At present, the domestic chlorination method for preparing titanium dioxide has the problems of low product quality, large waste discharge and the like. Titanium dioxide is a multi-component or less-component coated ultrafine particle material which takes titanium dioxide as a main component, is processed into a particle size of 200 nm-350 nm by a chemical method, and is coated with other inorganic matters and organic matters. The acidic mother liquor used for acidolysis in the production process of preparing titanium dioxide by the chlorination method can be polluted by impurities such as particles generated in the preparation engineering, and becomes acidic waste liquor after the acidolysis process is finished. The waste liquid contains high-concentration hydrochloric acid waste liquid and extremely fine titanium dioxide, colloid and other particles, if the waste liquid is directly discharged without treatment, the environment is seriously polluted, and unnecessary resource waste is caused. In the production process of titanium dioxide by the chlorination method, after three-stage condensation and liquefaction are carried out on crude titanium tetrachloride generated by a chlorination furnace, the residual tail gas contains a large amount of N 2、TiCl4、HCl、CO、CO2 and the like, and a treatment process of washing with water and then alkaline washing is generally adopted in industry, and most TiCl 4, HCl and the like are absorbed in the water washing process, so that byproduct hydrochloric acid is generated. At present, the concentration of byproduct hydrochloric acid with 20-27% is about 0.4t when titanium dioxide is produced every 1t of titanium dioxide. Because the water absorbs the SiCl 4、TiCl4 and a small amount of other metal chlorides in the tail gas during spray water washing, the substances are hydrolyzed when meeting water, so that the byproduct hydrochloric acid contains 0.1-1% of colloid impurities, including silicic acid, orthosilicic acid, tiO2 and the like, which makes the byproduct acid system contain white colloid, is difficult for downstream customers to accept, is difficult for marketing, and affects the normal production of titanium dioxide for a long time.

The side wall of the filter cavity 11 is provided with a first interface 111 and a first valve 121 for opening and closing the first interface 111, which is mainly used for controlling the raw material solution to enter the filter cavity 11; the bottom of the filter cavity 11 is provided with a third interface 113 and a third valve 123 for opening and closing the third interface 113, which is mainly used for discharging waste liquid containing high-concentration impurities during back flushing; the buffer cavity 12 is provided with a second interface 112 and a second valve 122 for opening and closing the second interface 112, and the interface is mainly used for flowing filtered clear liquid out of the buffer cavity 12; the buffer cavity 12 is provided with a fourth interface 114 and a fourth valve 124 for opening and closing the fourth interface 114; the fourth port 114 is connected to a fluid delivery device (not shown) for providing backwash liquid, here backwash liquid, filtered clear liquid (liquid free of impurities) to the buffer chamber 12. In addition, the upper end of the flow guiding pipe 4 extends out of the filter cavity 11 and is coaxially connected with the power equipment 5, and the power equipment is a variable speed motor and is used for driving the flow guiding pipe 4 to rotate so as to drive the filter assembly 2 to rotate together.
Specifically, referring to fig. 2, fig. 2 is a schematic structural diagram of a filtering component in the present embodiment. The filter assembly 2 in this embodiment comprises four sets of filter elements 21 arranged circumferentially along the flow conduit 3, each set of filter elements 21 having 16 cylindrical filter elements, each filter element being arranged radially along the flow conduit.
The normal filtering flow of this embodiment is: the first valve 121, the second valve 122 are opened, the third valve 123, the fourth valve 124 are closed, the fluid enters the filter cavity 11 from the first port 111, then the filter element 21 and the flow guide tube 3 enter the buffer cavity 12, and finally the fluid flows out from the second port 112.

In this embodiment, the filter assembly 2 also includes four sets of filter elements 21, where the four sets of filter elements are disposed along the circumference of the flow guide 3, each set of filter elements 21 has 16 cylindrical filter elements, and each filter element is disposed radially along the flow guide, but the filter elements in two adjacent sets of filter elements are disposed at intervals along the axial direction of the flow guide, i.e. are staggered from each other, so as to be beneficial to disturbance effect on fluid when the filter elements rotate. Thus, the time for rotating the whole filter element can be further shortened, and impurities on the outer wall of the filter element can be removed more quickly.
Example 3
Embodiment 3 is different from embodiment 1 in that the filter assembly is different from embodiment 1, please refer to fig. 4, fig. 4 is a schematic structural diagram of the filter assembly of this embodiment, in this embodiment, the filter element 21 is a disc-shaped filter disc, and the upper side and the lower side of the filter disc are both provided with filter holes.

