Description

Technical Field

[0001] The invention relates to the technical field of automobile exhaust treatment liquid production, in particular to a preparation device and a preparation method of automobile exhaust treatment liquid containing cerium. Background Art

[0002] Automobile exhaust is the waste gas generated when the car is in use. It contains hundreds of different compounds, among which pollutants include solid suspended particles, carbon monoxide, carbon dioxide, hydrocarbons, nitrogen oxides, lead and sulfur oxides. While exhaust directly endangers human health, it also has a profound impact on the environment in which humans live. The sulfur dioxide in the exhaust has a strong irritating odor. When it reaches a certain concentration, it is easy to cause "acid rain", causing soil and water acidification, affecting the growth of crops and forests. As one of the main sources of air pollution, motor vehicle exhaust contains a large amount of harmful substances. Due to the serious dispersion and mobility of automobile operation, it brings certain limitations to purification and treatment technology. In addition to developing in-machine purification technology, we must also vigorously develop out-of-machine purification and treatment technology. This should be There are two aspects to start with: one is control technology, which is mainly to improve the combustion rate of fuel, install anti-pollution treatment equipment and develop new engines; the other is administrative management means, adopt scrapping and updating, eliminate old cars, develop new cars, and start with controlling fuel use standards. When high-temperature automobile exhaust passes through the purification device, the purifier in the three-way catalytic converter will enhance the activity of the three gases CO, HC and NOx, and promote them to undergo certain oxidation-reduction chemical reactions, among which CO is oxidized at high temperature to become colorless, non-toxic carbon dioxide gas; HC compounds are oxidized at high temperature to become water and carbon dioxide; NOx is reduced to nitrogen and oxygen, and the three harmful gases become harmless gases, so that the automobile exhaust can be purified. Cerium-containing automobile exhaust treatment fluid is often used for reduction treatment operations.

[0003] For example, the patent document with announcement number CN 102019192 B discloses a process for oil-free cerium carbonate for automobile exhaust purification catalyst, which specifically comprises the following steps: the cerium chloride solution separated in the extraction tank and the ammonium bicarbonate solution obtained after dissolution are respectively pumped into a high-level tank to control the flow rate to 5-8m3 / s, and then flow into a chemical fiber filter column through the high-level tank, the fiber loading volume is 70-80%, the column volume is φ500×2000, the filtered solution flows into a receiving tank, and then pumped into a high-level tank for standby; the cerium chloride solution is added to a 20m3 precipitation tank, the volume is 1.6×1.8m3, and contains 500-600kg of rare earth. After adding 100-200mL JU-cleaning agent, the concentration of the feed liquid is adjusted to 40-80g / L, and ammonium bicarbonate solution is slowly added during stirring, with a concentration of 80-100g / L, a flow rate of 3-5m3 / s, and a precipitation temperature of 40-80°C. After the reaction is complete, the stirring is stopped, and the solution is centrifuged and dried after settling, and rinsed with JU-cleaning agent for several times. When the pH value reaches 6-7, an oil-free cerium carbonate product can be obtained, which can be directly used to prepare rare earth carbonates for automobile exhaust purification catalysts, thereby achieving the effect of removing oil stains and ensuring that the produced products do not contain any oil stains.

[0004] However, in the actual use of this structure, it is often only possible to adopt a direct mixing method to mix the automobile exhaust treatment liquid with the cerium-containing raw material for preparation. The cerium-containing raw material is relatively expensive as a catalyst and needs to be fully mixed in the automobile exhaust treatment liquid. At this time, since the cerium-containing raw material cannot be fully dispersed first and then evenly introduced into the interior of the automobile exhaust treatment liquid, the mixing efficiency of the two is low, and a long period of stirring and mixing is required. Moreover, the uniformity of the final mixing cannot be guaranteed, which can easily affect the subsequent exhaust gas purification effect of the automobile exhaust treatment liquid. At the same time, due to the limitations of the equipment's own structure, it is impossible to perform efficient dual-channel continuous automobile exhaust treatment liquid preparation operations and cannot meet daily use needs. Therefore, it is urgent to design a preparation device and preparation method for cerium-containing automobile exhaust treatment liquid to solve the above problems. Summary of the invention

The first liquid guide seat and the second liquid guide seat can be used for switching the inlet and outlet of the automobile exhaust treatment liquid raw materials. Then, other raw materials flow back and forth between the first liquid guide seat and the second liquid guide seat along the central sleeve frame and the tapered tubes and connecting tubes at both ends. When the raw materials enter the tapered tube and the connecting tube from the first liquid guide seat, preliminary flow convergence can be performed to increase the flow rate of the raw materials inside the central sleeve frame. Then, the central sleeve frame expands the raw materials through the tapered tube and the connecting tube. The scattered outflow operation allows the raw materials inside the center sleeve to be operated in a high-speed centralized flow. At this time, the driving motor inside the motor frame on the side of the limit side plate is started, and the center sleeve is driven to rotate as a whole from the ring gear of the center sleeve through the rotation of the driving gear at one end. Then, the center sleeve can rotate stably and at high speed through the rotating inner tube at the center of the internal center tube under the limit of the ring bearings at both ends, thereby cooperating with the center sleeve to rotate and guide on the internal cross feed frame, and the automobile exhaust treatment liquid raw materials passing through the center sleeve are placed in the foaming liner inside the cross feed frame; S2. The four groups of material guide barrels at the upper and lower ends of the first liquid guide seat and the second liquid guide seat can be used to control the flow direction of the raw materials for the production of automobile exhaust treatment liquid.

