen, and only a small amount of fresh high-purity hydrogen needs to be supplemented to return to the bright heat treatment furnace together with the obtained high-purity hydrogen. By using the hydrogen recycling and purifying device of the stainless steel band continuous bright heat treatment furnace, the energy consumption can be lowered obviously, the cost is reduced, and the bright annealing quality of the stainless steel band is improved.
Description
Technical field:
The present invention relates to hydrogen recovery purifying and recycling plant.The concrete stainless steel band plate bright heat treatment furnace that is used for.
Background technology:
Existing Stainless Steel Band continuous bright heat treatment furnace mostly adopts the high-purity hydrogen protection, to guarantee that annealing can completely cut off air fully under 1050 ℃ of left and right high temperature, realizes the Stainless Steel Band bright heat treatment.That its hydrogen purity requires is high, consumption large and hydrogen is all direct burning and exhausting in stove.Under the background of competition of market economy fierceness, in order to reduce production costs, the problem that hydrogen recovery purifying in the urgent need to address can recycle.
Summary of the invention:
The object of the present invention is to provide a kind of hydrogen recovery purification cycle using appts for Stainless Steel Band continuous bright heat treatment furnace.It is characterized in that waste gas is at first by the cooling of tubulation water cooler, then by dedusting oil eliminator oil removing dedusting, remove oxygen and moisture content in hydrogen through the adsorption dehumifier of two tower parallel connections of the catalytic deoxidation device of sending into the splendid attire palladium catalyst after the frequency conversion fan supercharging and splendid attire 5A molecular sieve again, hydrogen after purification returns to bright annealing oven, realizes recycling of hydrogen.
The useless hydrogen purity of being discharged by heat treatment furnace is higher, and is mingled with the impurity such as a large amount of dust and mist of oil.Therefore, then the dedusting oil removing of at first will lowering the temperature uses the blower fan supercharging, then removes oxygen and steam in dehydrogenation by hydrogen catalytic adsorption purifier apparatus.In hydrogen, oxygen can be down to 2ppm at this moment, and dew point can reach below-70 ℃.Hydrogen after purification can be sent into heat treatment furnace and recycle.Its process flow sheet is referring to accompanying drawing.
Technical characterstic:
1. the hydrogen purity that reclaims purification process is high, greatly is conducive to improve the quality of Stainless Steel Band clean annealing.
2. whole device operational safety, reliable, have oxygen sensor can monitoring hydrogen in oxygen level, having the PLC Controlling System can automatic alarm, chain and protection.
3. the employing frequency conversion fan, can adjust air quantity, blast, stable operation, energy efficient automatically.
4. hydrogen recovery rate of the present invention can reach more than 70%, only needs three months just costs of investment of energy retrieving arrangement, can greatly reduce the cost of stainless steel bright heat treatment.It has obvious society and economic benefit.
Description of drawings:
Figure of description is the process flow sheet of the hydrogen recovery purification cycle using appts of Stainless Steel Band continuous bright heat treatment furnace, and complete assembly comprises: 1. condenser, 2. dedusting oil eliminator, 3. freq uency conversion supercharging blower fan, 4. catalytic deoxidation device, 5-1/2. adsorption dehumifier.
Embodiment:
Certain Stainless Steel Band continuous bright annealing furnace.During normal operation, High Purity Hydrogen protection gas consumption 40Nm
3/ h, originally combustion gas is all by spark arrester emptying.After adopting hydrogen recovery purification cycle using appts of the present invention, the useless hydrogen of discharge high temperature is delivered to water cooler 1 by the DN50 weldless steel tube can make spent air temperture be down to below 50 ℃, can remove most dust and mist of oil in useless hydrogen through dedusting oil eliminator 2 again, then can make useless hydrogen be pressurized to 30kpa with booster fan 3, delivering to catalytic deoxidation device 4 can be down to oxygen level in useless hydrogen below 2ppm again, by the molecular sieve adsorption moisture eliminator, moisture is down to below 3ppm at last.Useless hydrogen can be changed into high-purity hydrogen, only needs this moment to replenish a small amount of fresh high-purity hydrogen, delivers to together bright annealing oven and recycles.
Hydrogen recovery purification cycle using appts main technical details of the present invention:
1. processing amounts of hydrogen: 20-1000Nm
3/ h
2. outlet hydrogen purity: oxygen level＜2ppm, dew point＜-70 ℃
3. the catalytic deoxidation furnaceman makes temperature: 80-100 ℃
4. the working temperature of adsorption dehumifier: normal temperature
5. the regeneration temperature of adsorption dehumifier: 200-300 ℃.
