Abstract

PURPOSE:To provide the cleaning body collecting device which enable to reduce the extracting flow rate by avoiding the generation of stagnating area. CONSTITUTION:The titled device is composed of a lattice 4, components 1A, 1B and 2A, 2B. A cleaning body S which is rolled on said lattice 4 is flowed on said components 1A, 1B with the water flow, flowed down by the inclination of said components. In this case, a part of the water flow is flowed out toward lower stream side from a slit 11 having the width narrower than the space between said each lattice. Thereby, the generation of stagnating area on the gutter upper stream is prevented, and flowing of the cleaning body into components 2A, 2B is facilitated. In said component 2A, 2B, a part of the water flow is flowed out toward outside of the wall by several slits 12 having the width narrower than the space between said each lattice, and a cleaning body S is facilitated to be flowed into a extracting pipe 3, accordingly, the flow rate which is extracted from said extracting pipe 3 can be reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cleaning body collection for cleaning a tubular heat exchanger, which collects the cleaning body after washing heat transfer by putting the cleaning body into the cooling water of the tubular heat exchanger. Concerning a collection device.

In the conventional cleaning body collecting device, as shown in FIGS. 1 and 2, the cleaning body S rolls on the upper surface of the nematode collection Yuko 4, and the cleaning body S is placed on the center line that divides the body into two, and is connected to the extraction pipe 3. The member LA that forms the gutter that waits for a certain slope.

If a plurality of members IA and IB are arranged, which flow onto 1B, a pair of parts is provided. The cleaning body S is collected by the members 2A and 2B and extracted to the outside of the body from the extraction pipe 3. Therefore, the member I
In the upstream parts of A, IB, 2A, and 2B, it is necessary to let all of the inflowing water flow down, and when the extracted water type decreases, a stagnation area occurs in the upstream parts of the parts, making it difficult to recover the washed body. Therefore, it is necessary to increase the amount of extracted water, which has the disadvantage of increasing the equipment price and operating cost due to the increased pump capacity.

SUMMARY OF THE INVENTION An object of the present invention is to provide a cleaning body collecting device that allows extraction current to be reduced by t-m when a stagnation area occurs.

The anti-PP trapping device of the present invention is characterized by having a structure in which slits are provided on the wall surfaces of the members and between the paired members through which part of the water flows out to the downstream side, thereby preventing the generation of stagnation areas.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a solid body collection device according to an embodiment of the present invention will be explained with reference to FIGS. 3 and 4.

In the figure, the main configuration a grid 41 members IA and I of the present invention are shown.
The cleaning bodies B, 2A, and 2B, which have been rolling on the grid 4, flow together with the water flow onto the members IA and IB forming the gutter, and flow down due to the slope. In the members 2A and 2B, the slits 12 with a width equal to or less than the lattice spacing are used to prevent the occurrence of a stagnation area upstream of the gutter and facilitate the flow into the members 2A and 2B. In this embodiment, a bath shaft (not shown) is used to flow a part of the water flow out of the wall to facilitate the flow of the cleaning body S into the extraction pipe 3, thereby reducing the flow rate extracted from the extraction g3. Even if the foreign matter living in the cold water is layered on the slit 12, the outer surfaces of 2A and 2B are the same on the upstream side, so the water flow passing through the slit 127 is the same. It has the effect of reversing the flow and causing foreign matter to flow down.

According to the present invention, since the generation of stagnation areas can be avoided, the amount of extracted water can be reduced.
