Description

Technical Field

[0001] The present invention relates to a low environmental load type waste gas treatment device, and particularly to an oil fume removal and deodorization purification device that can continuously and efficiently remove oil, dust particles, and malodorous gases in waste gas while carbonizing and treating agricultural residues and organic wastes.

Background Art

[0002] As people's environmental awareness increases, the treatment methods for agricultural residues (such as rice straw, fruit husks, waste wood, etc.) and various organic wastes have changed from conventional direct incineration to pyrolysis or carbonization treatment, combining environmental protection and resource recycling.

[0003] However, during the initial stage and the progress of carbonization or gasification cracking of the above-mentioned wastes, a large amount of thick smoke, irritating odors, tar (wood tar), and suspended particles (dust) may often be generated. If they are directly discharged into the atmosphere without effective treatment, it will not only cause severe air pollution but also violate the current environmental protection laws and regulations.

[0004] Most existing waste gas treatment devices adopt a single water washing method or a simple activated carbon filtration method. When performing such pretreatment purification operations, they generally lack effective overall protection and continuous separation design. Existing equipment often faces technical drawbacks such as insufficient filtration effects, rapid clogging of pipes due to tar adhesion, and very early consumption of filtration members when dealing with carbonized waste gas containing high-viscosity tar, fine dust, and complex odor components. This forces the operator to frequently stop the operation during actual operation to clean the inside, maintain the pipes, and replace the filtration members, which not only takes time and effort but also brings great inconvenience in use and cost burden to the entire waste gas treatment process.

[0005] Therefore, developing an integrated equipment that can continuously and efficiently block oil fume and dust and remove residual smoke and multiple deodorization by high-temperature pyrolysis has become an urgent problem to be solved by the industry.

Summary of the Invention

[0006] This invention proposes an oil mist removal and deodorization purification device that achieves multiple purification effects—highly efficient separation of oil and water, blocking of suspended particles, odor removal, and incineration of residual smoke—when purifying exhaust gas and oil mist generated in a pyrolysis vaporization furnace. This is achieved by dividing the filtration unit for removing oil mist and odors into multi-stage spaces for spray absorption and oil overflow separation using multiple partition plates inside, and adding a means of spraying oil contaminants into the liquid by spraying from top to bottom with a spray assembly, in addition to precisely arranging mechanisms such as a fluid circulation filtration closed circuit, deodorizing filtration members, a high-temperature electric heating device for removing oil mist and odors, and an end-point cleaning device. This fundamentally solves the technical defects of current technology, where exhaust gas is not treated thoroughly and piping and power components easily become clogged with tar or dust accumulation, thereby greatly improving the ease of operation of the overall exhaust gas treatment process, the service life of the equipment, and the environmental protection effect of continuous operation. [Means for solving the problem]

[0007] The oil smoke removal and deodorization and purification device according to this invention comprises a thermal decomposition vaporization furnace, a filtration unit for removing oil smoke odors, a smoke introduction pipe, a liquid circulation unit, an electric heating furnace for removing oil smoke odors, and an exhaust power unit.

[0008] The filtration unit for removing oil mist and odor has multiple partition plates arranged inside, thereby dividing it into multiple interconnected processing sections, and storing absorbent liquid within each of these processing sections. Each of the multiple partition plates is provided with a connecting channel for a specific fluid to flow across the section, and an oil discharge connection is provided outside one of the processing sections for discharging surface oil, and a deodorizing filtration member is attached to one of the multiple connecting channels.

[0009] The smoke introduction pipe is connected between the pyrolysis vaporization furnace and the oil smoke and odor removal filtration unit, and is used to guide the oil smoke and waste gas generated in the pyrolysis vaporization furnace into the oil smoke and odor removal filtration unit.

[0010] The liquid circulation unit draws out the absorbent liquid from the oil mist odor removal filtration unit, passes it through an impurity filter, and then sends it to a plurality of spray assemblies installed in a plurality of processing sections. The plurality of spray assemblies then spray the atomized absorbent liquid from top to bottom towards each processing section.

[0011] The electric heating furnace for removing oil mist and odor has a mist inlet end that communicates with one of the multiple processing sections of the oil mist and odor removal filtration unit, and uses electricity to generate a high temperature to heat the remaining mist that has passed through, thereby removing the oil mist and odor at a high temperature.

[0012] The exhaust power unit is used to communicate with the electric heating furnace for removing oil fumes and odors, to create a negative pressure suction state inside the entire apparatus, and to guide the purified gas through an air purifier before discharge. [Effects of the Invention]

[0013] This invention achieves excellent environmental purification by continuously and efficiently removing oil, smoke, and odors from exhaust gas through a multi-layered coordinated operation: spraying oil mist from top to bottom in a section to capture it, automatically discharging the oil by overflow separation, circulating and filtering the fluid in a closed circuit, physically adsorbing it using a deodorizing filter member, and removing oil mist odors at the end using high-temperature electric heating.

