Description

Technical Field

[0001] The utility model belongs to the technical field of thermal cracking condensation, and in particular relates to thermal cracking oil and gas condensation equipment. Background Art

[0002] With my country's rapid economic development and the general improvement in people's living standards, cars have gradually become part of people's daily lives, generating a large amount of waste tires. The accumulation of these tires not only occupies land but is also highly susceptible to fires and environmental pollution. Recycling waste tires not only alleviates environmental pressures and reduces pollution, but also effectively recycles resources.

[0003] Current methods for treating scrap tires include prototype modification, production of recycled rubber and rubber powder, incineration, and pyrolysis. Pyrolysis technology holds great potential for treating scrap tires. Scrap tire pyrolysis involves thermally decomposing scrap tires in an oxygen-deficient or inert atmosphere, producing pyrolysis gas, pyrolysis oil, and charcoal residue. These products can be further processed and converted into high-value products with a variety of uses. Compared to traditional treatment methods, pyrolysis not only recovers high-value-added products but also recovers nearly 70% of energy, offering significant economic and environmental benefits. Pyrolysis technology, which produces gaseous, liquid, and solid products during incomplete thermal degradation, can completely pyrolyze scrap tires into useful products such as pyrolysis oil, pyrolysis carbon black, and pyrolysis non-condensable gases.

[0004] The pyrolysis oil produced by the above-mentioned thermal cracking process has high temperature characteristics and needs to be condensed before it can be further processed. However, existing condensing equipment still has problems such as low condensation efficiency and easy clogging when condensing pyrolysis oil. Utility Model Content

Based on the embodiments provided by the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0023] The utility model embodiment provides a thermal cracking oil and gas condensation device Figure 1 This is a schematic diagram of the structure of the thermal cracking oil and gas condensation equipment according to an embodiment of the present invention. Figure 1As shown, the thermal cracking oil and gas condensation equipment includes an oil-containing dust separation tower 1, a primary oil collector 2, a first-level cooling oil buffer tank 3, a first-level spray oil pool 4, and a first-level spray circulation tank horizontal condenser 5; the air inlet of the oil-containing dust separation tower 1 is arranged on the lower side of the oil-containing dust separation tower 1, the air outlet is arranged on the top of the oil-containing dust separation tower 1, the oil outlet is arranged on the lower side of the oil-containing dust separation tower 1, and a nozzle 15 is provided on the top of the oil-containing dust separation tower 1; the air inlet of the primary oil collector 2 is arranged on the lower side of the primary oil collector 2, the oil outlet is arranged at the bottom of the primary oil collector 2, and the air outlet is arranged on the upper side of the primary oil collector 2; the air inlet of the primary oil collector 2 The outlet is connected to the air outlet of the oil-containing dust separation tower 1, and a condensation array tube is provided in the middle of the primary oil collector 2. A nozzle 15 for spraying cooling medium to the condensation array tube is provided above and below the condensation array tube; the oil inlet of the first-level cooling oil buffer tank 3 is connected to the oil outlet of the oil-containing dust separation tower 1 and the oil outlet of the primary oil collector 2; the oil inlet of the first-level spray oil pool 4 is connected to the oil outlet of the first-level cooling oil buffer tank 3; the oil inlet of the first-level spray circulation tank horizontal condenser 5 is connected to the oil outlet of the first-level spray oil pool 4, and the oil outlet of the first-level spray circulation tank horizontal condenser 5 is connected to the nozzle 15 arranged in the oil-containing dust separation tower 1 and the primary oil collector 2 through a pipeline.

[0024] The above-mentioned thermal cracking oil and gas condensation equipment effectively removes dust and impurities in the circulating oil used for spraying by setting an oil-containing dust separation tower 1, a first-level cooling oil buffer tank 3, a first-level spray oil pool 4, and a first-level spray circulation tank horizontal condenser 5, thereby avoiding re-contamination of the oil product and reducing the occurrence of blockage problems. At the same time, by setting nozzles 15 for spraying cooling medium into the condensation tubes above and below the condensation tubes of the primary oil collector 2, combined with the circulating oil used for spraying being condensed in the first-level spray circulation tank horizontal condenser 5 and then sprayed, the condensation efficiency is guaranteed.

