Description

Technical Field

[0001] The present invention relates to the field of waste gas treatment, in particular to the field of oil mist waste gas treatment, and in particular to an oil mist treatment device for industrial waste gas and a treatment method thereof. Background Art

[0002] Industrial waste gas needs to be purified before it can be discharged. Some industrial waste gas contains oil mist, for example, asphalt fume. In this case, the treatment process needs to include oil mist removal. In the prior art, tar particles and other oil mist components in the smoke are generally captured by electrostatic capture. Specifically, the electrostatic capture method uses an electrostatic field to capture particles and tar components, so that they move to the dust collecting electrode of the electrostatic field. After being captured, they are gathered into a liquid state, flow downward by their own gravity, and are regularly discharged from the bottom of the electrostatic collector. This method has some shortcomings. For example: on the one hand, the dust collecting electrode and the emitting electrode that constitute the electrostatic field are generally arranged in parallel and relative to each other. The flow trajectory of the flue gas in the electrostatic field is equal to the length of the dust collecting electrode. The flow trajectory is relatively short, and the capture and purification effect needs to be improved. On the other hand, as the purification process continues, the dust collecting electrode is covered with oil mist components, and these oil mist components gather and flow relatively slowly. Therefore, it is easy to cause a thick layer of oil mist components on the surface of the dust collecting electrode, which greatly affects the subsequent purification effect and needs to be improved.

[0003] Based on the above, the present invention proposes an oil mist treatment device for industrial waste gas and a treatment method thereof. Summary of the invention

[0004] In order to solve the problems mentioned in the above background, the present invention provides an oil mist treatment device for industrial waste gas and a treatment method thereof.

[0005] In order to achieve the above technical objectives, the technical solution adopted by the present invention is as follows.

[0006] An oil mist treatment device for industrial waste gas comprises an outer shell, an oil mist removal mechanism and an oil scraping mechanism are arranged inside the outer shell, the oil mist removal mechanism comprises an upper rotating rod and a lower rotating rod and a side rotating disk whose axis is parallel to the width direction of the outer shell, a plurality of upper rotating rods are arranged in an array along the length direction of the outer shell, a plurality of lower rotating rods are located below the upper rotating rods, a side rotating disk is arranged between the upper rotating rod and the lower rotating rod, two side rotating disks are arranged between two adjacent upper rotating rods and are respectively located at two ends of the upper rotating rod, and the side rotating disks between the two adjacent upper rotating rods are coaxial;

The plurality of upper rotating rollers and the plurality of side rotating discs cooperate to make the portion of the metal strip located above the lower rotating roller present a continuous curved shape;

[0008] The oil mist removal mechanism also includes an emitter located between two adjacent upper rotating rollers, the upper end of the emitter is connected to the upper cavity wall of the outer shell, and the lower end is close to the bottom of the metal strip that is in a continuously curved shape. The two side surfaces of the metal strip along the width direction are respectively fitted with the two cavity walls of the outer shell along the width direction, and the exhaust gas inlet pipe and the exhaust gas outlet pipe are respectively located at the two ends of the continuous bending area.

[0009] As a further improvement and optimization of the present invention, the metal strip is made of a rolled sheet steel strip.

[0010] As a further improvement and optimization of the present invention, the portion of the metal strip in a continuously bent shape cooperates with the plurality of emitters to form a continuously bent region;

[0011] A motor is arranged on the outer surface of the outer shell, and the input end of the upper rotating rod extends out of the outer shell and is connected to the motor through a power transmission member. When the upper rotating rod is driven to rotate by the motor, thereby driving the metal strip to move, the moving direction of the metal strip in the continuous bending area is opposite to the flow direction of the exhaust gas in the continuous bending area.

[0012] As a further improvement and optimization of the present invention, a pull-down rod parallel to the upper rotating rod is arranged below the continuous bending area, the pull-down rod is tangent to the bottom of the metal strip in the continuous bending area, and the pull-down rod is made of a magnet.

[0013] As a further improvement and optimization of the present invention, a contact assembly is arranged under each upper rotating roller, and the contact assembly includes an inner pipe parallel to the upper rotating roller and a plurality of fins arranged in an array on the outer surface of the inner pipe, the ends of the fins are close to the metal strip, and the inlet ends of the inner pipes of the plurality of contact assemblies extend out of the outer shell and are connected through the cold air inlet pipe. A cold air outlet pipe is also arranged on the outer surface of the outer shell, and a sleeve is arranged on the outer side of the exhaust gas inlet pipe, which is connected to the cold air outlet pipe, and an exhaust nozzle is extended from the outer circular surface of the sleeve.

