Description

Technical Field

[0001] The present invention relates to the technical field of environmental engineering, and specifically to an oily sludge collection device. Background Art

[0002] As solid waste generated during oil and gas development, petroleum refining, transportation and storage, etc., oily sludge has complex components and great harm. It is an emulsion formed by the mixture of oil, water and solid phases, containing various organic pollutants and heavy metal pollutants, and is listed in the "Waste Mineral Oil and Oil-Containing Waste (HW08)" in the national hazardous waste list. The heavy metals and some compounds contained in it are toxic and harmful to the human body, and crude oil and inorganic and organic compounds will cause soil deterioration and surface water pollution. However, oily sludge also contains a certain amount of oil-phase substances, which are recyclable resources, and it is urgent to carry out harmless and resource-based treatment on it.

[0003] To improve the pyrolysis effect of oily sludge, it is found that co-pyrolysis of oily sludge with catalytic substances is one of the effective ways. Biomass such as crop straw, etc., has a wide source, a high volatile content and a low ash content. When co-pyrolyzed with oily sludge, it can improve the pyrolysis conversion rate, increase the yield and quality of pyrolysis products, and its catalytic effect has received wide attention. However, in the actual operation of co-pyrolysis of oily sludge and biomass, the existing oily sludge collection and treatment devices have many deficiencies.

[0004] The existing oily sludge collection devices mainly focus on the collection and preliminary separation of oily sludge, and lack targeted design in the aspect of collaborative treatment with biomass. On the one hand, in the biomass feeding link, it is difficult to achieve precise equal-dose feeding. This results in the difficulty of accurately controlling the ratio of biomass to oily sludge during co-pyrolysis, and it is impossible to ensure that each co-pyrolysis reaction is in the best conditions, thereby affecting the quality and yield of pyrolysis products. On the other hand, the existing devices cannot flexibly adjust the feeding amount of biomass according to the different viscosities of oily sludge. The viscosity difference of oily sludge will affect its mixing effect and reaction process with biomass. Oily sludge with high viscosity requires more biomass to improve its pyrolysis performance, but the existing devices are difficult to meet this requirement.

[0005] In addition, during the process of biomass being fed into oily sludge, there is a lack of an effective diffusion mechanism. Biomass is usually fed into oily sludge in a simple way, resulting in uneven distribution in the oily sludge, unable to fully contact and react, reducing the efficiency and effect of co-pyrolysis. This not only causes waste of resources, but also makes the harmless and resource-based treatment of oily sludge difficult to achieve the expected goal, restricting the development of the oily sludge treatment industry.

[0006] Therefore, an oily sludge collection device is proposed to solve the above problems. Summary of the Invention

[0017] Compared with the prior art, the present invention provides an oily sludge collection device, which has the following beneficial effects: 1. Through the setting of the material feeding adjustable mechanism, under the action of the adjusting groove, the biomass in the storage hopper is equally divided and intermittently fed into the collection bin, ensuring that the biomass content in the oily sludge input each time is consistent, maintaining a stable reaction environment, avoiding the fluctuation of the reaction rate caused by the fluctuation of the biomass input, assisting the stable progress of pyrolysis, fermentation and other reactions, ensuring the consistency of the treatment effect. In the pyrolysis reaction, a stable biomass input can ensure the stability of the pyrolysis temperature and the product generation ratio, enabling the biomass to fully and evenly contact with the oily sludge, making the reaction proceed under the best ratio, improving the quality stability of pyrolysis oil and pyrolysis gas, promoting the cracking of macromolecular organic matter in the oily sludge, increasing the yield of pyrolysis oil and pyrolysis gas, improving the resource recovery rate. At the same time, it can reduce the unreacted substances remaining in the pyrolysis slag and improve the product quality.

[0018] 2. By setting the carrier, under the control of the forward and reverse rotation of the driving disk, the position of the carrier in the adjustment groove is adjusted. Furthermore, according to different properties of oily sludge and the differences in its internal components and structures, different amounts of biomass can be put in for pyrolysis reaction, so that the biomass and the oily sludge can reach the optimal reaction ratio, providing suitable active substances for the pyrolysis reaction, better promoting the cracking and conversion of oil components, increasing the yield and quality of pyrolysis oil. Precise dosing adjustment can make full use of the resources in the oily sludge, promote the thermal cracking of macromolecular hydrocarbons in the oily sludge, convert more oil components into recoverable pyrolysis oil and gaseous products, reduce the residual oil amount in the pyrolysis slag, improve the resource recovery rate, avoid the overuse or insufficiency of biomass, and then optimize the energy consumption of processes such as pyrolysis, and better enable the reaction to proceed under more energy-saving conditions.

