Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of gas producer, especially to a cross partition wall type rotating bed gasification furnace. BACKGROUND

[0002] The existing cross partition wall type rotating bed gasification furnace includes a dry distillation section with a cross partition wall, a furnace body, and a slag discharge system, the dry distillation section is divided into four feeding cavities, the dry distillation section is arranged above the furnace body and connected with the furnace body, the slag discharge system is connected with the bottom of the furnace body, the slag discharge system includes an ash tray and a tower type furnace grate, the ash tray is connected with the tower type furnace grate, the furnace body is partially arranged in the ash tray, the ash tray can rotate around the furnace body, the outer wall of the furnace body is connected with a support arm, a slide rail and a hydraulic drive device are arranged below the ash tray, and the slide rail is connected with a base. After a long time, the concrete base will settle, and mechanical wear, slag accumulation in the furnace, and excessive accumulation of ash and slag will cause the ash tray to tilt and rotate abnormally, which will affect the production efficiency. Although the producer will arrange regular maintenance, due to the large volume of the rotating bed gasification furnace and the slow rotation speed of the ash tray, complex detection is required to determine whether the ash tray and the furnace body are tilted, and the production personnel cannot discover the problem in time. When the problem is discovered, it may greatly affect the production efficiency. In addition, the furnace body of the existing cross partition wall type rotating bed gasification furnace is integrated and made of a steel water jacket. The temperature in different areas of the furnace body is different, which causes the pressure of the water in the steel water jacket to be different. The integrated water jacket as the furnace body makes the thickness of the water jacket in the low-pressure area of the furnace body the same as that in the high-pressure area, which wastes resources. Furthermore, the existing cross partition wall type rotating bed gasification furnace with a diameter of more than 4.3 meters needs to be provided with more than 8 fire detection holes on the side wall of the furnace body, which needs to be operated multiple times to uniformly detect the combustion of coal particles in the furnace body. This also easily causes problems in the gas seal. Once the gas seal is damaged, the gas in the furnace may leak. SUMMARY

[0003] The utility model aims at providing a cross partition wall type rotating bed gasification furnace to solve one or more technical problems in the prior art and at least provide a beneficial choice or create conditions.

[0004] To solve the above technical problems, the utility model adopts the following technical solutions:

[0005] First, the utility model provides a kind of cross partition wall formula rotary bed gasifier, including furnace body, ash tray, dry distillation section, be located the tower type furnace grate in the bottom of the furnace body, the furnace body top is connected the dry distillation section, the furnace body bottom is located in the ash tray partially and the ash tray rotates around the furnace body, the ash tray is connected with the tower type furnace grate, the furnace body includes first water jacket, second water jacket, the second water jacket is located the first water jacket top, the second water jacket is connected with the first water jacket, the second water jacket is connected with the dry distillation section, two fire observation ports are symmetrically provided on the second water jacket, the fire observation port includes first fire hole and second fire hole, the first fire hole is located the top of the second water jacket, and extends to the inside of the second water jacket, the second fire hole is located the sidewall of the upper portion of the second water jacket, the axis of the first fire hole points to the sidewall of the tower type furnace grate, and the axis of the second fire hole points to the top of the tower type furnace grate.

[0006] By setting the second water jacket and the first water jacket into the furnace body, the furnace body can be divided into two components for production and reassembly. When producing the furnace body, it is not necessary to form the furnace body integrally, which can reduce the processing size of the furnace body and the production difficulty. Secondly, the furnace body is composed of the first water jacket and the second water jacket, which can produce water jackets with different thicknesses for different temperature regions inside the furnace body. It is not necessary to use steel materials with the same thickness to manufacture the water jackets of the furnace body, which is beneficial to save costs and reduce resource consumption. Of course, although using steel materials with the same thickness to produce the furnace body cannot save energy consumption, it can still achieve the purpose of reducing manufacturing difficulty. In addition, the first fire hole is arranged on the top of the second water jacket, and the second fire hole is arranged on the upper sidewall of the second water jacket, which is more convenient for observing the combustion of coal particles inside the furnace body. When using a drill rod to observe fire, the combustion of coal particles at the top and the bottom of the tower type furnace grate can be detected simultaneously. Since the cross partition wall formula rotary bed gasifier has four feeding cavities, the two fire observation ports are symmetrically arranged relative to the axis of the furnace body, which can detect the combustion of coal particles falling into the feeding cavities during the rotation of the tower type furnace grate with fewer times, which can save manpower and reduce the probability of gas seal failure.

