Description
Technical field
The utility model belongs to power plant desulfurization technical field, and in particular to a kind of pulp feeding system trouble hunting compensation is for slurry
System.
Background technology
Pulp feeding system is mainly used in the desulfurization of thermal power plant to absorption tower, AFT towers (the outer stock tank of desulfurizing tower) supply
Lime stone slurry, pH value in control tower, achievees the purpose that scrubbing CO_2.
But when phenomena such as pulp feeding system generation pipe leakage, blocking, slurry supply pump failure and failsafe valve, due to it
Repair time is long, easily leads to problems such as environmentally friendly parameter exceeded.
Utility model content
The shortcomings that the purpose of the utility model is to overcome the prior arts provides a kind of pulp feeding system trouble hunting compensation confession
Slurry system, the technical issues of solving in existing pulp feeding system maintenance process easily to occur environmentally friendly parameter exceeded phenomenon.
In order to solve the above technical problems, the technical solution adopted in the utility model is：
A kind of pulp feeding system trouble hunting compensation pulp feeding system, wherein：Including spare flow inlet and wash tub pipe；
The import of the spare flow inlet is connect with lime stone slurry-supplying can, outlet and the accident slurries of the spare flow inlet
The inlet tube connection for returning to pump is equipped with first butterfly valve in the spare flow inlet close to inlet end, and the spare flow inlet leans on
Nearly exit end is equipped with second butterfly valve, and blow-off pipe is equipped in the middle part of the spare flow inlet, and the blow-off pipe is equipped with rapid pollution discharging
Valve；
The spare flow inlet that one end of the wash tub pipe and first butterfly valve export side is connect, the wash tub pipe it is another
One end is connect with the spare flow inlet of second butterfly valve inlet side, and water inlet, the water inlet are equipped in the middle part of the wash tub pipe
It is connect with flushing water water inlet pipe；The both ends of the wash tub pipe are respectively equipped with the first diaphragm valve and the second diaphragm valve.
The setting of spare flow inlet in the utility model, can be in pulp feeding system maintenance process so that the slurry in slurry tank
Liquid returns to pump by accident slurries and enters in absorption tower, ensure that the reliability service of pulp feeding system, avoids appearance and is led by maintenance
Cause the generation of the exceeded phenomenon of environmental protection；The setting of wash tub pipe, can be after maintenance completion, spare flow inlet deactivate, to spare for slurry
Inside pipe wall is rinsed, and the sewage after flushing can be discharged by blow-off pipe, and the utility model can not only fundamentally ensure for slurry system
System reliability operation, moreover it is possible to avoid the risk for causing environmentally friendly parameter exceeded because of pulp feeding system defect, be the safe and stable fortune of equipment
Row provides reliable guarantee.Compared with prior art, the utility model has simple in structure, at low cost, easy promote, safely, surely
The advantages that fixed, reliable.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
The utility model is described in further detail with reference to the accompanying drawings and examples.
As shown in Figure 1, a kind of pulp feeding system trouble hunting in the present embodiment compensates pulp feeding system, wherein：Including spare
Flow inlet 1 and wash tub pipe 2；
The import of the spare flow inlet 1 is connect with lime stone slurry-supplying can, and outlet and the accident of the spare flow inlet 1 are starched
Liquid returns to the inlet tube connection of pump, and first butterfly valve 4 is equipped with close to inlet end in the spare flow inlet 1, described spare for slurry
Pipe 1 is equipped with second butterfly valve 5 close to exit end, and 1 middle part of the spare flow inlet is equipped with blow-off pipe 3, and the blow-off pipe 3 is equipped with
Quick draining valves 6；
The spare flow inlet 1 that one end of the wash tub pipe 2 exports side with first butterfly valve 4 is connect, the wash tub pipe 2
The other end connect with the spare flow inlet 1 of 5 inlet side of second butterfly valve, the middle part of the wash tub pipe 2 is equipped with water inlet, described
Water inlet is connect with flushing water water inlet pipe 9；The both ends of the wash tub pipe 2 are respectively equipped with the first diaphragm valve 7 and the second diaphragm valve
8。
The utility model application method and operation principle are：
When phenomena such as pipe leakage, blocking, slurry supply pump failure and failsafe valve occurring for pulp feeding system, first is opened simultaneously
Butterfly valve 4 and second butterfly valve 5, the slurries in slurry tank can flow into accident slurries by spare flow inlet 1 and return to pump, and pass through accident
Slurries return to pump and enter in absorption tower, ensure that normally for slurry；
After the completion of maintenance, first butterfly valve 4 and second butterfly valve 5 are closed, the first diaphragm valve 7, the second diaphragm valve 8 are opened simultaneously
It is respectively enterd in spare flow inlet 1 by 2 both ends of wash tub pipe with the water of quick draining valves 6, flushing water water inlet pipe 9, to spare confession
Slurry 1 inner wall of pipe be rinsed, the sewage after flushing is discharged by blow-off pipe 3, closed after rinsing well the first diaphragm valve 7, second every
Film valve 8 and quick draining valves 6.
