A spraying device for degreaser

Abstract

The invention provides an oil dispersant spraying device, which comprises an upright post and a transverse arm, wherein the upright post consists of a rotary joint inner ring, a rotary joint outer ring and a davit; the rotary joint inner ring is arranged on a deck and connected with an oil dispersant pipeline; the rotary joint outer ring is arranged outside the rotary joint inner ring in a sleeving manner and placed at the upper end of the rotary joint inner ring; the davit is arranged at the upper end of the rotary joint outer ring; a lug plate is arranged on the outer wall of the davit; the transverse arm is a hollow pipe of which the inner diameter is reduced progressively from one end near the upright post to the other end far away from the upright post; one end of the transverse arm is communicated with the rotary joint outer ring; a plurality of nozzles are arranged on the hollow pipe; a lifting lug is arranged on the outer wall, opposite to the nozzles, of the hollow pipe; and the lifting lug is connected with the lug plate through a steel wire rope. The oil dispersant spraying device enhances the strength of the deck; a rubber pipe is replaced by a steel pipe, so maintenance or ageing and replacement is avoided; the transverse arm adopts reducing through pipe connection, so the spraying effect of the oil dispersant is guaranteed; each nozzle consists of a spray head cover and a spray pipe, so the spraying radiation range can be adjusted; and the pipe diameter is large, the pipe wall is thick and the service life is long.

Description

technical field [0001] The invention relates to the field of ship deck machinery, in particular to a dispersant spraying device. Background technique [0002] With the development of offshore oil, the oil pollution caused by oil leakage during the exploitation process and the grounding of oil tankers is becoming more and more serious. In order to protect the ecological environment of lakes and oceans, all kinds of engineering ships are equipped with oil dispersing or oil collecting devices. Such as figure 1 The oil dispersant spraying device shown is a long cross-arm spraying device, the cross arm 5 is supported by a column 30, and is pulled on the top of the column 30 by a steel cable 31. When in use, the entire oil dispersant spraying device passes through the column 30 welded to the deck. Dispersant is delivered in the pipeline of cross arm 5 through flexible pipe 32 by the pipeline under deck, is sprayed out by the nozzle 6 on the cross arm 5. The oil dispersing devi...

Problems solved by technology

[0003] The purpose of the present invention is to improve the existing dispersant spraying device, overcome its weakened deck strength, long-term exposure causes hose aging, and the single inner diameter of the cross-arm pipeline makes the end pressure small, making the spraying effect unsatisfactory and unable to cover a large area Defects of the oil spill
