Description

Technical Field

[0001] This application relates to the field of waste treatment technology, and in particular to a sludge co-processing system for pyrolysis and gasification of general industrial solid waste. Background Technology

[0002] As is well known, pyrolysis gasification furnaces are used for the pyrolysis incineration of municipal solid waste and are widely used in waste treatment. They have good performance. With the continuous development of society, the amount of municipal solid waste generated is gradually increasing, and therefore the demand for pyrolysis gasification furnaces is also gradually increasing. Waste pyrolysis gasification refers to the process in which large organic molecules in waste break down under anaerobic or hypoxic conditions, producing small molecule gases, tar, and residues. Waste pyrolysis gasification technology not only achieves the harmlessness, reduction, and resource recovery of waste, but also effectively overcomes the dioxin pollution problem caused by waste incineration. Therefore, it has become a waste treatment technology with great development prospects.

[0003] Currently, in the relevant technologies, a search reveals that the utility model with patent publication number CN222164811U discloses a comprehensive system for sludge co-processing with general industrial solid waste pyrolysis and gasification, including: a support frame, and also including: a furnace body, which is fixedly embedded in the inner wall of the support frame near the top, a filter plate is fixedly embedded in the inner wall of the furnace body near the bottom, and a tripod mounting bracket is fixedly embedded in the inner wall of the furnace body near the top.

[0004] Regarding the aforementioned technologies, although the combination of components such as stirring rods and scrapers can improve the mixing and combustion effects of materials to a certain extent, the applicant has found that their mixing structures mostly adopt a single rotating rod and stirring rod design, with relatively fixed mixing parameters. During the mixing process, this single mixing structure is difficult to adapt to the characteristics of complex materials. For sludge with high moisture content, it is easy to stick to the stirring rod and furnace wall, resulting in insufficient mixing. Some sludge is difficult to mix effectively with industrial solid waste. This uneven mixing will cause uneven heating of the material during pyrolysis and gasification, with incomplete pyrolysis in some areas, producing a large amount of residue, reducing the waste conversion rate and energy recovery efficiency, and thus having certain limitations in application.

[0005] Therefore, we propose a sludge-co-processed integrated system for the pyrolysis and gasification of general industrial solid waste. Utility Model Content

[0006] The purpose of this invention is to provide a comprehensive system for the pyrolysis and gasification of sludge and general industrial solid waste, in order to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A combined system for sludge co-processing and general industrial solid waste pyrolysis and gasification includes:

[0009] The pyrolysis furnace body has a discharge port at one end;

[0010] The drive motor is detachably connected to the pyrolysis furnace body via two mounting bases, and the output shaft of the drive motor is provided with a connecting shaft, which extends into the pyrolysis furnace body via a rotary sealing ring;

[0011] A connecting plate is detachably connected to a connecting shaft. Two stirring columns are fixedly connected to the bottom of the connecting plate, and multiple stirring blades are provided on the outer wall of the stirring columns.

[0012] The collection bin is slidably mounted inside the pyrolysis furnace body and is used to collect the pyrolysis material.

[0013] Two exhaust pipes are connected to the main body of the pyrolysis furnace, and the other end of the exhaust pipe is connected to a filter chamber, on which an exhaust head is provided;

[0014] A support assembly is disposed at the bottom of the pyrolysis furnace body and is used to support the pyrolysis furnace body in its place of use.

[0015] As a further embodiment of this utility model: the support assembly includes four support columns, all of which are symmetrically arranged at the bottom of the pyrolysis furnace body, and the other end of each support column is fixedly connected to a support base.

[0016] As a further improvement of this utility model, the bottom of each of the multiple support seats is provided with an anti-slip rubber pad.

[0017] As a further embodiment of this utility model: one end of the pyrolysis furnace body is detachably connected to an mounting plate by multiple mounting bolts, an L-shaped support is fixedly connected to the mounting plate, the other end of the L-shaped support is fixedly connected to a support, and the filter chamber is detachably connected to the support.

