Description

Technical Field

[0001] The present invention relates to the technical field of shell and tube heat exchangers, in particular to a shell and tube heat exchanger with a self-cleaning structure. Background Art

[0002] A shell and tube heat exchanger is a type of heat exchange equipment that achieves heat exchange between different media through the wall of a tube bundle enclosed in a shell. Due to its advantages such as high heat transfer efficiency, solid structure, strong adaptability, easy maintenance and low cost, shell and tube heat exchangers are widely used in the chemical industry, petroleum industry, food industry, new energy and environmental protection fields. When a shell and tube heat exchanger is in use, deposition, scaling or corrosive impurities are prone to occur on the inner wall of the shell and the outer surface of the tube bundle. Therefore, the shell and tube heat exchanger needs to be cleaned frequently to ensure heat exchange efficiency and effect.

[0003] In the prior art, when cleaning a shell and tube heat exchanger, most of the methods are to place a cleaning device inside the shell for cleaning or to disassemble the shell and tube heat exchanger for cleaning. When the cleaning device is placed inside the shell for cleaning, due to the internal space limitation of the shell and tube heat exchanger and the inability of the staff to see the internal structure of the shell and tube heat exchanger clearly, it is not only difficult to clean the cleaning device, but also easy to damage the internal parts of the shell and tube heat exchanger. When the shell and tube heat exchanger is disassembled for cleaning, the shell and tube heat exchanger needs to be disassembled first, and then installed after cleaning. Since the disassembly and installation of the shell and tube heat exchanger are relatively time-consuming, this cleaning method is not only inefficient but also too time-consuming, thereby affecting the working efficiency of the shell and tube heat exchanger.

When the pair of cleaning plates 7 rotates with the rotation of the rotating shaft 4, thereby cleaning the inner wall of the shell 201, the rotation of the pair of cleaning plates 7 drives the annular rack 12 rotates, and since the annular rack 12 and the pair of gears 11 are meshed with each other, the annular rack 12 drives the pair of gears 11 to rotate, and the pair of gears 11 drives the pair of reciprocating rods 9 to rotate, and the rotation of the pair of reciprocating rods 9 drives the pair of reciprocating plates 10 to reciprocate, and the outer side walls of the horizontal and vertical parts of a group of tube bundles of the tube body 202 are cleaned.

Because a pair of gears 27 are meshed with the annular rack 25, and the annular rack 25 is fixed to one side of the outer wall of the tube body 202, it is in a fixed state. , when a pair of gears three 27 rotates, the annular rack three 25 rotates, so that the rotating gear three 27 drives the pair of reciprocating rods three 26 to rotate, and the rotation of the pair of reciprocating rods three 26 drives the adjusting block 28 to reciprocate, so that the adjusting block 28 drives the square plate 702 to reciprocate, thereby driving the bristles 1 on the square plate 702 and the cleaning nozzle 23 to reciprocate, so that the bristles 1 clean and wipe the inner side wall of the shell 201 back and forth, while the cleaning nozzle 23 increases the water spraying range through the reciprocating motion, so that the bristles 1 wipe the place where the cleaning nozzle 23 sprays water. , thereby not only improving the cleaning effect of the bristle pair on the shell 201, but also improving the coordination effect of the bristle one and the cleaning nozzle 23, so that the cleaning effect of the bristle one and the cleaning nozzle 23 is further improved, thereby further improving the cleaning efficiency of the bristle one and the cleaning nozzle 23 on the inner wall of the shell 201, reducing the time required for cleaning the shell 201, thereby not only improving the working efficiency of the shell and tube heat exchanger body 2, but also because the cleaning time is reduced, the energy consumption is further reduced, thereby further improving the energy saving and consumption reduction effect of the device.

