Description

Technical Field

[0001] The invention relates to a new energy material production equipment, in particular to a lithium battery material reaction tail gas filtering and processing device. Background Art

[0002] When the negative electrode materials of lithium batteries react in a high-temperature reactor, a large amount of combustible gas will be produced, and a large amount of dust will be contained. The combustible tail gas mixed with these dusts will be directly discharged into the atmosphere, which will pollute the environment and affect human health. Therefore, these tail gases need to be treated before being discharged. There are several ways to remove dust from tail gas: the conventional way is to use a filter element to filter, but this method requires frequent replacement of the filter element, high production cost, and requires shutdown operation, which reduces production efficiency; the other is through spraying or precipitation, but the effect is not ideal, it needs to be repeated many times, and the efficiency is very low; the third is to use electrostatic plus water flow flushing. For example, by flowing the tail gas into the electric field formed between the electrode tube and the electrode rod, the dust can be ionized to adhere to the inside of the electrode tube, and then the dust can be washed away by the water curtain flowing down from the top of the electrode tube to achieve the effect of dust removal. This method has good dust removal effect and high efficiency, and is most worth adopting. However, since the exhaust gas contains combustible gases, an arc is easily generated between the tip of the upper edge of the electrode tube and the electrode rod in the high-voltage electric field, which can easily ignite the combustible gases inside the device and cause an explosion, resulting in very low safety. Summary of the invention

[0003] The purpose of the present invention is to provide a lithium battery material reaction tail gas filtering and processing device with good filtering effect, stable operation, safety and reliability.

[0004] In order to achieve the above-mentioned purpose, the lithium battery material reaction tail gas filtration treatment device provided by the present invention includes a water tank, a bracket, a conductive tube, a conductive rod, a water supply device, an insulating water supply nozzle and a voltage device. The water tank has an upper cavity and a lower cavity arranged in an upper and lower manner and isolated from each other, the top of the upper cavity is provided with an air inlet, one side of the lower cavity is provided with an air outlet, and the bottom of the lower cavity is provided with a drain outlet; the conductive tube is vertically arranged in the water tank and the upper end opening is located in the upper cavity, and the lower end opening of the conductive tube is located in the lower cavity; the bracket is arranged in the upper cavity and is located above the conductive tube; one end of the conductive rod is arranged in the bracket and is arranged one-to-one with the conductive tube, and the conductive rod The other end of the conductive rod coaxially extends into the conductive tube and extends to the lower end of the conductive tube; the conductive rod and the electrode tube are arranged with a gap; the two electrodes of the voltage device are respectively connected to the conductive tube and the conductive rod to form a high-voltage electric field between the latter two; the cross-section of the conductive tube is square; the water supply device is connected to the insulating water supply nozzle; the insulating water supply nozzle is arranged on the bracket and the water outlets are respectively located at the upper end of the conductive tube and close to each inner side wall of the conductive tube; the insulating water supply nozzle is located between the inner side wall of the conductive tube and the conductive rod; the width of the water outlet of the insulating water supply nozzle is equal to the width of one inner side wall of the conductive tube, so that water flows through each inner side wall of the conductive tube to form a water curtain.

The insulating water supply nozzle 5 is arranged on the bracket 2 and the water outlet is respectively located at the upper end of the conductive tube 3 and close to each inner side wall of the conductive tube 3. That is, the four inner side walls of the square conductive tube 3 are respectively provided with an insulating water supply nozzle 5. The insulating water supply nozzle 5 is located between the inner wall of the conductive tube 3 and the conductive rod 4; the width of the water outlet of the insulating water supply nozzle 5 is equal to the width of the inner wall of the conductive tube 3, so that water flows through the inner walls of the conductive tube 3 to form a water curtain that completely covers the inner walls; the water curtain flows downward along the conductive tube 3 to the lower cavity 1b under the action of gravity.

[0021] See also Figure 3The insulating water supply nozzle 5 includes an inlet section 51, a bending section 52 and an outlet section 53.

[0025] Based on the above and in combination with the above drawings, the working principle of the present invention is described in detail below:

[0026] During operation, first, the water supply device supplies water to the insulating water supply nozzle 5, and the insulating water supply nozzle 5 supplies water to the inner wall of the conductive tube 3, and each inner wall of the conductive tube 3 forms a water curtain. After that, the voltage device applies a high voltage between the conductive tube 3 and the conductive rod 4, so that a high-voltage electrostatic field is formed between the conductive tube 3 and the conductive rod 4. Then, the exhaust gas enters the upper cavity 1a through the air inlet 1c, and then the exhaust gas enters the upper end openings of each conductive tube 3 from the upper cavity 1a. When the exhaust gas passes through the inside of the conductive tube 3, the exhaust gas with dust is ionized, so that the dust is charged, and then the charged dust approaches the inner wall of the conductive tube 3 under the action of the electric field. At this time, the charged dust follows the water flow under the flushing of the water curtain and flows downward into the lower cavity 1b. After that, the dust enters the filter box 6 from the drain port 1e with the water flow. The exhaust gas after ionization and dust removal is discharged from the outlet 1d and flows into another device for purifying exhaust gas. When the water in the filter box 6 reaches the highest water level, the water level detector 76 controls the water pump 71 to start and controls the first switch control valve 72 to open, so as to extract the water from the filter box 6 and re-transport it to the insulated water supply nozzle 5 for recycling. After a period of use, the first switch control valve 72 can be controlled to close, and the second switch control valve 73 can be opened to directly discharge the water from the filter box 6. When the dust in the filter box 6 accumulates to a certain extent, the filter box 6 needs to be cleaned in time.

[0027] Compared with the prior art, the present invention sets the conductive tube 3 into a square tube structure, and sets an insulating water supply nozzle 5 on the bracket 2, so that the insulating water supply nozzle 5 is close to each inner wall of the conductive tube 3, and the width of the water outlet of the insulating water supply nozzle 5 is equal to the width of an inner wall of the conductive tube 3, so that each inner wall of the conductive tube 3 can produce a water curtain with the same width as the inner wall, so that the water curtain can completely cover the surface of each inner wall of the conductive tube 3, so that the inner wall of the conductive tube 3 can be flushed with dust in an all-round and timely manner to improve the filtering effect; and the inner wall of the conductive tube 3 can be covered in all directions to avoid partial exposure of the conductive tube 3 near the conductive rod 4, thereby preventing the generation of arcs and improving the safety of use. In addition, since the upper opening of the conductive tube 3 has a convex edge, the edge can easily generate an arc with the conductive rod 4. Therefore, by arranging the insulating water supply nozzle 5 between the inner wall of the conductive tube 3 and the conductive rod 4, the insulating water supply nozzle 5 can effectively isolate the edge of the upper opening of the conductive tube 3 from the conductive rod 4, thereby effectively preventing the latter from generating an arc. Therefore, the risk of arc detonating exhaust gas is greatly reduced, the safety of use is further improved, and the entire filtering treatment device is very stable, safe and reliable in operation.

[0028] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention still fall within the scope covered by the present invention.