[0007] As an extension of the above scheme, a cross partition wall formula rotary bed gasifier further includes: a first detection device, the first detection device includes a base, a first support, a sliding wheel seat, the first support includes a first connecting arm and a second connecting arm, the first connecting arm is connected with the base, the second connecting arm is connected with the sliding wheel seat, the first connecting arm and the second connecting arm are connected through an elastic locking mechanism, the base is connected with the top of the ash tray, a roller is arranged on the sliding wheel seat, and the roller abuts against the furnace body.

[0008] By setting the first detection device on the upper part of the ash tray, it can be quickly judged whether there is a lateral inclination between the ash tray and the furnace body by observing the distance between the sliding wheel seat and the furnace body when the ash tray rotates around the furnace body.

[0009] Specifically, in the initial installation state, by adjusting the first support, the rotating roller on the sliding wheel seat abuts against the furnace body, and when the ash tray rotates around the furnace body, the roller follows the outer wall of the furnace body. When there is a lateral inclination between the ash tray and the furnace body due to various conditions, the rotation track of the ash tray will change, causing the roller to move closer to the furnace body in the local area during the following process, so that the roller and the furnace body will have an action force that will cause the roller to move away from the furnace body. Since the sliding wheel seat can move relative to the base, when the roller is affected by the action force, the action force will be transmitted to the sliding wheel seat, causing the sliding wheel seat to move away from the furnace body and remain in the moved position under the action of the elastic locking mechanism. This allows the roller and the furnace body to have a local gap, which can help maintenance personnel quickly determine whether the ash tray has a lateral inclination, without the need for complex detection to quickly find problems and avoid affecting production efficiency.

[0010] The elastic locking mechanism can be a combination of a bolt, a nut and a spring. The first connecting arm and the second connecting arm are both provided with through holes. The bolt passes through the spring, then passes through the through holes of the first connecting arm and the second connecting arm, and is locked by the nut. The spring abuts against the first connecting arm or the second connecting arm. During installation, the roller abuts against the furnace body, the bolt and the nut are tightened and adjusted, so that the first connecting arm and the second connecting arm can rotate relative to each other, and the included angle between the second connecting arm and the first connecting arm can remain horizontal after rotation, without being loose. The spring can prevent the sliding wheel seat from re-contacting the furnace body due to its own gravity after moving away from the furnace body. The relative rotation of the first connecting arm and the second connecting arm also facilitates installation and debugging.

[0011] As an extension of the above scheme, the roller is a rubber material member. Since the furnace body is a steel water jacket, if a metal or other hard roller is used, it is easy to cause damage to the furnace body. The rubber roller can ensure smooth rotation of the roller around the outer wall of the furnace body, and will not cause damage to the furnace body.

[0012] As an extension of the above scheme, the first connecting arm is connected with a first rotating disc, the second connecting arm is connected with a second rotating disc, the first rotating disc and the second rotating disc are provided with a center hole, and the first rotating disc, the second rotating disc and the elastic locking mechanism are coaxially connected to make the first rotating disc and the second rotating disc tightly fixed. The first rotating disc and the second rotating disc are tightly fixed, which can increase the contact area of the connecting area of the first connecting arm and the second connecting arm. Under the action of the elastic locking mechanism, the friction between the first connecting arm and the second connecting arm can be increased, so as to avoid the second connecting arm from descending under the action of the sliding wheel seat during operation, thereby ensuring that the second connecting arm will not droop again after rotating when the ash tray tilts, and ensuring the stable operation of the first detection device.

[0013] As an extension of the above scheme, one end surface of the first rotating disc and the second rotating disc in contact is provided with a groove, one end surface of the second rotating disc in contact with the first rotating disc is provided with a protruding tooth, and the protruding tooth is matched with the groove. By matching the protruding tooth with the groove, the friction between the first connecting arm and the second connecting arm can be further increased, so as to avoid the second connecting arm from drooping again.

