Description

Hydraulic cyclone separator

Technical Field

The utility model relates to the technical field of ballast water treatment, in particular to a hydrocyclone separator.

Background

To ensure safe marine travel of fully or partially loaded ships, when the ships are unloaded at ports, seawater is typically injected into ballast tanks containing various silt, algae, fish, and shellfish for regulating the balance of water in and out of the ship, which may and often does introduce local marine species (e.g., bacteria and multicellular species) into the ballast water. When the vessel arrives at the next port, the ballast water must be pumped out. If the water contains living organisms, it may cause biological contamination of the marine environment at the port.

Many companies have developed ballast water management systems and adopted various methods for ballast water treatment, and it is common to use mesh filtration systems that block eggs, larvae and large microorganisms through a mesh, and the filtration systems have capacitive devices, and during operation, there may be instances of back flushing clogged particles onto the filter screen, pump-out clogged sediment and microorganisms, and the like, and the filter screen is more susceptible to clogging, reducing filtration capacity, requiring frequent shut-down for cleaning, which may result in discharge of untreated ballast water, and is less safe and economical.

Disclosure of Invention

In order to solve the problems that the existing ballast water treatment is easy to block and has poor safety and economy, the utility model provides a hydrocyclone which can not block and improves the safety and the economy.

The technical scheme is as follows: the utility model provides a hydrocyclone separator, its characterized in that, it includes the separator casing, the separator casing includes barrel and lower cone, the outlet has been seted up to cone bottom down, it is the delivery port to go up the barrel top, go up the barrel in install upper portion with the reducer pipe of delivery port intercommunication, the vortex director is installed to the lower part import department of reducer pipe, go up the barrel water inlet of having seted up on the barrel external face, barrel water inlet department install with go up the barrel external face tangent inlet tube that just is the heliciform and arranges.

The water inlet of the barrel is provided with two vertically staggered water inlets, and the water inlet pipe comprises an upper water inlet pipe and a lower water inlet pipe which correspond to each other;

the radius of the spiral curved surface of the upper water inlet pipe is smaller than that of the spiral curved surface of the lower water inlet pipe;

the longitudinal sections of the upper water inlet pipe and the lower water inlet pipe are rectangular;

the upper water inlet pipe and the lower water inlet pipe share one inlet flange at a ballast water inlet;

the lower part of the speed reducing pipe is a reducing pipe with a downward flaring, and the vortex guider is arranged at the flaring;

the vortex guider comprises a middle cylinder and guide vanes distributed around the middle cylinder.

After the utility model is adopted, the ballast water with microorganisms flows into the upper cylinder body from the water inlet pipe, rotates in the upper cylinder body and then enters the lower cylinder body, the ballast water can reversely rotate and rise under the dual actions of centrifugal force and the inclined surface of the lower cylinder body, enters the speed reducing pipe and is sent out from the water outlet at the top of the upper cylinder body under the action of the vortex guider, and the microorganisms can continue to be discharged downwards from the water outlet at the bottom of the lower cylinder body because the specific gravity of the microorganisms is greater than that of water, so that the separation of the microorganisms and the ballast water is realized, the whole process cannot be blocked, no electronic control exists, the structure is a pure mechanical structure, and the safety and the economy are greatly improved.

Detailed Description

See fig. 1 to 4, a hydrocyclone separator, it includes separator casing 1, separator casing 1 includes barrel 2 and lower cone 3, the outlet has been seted up to lower cone 3 bottom and is connected

drain pipe

4, 2 tops of last barrel are the delivery port and are connected outlet pipe 5, install reducer 6 in the barrel that communicates with the delivery port in last barrel 2, the lower part of reducer 6 is the reducing pipe of flaring downwards, the vortex director is installed to the lower part flaring department of reducer 6, the vortex director includes middle cylinder 7 and distributes in the guide vane 8 around middle cylinder 7, two staggered barrel water inlets about having seted up on the 2 outer peripheral faces of last barrel, barrel water inlet department installs and is tangent last inlet tube 9 and the lower inlet tube 10 that is the heliciform and arranges with last barrel 2 outer peripheral faces.

The longitudinal sections of the upper water inlet pipe 9 and the lower water inlet pipe 10 are rectangular, the upper water inlet pipe 9 and the lower water inlet pipe 10 share one inlet flange 11 at a ballast water inlet, after ballast water is sent in from the inlet flange 11, the ballast water enters the upper water inlet pipe 9 and the lower water inlet pipe 10 respectively in two paths, the fluid is divided into two paths through the double water inlets, the upstream flow passes through the upper spiral curved surface of the cavity of the upper water inlet pipe 9, and the downstream flow passes through the lower spiral curved surface of the cavity of the lower water inlet pipe 10. The radius of the spiral curve on the cavity of the upper water inlet pipe 9 is smaller than that of the spiral curve under the cavity of the lower water inlet pipe 10, and the smaller radius curve generates centrifugal force in advance, so that the flow speed in the cavity of the upper water inlet pipe 9 is increased, and the angular speed in the cavity of the upper water inlet pipe 9 is higher than that in the cavity of the lower water inlet pipe 10. According to the centrifugal force equation [ F = m r ω ] of the cyclone cylinder with larger radius²]Wherein m is mass, ω is rotational angular velocity, r is distance from the center of rotation, the centrifugal force of the fluid in the cavity of the lower water inlet pipe 10 is greater than the centrifugal force of the fluid in the cavity of the upper water inlet pipe 9, and the reducer pipe 6 makes the combined upper and lower water flow rotate more greatly, hindering the gravity of the water flow from flowing downwards. Most of the particles in the water are concentrated near the cylinder wall, and the treated water flows into the reducer pipe 6 and is discharged through the water outlet pipe 5. The vortex guider composed of the middle cylinder 7 and the guide vane 8 is arranged at the inlet at the bottom of the deceleration pipe 6, so that the generation of vortex bubbles is prevented, and the treated water can easily flow upwards. The guide vanes 8 are bent plates welded to the speed reducing pipe 6, so that the treated concentrated solution can effectively flow into the speed reducing pipe 6. The treated water flows upwards through the water outlet pipe 5, the lower cone 3 induces the impurities injected into the water tangentially to do circular motion, and the impurities in the water flow are induced to do rotary downward motion under the action of gravity, so that the impurities are separated and discharged. This drain water flows to the drain line 4 to be drained.
