Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a mobile water treatment device, and more particularly a
K relates to trailer-tower-mounted equipment that includes a coarse filter unit and a plurality of hydrocyclones and that can be moved from one location to another for purifying water contained in a cooling tower water tank.

Large quantities of water are used in industry for various cooling purposes. For this purpose, power plants, distilleries,
For the cooling of condensers in refineries or chemical plants, between internal combustion engines in diesel power plants, gas engines in compression or pumping stations, for the cooling of gasoline engines in automobile or aircraft plants, in refrigeration or liquid gas production plants. for the cooling of compressors, for the cooling of chemicals and other products, for air conditioning, and for various other cooling processes. The amount of water required for cooling varies considerably depending on the temperature of the cooling water and the particular application being applied. The cooling water source can be groundwater, surface water or seawater. While surface water typically undergoes large seasonal variations in temperature, well water's constant temperature makes it very convenient for one-time use for cooling purposes. It is clear that in places where sea water can be used, the amount of water obtained depends only on the size K of the water spouts, pipelines and pumps. However, seawater is generally used only once and then discharged for disposal.

Cooling systems can become clogged with scale, corrosion deposits, sludge, and organic growth. The primary scale that forms blockages in cooling caps is calcium carbonate, which is formed by the decomposition of calcium dibutentate into calcium carbonate, carbon dioxide, and water. The most common type of corrosion of steel containers is dissolved oxygen corrosion caused by the oxygen content of dissolved air. Cloudy water containing coarse sediments or fine suspended colloids is considered to be rejected in most cooling systems because these suspended particles form sediments that cause failures and blockages. Iron or manganese bacteria, known as "Crenothrix," are a nuisance in cooling water because the bacteria form thick clumps that slow down flow rates and block flow channels. It is.

Cooling water specifications vary widely with different water classes for different industrial applications, so that the water may contain heat-blocking scum, mineral or organic matter, and other blockages5. All that can be said is that such precipitates should not form and that under the particular conditions of use or reuse the water should not be broadly corrosive. Common categories based on use include single use and recirculation. As the name implies, in single-use cases, the cooling water is used only once and then discarded. Any treatment required is therefore inexpensive, and such methods are only practicable where large quantities of water are available. The most common devices circulate cooling water through a chiller and are cooled in a cooling tower or spray pond.
It is then recycled.

A cooling tower is an enclosed device for evaporative cooling of water by contact with air. This cooling is achieved by the exchange of latent heat resulting from the evaporation of some of the circulating water and some of the heat transfer. Such devices can be classified as ponds, atmospheric towers, chimney towers, and mechanical ventilation devices. Cooling ponds are the simplest and cheapest way to cool water. This method consists of a large pond in which cooling occurs due to K when the surface of the water comes into contact with air; the cooling water is pumped from one end of the pond, and the heated water is returned to the other end of the pond. . An atmospheric tower is a tower in which the movement of air through the tower depends solely on the state of the atmosphere. The wind blows horizontally and the water falls vertically due to gravity, so the air flow is perpendicular to the water flow. A chimney tower is a tower in which air is introduced by a large chimney action onto the backing. Mechanical towers, on the other hand,
A tower that uses fans to move air through the tower. Such a fan can be located at the air intake or air outlet. In any case, all types of devices mentioned above include some type of kodama, which is the part directly below the cooling part that collects and retains the cooling water produced.

Cooling of water is done by cold lime method, sodium calcium exchange, 2
Steps may be carried out with cold lime and sodium calcium exchange, desalination, acid treatment, and chlorination treatment.

Removal of suspended colloids takes place by filtration.

In the past, the practice was to purify cooling tower water by permanent equipment built adjacent to the chiller. ° For example, constructing a purification area adjacent to a cooling tower;
This area typically included large and expensive purification equipment such as sand filters, pressure filters, gravity filters, backflow filters, activated carbon filters, zeolite filters, and neutralization filters. Although such permanent installations have been successful in purifying water from cooling tower water, such structures are expensive and suffer from a lack of flexibility and flexibility due to the permanent type of equipment involved. . Furthermore, the initial capital investment involved in such equipment is significant, and it cannot be easily moved from one location to another to perform more than one piece of equipment.