[0035] The cleaning member includes a slide rod 13; one end of the outer wall of the slide rod 13 is slidably connected to one side of the outer wall of the tube body 202; a fixed plate 14 is fixedly connected to one side of the outer wall of the slide rod 13; a pair of curved plates 15 are fixedly connected to one side of the outer wall of the fixed plate 14; an intermediate plate 16 is fixedly connected to one side of the outer wall of the fixed plate 14, and the intermediate plate 16 is located between the pair of curved plates 15; a brush 17 is fixedly connected to the outer surface of the opposite side of the outer wall of the pair of curved plates 15 and the outer surface of the intermediate plate 16, and the brush 17 is fixedly connected to the tube The bending part of a group of tube bundles of the body 202 matches; one side of the outer wall of the tube body 202 is rotatably connected to a reciprocating rod 2 18 through a square plate 1; one end of the outer wall of the reciprocating rod 2 18 passes through the fixed plate 14, and the reciprocating rod 2 18 matches the fixed plate 14; one end of the outer wall of the reciprocating rod 2 18 is fixedly connected to a gear 2 19; one side of the outer wall of the connecting plate 6 is fixedly connected to an annular rack 20, and the annular rack 20 and the gear 2 19 are meshed with each other. When the connecting plate 6 rotates, the rotation of the connecting plate 6 is brought The movable annular rack 20 rotates.

The rotation of the reciprocating rod 2 18 drives the fixed plate 14 to reciprocate, and the fixed plate 14 drives the pair of arc plates 15, the middle plate 16 and the multiple sets of brushes 2 17 to reciprocate, so that the multiple sets of brushes 2 17 clean the outer surface of the curved part of a group of tube bundles of the tube body 202. In combination with the cleaning of the reciprocating plate 10, the entire outer surface of the group of tube bundles of the tube body 202 is cleaned, thereby improving the cleaning effect of the device on the group of tube bundles of the tube body 202. Moreover, since the curved part of the group of tube bundles of the tube body 202, the horizontal and vertical parts of the group of tube bundles of the tube body 202 and the inner side wall of the shell 201 are cleaned at the same time, the time required for cleaning is reduced, and the cleaning efficiency is improved.

When the reciprocating plate 10 reciprocates, the reciprocating motion of the reciprocating plate 10 drives the multiple groups of rotating rods 31 and the water wheel blades 32 to rotate. When the water wheel blades 32 move with the reciprocating plate 10 in the water, the water wheel blades 32 are moved by the water flow to the water wheel blades The impact force of the plate 32 and the torque generated thereby drive the rotating rod 31 to rotate, so that the rotating rod 31 drives the multiple sets of gears 5 33 to rotate. Since the multiple sets of gears 5 33 and the multiple sets of gears 4 30 are meshed with each other, the gear 5 33 drives the auxiliary shell 29 to rotate through the gear 4 30, so that the auxiliary shell 29 assists the reciprocating plate 10 to clean the horizontal and vertical parts of a group of tube bundles of the tube body 202.

When water or other liquid is introduced into the water inlet pipe 22 of the shell 201 for heat exchange, the water and liquid will contact a part of the energy-saving plate 37 when entering the water inlet pipe 22 of the shell 201. Under the impact of the water or liquid, the energy-saving plate 37 rotates, and the energy-saving plate 37 drives the rotating rod 1 36 to rotate, and the rotating rod 1 36 drives the bevel gear 7 40 to rotate through the bevel gear 6 38, and the bevel gear 7 40 drives the rotating rod 2 39 to rotate, and then drives the rotating shaft 4 to rotate through the sprocket 1 41 and the chain 1 42, so that the rotating shaft 4 drives the connecting pipe 5, the connecting plate 6 and the cleaning plate 7 and other cleaning mechanisms to rotate, which can effectively reduce the consumption of traditional energy, thereby reducing energy consumption costs while meeting the requirements of energy saving and consumption reduction.

[0040] The outer wall of the housing 201 is rotatably connected to a rotating rod 3 43 through a pair of blocks 2; one end of the outer wall of the rotating rod 3 43 and the outer wall of the rotating rod 2 39 are fixedly connected to a sprocket 2 44, and the pair of sprockets 2 44 are connected by a chain 2 45; a group of soft rods 46 are fixedly connected to the outer walls of the rotating rod 3 43 and the rotating rod 2 39; one end of the outer wall of the two groups of soft rods 46 are fixedly connected to a vibration ball 47, and the two groups of vibration balls 47 are matched with the outer wall of the housing 201. When the rotating rod 2 39 rotates, the rotating rod 2 39 drives the rotating rod 3 43 to rotate through the sprocket 2 44 and the chain 2 45, so that the rotating rod 3 Rod 2 39 and rotating rod 3 43 simultaneously drive the soft rod 46 and the vibration ball 47 to rotate, so that the vibration ball 47 knocks on the shell 201 to generate vibration. The vibration force can shake off or disperse impurities adhering to the inner wall of the shell 201, so that the vibration force assists the cleaning plate 7 and the brush 1 8 to clean the inner wall of the shell 201. The brush 1 8 and the cleaning nozzle 23 are more convenient to clean the inner wall of the shell 201, and some impurities that are difficult to clean are also easier to be cleaned with the assistance of the vibration force, so that the cleaning effect of the inner wall of the shell 201 is further improved.