[0025] Specifically, the above-mentioned thermal cracking oil and gas condensation equipment has the following advantages:

[0026] 1) Improve condensation efficiency: The nozzle 15 sprays pyrolysis cycle oil to fully contact the rising gas, making it easier to liquefy the remaining condensable components in the first-stage condensation process, or effectively cool the non-condensable gas. This direct contact method improves the condensation efficiency and helps to more thoroughly recover valuable condensation products.

[0027] 2) Preventing blockage: The arrangement of the nozzle 15 in the primary oil collector 2 helps prevent blockage inside the condenser. Uniform spraying can avoid local overheating or accumulation of condensate, thereby reducing the risk of blockage, which is crucial for maintaining long-term stable operation of the condenser.

[0028] 3) Enhanced heat exchange: Spraying the condensation tubes in the primary oil collector 2 not only increases the contact area between the pyrolysis oil and the gas, but also further enhances the heat exchange effect through the falling film condensation formed during the spraying process. This heat exchange method helps to transfer heat more efficiently and improve the performance of the entire condensation system.

[0029] 4) Reduce energy consumption: By improving condensation efficiency and heat exchange effect, it helps to reduce the energy consumption of the entire thermal cracking process, which not only reduces energy consumption, but also helps to reduce production costs and improve economic benefits.

[0030] 5) Extend equipment life: It helps reduce scaling and clogging inside the condenser, thereby reducing equipment wear and corrosion, which helps extend the service life of the condenser and related equipment and reduce maintenance and replacement costs.

[0031] 6) Improve product quality: By more thoroughly recovering the condensed products, it helps to improve the purity and quality of the products, which is of great significance for the production of high-quality thermal cracking products.

[0032] In order to prevent the cooling oil from flowing back into the oil-containing dust separation tower 1 , the oil outlet of the oil-containing dust separation tower 1 is arranged below the air inlet of the oil-containing dust separation tower 1 .

[0033] In order to realize the timely transfer of the impurity slag separated in the oil-containing dust separation tower 1, a slag discharge port is opened at the bottom of the oil-containing dust separation tower 1, and a slag transfer vehicle connected to the slag discharge port is also included.

[0034] In order to further ensure the condensation effect, it also includes a secondary oil collector 6 and a tertiary oil collector 7; the air inlet of the secondary oil collector 6 is arranged on the lower side of the secondary oil collector 6, the oil outlet is arranged at the bottom of the secondary oil collector 6, and the air outlet is arranged on the upper side of the secondary oil collector 6; the air inlet of the secondary oil collector 6 is connected to the air outlet of the primary oil collector 2, and a condensation tube is provided in the middle of the secondary oil collector 6, and nozzles 15 for spraying cooling medium to the condensation tube are provided above and below the condensation tube; the air inlet of the tertiary oil collector 7 is arranged on the upper side of the tertiary oil collector 7, and the oil outlet is arranged at the bottom of the tertiary oil collector 7; the air inlet of the tertiary oil collector 7 is connected to the air outlet of the primary oil collector 2 and the secondary oil collector 6, and a condensation tube is provided in the middle of the tertiary oil collector 7, and nozzles 15 for spraying cooling medium to the condensation tube are provided above and below the condensation tube. It further includes a secondary cooling oil cache tank 8, a secondary spray oil pool 9, and a secondary spray system horizontal condenser 10; the oil inlet of the secondary cooling oil cache tank 8 is connected to the oil outlet of the secondary oil collector 6 and the oil outlet of the tertiary oil collector 7; the oil inlet of the secondary spray oil pool 9 is connected to the oil outlet of the secondary cooling oil cache tank 8; the oil inlet of the secondary spray system horizontal condenser 10 is connected to the oil outlet of the secondary spray oil pool 9, and the oil outlet of the secondary spray system horizontal condenser 10 is connected to the nozzle 15 provided in the secondary oil collector 6 and the tertiary oil collector 7 through a pipeline.

[0035] Furthermore, the oil inlet of the first-level spray oil pool 4 is connected to the lower side oil outlet of the first-level cooling oil cache tank 3, and the oil inlet of the second-level spray oil pool 9 is connected to the lower side oil outlet of the second-level cooling oil cache tank 8; the bottom oil outlet of the first-level cooling oil cache tank 3 and the bottom oil outlet of the second-level cooling oil cache tank 8 are connected to the cooling oil collection cache tank 11.