The shortcomings of the prior art have been overcome by the zero source @flc, and a commercially acceptable embodiment of a clarifier for cooling tower water, etc. is provided herein, in which the cooling tower, water Not only can solids and sediment be completely removed from the food water, but it is also capable of performing other tasks that are completely beyond the capabilities of conventional contacting equipment. However,

The present invention relates to a movable clarification apparatus which is provided with auger means for removing sludge and sediment from said tank.

The present invention also provides a method for treating water containing solids, and more particularly, pumping water containing solids from a cooling tower water tank to a filter device containing an expanded metal lath filter material. capturing solids having a diameter of 9.53 m (0° 375 in) or more on the filter media, and directing the filtered effluent to a plurality of hydrocyclones in series, which cyclones consist of solids; forming an underflow and an overflow of effluent water; recycling the overflow effluent to the water tank; discharging the solids underflow to a sediment collection tank; and The present invention relates to a method for removing solid particulate matter from water in a cooling tower water tank comprising combining solids from an apparatus with solids in the tank from a hydrocyclone.

In one particularly ideal embodiment of the present invention, Exband Metal's 711 filtration material is used in a filter system to remove relatively large solids from cooling tower water in a water tank. The solids collected by the filter device and the solids discharged as underflow from the hydrocyclone train are mixed in a settling tank where the solids are removed by an auger. The auger may be permanently attached to a pivoting support system and can be lowered as required when in use, or the auger may be disassembled and attached to a pipe or hose hook carried by the trailer framework when not in use. can be stored in.

In another particularly buried embodiment of the invention, the filter device is placed above the sludge tank to facilitate the discharge of solids from the filter into the tank. The bottom of the filter device is provided with a dump valve that allows the compartment of the filter device to be purified of solids.

The chamber on the side communicating with the inlet of the filter medium occupies two-thirds of the total volume of the filter device, and the chamber on the side communicating with the outlet of the filter medium occupies the remaining of the total volume of the filter device. It accounts for one third.

In a further ideal embodiment of the present invention, an air-cooled diesel engine drives the dumper of the present invention, and the pump pumps between 1514 and 3785 rpm with a head of 72 feet. The one that has the ability to deliver j (40G to 1000 gallons) is selected. Preferably, the pump is a self-vacuum priming solids-capable centrifugal pump powered by, for example, a Lister HR-2 air-cooled diesel engine. In the embodiment of the invention described herein, the pump suction and discharge piping is 10°16cI.

A further feature and object of the invention is a solids removal device for water contaminated with precipitation from cooling tower water clouds, which also removes solids during operation of the cooling tower and returns the flowing water to water gold. The W! The objective is to provide a device that allows

Yet another feature and object of the present invention is to provide a method and apparatus for reducing the volume of contaminants in the water of a cooling tower water cloud, thereby reducing the volume of contaminated water dumped under BP personnel supervision. It is.

These and other features, objects and advantages of the invention will become apparent from the following detailed description, which refers to the various reference numerals in the accompanying drawings.

Although FIG. 1 shows an overall view of the apparatus of the present invention, it is only shown functionally to facilitate understanding of the invention. More particularly, a cooling tower water tank 10 is shown in which, without the present invention, the cooling water would collect together with the solid particulate material that would otherwise be carried by the cooling water. It will be done. This water metal 10 also contains relatively fine sediments such as dirt, dust, mud and sand, as well as tools such as bolts, nuts, pebbles, stones, wrenches, and fallen animals such as dead pigeons. It is known that when relatively large objects such as the above are included, the value becomes K. Since the efficiency of the cooling tower will be reduced if the solids accumulate to a substantially noticeable extent, a pump 11 is provided to blow out the deposits in the water erosion 10.
These deposits, such as water and solids, are pumped to a treatment device where the uninvited solids are removed and the purified water is recycled to the water metal 10.

Pump 11 is a self-vacuum priming solids-capable centrifugal pump that is closely connected to either a Lister HR-2 or 8T-2 air-cooled diesel engine.

