A built-in and detachable filter for plate heat exchanger

Abstract

The present invention relates to a removable filter for a plate heat exchanger, comprising a front filter, a rear filter, and a removable blind plate. The front and rear filters are installed within the seawater inlet channel of the plate heat exchanger and sealed by the seawater pipe and the removable blind plate. The removable filter enables filtering on the seawater side of a marine plate heat exchanger. It also saves space in the seawater filter, optimizing its internal placement within the equipment and reducing its size.

Description

Technical Field

[0001] The invention relates to a marine heat exchanger, in particular to a built-in and detachable filter for a plate-type heat exchanger. Background Art

[0002] In the current field of marine heat exchangers, seawater plate cooling devices all require the installation of seawater filters at the seawater inlet. This operation method takes up a lot of space in front of the heat exchanger and makes it difficult to arrange the equipment compactly.

[0003] Therefore, there is an urgent need to solve the current problem of marine plate heat exchangers being clogged by seawater after long-term operation and the seawater filter occupying site space. This will not only allow the seawater side of the marine plate heat exchanger to be cleaned in a timely manner after being clogged, but also optimize the space occupied by the pipeline on site. Summary of the Invention

[0004] In order to solve the problems that the seawater in the current marine plate heat exchanger becomes dirty and clogged after long-term operation and the seawater filter occupies site space, the present invention provides a built-in and detachable filter for the plate heat exchanger.

[0005] To achieve the above objectives, the technical solution of the present invention is: a built-in and detachable filter for a plate heat exchanger, including a front built-in filter, a rear built-in filter, and a detachable blind plate. The front built-in filter and the rear built-in filter are installed in the seawater inlet channel of the plate heat exchanger and are sealed by the seawater pipe and the detachable blind plate.

[0006] Furthermore, the front built-in filter is fixed at the seawater inlet of the plate heat exchanger to play a filtering and sealing role.

[0007] Furthermore, one end of the rear built-in filter is connected to the front built-in filter, and the other end is connected to the disassembly blind plate.

[0008] Furthermore, the detachable blind plate is detachably connected to the plate heat exchanger.

[0009] Furthermore, when the seawater is dirty and blocked, the seawater is disconnected, the disassembly blind plate is opened and the rear built-in filter is pulled out for cleaning, while the front built-in filter remains in place. After the rear built-in filter is cleaned, it is reinstalled and the disassembly blind plate is tightened.

[0010] The beneficial effects of the present invention are:

[0011] 1. The use of a built-in detachable plate heat exchanger filter can enable the seawater side of the marine plate heat exchanger to achieve the filtering function.

[0012] 2. The use of a built-in detachable plate heat exchanger filter can save space for the seawater filter, optimize it inside the equipment, and reduce its size. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1It is a schematic diagram of the built-in and detachable filter for plate heat exchanger of the present invention. DETAILED DESCRIPTION

[0014] In order to better understand the technical solution of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments.

[0015] like Figure 1 As shown, a removable filter for a plate heat exchanger according to an embodiment of the present invention includes: a seawater pipeline 1, a front built-in filter 2, a rear built-in filter 3, a removable blind plate 4, and a plate heat exchanger 5. The seawater pipeline 1, the front built-in filter 2, the rear built-in filter 3, and the plate heat exchanger 5 are sequentially connected to form a seawater filtration device for a plate heat exchanger.

[0016] The built-in and detachable filter for plate heat exchangers can not only clean the seawater side of the marine plate heat exchanger in time after being blocked, but also optimize the space occupied by pipelines on site.

[0017] The seawater filtering device of the plate heat exchanger 5 is realized by a combination of a front built-in filter 2 and a rear built-in filter 3. The front built-in filter 2 is fixed at the seawater inlet of the plate heat exchanger 5 to play a filtering and sealing role. The rear built-in filter 3 can be taken out from the disassembly blind plate 4 to collect garbage. When the seawater is dirty and blocked, the seawater is disconnected, the disassembly blind plate 4 is opened, and the rear built-in filter 3 is pulled out for cleaning. The front built-in filter 2 remains in its original place. After cleaning, the rear built-in filter 3 is reinstalled and the disassembly blind plate 4 is tightened.

[0018] When the seawater side is clogged again, the previous operation is repeated to repeatedly clean the rear built-in filter 3.