[0014] It should be noted that the furnace body is generally a steel water jacket, and the ash tray is also very heavy. Once the ash tray tilts, the force driving the roller away from the furnace body will be much greater than the locking force of the elastic locking mechanism, so as to drive the second connecting arm to rotate around the first connecting arm. The locking force of the elastic locking mechanism is greater than the downward force on the side of the second connecting arm connected to the sliding wheel seat, so as to prevent the second connecting arm from rotating again.

[0015] As an extension of the above scheme, the first detection device further comprises a shell, the shell is provided with a first opening, the first opening is arranged on the side wall of the shell, the sliding wheel seat passes through the first opening, and the shell is connected with the base. By adding the shell to the first detection device, the elastic locking mechanism can not directly contact the external space, and the service life of the elastic locking mechanism can be prolonged. The first opening can ensure that the roller can pass through the shell and abut against the furnace body.

[0016] As an extension of the above scheme, the shell is further provided with a second opening, the second opening is arranged on the top of the shell, the top of the shell is provided with a sliding groove, the sliding groove is connected with a display panel, the display panel covers the second opening, the display panel is connected with a connecting rod, and the connecting rod is connected with the sliding wheel seat.

[0017] The position relationship between the roller and the furnace body can be further enlarged by opening a second opening at the top of the shell and slidingly connecting a display plate at the second opening, so that the display plate is connected with the first support, and the detection personnel can more quickly and intuitively determine whether the ash tray and the furnace body exist the side inclination.

[0018] Specifically, when installing, the roller abuts against the furnace body, the elastic locking mechanism is locked, the shell is placed on the base cover, the display plate provided with a connecting rod is placed in the sliding groove, the connecting rod passes through the second opening and is connected with the first support, and the display plate is marked to record the original position information. When the side inclination exists, the sliding wheel seat is displaced, the display plate is displaced by the connecting rod, and the mark on the display plate changes from the original position. This setting is more intuitive than observing whether a gap exists between the roller and the furnace body.

[0019] Since the side inclination between the ash tray and the furnace body may not be large, the gap between the roller and the furnace body is not necessarily obvious. However, by setting the display plate, the problem between the roller and the furnace body can be enlarged. If the side inclination does not exist, the mark on the display plate should be consistent with the original position. If the side inclination exists, the mark on the display plate deviates from the original position.

[0020] As an extension of the above scheme, the sliding groove is arranged on the outer wall at the top of the shell. In this way, the shell is convenient to process, and the display plate is convenient to install.

[0021] As an extension of the above scheme, the shell is connected with a connecting column, and the base is provided with a connecting hole matched with the connecting column. By arranging the connecting column on the shell and arranging the connecting hole on the base, the shell and the base are convenient to install, disassemble and produce.

[0022] As an extension of the above scheme, the shell is provided with a level. The level can also be used to determine whether the side inclination exists between the ash tray and the furnace body. On the other hand, when the side inclination exists between the ash tray and the furnace body, it can be determined whether the side inclination exists in the ash tray or the furnace body. When the position information of the level does not change, and the side inclination indeed exists between the ash tray and the furnace body, it can be preliminarily determined that the furnace body may have a settlement problem.

[0037] Reference Figures 1 to 8 , the following will be described in the description of the utility model a cross partition wall type rotating bed gasification furnace is raised several embodiments.

[0038] As Figures 1 to 8 shown, in some embodiments, a cross partition wall type rotating bed gasification furnace, including furnace body 100, ash tray 200, dry distillation section 300, set in the bottom of the furnace body 100 tower type furnace grate 400, the furnace body 100 top connection dry distillation section 300, the furnace body 100 bottom part is located in the ash tray 200 and the ash tray 200 rotates around the furnace body 100, the ash tray 200 is connected with the tower type furnace grate 400, the furnace body 100 includes first water jacket 101, second water jacket 102, the second water jacket 102 is arranged above the first water jacket 101, the second water jacket 102 is connected with the first water jacket 101, the second water jacket 102 is connected with the dry distillation section 300, two fire observation openings 500 are symmetrically arranged on the second water jacket 102, the fire observation opening 500 includes first fire hole 501 and second fire hole 502, the first fire hole 501 is arranged at the top of the second water jacket 102 and extends to the inside of the second water jacket 102, the second fire hole 502 is arranged on the side wall of the upper part of the second water jacket 102, the axis of the first fire hole 501 points to the side wall of the tower type furnace grate 400, and the axis of the second fire hole 502 points to the top of the tower type furnace grate 400.