With a 10.16c11 (4 inch) suction and discharge piping system, the pump can handle solids up to a diameter of 6°3Scl& (2.5 inches). Pump 11 has a flow rate of 15141 (400 gallons) per minute and a water head of 22.86 m (75
It is preferable to operate with feet). If desired, the pump could be as described above but powered by a Lister HR-3 air-cooled diesel engine and
Larger pumps can also be used, such as those with 2 inch inlet and outlet pipes. In this case, the pump handles solids up to 7.62 cm (3,0 inches) in diameter and pumps 37,851 (1000 gallons) per minute, water 1122.8
Operates at 6 m (75 ft). Although the particulars described above are preferred embodiments of the invention, it is obvious that pump systems having specifications different from those described above will occur to those skilled in the art and could be adopted anywhere as equivalents. Probably.

In any case, the pump 11 sends the sediment from the Kodama 10 to the filter device 12, which is connected to the feed inlet 14 from the 4 pump 11 as shown in Figure 3A. It includes a large tank 13 with a purification fluid outlet 15 for conveying the solids-laden fluid to a further purification unit. A discharge valve 16 is provided at the bottom of the filter tank 13 to remove solids from the tank 1.
It should be removed from the inside of 3. A filter material 17 extends across the filter 13 between the inlet 14 and the outlet 15 and serves to trap large solids in the tank closer to the inlet 14. The preferred filter material 17 is 1.
27 tan (0.50 inch) extended metal, this filter material actually has a diameter of 0.953 (1
Solids larger than 1 N (0,375 inch) are removed, while particles with a diameter of 41 g (0,375 inch) or less are passed through filter media 17 to outlet 15. Although we specifically mention expanded metal, it should be noted that other equivalent filtration media such as standard wire mesh screens may also be employed.

Durable expanded metal has been found to be very satisfactory because it is stronger than a uniform wire mesh screen and is better able to withstand forces exerted by objects impinging on the filter media. □ Exband metal filtration screen material 1741 is placed in the tank 13, and the inlet chamber 1B and outlet chamber 19 are connected to the chamber 18.
is formed so that the size k is twice that of the chamber 19. In other words, chamber 18 occupies a volume twice as large as chamber 1902,
Therefore, a considerable amount of tBiI type objects accumulate in the chamber 18 due to the action of the sieve of the filter 17, and the larger chamber 1
8 provides space for such solid objects as they are deposited. Valve 16 is positioned in communication with both chambers 18 and 19, so that filter 12 can be flushed out by opening valve 16 and flushing solids from each chamber 18 and 19. Can be purified.

The valve member 16 is preferably a 12 inch gate valve.

The effluent from the filter 12, which contains relatively small contaminant particles, passes through the supply line 15 to the liquid filters arranged in parallel in a row 20, as shown in FIG. Small diameter solids are sent to 21
The purified effluent is removed by a line of hydrocyclones in A-21C and sent to Kodama l through the supply line 22.
recycled to O.

The basic unit of a centrifuge is a conical assembly in which solids are separated from a fluid or suspension in a slurry by centrifugal force, without the need for any moving parts. It occurs as a result of the rotation of fluids within the body. Fluid is directed into the cone through a tangential inlet, and this fluid imparts a rotational motion [generating centrifugal force]. This force separates the fluid into conical layers, the heaviest of which moves along the conical wall and falls by gravity to the underarm outlet. The purified fluid free of solids floats inward towards the vortex at the center of the cone and exits through the overflow outlet.

Although the inlet and overflow channels are of fixed size for a given cone, the underflow control can be controlled to modify the separation effect.

The high centrifugal force of a hydrocyclone is generated by a tangentially penetrating feed flow k with a constant head pressure, such as from a centrifugal feed pump. In a hydrocyclone with a balanced design, the purified fluid travels in a spiral toward the apex in the direction of transport, and the spiral flow between the two forms an overflow and eliminates fluid loss in the underflow. It can be adjusted as follows.

If solids are present, they will settle on the outside wall in a downward spiral flow, and when the fluid changes direction, it will underflow and drain due to inertia. .

The removed solids have no liquid on their surfaces. If the opening in the underflow is large enough to handle all feed solids separating into the underflow, the balanced cyclone will operate as a "spray discharge".

If the feed solids separating into the underflow cannot pass through the underflow opening, the solids discharge will be a four-pipe or sausage discharge;
When the overload is indicated, it becomes .

