Life.
Nothing of the present invention alters the multiple thermal storage units and high-temperature flue gas concetrated pipe 1, heat of wind regenerative air preheater
Air pipe collector 9, cold flue gas concetrated pipe 11, cold wind concetrated pipe 17, driving motor 16 etc. are all disposed within inside steel structure frame 2,
And on the ground by the support of steel structure frame 2.Every nothing alters wind regenerative air preheater according to load difference, is arranged 2
Or 2 or more thermal storage units, each thermal storage unit 7,2 nothings containing 2 regenerative chambers alter wind type four-way valve, 4 connections, 90 ° of curved cigarettes
Pipe, 1 set of fire-proof motor, speed reducer and the chain transminssion mechanism of matching 4.
High-temperature flue gas concetrated pipe 1, hot-air concetrated pipe 9, cold flue gas concetrated pipe 11 and cold wind concetrated pipe 17 respectively with heating
The corresponding pipeline connection of furnace residual neat recovering system.
Without altering wind type four-way valve, there is the double-deck valve plate, have the characteristics that not alter wind, air leak rate of air curtain inside valve low.The valve plate valve
Core has 8 exemplary operation positions, wherein 0 ° (360 °), 90 °, 180 ° 270 ° is rest position；45°,135°,225°,315°
For peak load fully open position.Therefore, reasonable control valve Board position can be such that some regenerative heat exchange unit of preheater is stopped
Various states, the preheater load adjustable extents such as heat exchange, Smaller load throttling heat exchange, rated load heat exchange are big.The position of spool,
It can be combined with each other using travel switch and control program and realize control.
The commutation minor cycle of multiple thermal storage units is staggered the regular hour, adjusts in addition to four-way valve valve core rotation speed
Section, can be such that commutation process becomes flat, the pressure oscillation in cigarette air duct is minimum, and temperature fluctuation is smaller, and preheater pressure drop is steady
It is fixed, it realizes the safe and stable operation of reheat furnace system, guarantees that combustion system operates normally.
The valve core rotation speed of four-way valve is slower, and pressure oscillation is smaller；When multiple groups four-way valve commutates, mutual start-stop time
Difference is smaller, and registration is higher, and pressure oscillation is with regard to smaller.It is continuous always low when multiple groups four-way valve spool position holding certain angle
Speed rotates, and is minimum in system pressure wave theory, can almost ignore.
In order to make the pressure oscillation in cigarette air duct is small, range of temperature is small, preheater pressure drop loss maintain substantially constant,
Every nothing alters the thermal storage unit that two or more are arranged in wind regenerative air preheater, and by the Xiao Zhou of each thermal storage unit
Phase integrally combines arrangement, that is, controls the four-way valve switching time interval of each thermal storage unit and rationally adjust four-way valve valve core rotation
Commutating period can make flue gas in cigarette air duct, the pressure of air, temperature, pressure drop etc. keep substantially constant, be conducive to heating furnace and fire
The safe and stable operation of burning system.
When without altering the work of wind regenerative air preheater, 2 four-way valve cores of single thermal storage unit keep low speed synchronous
Rotation, carries out air, the runner of flue gas is slowly switched, and the four-way valve core of multiple thermal storage units is staggered certain angle, protects
Card is without wind regenerative air preheater Continuous Heat Transfer is altered, and pressure oscillation is minimum or small without fluctuation, temperature fluctuation in cigarette air duct, and nothing is altered
Wind regenerative air preheater pressure drop is stablized.
When nothing of the present invention alters wind regenerative air preheater applied to waste heat recovery system of petrochemical heating furnace,
The hot fume that the heating flue of residual neat recovering system comes enters high-temperature flue gas concetrated pipe 1, and is diverted to the high temperature of each thermal storage unit
Side four-way valve 3 imports corresponding regenerative chamber 7 by high temperature side four-way valve 3, and hot fume from top to bottom passes through accumulation of heat in regenerative chamber 7
Body 8 is heated to heat storage 8；Cold flue gas after heat exchange is imported into cold flue gas set by corresponding low temperature side four-way valve 14
Pipe 11, then residual neat recovering system cold smoke road is imported, chimney is discharged by air-introduced machine.It is sent at the same time by residual neat recovering system air blower
The cold air come is split into cold wind concetrated pipe 17 to the low temperature side four-way valve 14 of each thermal storage unit, by low temperature side four-way
Valve 14 imports in the corresponding regenerative chamber 7 in the other side, and cold air from bottom to top passes through heat storage 8 in regenerative chamber 7, absorbs and takes away
The heat of heat storage 8, the hot-air after heat exchange are imported into hot-air concetrated pipe 9, subsequently into remaining by high temperature side four-way valve 3
The main hot-flow flue of heat recovery system, send to Bottom of Heating Furnace, uses for burning.Heat storage accumulation of heat, heat release need the regular hour,
The minor cycle of i.e. single thermal storage unit after completing a minor cycle, drives accumulation of heat list by driving motor 16 and chain transminssion mechanism 4
Two four-way valves in member commutate simultaneously, switch the flow direction of flue gas and air, exchange the runner of flue gas and air, are blown
Cold regenerative chamber 7 is passed through high-temperature flue gas, cold air is then passed through by the regenerative chamber 7 of accumulation of heat, hence into the next of thermal storage unit
Minor cycle is recycled with this, continuous work heat exchange, so that Mist heat recovering is realized, the purpose that combustion air is preheated.
In conclusion being carried out using Mist heat recovering to combustion air by means of above-mentioned technical proposal of the invention
