Description

Technical Field

[0001] The invention relates to the technical field of concentration detection alarms, in particular to a flue gas emission concentration detection alarm for yellow phosphorus production which can pretreat the flue gas. Background Art

[0002] Yellow phosphorus is a single element of phosphorus. It appears as a white or light yellow translucent solid. It is very soft and brittle at low temperatures, but its color darkens when exposed to light. When exposed to air, yellow phosphorus produces green phosphorescence and white smoke in the dark. Although insoluble in water, yellow phosphorus is slightly soluble in benzene and chloroform and readily soluble in carbon disulfide. In relatively humid air, its ignition point reaches 40 degrees Celsius, and in dry air it is slightly higher. Yellow phosphorus has a wide range of uses, such as in the production of phosphorus compounds such as thermal phosphoric acid, phosphorus trichloride, phosphorus oxychloride, and phosphorus pentasulfide, and as a raw material for the manufacture of organophosphorus pesticides and rodenticides such as trichlorfon, methyl parathion, chlorpyrifos, and dichlorvos. In addition, in the non-ferrous metal industry, yellow phosphorus can be made into phosphorus-copper alloys with copper, which is a very effective deoxidizer in the foundry industry. Flue gas used in yellow phosphorus production refers to waste gas generated during the yellow phosphorus production process. This flue gas mainly comes from the electric furnace process of yellow phosphorus production. When phosphate rock, coke, and silica are mixed and heated in a certain proportion to melt, tail gas is generated. The main components of this tail gas are CO (carbon monoxide), and it also contains CO2 (carbon dioxide), N2 (nitrogen), H2 (hydrogen), CH4 (methane), O2 (oxygen), H2S (hydrogen sulfide), P4 (white phosphorus), PH3 (phosphine), HF (hydrofluoric acid), and arsenic compounds. The composition of flue gas used in yellow phosphorus production may vary depending on the composition of raw materials such as phosphate rock and the production process. These flue gases usually contain harmful substances such as sulfides and smoke. Flue gas emission concentration detection and alarm are needed to monitor and alarm the flue gas produced by yellow phosphorus production to avoid harm to the environment and human body. In the "A Harmful Gas Concentration Alarm Device for Yellow Phosphorus Production Site" with the patent CN209149547U, a water washing cylinder is provided with a cavity inside the water washing cylinder, a containing cylinder is provided on one side of the water washing cylinder, a sedimentation chamber and a recovery chamber are provided inside the containing cylinder, an air suction fan is also provided on one side of the water washing cylinder, a plurality of carbon monoxide sensors are also provided on one side of the water washing cylinder, and a lime storage box is also provided on the containing cylinder. The utility model detects whether the carbon monoxide content in the room exceeds the standard in real time through the carbon monoxide sensor provided, and processes the toxic gas after it exceeds the standard, thereby solving the problem that the yellow phosphorus production process produces harmful gases, which seriously threatens human life and health; in addition, the lime storage box provided facilitates the treatment of waste liquid in the sedimentation chamber, thereby solving the problem that the general harmful gas concentration alarm device for yellow phosphorus production sites cannot process and recover toxic gases; In the "Yellow Phosphorus Production Flue Gas Treatment System" with the patent publication CN215996187U, a water curtain cabinet, a spray tower and an alkali washing tank are included. The side wall of the water curtain cabinet is provided with an air inlet pipe, the bottom is provided with a first water outlet pipe, the top is provided with a first air outlet pipe, the end of the first air outlet pipe extends from the side wall of the spray tower into the spray tower, the bottom of the spray tower is provided with a second water outlet pipe, and the top of the spray tower is provided with a second air outlet pipe, the end of the second air outlet pipe is provided with a first branch pipe and a second branch pipe, the first branch pipe and the second branch pipe extend into the first alkali washing tank and the second alkali washing tank respectively, and sodium hydroxide solution is provided in the first alkali washing tank and the second alkali washing tank; pH monitoring can be performed during NaOH solution washing to ensure the washing effect; In the patent application CN1132330A, "Method and Apparatus for Utilizing Yellow Phosphorus Tail Gas from Electric Furnace Production," low-pressure tail gas is collected from the phosphorus furnace's tail gas main water seal tank, purified in a water seal purifier, and then compressed by a compressor. After passing through a gas-water separator, a self-operated pressure regulator, a safety water seal, and a flame arrester, the gas is mixed with air blown in by the boiler's blast pipe in the tail gas burner and ejected out of the boiler for combustion. This method and apparatus offer advantages such as safety, reliability, energy conservation, and reduced environmental pollution, making it a safe and reliable waste gas utilization technology. However, when the yellow phosphorus fume concentration detection alarm is used to detect the fume concentration of yellow phosphorus production, most traditional detection alarms are installed separately at the same fixed position for detection, and cannot perform multi-angle detection of the yellow phosphorus fume concentration at different positions, thereby reducing the detection efficiency of the detection alarm; Therefore, we propose a flue gas emission concentration detection alarm for yellow phosphorus production that can pre-treat the flue gas in order to solve the above-mentioned problems. Summary of the Invention

