Description
Technical field
This utility model one improved boiler induced draught system, belongs to boiler draft technical field.
Background technology
Boiler operatiopn is independent operating, two boilers are with two negative-pressure air fans, when negative-pressure air fan quits work suddenly, boiler internal negative pressure disappears, and fuel gas buring is insufficient, produce mixed gas, easily there is explosion accident, when a Fans is faulty, without standby fan, one boiler operatiopn cannot meet Production requirement, does not reaches technological requirement temperature.
Utility model content
This utility model overcomes the deficiency that prior art exists, it is provided that a kind of improved boiler induced draught system that can increase boiler safety performance.
In order to solve above-mentioned technical problem, the technical solution adopted in the utility model is: a kind of improved boiler induced draught system, including two boilers and the first negative-pressure air fan, it is respectively provided with burner in two described boilers, the air inlet of described burner connects with extraneous gas pipeline, and can control to work according to the controller of self, described first negative-pressure air fan is arranged on the outside of boiler, the air of burning needs is provided for boiler, a first normally closed solenoid electric valve is electrically connected on described first blast blower fan, described first normally closed solenoid electric valve is electrically connected with central controller by circuit, described central controller is electrically connected with the controller of burner by circuit, for controlling the work of burner, alarm also it is electrically connected with on described central controller.
Preferably, said system also includes the second negative-pressure air fan and the second normally closed solenoid electric valve, described second negative-pressure air fan provides the air of burning needs for boiler, described second negative-pressure air fan and the first negative-pressure air fan are arranged in parallel in circuit, are electrically connected by the second normally closed solenoid electric valve between described second negative-pressure air fan and central controller.
This utility model compared with prior art has the beneficial effect that this utility model is compared with traditional induced draught system, two boiler for producing are driven by a Fans negative pressure, energy-saving and cost-reducing, negative-pressure air fan can series, parallel induced draught system, link burner alarm device, it is ensured that boiler works continuously, and add boiler safety performance accordingly, in the case of not newly added equipment, having stand-by equipment, having during repair and maintenance can stand-by equipment.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings this utility model is described further.
Fig. 1 is structural representation of the present utility model.
In figure: 1 be boiler, 2 be the first negative-pressure air fan, 3 be burner, 4 be the first normally closed solenoid electric valve, 5 be central controller, 6 be alarm, 7 be the second negative-pressure air fan, 8 be the second normally closed solenoid electric valve.
Detailed description of the invention
As shown in Figure 1, this utility model one improved boiler induced draught system, including two boilers 1 and the first negative-pressure air fan 2, it is respectively provided with burner 3 in two described boilers 1, the air inlet of described burner 3 connects with extraneous gas pipeline, and can control to work according to the controller of self, described first negative-pressure air fan 2 is arranged on the outside of boiler 1, the air of burning needs is provided for boiler 1, a first normally closed solenoid electric valve 4 is electrically connected on described first blast blower fan 2, described first normally closed solenoid electric valve 4 is electrically connected with central controller 5 by circuit, described central controller 5 is electrically connected with the controller of burner 3 by circuit, for controlling the work of burner 3, alarm 6 also it is electrically connected with on described central controller 5.
Including the second negative-pressure air fan 7 and the second normally closed solenoid electric valve 8, described second negative-pressure air fan 7 provides the air of burning needs for boiler 1, described second negative-pressure air fan 7 is arranged in parallel in circuit with the first negative-pressure air fan 2, is electrically connected by the second normally closed solenoid electric valve 8 between described second negative-pressure air fan 7 and central controller 5.
In the boiler negative pressure running of two, this utility model workshop, connect two boilers with a negative-pressure air fan, meet two safe operation of the boiler, and interlock burner warning system, when negative-pressure air fan quits work suddenly, burner source of the gas, boiler quits work.
Traditional boiler is in succession respectively two boilers with two blower fans, this utility model is then that a negative-pressure air fan is ined succession two boilers 1, burner 3 it is provided with on boiler 1, this utility model is on startup, first negative-pressure air fan 2 is energized, first normally closed solenoid electric valve 4, after central controller 5 obtains the instruction that the first negative-pressure air fan 2 normally works, controls burner 3 and starts working.
This utility model in system operation, the shutdown situation that negative-pressure air fan is likely to occur, the risk of initiation and make following improvement:
If 1 first negative-pressure air fan 2 self runs into fault or artificial false touch shutdown; first normally closed solenoid electric valve 4 disconnects, and after central controller 5 obtains the first out-of-work instruction of negative-pressure air fan 2 simultaneously, controls burner 3 and quits work; preventing boiler 1 from exploding, alarm 6 sends alarm simultaneously.First
2, there is the situation that boiler 1 is shut down in above-mentioned improvement; can work continuously in order to ensure boiler 1; using the other Fans in conventional boiler as standby fan; i.e. second negative-pressure air fan 7; once negative-pressure air fan 2 is shut down, and central controller 5 automatically controls the second negative-pressure air fan 7 energising and is operated, after the second normally closed solenoid electric valve 8 must electrically connect; triggering central controller 5 controls the burner 3 of boiler 1 and is operated, it is ensured that boiler 1 can work continuously.
Above in conjunction with accompanying drawing, embodiment of the present utility model is explained in detail, but this utility model is not limited to above-described embodiment, in the ken that those of ordinary skill in the art are possessed, it is also possible on the premise of without departing from this utility model objective, various changes can be made.
