[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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.

[0024] Example 1:

[0025] See also Figure 1-5The utility model provides a technical solution: a multi-stage spray dust removal system for high-temperature dust, comprising a primary treatment device 1 and a secondary treatment device 2, wherein the primary treatment device 1 is located on the left side of the secondary treatment device 2, the primary treatment device 1 comprises a first treatment tower 11, the secondary treatment device 2 comprises a second treatment tower 21, a ventilation pipe 3 is arranged between the first treatment tower 11 and the second treatment tower 21, the lower ends of the first treatment tower 11 and the second treatment tower 21 are both provided with a bracket 4, the lower end of the first treatment tower 11 is provided with a collecting component 5, the interior of the first treatment tower 11 is provided with a spray dust removal component 6, and the interior of the second treatment tower 21 is provided with a filtering device 7.

[0026] Specifically, the primary treatment equipment 1 can perform primary cooling and dust removal treatment on the high-temperature dust, and the secondary treatment equipment 2 can purify the waste gas generated by the treated high-temperature dust. The multi-stage treatment method for high-temperature dust can improve the treatment quality.

[0027] like Figure 1 As shown: one end of the ventilation pipe 3 is installed at the upper end of the first treatment tower 11. The ventilation pipe 3 is connected to the upper end of the first treatment tower 11, and then after bending downward, the other end is installed on the outer wall of the second treatment tower 21. This design can connect the first treatment tower 11 and the second treatment tower 21.

[0028] The outer wall of the first treatment tower 11 is provided with a dust inlet pipe 12 , which can introduce high-temperature dust into the first treatment tower 11 .

[0029] like Figure 2 As shown: the collecting assembly 5 includes a cone 51, the lower end face of the cone 51 is provided with a drain pipe 52, the outer wall of the drain pipe 52 is provided with a valve 521, the cone 51 can collect high-temperature dust and debris after spraying treatment, and the debris can be discharged from the drain pipe 52 by opening the valve 521.

[0030] The spray dust removal assembly 6 includes a spray pipe 61 installed in the first treatment tower 11, and a plurality of atomizing spray heads 62 are provided at the lower end of the spray pipe 61. The first treatment tower 11 is provided with a water receiving pipe 13, and the water receiving pipe 13 is connected to the spray pipe 61. After the water receiving pipe 13 is connected to the water source, the water can be output to the spray pipe 61, and then processed into water mist by the atomizing spray head 62. The water mist is in full contact with the high-temperature dust, which reduces the temperature of the high-temperature dust on the one hand and absorbs harmful particles in the high-temperature dust on the other hand.

[0031] The interior of the first treatment tower 11 is provided with a mounting ring 14, and the interior of the mounting ring 14 is provided with a downwardly protruding mesh filter screen 141. The design of the mesh filter screen 141 can play a certain blocking role on high-temperature dust, so that the water mist can more fully contact the high-temperature dust to improve the treatment effect.

[0032] like Figure 3 As shown: the filtering device 7 includes a hollow cylinder 71, a rotating shaft 72 is provided at the central part of the hollow cylinder 71, and a plurality of ring-shaped filter plates 73 are evenly arranged between the outer wall of the rotating shaft 72 and the interior of the hollow cylinder 71. The filter plates 73 in the hollow cylinder 71 can adsorb harmful particulate matter in the exhaust gas generated by high-temperature dust, thereby achieving the function of further treatment.

[0033] The lower end face of the second treatment tower 21 is provided with a motor 22, and the upper end of the output shaft of the motor 22 is fixedly connected to the lower end of the rotating shaft 72. The motor 22 can drive the rotating shaft 72 to rotate, thereby rotating the filter plate 73, so that the filter plate 73 can fully contact with the exhaust gas to adsorb harmful particles in the exhaust gas.

[0034] like Figure 2 As shown, the upper end surface of the second treatment tower 21 is provided with an outlet pipe 23, and the outlet pipe 23 can discharge the treated gas.

[0035] The specific working principle of this embodiment is as follows: during operation, first, high-temperature particles enter the first treatment tower 11 from the dust inlet pipe 12. At this time, after the water supply is connected to the water source in the water pipe 13, the water is discharged into the spray pipe 61 and then atomized into water mist by the atomizing spray head 62. The water mist fully contacts the high-temperature particles to cool them down, and at the same time, it can also absorb large particles of dust and collect them in the cone 51. The high-temperature dust in the first treatment tower 11 will hit the mesh filter 141, slowing down the flow rate.

[0036] The waste gas containing high-temperature particles treated by the first treatment tower 11 will be output from the ventilation pipe 3 to the second treatment tower 21. When the waste gas reaches the second treatment tower 21, the motor 22 is started to drive the rotating shaft 72 to rotate. Synchronously, the empty cylinder 71 and the filter plate 73 rotate. As the empty cylinder 71 and the filter plate 73 rotate, the filter plate 73 will fully contact the waste gas to adsorb harmful substances in the waste gas. The waste gas after adsorption treatment can meet the emission standards and be discharged from the outlet pipe 23.

[0037] It should be noted that the power supply in the above embodiment is a technical means well known to those skilled in the art. A suitable controller can be selected according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the above working principle, in which the electrical components are electrically connected in sequence. The detailed connection means are well known in the art. The above mainly introduces the working principle and process, and no further explanation of the electrical control is given.

[0038] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
