Description

Technical Field

[0001] The present invention relates to the technical field of furnace pressure auxiliary regulating devices, and in particular to an intelligent and convenient furnace pressure regulating device. Background Art

[0002] As the oxygen enrichment rate increases, the flue gas pressure of the heating furnace gradually decreases, because as the oxygen enrichment rate increases, the amount of flue gas in the furnace gradually decreases. When the cross-sectional area remains unchanged, the flow rate of the flue gas will decrease as the amount of flue gas decreases. Because the along-the-way resistance loss and local resistance loss of the flue gas flow are proportional to the square of the velocity, the along-the-way resistance loss and local resistance loss will also decrease accordingly. Therefore, under a certain oxygen enrichment rate, the flue gas pressure in the furnace will become a negative pressure, and cold air will be sucked into the furnace, which is detrimental to production. In order to adjust the furnace pressure, the flue damper is often closed or opened for adjustment. However, the existing device lacks a pressure oxygen enrichment detection structure and a linkage and synchronization design of the flue damper, and often requires manpower for detection and adjustment, resulting in a waste of manpower and low efficiency, and is not convenient for adjustment according to different closing speed requirements.

[0033] Working principle: through the connection between the outlet pipe 2 and the furnace, the gas in the furnace needs to flow through the outlet pipe 2 and the pressure oxygen enrichment detection structure 3. When the gas flows through the pressure oxygen enrichment detection structure 3, since the material of the zirconium oxide contact end 11 is doped with a small amount of CaO2 ZrO2 mixture, during the crystallization process, calcium ions enter the cubic crystal and replace the zirconium ions. Since the zirconium ion is +4 valence and the calcium ion is +2 valence, a calcium ion enters the crystal and only brings in one oxygen ion, while the replaced zirconium ion brings out two oxygen ions. As a result, an oxygen ion hole is left in the crystal, for example: zirconium oxide such as (ZrO2)0.85, (CaO2)0.15 (the molar fraction of zirconium oxide is 85%, and that of calcium oxide is 15%). The oxygen ion vacancies with a molar fraction of 7.5% form a good oxygen ion solid electrolyte. Together with the platinum electrode 12 and the platinum wire connected to the reaction tube 13 as a lead, an oxygen concentration difference cell is formed. The reference gas air with an oxygen partial pressure of p0 is introduced into the reaction tube 13 at one end of the cell; the measured gas with an oxygen partial pressure of p1 is introduced into the reaction tube 13 at the other end of the cell. Assuming p0>p1, at a high furnace temperature (650...850°C), oxygen will diffuse from the p0 side with a large partial pressure to the p1 side with a small partial pressure. This diffusion is not the process of oxygen molecules passing through the zirconia contact end 11 from the P0 side to the P1 side, but the process of oxygen molecules dissociating into oxygen ions and passing through the zirconia contact end 11. At a high temperature of about 750°C, oxygen will diffuse from the p0 side with a large partial pressure to the p1 side with a small partial pressure. This diffusion is not the process of oxygen molecules passing through the zirconia contact end 11 from the P0 side to the P1 side. Instead, it is the process of oxygen molecules dissociating into oxygen ions and passing through the zirconia contact end 11. At a high temperature of about 750°C, oxygen will diffuse from the p0 side with a large partial pressure to the p1 side with a small partial pressure. Under the action of, a reduction reaction occurs on the P0 side of the battery, and an oxygen molecule obtains 4 electrons from the platinum electrode, becomes two oxygen ions and enters the electrolyte, that is: 02(P0)+4e→202-P0 side platinum electrode is positively charged due to the large amount of electrons given, and becomes the positive electrode or anode of the oxygen concentration difference battery. After these oxygen ions enter the electrolyte, they move forward through the holes in the crystal to reach the platinum electrode on the right, and an oxidation reaction occurs on the P1 side of the battery. The oxygen ions release electrons on the platinum electrode and combine to form oxygen molecules and precipitate. The platinum electrode 12 is negatively charged due to the large amount of electrons obtained, and becomes the negative electrode or cathode of the oxygen concentration difference battery. In this way, an electric potential is formed on the two electrodes due to the accumulation of positive and negative charges, which is called the oxygen concentration difference electromotive force. When the two electrodes are connected into a circuit with a wire, the negative electrode The electrons on the positive electrode will flow to the positive electrode through the external circuit, and then supply oxygen molecules to form ions, and current will flow through the circuit. The size of the oxygen concentration difference electromotive force is related to the oxygen concentration in the gas on both sides of the zirconium oxide solid electrolyte. The data together with the pressure are introduced into the parameter calculation output module 15 through the pressure detection valve 14 to complete the final value comparison, and the parameter calculation output module 15 is electrically connected with the data receiving control module 17 to complete the output of the control command, and the transfer deduction of the data receiving control module 17 is used to complete the control of the control command again. When it is necessary to quickly complete the closing of the closing sliding plug 6 to achieve rapid pressure adjustment, the output of the output motor 18 is driven to complete the output transmission of the first output gear 20, the second output gear 21 and the third output gear 22.The stepper motor 24 is used to drive the threaded rod 25 to complete the output, and the displacement of the guide displacement plate 27 is completed through the limit matching of the guide displacement plate 27 and the limit light rod 26, so that the push follower rod 31 drives the displacement, and the flat speed transmission gear 35 is pushed out, so that the speed increase gear 34 and the second output gear 21 are meshed, and the transmission ratio increase principle of the large gear driving the small gear is used to increase the speed output, and the meshing of the follower output gear 37 and the driven gear shaft 29 is used to drive the high-speed rotation of the lifting output wheel 30, thereby completing the rapid lifting and lowering of the closing sliding plug 6. When low-speed closing is required, The sliding plug 6 avoids excessive pressure adjustment by driving the follower rod 31 to move so that the reduction gear 33 meshes with the first output gear 20, and the remaining speed-increasing gears 34 and the flat-speed transmission gear 35 do not mesh with the second output gear 21 and the third output gear 22. The transmission ratio reduction principle of the small gear drives the large gear to reduce the speed output. When stable opening or closing is required, the third output gear 22 meshes with the flat-speed transmission gear 35 to complete the steering change torque unchanged, achieve balanced speed transmission, complete stable speed output drive, and form a good and stable closed sliding plug 6 lifting drive.