In any case, the row 20 of liquid cyclones is depicted in more detail in FIG. 2, and the detailed structure of one of the rows of hydrocyclones is illustrated in FIG. . However, FIG. 2 shows a plurality of individual hydrocyclones 23 including a feed header 25, a effluent outlet header 26, and a solids discharge ramp 27 connected to the skid 2.
4 is shown mounted on top. Since the feed inlet 28 of each hydrocyclone is connected to the feed header 25,
All fluid swirler units 23 operate in parallel.

The overflow outlet 29 of each hydrocyclone is connected to the outlet header 26 for returning the purified liquid to the water sound 10 via the circulation line 22 for recirculation. Each fluid swirler includes an underflow discharge 30 for solids, each of these discharge openings 30 being directed into the trough 27 and 1. - Collecting all discharged solids with a diameter smaller than 0.953α (0.375 inches) and discharging these solids out of pipe 31 and dumping them into tank 32 along with the solids from filter unit 12 .

Each hydrocyclone 23 is shown in more detail in FIG. 4 and can be seen to have an inlet 28 oriented tangentially with respect to the supply chamber 33. The supply chamber 33 includes a cylindrical vortex finder (not shown) that communicates with an overflow outlet 29 for discharging cleaning fluid from the cone 34 . The upper part of the hydrocyclone 23 comprises an inlet 28, an outlet vessel and a chamber 33 made of polyurethane, in this case a conical part 34 and an outlet part 30.
It is preferable that it be made of aluminum. The cone 34 may, if desired, be provided with a queiner of Frethane, polyurethane, high carbon rubber, Buna-N, or nitride rubber for abrasion resistance. The top section 33 is secured to the cone section 34 by a quick release stainless steel snap fitting 35 which allows the new piping system to be attached to the cone section 34 by simply releasing the snap fitting 35 manually. can be located in A typical assembly as shown in FIG.

through the sludge tank 32, and this tank 32
includes an auger 36 having a feed end 37 and a discharge end 38 therein for transporting solids from tank 32 to a dump tank (not shown) for disposal. Five-degree drains 39 and 40, as seen in use, are provided at the bottom of tank 32 for flushing and cleaning when necessary. In those instances where the liquid slurry is collected in tank 32, pump 41 can be used to pump the dough from tank n. Auger 3
6 is a standard grain auger with a diameter of 15.240 II (6 inches), preferably powered by a diesel engine.

Referring now to FIG. 5, the embodiment of the invention described herein has all of the equipment schematically illustrated in FIGS. 1-4 mounted together as a movable unit. Yes, it can be towed from place to place. More specifically, the trailer illustrated in FIG. 5 has a frame 50 supported by wheels 51 and a carrying tank 32 at the rear end of the vehicle. The gooseneck connecting portion 52 is
For example, it is provided at the front end of the vehicle at the frame connection for attachment to a truck. A plurality of outriggers 53 are attached to the frame 5o to prevent the trailer from being raised with jacks and jacks during use so as not to apply any load to the wheels 51. A pipe hook 8 extends across the top of the trailer to accommodate hoses and pipes needed while the equipment is in use. A ladder 55 allows access to the hook 54 for storing or removing sections of pipe or hose from this hook.

Referring again to FIG. 5, the filter 12 can be seen positioned toward the forward end of the trailer and sandwiched between the tool box 56 and the diesel engine 57 that drives the pump 11. A pivotable and tiltable column 58 extends upwardly from the tank 32 and includes a bracket 59 to which the auger 36 is mounted. The auger 36 is shown in the stowed position in FIG. It should be noted that the tank 32 is positioned within the tank 32. In FIG. 5, an electric motor 6° for driving the auger 36 is shown as well as a guard 61 for protecting the feed end of the auger 36.

A row of fluid swirl separators 20 shown in FIG.
is illustrated in more detail in FIG. 6, where the supply line 15 connected to the header 25 can be seen. The discharge header 26 returns the effluent to the cooling tower water tank 10 and the solids truck 727 collects the underflow discharge from each fluid swirl separator 23 so that the pipe 31 directs these collected solids to the tank 32. Set up. trough 2
7 becomes clogged at the discharge port 31, the overflow line 62 is attached to the trough 27 and the trough 2
Transfer the clogged substance inside 7 to tank 32. In Figure 6,
Four swirlers 23 are shown on one side of the header;
It should also be noted that four hydrocyclones are placed on opposite sides of the header 25, with a total of eight separators 23 all connected in parallel. Eight hydrocyclones are preferred, but any desired number of parallel units, for example from 4 to 24, can be employed.

