Description

Technical Field

[0001] The utility model relates to the field of energy, in particular to a fully modularly assembled mid-stage feeding pyrolysis reactor. Background Art

[0002] Biomass pyrolysis refers to the thermochemical conversion technology method of heating biomass to 250-700°C in the absence of oxidants (air, oxygen, water vapor, etc.) or with limited oxygen, and decomposing biomass macromolecules (lignin, cellulose and hemicellulose) into smaller molecular fuel substances (solid charcoal, combustible gas, bio-oil) through thermochemical reactions. From the perspective of chemical reactions, complex thermochemical reactions occur in biomass during pyrolysis, including molecular bond breaking, isomerization and small molecule polymerization. (Zhao Tinglin, Wang Peng, Deng Dajun, et al. Current status and prospects of biomass pyrolysis research [J]. New Energy Industry, 2007, 5: 54-60).

[0003] The products of biomass pyrolysis are combustible pyrolysis gas and solid biochar, both of which are products that can be used for energy applications. In addition to being used as a heating fuel, gas can also be further reformed as a raw material for power generation and synthesis of green liquid fuels; in addition to being used as a fuel, biochar also has a lot of added value, and is also used as a fuel for metal smelting, food and light industry, a reducing agent for electric furnace smelting, and a covering agent to protect metals from oxidation during metal refining. In the chemical industry, it is often used as a raw material for carbon disulfide and activated carbon. The market for biochar is now vast.

[0004] Chinese patent CN201210590914.9 discloses a vertical pyrolysis reactor, which includes a reactor shell, a feeding device, a biomass gas outlet at the top of the reactor, an ash discharge device at the bottom of the reactor, and a grate inside the reactor. The feeding device is located at the bottom of the reactor, and the discharge port of the feeding device is located at the bottom center of the reactor.

[0005] Application number CN201220748018.6, patent name: A precise control vertical pyrolysis reactor, including a reactor shell, a feeding device, a biomass gas outlet at the top of the reactor, an ash discharge device at the bottom of the reactor, and a grate inside the reactor; the feeding device is located at the bottom of the reactor, and the discharge port of the feeding device is located at the bottom center of the reactor. The method of feeding at the bottom center solves the problem of uniform distribution among the three bottlenecks that have long plagued biomass pyrolysis reactors; a slag breaking device is installed in the pyrolysis reactor to form an organic combination with the rotating grate, and the running speed of the grate can accurately adjust the discharge amount, and precise pyrolysis reaction control is achieved by controlling the feeding speed, discharge speed, material layer thickness, air intake, air intake distribution, reaction temperature, etc. The ash discharge of the pyrolysis reactor is more stable and continuous, and the production reliability is greatly improved; the position design of the feeding device and the use of the slag breaking device can effectively and continuously process biomass up to about 10 cm in size.

[0006] However, the above-mentioned bottom-feed vertical pyrolysis reactor has technical problems of single fuel and small reactor capacity. Utility Model Content

[0007] In order to solve the technical problems of single fuel and small reactor capacity in the vertical pyrolysis reactor with bottom feeding in the prior art, the present application proposes a fully modularly assembled pyrolysis reactor with middle feeding, which solves the above technical problems.

[0008] The technical solution adopted by the utility model to solve its technical problems is:

A thermal valve; a modular lower shell, wherein the lower shell is detachably connected to the middle shell, a furnace plate is integrally integrated on the lower shell, the furnace plate is rotatably arranged inside the lower shell, a rotatable distributor is arranged on the top of the furnace plate, the distributor comprises a receiving tray and a material distribution tower with a pointed roof structure arranged at the center of the receiving tray, the material falling from the discharge port first falls to the pointed roof structure of the material distribution tower for primary distribution, the material after the primary distribution falls evenly to the outer circumference of the receiving tray for secondary distribution, and then falls more evenly onto the plate surface of the furnace plate.