[Modes for carrying out the invention]

[0015] We will now further describe the present invention in conjunction with drawings of preferred embodiments of the present invention so that those skilled in the art may carry out the present invention in accordance with the description herein.

[0016] As shown in Figure 1-4, this invention proposes an oil mist removal and deodorization purification device for purifying exhaust gases while carbonizing and pyrolysis-treating agricultural residues and organic waste. The oil mist removal and deodorization purification device comprises a pyrolysis vaporization furnace 10, a filtration unit 20 for removing oil mist odors, a mist introduction pipe 30, a liquid circulation unit 40, an electric heating furnace 50 for removing oil mist odors, and an exhaust power unit 60.

[0017] The top of the pyrolysis vaporization furnace 10, which serves as the main reaction furnace body for pyrolysis processing, can be equipped with a sealed lid 11 that can be opened and closed for loading and sealing.

[0018] The filtration unit 20 for removing oil fume and strange odor has a multi-stage core structure for oil removal, deodorization, and oil-water separation. As shown in FIGS. 3-4, the internal space of the filtration unit 20 for removing oil fume and strange odor is partitioned horizontally by a first partition plate 21 and a second partition plate 22 (i.e., a plurality of partition plates), and is successively partitioned into a first oil fume and strange odor absorption section 20A, a second oil fume and strange odor absorption section 20B, and an independent air chamber 20C from left to right (in accordance with the direction in the figure). Absorbent liquid W (specifically referring to an aqueous solution formulated with a specific ratio and added with an enzyme in this embodiment) with a predetermined height and volume is stored inside the first oil fume and strange odor absorption section 20A, the second oil fume and strange odor absorption section 20B, and the independent air chamber 20C.

[0019] Particularly, as shown in the partial enlarged view of FIG. 4, a through gas-liquid communication port 211 is provided at an appropriate position of the first partition plate 21 close to the upper end. The gas-liquid communication port 211 is used for the surface liquid layers of the first oil fume and strange odor absorption section 20A and the second oil fume and strange odor absorption section 20B to communicate with the gas space as a specific form of the communication flow path. The key is that the bottom of the first partition plate 21 does not contact the bottom surface of the filtration unit 20 for removing oil fume and strange odor, maintaining a certain distance, that is, forming a bottom gap, so that the bottom layer liquids at the bottoms of the first oil fume and strange odor absorption section 20A and the second oil fume and strange odor absorption section 20B can communicate with each other.

[0020] Similarly, as shown in FIG. 4, a gas inlet 221 is provided at an appropriate position of the second partition plate 22 close to the upper end. The gas inlet 221 is also used for the second oil odor absorption section 20B to communicate with the gas space of the independent air chamber 20C as a specific form of the communication flow path. At an inner position of the second oil odor absorption section 20B adjacent and in close contact with the gas inlet 221, a deodorization filtration member 23 (in this embodiment, the deodorization filtration member 23 is specifically a porous activated carbon filtration mesh, and other equivalent activated carbon particle filtration cores, photocatalyst filtration members, or chemical adsorption layers capable of performing deodorization and gas adsorption functions can also be adopted) is provided. The bottom end of the second partition plate 22 also has a bottom gap without contacting the bottom surface of the housing, so that the second oil odor absorption section 20B can communicate with the liquid at the bottom of the independent air chamber 20C.

[0021] Externally, as shown in FIGS. 3-4, an oil discharge connection part 24 is provided on the front outer side of the filtration unit 20 for removing oil fume and abnormal odor, and the oil discharge connection part 24 communicates with the second oil odor absorption area 20B inside. The key is that the height of the oil discharge connection part 24 located on the housing exactly corresponds to the height of the bottom edge of the gas-liquid communication port 211 located on the first partition plate 21, which helps to automatically overflow and discharge the floating oil on the surface through the balance of the liquid level.

[0022] As shown in FIGS. 1-3, one end of the smoke introduction pipe 30 is connected to the waste gas discharge port of the pyrolysis gasification furnace 10, and the other end extends to penetrate the top surface of the first oil fume and abnormal odor absorption area 20A of the filtration unit 20 for removing oil fume and abnormal odor from top to bottom. And a smoke discharge port 31 with a specific pipe diameter is formed inside the smoke introduction pipe 30.

