As shown in fig. 1, an embodiment of the present utility model provides a tube type heat exchanger with a cleaning device, which is provided with a tube side 1 and a shell side 2, wherein the tube side 1 is provided with a tube side inlet 3 and a tube side outlet 4, the shell side 2 is provided with a shell side inlet 5 and a shell side outlet 6, and high-temperature or low-temperature fluid passes through the shell side 2 and low-temperature or high-temperature fluid passes through the tube side 1, so as to exchange heat in the heat exchanger, thereby achieving the purpose of cooling high-temperature fluid. For example, when the low-temperature fluid is cooling water and the cooling water passes through the tube pass 1 for a long time, microorganisms or dirt are deposited on the inner wall of the tube pass 1 to form a layer of heat insulation material, so that the heat transfer coefficient of the heat exchanger is reduced, and the heat exchange effect is seriously reduced.
Based on this, the tube array heat exchanger of the present utility model further comprises a handle 7, a first stopper 8, a pull rod 9, a second stopper 10 and a brush 11.
The handle 7 and the first limiting block 8 are arranged at the first end of the pull rod 9, the brush 11 and the second limiting block 10 are arranged at the second end of the pull rod 9, and the second end of the pull rod 9 can enter the tube side 1 and also can penetrate out of the second end of the tube side 1. The first limiting block 8 is used for limiting and preventing the whole first end of the pull rod 9 from entering the tube side 1, and the second limiting block 10 is used for limiting and preventing the whole second end of the pull rod 9 from moving out of the first end of the tube side 1.
In this embodiment, the cover 12 and the mechanical seal 13 are further provided, where the cover 12 is detachably connected to the shell side 2 through a bolt, and is used as a part of the tube side 1, and the cover 12 is provided with a plurality of perforations for the pull rod 9 to enter, and the perforations are sealed by the mechanical seal 13, so that the inside of the tube side 1 maintains the liquid tightness.
Also as shown in fig. 2, in the present embodiment, the brush 11 includes a brush body 14 and bristles 15 formed on the brush body 14 to be densely distributed. The brush body 14 has a circular head, and the outer diameter of the brush body 14 is smaller than the inner diameter of the tube side 1, so that the brush body can smoothly enter the tube side 1, and the outer diameter of the cylindrical surface formed by the bristles 15 is larger than the inner diameter of the tube side 1, so that the interior of the tube side 1 can be effectively brushed.
As a further improvement, in this embodiment, the brush body 14 is further provided with a hole 16 for allowing the cooling water to flow therethrough, so as to ensure that the brush 11 is not affected by the water pressure during movement.
When the microorganism or dirt on the inner wall of the tube side 1 needs to be cleaned, the handle 7 is pulled to enable the pull rod 9 and the brush 11 to enter the tube side 1 to the right side in the drawing, and the head of the brush body 14 is circular and the outer diameter of the brush body is smaller than the inner diameter of the tube side 1, so that the brush body can be ensured to smoothly enter the tube side 1. After entering the tube side 1, the outer diameter of the brush hair 15 is larger than the inner diameter of the tube side 1, so that microorganisms or dirt in the tube side 1 can be effectively rubbed, and the microorganisms or dirt are released and washed away by cooling water flow; and the brush body 14 is provided with the holes 16, so that cooling water can flow through the holes, and the brush 11 is ensured not to be influenced by water pressure during movement. The pull rod 9 is pulled to the right until the second limiting block 10 touches the sealing cover 12, and the pulling is stopped, so that the brush 11 is prevented from falling out of the tube side 1 as a whole. And then the pull rod 9 is pushed to the left until the first limiting block 8 touches the mechanical sealing piece 13, so that the cleaning of the tube side 1 can be completed once.
In a word, the scheme that this embodiment provided is adopted, can control handle 7 in the heat exchanger use, through pull rod 9 with brush 11 at the inside reciprocating motion of tube side, when inside through tube side 1, the brush hair 15 on the brush 11 will clear up microorganism or dirt on the tube side 1, can reach like this and clean tube side 1 inside under the circumstances that does not dismantle the end cover and does not shut down, guarantees the heat transfer effect of heat exchanger.
While the foregoing is directed to the preferred embodiments of the present utility model, it will be appreciated by those skilled in the art that various modifications and adaptations can be made without departing from the principles of the present utility model, and such modifications and adaptations are intended to be comprehended within the scope of the present utility model.
