Description

In-line filter for plate heat exchanger and installation method {IN-LINE FILTER USED FOR PLATE HEAT EXCHANGER AND POSITIONING METHOD THEREOF}

The present invention relates to an inline filter mounted inside the cooling water inlet of a plate heat exchanger and a method of installing the same, and there is no fear of inconvenience caused by rolling the perforated plate and corrosion of the welded portion, and easy to install and disassemble. The present invention relates to an inline filter and a method for installing the same, which can be prevented from being deformed by being closely attached between the inline filter and the heat transfer plate.

In general, a plate heat exchanger superimposes a plurality of formed metal plates in consideration of the type and flow of a fluid, structural strength of a product, and alternately flows a heating fluid and a hydrothermal fluid between layers to prevent heat exchange of a fluid passing between the metal plates. It is a device to make it.

In this case, examples of the heating fluid include high temperature fluids such as high temperature water, steam, and lubricating oil. Examples of hydrothermal fluids include fluids that are relatively lower than high temperature fluids such as water, sea water, and refrigerant.

That is, two types of fluids having different temperatures are separated by the interlayer flow path between the metal plates and flow in a counter flow. The heat exchange is performed while the high and low temperature fluids intersect one by one.

Plate heat exchangers are widely used as cooling and heating devices for various boiler facilities, wastewater treatment facilities, dyeing facilities, power plants, ships, incinerators, etc. due to their small size, light weight, and high efficiency.

Hereinafter, a conventional plate heat exchanger will be described with reference to FIGS. 1 and 2.

When foreign matter is included in the heating fluid or the hydrothermal fluid circulating through the heat transfer path formed in the heat transfer plate 11, the heat transfer path is blocked by the foreign matter, which may cause a negative effect of decreasing the thermal efficiency of the heat exchanger and increasing the pressure loss. Since the cooling water inlet 13 may be provided with an inline filter 20 for filtering foreign substances, the inline filter 20 may be formed of a SUS having a plurality of perforation holes 21 as shown in FIG. 1. It is composed of a cylindrical body 23 rolling a rectangular perforated plate made of stainless material, and a flange portion 25 formed at the distal end of the body 23.

There is a problem.

Second, when the cooling water is sea water, since the process of forming the inline filter 20 into a cylindrical body is joined by welding, the welding part is corroded by sea water and the pressure of the cooling water is increased for a long time as the pressure of the cooling water increases. There is a problem in that the acceleration and corrosion of the weld site occurs.

Third, when the plate heat exchanger 10 is installed for cooling purposes of the marine marine engine, if the inline filter 20 is broken during operation of the ship, there is a difficulty of airborne replacement, especially the inline filter 20 Is formed as one main body 23, at least a space corresponding to the length of the inline filter 20 is required in order to replace the inline filter 20, since the machine room space of the ship is generally narrow, the inline filter 20 There is a problem that is very difficult to disassemble and replace.

Fourth, although the rivet was used to replace the welding of the inline filter 20, since the inline filter 20 is installed at a predetermined distance away from the surface generated by the heat transfer plate 11, the rivet is corroded or Alternatively, there is a problem of being damaged by the inlet pressure of the coolant to fall off and cause a fatal damage to the running equipment.

10 is a flowchart sequentially illustrating a process in which the inline filter 100 according to the present invention is installed in the plate heat exchanger 10.

As shown in FIG. 10, the installation method of the inline filter 100 for the plate heat exchanger 10 is the installation method of the inline filter 100 provided at the inlet 13 of the cooling water formed in the plate heat exchanger 10. In the upper end of the pair of fixing ring 120 is formed by the fixing pin 123 is formed, the lower end of the pair of fastening by the adjusting bolt 133 and the adjusting nut 135 The control bracket 130 is formed, and preparing a rectangular perforated plate 110 formed of a plurality of perforated holes 21 or mesh (S1); Rolling and overlapping the perforated plate 110 to form a cylindrical body 190 (S2); The fixing pin 123 is inserted into the fixing ring 120 to fix the upper side of the main body 190, and the adjusting bolt 133 and the adjusting nut 135 are fastened to the adjusting bracket 130 to the main body 190. Respectively fixing the lower sides of the step (S3); Inserting the main body (190) into the cooling water inlet of the plate heat exchanger (10) and placing it (S4); Removing the fixing pin 123 from the fixing ring 120 to release the upper side of the main body 190 (S5); And step (S6) in close contact with the inside of the cooling water inlet of the plate heat exchanger 10 while unwinding the adjusting bolt 133 and the adjustment nut 135 fastened to the control bracket 130; .

Since the inline filter 100 installed in the plate heat exchanger 10 through the above steps is in close contact with the surface formed by the heat transfer plate 11 of the plate heat exchanger 10, warpage does not occur, and welding is performed. Easy to install and dismantle without maximizing the service life. As the inline filter 100 is decomposed, space utilization according to the installation space is possible.

A pair of fixing loops 120 are formed at both ends of the upper end by fixing pins 123, and a pair of adjusting brackets fastened by the adjusting bolt 133 and the adjusting nut 135 at both ends of the lower end. 130 is formed, and preparing a plurality of perforated holes 21 or rectangular perforated plate 110 formed of a mesh (S1) is a step before forming the cylindrical body 190 of the above inline filter 100. .

First, a rectangular perforated plate 110 having a plurality of perforated holes 21 is prepared.

The perforated hole 21 is in a state penetrating the surface of the perforated plate 110, is formed to be distributed on the entire surface of the perforated plate 110.

At this time, the surface of the perforated plate 110 may be formed of a mesh (mesh) that the fluid flow smoothly, in this case the shape of the mesh may be produced in the shape of the grid and the checkerboard.

At this time, the pair of fixing ring 120 is installed at both ends of the upper perforated plate 110, and is fixed through the fixing pin 123 when the perforated plate 110 is overlapped through the rolling.

In addition, the pair of adjustment brackets 130 are installed at both ends of the lower perforated plate 110, and is fastened by the adjusting bolt 133 and the adjusting nut 135 when the perforated plate 110 is rolled and overlapped. . At this time, the pair of adjustment bracket 130 is preferably formed on a separate in-line band 140 is installed on the inner peripheral surface of the main body 190.

Next, in step S2 of forming the cylindrical body 190 by rolling and overlapping the above perforated plate 110, the prepared perforated plate 110 is formed through a separate rolling molding machine (not shown). ) To form.

First, the rectangular perforated plate 110 prepared as described above is passed through a rolling molding machine (not shown). In this case, the perforated plate 110 is rolled into a cylindrical while passing through a rolling molding machine is overlapped to have a cylindrical shape.

At this time, the pair of fixing ring 120 is installed on the inside of the upper both ends of the perforated plate 110, the state just before facing each other as the above perforated plate 110 does not form a complete cylindrical shape by the overlap to be.

In addition, the in-line band 140 fixed to the upper perforated plate 110 is the same as the shape of the upper body 190 while being rolled along the forming curve with the perforated plate 110 according to the state installed in the lower both ends of the perforated plate 110. Molded into shape. At this time, the pair of adjustment brackets 130 formed on the inline band 140 is in a state facing each other.