[0010] Furthermore, the discharge port of the discharge pipe of the feeding device is arranged just above the distributor to evenly distribute the material, and is close to the distributor so that the discharge pipe can be inserted into the core feeding area and reaction area inside the pyrolysis reactor.

[0011] Furthermore, the discharge pipe is provided with an external insulation structure to isolate the temperature inside the pyrolysis reactor to prevent the temperature inside the discharge pipe from being too high, and the external insulation structure is an insulation layer, a water-cooled insulation device or an air-cooled insulation device.

[0012] Furthermore, the bottom of the terminal pipe of the discharge pipe of the feeding device protrudes so that the thermal insulation valve is closed in an inclined state on the discharge port. At the same time, the thermal insulation valve is rotatably arranged at the discharge port, and the rotating axis of the thermal insulation valve is arranged at the top of the terminal pipe of the discharge pipe.

[0013] Furthermore, the material distribution tower can be rotatably arranged on the supporting tray.

[0014] Furthermore, the material distribution tower is also provided with blades for extrapolating materials.

[0015] Furthermore, a seat body fixedly connected to the lower shell is arranged between the distributor and the furnace plate, and the outer circumference of the seat body wraps around the supporting tray upward to form an ash-proof cap.

[0016] Furthermore, the base body is connected to a plurality of fixed pipes, one end of the pipes is connected to the lower shell body, and the other end is connected to the base body. The pipes are arranged above the surface of the furnace plate to move the material on the surface of the furnace plate and play a role in stirring the material, which is conducive to accurately controlling the progress of the reaction.

[0017] Furthermore, the pipeline is a hollow structure, and circulating cooling water flows in the hollow structure.

[0018] Furthermore, an air inlet pipe is integrated on the furnace plate, and an air inlet of the air inlet pipe is formed at the bottom of the furnace plate.

[0019] Furthermore, it also includes a modular slag discharge seat that can be integrated with the lower shell body. The slag discharge seat can be detachably arranged at the bottom of the lower shell body. At the same time, a circular slag discharge port is formed at the bottom of the plate surface of the furnace plate and the inner wall of the lower shell body. The waste slag after the reaction is completed enters the slag discharge seat through the slag discharge port.

[0020] Furthermore, the corresponding connections of the upper shell, the middle shell, the lower shell and the slag discharge seat are all ring-matched to achieve modular assembly that can be adjusted in any direction in the horizontal direction.

[0021] Based on the above technical solution, the technical effects that can be achieved by the utility model are:

[0022] The utility model is a fully modularly assembled pyrolysis reactor with middle-stage feeding. At least two feeding devices are arranged on the middle shell, and two materials can be input at the same time. The feeding amount and the capacity of the reactor can be made relatively large, which is about 4-10 times the capacity of the lower feeding reactor. The requirements for the particle size of the material are relatively low, the requirements for the fineness of the material itself are low, and the processing capacity is greater. The discharge port of the discharge pipe is equipped with an insulation valve that can be automatically closed under the action of gravity. One disadvantage of upper feeding is that hot air will enter the feeding device from the discharge pipeline and affect the material without backflow. The corresponding material and hot gas collection amount, and the automatically closed insulation valve can ensure the material of the feeding device and prevent the loss of hot gas. Compared with the traditional direct feeding at the top of the reactor, the pyrolysis reactor of the utility model is actually fed in the middle section of the reactor, and the gas collection pipeline is arranged at the top of the reactor. The rising hot gas can more easily enter the gas collection pipeline. At the same time, the discharge port of the discharge pipe is arranged in the middle section, the falling height of the material is reduced, and the falling trajectory of the material can be effectively controlled. Furthermore, a rotatable distributor is arranged on the top of the lower shell, and the distributor includes a support The tray and the material distribution tower with a pointed roof structure arranged in the center of the tray, the materials falling from the discharge port first fall to the pointed roof structure of the material distribution tower for primary distribution, and the materials after the primary distribution fall evenly to the outer circumference of the tray for secondary distribution, and then fall more evenly to the plate surface of the furnace plate, so that the reaction control of the materials is more accurate. On the other hand, the fully modularly assembled mid-section feeding pyrolysis reactor of the utility model can be manufactured in a modular manner, and can be pre-installed by professional technicians in the workshop of the reactor manufacturer, including electrical and monitoring systems, and comprehensive cold and hot debugging, and then modularly transported to the site, avoiding rough installation by non-professional construction personnel at the work site, shortening the on-site installation time by 90% and ensuring the installation quality. The modular installation also ensures that the angles of feeding, air intake, charcoal discharge, air outlet, etc. can be adjusted at any time. Under the standardization of various modular equipment, each installation angle can be adjusted like a combination of building blocks to suit the on-site needs of customers, without changing the overall design of the pyrolyzer. In short, the modular design maximizes the commercialization level and also realizes the precise control of the pyrolysis reaction.