[0003] The object of the present invention is to provide a flue gas emission concentration detection alarm for yellow phosphorus production that can pre-treat flue gas, so as to solve the problem raised in the above background technology that most traditional detection alarms on the market only install the detector alone in the same fixed position when detecting the yellow phosphorus flue gas concentration, and cannot perform multi-angle detection of the yellow phosphorus flue gas concentration at different positions, thereby reducing the detection efficiency of the detection alarm.

[0013] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0014] The present invention provides the following technical solutions: Embodiment 1, in order to solve the problem that the existing detection alarm cannot perform multi-angle detection, which leads to low detection efficiency of the detection alarm, discloses: The fuselage 1 has a control knob 2 rotatably mounted on the front left end thereof, and a control panel 3 is correspondingly mounted on the outside of the control knob 2, and the control panel 3 is screwed onto the front right end of the fuselage 1; It also includes: a fuselage 1, with grooves and sealed liquid inlet pipes 8 installed at both ends of its interior, and the outer ends of the two liquid inlet pipes 8 extend through the outside of both ends of the fuselage 1, and the two liquid inlet pipes 8 are sealed and connected to the spray plate 17 through hoses 18, and the two liquid inlet pipes 8 are symmetrically arranged about the vertical center line of the fuselage 1, and a turntable 4 is rotatably installed on the top of the fuselage 1, and the turntable 4 is circular, and a mounting plate 5 is screwed on the top of the turntable 4, and a detector 6 is installed on the outside of the mounting plate 5, and the detector 6 is connected to an alarm body 7 through a wiring harness, and the alarm body 7 is screwed on the upper right side of the fuselage 1; The fuselage 1 has a mounting motor 12 installed on its right side by a slotted screw, and the output end of the mounting motor 12 is connected to a worm 13, and the worm 13 is rotatably installed inside the fuselage 1, and the outer side of the worm 13 is engaged with a worm gear 19. The fuselage 1 has slots at both ends of its bottom through which a movable seat 16 is slidably installed, and the two movable seats 16 have the same structure, and the bottoms of the two movable seats 16 extend through and extend to the two ends of the bottom of the fuselage 1. At the same time, the bottoms of the two movable seats 16 are rotatably installed with spray discs 17, and the two spray discs 17 are both inclined.

[0015] The worm gear 19 is rotatably mounted inside the fuselage 1, and the internal slot of the worm gear 19 is penetrated by a transmission shaft 20, and the outer end of the transmission shaft 20 is penetrated by a first rotating gear 21, and the outer side of the first rotating gear 21 is meshedly connected with a transmission gear 22, and the internal slot of the transmission gear 22 is penetrated by a turntable 4.

[0016] like Figures 1-11 As shown, when it is necessary to perform multi-angle detection on the yellow phosphorus concentration in the flue gas, the motor 12 is started to drive the worm gear 19 meshingly connected to the outer side of the worm 13 to rotate, and then the worm gear 19 drives the first rotating gear 21 to rotate through the transmission shaft 20. At this time, the first rotating gear 21 simultaneously drives the turntable 4 connected to the inner side of the transmission gear 22 to rotate, and then drives the detector 6 installed above the turntable 4 to rotate 360 ​​degrees, thereby expanding the detection range of the detector 6, facilitating the subsequent multi-angle detection of the yellow phosphorus production flue gas concentration, and avoiding the phenomenon that the traditional detector 6 detects too single angles. As the turntable 4 rotates, the main drive gear 29 connected to the bottom of the turntable 4 will drive the auxiliary drive gear 30 to rotate, and then the auxiliary drive gear 30 will drive the moving rod 28 to rotate on the top of the fuselage 1 through a circle of gear blocks 31. At this time, the moving rod 28 will drive the driving fan 27 installed at its bottom to rotate, so as to better blow away and eliminate the yellow phosphorus smoke remaining inside the fuselage 1.

[0017] The second embodiment is different from the first embodiment in that the detector 6 can be quickly disassembled and replaced, and discloses: The mounting plate 5 has slots on both sides through which positioning plates 9 are slidably installed, and the two positioning plates 9 are in an inverted "L" shape, and the inner sides of the two positioning plates 9 correspond to the two sides of the detector 6, and the outer sides of the two positioning plates 9 are fitted with anti-slip pads 11, and the structure of the two anti-slip pads 11, and the outer sides of the two anti-slip pads 11 are fitted and connected to the two sides of the detector 6, the mounting plate 5 has slots on both ends inside which reset springs 10 are provided, and the structure of the two reset springs 10 is the same, and the outer ends of the two reset springs 10 are connected to the positioning plate 9.