[0019] 3. By setting the multi-range dispersion treatment mechanism, under the setting of the inner and outer parts of the cone body and the reverse rotating body, the conical arc surface exerts forces in different directions on the biomass falling from above, changing the falling trajectory of the biomass, making it spread around and disperse more evenly in the horizontal direction, increasing the contact area with the oily sludge, preventing the biomass from concentrating in a certain area, ensuring its full mixing with the oily sludge, creating good conditions for the subsequent reaction, improving the co-treatment effect, and making the heat transfer and mass transfer processes between the biomass and the oily sludge more efficient, increasing the yield and quality of pyrolysis oil, and then making the substances collected after stratification purer, promoting the efficient resource utilization of oily sludge.

[0020] 4. Driven by the driving source, the inner arc groove and the bidirectional slider are used in cooperation, and then the cone body and the reverse rotating body perform reverse rotational movements. While dispersing the falling biomass, it continuously and stably guides the biomass, reducing the fluctuations in the treatment process caused by uneven biomass distribution. Furthermore, the centrifugal force generated by the rotation of the reverse rotating body makes the biomass spread around, expanding the distribution range of the biomass. The reverse rotation of the cone body further changes the movement trajectory of the biomass, making biomass particles dispersed both inside and outside, increasing the degree of dispersion of the biomass. The double settings inside and outside enable the biomass to be dispersed in the collection bin over a larger range, preventing the aggregation of the biomass, creating favorable conditions for the subsequent full mixing with the oily sludge, promoting the contact area between the two, and then enabling the reaction to be more sufficient in the subsequent treatment process.

[0039] For a further embodiment: Please refer to Figures 7 to 10As shown in the figure: The multi-range dispersion processing mechanism 3 is used to sprinkle the input biomass over a wide range onto the oily sludge for mixing. The multi-range dispersion processing mechanism 3 includes a feeding pipe 31, which is fixedly connected to the bottom of the material distribution bin 22. At the end of the feeding pipe 31 far from the material distribution bin 22, a cross 32 is fixedly connected. In the middle of the cross 32, a driving source 33 is fixedly connected. The driving source 33 consists of a driving motor and a conical block. The upper part of the driving source 33 is conical. At the end of the driving source 33 far from the cross 32, a cone body 34 is fixedly connected. The cone body 34 is driven by the driving motor in the driving source 33 and is fixedly connected to the output shaft of the driving motor. The outer circle of the cone body 34 is a conical arc surface. At the end of the cone body 34 far from the driving source 33, a movable cavity 35 is opened. On the inner wall surface of the cone body 34, inner arc grooves 36 are symmetrically opened in two and are connected to each other.

[0040] The multi-range dispersion processing mechanism 3 further includes a bidirectional slider 37. The bidirectional slider 37 is mainly used to drive the bidirectional slider 37 to slide on the vertical groove 39 when the cone body 34 rotates forward, so as to drive the outer arc groove body 310 to drive the reverse rotating body 312 to rotate in the reverse direction. The bidirectional slider 37 is slidably connected to the inner arc groove 36. On both sides of the bidirectional slider 37, sliding columns are provided. An outer arc groove body 310 is rotatably connected inside the cone body 34. The arc-shaped groove on the outer arc groove body 310 is arranged in the opposite direction to the inner arc groove 36.

On the outer circle of the outer arc groove body 310, two arc-shaped grooves are symmetrically opened. An L-shaped positioning body 38 is fixedly connected to the outer circle of the outer arc groove body 310. On the bottom surface of the L-shaped positioning body 38, a fixing column penetrates the outer arc groove body 310 and is fixedly connected to the cone body 34. On the side of the L-shaped positioning body 38 close to the circumferential surface of the outer arc groove body 310, a vertical groove 39 is opened. The bidirectional slider 37 is slidably connected to the vertical groove 39. The side of the bidirectional slider 37 far from the inner arc groove 36 is slidably connected to the outer arc groove body 310. A multi-link 311 is fixedly connected to the side of the outer arc groove body 310 far from the cone body 34. An outer ring of the multi-link 311 is fixedly connected to a reverse rotating body 312. The reverse rotating body 312 and the outer arc surface of the cone body 34 are mainly used for multi-range guiding and dispersing operations of biomass solid particles. The reverse rotating body 312 is arranged on the outer circle of the cone body 34.

