Scrubber apparatus having integrated venturi

Abstract

The present invention relates to a scrubber apparatus that is for removing harmful substances and is installed in an engine exhaust line, the scrubber apparatus comprising: a scrubber main body provided with a gas inlet and a gas outlet and providing a main flow channel through which an exhaust gas can move; a plurality of collection layers installed spaced apart from each other in the scrubber main body; a venturi unit installed inside the lower portion of the scrubber main body and having at least one venturi conduit formed therein through which the exhaust gas can pass; and multiple cleaning-water spraying pipes installed along the movement path of the exhaust gas and multiply-spraying cleaning water in the forward direction of the exhaust gas, and thus the scrubber apparatus having anintegrated venturi is not only simple to install and disassemble due to the minimized size, weight, etc., of the scrubber apparatus, but also has excellent space utilization and expandability.

Description

technical field [0001] The present invention relates to a scrubber for trapping and removing harmful substances contained in the exhaust gas of a ship engine, and more specifically, to a Venturi-integrated scrubber in which a Venturi structure is integrated inside a scrubber body, and at the same time, The scrubber body can be installed or disassembled in multiple stages, thereby reducing the overall size, volume, and weight of the scrubber, improving portability, installation, and space utilization, and can be effectively applied to marine engines of various sizes. Background technique [0002] Generally, in order to propel a ship, a main engine for driving a propeller and a plurality of generator engines for supplying power to various devices and equipment mounted on the ship are provided and operated. [0003] Exhaust gas discharged after combustion in diesel engines of such ships contains not only many suspended particulates such as dust and fine dust, but also many harm...

AI Technical Summary

Problems solved by technology

[0019] First, the Venturi that can diffuse and expand the exhaust gas is separately installed outside the scrubber body, which increases the size, volume, or weight of the overall scrubber. Therefore, the installation cost and time are significantly increased. Features, space (space) is insufficient, so there are many constraints when securing space for installation

[0020] Second, the scrubber body is manufactured with an integrated cylindrical structure for transportation and installation. Due to the characteristics of a high-weight marine engine scrubber of about 30 tons, the handling or installation performance is significantly reduced, and maintenance costs are also increased.

[0021] Third, due to the structural characteristics of the cylindrical Venturi, the scale caused by changes in the temperature, flow rate, and moisture content of the exhaust gas or the particle size distribution and density of the particulate matter to be removed, etc. , so that the Venturi hole (hole) is easily blocked, thereby reducing the stability of navigation

[0022] Fourth, when the amount of exhaust gas to be treated increases, it is difficult to expand the pipe of the cylindrical venturi. Therefore, it is necessary to replace the venturi with a larger capacity or to install an additional venturi, which increases the manufacturing cost, and, Doesn't work well with engines of all sizes

[0023] Fifth, due to the structural interference of internal materials such as the packing of the scrubber and the demister (Demister) and the washing water sprayed in the opposite direction of the moving direction of the exhaust gas, the exhaust gas moving inside the scrubber body is subjected to back pressure, thereby, Side effects such as increased load on the main engine, decreased output, etc.

[0024] In order to prevent such back pressure, conventionally, an additional forced draft fan has been installed to compensate for it. In this case, it is necessary to bear the installation cost due to the additional blower and the increase in operating cost due to the additional power consumption.
