Embodiment Construction
[0028] The present invention will be further described by way of examples below, but the present invention is not limited to the scope of the examples. In the following examples, the experimental methods without specific conditions are selected according to conventional methods and conditions, or according to the product specification.
[0029] Such as Figure 1-Figure 4 As shown, this embodiment discloses a method for installing an SCR denitration reactor, wherein, as Figure 4 As shown, the installation method of the SCR denitration reactor of this embodiment includes the following steps:
[0030] Step S1, a process hole 22 is opened on the bulkhead of the engine room 2 of the ship, so that the engine room 2 of the ship and the cargo hold 1 are spatially connected;
[0031] Step S2, hoist the SCR denitration reactor 3 from the hatch 11 of the cargo hold 1 into the cargo hold 1;
[0032] Step S3, hoist the SCR denitration reactor 3 to the position of the process hole 22;
[0033] Step...

The invention discloses an SCR denitration reactor mounting method and a ship mounted by using same. The SCR denitration reactor mounting method comprises the following steps of step 1, forming a process hole in the wall of an engine room of the ship so that the engine room of the ship communicates with a cargo compartment in the space; step S2, hoisting an SCR denitration reactor into the cargo compartment from a hatchway of the cargo compartment; step S3, hoisting the SCR denitration reactor into the position of the process hole; step S4, moving the SCR denitration reactor into the engine compartment from the process hole; and step S5, mounting the SCR denitration reactor into the engine compartment. According to the SCR denitration reactor mounting method, the SCR denitration reactor enters the engine compartment to be mounted from the hatchway of the cargo compartment and the process hole so that the SCR denitration reactor is mounted after the engine compartment is sealed. Therefore, the choosability of the mounting opportunity of the SCR denitration reactor is greatly enhanced.
Description
Technical field [0001] The invention relates to a method for installing an SCR denitration reactor and a ship installed by using the method. Background technique [0002] In order to meet the requirements of the International Maritime Organization for the emission of nitrogen oxides and sulfides from marine main engines, marine main engines need to add SCR (Selective Catalytic Reduction) denitrification reactor devices, and the first ship SCR device must be installed in the factory along with the main engine. Do the experiment, the delivery period is the same as the host. [0003] The SCR device is arranged on the third deck of the engine room, so the SCR denitration reactor must be transported and installed in advance. However, SCR denitrification reactors are generally purchased from outside. If the main engine is purchased to the factory at a later date, the ship hull structure has basically completed docking operations except for the construction of the ship and the engine roo...