[0041] The working principle of all the content in the above embodiments is as follows: The following is the working process of the adjustable material feeding mechanism 2 for equally dividing and feeding the biomass used for the three-phase separation of the oil-containing sludge placed in the collection bin 1, and the feeding amount can be adjusted according to the density of the oil-containing sludge: When in use, during the initial separation of the oil-containing sludge collected in the collection bin 1, when the biomass is fed and cooperates with it to carry out three-phase separation, the bearing plate 23 is started by an external driving device and rotates forward. During the forward rotation of the bearing plate 23, under the action of gravity, the biomass solid particles stored in the storage hopper 21 flow into the adjustment groove 24 and are initially stored in the carrier 211. When the adjustment groove 24 rotates, it drives the internal carrier 211 and other structures to rotate forward synchronously. Then, when it rotates 180 degrees, the adjustment groove 24 deflects from below the storage hopper 21 to directly above the feeding pipe 31. At this time, under the continuous action of gravity, the biomass stored in the carrier 211 falls. Under the action of multiple adjustment grooves 24, the biomass stored in the storage hopper 21 is equally divided and then fed into the collection bin 1 to better control the feeding content of the biomass.

[0042] Further, when the operator detects that different amounts of biomass need to be fed according to the oil-containing sludge with different characteristics, if the oil content of the oil-containing sludge is high and more biomass is required to provide additional carbon and hydrogen sources during pyrolysis to promote the cracking of macromolecular hydrocarbons and improve the product and quality of pyrolysis oil, the driving disk 28 rotates reversely under the drive of an external driving device. At this time, under the reverse rotation of the driving disk 28, the guiding groove 29 synchronously deflects reversely with the center of the driving disk 28 as the center. During the deflection process, the sliding rod 210 sliding in the guiding groove 29 is driven to contract towards the center with the center of the expansion groove 27 as the center. At this time, when the sliding rod 210 contracts towards the center of the expansion groove 27, with the assistance of the auxiliary groove on the expansion groove 27 and the sliding groove 25, it slides horizontally inward. Furthermore, the contraction of the sliding rod 210 drives the carrier 211 to approach the expansion groove 27, thereby controlling the carrier 211 to slide towards the center of the bearing plate 23 within the adjustment groove 24, expanding the volume of the cavity formed by the adjustment groove 24 and the carrier 211, loading more biomass to assist the decomposition operation of the oil-containing sludge; conversely, the driving disk 28 is rotated forward to cause the sliding rod 210 to push the carrier 211 to slide towards the outer ring of the bearing plate 23, reducing the device volume of the adjustment groove 24 and reducing the volume of the equal amount of biomass.

[0043] By setting the adjustable material delivery mechanism 2, under the action of the regulating tank 24, the biomass in the storage hopper 21 is divided into equal amounts and intermittently delivered to the collecting bin 1 to ensure that the biomass content in the oily sludge is consistent each time, maintain a stable reaction environment, avoid the reaction rate being fast and slow due to fluctuations in biomass input, assist in the stable advancement of reactions such as pyrolysis and fermentation, and ensure the consistency of treatment effects. In the pyrolysis reaction, a stable biomass input amount can ensure the stability of the pyrolysis temperature and the product generation ratio, so that the biomass and the oily sludge are fully and evenly contacted, so that the reaction is carried out at the optimal ratio, improve the quality stability of the pyrolysis oil and the pyrolysis gas, promote the cracking of large molecular organic matter in the oily sludge, increase the output of pyrolysis oil and pyrolysis gas, and improve the resource recovery rate. At the same time, it can reduce the unreacted substances remaining in the pyrolysis residue and improve the product quality.

