Background technology
Venturi scrubber is to take clear water into Venturi tube using pumping, caused dust in pickling production process, text
Washer needs constantly dissolving dust in mound, and solution concentration gradually increases, and after finite concentration is increased to, shower nozzle is just not
Misty liquid droplets, and the load increase of pump can be sprayed, causes pump to be stopped.Therefore, staff needs periodically to wash venturi
The liquid washed in device enters line replacement.When night shift or work easily produce carelessness compared with busy, cause not replace or replace it is not thorough, this
Sample can cause dust dedusting not thorough, and exhaust does not reach environmental requirement, also influence the whole service life of equipment in addition.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of Venturi scrubber changing liquid automatically system, Neng Goushi

On pressure transmitter is installed, moisturizing pond is connected by efferent duct, the pump housing and Venturi scrubber, and in efferent duct lower end, access is clear
Water pipe, water pipe are provided with the first motor-driven valve；The sedimentation basin other end is provided with discharge pipe, discharge pipe be provided with the second ball valve,
Second motor-driven valve.
Fluorine is lined with first ball valve, the first motor-driven valve, the second ball valve and the second motor-driven valve.
Parallel connection is provided with overflow pipe in addition on the discharge pipe, and overflow pipe connects with discharge pipe with holding tank.
First motor-driven valve, the second motor-driven valve circuit on be provided with the time relay.
A kind of Venturi scrubber changing liquid automatically system of the utility model, by using pressure transmitter, when liquid level is kept
When constant, fluid density can be changed, and pressure change is changed into using variable density, be detected through pressure transmitter and by signal
Corresponding controller is passed to, controller controls the first motor-driven valve, the second electronic valve timing feed liquor discharge opeing, so as to realize stable control
Dope in sedimentation basin processed carries out automatic controllable displacement.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and examples：
Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is the utility model motor-driven valve control schematic diagram.
In figure：Sedimentation basin 1, moisturizing pond 2, Venturi scrubber 3, scrubbing tower 4, the first ball valve 5, screen pipe 6, pressure inverting
Device 7, efferent duct 8, the pump housing 9, water pipe 10, the first motor-driven valve 11, discharge pipe 12, the second ball valve 13, the second motor-driven valve 14, overflow
Pipe 15, holding tank 16.
Embodiment
As shown in Figure 1-2, a kind of Venturi scrubber changing liquid automatically system, including sedimentation basin 1, moisturizing pond 2, sedimentation basin 1
It is interconnected between upper end and Venturi scrubber 3, scrubbing tower 4, it is not complete after centrifuge washing is atomized by Venturi scrubber
The dusty gas combined entirely drives in the wrong direction and washed again by scrubbing tower, so as to which dust is cleared., can be heavy in order to avoid shower nozzle blocks
The side of shallow lake pond 1 is separately provided a moisturizing pond 2, and moisturizing pond 2 is connected with sedimentation basin 1 by the screen pipe 6 of the first ball valve of band 5
Connect.Pressure transmitter 7 is installed in moisturizing pond 2, solution concentration changes after pressure transmitter 7 can experience washing, and by pressure
Transmitter 7 is arranged in the moisturizing pond 2 being independently arranged, and is negative pressure mainly due to Venturi tube inside, due to easy in airduct
Sedimentating dust, negative pressure variation is larger, if therefore being set directly on sedimentation basin by pressure transmitter and can bring larger mistake to measurement
Difference.The moisturizing pond 2 is connected by efferent duct 8, the pump housing 9 with Venturi scrubber 3, the termination of efferent duct 8 and Venturi scrubber 3
Junction is provided with paired shower nozzle.Water pipe 10 is accessed in the lower end of efferent duct 8, water pipe 10 is provided with the first motor-driven valve 11；It is described
The other end of sedimentation basin 1 is provided with discharge pipe 12, and discharge pipe 12 is provided with the second ball valve 13, the second motor-driven valve 14.
Fluorine is lined with first ball valve 5, the first motor-driven valve 11, the second ball valve 13 and the second motor-driven valve 14.I.e. first
Ball valve 5, the second ball valve 13 are Fluorine-lined ball valve, and the first motor-driven valve 11, the second motor-driven valve 14 are Fluorine-lined motor-driven valve.It can so avoid
Corroded in acid cleaning process.
Parallel connection is provided with overflow pipe 15 in addition on the discharge pipe 12, and overflow pipe 15 connects with discharge pipe 12 with holding tank 16
It is logical.Thereby guarantee that the liquid level in sedimentation basin 1 is in same position all the time, condition is provided for detection.
First motor-driven valve 11, the second motor-driven valve 14 circuit on be provided with the time relay.Due to water pipe 10 with
The diameter of discharge pipe 12 is different, and input flow velocity is different, inputs 10 a diameter of 50mm of water pipe under normal circumstances, and discharge pipe 12 is
150mm, i.e. clear water input quantity are far smaller than discharge rate, not only can be to sedimentation basin 1 by the way that efflux time is controlled at the appointed time
Interior water is preferably controlled, and avoids the dilutional hyponatremia of sedimentation basin 1 from discharging, water source cannot utilize well.Also realize in addition
When concentration is less than a certain value, liquid level remains constant, is so advantageous to complete stably measured by pressure transmitter 7 and controls
（After sedimentation basin dilutional hyponatremia is discharged, when concentration is less than a certain value, liquid level does not reach original liquid level）.
Operation principle and process：When pressure transmitter detects that pressure reaches setting value, the first motor-driven valve 11 works, and adds
Enter clear water, shower nozzle is rinsed by the pump housing 9；The second motor-driven valve 14 acts simultaneously, discharges high concentration liquid.Replace to liquid
Concentration stops the first motor-driven valve 11 after reaching pickling requirement, the second motor-driven valve 14 works, and changes liquid and terminates.
