Description

Technical Field

[0001] The invention relates to the field of organic waste treatment and utilization, and in particular to a static tar-removing sludge pyrolysis device. Background Art

[0002] Organic solid wastes such as sludge and oily sludge are large amounts of organic waste generated in production and life. They have complex compositions, usually high water content, high oil content and contain a large number of harmful components. They also have resource and environmental hazards. Therefore, it is necessary to develop efficient methods for the treatment and utilization of such solid wastes to achieve harmless treatment while effectively recovering the available resources in their components. Traditional methods mainly use incineration and sanitary landfill to dispose of organic solid wastes such as sludge and oily sludge. Their resource output rate is low and there is a risk of secondary pollution. The pyrolysis method heats the organic solid waste under anaerobic or anoxic conditions, and thermally decomposes its organic components, and then condenses the pyrolysis volatiles to finally obtain a condensable oil-water mixture, non-condensable gas and solid residue. Due to its many advantages such as high resource recovery rate, simple, efficient and thorough treatment, and less secondary pollution, it has gradually become the mainstream organic solid waste treatment technology today.

[0003] In the process of developing organic solid waste pyrolysis technology, the key is the development of stable and efficient pyrolysis equipment. For materials such as sludge and oil sludge that are highly viscous and easy to coke, it is very easy for such materials to coke and adhere to the wall of the pyrolysis device during the use of traditional rotary kiln or moving bed pyrolysis devices, thereby affecting the heat transfer efficiency of the pyrolysis device or the operation of the moving parts, and further leading to a decrease in the stability and efficiency of the pyrolysis device. In recent years, chain-plate pyrolysis devices have attracted widespread attention because the heating wall does not contact the material, is not easy to coke, and has high pyrolysis efficiency. At present, chain-plate pyrolysis devices mainly heat by radiation, and radiation heating is a surface heating method. If the material layer is too thick, the internal material cannot effectively receive the heat radiation, resulting in uneven heating of the material and coking. If the material layer is too thin, it will lead to a decrease in the disposal efficiency of the pyrolysis device and a decrease in the processing capacity. In addition, the chain plate pyrolysis mechanism is a key component in the chain plate pyrolysis device. However, the chain plates of the chain plate pyrolysis mechanism are easily loosened after expanding due to heat. The unstable operation of the chain plates also affects the overall operation effect of the chain plate pyrolysis device. Therefore, there is an urgent need to develop a more efficient sludge pyrolysis equipment. Summary of the Invention

[0022] Optionally, a slag discharge spiral is provided in the slag discharge port, and an expansion joint is further provided at the outlet end of the slag discharge port.

[0023] (3) Beneficial effects

[0024] When the static tar sludge pyrolysis device is performing pyrolysis treatment on the sludge, the material falls into the chain plate pyrolysis mechanism from the feed port, and the chain plate of the chain plate pyrolysis mechanism drives the material from the first end to the second end ( Figure 1 The material moves (from left to right in the center). During this movement, the material is continuously heated by the heating tubes above and below the chain plates. The static coke cleaning mechanism is stationary above and in contact with the chain plates, causing the sludge to be overturned by the static coke cleaning mechanism, exposing the internal sludge to heat radiation, thereby achieving uniform heating of the material. The organic components in the material decompose, and the volatiles produced by pyrolysis are discharged through the pyrolysis gas outlet on the right side of the furnace top. The pyrolyzed sludge and the sludge residue that falls to the furnace bottom are respectively transported by the chain plate pyrolysis mechanism and the furnace bottom slag cleaning mechanism to the slag discharge screw in the slag discharge port for discharge.