[0039] By setting the second water jacket 102 in combination with the first water jacket 101 into the furnace body 100, the furnace body 100 can be divided into two components for production and reassembly. When producing the furnace body 100, the furnace body 100 does not need to be integrally formed, which can reduce the processing size of the furnace body 100 and reduce the production difficulty. Secondly, due to the different temperatures in different regions inside the furnace body 100, the pressures of the water vapor inside the water jackets in different regions are different, and the pressure inside the water jacket in the high-temperature region is greater. Therefore, the water jacket in the high-temperature region needs stronger pressure-bearing capacity. When the same steel material is used to make the furnace body, the water jacket in the high-temperature region must be thicker. By setting the furnace body 100 to be in combination of the first water jacket 101 and the second water jacket 102, water jackets of different thicknesses can be produced for different temperatures in different regions inside the furnace body 100. It is not necessary to use the same thickness of steel material to make the water jacket that constitutes the furnace body, which is beneficial to save cost and reduce resource consumption. Of course, it is also possible to use steel materials with the same pressure-bearing capacity to produce the furnace body, which can still reduce the difficulty of production and processing, although it cannot save resources. In addition, by setting the first fire detection hole 501 on the top of the second water jacket 102 and the second fire detection hole 502 on the upper side wall of the second water jacket 102, it is more convenient to observe the combustion of coal particles inside the furnace body 100. When using a fire probe, the combustion of coal particles at the top and bottom of the tower furnace grate 400 can be detected at the same time. Among them, since the cross partition wall type rotating bed gasifier has four feeding cavities, the two fire observation holes 500 are symmetrically arranged relative to the axis of the furnace body. During the rotation of the tower furnace grate 400, the combustion of coal particles falling into the feeding cavities can be detected with fewer times, which can save manpower and reduce the probability of gas seal failure.

[0040] In some embodiments, the upper surface of the ash tray 200 is provided with a first detection device 600 for detecting whether there is a side tilt between the ash tray 200 and the furnace body 100.

[0041] The first detection device 600 includes a base 601, a first support 602, and a sliding wheel seat 603. One end of the first support 602 is connected to the base 601, and the other end of the first support 602 is connected to the sliding wheel seat 603. The sliding wheel seat 603 can move relative to the base 601 and maintain the posture after moving. The base 601 is connected to the top of the ash tray 200. The sliding wheel seat 603 is provided with a roller 604 made of rubber. The roller 604 abuts against the furnace body 100.

[0042] The sliding wheel seat 603 comprises an upper seat 6031 and a lower seat 6032, and a stopper 6033 is arranged between the upper seat 6031 and the lower seat 6032. The upper seat 6031 and the lower seat 6032 are provided with shaft holes 6034 in the vertical direction. The roller 604 is connected with the sliding wheel seat 603 through a shaft pin 6035 which is coaxial with the shaft hole 6034. The sliding wheel seat 603 is provided with a first mounting portion 6036 connected with the first support 602 at the end.

[0043] The sliding wheel seat 603 can move relative to the base 601 in a translational or rotational manner. When the translational manner is selected, the base 601 is provided with a first sliding groove 6011. The first support 602 comprises a first connecting arm 6021 and a second connecting arm 6022. The first support 602 is connected with a first sliding block 6012 below. The first support 602 is in sliding connection with the base 601, and the first sliding block 6012 and the first sliding groove 6011 have sufficient damping. The other end of the first support 602 is connected with the first mounting portion 6036.

