Description

A kind of cold rolling processing line annealing furnace hydrogen recovery system
Technical field
The present invention relates to a kind of cold rolling processing line hydrogen recovery systems, and in particular to one kind being based on hydrogen fuel cell and waste heat The cold rolling processing line hydrogen recovery system of retracting device.
Background technology
In the technological process of production of the cold rolling continuous processing line of existing silicon steel, carbon steel and stainless steel, it will produce a large amount of Useless H2, air is directly discharged into because that can not utilize：
In the production technology of silicon steel decarburizing annealing processing line (DCL), to avoid belt steel surface from generating fayalite (Fe2SiO4), it is necessary to it is passed through a large amount of H2To ensure bringing-up section is certain in stove H2Partial pressure；And in carbon steel continuous annealing line, to make Strip reaches the very fast cooling rate of technological requirement, and rapid cooling section also needs to be passed through a large amount of H2；Meanwhile almost all of cold rolling Continuous Heat In each section of burner hearth for handling line, it is required for being passed through a large amount of H2As protection gas, to maintain Deoxidation Atmosphere in Furnace.

On the other hand, the technological break-through that hydrogen fuel cell constantly obtains in recent years, with H2For fuel, with O2It is anti-through electrochemistry It should be produced electricl energy afterwards through film.Hydrogen fuel cell is a kind of power generator of electrochemistry, and reaction process is not related to burning, but Directly chemical energy is converted to electric energy without through overheated machine process, not limited by Carnot cycle, thus energy conversion efficiency is very It is high.Meanwhile hydrogen fuel cell reliable operation, quiet, reaction production object only have H2O neither will produce CO2Isothermal chamber gas, also not It will produce nitrogen oxides pollution.As a kind of efficient, environmental protection, clean new energy, hydrogen fuel cell can become the changes such as coal, oil The alternative energy source of stone fuel has huge development potentiality.
Hydrogen fuel cell technology type is more, and solid oxide fuel cell (SOFC) is one such, work temperature Up to 600~1000 DEG C of degree, and efficiency is higher, the useless H with silicon steel decarburizing annealing heat-treatment lines (DCL) discharge2Temperature is the most Agree with.The reaction principle figure of solid-oxide fuel cell (SOFC) is shown in that attached drawing 2, reactive chemistry formula are as follows：
Anode：
Cathode：
It is whole：
How the chemistry of cold rolling processing line annealing furnace hydrogen is efficiently recycled using hydrogen fuel cell and heat recovery technology Energy and thermal energy are to avoid the important topic that energy waste and environmental pollution are that the present invention studies.
Therefore, it is necessary to a kind of new structures to solve above-mentioned problem.

The principle of the present invention is to pass through the useless H that cold rolling processing line annealing furnace during traditional handicraft is discharged2, according to it Source inputs two subsystems respectively：Main discharge recovery and processing system 400 and time discharge recovery and processing system 500.First pass through height Warm heat exchanger reduces temperature, then generates electricity through hydrogen fuel cell device, and by combustion chamber and waste-heat recovery device, at recycling The useless H of lineation annealing furnace discharge2Contained in energy, a part be recycled to processing line H2Public auxiliary system circulation utilizes.
For practical operation, as shown in Figure 3 due to the useless H of cold rolling processing line2Mainly via main floss hole, on a small quantity via Two kinds of channel discharges of secondary floss hole between each section, for different discharge capacity sheets, the H of processing line annealing furnace discharge2It is divided into two Road respectively enters main discharge recovery and processing system 400 and time discharge recovery and processing system 500, is recycled according to different flows：
As shown in Fig. 2, when processing line annealing furnace 100 is in steady operational status, through H2Main floss hole 310 is discharged largely Useless H2Processing system 400, H is received into main drain back into2Through the first high-temperature heat-exchanging 410 700 DEG C are cooled to from 900 DEG C.H2Into The main purpose of one high-temperature heat-exchanging 410 heat exchange is the SOFC hydrogen of mainstream at present in order to protect the first hydrogen fuel cell device 420 The electrolyte of fuel cell mainly uses Y2O3Stable ZrO2, excessively high temperature can reduce its durability.Heat exchanger recycles Heat, can be used for handle line itself each heating system.
H2Into the anode of the first hydrogen fuel cell device 420；First pressure indicates controller 471 according to the stove detected Voltage-controlled first pressure regulating valve 472 processed, when furnace pressure is too low or excessively high, first pressure indicates controller 471 controllable first Pressure-regulating valve 472 adjusts H2Flow, to ensure that the furnace pressure of processing line annealing furnace is stablized within the scope of technological requirement.
First flow control valve 453 is according to H2The first orifice flowmeter 451 and first flow in gas circuit indicate controller 452 H2Flow signal controls air mass flow；Work as H2When changes in flow rate, air mass flow is controlled, to ensure to enter the first hydrogen fuel The H of cell apparatus 4202With O2Ratio is in zone of reasonableness.
Air enters the cathode of the first hydrogen fuel cell device 420 through the first compressor 460；H2With the O in air2In hydrogen Electrochemical reaction occurs in fuel cell and generates direct current, the direct current of generation switchs to alternating current through the first inverter 430 and is followed by Enter power grid；
A surplus air part after being reacted by the first hydrogen fuel cell device 420 is again through the first compressor 460 It is passed through the first hydrogen fuel cell device 420；The surplus air that general hydrogen fuel cell device has about 20% does not participate in reaction, Cycle is passed through air and the ratio that hot-air participates in reaction can be improved, and improves energy recovery efficiency.
Remaining H after being reacted by the first hydrogen fuel cell device 4202Residue is recycled through the first cryogenic heat exchanger 440 After heat, after first filter 481, main discharge recovery and processing system air exhauster 482 and cooling heat exchanger 483, it is cooled to 20 DEG C, the H of processing line can be passed directly into2Public affairs additionally arrange standby recycle；Work as H2When temperature reduces, inside the H that contains2O steam meetings It is condensed into liquid H2O, the H after gas-liquid separation2In can only contain N2, and it is N to handle protection gas in the stove of linear system system2H2Mixing Gas takes back to public auxiliary system according to its ratio, N can be improved2H2The utilization rate of gaseous mixture, further decreases enterprise energy consumption.
On the other hand, when processing line annealing furnace 100 is in steady operational status, the H of 100 each sections of processing line annealing furnace2 The useless H of the discharge of secondary floss hole 3202Into secondary discharge recovery and processing system 500.And secondary discharge recovery and processing system 500 is in the second hydrogen Structure and main discharge recovery and processing system 400 before fuel-cell device 520 is essentially identical.
The difference is that due to the H of each section floss hole2Discharge capacity is relatively small, in H2With the O in air2Through fuel After battery is electrochemically reacted, secondary discharge recovery and processing system 500 is provided with combustion chamber 580, remaining unreacted H2Through Second cryogenic heat exchanger 540 recycles heat, is directly entered combustion chamber 580 with surplus air and burns, the heat of generation, through remaining Heat recovery system 590 is recycled, and can be used for handling the heating device of line many places.
The specific implementation mode of the present invention is illustrated above, but the present invention is not limited thereto, without departing from Spirit of the invention, the present invention can also have various change.