[0023] The utility model discloses a fully modularly assembled mid-section feeding pyrolysis reactor, wherein the corresponding connections of the upper shell, the middle shell, the lower shell and the slag discharge seat of the pyrolysis reactor are all ring-matched, so as to realize modular assembly in any direction in the horizontal direction.

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0032] like Figure 1-2As shown, the utility model provides a fully modularly assembled mid-stage feeding pyrolysis reactor, comprising a modular upper shell 1, a modular middle shell 2 and a modular lower shell 3, the upper shell 1 is provided with a gas collecting pipeline 11 to collect the required gas after the reaction, the middle shell 2 is detachably connected to the upper shell 1, at least two feeding devices 21 are provided on the middle shell 2, and the main material and the auxiliary material can be fed at the same time, the discharge pipe 211 of the feeding device 21 is inserted into the interior of the middle shell 2, and the discharge port of the discharge pipe 211 is provided with an insulation valve 212 that can be automatically closed under the action of gravity to prevent the furnace from The hot gas backflow feeding device, the lower shell body 3 is detachably connected to the middle shell body 2, the lower shell body 3 is integrally integrated with a furnace plate 31, the furnace plate 31 is rotatably arranged inside the lower shell body 3, and the top of the furnace plate 31 is provided with a rotatable distributor 32, the distributor 32 includes a receiving tray 321 and a material distribution tower 322 with a pointed roof structure arranged at the center of the receiving tray 321, the material falling from the discharge port first falls to the pointed roof structure of the material distribution tower 322 for primary distribution, and the material after the primary distribution evenly falls to the outer circumference of the receiving tray 321 for secondary distribution, and then falls more evenly onto the disk surface of the furnace plate 31.

[0033] The utility model is a fully modularly assembled mid-section feeding pyrolysis reactor, and at least two feeding devices 21 are arranged on the middle shell 2, which can input at least two materials at the same time. In a certain pyrolysis environment, multiple feeds are necessary, such as pyrolysis of low calorific value dried sludge. When the sludge calorific value is too low and the pyrolysis reaction may be interrupted, the immediate input of sawdust with a relatively high calorific value can ensure the progress of the reaction and the stability of the pyrolysis gas; moreover, it can be realized immediately. If it is the same feed port, it is necessary to change the material outside the reactor and before the discharge port, and the labor cost and the degree of automation are low, and it is difficult to ensure the pyrolysis quality. For example, some special solid wastes (such as RDF or plastic film, etc.) have their own special input methods, and require their own unique discharge pipe 211 feeding system.

