In the utility model, when the scraper structure in the dirt cleaning inner core assembly rotates at a high speed, the spiral airflow generating component installed on the scraper structure can also rotate synchronously at a high speed in the inner cavity of the waste liquid drying body. When the spiral airflow generating component rotates at a high speed, an upward spiral airflow can be generated. The spiral airflow can enable the high-temperature steam to spirally move with the spiral airflow in the waste liquid drying body, and at the same time, the heat is evenly distributed in the waste liquid drying body during the spiral movement.

After the blade of each scraper head is in line contact with the side wall of the inner cavity of the waste liquid drying cylinder, it can scrape off the dirt on the side wall of the inner cavity of the waste liquid drying cylinder in a circular rotation.

[0045] 6. In the present invention, each spiral blade can perform a circular rotation synchronously with the circular rotation of the L-shaped scraper frame.

[0058] Embodiment 1

[0059] like Figure 1-9 As shown, the utility model provides a technical solution:

[0060] A desulfurization waste liquid drying device, comprising:

[0061] A waste liquid recovery machine body assembly 10, wherein the waste liquid recovery machine body assembly 10 contains desulfurization waste liquid to be dried;

[0062] The waste liquid drying body 20 is installed on the waste liquid recovery body assembly 10. The waste liquid drying body 20 includes a waste liquid drying cylinder 201 and a drying cylinder cover 202 installed on the top opening of the waste liquid drying cylinder 201. The waste liquid drying cylinder 201 and the drying cylinder cover 202 are detachably connected;

[0063] A steam gas pipe 80 is installed on the drying cylinder cover 202, and the steam in the steam boiler can be passed into the waste liquid drying body 20 through the steam gas pipe 80. Specifically, one end of the steam gas pipe 80 is connected to the steam boiler in the workshop, and the other end extends into the inner cavity of the waste liquid drying cylinder 201 through the drying cylinder cover 202;

[0064] Furthermore, a pressure relief port 205 is provided on one side of the top of the drying cylinder cover 202, and a pressure relief valve 70 is inserted and installed in the pressure relief port 205, and the pressure relief valve 70 is used to achieve pressure relief in the waste liquid drying body 20;

[0065] Two sets of waste liquid spray structures 40, the two sets of waste liquid spray structures 40 are respectively arranged on both sides of the waste liquid drying body 20, one end of the two sets of waste liquid drying body 20 is respectively installed on both sides of the waste liquid recovery body assembly 10, and the other ends of the two sets of waste liquid spray structures 40 are respectively installed on both sides of the drying cylinder cover 202;

[0066] The two groups of waste liquid spray structures 40 can simultaneously extract the desulfurized waste liquid in the waste liquid recovery body assembly 10 and spray it into the waste liquid drying body 20 in a cross-shaped manner. The cross-sprayed waste liquid can contact the steam from two directions at the same time.

[0067] Motor 50, motor 50 is mounted on the drying cylinder cover 202;

[0068] A dirt cleaning inner core assembly 60, which is rotatably mounted in the inner cavity of the waste liquid drying cylinder 201, and one end of the dirt cleaning inner core assembly 60 is connected to the output shaft of the motor 50;

[0069] The dirt cleaning core assembly 60 is composed of a scraper structure and a spiral airflow generating component installed on the scraper structure.

[0070] In this embodiment, the steam in the steam boiler is continuously injected into the waste liquid drying body 20 through the steam gas pipe 80, so that a high-temperature steam environment is formed in the waste liquid drying body 20. At this time, the two sets of waste liquid spray structures 40 and the motor 50 are started. The two sets of waste liquid spray structures 40 can extract the desulfurized waste liquid in the waste liquid recovery body assembly 10 from two directions at the same time when working, and spray it into the waste liquid drying body 20 in a cross form from two directions. The cross-sprayed waste liquid can contact with the steam from two directions at the same time, thereby increasing the contact surface between the waste liquid and the steam, thereby increasing the drying efficiency of the waste liquid, and improving the drying effect of the waste liquid;

[0071] At the same time, when the motor 50 is started, the motor 50 can drive the dirt cleaning inner core assembly 60 through its output shaft, so that the dirt cleaning inner core assembly 60 can rotate at a high speed in the waste liquid drying body 20. When the dirt cleaning inner core assembly 60 rotates at a high speed in the waste liquid drying body 20, the scraping structure in the dirt cleaning inner core assembly 60 can scrape off the dirt on the bottom and side walls of the inner cavity of the waste liquid drying cylinder 201, thereby preventing the dirt from accumulating more and more in the inner cavity of the waste liquid drying cylinder 201.

[0072] In addition, when the scraper structure in the dirt cleaning core assembly 60 rotates at a high speed, the spiral airflow generating component installed on the scraper structure can also rotate synchronously at a high speed in the inner cavity of the waste liquid drying body 20. When the spiral airflow generating component rotates at a high speed, an upward spiral airflow can be generated. The spiral airflow can enable the high-temperature steam to spirally move with the spiral airflow in the waste liquid drying body 20, and at the same time as the spiral movement, the heat is evenly distributed in the waste liquid drying body 20. The cross-sprayed waste liquid can also spirally move with the spiral airflow. When the waste liquid and steam spirally move, the waste liquid and steam can further meet and contact, thereby further increasing the contact surface and contact time between the waste liquid and the steam, thereby further increasing the drying efficiency of the waste liquid, and further improving the drying effect of the waste liquid.

[0073] Since the waste liquid drying cylinder 201 and the drying cylinder cover 202 in the waste liquid drying body 20 can be easily disassembled, when the drying cylinder cover 202 is disassembled from the waste liquid drying cylinder 201, the waste liquid drying cylinder 201 and the drying cylinder cover 202 can also be easily cleaned.