[0044] In the initial installation state, the roller 604 rotatable on the sliding wheel seat 603 is adjusted to abut against the furnace body 100. When the ash tray 200 rotates around the furnace body 100, the roller 604 follows. When the ash tray 200 and the furnace body 100 are inclined due to various reasons, the rotation track of the ash tray 200 changes, so that the roller 604 is closer to the furnace body 100 in a local area during the following process. As a result, the roller 604 and the furnace body 100 have an acting force which promotes the roller 604 to move away from the furnace body 100. Since the sliding wheel seat 603 can move relative to the base 601, when the roller 604 is affected by the acting force, the acting force is transmitted to the sliding wheel seat 603, so that the sliding wheel seat 603 moves away from the furnace body 100. The first support 602 can keep the relative position of the sliding wheel seat 603 after displacement. In this way, a local gap is generated between the roller 604 and the furnace body 100, which can help the maintenance personnel to quickly determine whether the ash tray 200 and the furnace body 100 are inclined. The problem can be found in time without complex detection.

[0045] In some embodiments, the sliding wheel seat 603 is moved relative to the base 601 in a rotating manner. The first support 602 comprises a first connecting arm 6021 and a second connecting arm 6022, both of which are provided with through holes. An elastic locking mechanism 605 passes through the through holes to fix the first connecting arm 6021 and the second connecting arm 6022, and enables the second connecting arm 6022 to rotate relative to the first connecting arm 6021. The first connecting arm 6021 is connected to the base 601, and the second connecting arm 6022 is connected to the sliding wheel seat 603.

[0046] Specifically, the elastic locking mechanism 605 can be a combination of a bolt, a nut and a spring. The bolt passes through the spring and then passes through the through holes in the first connecting arm 6021 and the second connecting arm 6022, connecting the first connecting arm 6021 and the second connecting arm 6022 and fixing them by the nut. The spring abuts against the first connecting arm 6021 or the second connecting arm 6022.

[0047] During installation, the roller 604 abuts against the furnace body 100, the bolt and the nut are tightened and adjusted, the locking force is adjusted, the first connecting arm 6021 and the second connecting arm 6022 can rotate relative to each other, and the included angle between the second connecting arm 6022 and the first connecting arm 6021 can be kept at the angle after rotation, so that the second connecting arm 6022 does not sag. The spring can prevent the sliding wheel seat 603 from contacting the furnace body 100 again due to its own gravity after moving away from the furnace body 100. The relative rotation of the first connecting arm 6021 and the second connecting arm 6022 also facilitates installation and adjustment.

[0048] Further, the first connecting arm 6021 is connected with a first rotating disc 6023, the second connecting arm 6022 is connected with a second rotating disc 6024, the first rotating disc 6023 and the second rotating disc 6024 are both provided with a center hole 6025, the first rotating disc 6023, the second rotating disc 6024 and the elastic locking mechanism 605 pass through the center hole 6025 to connect and keep close the first connecting arm 6021 and the second connecting arm 6022. By connecting the first connecting arm 6021 and the second connecting arm 6022 through the rotating disc, the contact area between the first connecting arm 6021 and the second connecting arm 6022 can be increased, the friction between the first connecting arm 6021 and the second connecting arm 6022 can be increased under the action of the elastic locking mechanism, and the second connecting arm 6022 is prevented from descending under the gravity of the sliding wheel seat 603 in the running process, so as to ensure that the second connecting arm 6022 does not droop again after rotating when the ash tray 200 and the furnace body exist lateral inclination, and the stable operation of the first detection device 600 is ensured.

[0049] Further, one side of the first rotating disc 6023 and the second rotating disc 6024 in contact is provided with a groove 6026, one side of the second rotating disc 6024 in contact with the first rotating disc 6023 is provided with a convex tooth 6027, and the convex tooth 6027 is matched with the groove 6026. By matching the convex tooth 6027 with the groove 6026, the friction between the first connecting arm 6021 and the second connecting arm 6022 can be further increased, and the second connecting arm 6022 can be better prevented from drooping again.

[0050] It should be noted that the furnace body 100 is generally a steel water jacket, and the ash tray 200 is also very heavy. Once the ash tray 200 and the furnace body 100 exist lateral inclination, the driving force of the roller 604 away from the furnace body 100 will be much greater than the locking force of the elastic locking mechanism 605, so as to drive the second connecting arm 6022 to rotate around the first connecting arm 6021, and the locking force of the elastic locking mechanism 605 is greater than the downward force on the side of the second connecting arm 6022 connected with the sliding wheel seat 603, so that the second connecting arm 6022 cannot rotate again.

