Abstract
The utility model discloses a boiler furnace negative pressure control system, including furnace, its cigarette end of furnace is connected to the chimney bottom through dust remover and first draught fan, the heat exchanger is installed to the chimney top, the heat exchanger is connected to furnace through the phase -change thermal ware and advances the mouth, phase -change thermal ware and furnace advance to install the second draught fan between the mouth, install pressure monitoring equipment in the furnace, pressure monitoring equipment, first draught fan and second draught fan are connected to the switch board respectively. The utility model discloses a boiler furnace negative pressure control system monitors furnace's pressure through pressure monitoring equipment, through the intake with go out air regulation, realize furnace temperature regulation, the air inlet is hot -blast through after the heat transfer, can not cause very big fluctuation to furnace, simultaneously, under the certain condition of air inlet, lacks coal alarm device and reports to the police, suggestion coal, its safety simple to use.
Description
Technical field
This utility model relates to a kind of boiler components, is specifically related to a kind of boiler furnace vacuum control system, belongs to boiler technology field。
Background technology
Boiler is a kind of energy conversion, and the energy to boiler input has the chemical energy in fuel, electric energy, and boiler output has the steam of certain heat energy, high-temperature water or organic heat carrier；The hot water produced in boiler or steam directly can provide required heat energy for commercial production and people's lives, it is possible to be converted to mechanical energy by Steam Power Equipment, or convert mechanical energy into electric energy again through electromotor；The boiler providing hot water is called hot-water boiler, is mainly used in life, also has a small amount of application in commercial production；The boiler producing steam is called steam boiler, is often simply called boiler, is used for thermal power station, boats and ships, locomotive and industrial and mining establishment；In boiler combustion process, if combustion chamber draft is too little, even for just, then in burner hearth, flue gas is too much, and even flue gas outwards emits, and affects the safety of equipment and operator；Otherwise, combustion chamber draft is too small, and cold air can be made to leak in burner hearth, from but thermal loss increase, reduce efficiency of combustion；It is therefore desirable to be able to burner hearth is carried out Stress control。
Utility model content
(1) to solve the technical problem that
For solving the problems referred to above, the utility model proposes a kind of boiler furnace vacuum control system, by pressure monitoring devices, the pressure of burner hearth is monitored；And regulate in real time。
(2) technical scheme
Boiler furnace vacuum control system of the present utility model, including burner hearth；The smoke end of described burner hearth is connected to chimney bottom by cleaner unit and the first air-introduced machine；Described chimney top is provided with heat exchanger；Described heat exchanger is connected to burner hearth smoke inlet by phase change heat accumulator；Second air-introduced machine is installed between described phase change heat accumulator and burner hearth smoke inlet；In described burner hearth, pressure monitoring devices is installed；Described pressure monitoring devices, the first air-introduced machine and the second air-introduced machine are connected respectively to switch board。
As preferred embodiment, between described burner hearth its smoke end and cleaner unit, the second heat exchanger is installed；Described second heat exchanger outfan is connected to phase change heat accumulator。
As preferred embodiment, its smoke end of described burner hearth is provided with gaseous mass detection probe。
As preferred embodiment, described switch board place is provided with scarce coal alarm device。
(3) beneficial effect
This utility model compared with prior art, boiler furnace vacuum control system of the present utility model, by pressure monitoring devices, the pressure of burner hearth is monitored；Adjustment by intake and air output, it is achieved fire box temperature regulates, air intake be by heat exchange after hot blast, burner hearth will not be caused very big fluctuation, meanwhile, when under air intake one stable condition, lack coal alarm device and report to the police, point out coal, its use is simple and safe。
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model。
Detailed description of the invention
Boiler furnace vacuum control system as shown in Figure 1, including burner hearth 1；Burner hearth 1 smoke end is connected to bottom chimney 4 by cleaner unit 2 and the first air-introduced machine 3；Chimney 4 top is provided with heat exchanger 5；Heat exchanger 5 is connected to burner hearth 1 smoke inlet by phase change heat accumulator 6；Second air-introduced machine 7 is installed between phase change heat accumulator 6 and burner hearth 1 smoke inlet；Pressure monitoring devices 8 is installed in burner hearth 1；Pressure monitoring devices the 8, first air-introduced machine 3 and the second air-introduced machine 7 are connected respectively to switch board (not shown)。
Between burner hearth 1 its smoke end and cleaner unit 2, second heat exchanger 9 is installed；Second heat exchanger 9 outfan is connected to phase change heat accumulator 6。
Burner hearth 1 smoke end is provided with gaseous mass detection probe (not shown)。
Switch board place is provided with scarce coal alarm device。
Boiler furnace vacuum control system of the present utility model, is monitored the pressure of burner hearth by pressure monitoring devices；The major variable affecting furnace pressure has coal-supplying amount, to air quantity and convulsion amount etc., and wherein coal-supplying amount is determined by factors such as vapor (steam) temperature, pressure and evaporation capacity, so wanting to keep furnace pressure to remain unchanged within the specific limits can change convulsion amount and to air quantity, meanwhile, easily have influence on coal-supplying amount to air quantity, when to wind to predetermined value, lack coal alarm device to report to the police, reminding coal in burner hearth, air intake is hot blast, and it ensure that temperature in burner hearth。
