Inlet flow mixing pipe of desulfurizing tower

Abstract

The invention relates to an inlet flow mixing pipe of a desulfurizing tower. The inlet flow mixing pipe comprises a bottom sealing plate and a connecting plate located above the bottom sealing plate,wherein the bottom sealing plate and the connecting plate are connected into a whole through a peripheral plate, the bottom sealing plate, the connecting plate and the peripheral plate define an internal space allowing waste gas to be exhausted into, a powder generator air inlet hole, a host machine air inlet hole and a boiler air inlet hole are formed in the bottom sealing plate, an air outlet hole is formed in the connecting plate, air inlet pipes are arranged at the power generator air inlet hole, the host machine air inlet hole and the boiler air inlet hole, an air outlet pipe is arrangedat the air outlet hole, and the center of the host machine air inlet hole, the center of the air inlet pipe arranged at the host machine air inlet hole, the center of the air outlet hole in the connecting plate and the center of the air outlet pipe are located on the same straight line. The inlet flow mixing pipe of the desulfurizing tower is small in back pressure, stable in air discharge, smallin occupied space and simple in structure.

Description

technical field [0001] The invention relates to an inlet mixed flow pipe of a desulfurization tower on a ship. Background technique [0002] With the implementation of the MARPOL Convention, more and more ships have installed desulfurization towers to reduce the emission of sulfide in the exhaust gas in recent years. It is difficult to realize the confluence of main engine, generator and boiler exhaust gas to the intake pipe inlet of the desulfurization tower in the limited space of the pipe. In the industry, branch pipes are usually installed on a main pipe connected to the intake pipe of the desulfurization tower, and the main engine exhaust pipe, generator exhaust pipe and boiler exhaust pipe are respectively connected to the corresponding branch pipes so that the exhaust gas can flow into the main pipe In the process, it is discharged from the main pipe into the intake pipe of the desulfurization tower. Because there are many branch pipes, it occupies a large space, and...

Problems solved by technology

In the industry, branch pipes are usually installed on a main pipe connected to the intake pipe of the desulfurization tower, and the main engine exhaust pipe, generator exhaust pipe and boiler exhaust pipe are respectively connected to the corresponding branch pipes so that the exhaust gas can flow into the main pipe In the process, it is discharged from the main pipe into the intake pipe of the desulfurization tower. Because there are many branch pipes, it occupies a large space, and the branch pipes are arranged in a complicated way when they enter the main pipe, which will generate a large back pressure on the exhaust gas and affect the main engine. and the generator works normally