[0014] As a further improvement and optimization of the present invention, the oil scraping mechanism is located below the metal strip, and the oil scraping mechanism includes a longitudinal oil scraping component and a transverse oil scraping component.

[0015] As a further improvement and optimization of the present invention, the longitudinal oil scraper component includes a longitudinal scraper that is in contact with the outer surface of the metal strip. The blade of the longitudinal scraper consists of two oblique blades. The distance between the two oblique blades increases along the moving direction of the metal strip. A heating element is arranged inside the longitudinal scraper.

[0016] As a further improvement and optimization of the present invention, the transverse oil scraping component includes a liquid storage box, in which oil removal medium is stored, an ultrasonic atomization element is arranged in the liquid storage box, and an oil scraping component is arranged at the box opening of the liquid storage box. The oil scraping component includes a synchronous belt whose moving direction is parallel to the width direction of the metal strip, and a plurality of scrapers are arranged in an array along the extension direction on the outer surface of the synchronous belt. The scrapers are made of rubber material and can contact the metal strip.

[0017] As a further improvement and optimization of the present invention, a blower is arranged in front of the transverse oil scraping member along the moving direction of the metal strip.

[0018] A treatment method for industrial waste gas using oil mist treatment equipment:

[0019] Step 1: The exhaust gas enters the continuous bending area through the exhaust gas inlet pipe. In the continuous bending area, the oil mist component in the exhaust gas is stained on the outer surface of the metal strip by the action of the electrostatic field. The exhaust gas after the oil mist component is removed is discharged through the exhaust gas outlet pipe;

[0020] Step 2: The motor drives the upper rotating roller to rotate, thereby driving the metal strip to move. The moving direction of the metal strip that constitutes the continuous bending area is opposite to the flow direction of the exhaust gas in the continuous bending area. During the movement of the metal strip, the oil scraping mechanism is used to scrape the outer surface of the metal strip.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] In this scheme, on the one hand, the electrostatic field in a continuously bent shape can increase the flow trajectory of the exhaust gas and improve the oil mist treatment effect on the exhaust gas. On the other hand, as the exhaust gas continues to flow, the oil mist component in the exhaust gas is continuously affected by the electrostatic field and is adhered to the outer surface of the metal strip, that is, as the exhaust gas flows in the direction of the exhaust gas, the exhaust gas becomes cleaner and the oil mist component adhered to the outer surface of the metal strip becomes less. Since the cleaner the outer surface of the metal strip is, the better the purification effect is, this method can greatly increase the oil mist purification effect of the exhaust gas. Furthermore, as the metal strip continues to move, the metal strip will be subjected to the oil scraping treatment of the oil scraping mechanism when it moves to the position of the lower rotating roller, and will return after being scraped clean, continuing to form an electrostatic field in a continuously bent shape, and the metal strip in the continuously bent electrostatic field still maintains a mode in which the closer it is to the exhaust gas outlet pipe, the cleaner the outer surface is, and the better the purification effect is.

DETAILED DESCRIPTION

[0033] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0034] Reference Figure 1-Figure 8 An oil mist treatment device for industrial waste gas includes an outer shell 100. An oil mist removal mechanism 200 and an oil scraping mechanism 300 are arranged inside the outer shell 100. The former uses an electrostatic field to remove oil mist from industrial waste gas, and the latter is used to scrape oil from the former, so that the oil mist removal performance of the former is maintained at the best. The outer shell 100 is respectively provided with an exhaust gas inlet pipe 101 and an exhaust gas outlet pipe 102 on two sides along the length direction for the exhaust gas to enter and exit.

[0035] Oil mist removal mechanism 200:

[0036] Reference Figure 2-Figure 6The oil mist removal mechanism 200 includes an upper rotating rod 201 and a lower rotating rod 202, and a side rotating disk 203, whose axis lines are parallel to the width direction of the outer shell 100, wherein a plurality of upper rotating rods 201 are arranged in an array along the length direction of the outer shell 100, and a plurality of lower rotating rods 202 are located below the upper rotating rod 202 and are provided with a guide transition function, and a side rotating disk 203 is arranged between the upper rotating rod 201 and the lower rotating rod 202, and two side rotating disks 203 are arranged between two adjacent upper rotating rods 201 and are respectively located at the two ends of the upper rotating rod 201, and the two side rotating disks 203 are coaxial.

