Description
Technical field
The utility model relates to a kind of equipment utilizing blower fan to collect conveying yellow phosphoric tail gas completely.
Background technique
What current yellow phosphoric tail gas conveying adopted is that water ring vaccum pump carrys out pressurized delivered to downstream gas holder or use unit.
High by water ring vaccum pump pressurized delivered energy consumption, regulating power is poor, and pressure regulates and do not realize closed-loop automatic control, in order to ensure safety, must have certain yellow phosphoric tail gas emptying burning, cause the wasting of resources, pollute environment again.
The invention provides a kind of method and apparatus utilizing the complete pressurized delivered yellow phosphoric tail gas of blower fan, the method 100% recovery can collect conveying yellow phosphoric tail gas when yellow phosphorus electric furnace is normally produced, and resource recycling rate is high, and energy consumption is low, automatization level is high, easy and simple to handle.
Summary of the invention
Utilize blower fan to collect an equipment for conveying yellow phosphoric tail gas completely, utilize centrifugal blower to replace water ring vaccum pump that yellow phosphoric tail gas is collected pressurized delivered completely, be specially:
Collect and carry the equipment of yellow phosphoric tail gas, the outlet of tail gas water scrubber is connected with tempering tower through gas transmission line,
Tempering tower top is connected with gas fan through gas transmission line, and gas fan outlet is connected with surge tank through reflux pipeline, forms circulation loop.
Described gas fan is made up of two gas fans in parallel.
The gas transmission line that described gas fan is exported to surge tank is provided with return valve.Before gas fan,
After be provided with water seal.There is between water scrubber and surge tank the height difference of 3-5m.Surge tank is provided with intelligent pressure transmitter.Also be provided with yellow phosphoric tail gas supplying tube bottom tail gas water scrubber, this supplying tube be provided with voltage stabilizing water seal circulation loop, tail gas water scrubber and voltage stabilizing water seal form the height difference of 2-4 rice.
Yellow phosphoric tail gas through electric furnace out after, through water scrubber washing, entering surge tank, surge tank outlet docking blower fan import, fan outlet is received respectively to gas cabinet pipeline and the reflux pipeline to surge tank.Regulate the revolution of blower fan by frequency variator and regulate the aperture of reflux valve, making the Stress control of surge tank at about 300Pa.Reach close-loop automatic adjustment function, what whole tail gas that guarantee electric furnace produces were stable is transported to gas holder.
Yellow phosphoric tail gas is first by its solid impurity of two-stage washing removing, yellow phosphoric tail gas is by the fluctuation of surge tank smoothed pressure, yellow phosphoric tail gas replaces water ring vaccum pump pressurized delivered by gas fan, the redundant fashion of two is got in the Pressure testing employing three of yellow phosphoric tail gas, yellow phosphoric tail gas return valve adopts the efficient regulating butterfly valve of bias adding source of the gas amplifier, by the regulating liquid surface Altitude control yellow phosphoric tail gas surge tank superpressure upper limit, reach the situation that building the pressure does not appear in electric furnace.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 yellow phosphoric tail gas conveying schematic flow sheet.Wherein water scrubber (1), the total water seal of system (2), surge tank (3), gas fan (4), return valve (5), intelligent pressure transmitter (6), voltage stabilizing water seal (7), cut-out water seal (8).
Embodiment
embodiment 1
A kind ofly collect and carry the equipment of yellow phosphoric tail gas, tail gas water scrubber 1 exports and is connected through the total water seal 2 of gas transmission line and system, the total water seal 2 of system is connected with surge tank 3 through pneumatic tube, surge tank 3 top is connected with gas fan 4 through gas transmission line, gas fan 4 exports and is connected with surge tank 3 through reflux pipeline, forms circulation loop.
Described gas fan 4 is at least made up of two gas fans 4 in parallel.
The gas transmission line that gas fan 4 is exported to surge tank 3 is provided with return valve 5.
Forward and backward being provided with of gas fan 4 cuts off water seal 8.
There is between water scrubber 1 and surge tank 3 height difference of 3-5m.
Surge tank 3 is provided with intelligent pressure transmitter 6.
Also be provided with yellow phosphoric tail gas supplying tube bottom extra quality water scrubber 1, this supplying tube be provided with voltage stabilizing water seal 7 circulation loop, tail gas water scrubber 1 and voltage stabilizing water seal 7 form the height difference of 2-4 rice.
embodiment 2
When running as shown in Figure 1, open reflux valve, start blower fan, blower fan revolution is regulated by frequency variator, more slowly closing volume valve, when knock out drum pressure stability is after 300Pa, get rid of the water cutting off water seal, transporting system is communicated with electric furnace, more progressively closes atmospheric valve, yellow phosphoric tail gas is carried toward downstream by blower fan completely.
System is replaced by nitrogen, and sampling detects oxygen content lower than less than 0.2.Cut-out water seal is intake.
Yellow phosphorus electric furnace is stable, open the whole emptying of atmospheric valve, start water scrubber feeding spraying pump, reflux valve opens 100%, blower fan is started by frequency variator, frequency setting is at 30 hertz, reflux valve is closed to 42%, knock out drum pressure display 318Pa, discharge the water cutting off water seal, be communicated with yellow phosphorus electric furnace, progressively close electric furnace atmospheric valve, increase frequency converter frequency and closing volume valve simultaneously, after atmospheric valve cuts out completely, yellow phosphoric tail gas is just delivered to gas cabinet by blower fan completely, in order to ensure that system pressure is at about 300Pa, the frequency of frequency variator adjusts to 42 hertz, reflux valve aperture is probably 26%, pressure stability is at 340Pa.Regulate conversion switching over to automatic reflux valve, setting value is set to 320Pa, and realize PID and automatically regulate, pressure fluctuates all the time between 280Pa and 370Pa, highly stable.Substantially intervene and operation without operator.