[0036] In some embodiments, the air inlet of the oil-dust separation tower 1 is connected to the rear steam-slag collection and separation bin 12 .

[0037] Regarding the oil-dust separation tower 1, specifically, after the waste tires are heated in the pyrolysis reactor, the high-temperature oil vapor and carbon residue are collected in the rear vapor-residue collection and separation chamber 12. A slag discharge port is located at the lower bottom of the chamber and connected to a slag conveyor to transport the carbon residue to the next process. A high-temperature oil vapor outlet is located at the upper right side of the chamber. A conveying pipeline transports the high-temperature oil vapor to the inlet of the oil-dust separation tower 1, where it is then transported for vapor and dust separation. The oil-dust separation tower 1 separates the incoming high-temperature oil vapor from the dust. The oil vapor within the tower rises from the bottom, while cooling oil sprayed downward from the top primarily separates the dust from the oil vapor, improving separation efficiency, product quality, and energy conservation. The inlet of the oil-dust separation tower 1 is located on the left side of the lower cone. It utilizes a countercurrent flow process, with high-temperature oil vapor entering through the lower cone and moving upward. A spray nozzle 15 is installed at the top of the tower 1 to spray and separate carbon black dust mixed with the high-temperature oil vapor, which then settles to the bottom of the tower along with the sprayed oil. The high-temperature oil vapor outlet is located vertically on the right side of the tower's upper end cap. The oil vapor is transported via an oil vapor pipeline to the lower primary oil collector 2 for treatment. The cooling oil outlet of the oil-dust separation tower 1 is located at the lower right corner of the cone at the bottom of the tower. To prevent cooling oil from entering the inlet, the edge of the cooling oil outlet is 10 mm lower than the inlet. A slag discharge valve is located at the bottom of the tower 1. Regularly discharged slag is directed to a slag transfer vehicle for external disposal. The high-temperature oil vapor after dust removal in the oil-containing dust separation tower 1 is transported through a pipeline to the primary oil collector 2 to recover the primary oil. The primary oil collector 2 has a built-in condensation tube.

[0038] In order to ensure the removal of impurities, a filter 13 is provided on the pipe connecting the oil inlet of the primary spray oil pool 4 and the oil outlet of the primary cooling oil buffer tank 3. A filter 13 is also provided on the pipe connecting the oil inlet of the secondary spray oil pool 9 and the oil outlet of the secondary cooling oil buffer tank 8.

[0039] In order to ensure the effective circulation of the circulating oil, a spray oil pump 14 is provided on the pipeline connecting the oil inlet of the horizontal condenser 5 of the first-level spray circulation tank and the oil outlet of the first-level spray oil pool 4, as well as on the pipeline connecting the oil inlet of the horizontal condenser 10 of the second-level spray system and the oil outlet of the second-level spray oil pool 9.

[0040] In the above thermal cracking oil and gas condensation equipment, the high-temperature oil vapor inlet of the primary oil collector 2 is arranged at the lower part of the left cylinder, and the oil vapor moves in reverse from the lower part to the upper part. The high-temperature oil vapor outlet of the primary oil collector 2 is arranged at the upper part of the right cylinder, and is sent to the next-step secondary oil collector 6 for treatment through a conveying pipeline. A lower nozzle 15 is arranged on the right side of the lower head of the primary oil collector 2, and an upper nozzle 15 is vertically arranged in the middle of the upper head of the primary oil collector 2. The upper and lower bidirectional spraying can effectively prevent the blockage of the cylinder and the condensation tubes. The primary oil collected by the oil-containing dust separation tower 1 and the primary oil collector 2 enters the primary cooling oil buffer tank 3 from the oil inlet of the primary spray circulation tank for circulation spraying. The circulating oil outlet of the primary cooling oil buffer tank 3 is arranged at the lower left part of the tank body, and is transported to the first-level spray oil pool 4 for buffering through a conveying pipeline. A filter 13 is arranged on the conveying pipeline. The oil inlet of the first-stage spray oil pool 4 is vertically arranged on the upper part of the tank body, and the circulating oil outlet is arranged on the lower left part of the tank body, and is connected to the oil inlet of the first-stage spray oil pump 14. The oil outlet of the first-stage spray oil pump 14 is connected to the oil inlet of the horizontal condenser, and the oil outlet of the horizontal condenser is connected to the first-stage spray system oil pipeline. The control valves configured on the pipeline are used to provide spray oil to the oil-containing dust separation tower 1 and the primary oil collector 2 respectively.