[0044] By setting the carrier 211, under the control of the forward and reverse rotation of the driving disk 28, the position of the carrier 211 in the adjustment tank 24 is adjusted, and then different amounts of biomass can be added for pyrolysis reaction according to the different properties of oily sludge, based on the differences in its internal composition and structure, so that the biomass and oily sludge can reach the best reaction ratio, provide suitable active substances for the pyrolysis reaction, better promote the cracking and conversion of oil, and improve the yield and quality of pyrolysis oil. Accurate addition and adjustment can make full use of the resources in the oily sludge, promote the thermal cracking of large molecular hydrocarbons in the oily sludge, convert more oil into recoverable pyrolysis oil and gaseous products, reduce the amount of residual oil in the pyrolysis residue, improve the resource recovery rate, avoid excessive or insufficient use of biomass, and optimize the energy consumption of pyrolysis and other treatment processes, so that the reaction can be carried out under more energy-saving conditions.

[0045] Please refer to the above working process Figures 1 to 6 .

[0046] The working process of the multi-range dispersion treatment mechanism 3 for dropping the fed biomass in multiple ranges onto the oily sludge for mixing is as follows: When in use, the biomass evenly divided in the material feeding adjustable mechanism 2 drops from the feeding pipe 31, and the biomass drops above the multi-range dispersion treatment mechanism 3. Then, under the combined action of the conical body 34 and the outer arc surface of the reverse rotating body 312, it circulates in multiple ranges into the collection bin 1. The drive source 33 is started through the external controller to connect the power supply. The drive source 33 drives the conical body 34 to rotate forward. Since the inner arc groove 36 is opened in the conical body 34 and the two-way slider 37 is slidably connected to the inner arc groove 36, the forward rotation of the conical body 34 drives the two-way slider 37 slidably connected in its inner arc groove 36 to slide synchronously. The sliding of the two-way slider 37 is reciprocally moved in the vertical direction in the vertical groove 39 opened in the L-shaped positioning body 38. Thus, when reciprocally moving, the drive of the inner arc groove 36 on the two-way slider 37 is converted into the drive of the two-way slider 37 on the outer arc groove body 310, so as to drive the outer arc groove body 310 to perform a rotational movement in the opposite direction to the inner arc groove 36. Therefore, under the connection of the outer arc groove body 310 and the multi-link 311 and the control of the reverse rotating body 312, when the drive source 33 drives the conical body 34 to rotate forward, under the transmission and cooperation of structures such as the inner arc groove 36, the reverse rotating body 312 is driven to perform a reverse rotational movement, so that the biomass dropped from above is scattered in multiple ranges into the collection bin 1 through the reverse rotational conduction of the conical body 34 and the reverse rotating body 312.

[0047] Through the setting of the multi-range dispersion treatment mechanism 3, under the internal and external settings of the conical body 34 and the reverse rotating body 312, the arc surface of the cone exerts forces in different directions on the biomass falling from above, changing the falling trajectory of the biomass, making it spread around and disperse more evenly in the horizontal direction, increasing the contact area with the oily sludge, preventing the biomass from concentrating in a certain area, ensuring its full mixing with the oily sludge, creating good conditions for subsequent reactions, improving the co-treatment effect, and making the heat transfer and mass transfer processes between the biomass and the oily sludge more efficient, increasing the yield and quality of pyrolysis oil, and further making the substances collected after stratification purer, promoting the efficient resource utilization of the oily sludge.

[0048] Driven by the driving source 33, the inner arc groove 36 and the two-way slider 37 are used in conjunction to cause the cone 34 and the reverse rotor 312 to rotate in opposite directions to each other, breaking up the falling biomass while continuously and stably guiding the biomass, reducing the fluctuation of the treatment process caused by the uneven distribution of the biomass. The centrifugal force generated by the rotation of the reverse rotor 312 causes the biomass to diffuse to the surroundings, thereby expanding the distribution range of the biomass. The reverse rotation of the cone 34 further changes the movement trajectory of the biomass, so that biomass particles are dispersed inside and outside, increasing the dispersion degree of the biomass. The dual internal and external settings enable the biomass to be dispersed in a larger range in the collection bin 1, avoiding the aggregation of the biomass, creating favorable conditions for subsequent full mixing with the oily sludge, promoting the contact area between the two, and then reacting more fully in the subsequent treatment process.
