Description
Technical field
The utility model relates to wet desulfuration tower technical fields, and in particular to a kind of wet desulfuration tower slurries overflow is remotely supervised
Examining system.
Background technique
Energy resource structure of the China based on coal will not change within the long duration, therefore, control coal-fired flue-gas SO2Discharge
It is an important process of China's control atmosphere pollution.Currently, the coal unit of 90% or more the country is using lime stone-stone
Cream wet desulfurizing process, such as application No. is 201410819201.4 Chinese patents.Wet desulfuration tower in the process of running, due to
The inert substance (waste water, oil, heavy metal etc.) of the entrainments such as flue gas, lime stone slurry, process water recycles for a long time in desulfurizing tower
Accumulation forms foam or operations staff's misoperation, causes slurries pit level to be higher than overflow liquid level, there are desulfurizing tower overflows
Risk.Especially when overflow occur when, due to operator on duty apart from device context farther out, can not discovery promptly and accurately ask
Topic, causes a large amount of slurries to leak, adversely affects to peripheral equipment and environment, seriously jeopardize entire wet desulfurization system
Safe and stable operation, while also influencing Business Economic Benefit and environmental benefit.
Utility model content
The purpose of the utility model is to overcome the above deficiencies in the existing technologies, and provide a kind of structure it is simple,
Stable, investment wet desulfuration tower slurries overflow remote supervision system low with operating cost, strong operability, for judging
Whether slurries occur overflow, realize long-range monitoring.
The technical scheme in the invention for solving the above technical problem is: a kind of wet desulfuration tower slurries overflow is remotely supervised
Examining system, including wet desulfuration tower, which is characterized in that further include overflow pipe, flusher, temperature measuring device, flow measurement
Device, slurries discharger and warning device；One end of the overflow pipe is connect with wet desulfuration tower, the overflow pipe it is another
End is connect with slurries discharger；The flusher, temperature measuring device and flow measurement device are arranged on overflow pipe,
The temperature measuring device and flow measurement device are connect with warning device.By overflow down-comer arrange a sleeving temperature and
Flow measurement device judges whether slurries occur overflow, realizes long-range monitoring for monitoring the instantaneous spillway discharge of slurries.
Furthermore, the flusher, temperature measuring device and flow measurement device are sequentially arranged on overflow pipe.
Flow measurement device is used to measure the instantaneous excess flow of slurries, judges whether wet desulfuration tower occurs by analysis instantaneous flow
Slurries overflow, flow measurement device are arranged on overflow down-comer.
Furthermore, the warning device is connected in wet desulphurization DCS control system, realizes long-range monitoring.
A kind of monitoring method of wet desulfuration tower slurries overflow remote supervision system as described above, which is characterized in that institute
It is as follows to state monitoring method: the foam or slurries that wet desulfuration tower overflows successively are measured through excess temperature and are filled by overflow pipe
It sets and flow measurement device；Flow measurement device monitors the instantaneous flow of slurries, when instantaneous flow measured value is in 0-5m3/ h range
When, judgement has minimal amount of slurries outlet in the form of overflow of blistering, at this time without alarm；When instantaneous flow measured value is greater than
5m3/ h, and when temperature measuring device is shown more than 40 DEG C, then judgement is there are slurries overflow phenomena, and warning device is reported at this time
It is alert, and notify the timely emergency action of operator on duty.
Furthermore, temperature change in the temperature measuring device measurement down comer duct；Under normal running (operation) conditions, temperature
Degree is shown as environment temperature, when there is a large amount of slurries overflow, measures the slurry temperature of overflow, displays temperature then significantly increases；
In such a way that this is as the subsidiary for judging whether to occur slurries overflow.
Furthermore, flusher is periodically rinsed temperature measuring device and flow measurement device, prevents overflow
Pipe, temperature measuring device and flow measurement device fouling blockage.The service life of each device can be extended.
Furthermore, it when slurries overflow occurs for flow measurement device judgement, is issued and is reported by wet desulphurization DCS control system
Alert signal realizes long-range monitoring.
The utility model compared with prior art, has the following advantages that and effect: it is simple that the utility model monitors process, throws
, strong operability low with operating cost is provided, there is applicability to the judgement of wet desulfuration tower flooding problems, therefore there is good ring
Guarantor and economic benefit, and be with a wide range of applications.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of wet desulfuration tower slurries overflow remote supervision system in the utility model embodiment.
Fig. 2 is the partial enlarged view in Fig. 1 at A.
In figure: wet desulfuration tower 1, overflow pipe 2, flusher 3, temperature measuring device 4, flow measurement device 5, slurries
Cheat 6, warning device 7.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing and by embodiment, and following embodiment is pair
The explanation of the utility model and the utility model is not limited to following embodiment.
Embodiment.
Referring to Fig. 1 to Fig. 2, a kind of wet desulfuration tower slurries overflow remote supervision system, including wet desulfuration tower 1, overflow
Pipe 2, flusher 3, temperature measuring device 4, flow measurement device 5, slurries melt pit 6 and warning device 7.
One end of overflow pipe 2 is connect with wet desulfuration tower 1, and the other end of overflow pipe 2 is connect with slurries melt pit 6；Rinse dress
It sets 3, temperature measuring device 4 and flow measurement device 5 is successively set on overflow pipe 2, temperature measuring device 4 and flow measurement dress
It sets 5 to connect with warning device 7, warning device 7 is connected in wet desulphurization DCS control system, realizes long-range monitoring.
The monitoring method of above-mentioned wet desulfuration tower slurries overflow remote supervision system is as follows: wet desulfuration tower 1 overflows
Foam or slurries by overflow pipe 2, successively pass through temperature measuring device 4, flow measurement device 5, flow measurement device 5 is supervised
The instantaneous flow for surveying slurries, when instantaneous flow is greater than 5m3When/h, and when 4 displays temperature of temperature measuring device is more than 40 DEG C, it can sentence
It is disconnected to have a large amount of ororrhea outflow desulfurizing towers, warning device 7 is triggered, operator on duty carries out emergency action to the flooding problems；Work as wink
Shi Liuliang is less than 5m3When/h, and when temperature is without significant change, it can determine whether as no overflow or blistering overflow, the wind of slurries overflow
Danger is smaller, and without triggering warning device 7, the slurries finally overflowed drain into melt pit 6.To prevent slurries in overflow pipe 2 and surveying
It is condensed on amount device, needs timing to open flusher 3 and overflow pipe 2 is rinsed.
Although the utility model is disclosed as above with embodiment, its protection scope being not intended to limit the utility model,