[0041] When the present invention is in use, the motor 3 drives the rotating shaft 4 to rotate, so that the rotating shaft 4 drives the connecting pipe 5, the connecting plate 6 and a pair of cleaning plates 7 to rotate, so that the brush 8 on the cleaning plate 7 cleans the inner wall of the shell 201.

[0042] When a pair of cleaning plates 7 drives the brush 8 to clean the inner wall of the shell 201, by connecting the external water source to the water pipe 22, the water source is sprayed through the water pipe 22, the annular shell 21, the connecting pipe 5, the connecting plate 6, the pair of cleaning plates 7 and the two groups of cleaning nozzles 23, so that the sprayed water cooperates with the brush 8 to clean, so that the cleaning effect of the brush 8 is better.

[0043] The cleaning plate 7 includes a cleaning shell 701 and a square plate 702. When the cleaning shell 701 rotates, the reciprocating rod 3 26 is driven to rotate. Since a pair of gears 3 27 are engaged with the annular rack 3 25, and the annular rack 3 25 is fixed to one side of the outer wall of the tube body 202 and is in a fixed state, when the pair of gears 3 27 rotates, the annular rack 3 25 rotates, so that the rotating gear 3 27 drives the pair of reciprocating rods 3 26 to rotate, and the rotation of the pair of reciprocating rods 3 26 drives the adjusting block 28 to reciprocate, so that the adjusting block 28 drives the square plate 702 to reciprocate, thereby driving the bristles 1 on the square plate 702 and the cleaning nozzle 23 to reciprocate, so that the bristles 1 move back and forth against the shell While cleaning and wiping the inner wall of 201, the cleaning nozzle 23 also increases the water spraying range through reciprocating motion, so that the bristles one wipe the places where the cleaning nozzle 23 sprays water, thereby not only improving the cleaning effect of the bristles one on the shell 201, but also improving the coordination effect of the bristles one and the cleaning nozzle 23, so that the cleaning effect of the bristles one and the cleaning nozzle 23 is further improved, thereby further improving the cleaning efficiency of the bristles one and the cleaning nozzle 23 on the inner wall of the shell 201, reducing the time required for cleaning the shell 201, and because the cleaning time is reduced, the energy consumption is further reduced, so that the energy saving and consumption reduction effect of the device is further improved.

[0044] When the pair of cleaning plates 7 rotates along with the rotation of the rotating shaft 4, the rotation of the pair of cleaning plates 7 drives the annular rack 12 to rotate. Since the annular rack 12 and the pair of gears 11 are meshed with each other, the annular rack 12 drives the pair of gears 11 to rotate, and the pair of gears 11 drives the pair of reciprocating rods 9 to rotate. The rotation of the pair of reciprocating rods 9 drives the pair of reciprocating plates 10 to reciprocate, thereby cleaning the outer side walls of the horizontal and vertical parts of a group of tube bundles of the tube body 202. Since the reciprocating plates 10 and the cleaning plates 7 are cleaned at the same time, the time required for cleaning the entire shell and tube heat exchanger body 2 is reduced, the cleaning efficiency is improved, and the energy consumption is reduced, so that the device achieves the effect of energy saving and consumption reduction.

[0045] When the reciprocating plate 10 reciprocates, the reciprocating motion of the reciprocating plate 10 drives the multiple sets of rotating rods 31 and the water wheel blades 32 to rotate. When the water wheel blades 32 move with the reciprocating plate 10 in the water, the impact force of the water flow on the water wheel blades 32 and the torque generated thereby drive the rotating rods 31 to rotate, so that the rotating rods 31 drive the multiple sets of gears 5 33 to rotate. Because the multiple sets of gears 5 33 and the multiple sets of gears 4 30 are meshed with each other, the gears 5 33 drive the auxiliary shell 29 to rotate through the gears 4 30, so that the auxiliary shell 29 assists The reciprocating plate 10 cleans the transverse and vertical parts of a group of tube bundles of the tube body 202. Since the auxiliary shell 29 moves and rotates at the same time, the cleaning effect of the auxiliary shell 29 is better. Therefore, when the reciprocating plate 10 is used for cleaning, the cleaning efficiency and cleaning effect are better. In combination with the brush 1 8, the cleaning nozzle 23 and the brush 2 17, the overall cleaning efficiency of the shell and tube heat exchanger body 2 is higher and the effect is better, which can further reduce the number of cleaning times and cleaning time of the shell and tube heat exchanger body 2, effectively reduce energy consumption, and thus effectively achieve energy saving and consumption reduction effects.

