The shell and tube heat exchanger is the most widely used heat exchanger in chemical industry and alcohol production. It is mainly composed of a shell, a tube plate, a heat exchange tube, a seal head, a baffle plate and the like. The required material can be respectively made of common carbon steel, red copper or stainless steel. When heat exchange is carried out, a fluid enters from the connecting pipe of the end socket, flows in the pipe and flows out from the outlet pipe at the other end of the end socket, which is called a pipe pass; the other fluid enters from a connecting pipe of the shell and flows out from the other connecting pipe on the shell, and the other fluid is called shell side.
After the heat exchanger was used for a long time, because there are magnesium ion and calcium ion in the aquatic, through the heating, the carbonate crystallization of the calcium that is called the incrustation scale or magnesium is attached to the surface of heat exchange tube to influence heat transfer efficiency, need carry out the scale removal operation after a period, current heat exchanger scale removal mode need be dismantled the shell, wastes time and energy, and scale removal efficiency is lower, so need the design of improving of pertinence.
Disclosure of Invention
The invention aims to provide a shell and tube heat exchanger scale removing device which is put into use and solves the problems in the background technology.
In order to achieve the purpose, the invention provides the following technical scheme: the utility model provides a shell and tube heat exchanger incrustation scale clearing device, includes the heat exchanger shell, the heat exchanger shell is fitted with a contraceptive ring and is equipped with many pipelines, set up the strip seam with heat exchanger inner chamber intercommunication on the pipeline lateral wall, the pipe support passes through the ring canal intercommunication, but the inside including the heat exchanger shell is provided with lateral sliding's plastic slab, be provided with the polylith around the plastic slab and insert the inboard ear of pipeline, the heat exchange tube in the heat exchanger shell runs through the plastic slab.
Preferably, the plastic plate is axially and fixedly provided with a plurality of supporting tubes, the supporting tubes are sleeved outside the heat exchange tube, scraping teeth are arranged on the inner wall of each supporting tube, and the end parts of the scraping teeth are abutted against the outer wall of the heat exchange tube.
Preferably, the length of the support tube is greater than the thickness of the plastic plate.
Preferably, the length of the support tube is 3 to 5 times the thickness of the plastic plate.
Preferably, the ear part is fixedly connected with the plastic plate by a metal strip passing through the strip seam.
The invention has the technical effects and advantages that: this tubular heat exchanger incrustation scale clearing device lets in sodium bicarbonate aqueous solution in to the pipeline through the ring canal, and the ear that promotes the plastic slab through the water pressure of aqueous solution moves along the pipeline to promote the plastic slab to slide along the heat exchange tube, cut and rub the outer wall of heat exchange tube, sodium bicarbonate aqueous solution enters into the heat exchanger shell through the crack simultaneously, with incrustation scale contact reaction, get rid of the incrustation scale, destroy incrustation scale surface structure through cutting and rubbing for the infiltration of sodium bicarbonate aqueous solution to the incrustation scale, thereby accelerate the incrustation scale reaction, it is better to get rid of the effect, and the practicality is stronger.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention provides a shell and tube heat exchanger scale removing device as shown in figures 1-3, which comprises a heat exchanger shell 1, wherein a plurality of pipelines 2 are annularly arranged on the heat exchanger shell 1, the side walls of the pipelines 2 are provided with strip seams 3 communicated with the inner cavity of a heat exchanger, the supports of the pipelines 2 are communicated through a ring pipe 4, a plastic plate 5 capable of sliding transversely is arranged in the heat exchanger shell 1, a plurality of lugs 6 inserted into the inner side of the pipelines 2 are arranged on the periphery of the plastic plate 5, and heat exchange tubes 7 in the heat exchanger shell 1 penetrate through the plastic plate 5.
When scale removal operation is needed, sodium bicarbonate aqueous solution is introduced into the pipeline 2 through the ring pipe 4, the ear part 6 of the plastic plate 5 is pushed to move along the pipeline 2 through the water pressure of the aqueous solution, so that the plastic plate 5 is pushed to slide along the heat exchange pipe 7, the outer wall of the heat exchange pipe 7 is cut and rubbed, meanwhile, the sodium bicarbonate aqueous solution enters the heat exchanger shell 1 through the strip seam 3, is in contact reaction with the scale, the scale is removed, the surface structure of the scale is damaged through cutting, the permeation of the sodium bicarbonate aqueous solution to the scale is accelerated, the scale reaction is accelerated, the removal effect is better, and the practicability is stronger.
A plurality of supporting tubes 8 are axially and fixedly arranged on the plastic plate 5, the supporting tubes 8 are sleeved outside the heat exchange tube 7, scraping teeth 9 are arranged on the inner wall of each supporting tube 8, and the end parts of the scraping teeth 9 are pressed against the outer wall of the heat exchange tube 7. Through the arrangement of the supporting tube 8 and the scraping teeth 9, the pressure on the surface of the scale is enhanced, the friction force between the plastic plate and the heat exchange tube 7 is reduced, and the plastic plate 5 is ensured to slide more smoothly along the heat exchange tube 7.
The length of the support tube 8 is greater than the thickness of the plastic plate 5. The tilting is avoided in the case of uneven stressing of the plastic plate 5.
The length of the support tube 8 is 3-5 times the thickness of the plastic plate 5. The situation that the supporting tube 8 is too short to cause uneven stress on the plastic plate 5 and incline or the situation that the friction force is too large and the sliding is not smooth is avoided.
The ear parts 6 are fixedly connected with the plastic plate 5 through metal strips 10 passing through the strip seams 3. The joint strength between reinforcing plastic slab 5 and the ear 6 avoids because the great condition that causes fracture between ear 6 and the plastic slab 5 of water pressure, guarantees life.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