[0023] Regarding the fluid circulation part, as shown in FIGS. 1-3, the liquid circulation unit 40 has a hydraulic pump 41, a first water supply pipe 42, a second water supply pipe 43, and an impurity filter 44 connected in series to the second water supply pipe 43. In this embodiment, the hydraulic pump 41 is placed in an independent power housing 70 together with the following exhaust power unit 60. The water introduction end of the hydraulic pump 41 sucks out the absorption liquid W at the bottom of the filtration unit 20 for removing oil fume and abnormal odor through the first water supply pipe 42, and the water discharge end of the hydraulic pump 41 is connected to the second water supply pipe 43.

[0024] As shown in Figure 3-4, the water flow after passing through the impurity filter 44 is divided and sent to a plurality of spray assemblies installed on each treatment section. In this embodiment, the plurality of spray assemblies have a plurality of first diversion pipes 45 installed above the housing of the first oil mist odor absorption section 20A. The plurality of first diversion pipes 45 (in this embodiment, three first diversion pipes 45 are arranged) are installed across the top surface of the housing of the oil mist odor removal filtration unit 20 and extend downward into the interior of the housing, and a plurality of first atomizing nozzles 451 installed facing downward are connected to the lower end of each first diversion pipe 45. Similarly, the plurality of spray assemblies further have a plurality of second diversion pipes 46 installed above the housing of the second oil mist odor absorption section 20B. Multiple second diversion pipes 46 are similarly installed across the top surface of the box and extend downward into the interior of the box, and at least one downward-facing second atomizing nozzle 461 is connected to the lower end of each second diversion pipe 46. This structural arrangement makes it possible to spray the atomizing absorbent liquid from top to bottom towards each processing section. The key is that both the first diversion pipe 45 and the second diversion pipe 46 are in communication with the second water supply pipe 43 and both receive fluid from the hydraulic pump 41 and transmit it under pressure.

[0025] As shown in Figure 1-3, the outer shell of the electric heating furnace 50 for removing oil mist and odor can be installed on the side or front of the oil mist and odor removal filtration unit 20. The electric heating furnace 50 for removing oil mist and odor has a mist inlet that communicates with multiple independent air chambers 20C of the oil mist and odor removal filtration unit 20, and generates high temperatures using electricity. The inside of the electric heating furnace 50 for removing mist and odor has a high-power electric heating element and a spiral passage for extending the heating time in the airflow, and is used to heat the mist to a high temperature to achieve the purpose of heating, smoke removal, and deodorization.

[0026] The exhaust power unit 60 includes a first exhaust pipe 61, a blower 62, and a second exhaust pipe 63. One end of the first exhaust pipe 61 is connected to the exhaust end of the electric heating furnace 50 for removing oil fumes and odors, and the other end is connected to the air inlet end of the blower 62. The air outlet end of the blower 62 is connected to the second exhaust pipe 63, and the end pipe opening of the second exhaust pipe 63 extends upward and has an air purifier 64, thereby ensuring that the final filtration is carried out.

[0027] In addition, the device according to this invention includes a main control panel 71 electrically connected to internal electrical control elements for operating and displaying the overall operating status of the device. Multiple wheels 72 are provided at the four corners of the bottom of the entire device to facilitate movement and flexible deployment of the entire device.

[0028] Next, we will explain the operating process of the apparatus and the direction of gas-liquid flow.

[0029] Please refer to the fluid trajectory and arrow direction as shown in Figure 5-9. During use, the blower 62 of the exhaust power unit 60 operates to maintain a stable negative pressure suction state in the internal piping and space from each processing section of the pyrolysis vaporization furnace 10, the mist introduction pipe 30, and the oil mist odor removal filtration unit 20 to the oil mist odor removal electric heating furnace 50.

[0030] The oily fumes and odors are sprayed and collected from top to bottom, causing the oil stains to settle (first oily fumes and odor absorption section 20A). As shown in Figures 5 and 7-8, the high-temperature oily fumes waste gas generated when the pyrolysis vaporizer 10 carbonizes agricultural residues is sucked in by negative pressure and discharged through the mist introduction pipe 30 to the top of the first oily fumes and odor absorption section 20A of the oily fumes and odor removal filtration unit 20 from the mist outlet 31. As shown in Figure 5, when the entire system is in operation, the high-temperature oily fumes waste gas generated in the pyrolysis vaporizer 10 is sucked in by negative pressure along the mist introduction pipe 30 and guided into the oily fumes and odor removal filtration unit 20. At this time, the hydraulic pump 41 of the liquid circulation unit 40 continuously draws up the enzyme absorption liquid W stored at the bottom and sprays a dense atomized absorption liquid from top to bottom through multiple first atomizing nozzles 451. When the high-temperature oil mist exhaust gas comes into contact with the atomized droplets above the first oil mist odor absorption section 20A, it is rapidly cooled, and the high-viscosity tar and grease contained in the exhaust gas are powerfully captured by the dense atomized absorbent liquid and directly transported together with the atomized absorbent liquid to the enzyme absorbent liquid below, achieving excellent results in initial oil mist collection and dust sedimentation.

