Problems solved by technology

[0003] The land-based test simulators established abroad mainly have the following four shortcomings: (1) In order to meet the test requirements, the cost of rebuilding old ships is high, and ships berthing at the wharf need to pay regular fees related to berth leasing, and the test cost is high; (2) ) Vessels berth at the wharf for a long time, which is greatly affected by the weather, which is not conducive to the stable development of the test; (3) There are many equipment in the engine room of the old ship, which poses a safety hazard to the experimenters; (4) The reuse of the old ship after transformation less likely
[0004] At present, there is no report on the design method of the land-based test simulation device for the ship's ballast water treatment system

Embodiment 1

[0020] Embodiment 1: see image 3 , first add 600kg of sea salt, 10L of heterotrophic bacteria, green algae, 2kg of glucose-chitosan, and sea mud to 4-cultivation cabin 1 and 5-culture cabin 2, and the test salt water reaches the salinity of G8 guidelines > 32PSU, etc. The various index requirements, and with 250m 3The flow rate of / h injects the ballast water in the cultivation cabin from the ballast pump through the opened valves V2, V3, V4, V6,, V7, V14, V15 into the treatment cabin, through the opened valves V1, V2, V3, V8, V9 was injected into the comparison cabin, and samples were taken at N1, N2, and N3 respectively. After the ballast water was stored in the treatment cabin and the comparison cabin for 5 days, it was discharged with a pump, and samples were taken at N1. The samples obtained from the three places were tested for seawater parameters, microorganisms, plankton, active substances and related chemical substances and toxicity tests.

Embodiment 2

[0021] Embodiment 2: see Figure 4 First add 70m of tap water to 4-cultivation cabin 1 and 5-culture cabin 2 respectively 3 , heterotrophic bacteria 20L, green algae, glucose 0.5kg, chitosan 7kg, sea mud 20kg, the test salt water meets the requirements of various indicators such as salinity 3-32PSU in the G8 guideline, and the 300m 3 The flow rate of / h injects the ballast water in the cultivation cabin from the ballast pump through the opened valves V2, V3, V4, V6,, V7, V14, V15 into the treatment cabin, through the opened valves V1, V2, V3, V8, V9 was injected into the comparison cabin, and samples were taken at N1, N2, and N3 respectively.

Abstract

The invention relates to a device for simulating a land-based test of a ship ballast water treatment system, which relates to the field of ships. The device consists of a comparison cabin (1), a processing cabin (2), an operating room (3), a first culture cabin (4), a second culture cabin (5), a cement bearing platform (6), a first UPVC connecting pipeline (7), a second UPVC connecting pipeline (8), a ballast pump inlet (9), a ballast pump outlet (10), a control valve (11), a third UPVC connecting pipeline (12), a fourth UPVC connecting pipeline (13), a sampling point (14) and a fifth UPVC connecting pipeline (15). The device can meet test requirements of a G8 guideline of 'Approved Guidelines for Ballast Water Treatment System'; besides, the flow speed of ballast water is between 250 and 300m3 / h, and the complete set of the device runs normally.

Description

Technical field: [0001] The invention relates to the field of ships, in particular to a land-based test device for a ship's ballast water treatment system. Background technique: [0002] In order to effectively prevent the invasion of alien species caused by ships' ballast water, in 2004, the International Maritime Organization (IMO) passed the International Convention for the Control and Management of Ships' Ballast Water and Sediments. The "Convention" stipulates that according to the different ballast water volumes, from 2009, some new ships must be installed with ballast water treatment systems, and retrospectively implemented on existing ships. By 2017, all ocean-going ships must be installed with ballast water treatment equipment. ; and it is stipulated that the ballast water treatment system on board must pass the land-based test type approval. [0003] The land-based test simulators established abroad mainly have the following four shortcomings: (1) In order to meet...
