Description
Technical field
The invention belongs to a kind of technical field of exhaust heat recovery equipment, and in particular to a kind of based on more than the heat accumulating type for automatically controlling
Heat recovery equipment and processing method, it is adaptable to industrial furnace flue gas waste heat recovery, are especially adapted for use in heat-accumulating type high-temperature fume afterheat
The industrial furnace flue gas waste heat recovery field of intelligent automatic control in removal process, it is also possible to as industrial furnace flue gas exhaust heat intelligence
Change reclaimer to use.
Background technology
In flue gas waste heat recovery field, develop into earthenware from ND steel to resist dew point corrosion, flue gas waste heat recovery
Most effective, most economical rational method is technology utilization, and it be very that after technology utilization, the waste heat recovery of low temperature position flue gas is
Careful, because combustion process can produce sour gas, waste heat recovery is excessive will to occur dew point corrosion, and dew point corrosion is electricity
Chemical attack, corrosion rate are fast, consequence it is serious for can both make equipment failure in one week of carbon steel, for rustless steel 40
Corrosion failure is will also result within it, the normal operation of device is had a strong impact on, if containing sulfur in fuel, can make flue gas dew point
Temperature is lifted, and as the heat exchange area of existing flue gas waste heat recovery apparatus is fixed, has 30% in the design of device produce load
Operating flexibility, the temperature change in elastic range, it should be flue gas dew point temperature and the temperature variation in the range of operating flexibility
Sum, and practical situation to be the user having only pursue energy-saving effect, blindly increase heat exchange area, and the purpose of waste heat recovery is to reach
Arrive, but device loses operating flexibility, hidden danger is brought to the safety of device production, also to the scale benefit safety of device
Bring hidden danger.The structure of wall-type heat exchange have board-like, cast panel formula (cast panel formula can be divided into two kinds of cast iron and cast steel again), heat pipe-type,
Phase transformation boiler etc., it is current to have developed ceramic composite pipe again, thermal resistance value is increased again to dividing wall type heat transfer, will reach same effect
Will increase input, and decline economic rationality, metal waste heat recovery apparatus will have the use bottleneck of inborn dew point corrosion；Store
Hot type waste heat recovery is the flue gas waste heat recovery form of new development, such as a kind of entitled heat accumulation type trans-critical flue gas waste-heat recoverer
And the Chinese patent of Patent No. CN200910028334.9, discharge below the flue gas dew point of trans-critical flue gas waste heat, flue gas dew
The following discharge position of point is difficult to determine that the protection below dew point will also increase investment, decline economic rationality, especially to user
The psychological shade for bringing dew point corrosion to occur, has a kind of operation psychological security hidden danger；Such as Patent No. CN201120245296 and
A kind of Chinese patent of entitled heat accumulating type waste heat recovery system, the reciprocal switching of its two sets of waste-heat recovery devices just produce moment
Connectivity problem, causes the potential safety hazard ganged up；And Patent No. CN201210449433.6 and a kind of entitled heat accumulating type waste heat
The Chinese patent of unit equipment and its temperature-controlled process is reclaimed, is then realized by method that is multigroup in parallel and cutting off simultaneously joint group
Flue-gas temperature does not reach the control of dew point, and this requires to start to design group number to be designed enough, otherwise, is extremely difficult to reducing
Temperature controlled purpose, the method are not carried out automatically controlling, and regulation afterwards means potential safety hazard, and such multigroup
Connection is also uneconomical.