[0037] The oil mist removal mechanism 200 also includes a metal strip 204, which has elastic properties. For example, it is made of a tightly rolled sheet steel strip, can be bent and has conductivity and magnetism. The head end of the metal strip 204 passes around the upper rotating rod 201, the side rotating disk 203 and the lower rotating rod 201, and is connected to the tail end of the metal strip 204 to form a closed loop. Multiple upper rotating rods 201 and multiple side rotating disks 203 cooperate to make the part of the metal strip 204 located above the lower rotating rod 202 present a continuous curved shape.

[0038] The oil mist removal mechanism 200 further includes an emitter 205 located between two adjacent upper rotating rollers 201, and a plurality of emitters 205 are provided correspondingly. The upper end of the emitter 205 is connected to the upper cavity wall of the outer shell 100, and the lower end of the emitter 205 is close to the bottom of the portion of the metal strip 204 in a continuously curved shape. In addition, the two side surfaces of the metal strip 204 along the width direction are respectively attached to the two cavity walls of the outer shell 100 along the width direction. Therefore, the portion of the metal strip 204 in a continuously curved shape is attached to the plurality of emitters 205. 05 cooperates to form a continuous bending area. The metal strip 204 serves as a dust collecting electrode and cooperates with the emitter 205 to form an electrostatic field in the continuous bending area. The exhaust gas inlet pipe 101 and the exhaust gas outlet pipe 102 are respectively located at the two ends of the continuous bending area. A blower can be set at the exhaust gas inlet pipe 101, or an induced draft fan can be set at the exhaust gas outlet pipe 102. Therefore, the exhaust gas will flow in the continuous bending area in turn, and will not be discharged until the electrostatic field has removed the oil mist for a sufficient period of time, and the oil mist removal effect is better.

[0039] Preferred embodiment, refer to Figure 2The outer surface of the outer shell 100 is provided with a motor 107, and the input end of one or more upper rotating rods 201 extends out of the outer shell 100 and forms a power connection with the motor 107 through a power transmission member. The upper rotating rod 201 can be driven by the motor 107 to rotate, thereby moving the metal strip 204. The moving direction of the metal strip 204 in a continuously bent shape is opposite to the flow direction of the exhaust gas in the continuously bent area. Its significance lies in that as the exhaust gas continues to flow, the oil mist component in the exhaust gas is continuously affected by the electrostatic field and is stained on the outer surface of the metal strip 204, that is, as the exhaust gas flows in the direction, the exhaust gas continues to become drier. The metal strip 204 is clean, and the oil mist component on the outer surface of the metal strip 204 becomes less. Since the cleaner the outer surface of the metal strip 204 is, the better the purification effect is. Therefore, this method can greatly increase the oil mist purification effect of the exhaust gas. It should be noted that as the metal strip 204 continues to move, the metal strip 204 will be subjected to the oil scraping treatment of the oil scraping mechanism 300 when it moves to the position of the lower rotating roller 202. After being scraped clean, it will return and continue to form a continuous bending area. The metal strip 204 in the continuous bending area still maintains a mode in which the closer it is to the exhaust gas outlet pipe 102, the cleaner the outer surface is, and the better the purification effect is.

[0040] In the preferred embodiment, the turning of the metal strip 204 is realized by simply relying on the two side turntables 203 located between the two adjacent upper turntables 201, which is not smooth enough. Figure 4 A pull-down rod 206 parallel to the upper turning rod 201 is provided below the continuous bending area. The pull-down rod 206 is tangent to the bottom of the metal strip 204 in the continuous bending area. The pull-down rod 206 is made of a magnet. The metal strip 204 has magnetism, and the inner surface of the metal strip 204 is not stained with oil mist and is clean. Therefore, a downward pulling force is applied to the bottom of the metal strip 204 in the continuous bending area through the magnetic force of the pull-down rod 206 to ensure that the turning of the metal strip 204 is smooth.