[0046] When the connecting plate 6 rotates, the rotation of the connecting plate 6 drives the annular rack 20 to rotate. Since the annular rack 20 and the gear 2 19 are meshed with each other, the annular rack 20 drives the gear 2 19 to rotate, and the gear 2 19 drives the reciprocating rod 2 18 to rotate. The rotation of the reciprocating rod 2 18 drives the fixed plate 14 to reciprocate, and the fixed plate 14 drives a pair of arc plates 15, the middle plate 16 and the multiple sets of brushes 2 17 to reciprocate, so that the multiple sets of brushes 2 17 are on the outer side of the bend of a group of tube bundles of the tube body 202. The surface is cleaned, thereby cooperating with the cleaning of the reciprocating plate 10, so that the entire outer surface of a group of tube bundles of the tube body 202 is cleaned, thereby improving the cleaning effect of the device on a group of tube bundles of the tube body 202, and because the bending parts of a group of tube bundles of the tube body 202, the horizontal and vertical parts of a group of tube bundles of the tube body 202 and the inner side wall of the shell 201 are cleaned at the same time, the time required for cleaning is reduced, the cleaning efficiency is improved, and the energy consumption is reduced due to the reduction in cleaning time, thereby achieving energy-saving effects.

[0047] When water or other liquids enter the water inlet pipe 22 of the shell 201 for heat exchange, the water and liquid will contact a part of the energy-saving plate 37 when entering the water inlet pipe 22 of the shell 201. Under the impact force of the water or liquid, the energy-saving plate 37 will rotate, and the energy-saving plate 37 will drive the rotating rod 1 36 to rotate, so that the rotating rod 1 36 drives the bevel gear 7 40 to rotate through the bevel gear 6 38, and the bevel gear 7 40 drives the rotating rod 2 39 to rotate, and then drives the rotating shaft 4 to rotate through the sprocket 1 41 and the chain 1 42, so that the rotating shaft 4 drives the connecting pipe 5, the connecting plate 6 and the cleaning plate 7 and other cleaning mechanisms to rotate, which can effectively reduce the consumption of traditional energy, thereby reducing energy consumption costs while achieving the requirements of energy saving and consumption reduction.

[0048] When the rotating rod 2 39 rotates, the rotating rod 2 39 drives the rotating rod 3 43 to rotate through the sprocket 2 44 and the chain 2 45, so that the rotating rod 2 39 and the rotating rod 3 43 simultaneously drive the soft rod 46 and the vibration ball 47 to rotate, so that the vibration ball 47 knocks on the shell 201 to generate vibration. The vibration force can shake off or disperse impurities adhering to the inner wall of the shell 201, so that the vibration force assists the cleaning plate 7 and the brush 1 8 to clean the inner wall of the shell 201. The brush 1 8 and the cleaning nozzle 23 are more convenient to clean the inner wall of the shell 201, and some impurities that are difficult to clean are also easier to be cleaned with the assistance of the vibration force, so that the cleaning effect of the inner wall of the shell 201 is further improved.

[0049] A protective shell 34 is fixedly connected to opposite sides of the outer wall of a pair of reciprocating plates 10, so that the gear 4 30 and the gear 5 33 are protected by the protective shell 34, making the gear 4 30 and the gear 5 33 not easily damaged.

[0050] When the device cleans the shell and tube heat exchanger body 2 as a whole, the cleaning range and cleaning strength of the cleaning mechanism in the device are pre-set, so it is not easy to cause damage to the shell and tube heat exchanger body 2, and no manual cleaning is required, thereby reducing the cleaning difficulty and labor costs, thereby improving the working efficiency of the shell and tube heat exchanger body 2.
