Abstract
The invention relates to a vacuum receiving device for chamber water in an oil stain vessel, which belongs to the field of vessel sewage treatment and environment protection. The vacuum receiving device of chamber water in an oil stain vessel adopts two parallel-connected vacuum diversion canisters. The electronic control unit controls the opening and closing of an electromagnetic valve according to the liquid position signal detected by a level gauge. The compressed air opens the corresponding pneumatic valves for ensuring that another vacuum diversion canister can be opened and drained when one vacuum diversion canister is vacuumized and drew water. The two vacuum diversion canisters can alternately draw water and drain, so the draining work can continuously be carried out. The whole draining process has no mechanical stirring, therefore, a secondary emulsification can be avoided when the chamber bottom water in the transportation process. The vacuum receiving device has the advantages of low investment, energy saving, stable operation with safety and reliability, as well as a high automatic degree and convenient maintenance and management.
Description
Technical field
The present invention relates to a kind of vacuum receiving device of oil-sewage ship bilge water, it belongs to vessel sewage and handles and field of environment protection.
Background technology
The oil of different shape has different physico-chemical properties in the oily(waste)water, has determined the selection of treatment process to a great extent.Usually oils mainly exists with five kinds of forms in water: (1) floating elaioleucite particle diameter that oils is greater than 50 microns, floats to water surface and forms oil film on can be comparatively fast after leaving standstill.(2) the elaioleucite diameter of dispersed oil is less, and generally at tens microns, suspended dispersed is in water, but instability can be grouped to bigger oil droplet and floats to the water surface.(3) particle diameter of oil in water emulsion owing to use interfacial agent or mechanical effect, makes oily emulsification and water form stable emulsion generally below 10 microns, has the stability of height, only depends on static being difficult to and water sepn.(4) oil content of dissolving oil is scattered in the water body with molecularity or chemical mode, forms stable homogeneous system.(5) oil that adheres to suspended solid surface in the water of solid attaching oil.
The boats and ships oily water comprises water ballast, washwater and the cabin limber water of boats and ships.The oil content concentration of water ballast can reach 3000mg/L-5000mg/L, and the oil-containing kind is simple, and oiliness mainly is floating oiling and dispersed oil, and the oil in water emulsion oil-containing is very little, handles than being easier to; The composition of washwater mainly is the phenol of oil, mud and iron rust and trace etc., and oleaginousness is generally 30000mg/L.The emulsification degree of oil content is than water ballast height in the washwater, because need use the vexed cabin of steam during washing of tanks, and then with 80 ℃ high-pressure water heating flushing, the also use washing composition that has, the profit thorough mixing, the emulsification degree is higher; The composition of cabin limber water is comparatively complicated, except that containing multiple oil contents such as lubricating oil, heavy oil, light oil and mechanical impurity, when cleaning parts, also can use clean-out system, it will produce the serious emulsification of oil, and the oleaginousness height of limber water, variation range is also big, and the stirring of machinery very easily makes limber water produce second emulsifying in transport process.