[0031] As the liquid level maintains equilibrium and the oil overflows automatically: As shown in Figure 6-8, the tar absorbed into the liquid floats and accumulates on the surface liquid layer of the first oil mist odor absorption section 20A due to its own specific gravity. With the continuous spraying of the absorbent liquid and fluctuations in the liquid level, the tar layer on the surface flows into the second oil mist odor absorption section 20B through the gas-liquid communication port 211 that approaches the upper end of the first partition plate 21. The oil stains accumulated on the liquid surface of the second oil mist odor absorption section 20B can be automatically discharged and collected outside the box from the oil discharge connection 24 because the height of the oil discharge connection 24 corresponds to the gas-liquid communication port 211, thereby preventing the repeated accumulation of oil stains inside the box and causing secondary contamination or clogging of the piping.

[0032] A delicate two-stage atomization absorption process is performed, followed by adsorption and deodorization by the deodorizing filter: As shown in Figure 7-8, the gas, having undergone the initial oil mist removal in the first stage, is similarly guided to the second oil mist odor absorption section 20B through the gas-liquid communication port 211 at the upper end of the first partition plate 21. Here, the second atomization nozzle 461 sprays the atomizing absorption liquid onto the gas again from top to bottom to perform secondary precise collection, causing any remaining fine suspended particles to fall completely into the liquid. Subsequently, under the action of strong negative pressure, the gas is forced to pass through the deodorizing filter 23 installed at the gas inlet 221. Due to its strong physical adsorption properties caused by its porous filtration structure, it thoroughly adsorbs and filters out complex and irritating odor molecules in the gas, deodorizing it, and then flows into the independent air chamber 20C through the gas inlet 221.

[0033] Oil fumes are removed, deodorized, and safely discharged through electric high-temperature incineration: As shown in Figure 9, the gas entering the independent air chamber 20C contains almost no dust, particles, or tar, but a small amount of insoluble thermal decomposition residual fumes is mixed in. At this time, the gas is completely drawn into the electric heating furnace 50 for oil fumes and odor removal and proceeds along the spiral passage inside it. The high heat generated by electricity using the electric heating element inside the furnace heats the fumes and residual gas to a very high temperature, thoroughly incinerating them in the spiral passage and achieving the objective of "oil fumes removal and deodorization at high temperatures." Finally, the completely purified clean gas enters the blower 62 via the first exhaust pipe 61, is pushed into the second exhaust pipe 63, passes through the air purifier 64 for final filtration, and is finally safely discharged into the atmosphere in a smokeless, odorless, and oil-free state that fully complies with environmental standards.

[0034] The oil mist removal and deodorizing / purification equipment according to this invention can achieve the following specific effects during actual operation.

[0035] 1. Oil collection and automatic overflow separation by powerful spray: When the exhaust gas is introduced into the oil mist and odor removal filtration unit 20, multiple spray assemblies spray a dense atomized absorbent liquid from top to bottom. This powerfully captures high-viscosity tar and oil in the exhaust gas with a dense mist, causing it to flow into the absorbent liquid W below, where it separates into layers and floats on the liquid surface. Furthermore, the design of conjugating the gas-liquid communication port 211 of the first partition plate 21 to the horizontal height of the oil discharge connection part 24 allows the oil to automatically overflow and be discharged by the equilibrium of the liquid levels, preventing tar from adhering to the piping and various power components.

[0036] 2. Multi-stage double oil mist removal effect: This invention employs a dual method of "physical atomization absorption" and "end-level high-temperature conversion" for the smoke components in the exhaust gas. First, multiple spray assemblies are used to capture solid coal residue and fine dust in the exhaust gas from top to bottom with mist droplets, causing them to settle and flow into the absorption liquid W. The remaining trace amounts of insoluble residual smoke are then guided by negative pressure into the electric heating furnace 50 for oil mist and odor removal, where high-temperature incineration is performed using the high temperature generated by electricity to remove the oil mist and achieve complete smokeless emission.

[0037] 3. Fluid-based decomposition and multiple deodorization by porous structure: This invention uses blendable enzyme components in the absorbent liquid W to induce initial catalytic neutralization and decomposition reactions on organic odor molecules flowing into the liquid. Before the airflow leaves the oil mist odor removal filtration unit 20, it is forced to pass through the structure of the deodorizing filtration member 23, where it undergoes strong physical adsorption or chemical neutralization, achieving excellent deodorization and purification effects on exhaust gases.