[0025] The above technical solution also has the following beneficial effects:

[0026] 1. The static coke cleaning mechanism's coke cleaning bracket and elastic mounting parts are ingeniously designed. The preload force set by the elastic mounting parts ensures close contact between the static coke cleaning mechanism and the chain plate pyrolysis mechanism. First, the elastic mounting parts tension the chain plates of the chain plate pyrolysis mechanism, ensuring that when the chain plates expand and loosen due to heat, they remain tensioned due to the spring tension. Second, the close contact between the coke cleaning bracket and the chain plates ensures that when oil sludge passes through the bracket, it is flipped out by the bracket's front guide plate and then flattened by the rear guide plate. This allows the material inside that has not been effectively heated to be flipped out and receive heat radiation, thereby achieving uniform heating of the material. Third, the close contact between the coke cleaning bracket and the chain plates scrapes the oil sludge, preventing the material from coking on the high-temperature chain plates. Fourth, the coke cleaning bracket fully utilizes the chain plate pyrolysis mechanism's own drive to perform coke cleaning, eliminating the need for a drive mechanism. This ensures strong operational stability and low processing and operating costs.

[0027] 2. The design of the furnace feed port has been improved. An arc-shaped guide plate and an insulation wall have been designed. The arc-shaped guide plate on the left side of the feed port can guide the sludge to generate a lateral velocity component to prevent the sludge from falling directly and impacting the chain plate pyrolysis mechanism. The insulation wall on the right side of the feed port prevents the heating pipe from heating the feed port, thereby preventing the sludge from heating up, decomposing, and coking at the feed port, ensuring stable feeding.

[0028] 3. The pyrolysis gas outlet has been optimized. An ash baffle is designed at the pyrolysis gas outlet to prevent fly ash generated during the discharging process of the pyrolysis-completed material from being discharged from the pyrolysis gas outlet.

[0029] 4. The ingenious design of the embedded slag discharge spiral saves the space of the slag discharge mechanism, making the device compact and occupying a small area.

[0030] 5. The above-mentioned device has an ingenious structural design, is simple and compact, easy to operate, stable in operation, convenient to clean and maintain, and has a high degree of automation, which can effectively ensure the efficient pyrolysis of organic solid waste that is prone to coking, such as oil sludge.

[0039] See also Figure 1 The present invention provides a static tar-removing sludge pyrolysis device, which includes a furnace body 1, a chain plate pyrolysis mechanism 2, multiple groups of heating tubes 3, multiple groups of static coke-removing mechanisms 4 and a furnace bottom slag-removing mechanism 5.

[0040] A furnace chamber is formed in the furnace body 1, and a feed port 11, a pyrolysis gas outlet 13 and a slag discharge port connected to the furnace chamber are also provided on the furnace body 1. The chain plate pyrolysis mechanism 2 is arranged in the furnace chamber, the feed port 11 is located above the first end of the chain plate pyrolysis mechanism 2, and the pyrolysis gas outlet 13 is located above the second end of the chain plate pyrolysis mechanism 2. Multiple groups of heating pipes 3 are spaced apart near the chain plate pyrolysis mechanism 2, and can be specifically distributed above the chain plate pyrolysis mechanism 2 and in the rotating cavity of the chain plate pyrolysis mechanism 2. The heating pipes 3 can be radiation heating pipes. Multiple groups of static coke cleaning mechanisms 4 are spaced apart along the transmission direction of the chain plate pyrolysis mechanism 2. The static coke cleaning mechanisms 4 all include an elastic mounting member 7 and a coke cleaning bracket. The upper end of the coke cleaning bracket is connected to the top surface of the furnace chamber through the elastic mounting member 7, and the lower end of the coke cleaning bracket abuts against the top surface of the chain plate pyrolysis mechanism 2. The furnace bottom slag cleaning mechanism 5 is arranged below the chain plate pyrolysis mechanism 2, and the slag discharge port is located below the second end of the furnace bottom slag cleaning mechanism 5. The furnace bottom slag cleaning mechanism 5 can push the slag on the furnace bottom into the slag discharge port. The furnace bottom slag cleaning mechanism 5 can be a slag scraping chain plate, and the slag scraping chain plate can be equipped with multiple scrapers or brushes for scraping the slag from the furnace bottom and transferring it to the slag discharge port.