[0051] In some embodiments, the first detection device 600 further comprises a housing 606, at least one connecting column 6066 is connected to the inner wall of the housing 606, the connecting column 6066 protrudes from the bottom of the housing 606, a first opening 6061 is arranged on the housing 606, the first opening 6061 is arranged on the side wall of the housing 606, the sliding wheel seat 603 passes through the first opening 6061, at least one connecting hole 6067 is arranged on the base 601, and the connecting column 6066 is connected with the connecting hole 6067 so that the housing 606 is connected with the base 601. By adding the housing 606 to the first detection device 600, the elastic locking mechanism 605 cannot directly contact the external space, and the service life of the elastic locking mechanism 605 can be prolonged, and the first opening 6061 can ensure that the roller 604 can pass through the housing 606 and abut against the furnace body 100.

[0052] A second opening 6062 is further arranged on the housing 606, the second opening 6062 is arranged on the top of the housing 606, a sliding groove 6063 is arranged on the outer wall of the top of the housing 606, a display plate 6064 is connected to the sliding groove 6063, the display plate 6064 covers the second opening 6062, a connecting rod 6065 is connected to the display plate 6064, and the connecting rod 6065 is connected with the sliding wheel seat 603. The second opening 6062 is rectangular, two parallel edges of the second opening 6062 are perpendicular to the radial direction of the furnace body 100, and the sliding groove 6063 is arranged on the two sides of the two parallel edges, so that the display plate 6064 is allowed to move in a direction perpendicular to the radial direction of the furnace body 100.

[0053] By arranging the second opening 6062 on the top of the housing 606 and slidingly connecting the display plate 6064 at the second opening 6062, the display plate 6064 is connected with the first support 602, and the positional relationship between the roller 604 and the furnace body can be further enlarged, so that the detection personnel can more quickly and intuitively determine whether the ash tray 200 and the furnace body 100 exist in a side inclination condition.

[0054] Specifically, when installing, the roller 604 is abutted against the furnace body 100, and the elastic locking mechanism 605 is locked, then the shell 606 is covered on the base 601, the display plate 6064 provided with the connecting rod 6065 is put into the sliding groove 6063, the connecting rod 6065 is connected with the first mounting portion 6036 through the second opening 6062, and the display plate 6064 is marked to record the original position information, when there is a side inclination, the sliding wheel base 603 is displaced, then the display plate 6064 is displaced by the connecting rod 6065, and the mark on the display plate 6064 is changed, which is more intuitive than observing whether there is a gap between the roller 604 and the furnace body 100. The mark can be a scale, a marking line, paint spraying or the like on the display plate 6064 or the sliding groove 6063.

[0055] Since the range of the side inclination between the ash tray 200 and the furnace body 100 can be small, the gap between the roller 604 and the furnace body 100 can not be obvious, but the display plate 6064 can be arranged to magnify the problem between the roller 604 and the furnace body 100, if there is no side inclination, the mark on the display plate 6064 should be consistent with the original position, and if there is a side inclination, the mark on the display plate 6064 is deviated from the original position.

[0056] In some embodiments, the shell 606 is provided with a level 607, the level 607 can also be arranged to facilitate observing whether there is a side inclination between the ash tray 200 and the furnace body 100. On the other hand, when there is a side inclination between the ash tray 200 and the furnace body 100, the level 607 can assist in judging whether the ash tray 200 or the furnace body 100 is inclined. When the position information of the level 607 does not change, and there is indeed a side inclination between the ash tray 200 and the furnace body 100, it can be preliminarily judged that the furnace body 100 can have a settlement problem, and the furnace body 100 is inclined.

[0057] The preferred embodiments of the utility model are described in detail above, but the utility model creation is not limited to the embodiments, and those skilled in the art can make various equivalent modifications or replacements without departing from the spirit of the utility model, and these equivalent modifications or replacements are all included in the range defined by the claims of the present application.