Example 5
The filter element in example 5 was also a filter disc, but the filter disc was spiral, as shown in fig. 6.
Testing
Impact of rotational speed on cleaning Effect
The device of example 1 was used for testing, the device was used for filtering titanium white by-product waste acid, the feeding rate was 1m 3/h, and back flushing was performed when the pressure difference between the inlet and outlet of the filter assembly reached 0.25MPa after a period of time. The clear liquid after filtration is used as a back flushing medium in back flushing, the flow is 3.6m 3/h, the flushing time is 2min, and the working period of the motor in the back flushing process is 1min (forward rotation 15s, pause 15s, reverse rotation 15s and pause 15 s). After washing, the clear liquid after filtration is used as a medium for filtration, the filtration flow rate is (1 m 3/h), the filtration is carried out for 0min, and the pressure difference at the inlet and the outlet of the filter assembly is measured after 30 min. The above steps were repeated using the motor rotation speed as a variable, and the influence of the unnecessary rotation speed on the cleaning effect was determined, and the results are shown in table 1.
TABLE 1 differential pressure statistics for example 1 backwashed filter assemblies at different rotational speeds
As can be seen from Table 1, during the secondary filtration, the differential pressure of test cases 1-1 and 1-2 is the same at the initial time and is larger than that of test cases 1-3 and 1-4, which means that impurities still exist in the filter holes after the back flushing in test cases 1-1 and 1-2, and impurities in the filter holes are further cleaned after the rotation speed of test cases 1-3 and 1-4 is increased, because the rotation results in uneven distribution of flow in the filter holes, part of the filter holes are cleaned more quantitatively, and impurities which cannot be flushed out under the condition of partial low impact flow are cleaned, which means that the cleaning effect of the filter assembly can be improved from the rotation speed.
In comparison with the above test cases, the pressure difference at 0min and 30min was significantly increased in test case 1-1, and less in test cases 1-2 and 1-3, and no increase in 1-4. As the secondary filtration adopts the filtered clear liquid as the filter medium, no solid particles which can be intercepted exist in the raw materials, so that no solid impurities which can be intercepted exist on the outer wall of the filter element, the obvious increase of the test example 1 shows that more filter impurities which can be intercepted are adsorbed on the outer wall of the filter element, and the impurities are sucked into the filter holes again in the later stage, so that the filtration period is shortened. This also illustrates that rotating the filter assembly advantageously increases the effectiveness of the backwash.
(II) Effect of Filter Assembly arrangement on cleaning Effect
The devices in the embodiment 1 and the embodiment 2 are adopted for experiments, the sizes and the number of filter holes (the filter areas are the same) of the filter components in the two devices are the same, the titanium dioxide byproduct waste acid is filtered by the devices, the feeding rate is 1m 3/h, and the titanium dioxide byproduct waste acid is backwashed after a period of time when the pressure difference between the inlet and the outlet of the filter components reaches 0.25 MPa. During back flushing, the filtered clear liquid is used as a back flushing medium, the flow is 3.6m 3/h, and different flushing times are selected. After washing, the clear liquid after filtration is used as a medium for filtration, the filtration flow rate is (1 m 3/h), the filtration is carried out for 0min, and the pressure difference at the inlet and the outlet of the filter assembly is measured after 30min. The above steps were repeated using the motor rotation speed as a variable, and the influence of the unnecessary rotation speed on the cleaning effect was determined, and the results are shown in table 2.
Table 2 statistics of differential pressure after different flushing times of filter assemblies
As can be seen from Table 2, when the back flushing time is 1min, the initial pressure difference of the secondary filtration in the embodiment 1 and the embodiment 2 is the same, which indicates that the arrangement mode has no obvious influence on the removal of impurities in the filter holes; comparing test example 2-1 with test example 2-3 and test example 2-2 with test example 2-4, it was found that the difference between the pressure difference after 30min of secondary filtration of test examples 2-3, 2-4 and the initial pressure difference was unchanged, which indicated that the impurities of the filter element were completely cleaned, while the slight increase in test examples 2-1, 2-2 indicated that the impurities of the filter element which could be intercepted still remained, which indicated that the arrangement of example 2 was more advantageous for causing fluid turbulence to remove the impurities of the filter element outer wall.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions easily contemplated by those skilled in the art within the technical scope of the present invention disclosed in the embodiments of the present invention should be covered by the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
