The advantages of a kind of desulfurizer mist eliminator provided by the invention rinses control system is: convenient and fast by control module
The purpose regulated and controled to the spray head at the different height of desulfurizing tower inside is realized, ensure that the cleaning effect of demister, and energy
It enough assists determining pipeline abnormal position by the numerical value of flowmeter and pressure gauge, reduces the labor intensity of staff, have
It is good to push away prospect.
Detailed description of the invention
Fig. 1 is a kind of schematic diagram of desulfurizer mist eliminator rinse-system provided by the embodiment of the present invention；
Fig. 2 is a kind of control module schematic diagram of desulfurizer mist eliminator rinse-system provided by the embodiment of the present invention.
Specific embodiment
To make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with specific embodiment, and reference
Attached drawing, the present invention is described in further detail.
As shown in Figure 1, a kind of desulfurizer mist eliminator flushing control device, including skid module (not shown) and control module
2；The skid module is used to supply water respectively in the spray head 3 of different height inside desulfurizing tower (not shown), the control mould
The frequency that block 2 fitted to be the time for the opening continuous work of spray head 3 that can control different height and opening works.To
The purpose carried out automatically controlling to the working time of the spray head 3 at different height and frequency is realized, reduces staff's
Labor intensity.
The skid module includes main pipe 11 and multiple branch pipes 12 for connecting respectively with main pipe 11, and each 12 end of branch pipe connects
It is connected to the spray head 3.It include valve 13, filter 14, flowmeter 15 and pressure in the main pipe 11 along flushing water flow direction
Meter 16；The valve 13 can close main pipe 11, and valve 13 can be automatically opened or be opened manually by staff；Filtering
Device 14 is preferably Y-filter, for the impurity in excessively water, prevents spray head 3 from blocking, the flowmeter 15 is for obtaining main pipe
11 flow, pressure gauge 16 are used to obtain the hydraulic pressure of main pipe 11.In preferred embodiment, the flowmeter 15 is electromagnetic flowmeter,
Pressure gauge 16 is pressure transmitter.
Manifold valve 4 is additionally provided on the branch pipe 12, the control module 2 includes the control communicated to connect with manifold valve 4
Device 21, the controller 21 is used to control the frequency of time and unlatching that manifold valve 14 continuously opens, to control the work of spray head 3
Make time and frequency.Controller 21 is preferably PLC controller, controls the manifold valve 4 on each branch pipe 12 respectively by PLC program
Opening and closing, realize to the accuracy controlling of the spray head 3 at different height in desulfurizing tower.
With reference to Fig. 2, manifold valve 4 described in preferred embodiment is set as Pneumatic valve, and control module 2 further includes and the branch pipe
The pressure stabilizing air accumulator 22 and the pressure regulation filter (not shown) being connect with pressure stabilizing air accumulator 22 that valve 4 connects, pressure regulation filter
Pressure value is arranged to 0.2~0.4Mpa, by pressure regulation filter into the pressure and tune of such as compressed gas of pressure stabilizing air accumulator 22
The pressure value for pressing through filter setting is identical, and pressure stabilizing air accumulator 22 can store at least 3L gas, to provide air pressure for manifold valve 4
Turn on, and can the gas circuit before pressure stabilizing escape pipe 22 when something goes wrong, by being stored in pressure stabilizing escape pipe 22
Compressed gas guarantees the normal work of manifold valve 4 within a certain period of time, reduces influence of the unit exception to normally producing.
Desulfurizer mist eliminator flushing control device provided by the utility model can also ancillary staff to wash tub pipe
The exception on road is positioned；Concrete mode are as follows: 1) during the rinsing process, flow is lower if 11 pressure of main pipe is higher, can
Tentatively judge that blocking occurs at least one branch, can generally directly determine that be that at least one spray head in desulfurizing tower occurs stifled
Plug, successively opening the manifold valve 4 on different branch pipes 12 at this time can determine that existing abnormal position；20 work as the pressure of main pipe 11
When lower and flow is higher, it can tentatively judge that at least one branch leaks, it at this time can also be by successively opening different branch
Manifold valve 4 on pipe 12 is positioned；3) 11 pressure of main pipe and when lower flow, can tentatively judge the water route before main pipe 11
There is leakage.
Particular embodiments described above has carried out further in detail the purpose of the present invention, technical scheme and beneficial effects
It describes in detail bright, it should be understood that the above is only a specific embodiment of the present invention, is not intended to restrict the invention, not
