Embodiment
Incorporated by reference to shown in Fig. 1 to Fig. 3; a kind of anti-stop-type flue gas accident sprinkling system of the utility model protection; it comprises spray pipeline system, and this spray pipeline system comprises the spray being arranged at above flue and drenches female pipe 1, and this spray is drenched and established some nozzle 2 and at least one shut-off valve of stretching into flue on female pipe 1. Protection of the present utility model focuses on; also comprise the oven dry air pipe line system for drying; this oven dry air pipe line system comprises the first shut-off valve 6 drying air pipe line 5 and upper setting thereof, dries air pipe line 5 and accesses the female pipe 1 of spray pouring, and oven dry wind can be sent into the female pipe 1 of spray pouring and nozzle 2 by it. The temperature control drying wind is between 100-200 DEG C, and the oxidation wind that oven dry wind can quote 150 DEG C, thermal power plant Nei mono-tunnel nearby dries the female pipe 1 of spray pouring and nozzle 2, can avoid the cost providing separately the generation of wind source.
Use and practice situation according to reality, as shown in Figure 2, female pipe 1 two ends are drenched in spray can supply spray water to best embodiment simultaneously, in this kind of embodiment, shut-off valve is the first shut-off valve 3 and the 2nd shut-off valve 4 that spray drenches that female pipe 1 two ends are arranged respectively, and it connects different water supply lines respectively.
Spray is drenched and is established at least one under meter 7 on female pipe 1, thus calculate water spray, and the air output drying wind is set according to water spray, best embodiment is as shown in Figure 2, outside first, second shut-off valve, respectively establish a under meter, the object more accurately adding up water spray can be reached. The flue end face of nozzle 2 upstream and downstream is established and is at least respectively established 3 tensimeters 8, falls in order to detect the pressure of nozzle 2 upstream and downstream.
For increasing spray area, spray is drenched parallel connection at least one can spray shower pipe 11 on female pipe 1, as shown in Figure 2, every root spray shower pipe 11 all can be established 2 nozzles 2 stretching into flue and arranging, the flue end face of the upstream and downstream of nozzle establishes 3 tensimeters, and these 3 tensimeters can be separately positioned on the upstream and downstream relative to 2 nozzles and mid-way.One oxidation wind of 150 DEG C can quoted nearby in thermal power plant when drying operation is dried spray and is drenched female pipe 1, spray shower pipe 11 and nozzle 2.
Above-mentioned first shut-off valve 6, the 2nd shut-off valve 3, the 3rd shut-off valve 4, under meter 7 are all connected with Controlling System with tensimeter 8, this spray pouring, drying course are carried out omnidistance data monitoring by this Controlling System, and it can select DCS Controlling System or other existing Controlling System.
Based on said structure, it it is below the use procedure of most preferred embodiment of the present utility model.
During actual use, the 2nd shut-off valve 3 one end that female pipe 1 is drenched in spray connects plant area's hydrant pipe, the 3rd shut-off valve 4 one end connection mist eliminator flushing water pipe, it may be achieved other programs produce the recycle of water. When spray is drenched, opening the 2nd shut-off valve 3 and the 3rd shut-off valve 4, drench female pipe 1 from two ends plant area hydrant pipe and mist eliminator flushing water pipe to spray and intake, water sprays from nozzle 2. In the process that spray is drenched, flow signal and opening and closing time are sent to DCS Controlling System by the under meter 7 at two ends, to calculate water spray, and arrange air output accordingly.
After accident spray pouring terminates, DCS Controlling System sends signal and closes the 2nd shut-off valve 3 and the 3rd shut-off valve 4, stop the supply of spray water, and send signal and the first shut-off valve 6 is opened, lead to and pass through, into one, the high-temperature cleaning oxidizing gas filtered, temperature is in about 150 DEG C, and this high warm air can dry rapidly moist nozzle 2, thus reaches the useful effect avoiding nozzle 2 to adhere to dust in flue gas. Meanwhile, the pressure of 3 tensimeters detection nozzle upstream and downstream falls and data sends to DCS Controlling System, when pressure fall tend towards stability time then DCS Controlling System send signal and cut off air intake.
The utility model increases, after accident spray is drenched, the mode led to into oven dry wind, the problem of spray spout of effectively preventing accident blocking, improve stability and the reliability of desulphurization system, all can normally start guarantee accident sprinkling system has an accident at boiler systems, desulphurization system breaks down, and safe operation.