[0018] As a further improvement of this utility model, the collection chamber is provided with a strip handle.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] By setting up a support assembly, the main body of the pyrolysis furnace is supported and placed in the usage position with the cooperation of multiple support columns and support seats. Then, the connecting shaft is driven by the drive motor to rotate, and the two stirring columns under the connecting plate rotate synchronously. Multiple stirring blades on the outer wall form a multi-dimensional stirring force on the material, which can break the sticky state of sludge with high water content, promote the full mixing of sludge and general industrial solid waste, and avoid incomplete local pyrolysis. The exhaust gas generated by pyrolysis is introduced into the filter chamber through the exhaust pipe for purification and then discharged from the exhaust head, reducing air pollution. The sliding clamping design of the collection bin and the strip handle facilitate the quick cleaning of residues after pyrolysis. Its overall structure is relatively simple. Compared with the existing technology, it has significant advantages such as high-efficiency mixing, stable positioning, environmentally friendly exhaust and convenient maintenance, thereby improving the co-treatment effect of sludge and industrial solid waste. It has strong comprehensive practicality and is conducive to promotion and use. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] The present application will be further described in detail below with reference to the accompanying drawings.

[0028] Please see Figures 1-4In this embodiment of the present invention, a sludge co-processing and general industrial solid waste pyrolysis and gasification integrated system includes:

[0029] The pyrolysis furnace body 1 has a discharge port at one end;

[0030] The drive motor 2 is detachably connected to the pyrolysis furnace body 1 via two mounting bases 3, and the output shaft of the drive motor 2 is provided with a connecting shaft 4, which extends into the pyrolysis furnace body 1 via a rotary sealing ring 5.

[0031] The connecting plate 6 is detachably connected to the connecting shaft 4. Two stirring columns 7 are fixedly connected to the bottom of the connecting plate 6, and multiple stirring blades 8 are provided on the outer wall of the stirring columns 7.

[0032] Collection bin 9 is slidably mounted inside the pyrolysis furnace body 1 and is used to collect the pyrolysis material.

[0033] Two exhaust pipes 10 are connected to the pyrolysis furnace body 1, and the other end of the exhaust pipe 10 is connected to a filter chamber 11, on which an exhaust head 12 is provided.

[0034] A support assembly is provided at the bottom of the pyrolysis furnace body 1, which is used to support the pyrolysis furnace body 1 in the position of use.

[0035] This integrated sludge and general industrial solid waste pyrolysis and gasification system operates by using a support assembly to ensure stable placement of the equipment. Sludge and general industrial solid waste are fed into the furnace through the discharge port at one end of the pyrolysis furnace body 1. The drive motor 2, fixed by the mounting base 3, is then started. The output shaft of the drive motor 2 drives the connecting shaft 4 to rotate. The rotating sealing ring 5 ensures the sealing of the connecting shaft 4 during rotation. The connecting shaft 4 drives two stirring columns 7 to rotate synchronously through the connecting plate 6. Multiple stirring blades 8 on the outer wall of the stirring column 7 create multi-dimensional stirring force on the materials in the furnace, breaking the sludge adhesion and promoting thorough mixing of sludge and industrial solid waste. During pyrolysis, the generated waste gas is introduced into the filter chamber 11 through two exhaust pipes 10. The purified gas is discharged from the exhaust head 12. After pyrolysis is completed, the operator holds the strip handle 20 on the collection chamber 9 and pulls out the collection chamber 9, which is slidably clamped in the furnace, to clean the pyrolysis residue.

[0036] exist Figure 1-3 The support assembly includes four support columns 13, which are symmetrically arranged at the bottom of the pyrolysis furnace body 1. The other end of each support column 13 is fixedly connected to a support base 14, and the bottom of each support base 14 is provided with an anti-slip pad 15.