The inlet and outlet pipes of the automobile exhaust treatment liquid raw materials are respectively connected to the upper and lower connecting valve ports on the side of the material guide barrel, and the raw materials are introduced from the top of the first liquid guide seat. The automobile exhaust treatment liquid, and then the rotating material control seat and the spiral material control sheet, cooperate with the material control inner tube and the material control spiral groove at one end of the material guide barrel to carry out the quantitative operation of the automobile exhaust treatment liquid raw material feeding operation, and then pass through the pipeline structure composed of the central sleeve and the tapered tubes and connecting tubes at both ends to complete the uniform mixing of the cerium-containing, and the interior of the first liquid guide seat and the second liquid guide seat can be controlled by the liquid guide plate, along the adaptive rotation of the torsion shaft, to control the flow operation at the liquid guide groove and the liquid storage port, and efficiently control the up and down circulation operation of the automobile exhaust treatment liquid raw material.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The device and method for preparing the cerium-containing automobile exhaust treatment liquid can enable the device to perform more efficient and uniform preparation of the cerium-containing automobile exhaust treatment liquid by arranging a central sleeve frame, a tapered tube, a connecting tube, a first liquid guide seat, a second liquid guide seat, a central tube, a feed seat, a limit side plate, a motor frame, a drive motor, a drive gear, a ring gear, a pressurized bubble unit, a ring bearing, a rotating inner tube, a cross groove, a feed trough, a feed cone groove, a sealing ring seat, a material-leveling side ring tube, a joint, a material-leveling trough, a feed trough, a cross feed frame, a foaming liner and a foaming hole groove. During the process, the staff first puts the automobile exhaust treatment liquid and other raw materials needed for production into the first liquid guide seat or the second liquid guide seat. The first liquid guide seat and the second liquid guide seat can be used for switching the inlet and outlet of the automobile exhaust treatment liquid raw materials. Then the other raw materials flow back and forth between the first liquid guide seat and the second liquid guide seat along the central sleeve frame and the tapered tubes and connecting tubes at both ends. When the raw materials enter the tapered tube and the connecting tube from the first liquid guide seat, they can be initially concentrated to increase the flow rate of the raw materials inside the central sleeve frame. Then the central sleeve frame passes the raw materials through the tapered tube and the connecting tube. The tube is diffused and flows out, so that the raw materials inside the center sleeve can be concentratedly flowed at a high speed. At this time, the driving motor inside the motor frame on the side of the limit side plate is started, and the center sleeve is driven to rotate as a whole from the ring gear of the center sleeve through the rotation of the driving gear at one end. Then, the center sleeve can rotate stably and at a high speed through the rotating inner tube at the center of the internal center tube under the limit of the ring bearings at both ends, thereby cooperating with the center sleeve to rotate and guide the internal cross feed frame, and the automobile exhaust treatment liquid raw materials passing through the center sleeve are dispersed in the cross feed frame. In the foaming tank, efficient eddy current diversion operation is carried out, and at the same time, the pressurized bubble unit at the bottom of the feed seat is started to guide the cerium-containing production raw materials in the raw material tank, and then divert them from the material-leveling side ring pipe on the side of the central sleeve to the cross feed rack inside the central sleeve, and finally uniformly foam and mix them with the automobile exhaust treatment liquid raw materials with high-speed eddy current flow in the foaming hole groove of the foaming tank, so that the precious cerium-containing production raw materials can be more efficiently and fully mixed with the automobile exhaust treatment liquid, thereby improving the effect of subsequent automobile exhaust reduction and purification, which reflects the practicality of the equipment design.

[0017] The device and method for preparing cerium-containing automobile exhaust treatment liquid further improve the overall use effect of the equipment through the central sleeve frame, tapered pipe, connecting pipe, first liquid guide seat, second liquid guide seat, liquid guide groove, liquid storage port, torsion shaft, liquid guide plate, feed seat, material guide barrel, limit side plate, transmission frame, adjustment motor, transmission belt, extension rod, material control rotating seat, spiral material control sheet, material control inner pipe, material control spiral groove, connecting valve port, limit cover, movable plate, raw material tank, sealing seat and connecting valve.

The regulating motor at one end of the transmission frame is started daily to drive the transmission belt at one end, and then the extension rods at the two ends of the bottom are used to drive the material control rotating seat and the spiral material control sheet to perform spiral rotation operation at the interface between the material guide barrel and the first liquid guide seat and the second liquid guide seat. The inlet and outlet pipes of the automobile exhaust treatment liquid raw materials are respectively connected to the upper and lower connecting valve ports on the side of the material guide barrel, and the automobile exhaust treatment liquid is introduced from the top of the first liquid guide seat into the automobile exhaust treatment liquid. The liquid is then processed, and the rotating material control rotating seat and the spiral material control sheet cooperate with the material control inner tube and the material control spiral groove at one end of the guide barrel to perform the quantitative operation of the automobile exhaust treatment liquid raw material, and then pass through the pipeline structure composed of the central sleeve frame and the tapered tubes and connecting tubes at both ends to complete the uniform mixing of cerium, and the interior of the first liquid guide seat and the second liquid guide seat can control the flow operation at the liquid guide groove and the liquid storage port through the liquid guide plate, along the adaptive rotation of the torsion shaft, and efficiently control the up and down circulation operation of the automobile exhaust treatment liquid raw material, so that two cross-type two-way automobile exhaust treatment liquid raw materials and cerium-containing raw materials are formed inside the equipment, and the preparation work is staggered, which greatly improves the production efficiency of the equipment. At the same time, when the central sleeve frame is rotating as a whole, it can be limited by the limit cover at the center of the limit side plate, and the raw material tank of the feed seat can be docked at the movable plate of the limit cover. The raw material tank inside the feed seat is directly extracted and replaced from the movable plate for daily use, so that the precious cerium-containing raw material is efficiently fed, which reflects the comprehensiveness of the equipment design.