[0041] The oil vapor inlet of the secondary oil collector 6 is located on the left side of the lower head. The cylinder is built with condensation tubes. The oil vapor moves from the bottom to the upper part in the reverse direction. The oil vapor outlet is located on the upper right side of the upper head. The output oil vapor is further sent to the next step tertiary oil collector 7 for treatment. A lower nozzle 15 is set on the right side of the lower head of the secondary oil collector 6, and an upper nozzle 15 is vertically installed in the middle of the upper head. The oil spraying from top to bottom can prevent scaling and clogging on the inner wall of the cooling tube. The spray density is controlled by a control valve set on the delivery pipeline.

[0042] The oil vapor inlet of the tertiary oil collector 7 is set on the left side of the upper head, and the cylinder has a built-in condensation tube. After the incoming oil vapor is completely cooled, it falls from the top to the bottom and is cached in the secondary cooling oil buffer tank 8. An upper nozzle 15 is vertically set in the middle of the upper head of the tertiary oil collector 7, and a lower nozzle 15 is set in the lower head. The upper and lower spray heads spray oil to prevent the condensation tube from being blocked. The cooling oil and spray oil of the secondary oil collector 6 and the tertiary oil collector 7 fall into the secondary cooling oil buffer tank 8 for cache and standby through the oil drop port and the lower oil manifold set on the lower heads of the two devices. The cooling oil collected by the secondary cooling oil buffer tank 8 of the secondary oil collector 6 and the tertiary oil collector 7 for spraying overflows into the secondary spray oil pool 9 for storage, and a filter 13 is set on the overflow pipe. The oil inlet of the secondary spray oil reservoir 9 is vertically positioned at the top of the container, while the oil outlet is located at the bottom of the right cylinder, connecting to the oil inlet of the secondary spray pump. This inlet is then connected to the oil inlet of the horizontal condenser. The horizontal condenser's oil outlet supplies spray oil to the secondary oil collector 6 and the tertiary oil collector 7 via an oil pipeline, sharing a single secondary spray pump. The upper spray head of the secondary oil collector 6 is opened and flow controlled by a control valve, while the upper spray head of the tertiary oil collector 7 is opened and flow controlled by a control valve. The lower spray head 15 of the secondary oil collector 6 and the lower spray head 15 of the tertiary oil collector 7 are opened and flow controlled by a control valve. Control valves are also installed at the bottom of the primary cooling oil buffer tank 3 and the secondary cooling oil buffer tank 8 to control the oil level within the tanks. The collected cooling oil is then buffered in the cooling oil collection buffer tank 11.

[0043] The working process of the above-mentioned thermal cracking oil and gas condensation equipment is as follows:

[0044] High-temperature oil vapor enters the oil-containing dust separation tower 1 through the air inlet of the oil-containing dust separation tower 1, and the impurities are separated from the oil products and oil gas under the spraying of the spray liquid, wherein the oil gas is input into the primary oil collector 2 through the air outlet of the oil-containing dust separation tower 1 for further condensation, and the oil products are input into the primary cooling oil buffer tank 3 through the oil outlet of the oil-containing dust separation tower 1, and the oil and gas entering the primary oil collector 2 are further condensed through the condensation tubes, and are sprayed in two directions under the nozzles 15 arranged above and below, wherein the oil products are input into the primary cooling oil buffer tank 3 through the oil outlet of the primary oil collector 2, and the oil products in the primary cooling oil buffer tank 3 are precipitated and then enter the primary spray oil pool 4, and the oil products in the primary spray oil pool 4 enter the horizontal condenser 5 of the first spray circulation tank for further condensation to provide spray oil for the oil-containing dust separation tower 1 and the primary oil collector 2.