[0041] When the static tar sludge pyrolysis device performs pyrolysis treatment on the sludge, the material falls into the chain plate pyrolysis mechanism 2 from the feed port 11, and the chain plate of the chain plate pyrolysis mechanism 2 drives the material from the first end to the second end ( Figure 1 The material moves from left to right in the middle (in the middle), and during the movement, the material is continuously heated by the heating tubes 3 above and below the chain plate, while the static coke cleaning mechanism 4 is statically arranged above the chain plate and in contact with the chain plate, so that the sludge is turned over by the static coke cleaning mechanism 4, and the internal sludge is exposed to receive heat radiation, thereby achieving uniform heating of the material. Moreover, multiple groups of static coke cleaning mechanisms 4 are spaced along the direction of material movement, and the material can be turned over multiple times to ensure the turning effect so that the material is fully heated. The organic components in the material decompose, and the volatiles produced by pyrolysis are discharged from the pyrolysis gas outlet 13 on the top right side of the furnace body 1. The sludge that has been pyrolyzed and the sludge residue that falls into the bottom of the furnace are respectively sent to the slag discharge port by the chain plate pyrolysis mechanism 2 and the furnace bottom slag cleaning mechanism 5 and discharged.

[0042] In a preferred embodiment, see Figure 2The coke cleaning bracket includes a front guide plate 41, a rear guide plate 42, a pair of end plates 43, a bottom plate 44 and a central axis 45 parallel to the bottom plate 44; wherein, the front guide plate 41 includes a plurality of mud scraping plates arranged at intervals, and the rear guide plate 42 includes a plurality of mud covering plates arranged at intervals, and the gaps between adjacent mud scraping plates and the gaps between adjacent mud covering plates are staggered with each other in sequence; the bottom ends of the front guide plates 41 and the bottom ends of the rear guide plates 42 are connected to the opposite sides of the bottom plate 44 in a one-to-one correspondence, and the bottom plate 44 extends along the transverse direction of the chain plate pyrolysis mechanism 2, and the opposite ends of the bottom plate 44 are respectively provided with end plates 43, and the top ends of the end plates 43 are connected to the central axis 45; the central axis 45 is connected to the elastic mounting member 7, and the bottom surface of the bottom plate 44 abuts against the top surface of the chain plate pyrolysis mechanism 2. Among them, the distance between the two end plates 43 can preferably be substantially equivalent to the width of the chain plate pyrolysis mechanism 2, so that the sludge near the edge of the chain plate pyrolysis mechanism 2 can also be overturned, thereby making the overturning effect more thorough.

[0043] In the above technical solution, the static coke cleaning mechanism 4 features a cleverly designed coke cleaning bracket and elastic mounting member 7. The preload applied by the elastic mounting member 7 ensures close contact between the static coke cleaning mechanism 4 and the chain plate pyrolysis mechanism 2. First, the elastic mounting member 7 tensions the chain plates of the chain plate pyrolysis mechanism 2, ensuring that the spring tension maintains the tension even when the chain plates expand and loosen due to heat. Second, the close contact between the coke cleaning bracket and the chain plates ensures that when oil sludge passes through the bracket, it is flipped out by the bracket's front guide plate 41 and then flattened by the rear guide plate 42. This allows any material inside that has not been effectively heated to be flipped out and exposed to heat radiation, thereby achieving uniform heating of the material. Third, the close contact between the coke cleaning bracket and the chain plates scrapes the oil sludge, preventing the material from coking on the high-temperature chain plates. Fourth, the coke cleaning bracket fully utilizes the chain plate pyrolysis mechanism 2's self-drive system for coke cleaning, eliminating the need for a drive mechanism. This results in strong operational stability and low processing and operating costs.