[0018] like Figure 1-Figure 4 As shown, when the detector 6 needs to be quickly disassembled, assembled and replaced, it is only necessary to manually pull the two positioning plates 9 to move the position. At this time, the two positioning plates 9 can be separated from the detector 6, and then the detector 6 can be quickly disassembled, assembled and replaced, which is more time-saving and labor-saving. When the detector 6 needs to be quickly installed, it is only necessary to place the detector 6 on top of the mounting plate 5. At this time, the two reset springs 10 will automatically pop out the two positioning plates 9 to both sides of the detector 6 through their own elastic force. Then the two positioning plates 9 will increase the friction between the two positioning plates 9 and the detector 6 through the anti-slip pads 11, thereby avoiding the phenomenon of loosening and falling off of the detector 6 during use, thereby improving the stability of the detector 6 and making it more practical.

[0019] Example 3 is different from Example 2 in that the external sodium hydroxide liquid alkali can be evenly sprayed to the outside through two spray plates 17, thereby diluting the yellow phosphorus concentration in the flue gas. The fuselage 1 has a two-way screw rod 15 rotatably installed on the inner side of the bottom of the groove, and both sides of the two-way screw rod 15 are threadedly connected to a movable seat 16, and the right end of the two-way screw rod 15 is connected to the output end of the mounting motor 12 through a sprocket mechanism 14, and the rear sides of the two movable seats 16 are respectively installed with drive motors 23 by screws, and the output ends of the two drive motors 23 are respectively threadedly connected to a second rotating gear 24.

[0020] The bottom inner sides of the two movable seats 16 are grooved and rotatably mounted with second rotating gears 24. The two second rotating gears 24 have the same diameter, and the outer sides of the two second rotating gears 24 are meshed with half gears 25. The output ends of the two half gears 25 are wound and connected with torsion springs 26. The two torsion springs 26 have the same structure, and the outer ends of the two torsion springs 26 are connected to the second rotating gear 24. The interior of the two spray discs 17 are grooved and a movable plate 32 is slidably installed through them, and a row of ventilation holes 33 are evenly spaced inside the two movable plates 32, and two rows of empty slots 34 are corresponding to the outsides of the two rows of ventilation holes 33. At the same time, the two rows of empty slots 34 are evenly spaced at the bottom of the two spray discs 17. The interior of the two spray discs 17 are grooved and a movable plate 32 is slidably installed through a tension spring 36, and the outer ends of the two movable plates 32 are connected to pull ropes 35, and the outer ends of the two pull ropes 35 are connected to the two movable seats 16 through guide wheels.

[0021] like Figures 1-13 As shown, when the detector 6 detects that the concentration of yellow phosphorus fume is too high, the external sodium hydroxide liquid alkali is transported to the liquid inlet pipe 8, and then the two liquid inlet pipes 8 will transport the sodium hydroxide liquid alkali through the hose 18 to the two spray plates 17 for spraying and dilution, so as to avoid the dangerous phenomenon caused by the excessive concentration of yellow phosphorus fume. When the installation motor 12 rotates, the output end of the installation motor 12 will simultaneously drive the bidirectional screw rod 15 to rotate through the sprocket mechanism 14. At this time, the bidirectional screw rod 15 will simultaneously drive the two movable seats 16 to move back and forth left and right, so that the external sodium hydroxide liquid alkali can be stably sprayed to both sides of the bottom of the fuselage 1, thereby achieving the dilution of the yellow phosphorus tail gas concentration. When the two movable seats 16 are reciprocatingly moving left and right, the two driving motors 23 are started to drive the two second rotating gears 24 to rotate. At this time, the two second rotating gears 24 will also simultaneously drive the spray discs 17 connected to the output ends of the two half gears 25 to swing in position. Then, the two torsion springs 26 will elastically reset the positions of the two spray discs 17 after swinging, so that the two spray discs 17 can be swung back and forth to spray, thereby expanding the spraying range of the two spray discs 17 and improving the spraying efficiency of the two spray discs 17. When the two spray discs 17 swing to the moving angle, the two pull ropes 35 will pull the two movable plates 32 to move in position through the guide wheels, thereby driving the two rows of vents 33 and the empty slots 34 opened at the bottom of the two spray discs 17 to move, increasing the spraying pressure of the spray discs 17, so that the two spray discs 17 can be used for spraying more comprehensively, thereby completing a series of tasks.

[0022] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
