Description

Technical Field

[0001] The invention relates to the technical field of recovery equipment, and in particular to waste heat recovery carbon dioxide cooling and heating combined supply equipment. Background Art

[0002] Chimneys are one of the oldest and most important anti-pollution devices. Their main function is to remove fire and smoke, exhaust flue gas, and improve combustion conditions. According to the materials, they are generally divided into brick masonry, iron, asbestos, and ceramic. These types are generally used in small places. Alkali plants use chimneys in the alkali production process. Carbon dioxide is one of the components in the air. Carbon dioxide is also one of the gases exhaled by our bodies, and the gas discharged from chimneys also contains carbon dioxide. Carbon capture technology is mainly aimed at high-carbon emission energy and its widely used industries. The so-called carbon sequestration refers to the technology of replacing the direct emission of CO2 into the atmosphere with the capture and safe storage of carbon. At the same time, carbon dioxide can be collected as a gas or liquid. The carbon dioxide gas separated by carbon capture needs to be carbon-sequestered.

[0003] When carbon dioxide is collected by chimney, there is no filtering structure installed inside the collection barrel, so that dust may be contained in the flue gas during collection, the gas collection effect is poor, and it is not convenient to recover the heat in the flue gas later. Summary of the invention

[0020] See also Figure 1-5A waste heat recovery carbon dioxide combined heat and cold supply device, comprising a filter tank 2 and a recovery tank 3 arranged on a base 1, an air inlet pipe 5 arranged on the bottom end of the filter tank 2, an exhaust pipe 6 arranged on the bottom end of the recovery tank 3, and a connecting pipe 4 connecting the top ends of the filter tank 2 and the recovery tank 3. A filter mechanism is arranged in the filter tank 2, and the filter mechanism includes a filter ring 15 arranged horizontally in the middle of a filter channel 17 in the filter tank 2, a filter plate 16 arranged in the inner ring of the filter ring 15, two cleaning discs 12 arranged in the filter channel 17 symmetrically about the filter plate 16, a control component arranged in the filter channel 17 and controlling the end faces of the two cleaning discs 12 to be closely attached to the end face of the filter plate 16, and a cleaning component arranged on the cleaning disc 12 and cleaning the dust on the end face of the filter plate 16.

[0021] like Figure 1-5 As shown, the flue gas is passed into the filter tank 2 through the air inlet pipe 5, so that the dust in the flue gas is filtered through the filter plate 16 arranged in the filter tank 2, and when too much dust is accumulated on the filter plate 16, the two cleaning discs 12 are driven by the control component to fit onto the end surfaces of the two ends of the filter plate 16, and the dust on the end surfaces of the filter plate 16 is cleaned by the cleaning component arranged on the cleaning disc 12, which is convenient for continuous filtering of the flue gas, and the dust in the flue gas can be filtered conveniently, ensuring that the heat in the flue gas can be continuously and normally recycled.

[0022] When the adjacent end faces of the two cleaning discs 12 are attached to the end face of the filter plate 16, cleaning grooves 18 are opened on the adjacent end faces of the two cleaning discs 12. The cleaning assembly includes a rotating disc 19 arranged in the cleaning groove 18 opened in the cleaning disc 12 located below the filter plate 16, a plurality of cleaning brushes 20 evenly arranged on the end face of the rotating disc 19 away from the cleaning groove 18, and a rotating motor arranged on the rotating disc 19.

[0025] like Figure 1-3 As shown, when the end surface of the filter plate 16 is cleaned by the cleaning brush 20, air is simultaneously permeated to the filter plate 16 through the air intake device 7, and after the gas passes through the filter plate 16, the cleaned dust is introduced into the dust collecting device 8 through the hose 11 arranged on the cleaning disk 12, so as to clean the dust on the filter plate 16 and collect the cleaned dust, thereby avoiding the situation that the dust is directly discharged from the filter tank 2 after cleaning.

[0026] The control component includes two lifting blocks 14 rotatably arranged on the side surfaces of the cleaning disk 12, a lifting member that arranges the two lifting blocks 14 on the inner wall of the filter channel 17 at one end away from the filter plate 16, and a rotating member that is arranged on the end surface of the cleaning disk 12 away from the cleaning groove 18 and controls the cleaning disk 12 to rotate around the lifting blocks 14.

[0027] The two sides of the cleaning disc 12 are respectively connected to different lifting blocks 14 through rotating rods. The rotating parts include a driven gear 22 which is sleeved on the rotating rod body and one end face of which is fixedly connected to the side face of the lifting block 14, a control motor which is fixedly arranged on the end face of the cleaning disc 12 away from the cleaning tank 18, and a driving gear 21 which is arranged on the output end of the control motor and meshes with the driven gear 22.

The end of the lifting rod 24 is fixedly connected to the lifting block 14.

[0029] like Figure 1-5As shown, when the dust in the flue gas is filtered through the filter plate 16, the end faces of the two cleaning discs 12 are in a vertical state. When the dust on the end faces of the filter plate 16 needs to be cleaned, the lifting screw 25 is driven by the motor to rotate. At this time, the lifting rod 24 inserted in the lifting slot 23 will move upward, so that it is convenient to drive the cleaning disc 12 to move toward the filter plate 16 through the lifting block 14. In the process of the cleaning disc 12 moving toward the filter plate 16, the driving gear 21 is first driven to rotate by the control motor, so as to facilitate driving the driving gear 21 The meshing driven gears 22 rotate relative to each other, which can drive the cleaning disc 12 to rotate around the lifting block 14 and be arranged horizontally, so that the end face of the cleaning groove 18 is closely fitted on the end face of the filter plate 16, and then the cleaning brush 20 is used to clean the dust on the end face of the filter plate 16, and the air intake device 7 is used to clean the dust filtered on the end face of the filter plate 16 and collect it in the dust collecting device 8, so that the filter plate 16 can continuously filter the flue gas, and the dust in the flue gas can be easily filtered, ensuring that the heat in the flue gas can be continuously and normally recycled.
