Utility model content
The purpose of this utility model is to provide dust concentration supervising device in a kind of ash-transmission system, and this device can realize the concentration of the dust in on-line real time monitoring ash-transmission system, improves the stability in power plant's ash-transmission system.
To achieve these goals, the utility model provides dust concentration supervising device in a kind of ash-transmission system, in this ash-transmission system, dust concentration supervising device comprises: dust concentration detector, is arranged in ash-transmission system, for detecting the dust concentration value in ash-transmission system; Warning device and/or blow device; And control device, receive described dust concentration value, and when described dust concentration value is greater than preset value, perform following at least one: control described warning device and report to the police; And control described blow device the dust in ash-transmission system is purged.
Preferably, in described ash-transmission system, dust concentration supervising device also comprises: valve switch, and this valve switch is arranged on the unimpeded passage place of ash-transmission system, and when described dust concentration value is greater than described preset value, described control device controls described valve switch and opens.
Preferably, described dust concentration detector is arranged on the gas exhaust duct of described ash-transmission system storehouse pump.
Preferably, described valve switch is dome valve.
Preferably, described warning device is audible-visual annunciator.
By technique scheme, use dust concentration detector to monitor in real time ash-transmission system, and be greater than preset value alarm in dust concentration value, facilitate staff to process in time, the adjustment for ash-transmission system provides and reliably operates easily.In addition, also can realize by blow device the automatic process that stifled grey defect occurs ash-transmission system, effectively reduce the workload of staff.
Other features and advantages of the utility model are described in detail in embodiment part subsequently.
Accompanying drawing explanation
Accompanying drawing is used to provide further understanding of the present utility model, and forms a part for instructions, is used from explanation the utility model, but does not form restriction of the present utility model with embodiment one below.In the accompanying drawings:
Fig. 1 shows the supervising device structured flowchart of dust concentration in the ash-transmission system that the utility model provides.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.Should be understood that, embodiment described herein, only for instruction and explanation of the utility model, is not limited to the utility model.
Fig. 1 shows the supervising device structured flowchart of dust concentration in the ash-transmission system that the utility model provides.As shown in Figure 1, in ash-transmission system, the supervising device of dust concentration can comprise: dust concentration detector 10, is arranged in ash-transmission system, for detecting the dust concentration value in ash-transmission system; Warning device 30 and/or blow device 40; And control device 20, receive described dust concentration value, and when described dust concentration value is greater than preset value, perform following at least one: control described warning device 30 and report to the police; And the dust controlled in described blow device 40 pairs of ash-transmission systems purges.By using dust concentration detector to monitor in real time ash-transmission system, and be greater than preset value alarm in dust concentration value, facilitate staff to process in time, the adjustment for ash-transmission system provides and reliably operates easily.
Dust concentration detector 10 can be arranged on the gas exhaust duct of ash-transmission system storehouse pump, carries out in real time or regular monitoring the dust of ash-transmission system.Control device 20 can be included in the control system of ash-transmission system, but is not limited to this.
In addition, blow device 40 can be set to control device 20 and control blow device 40 and automatically purge the dust in ash-transmission system, or can be set to, after warning device 30 is reported to the police, manually open blow device and purge, but be not limited to this.
In addition, warning device 30 can be audible-visual annunciator, the monitoring image of control system sends sound, light is reported to the police, but be not limited to this.
Dust concentration detector 10 is being arranged on after in ash-transmission system, is needing to debug it, using dust concentration detector 10 to collect the dust concentration of storehouse pump discharge under the various loading condiction of unit, and comparing to verify dust concentration detector with result on the spot.
In control device 20, the preset value of dust concentration can be determined in the following manner: use the correlative value that the dust concentration detector 10 debug is determined with dust concentration in ash-transmission system under failure condition in normal comfortable situation, and the dust concentration value under failure condition is set to threshold value, when dust concentration value is greater than threshold value, control device can control described warning device 30 and report to the police, warning device 30 can send sound on the monitoring image of control system, light is reported to the police, and reminds staff's ash-transmission system dust concentration too high; And the dust controlled in described blow device 40 pairs of ash-transmission systems purges simultaneously, can realize by blow device 40 the automatic process that stifled grey defect occurs ash-transmission system, effectively reduce the workload of staff.
In addition, the dust concentration supervising device that the utility model provides can also comprise valve switch, this valve switch is arranged on the unimpeded passage place of ash-transmission system, and when described dust concentration value is greater than described preset value, described control device 20 controls described valve switch and opens.Increase this valve switch, when ash-transmission system breaks down or occur stifled ash, control device 20 controls this valve switch and opens, and dust purging to unimpeded passage can be beneficial to dust and discharge by blow device 40.
Valve switch can be dome valve, is controlled lead-in wire and causes control device 20, controlled by control device to it during use.But the kind of family of power and influence's switch is not limited to this.
In addition, valve switch also can be set to manual unlocking, is opened it, but be not limited to this after warning device 30 is reported to the police by staff.
