Description
Technical field
The utility model relates to a kind of bypass type flue gas waste heat recovery systems, are applied to bypass type flue gas waste heat recovery work
Skill is suitble to the waste heat of gas-fired water heating boiler, gas turbine, coal-burning boiler or similar industry to recycle.
Background technique
Bypass type flue gas waste heat recovery technique, is mainly characterized by waste heat utilization equipment and is mounted on gas bypass, by drawing
Boiler exhaust gas (or other heat source exhausts) are introduced bypass and are recycled by blower, then pass through original chimney or newly-built chimney
It is discharged into atmosphere.In this recovery process, waste heat utilization equipment and boiler can be one-to-one or one-to-many manner, take setting for smoke point
Setting the control with air-introduced machine is the key that waste heat reclaiming process, be easy to cause flue gas to overflow and dissipates or cold air flows backward problem, more than reduction
Recuperation of heat amount is especially apparent when taking smoke point setting bad, will such as take smoke point downstream upward as far as possible, then be easily reduced original system
Flue negative pressure has an impact to original system technique.When waste heat utilization equipment and waste heat source are in a pair of of multi-mode, flue gas pipeline is mutual
Even, the smoke blowing problem to put into operation between outaged equipment may cause the failure of project.
Utility model content
Purpose of the utility model is to overcome the above-mentioned shortcomings and provide a kind of bypass type flue gas waste heat recovery system and its
Cigarette control method is taken, bypass type flue gas waste heat recovery system can be optimized and take cigarette control problem, the excessive scattered or cold air of flue gas is solved and falls
Smoke blowing and balancing the load problem under filling problem, and a pair of of multi-mode, optimization system control, improve waste heat recovery volume.
Purpose of the utility model is realized as follows:
A kind of bypass type flue gas waste heat recovery system, including flue gas branch pipe, flue gas branch pipe one end is by taking cigarette threeway
Boiler back end ductwork final heat exchanger downstream flue is accessed, the other end is incorporated to flue gas main pipe, and the boiler back end ductwork final stage is changed
Hot device smoke inlet is equipped with precondition pressure sensor, and described take is equipped with temperature sensor, sets on the flue gas branch pipe at cigarette threeway
Have a chimney valve, the flue gas main pipe entrance is equipped with main-piping pressure sensor, the main-piping pressure sensor and flue gas heat-exchange unit it
Between be equipped with air-introduced machine.
Preferably, the flue gas branch pipe is multiple, and multiple flue gas branch pipes are incorporated to flue gas main pipe.
The beneficial effects of the utility model are:
The utility model wide adaptability, it is insensitive to original system and operation control method, it runs smoothly low in energy consumption, flue gas overflows
The rate of dissipating is low, 95% or more flue gas of recoverable waste heat source；
The operation halted state that can accurately and timely monitor boiler, opens and closes corresponding chimney valve, prevents from being pumped into cold air；Automatically
The aperture of chimney valve is adjusted, original system flue pressure is controlled；Smoke blowing is avoided, and reduces flue gas and overflows and dissipate, prevents cold air from tail portion
Flue flows backward.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Wherein: flue gas main pipe 1；Flue gas branch pipe 2；Chimney valve 3；Flue gas heat-exchange unit 4；Air-introduced machine 5；Precondition pressure sensor 6；
Main-piping pressure sensor 7；Temperature sensor 8.
Specific embodiment
Referring to Fig. 1, the utility model relates to a kind of bypass type flue gas waste heat recovery system, including flue gas branch pipe 2, the cigarettes
For 2 one end of gas branch pipe by taking cigarette threeway to access boiler back end ductwork final heat exchanger downstream flue, the other end is incorporated to flue gas main pipe
1, the boiler back end ductwork final heat exchanger smoke inlet is equipped with precondition pressure sensor 6, and described take is equipped with temperature at cigarette threeway
Sensor 8 is spent, the flue gas branch pipe 2 is equipped with chimney valve 3, and 1 entrance of flue gas main pipe is equipped with main-piping pressure sensor 7, institute
It states and is equipped with air-introduced machine 5 between main-piping pressure sensor 7 and flue gas heat-exchange unit 4.
The flue gas branch pipe 2 be it is multiple, multiple flue gas branch pipes 2 are incorporated to flue gas main pipe 1.
The utility model takes cigarette control method, comprising the following steps: flue gas branch pipe 2 is linked into boiler back end ductwork final stage
Heat exchanger downstream flue, precondition pressure sensor 6 is installed in boiler back end ductwork final heat exchanger smoke inlet side, in flue gas main pipe
2 installation main-piping pressure sensors 7, are taking mounting temperature sensor 8 at cigarette；It is sensed according to precondition pressure sensor 6, main-piping pressure
The data that device 7, temperature sensor 8 are fed back, control the aperture of chimney valve 3 and the operating load of air-introduced machine 5 after operation；Each waste heat source
The flue gas of generation converges to flue gas main pipe 1 by flue gas branch pipe 2, is discharged after the recycling of flue gas heat-exchange unit 4.
In addition to the implementation, the utility model further includes having other embodiments, all to use equivalents or equivalent
The technical solution that alternative is formed, should all fall within the protection scope of the utility model claims.
