Description

[0001] The present invention relates to the field of soot purification and treatment equipment, and particularly to a soot purification and treatment equipment for zinc oxide production. Background Art

[0002] In the working workshop and storage workshop of a zinc oxide production factory, there are large amounts of soot-filled air pollution phenomena. In the workshop, a ceiling-mounted spraying mechanism is usually used to spray and settle the soot in the air. This treatment method can effectively improve the soot content in the air, but the downwardly sprayed liquid will also make the workshop more humid, resulting in the zinc oxide products placed in the workshop being prone to deterioration when encountering water. If the method of placing a batch of soot purification devices on the ground is used to replace the ceiling-mounted spraying mechanism to clean the soot, it will occupy a large area of space in the workshop for placing this batch of soot purification devices, resulting in the waste of a large area of placement space and passage space in the workshop. Chinese Patent No. CN111467887A discloses an underground dust removal system that sucks soot at ground height through an underground liftable suction device, which can solve the problems of the above-mentioned zinc oxide products deteriorating when encountering water and the placement of soot purification devices occupying a large area of space in the workshop. However, after the soot is sucked and collected into the waste collection chamber by this system, there are still a large amount of soot escaping outward to pollute the environment during the loading and unloading process of the soot collected in the waste collection chamber. Summary of the Invention

[0003] In order to overcome the drawback that there is a large amount of soot escaping outward to pollute the environment during the loading and unloading process of soot after using an underground liftable suction device to collect soot in zinc oxide production, the present invention provides a soot purification and treatment equipment for zinc oxide production.

DETAILED DESCRIPTION OF THE INVENTION

[0028] To make the objectives, technical solutions, 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 declared that the orientation terms such as up, down, left, right, front, back, inside, and outside that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and they do not specifically limit the present invention.

[0029] Example 1

[0030] A fume purification and treatment device for zinc oxide production, as Figures 1-8 shown, includes a buried housing 1, a lifting partition 2, a photosensitive sensor 22, a delivery pipe 3, an infusion pipe 31, a first hose 32, a spray head 33, a waste discharge pipe 4, a collection box 41, a second hose 42, and a gas-liquid mixing suction pump 43; a lifting partition 2 is slidably connected inside the buried housing 1, and the lower sides of the buried housing 1 and the lifting partition 2 are both buried below the ground; several photosensitive sensors 22 are installed on the lifting partition 2; a plurality of ventilation holes 201 structures are respectively formed in the front upper side and the rear upper side of the lifting partition 2; a plurality of ventilation vertical grooves 202 structures communicating with the ventilation hole 201 structures are respectively formed in the front side and the rear side of the lifting partition 2, and the ventilation vertical groove 202 structure is located below the ventilation hole 201 structure; two electric push rods 21 are installed inside the buried housing 1; the telescopic ends of the two electric push rods 21 are commonly fixed to the lifting partition 2; a delivery pipe 3 and a waste discharge pipe 4 are successively fixed inside the buried housing 1; an infusion pipe 31 is fixed inside the lifting partition 2; two first hoses 32 are commonly connected between the infusion pipe 31 and the delivery pipe 3; a plurality of spray heads 33 are connected to the infusion pipe 31; the delivery pipe 3 is externally connected to a spray liquid circulating delivery device; a collection box 41 is fixed inside the lifting partition 2, and the collection box 41 is located below the infusion pipe 31; a plurality of second hoses 42 are commonly connected between the collection box 41 and the waste discharge pipe 4; a gas-liquid mixing suction pump 43 is installed inside the buried housing 1; the inlet end of the gas-liquid mixing suction pump 43 is connected to the waste discharge 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 externally connected filtering device is connected to the water inlet of the externally connected spray liquid circulating delivery device.

[0031] As Figure 3 shown, a sealing ring 11 is installed on the buried housing 1; the sealing ring 11 wraps around the outer surface of the lifting partition 2, and the sealing ring 11 is initially located between the ventilation hole 201 and the ventilation vertical groove 202 of the lifting partition 2.

[0032] As Figure 3 and Figure 6 shown, an electric control valve 34 for controlling the spray flow rate is installed on each spray head 33; several dust sensors 23 are installed on the lifting partition 2.

[0033] The conventional soot purification treatment working steps of a soot purification treatment device for zinc oxide production according to the present invention are as follows.

[0034] The lower sides of the buried housing 1 and the lifting partition 2 are initially buried below the ground, and only the ventilation hole 201 structure area of the lifting partition 2 is above the ground. The upper surface of the lifting partition 2 is a trapezoidal structure that arches upward. 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 the handling vehicles and pedestrians in the workshop to pass. At the same time, the gas-liquid mixing suction pump 43 operates at a low power state to perform suction work in the lifting partition 2 through the waste discharge pipe 4 and the second hose 42, enabling the soot in the external gas to pass through the ventilation hole 201 structure of the lifting partition 2 and enter the interior of the lifting partition 2. Meanwhile, the externally connected spray liquid circulation and conveying device conveys the spray liquid to the liquid delivery pipe 31 through the delivery pipe 3. Under the flow control of the electric control valve 34, the spray head 33 initially sprays the spray liquid downward at a low flow rate. The spray liquid performs a spray treatment on the soot sucked into the lifting partition 2, and the soot and the spray liquid together form wastewater mixed with powder substances, enabling the gas sucked into the lifting partition 2 to complete the soot 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 substances are pumped outward in the direction of the externally connected filtering device along the collection frame 41, the second hose 42, and the waste discharge pipe 4. After the filtering device filters the wastewater mixed with powder substances into clean spray liquid, the spray liquid flows back to the externally connected spray liquid circulation and conveying device for cyclic spraying work, and the purified gas entering the filtering device is directly discharged outward.

