Abstract
The utility model relates to an improve system architecture of ballast water processing system filter capacity, characteristics and the easy situation of blockking up of filter core according to the filter structure, and the present weak link that exists in cleaning function of filter, provide through regulation and control ballast water pipeline pressure, set up the electrical control valve in filter export pipeline, increase a drain pump on filter sewage pipes, make it to satisfy the condition of filter self -cleaning, increase filter pollution discharge effect simultaneously, thereby improve the filter from cleaning capacity, avoid filter blockage, satisfy the requirement that the ballast water injects flow and processing speed into, moreover, the steam generator is simple in structure, the complexity of add -on system not.
Description
Technical field
This utility model relates to marine environmental protection and ballast water for ship processes, the technical field of the raising anti-cleansing power of filter, is specifically related to improve the system structure of ballast water treatment system filter capacity.
Background technology
According to 2004 International Maritime Organization (IMO) formulated the emission request pact of ballast water for ship, boats and ships must be further added by ballast water treatment plant on the basis of original Ballast Management system, makes treated ballast water reach to meet the D-2 discharge standard that pact is formulated. current ballast water treatment system has more than ten kind of method, but every kind of method will arrange filter unit, and filter is made up of (filter element number is determined according to treating capacity) multiple filter elements, and the filter element precision of filter is higher than 50 �� s. owing to ocean and various water pollution are serious in recent years, therefore filter works after a period of time, filter element is easy to blocking, although a lot of filters have self-cleaning function, its anti-Cleaning principle is that filter element is circulated cleaning by (such as 0.3Ba) utilizes ballast water to work when filter inlet outlet pressure differential reaches a threshold value pressure one by one, but due on ship ballast pump general work pressure at about 2-3Bar, so in the poor environment of water quality, after the filter working time is longer, by cleaning the impact that water pressure is gradually lowered, its cleansing power weakens, can not meet ballast water and inject the requirement of flow and processing speed.
Utility model content
For solving the problems referred to above, this a kind of system structure improving ballast water treatment system filter capacity of novel offer, by the control to ballast line flow and pressure, and increase filter pollution discharge capability, reach to improve the anti-cleansing power of filter, solve the practical problem that the anti-cleansing power of filter is not strong.
For realizing object above, by the following technical solutions:
Improve the system structure of ballast water treatment system filter capacity, inlet pipeline connects filter inlet, outlet pipeline takes over the outlet of filter, blow-off line connects filter sewage draining exit, equipped with effusion meter on inlet pipeline, filter being provided with differential pressure switch, filter is connected with control subsystem in system, filter outlet pipe road arranges electric control valve, filter blow-off line increases a draining pump.
Control subsystem in ballast water treatment system is for controlling main body, when flow reduction occurs, when inlet outlet pressure differential continues to increase, control subsystem by the control to electric control valve, change valve opening, improve intake pressure, start the draining pump on blowoff line simultaneously, improve effluent pressure and speed, thus improving the anti-cleansing power of filter.
This utility model benefit effect: improve the discharge dynamics of filter blowoff line, increases the anti-ability cleaned of filter, it is to avoid filter element blocks, and meets ballast water and injects the requirement of flow and processing speed, simple in construction, does not increase the complexity of system.
Accompanying drawing explanation
Fig. 1 is system structure schematic diagram of the present utility model;
As shown in the figure: 1, filter; 2, inlet pipeline; 3, outlet pipeline; 4, effusion meter; 5, differential pressure switch; 6, blow-off line; 7, subsystem is controlled; 8, electric control valve; 9, draining pump.
Detailed description of the invention
Embodiment
Inlet pipeline (2) connects filter (1) entrance, outlet pipeline (3) takes over the outlet of filter (1), blow-off line (6) connects filter (1) sewage draining exit, equipped with effusion meter (4) on inlet pipeline (2), filter (1) is installed differential pressure switch (5), filter (1) is connected with control subsystem (7) in system, arranges electric control valve (8) in filter (1) outlet pipeline (3), filter blow-off line (6) one draining pump (9) of upper increase. During filter (1) normal operation, ballast water is entered filter (1) by entrance pipe (2) by ballast pump, and the impurity that filter (1) will be greater than 50 �� s by filter screen filters, and the water after filtration enters cabin by outlet pipeline (3). When impurity screening is continuously increased, produce to import and export formation pressure reduction, when pressure reduction is higher than, after setting value, being arranged on differential pressure switch (5) Guan Bi on filter (1), starts the anti-of filter (1) and clean. Anti-cleaning the pressure produced in pipeline when relying on ballast pump work, general water quality is better, and when this pressure is more than 2Bar, anti-cleaning can carry out, but when water quality is poor, the working time longer after, backwash ability continues to weaken. When backwash reduced capability, control subsystem (7) will electric control valve (8) in outlet pipeline (3) be regulated and controled, by changing valve opening, improve loine pressure, start the draining pump (9) on blow-off line (6) simultaneously, improve pressure and the speed of blowoff line, so can improve the anti-cleansing power of filter (1). The technology goes for the field that other water filtration processes simultaneously; any it is familiar with these those skilled in the art in the technical scope that this utility model discloses; it is equal to replacement according to the technical solution of the utility model and inventive concept thereof or is changed, all should be encompassed within protection domain of the present utility model.
Claims (1)
1. improve the system structure of ballast water treatment system filter capacity, it is characterized in that, inlet pipeline (2) connects filter (1) entrance, outlet pipeline (3) connects the outlet of filter (1), blow-off line (6) connects filter (1) sewage draining exit, equipped with effusion meter (4) on inlet pipeline (2), filter (1) is provided with differential pressure switch (5), filter (1) is connected with control subsystem (7) in system, filter (1) outlet pipeline (3) arranges electric control valve (8), filter blow-off line (6) one draining pump (9) of upper increase.