[0034] The fully modularly assembled pyrolysis reactor of the utility model with middle-stage feeding can have a relatively large feed volume and reactor capacity, which is about 4-10 times the capacity of the lower-feed reactor. The requirements for the particle size of the material are relatively low, the requirements for the fineness of the material itself are low, and the processing capacity is also greater. The discharge port of the discharge pipe 211 is equipped with an insulation valve 212 that can be automatically closed under the action of gravity. One disadvantage of upper feeding is that hot gas will enter the feeding device 21 from the discharge pipe 211, affecting the material that does not need to react and the gas collection amount of hot gas, and the automatically closed insulation valve 212 It is possible to ensure the material of the feeding device 21 and prevent the loss of hot gas. Compared with the traditional method of directly feeding at the top of the reactor, the pyrolysis reactor of the utility model is actually located in the middle section of the reactor, close to the core reaction zone, and does not interfere with the composition and output of the pyrolysis gas products. The gas collecting pipe 11 is arranged at the top of the reactor, and the rising hot gas can more easily enter the gas collecting pipe 11. At the same time, the discharge port of the discharge pipe 211 is arranged in the middle section, and the falling height of the material is reduced, which can effectively control the falling trajectory of the material. Furthermore, a rotatable distributor 32 is arranged on the top of the lower shell 3, and the distributor 32 includes The receiving tray 321 and the material distribution tower 322 with a pointed roof structure arranged in the center of the receiving tray 321 are included. The materials falling from the discharge port first fall to the pointed roof structure of the material distribution tower 322 for primary distribution. The materials after the primary distribution evenly fall to the outer circumference of the receiving tray 321 for secondary distribution, and then fall more evenly on the plate surface of the furnace plate 31, so that the reaction control of the materials is more accurate. On the other hand, the fully modular assembled mid-stage feeding pyrolysis reactor of the utility model can be manufactured in a modular manner, and professional technicians can pre-install electrical and monitoring systems in the workshop of the reactor manufacturer. The system is equipped with a complete cold and hot commissioning system, and then transported to the site in modular form, avoiding rough installation by non-professional construction workers on the job site, shortening the on-site installation time by 90% while ensuring the installation quality. The modular installation also ensures that the angles of feed, air intake, charcoal discharge, and air outlet can be adjusted at any time. When each modular equipment is standardized, the installation angles can be adjusted like combining building blocks to suit the customer's on-site needs, without having to change the overall design of the pyrolyzer. In short, the modular design not only maximizes the commercialization level, but also realizes the precise control of the pyrolysis reaction.

[0035] In a further preferred embodiment of the present invention, a discharge port of a discharge pipe 211 of a feeding device 21 is arranged above and close to a distributor 32. The pyrolysis reactor of the present invention is different from a conventional reactor (such as a vertical kiln). In fact, the feed is fed from the middle section. The discharge pipe 211 of the feeding device 21 extends directly to the core area of ​​the pyrolysis reactor. The height above the distributor 32 on the top of the furnace plate 31 is less than 1 meter. The upper space of the discharge pipe 211 in the pyrolysis reactor is 4-8 meters high. Conventional reactors scatter materials from the highest point, the 8-meter-high furnace top. In this way, it is difficult to ensure that the materials are evenly scattered on the surface of the furnace plate 31. All feeding devices 21 are equivalent to sending materials directly to the upper part of the reaction core area, which does not affect the gas reaction above, but can ensure that the materials are stably and accurately sent to the top of the furnace plate 31, ensuring that the materials fall on the distributor 32 on the furnace plate 31, and the distributor 32 ensures that the materials are evenly sprinkled on the surface of the furnace plate 31. Evenly spreading the material on the surface of the furnace plate 31 is a necessary guarantee for accurate control of the pyrolysis reaction. Different material levels on the surface of the furnace plate 31 mean that there may be local high temperatures and burn-through, which makes it difficult to ensure accurate control, the stability of the pyrolysis gas product, and the production of other biomass high-quality synthesis gas components using pyrolysis gas.

[0036] In a preferred embodiment of the present invention, an external insulation structure is arranged on the discharge pipe 211 to isolate the temperature inside the pyrolysis reactor to prevent the temperature inside the discharge pipe 211 from being too high. The external insulation structure is an insulation layer, a water-cooled insulation device or an air-cooled insulation device.