[0035] The large-range soot purification treatment working steps of a soot purification treatment device for zinc oxide production according to the present invention are as follows.

[0036] In the conventional soot purification process, if the soot concentration in the workshop suddenly increases, the soot concentration sucked into the lifting partition 2 also increases. At this time, the spraying liquid sprayed downward in the low-flow state cannot completely spray and treat the soot. Therefore, when the high-concentration soot flows through the soot sensor 23, the soot sensor 23 will be triggered. The soot sensor 23 immediately sends a signal to switch to high-power operation to the gas-liquid mixing suction pump 43 through the circuit system, increasing the suction power for the soot. At the same time, the soot sensor 23 also immediately sends a start signal to the electric push rod 21 through the circuit system. The electric push rod 21 pushes the lifting partition 2 to rise, so that the ventilation vertical groove 202 of the lifting partition 2 rises upward to leave the sealing ring 11 and expose above the ground, and a large-scale suction work is carried out on the soot in the workshop. The soot in the workshop is timely sucked into the lifting partition 2. At the same time, the soot sensor 23 immediately sends a signal to switch to high-flow control to the electric control valve 34 aligned in the up and down direction through the circuit system, so that the spray heads 33 in the area corresponding to the high-concentration soot spray the spraying liquid downward in the high-flow state, so that the high-concentration soot can be timely sprayed and treated, and the air in the area with high-concentration soot can be purified in time without wasting the spraying liquid.

[0037] During the process of the electric push rod 21 pushing the lifting partition 2 to rise, when the photosensitive sensor 22 on the lifting partition 2 is blocked by passing or staying handling vehicles and pedestrians, the electric push rod 21 will not push the lifting partition 2 to rise. Only when the passing or staying handling vehicles and pedestrians leave above the lifting partition 2 and do not block the photosensitive sensor 22, the electric push rod 21 will resume pushing the lifting partition 2 to rise, so as to avoid the rising lifting partition 2 from pushing up the passing or staying handling vehicles and pedestrians and causing damage.

[0038] Embodiment 2

[0039] On the basis of Embodiment 1, as Figures 1-8 shown, a number of air guide cylinders 51 are installed on the collection box 41 of this embodiment; a suction fan 52 is installed in each air guide cylinder 51; the lower end of each air guide cylinder 51 is provided with a funnel-shaped structure that contracts downward toward the adjacent second hose 42; the air inlet of the air guide cylinder 51 is connected to two suction hoppers 53 in the front and back; a number of suction holes 530 are formed in both suction hoppers 53; the suction hole 530 structures of the two suction hoppers 53 are respectively aligned with the ventilation holes 201 on the front and back sides of the lifting partition 2.

[0040] In the conventional soot purification process, the gas-liquid mixing suction pump 43 does not need to perform suction work. Only the exhaust fans 52 in each air guide cylinder 51 jointly perform downward suction work. All the exhaust fans 52 pass through the air suction holes 530 of the air suction hopper 53 and closely adhere to the air vent holes 201 of each area of the lifting partition plate 2 to synchronously perform soot suction work. This can not only make the air vent holes 201 of each area of the lifting partition plate 2 have uniform soot suction force, improving the soot suction effect on different areas. During this process, since the working power of the exhaust fan 52 is much smaller than that of the gas-liquid mixing suction pump 43, it can also greatly reduce the soot suction energy consumption in the conventional soot purification process and reduce the cost of the soot purification process.

[0041] Embodiment 3

[0042] On the basis of Embodiment 1, as Figures 1-11 shown, an air delivery pipe 61 is connected to the discharge pipe 431 of the gas-liquid mixing suction pump 43 of this embodiment; a shunt pipe 62 is connected to the air delivery pipe 61. The shunt pipe 62 is provided with six outlet ends; each of the six outlet ends of the shunt pipe 62 is connected to a buried exhaust box 63. The buried exhaust box 63 is installed on the ground. The air delivery pipe 61 and the shunt pipe 62 are both buried below the ground; a number of air outlet holes 630 are provided in each of the six buried exhaust boxes 63; the air outlet holes 630 of the six buried exhaust boxes 63 all face the lifting partition plate 2.

[0043] During the process of the gas-liquid mixing suction pump 43 continuously delivering the purified gas and the wastewater mixed with powder to the external filtering equipment, when the purified gas and the wastewater mixed with powder flow through the discharge pipe 431, the wastewater mixed with powder will directly flow to the external filtering equipment for filtering and purification. Since the purified gas will encounter a relatively large flow resistance when flowing towards the filtering equipment, the purified gas will preferentially flow along the air delivery pipe 61 through the shunt pipe 62 and then be discharged from the air outlet holes 630 of each buried exhaust box 63 towards the lifting partition plate 2. This enables the purified gas to blow the soot settled in the area of the ground far from the lifting partition plate 2 towards the air vent holes 201 of the lifting partition plate 2 during the process of flowing along the ground towards the lifting partition plate 2, improving the soot suction effect of the lifting partition plate 2 on the soot settled at a long distance on the ground.

[0044] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
