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.