When the shaft 601 rotates at high speed, it can synchronously drive the rotation of multiple L-shaped scraper racks 602. When the multiple L-shaped scraper racks 602 rotate at high speed, the bottom of each L-shaped scraper rack 602 can slide in a circular form on the bottom of the inner cavity of the waste liquid drying cylinder 201, so that the dirt on the bottom of the inner cavity of the waste liquid drying cylinder 201 can be scraped off. At the same time, each scraper head 6022 can move synchronously with the circular motion of the L-shaped scraper rack 602. After the blade of each scraper head 6022 is in line contact with the inner cavity side wall of the waste liquid drying cylinder 201, it can scrape off the dirt on the inner cavity side wall of the waste liquid drying cylinder 201 in the form of circular rotation.

[0094] Embodiment 5

[0095] like Figure 1-9 As shown, based on the second embodiment, the following improvements are made:

[0096] In order to optimize the installation method, specific structure and operation logic of the two groups of waste liquid spray structures 40, in the present embodiment, further, the waste liquid recovery box 101 is connected with discharge ports 106 on both side walls adjacent to the waste liquid filling pipe 103, and the two discharge ports 106 are arranged opposite to each other.

Since the two atomizing nozzles 404 are distributed in a V shape, the desulfurization waste liquid sprayed from the nozzles of the two atomizing nozzles 404 can be atomized and sprayed in a cross form, thereby increasing the contact area between the waste liquid and the high-temperature steam.

[0104] In summary, the workflow of the utility model is:

[0105] like Figure 1-9 As shown, the steam in the steam boiler is continuously injected into the waste liquid drying body 20 through the steam gas pipe 80, so that a high-temperature steam environment is formed in the waste liquid drying body 20. At this time, the two sets of waste liquid spray structures 40 and the motor 50 are started. The two sets of waste liquid spray structures 40 can extract the desulfurized waste liquid in the waste liquid recovery body assembly 10 from two directions at the same time when working, and spray it into the waste liquid drying body 20 in a cross form from two directions. The cross-sprayed waste liquid can contact with the steam from two directions at the same time, thereby increasing the contact surface between the waste liquid and the steam, thereby increasing the drying efficiency of the waste liquid, and improving the drying effect of the waste liquid;

[0106] At the same time, when the motor 50 is started, the motor 50 can drive the dirt cleaning inner core assembly 60 through its output shaft, so that the dirt cleaning inner core assembly 60 can rotate at a high speed in the waste liquid drying body 20. When the dirt cleaning inner core assembly 60 rotates at a high speed in the waste liquid drying body 20, the scraping structure in the dirt cleaning inner core assembly 60 can scrape off the dirt on the bottom and side walls of the inner cavity of the waste liquid drying cylinder 201, thereby preventing the dirt from accumulating more and more in the inner cavity of the waste liquid drying cylinder 201.

[0107] In addition, when the scraper structure in the dirt cleaning core assembly 60 rotates at a high speed, the spiral airflow generating component installed on the scraper structure can also rotate synchronously at a high speed in the inner cavity of the waste liquid drying body 20. When the spiral airflow generating component rotates at a high speed, an upward spiral airflow can be generated. The spiral airflow can enable the high-temperature steam to spirally move with the spiral airflow in the waste liquid drying body 20, and at the same time as the spiral movement, the heat is evenly distributed in the waste liquid drying body 20. The cross-sprayed waste liquid can also spirally move with the spiral airflow. When the waste liquid and steam spirally move, the waste liquid and steam can further meet and contact, thereby further increasing the contact surface and contact time between the waste liquid and the steam, thereby further increasing the drying efficiency of the waste liquid, and further improving the drying effect of the waste liquid.

[0108] Since the waste liquid drying cylinder 201 and the drying cylinder cover 202 in the waste liquid drying body 20 can be easily disassembled, when the drying cylinder cover 202 is disassembled from the waste liquid drying cylinder 201, the waste liquid drying cylinder 201 and the drying cylinder cover 202 can also be easily cleaned.

[0109] Specifically, when the two suction pumps 401 are started synchronously, the waste liquid in the waste liquid recovery box 101 can be extracted through the corresponding suction pipe 402, and transported to the corresponding atomizing nozzle 404 through the corresponding delivery pipe 403. Since the two atomizing nozzles 404 are distributed in a V shape, the desulfurization waste liquid sprayed from the nozzles of the two atomizing nozzles 404 can be atomized and sprayed in a cross form, thereby increasing the contact area between the waste liquid and the high-temperature steam.

[0110] Specifically, the motor 50 can drive the rotation of the shaft 601 in the scraper structure through its output shaft. When the shaft 601 rotates at high speed, it can synchronously drive the rotation of multiple L-shaped scraper racks 602. When the multiple L-shaped scraper racks 602 rotate at high speed, the bottom of each L-shaped scraper rack 602 can slide in a circular form on the bottom of the inner cavity of the waste liquid drying cylinder 201, so that the dirt on the bottom of the inner cavity of the waste liquid drying cylinder 201 can be scraped off. At the same time, each scraper head 6022 can move synchronously with the circular motion of the L-shaped scraper rack 602. After the blade of each scraper head 6022 is in line contact with the inner cavity side wall of the waste liquid drying cylinder 201, it can scrape off the dirt on the inner cavity side wall of the waste liquid drying cylinder 201 in the form of circular rotation.

[0111] Specifically, each spiral blade 603 can perform a circular rotation synchronously with the circular rotation of the L-shaped scraper frame 602. When the plurality of spiral blades 603 perform a circular rotation at a high speed, an upward spiral airflow can be formed in the waste liquid drying body 20.

[0112] The above different embodiments can be combined, replaced and used in conjunction with each other.
