Description
Technical field
The utility model is related to desulfurizer, and specially a kind of desulfuration absorbing tower for steam power plant is for slurry circulation line.
Background technology
Wet desulphurization device is located at after end, the deduster of flue, due to being gas liquid reaction, its desulphurization reaction speed
Hurry up, efficiency high, sulfur-removing additives utilization rate it is high：When such as making desulfurizing agent with lime, as Ca/S=1, you can reach 70% desulfurization
Rate, is adapted to the flue gas desulfurization of large-scale coal fired power plant.In order to strengthen absorption process, improve desulfuration efficiency, reduce equipment investment and
Operating cost, desulfuration absorbing tower should possess the ability of continual and steady work.
Limestone slurry liquid case is used to be desulfuration absorbing tower for slurry.To avoid desulfuration absorbing tower limestone slurry liquid case entoplasm liquid from sinking
Form sediment, generally requiring the setting screw agitator in case makes slurries keep flowing.If screw agitator break down, it is necessary to
Repair time is long, while also causing to have a strong impact on for slurry to desulfuration absorbing tower, causes desulphurization system out of service.
The content of the invention
In order to solve the problems, such as screw agitator failure cause desulfuration absorbing tower cannot for slurry, the utility model proposes one
Desulfuration absorbing tower is planted for slurry circulation line.
Desulfuration absorbing tower of the present utility model is arranged between desulfuration absorbing tower and limestone slurry liquid case for slurry circulation line,
It is characterized in that the circulation line is made up of drain pipe road, feed liquid pipeline and circulating line；Drain pipe sets hydraulic pump on road
With the first valve, the second valve is set on feed liquid pipeline, the 3rd valve is set on circulating line；The drain pipe road and lime stone
Slurry tank bottom is connected, and feed liquid pipeline is connected with desulfuration absorbing tower, and circulating line is connected with lime stone slurry box top.
Drain pipe road is connected with lime stone slurry bottom portion, and feed liquid pipeline is connected with desulfuration absorbing tower, circulating line and stone
The connection of lime stone slurry tank top；When screw agitator normally runs, the first valve and the second valve are opened, close the 3rd valve
Door, slurries are extracted to desulfuration absorbing tower for starching from hydraulic pump；When screw agitator is stopped, the first valve and the are opened
Three valves, close the second valve, are extracted slurries by hydraulic pump and are fallen by circulating line outlet, force liquid circulation in case.
More preferably, flowmeter, described the second valve and the 3rd valve are set on described slurry pipeline and circulating line
Using electric control valve, described limestone slurry liquid case sets gravity sensor, by reading the data of gravity sensor, determines case
Interior slurries loop condition, the valve of manual control second and the 3rd valve balanced flow, while reaching liquid circulation in pressure case
Slurries are supplied to desulfuration absorbing tower.
The described desulfuration absorbing tower of limestone slurry liquid case at least two connection, circulating line outlet is respectively arranged at lime stone
Slurry tank top both sides, circulating line exit sets storage tank, and the bottom of storage tank sets the 4th valve, is installed under the 4th valve
Rotary water-out tap, it is ensured that liquid in the uniform agitation box of energy when slurries fall.
Desulfuration absorbing tower of the present utility model is for slurry circulation line, lime stone slurry when can ensure that screw agitator failure
Slurries forced circulation in case, maintenance cost is low, Stability Analysis of Structures reliability.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Wherein, drain pipe road 1, feed liquid pipeline 2, circulating line 3, the first valve 4, the second valve 5, the 3rd valve 6, water storage
Case 7, the 4th valve 8, rotary water-out tap 9.
Specific embodiment
Embodiment 1：The utility model is related to desulfurizer, specially a kind of desulfuration absorbing tower for steam power plant to be followed for slurry
Endless tube road, is arranged between desulfuration absorbing tower and limestone slurry liquid case, it is characterised in that the circulation line is by drain pipe road 1, feed flow
Pipeline 2 and circulating line 3 are constituted；Hydraulic pump and the first valve 4 are set on drain pipe road 1, the second valve is set on feed liquid pipeline 2
Door 5, sets the 3rd valve 6 on circulating line 3；Above-mentioned valve uses electric control valve.The drain pipe road 1 and lime stone slurry
Bottom portion is connected, and feed liquid pipeline 2 is connected with desulfuration absorbing tower, and circulating line 3 is connected with lime stone slurry box top.Limestone slurry
Liquid case sets gravity sensor.The desulfuration absorbing tower of limestone slurry liquid case at least two is connected, and the outlet of circulating line 3 is respectively arranged at
Lime stone slurry box top both sides, the exit of circulating line 3 sets storage tank 7, and the bottom of storage tank 7 sets the 4th valve 8, the 4th
Valve installs rotary water-out tap 98 times.
