Description

Technical Field

[0001] The invention relates to the field of smoke purification equipment, in particular to smoke purification equipment for zinc oxide production. Background Art

[0002] In the workshop and storage workshop of the zinc oxide production plant, there is a lot of smoke and dust in the air. The workshop usually uses a ceiling-mounted spray mechanism to spray and settle the smoke and dust in the air. This treatment method can effectively improve the smoke and dust content in the air, but the liquid sprayed downward will also make the workshop more humid, causing the zinc oxide products placed in the workshop to easily deteriorate when exposed to water. If the method of placing smoke and dust purification devices in batches on the ground is used to replace the ceiling-mounted spray mechanism to clean the smoke and dust, a large area of ​​​​the workshop will be occupied for placing the smoke and dust purification devices. The batch of smoke purification devices leads to the waste of a large area of ​​placement space and passage space in the workshop. The Chinese patent with publication number CN111467887A discloses an underground dust removal system, which uses an underground liftable suction device to suck the smoke at ground level, which can solve the problem of zinc oxide product deterioration when exposed to water and the problem of the placement of smoke purification devices occupying a large area of ​​space in the workshop. However, after the system collects and absorbs the smoke into a waste collection room, during the loading and unloading process of the smoke collected in the waste collection room, a large amount of smoke still escapes to the outside and pollutes the environment.

DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that the directional terms such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and are not specific limitations of the present invention.

[0018] Example 1 A smoke purification and treatment equipment for zinc oxide production, such as Figure 1-Figure 8 As shown, it includes an underground shell 1, a lifting baffle 2, a photosensitive sensor 22, a delivery pipe 3, a liquid infusion pipe 31, a first hose 32, a spray head 33, a waste pipe 4, a collection frame 41, a second hose 42 and a gas-liquid mixing suction pump 43; the lifting baffle 2 is slidably connected to the buried shell 1, and the lower sides of the buried shell 1 and the lifting baffle 2 are buried below the ground; a number of photosensitive sensors 22 are installed on the lifting baffle 2; a number of vent holes 201 structures are respectively opened on the front upper side and the rear upper side of the lifting baffle 2; a number of ventilation vertical grooves 202 structures connected to the ventilation hole 201 structures are respectively opened on the front side and the rear side of the lifting baffle 2, and the ventilation vertical grooves 202 structures are located below the ventilation hole 201 structures; two electric push rods 21 are installed in the buried shell 1; the telescopic ends of the two electric push rods 21 are fixedly connected together A lifting partition 2; a delivery pipe 3 and a waste pipe 4 are fixedly connected in sequence in the buried shell 1; a liquid infusion pipe 31 is fixedly connected in the lifting partition 2; two first hoses 32 are commonly connected between the liquid infusion pipe 31 and the delivery pipe 3; a plurality of spray heads 33 are connected to the liquid infusion pipe 31; the delivery pipe 3 is externally connected to a spray liquid circulation and delivery device; a collecting frame 41 is fixedly connected in the lifting partition 2, and the collecting frame 41 is located below the liquid infusion pipe 31; a plurality of second hoses 42 are commonly connected between the collecting frame 41 and the waste pipe 4; a gas-liquid mixing suction pump 43 is installed in the buried shell 1; the inlet end of the gas-liquid mixing suction pump 43 is connected to the waste pipe 4; the outlet end of the gas-liquid mixing suction pump 43 is connected to a discharge pipe 431; the discharge pipe 431 is externally connected to a filtering device; the drain outlet of the external filtering device is connected to the water inlet of the external spray liquid circulation and delivery device.

[0019] like Figure 3 As shown, a sealing ring 11 is installed on the buried shell 1; the sealing ring 11 is wrapped around the outer surface of the lifting partition 2, and the sealing ring 11 is initially located between the vent hole 201 and the ventilation vertical groove 202 of the lifting partition 2.

[0020] like Figure 3 and Figure 6 As shown, each spray head 33 is equipped with an electric control valve 34 for controlling the spray flow rate; and a plurality of smoke sensors 23 are installed on the lifting partition 2.

[0021] The conventional fume purification process of the fume purification equipment for zinc oxide production of the present invention is as follows.

[0022] The lower sides of the buried shell 1 and the lifting partition 2 are initially buried below the ground, and only the vent hole 201 structure area of ​​the lifting partition 2 is above the ground, while the upper surface of the lifting partition 2 is an upwardly arched trapezoidal structure. This concealed buried design not only does not occupy the placement space and passage space in the workshop, but the trapezoidal structure on the upper surface of the lifting partition 2 can also be used as a ground speed bump for transport vehicles and pedestrians in the workshop to pass. At the same time, the gas-liquid mixing suction pump 43 operates in a low-power state through the exhaust pipe 4 and the second hose 42 in the lifting partition 2 to perform suction work, so that the smoke and dust in the external gas can pass through the vent hole 201 structure of the lifting partition 2 and enter the interior of the lifting partition 2. At the same time, the external spray liquid circulation conveying equipment conveys the spray liquid to the infusion pipe 31 through the conveying pipe 3. Spray liquid, under the flow control of the electric control valve 34, the spray head 33 initially sprays the spray liquid downward at a low flow state, and the spray liquid sprays the smoke sucked into the lifting partition 2. The smoke and the spray liquid together form wastewater mixed with powder, so that the gas sucked into the lifting partition 2 can complete the smoke purification treatment. At the same time, under the suction of the gas-liquid mixing suction pump 43, the purified gas and the wastewater mixed with powder are pumped toward the external filtering device along the collecting frame 41, the second hose 42 and the waste discharge pipe 4. After the filtering device filters the wastewater mixed with powder into clean spray liquid, the spray liquid flows back to the external spray liquid circulation and conveying equipment for circulating spraying, and the purified gas entering the filtering device is directly discharged to the outside.

