In an open rack type vaporizer, for example, a pair of fins protruding in the diametrical direction is arranged in a single panel shape, with a pair of fins protruding in the diametrical direction, and header tanks are provided at the upper and lower ends of the panel to form a heat exchange panel. , a structure in which a plurality of such panels are arranged in parallel, and seawater as a heat medium flows down onto the surface of the heat exchange panel from a water sprinkler disposed above each panel.

Seawater is used as a heat medium in a vaporizer mainly for economical reasons, but conventionally, water sprinklers have box-shaped troughs with open tops installed opposite each other on both sides of the top of a heat exchange panel. However, the seawater is configured to flow into the trough from a water spray nozzle located on the open surface of the trough, and overflow from the overflow edge on the heat exchange panel side of the trough.

In addition, the water spray nozzle is configured to supply seawater by branching from a water supply pipe placed above the trough, and the ripples of seawater falling from the water spray nozzle are
A partition plate is placed inside the trough to prevent overflow from flowing from the overflow edge.

Since such watering devices use seawater, marine organisms such as algae and shellfish may adhere to and grow within the trough, which may obstruct the flow of water within the trough, or cause grown shellfish to flow downstream. The problem is that the seawater gets caught between the overflow edge and the heat exchange panel, preventing the seawater from falling in the same area, causing the seawater flowing along the heat exchange panel to be interrupted, preventing vaporization from proceeding, and exposing the area to local stress. It was hot.

For this reason, conventional efforts have been made to improve the shape and arrangement of the partition plates inside the trough, but these are not sufficient.
Seawater is treated with chemicals to prevent marine organisms from adhering to it, but this has created a new problem in wastewater treatment.

Purpose of the invention In view of the above-mentioned current situation, this invention was developed to prevent marine organisms from adhering to the water sprinkler system of an open rack type vaporizer without chemically treating seawater or complicating the configuration of the water sprinkler system. The aim is to construct a water sprinkler system that is extremely effective in preventing marine organisms from adhering to it.

Structure and Effects of the Idea This idea consists of a heat exchange panel consisting of a series of finch tubes and header tanks installed at the top and bottom ends, with the overflow edge of the trough having an open top facing the heat exchange panel.
A water sprinkling device for an open rack type vaporizer that overflows seawater from the trough and sprinkles water on a heat exchange panel, comprising: a pair of ripple prevention partition plates disposed in the trough with water nozzles sandwiched therebetween; At least one hole is formed in the bottom of the trough between the holes, and the hole diameter is variable and can be opened and closed.
This is an open rack type vaporizer water sprinkling device characterized by having several drains for preventing the accumulation of marine organisms.

In other words, in the sprinkler system of this invention, the amount of water overflowing from the trough is prevented from fluctuating by the partition plates for preventing ripples, but a stagnant area of seawater occurs near the bottom of the trough between the partition plates, which can cause damage to marine life. This is an area where larvae can easily attach and grow, so by installing a drain in the above-mentioned specific position, the seawater in the stagnation area at the bottom of the trough will not stagnate and will flow towards the drain, thereby preventing marine creature larvae, etc. It has the function of discharging it outside the trough.

Therefore, the drain for preventing the accumulation of marine life according to this invention has a drainage capacity that does not reduce the amount of water overflowing from the trough more than necessary, and the drain can be closed and opened with a rubber plug, etc. Furthermore, as shown in the example, one synthetic resin plug is concentrically divided into multiple plugs with different diameters, and the opening diameter is made variable so that the discharge amount can be set depending on the diameter of the plug to be opened. By using a drain, a part of the seawater can be constantly drained from the bottom of the trough by opening the drain of the required plug diameter during the breeding season of marine life, and the marine life staying near the bottom of the trough can be removed from the trough. It has the advantage of being able to be discharged to

Therefore, it is preferable for a drain to prevent the accumulation of marine organisms to have a drainage amount that causes seawater to move toward the drain without causing it to accumulate at the bottom of the trough, and the opening location and opening diameter of the drain also depend on the configuration and shape of the trough. It is desirable to set the trough bottom at a location that is effective for promoting fluidization of seawater, depending on the dimensions, etc.