[0044] Among them, in a preferred embodiment, the angle between the bottom plate 44 and the front deflector 41 is 120° to 150°, preferably 135°; the angle between the bottom plate 44 and the rear deflector 42 is 120° to 150°, preferably 135°. Therefore, the front deflector 41 and the rear deflector 42 plus the bottom plate 44 together form a V-shaped groove. The V-shaped groove is formed according to Figure 1 In the configuration shown in FIG, the bottom plate 44 is placed flat on the top surface of the chain plate pyrolysis mechanism 2. The scraper plates on the left side of the V-shaped groove are staggered with the covering plates on the right side. That is, the scraper plates on the left side correspond to the gaps between the covering plates on the right side, and the gaps on the left side correspond to the covering plates on the right side. When processing sludge, the sludge follows the chain plate pyrolysis mechanism 2 and enters the gap on the left side of the V-shaped groove. However, it is blocked by the covering plate on the right side and can only move sideways to flow out of the gap on the right side, thereby re-settling the sludge.

[0045] The elastic mounting member 7 may include a plurality of springs arranged in parallel, each of which is pre-compressed between the top surface of the furnace and the central axis 45. The elastic mounting member 7 is provided with a pre-tightening force, so that the static coke cleaning mechanism 4 and the chain plate pyrolysis mechanism 2 can always maintain close contact.

[0046] Further, in a more preferred embodiment, see again Figure 1 The end of the feed port 11 located in the furnace is provided with an arc-shaped guide plate 111 and an insulation wall 112. The insulation wall 112 is located between the heating tube 3 and the feed port 11. The upper end of the arc-shaped guide plate 111 is connected to the edge of the feed port 11 and the lower end of the arc-shaped guide plate 111 extends obliquely toward the insulation wall 112. The above embodiment improves the design of the feed port 11 of the furnace body 1. The arc-shaped guide plate 111 on the left side of the feed port 11 can guide the oil sludge to generate a lateral component velocity, preventing the oil sludge from directly falling and impacting the chain plate pyrolysis mechanism 2. By designing the insulation wall 112 on the right side of the feed port 11, the heating tube 3 is prevented from heating the feed port 11, thereby preventing the oil sludge from heating up, decomposing, and coking at the feed port 11, thereby ensuring stable feeding.

[0047] In addition, an ash shield 131 is provided at one end of the pyrolysis gas outlet 13 located within the furnace. The angle between the ash shield 131 and the top surface of the furnace is 15° to 45°, preferably 30°. In the above embodiment, the pyrolysis gas outlet 13 is optimized. By designing the ash shield 131 at the pyrolysis gas outlet 13, fly ash generated during the discharge process of the pyrolyzed material is prevented from being discharged from the pyrolysis gas outlet 13.

[0048] In a preferred embodiment, see again Figure 1 The furnace body 1 includes a shell 14 forming a box-like structure, a steel structure bracket 15 disposed outside the shell 14, and a support base 16 disposed below the steel structure bracket 15. The steel structure bracket 15 is used to secure and support the shell 14, and the support base 16 is used to secure and support the steel structure bracket 15, thereby improving the overall strength of the furnace body 1. The shell 14 includes an outer steel shell, an inner steel shell, and an insulation layer disposed between the outer and inner steel shells, thereby improving the thermal insulation performance of the furnace body 1 and the overall thermal efficiency of the equipment. Inspection doors 12 are also provided on opposite sides of the furnace body 1. The inspection doors 12 are hinged to the furnace body 1 to facilitate maintenance of the equipment.

[0049] Furthermore, in a preferred embodiment, a slag discharge screw 6 is provided within the slag discharge port, and an expansion joint 61 is also provided at the outlet end of the slag discharge port for connection to subsequent slag processing equipment. The slag discharge screw 6 is embedded within the housing 14. The ingenious design of the embedded slag discharge screw 6 saves space in the slag discharge mechanism, making the device compact and occupying a small area.

[0050] The static tar-removing sludge pyrolysis device of the present invention has an ingenious structural design, is simple and compact, easy to operate, stable in operation, convenient to clean and maintain, and has a high degree of automation, and can effectively ensure the efficient pyrolysis of organic solid wastes that are prone to coking, such as oil sludge.
