Abstract
The utility model provides an oxygen -eliminating device water level monitoring device, including oxygen -eliminating device (1), oxygen -eliminating device water tank (2), the 1st water level monitoring ware (3), the 2nd water level monitoring ware (4), the 3rd water level monitoring ware (5), the below in oxygen -eliminating device (1) is installed in oxygen -eliminating device water tank (2), install in oxygen -eliminating device water tank (2) outlying one end the 1st water level monitoring ware (3) and the 2nd water level monitoring ware (4), install at oxygen -eliminating device water tank (2) the outlying other end the 3rd water level monitoring ware (5). The utility model provides a this kind of oxygen -eliminating device water level monitoring device, it is with low costs, but and the reliability of greatly increased oxygen -eliminating device water level signal, avoid the undulant equipment trouble who arouses of its mistake, improved the operational reliability of equipment, guarantee the unit safety steady operation.
Description
Technical field
The utility model relates to the oxygen-eliminating device technical field of improvement in power plant, particularly a kind of deaerator level supervising device.
Background technology
In the process that Power Plant puts into operation, the side of oxygen-eliminating device is provided with two differential pressure type deaerator level supervising devices, oxygen-eliminating device real time water level is delivered to distributed AC servo system cabinet (DCS) by these two water level monitor devices, carries out corresponding operating by DCS according to setting logic.But because opposite side does not install water level monitor device, cause opposite side water level effectively not monitor.Secondly, along with the prolongation of working time, electronic devices and components and signal transmission line will be aging gradually, when one of them water level monitor device of side break down fluctuate by mistake time, DCS will be caused to make false judgment, visual plant (electric pump) is likely caused to stop transport, or excision oxygen-eliminating device deaerating effect, have a strong impact on unit safety operation.
Utility model content
In order to solve the problem, the utility model proposes a kind of deaerator level supervising device, be arranged on deaerator storage tank (2), comprise n water monitor, n >=3; Wherein a part of water monitor is arranged on the peripheral one end of deaerator storage tank (2), a part is arranged on the peripheral other end of deaerator storage tank (2) in addition, and the water level signal that a described n water monitor records is sent to dcs.
Particularly, a described n water monitor is the first water monitor (3), the second water monitor (4) and the 3rd water monitor (5), described first water monitor (3) and the second water monitor (4) are arranged on the peripheral one end of deaerator storage tank (2), and described 3rd water monitor (5) is arranged on the peripheral other end of deaerator storage tank (2).
The water level signal that described first water monitor, the second water monitor and the 3rd water monitor record is sent to dcs, does 3 get 2 logical operations by dcs.
A kind of deaerator level supervising device that the utility model proposes, cost is low, and greatly can increase the reliability of deaerator level signal, avoids its equipment failure caused of by mistake fluctuating, improves the operational reliability of equipment, ensures unit safety stable operation.

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.
As shown in Figure 1, a kind of deaerator level supervising device, comprise oxygen-eliminating device, deaerator storage tank, the first water monitor, the second water monitor, the 3rd water monitor, described deaerator storage tank is arranged on the below of oxygen-eliminating device; Described first water monitor and the second water monitor are arranged on the right side of deaerator storage tank periphery, and described 3rd water monitor is arranged on the left side of deaerator storage tank periphery.Be arranged on the 3rd water level monitor device in left side, be in same level with two water level monitor devices on right side, ensure that three water level monitor devices measure the consistance of water level value.A set of deaerator level supervising device of the present utility model is installed, needs a ROSEMOUNT differential pressure transmitter, stainless-steel tube about the 15m of Φ 16.
Preferably, the water level signal that described first water monitor, the second water monitor and the 3rd water monitor record is sent to dcs (DCS), does 3 get 2 logical operations by dcs (DCS).The water level signal that first water monitor, the second water monitor, the 3rd water monitor record from deaerator storage tank is transported to DCS, and only have when the signal of two water level monitor devices all fluctuates larger, DCS just can make logical action.
The utility model installs the 3rd water level monitor device in the left side of deaerator storage tank periphery, and two water level monitor devices installed with right side, have three deaerator level signals to be sent to DCS altogether, do 3 get 2 logical operations by DCS.When one of them water level signal fault (bad point) or by mistake fluctuation display comparatively large (less) water level value time all will be rejected logical operation by DCS, false judgment is made according to wrong water level to prevent DCS interrelated logic, cause the stoppage in transit that equipment is unnecessary, ensure unit safety operation.
To sum up, a kind of deaerator level supervising device that the utility model proposes, cost is low, and greatly can increase the reliability of deaerator level signal, avoids its equipment failure caused of by mistake fluctuating, improves the operational reliability of equipment, ensures unit safety stable operation.
Below preferred implementation of the present utility model is described by reference to the accompanying drawings in detail; but; the utility model is not limited to the detail in above-mentioned embodiment; within the scope of technical conceive of the present utility model; can carry out multiple simple variant to the technical solution of the utility model, these simple variant all belong to protection domain of the present utility model.