Referring now to FIGS. 7 and 8, another embodiment of the invention appears virtually identical to the embodiment previously described with reference to FIG. However, in the variant of FIGS. 7 and 8, the filter device 12 is positioned to discharge the solids via the valve 16 directly into the tank 32;
Legs 63 on the filter 12 therefore raise the filter above the tank 32 and the valve 16 is connected to the manual wheel 6.
Whenever it opens, the valve 16 discharges into the tank 32, resulting in K. In FIG. 8, the auger 36 can be seen in operation on the post 67, with the feed end covered by the guard 61 and close to the wall 65 of the tank 32. Otherwise, the operation of the devices of FIGS. 5, 7, and 8 is the same.

In operation, the flexible hose 66 from the pump 11 is stretched to a volume of water 10 after the trailer 5 (1) is towed alongside.
To release the weight of the engine, it is jacked up and placed on the outrigger 53. With the hose 66 in place, the engine is started to drive the pump 11 and the contents are drawn into the filter 12 from the water volume lO.

Solids larger than 0.375 inches in diameter are captured by screen IHC and periodically flushed by valve 16 to sludge tank 32 for disposal by auger 36. The outflow water from the filter 12 is directed to the header 2 of the swirler in line by line 15eC.
5, where a finer separation is performed and the liquid, which is virtually free of solids, is sent to the discharge header 2.
6 to the water volume 10 by line n. Uninvited solids are discharged by each underflow discharge of each separator 23 into a trough 27 and fed to a pipe 31 for discharge into a tank 32. tank 32
The sludge is periodically removed using eF36 and - at the end of the cycle, cleaned using drains 39 and 40 and pump 41. After the amount of water 10 has been purified to a satisfactory degree, the engine 57
is stopped and the hose 66 is removed from the water quantity 10 and stored in the hook 54. The railer 50 is then lowered back onto the wheels 51 and prepared to be towed to the next volume of water lO for further purification operations, generally as described above.

A number of advantages are obtained by the inventive device described above.

For example, in a typical five-cell cooling tower, the water volume is 45.7 m (150 ft) long and 18° wide.
It ranges from 9 m (60 ft) to a depth of 0.91 to 3.68 m (3 to 12 ft). Chemically treating this much water requires a considerable amount of money, but
In the mobile device of the present invention, the water is purified and recirculated to the water volume, so that it is made fresh again with the added cost of discharging the used water and chemical treatment of the water. This saves the cost of adding fresh water. Thus, in the apparatus of the present invention, the used droplet cooling tower water can be purified and recycled as fresh but still containing treatment chemicals as a basin liquid. The apparatus disclosed herein also provides that a quantity of water can be purified within the apparatus even when the cooling tower is operating, and the cooling tower may also operate utilizing water from the cooling tower. Since there is no need to take a break from the plant equipment currently in use, the time savings associated with the plant equipment is significant. In this way, the water in one water basin passes through the device of the present invention, while the plant equipment and cooling tower can continue to operate and operate. Also, used cooling tower water, which was previously forcibly transported and dumped at EPA-approved sites, can be recycled within the device of the present invention and can be recycled under dump site regulations. Water volumes can be recycled back into the water for reuse without paying the required costs on a per-unit basis.

Although the description so far has been made regarding the purification of the cooling tower water supply equipment, it is understood that ``this device has a decisive effect in separating and purifying solid matter sludge.'' For example, it is very useful in the chemical industry to remove solids from precipitated water, just as coal waste is removed from water in tanks and ponds. It is also useful in steel plants to remove scrap steel from water in lifting stations, settling tanks, and cooling towers. Solid sulfur was separated using the apparatus of the present invention.

As will be apparent from the foregoing description, many other changes and modifications may be made to the structures and methods described herein without departing substantially from the essential concepts of the invention. Accordingly, the forms of the invention described herein and illustrated in the accompanying drawings are given by way of example only, and
It should be clearly understood that no limitations on the scope of the invention are intended.