[0023] The steps of large-scale smoke purification treatment of smoke purification treatment equipment for zinc oxide production of the present invention are as follows.

[0024] In conventional smoke purification work, if the smoke concentration in the workshop suddenly increases, the smoke concentration sucked into the lifting partition 2 will also increase. At this time, the spray liquid sprayed downward at a low flow rate cannot completely spray and treat the smoke. Therefore, when high-concentration smoke flows through the smoke sensor 23, the smoke sensor 23 will be triggered. The smoke sensor 23 immediately sends a signal to switch to high-power operation to the gas-liquid mixing suction pump 43 through the circuit system to increase the suction power of the smoke. At the same time, the smoke sensor 23 also immediately sends a start signal to the electric push rod 21 through the circuit system, and the electric push rod 21 pushes the lifting partition 2. The partition 2 rises upward, allowing the ventilation vertical groove 202 of the lifting partition 2 to leave the sealing ring 11 upward and be exposed above the ground, so as to perform large-scale suction work on the smoke in the workshop, and promptly suck the smoke in the workshop into the lifting partition 2. At the same time, the smoke sensor 23 immediately sends a signal to switch to high-flow control to the electric control valve 34 aligned in the upward and downward directions through the circuit system, so that the spray head 33 entering the corresponding area with high-concentration smoke can spray the spray liquid downward at a high-flow state, so that the high-concentration smoke can be sprayed in time, and the air in the area with high-concentration smoke can be purified in time without wasting the spray liquid.

[0025] During the process of the electric push rod 21 pushing the lifting partition 2 upward, when the photosensor 22 on the lifting partition 2 is blocked by the passing or stopping transport vehicles and pedestrians, the electric push rod 21 will not push the lifting partition 2 upward. Only when the passing or stopping transport vehicles and pedestrians leave the top of the lifting partition 2 without blocking the photosensor 22, the electric push rod 21 will resume pushing the lifting partition 2 upward, to prevent the rising lifting partition 2 from lifting the passing or stopping transport vehicles and pedestrians upward and causing damage.

[0026] Example 2 On the basis of Example 1, Figure 1-Figure 8 As shown, a plurality of air guide tubes 51 are installed on the collection frame 41 of the present embodiment; an exhaust fan 52 is installed in each air guide tube 51; the lower end of each air guide tube 51 is configured as a bucket-shaped structure that contracts downward toward the adjacent second hose 42; two front and rear exhaust scoops 53 are connected to the air inlet of the air guide tube 51; the two exhaust scoops 53 are each provided with a plurality of exhaust holes 530 structures; the exhaust holes 530 structures of the two exhaust scoops 53 are respectively aligned with the ventilation holes 201 structures on the front and rear sides of the lifting partition 2.

[0027] In conventional smoke purification work, the gas-liquid mixed suction pump 43 does not need to perform suction work, and only the exhaust fans 52 in each air guide tube 51 perform suction work downward together, so that all the exhaust fans 52 can pass through the exhaust hole 530 structure of the exhaust hopper 53, and respectively close to the vent hole 201 structure in each area of ​​the lifting partition 2 to perform smoke suction work synchronously. This can not only make the vent hole 201 structure in each area of ​​the lifting partition 2 have a uniform smoke suction force, but also improve the smoke suction effect in different areas. In this process, since the working power of the exhaust fan 52 is much smaller than the working power of the gas-liquid mixed suction pump 43, it can also greatly reduce the smoke suction energy consumption consumed in conventional smoke purification work and reduce the cost of smoke purification work.

[0028] Example 3 On the basis of Example 1, Figure 1-Figure 11 As shown, the discharge pipe 431 of the gas-liquid mixing suction pump 43 of the present embodiment is connected to the air supply pipe 61; the air supply pipe 61 is connected to the diverter pipe 62, and the diverter pipe 62 is provided with six outlet ends; the six outlet ends of the diverter pipe 62 are respectively connected to an underground exhaust box 63, and the underground exhaust box 63 is installed on the ground, and the air supply pipe 61 and the diverter pipe 62 are both buried under the ground; the six underground exhaust boxes 63 are all provided with a plurality of air outlet holes 630 structures; the air outlet holes 630 structures of the six underground exhaust boxes 63 are all facing the lifting partition 2.

[0029] During the process that the gas-liquid mixing suction pump 43 continuously conveys the purified gas and wastewater mixed with powders to the external filtering equipment, when the purified gas and wastewater mixed with powders flow through the discharge pipe 431, the wastewater mixed with powders will directly flow to the external filtering equipment for filtering and purification. Since the purified gas will encounter greater flow resistance when flowing to the filtering equipment, the purified gas will preferentially choose to flow along the gas transmission pipe 61 through the diversion pipe 62, and then be discharged from the air outlet 630 structure of each buried exhaust box 63 toward the lifting baffle 2. During the period when the purified gas flows along the ground to the lifting baffle 2, the smoke and dust settled on the ground away from the lifting baffle 2 can be blown toward the air vent 201 of the lifting baffle 2, thereby improving the suction effect of the lifting baffle 2 on the smoke and dust settled on the ground at a long distance.

[0030] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