[0037] In a preferred embodiment of the utility model, the bottom of the water-cooling pipe 34 at the end of the discharge pipe 211 of the feeding device 21 protrudes so that the insulation valve 212 is closed on the discharge port in an inclined state. At the same time, the insulation valve 212 is rotatably arranged at the discharge port, and the rotation axis of the insulation valve 212 is arranged at the top of the water-cooling pipe 34 at the end of the discharge pipe 211. On the one hand, the resistance of the material pushing the insulation valve 212 is reduced, and on the other hand, it can ensure that the insulation valve 212 can be automatically closed under the action of gravity. Further, the center of gravity of the insulation valve 212 is moved downward to ensure the stability of its automatic closing function. The method of moving the center of gravity downward can be to configure a counterweight block at the bottom of the insulation valve 212 or to make the bottom of the insulation valve 212 thicker.

[0038] In a preferred embodiment of the present invention, the portion of the discharge pipe 211 inserted into the furnace body is provided with a heat-insulating layer for heat preservation and insulation.

[0039] In a preferred embodiment of the present invention, the material distribution tower 322 is rotatably disposed on the receiving tray 321 to achieve a better and more uniform distribution of materials and to push the materials on the receiving tray 321 onto the furnace plate 31 .

[0040] Furthermore, the material distribution tower 322 is also provided with blades 323 for pushing materials outward.

[0041] In a preferred embodiment of the present invention, a seat body 33 fixedly connected to the lower shell 3 is arranged between the distributor 32 and the furnace plate 31, and the outer circumference of the seat body 33 wraps upwardly around the support tray 321 to form an anti-ash cap 331 to reduce the entry of dust into the shaft and motor at the furnace plate 31.

[0042] In a preferred embodiment of the present utility model, the base body 33 is connected to a plurality of fixed water-cooling pipes 34, one end of the water-cooling pipes 34 is connected to the lower shell body 3, and the other end is connected to the base body 33. The water-cooling pipes 34 are arranged above the surface of the furnace plate 31 to move the material on the surface of the furnace plate 31 to prevent the material from being arched or hardened on the surface of the furnace plate 31.

[0043] In a preferred embodiment of the present invention, the water-cooling pipe 34 is a hollow structure, and circulating cooling water flows in the hollow structure to achieve cooling, while also assisting in the precise regulation of the temperature in the furnace.

[0044] In a preferred embodiment of the present invention, an air inlet duct 35 is integrated on the stove plate 31, and the air inlet of the air inlet duct 35 is formed at the bottom of the stove plate 31, which is a manifestation of the integrated modularization of the lower shell 3 and the stove plate 31 on the lower shell 3 of the present invention.

[0045] In a preferred embodiment of the present invention, a modular slag discharge seat 4 which can be integrated with the lower shell 3 is also included. The slag discharge seat 4 can be detachably arranged at the bottom of the lower shell 3. At the same time, a round slag discharge port 36 is formed at the bottom of the plate surface of the furnace plate 31 and the inner wall of the lower shell 3. The waste slag after the reaction is completed enters the slag discharge seat 4 through the slag discharge port 36. This is also a manifestation of the complete modularization of the pyrolysis reactor of the present invention. Each part can be pre-selected and completely installed by professionals in the workshop. For example, electrical and monitoring can be installed in the workshop. Now only non-professionals need to perform simple assembly, which can save 90% of the installation time and ensure the installation quality.

[0046] In a specific embodiment of the utility model, the corresponding connections of the upper shell 1, the middle shell 2, the lower shell 3 and the slag seat 4 of the pyrolysis reactor of the utility model are all ring-matched to achieve modular assembly that can be adjusted in any direction in the horizontal direction. The lower shell 3 is provided with a manhole 37, and the directions of its main modular split equipment can be arbitrarily combined like building blocks to meet various customer usage requirements. For example, the orientations of the feeding device 21, the manhole 37, the gas collection pipe 11 and the slag seat 4 can be changed at will without changing the overall design of the pyrolysis reactor itself. This design can greatly shorten the time for customer customized products.

[0047] It should be understood that the specific embodiments described above are only used to explain the present invention, and are not used to limit the present invention. Obvious changes or modifications derived from the spirit of the present invention are still within the scope of protection of the present invention.