[0037] This integrated sludge-gasification system for general industrial solid waste pyrolysis utilizes a structure where four symmetrically distributed support columns 13 provide balanced and stable support for the pyrolysis furnace body 1, stabilizing the body off the ground and preventing wear or corrosion caused by direct contact between the bottom of the pyrolysis furnace and the ground. The support base 14 increases the contact area with the ground, and the anti-slip rubber pads 15 at the bottom further enhance friction, effectively offsetting the vibration and impact forces generated by stirring during pyrolysis, preventing equipment displacement, ensuring the stability of the mixing of sludge and industrial solid waste by the stirring blades 8, and improving the overall safety of the equipment placement, thus adapting to the needs of long-term continuous operation.

[0038] exist Figure 1-4 In the pyrolysis furnace body 1, one end is detachably connected to a mounting plate 17 via multiple mounting bolts 16. An L-shaped support column 18 is fixedly connected to the mounting plate 17, and a support 19 is fixedly connected to the other end of the L-shaped support column 18. A filter chamber 11 is detachably connected to the support 19. A strip handle 20 is provided on the collection chamber 9. The mounting bolts 16 facilitate the easy assembly and disassembly of the mounting plate 17 from the pyrolysis furnace body 1. The L-shaped support column and the support 19 cooperate to provide stable support for the filter chamber 11, ensuring the airtight connection between the filter chamber 11 and the exhaust pipe 10, and ensuring the efficient introduction and purification of pyrolysis waste gas. The detachable design of the filter chamber 11 facilitates the periodic removal for cleaning or replacement of internal filter components, reducing maintenance difficulty. The strip handle 20 on the collection chamber 9 provides a convenient point of force for cleaning residues after pyrolysis, allowing operators to quickly remove the collection chamber 9 to handle waste materials, reducing downtime.

[0039] In this embodiment, both the pyrolysis furnace body 1 and the drive motor 2 are commercially available devices known to those skilled in the art. They can be customized or selected according to actual needs. Here, we are simply using them without making any structural or functional improvements, so we will not go into detail here. Both the pyrolysis furnace body 1 and the drive motor 2 are equipped with matching control switches. The installation position of the control switches is selected according to actual usage needs to facilitate operation and control by the operator. The technology is already very mature and can be implemented.

[0040] The implementation principle of the sludge co-processing general industrial solid waste pyrolysis gasification integrated system in this application embodiment is as follows: First, the pyrolysis furnace body 1 is stably erected off the ground by the cooperation of multiple support columns 13 and multiple support seats 14. The operator feeds the sludge to be treated and general industrial solid waste into the pyrolysis furnace body 1 in proportion through the discharge port at one end of the pyrolysis furnace body 1. Then, the drive motor 2, which is detachably fixed by two mounting seats 3, is started. The output shaft of the drive motor 2 drives the connecting shaft 4 to rotate. The rotating sealing ring 5 ensures the sealing of the inside of the pyrolysis furnace body 1 when the connecting shaft 4 rotates. The connecting shaft 4 drives the two stirring columns 7 at the bottom to rotate synchronously through the detachably connected connecting plate 6. The multiple stirring blades 8 on the outer wall of the stirring column 7 affect the furnace. The internal materials form a multi-dimensional stirring force, breaking the sticky state of the sludge with high water content, and promoting the sludge to be fully and evenly mixed with general industrial solid waste, laying the foundation for subsequent efficient pyrolysis and gasification. During the pyrolysis process, the generated waste gas is introduced into the filter chamber 11 through two exhaust pipes 10. The filtered and purified gas is discharged from the exhaust head 12, reducing pollution to the atmospheric environment. After the pyrolysis is completed, the operator holds the strip handle 20 on the collection chamber 9 and pulls out the collection chamber 9 that is slidably locked in the pyrolysis furnace body 1 to clean the residue after pyrolysis. If the filter chamber 11 needs to be maintained, the mounting bolt 16 at one end of the pyrolysis furnace body 1 can be removed, the mounting plate 17 and the L-shaped support column and support 19 fixed thereto can be removed, and then the filter chamber 11 can be removed for inspection or replacement.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
