Technical Field
The utility model relates to a boats and ships exhaust gas desulfurization technical field, more specifically say, relate to a quick drainage system suitable for boats and ships desulfurization.
Background
In order to reduce SO in the ship tail gas2The impact on atmospheric environment was determined by the IMO 70 th conference on the marine environmental protection commission, which imposed a higher standard for sulfur content from 1/2020, i.e. the global fuel oil sulfur content should not exceed 0.5% and the european Emission Control Area (ECA) should not exceed 0.1%. There are three current approaches to fulfilling the IMO requirements for sulfur emissions: low-sulfur fuel oil, Liquefied Natural Gas (LNG) and ship exhaust gas desulfurization technology (device). In the aspect of ship exhaust gas desulfurization technology, corrosion prevention requirements are considered, GRE pipes are generally adopted in a drainage system, and bidirectional stainless steel is also considered. The drainage pipeline is usually directly connected with the bottom of the washing tower, and the horizontal section is designed to be inclined, so that the washing water can flow out more easily. Finally, the qualified water quality is discharged out of the ship through a plurality of ship board discharging pipes and enters the shipSea water. Because the drainage pipe does not set up the discharge pump, is a gravity flow system, actual operation discovery has often during boats and ships waste gas enters into drainage pipe, not only has the risk that arouses the pipeline surge, has seriously influenced the speed of drainage moreover, makes the risk aggravation of the inside liquid level rising of scrubbing tower, has directly influenced the steady operation of system.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a quick drainage system suitable for boats and ships desulfurization, this system is rational in infrastructure, and it is convenient to implement, can reach better drainage effect, can effectively be applicable to the boats and ships desulfurization system of any open or mixed method.
In order to realize the purpose, the utility model discloses a technical scheme as follows:
the utility model provides a quick drainage system suitable for boats and ships desulfurization, drainage system install in scrubbing tower body below, drainage system include gas-insulated hourglass fill, reducing reducer, drain pipe and row's board pipe, gas-insulated hourglass fill set up inside scrubbing tower body below outlet, gas-insulated hourglass fill through the external drain pipe of outside reducing reducer, drain pipe one end and gas-insulated hourglass fill intercommunication and other end connection row's board pipe, gas-insulated hourglass fill constitute by gas barrier plate and a plurality of reposition of redundant personnel baffle, wherein the reposition of redundant personnel baffle all encircles central gas barrier plate equidistance vertical arrangement and with gas barrier plate fixed connection all around, reposition of redundant personnel baffle below inclination and scrubbing tower body bottom conic section gradient cooperate.
Furthermore, the horizontal section of the drain pipe is directly and horizontally installed without a placing slope.
Furthermore, the ship board discharging pipe is not provided with a slope and is directly and horizontally discharged outboard to be installed and matched with the ship board.
Furthermore, a guide plate is arranged inside the exhaust pipe.
Furthermore, the diameter of the air baffle is 1.1-1.3 times of that of the bottom pipe orifice, and the length of the flow dividing partition plate is 1/5-1/4 of that of the bottom conical section.
Compared with the prior art, the utility model has the advantages that:
1. the drainage system is more stable and faster. Compared with the gravity flow drainage system in the prior art, the washing wastewater is discharged by the drainage system for full pipe flow, the discharge is stable and quick, no smoke enters the drainage pipeline, and the risk of pipeline surge is avoided.
2. Effectively reduce the drain pipe diameter, more conveniently arrange the installation. Due to the narrow space of the ship, the arrangement of the drainage pipeline is quite difficult, and the cabin needs to be penetrated frequently, so that the construction difficulty is very high. The smaller the diameter of the pipeline is, the easier and more cost-effective the construction is. Compared with the current mainstream technology, the system has the advantages that the drainage speed is effectively increased, the diameter of the pipeline under the same drainage quantity is smaller, and the arrangement and installation of the field pipeline are very facilitated.
3. The horizontal section of the drainage pipeline does not need to be subjected to slope relief. Compared with the gravity flow drainage in the prior art which needs arranging a placing slope, the invention utilizes the siphon drainage principle, and the horizontal section of the pipeline does not need to be placed on the slope. Practical engineering also finds that the diameter of a drainage pipeline is generally large, the slope arrangement is difficult to control in construction, and the arrangement deviation influences the drainage effect. The invention can effectively solve the problem, is more convenient to construct and has little influence on a drainage system.
