Abstract
The utility model discloses a kind of mist separator of desulfurization flushing valve set control system, comprise technique water tank, described technique water tank connects demister by water-supply-pipe, and described water-supply-pipe is provided with flushing pump and mist eliminator flushing valve group; Described mist eliminator flushing valve group comprises upper, middle and lower three parallel branches, each branch road is all provided with the flushing valve of multiple series connection; The action executing of each flushing valve is corresponding to a Control, and each relay is connected to the output point of a PLC.The utility model control structure is simple, adopts the relay of output point to each flushing valve of PLC to control accordingly, the switch that flushing valve can be made orderly by rational control method.Adopting two cover flushing pumps, is that the normal work of system is protected.
Description
Technical field
The utility model relates to a kind of mist separator of desulfurization flushing valve set control system.
Background technology
Flue gas desulfurization refers to remove oxysulfide (SO from flue gas or other industrial waste gases
2and SO
3).Flue gas desulfurization (Flue gasdesulfurization is called for short FGD), in FGD technology, divides by the kind of desulfurizing agent, can be divided into following Lung biopsy: with CaCO
3calcium method based on (lime stone), the magnesium processes based on MgO, with Na
2sO
3based on sodium method, with NH
3based on ammonia process, the organic alkaline process based on organic base, generally uses calcium method; By absorbent and desulfurization product, desulfur technology can be divided into again wet method, dry method and half-dried (half is wet) method by the dry and wet state in sweetening process, generally uses wet method.Mist separator of desulfurization needs the carrying out of regularly fixed point to clean, and must be equipped with a set of effective control system, make mist separator of desulfurization flushing valve group obtain orderly control.
Utility model content
The purpose of this utility model is exactly to solve the problem, a kind of mist separator of desulfurization flushing valve set control system is provided, the comparator of PLC and integer function is adopted to control, avoid disappearing because open and close put in place and causing the paralysis of whole flushing valve group, even if single valve cannot perform an action or open and close put in place blackout, the sequentially-operating of valve group also can perform down, can't affect the flushing work of whole valve group because of single valve.
To achieve these goals, the utility model adopts following technical scheme:
A kind of mist separator of desulfurization flushing valve set control system, comprise technique water tank, described technique water tank connects demister by water-supply-pipe, and described water-supply-pipe is provided with flushing pump and mist eliminator flushing valve group;
Described mist eliminator flushing valve group comprises upper, middle and lower three parallel branches, each branch road is all provided with the flushing valve of multiple series connection; The action executing of each flushing valve is corresponding to a Control, and each relay is connected to the output point of a PLC.
Every bar branch road is all provided with 6 flushing valves.
Described flushing pump is provided with two, and one is main flushing pump, and one is flushing pump for subsequent use, and two flushing pumps are connected in parallel on aqueduct.
The beneficial effects of the utility model: the utility model control structure is simple, adopt the relay of output point to each flushing valve of PLC to control accordingly, the switch that flushing valve can be made orderly by rational control method.Adopt two cover flushing pumps, the normal work of system is protected.Each valve is fixing to a cleaning, can contain all positions of demister, complete the cleaning to demister; Two flush water pumps due to this system disposition, accomplished the using and the reserved, that more insures completes water delivery operation.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Wherein, 1. demister, 2. mist eliminator flushing valve group, 3. flushing pump, 4. technique water tank.
Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
As shown in Figure 1, a kind of system adopting mist separator of desulfurization flushing valve group control method, comprises technique water tank 4, and described technique water tank 4 connects demister 1 by water-supply-pipe, and described water-supply-pipe is provided with flushing pump 3 and mist eliminator flushing valve group 2;
Described mist eliminator flushing valve group 2 comprises upper, middle and lower three parallel branches, each branch road is all provided with the flushing valve of multiple series connection; The action executing of each flushing valve is corresponding to a Control, and each relay is connected to the output point of a PLC.
Every bar branch road is all provided with 6 flushing valves, comes to 18 flushing valves.
Described flushing pump establishes 3 to have two, and one is main flushing pump, and one is flushing pump for subsequent use, and two flushing pumps 3 are connected in parallel on aqueduct.
When flushing valve group receives startup command, the first flushing valve is opened, first counter and per second the adding up of the second counter add 1, when equaling nT1 when the first counter counts, PLC output point gives the (n+1)th flushing valve open command, give the n-th flushing valve shutdown command simultaneously, wherein T1 be setting the time interval, T1 be not equal to 0 natural number; N is greater than the natural number that 0 is less than N, and N is total number of flushing valve; When being more than or equal to the time T2 of setting during the second counter counts, the duty of main flushing pump and flushing pump for subsequent use switches, and one becomes stopping from operation, and one becomes operation from stopping.
By reference to the accompanying drawings detailed description of the invention of the present utility model is described although above-mentioned; but the restriction not to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various amendment or distortion that creative work can make still within protection domain of the present utility model.