[0041] In a preferred embodiment, the industrial waste gas with oil mist components generally has a higher temperature, and the lower the temperature, the easier it is for the oil mist components to be captured by the electrostatic field. Figure 1 , Figure 4 and Figure 6A contact assembly 207 is disposed below each upper rotating rod 201. The contact assembly 207 includes an inner pipe 2071 parallel to the upper rotating rod 201 and a plurality of fins 2072 arranged in an array on the outer surface of the inner pipe 2071. The ends of the fins 2072 are close to the metal strip 204. The inlet ends of the inner pipes 2071 of the plurality of contact assemblies 207 extend out of the outer shell 100 and are connected through the cold air inlet pipe 103. A cold air outlet pipe 104 is also disposed on the outer surface of the outer shell 100. A sleeve 105 is disposed on the outside of the exhaust gas inlet pipe 101. The sleeve 105 is connected to the cold air outlet pipe 104. An exhaust nozzle 106 extends from the outer circumferential surface of the sleeve 105. The significance of this is that after the cold air enters the outer shell 100 through the cold air inlet pipe 103 and the inner pipe 2071, it is discharged from the cold air outlet pipe 104. In this process, the heat exchange between the cold air and the metal strip 204 is improved by the fins 2072, thereby indirectly realizing the cooling of the exhaust gas. The oil mist component in the exhaust gas after the temperature drops is more easily captured by the electrostatic field. It should be noted that the manufacture of cold air is achievable with existing technology and will not be elaborated on. In addition, the temperature of the cold air discharged from the cold air outlet pipe 104 is still lower than that of the exhaust gas. Therefore, the discharged cold air can be discharged through the sleeve 105 and the exhaust nozzle 106 to cool the exhaust gas in the exhaust gas inlet pipe 101.

[0042] Oil scraper mechanism 300:

[0043] Reference Figure 2 and Figure 3 The oil scraping mechanism 300 is located below the metal strip 204 and includes a longitudinal oil scraping component and a transverse oil scraping component.

[0044] Reference Figure 7 and Figure 8 The longitudinal scraper component includes a longitudinal scraper 301 that is attached to the outer surface of the metal strip 204. The blade of the longitudinal scraper 301 consists of two oblique blades, and the distance between the two oblique blades increases along the moving direction of the metal strip 204. Furthermore, a heating element 302 is arranged in the longitudinal scraper 301, which can be realized by existing heating technology and will not be elaborated. After the longitudinal scraper 301 is heated, it has the effect of a hot knife cutting butter, and can better scrape off the oil mist component on the metal strip 204.

[0045] Reference Figure 7 and Figure 8 The horizontal oil scraping component includes a liquid storage box 303, in which a degreasing medium is stored, such as a kitchen oil stain remover in the prior art, which will not be described in detail. An ultrasonic atomizing element 305 is also provided in the liquid storage box 303, which can atomize the degreasing medium. The atomized degreasing medium rises and contacts the metal strip 204. The ultrasonic atomizing element 305 can be realized by the prior art and will not be described in detail.

[0046] The box opening of the liquid storage box 303 is provided with an oil scraping component 304, and the oil scraping component 304 includes a synchronous belt whose moving direction is parallel to the width direction of the metal strip 204. The outer surface of the synchronous belt is provided with a plurality of scrapers in an array along the extension direction. The scrapers are made of rubber material. The scrapers can contact the metal strip 204, and the oil mist components on the metal strip 204 stained with the atomized oil removal medium can be easily scraped off by the scrapers. It should be noted that the metal strip 204 serves as a dust collecting electrode, and the current is very small. As long as the outer shell 100 is well grounded, electric shock accidents will basically not occur. Furthermore, the oil removal medium can be selected from liquids with insulating properties.

[0047] In a preferred embodiment, a blower 306 is provided in front of the transverse oil scraping member along the moving direction of the metal strip 204 , the purpose of which is to dry the metal strip 204 by the blower 306 , and the drying is aimed at the atomized oil removal medium remaining on the metal strip 204 .

[0048] A treatment method for industrial waste gas using oil mist treatment equipment:

[0049] Step 1: The exhaust gas enters the continuous bending area through the exhaust gas inlet pipe 101. In the continuous bending area, the oil mist component in the exhaust gas is stained on the outer surface of the metal strip 204 by the electrostatic field. The exhaust gas after the oil mist component is removed is discharged through the exhaust gas outlet pipe 102.

[0050] Step 2: The motor 107 drives the upper rotating roller 201 to rotate, thereby driving the metal strip 204 to move. The moving direction of the metal strip 204 constituting the continuous bending area is opposite to the flow direction of the exhaust gas in the continuous bending area. During the movement of the metal strip 204, the oil scraping mechanism 300 is used to scrape the oil on the outer surface of the metal strip 204.

[0051] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
