Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The technology intended to recycle hazardous waste is relatively new. The laws generally enforced by the Environmental Protection Agency were originally established to control the disposal of hazardous waste by storage, transportation and landfill. However, in situations where toxic substances are generated by companies, companies are required to minimize the generation of such hazardous waste and immediately reduce landfill disposal.

In light of the above circumstances, recyclers have developed mobile systems to assist hazardous waste generators at the location of hazardous waste generation. Hazardous waste handling rules are
It allows mobile systems where fixed systems cannot be used and allows hazardous waste generators and recyclers to operate in a manner that is in their favor according to the law.

In all known mobile waste recirculation systems, the hazardous waste is encapsulated rather than entrained in a matrix of material that cannot be destroyed by normal physical or chemical means. It has become. When using encapsulation, damage to the integrity of the capsule,
That is, there is always a risk of cracking and destruction accompanied by the emission of hazardous waste.

[0024]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Before describing in detail the individual embodiments of the invention shown in the accompanying drawings, it is appropriate to review the invention and prepare for the following detailed description. It appears to be.

Many recirculation systems have been developed to treat hazardous wastes, and the patents discussed above are typical of such systems. The majority of recycle systems deal with organic toxic substances, including the use of waste in energy systems and the distillation of solvents. A system designed to recover copper, gold and other metals could be described as processing certain inorganic components. The inorganic recirculation system
It can be applied to all inorganic substances, not specific metals,
And the chemistry of binding depends on whether the components are separated or mixed.

In a typical application, a particular mineral recovery system is set up only for the particular component that it is desired to remove, and such a system would be used if the mixture or exact component indicators were not met. Generally fails.

Organic material treatment systems are generally adapted for evaporation or incineration of components, but inorganic elements are not incinerated. They melt but are not destroyed anymore,
And in most cases, the evaporation temperature of the inorganic material is too high to utilize evaporation. Therefore, systems designed to treat organic waste cannot be used to treat inorganic waste.

In the operation of the present invention, it is not necessary to care about the chemical immobilization of organic substances which may be present in the mixture. Since the present invention involves the use of kilns or furnaces to burn waste materials at high temperatures, any organic material that may be present will necessarily be burned out during the kiln treatment process.

The present invention is practiced by chemically reacting an inorganic component material in a mixture by a series of oxidation-reduction reactions, the reaction bringing the components into a chemical state that permits subsequent binding. Let Various inorganic acids and alkalis were used to drive these reactions, which are discussed in more detail below. After mixing such substances with the hazardous waste, the mixture is then further compounded with silicates such as sand or clay which are added based on the desired end product. After all the component parts have been thoroughly mixed together, heat is applied to the mixture to cause a chemical reaction that binds the inorganic component material into the silicate matrix, which is inert and has common physical properties. Or it cannot be separated by chemical means. After chemically fixing the treated material, the resulting product is packaged and shipped to the end user.

Whenever hazardous waste is handled or otherwise treated, government guidelines regarding under what circumstances the material is handled and disposed of will always come into play. Government guidelines differ between recycling and recycling. According to governmental guidelines, reprocessing involves the recycling of waste or the recovery of substances from waste. Under the definition of material recovery, the recovered material itself is considered to be recycled, but the residue remaining after recycling the recovered portion is still considered to be hazardous waste. For example, if a drum of mixed waste solvent was processed to remove one of such solvents for reuse, the recovered solvent would be considered recycled, and the balance of the mixed solvent would still be hazardous waste. It is believed that there is.

On the other hand, government guidelines define recycling as a beneficial reuse of the whole substance. The present invention is specifically contemplated and designed to completely recycle the material treated thereby. No inorganic components found in hazardous waste are separated during the process carried out in accordance with the teachings of the present invention. In practicing the method contemplated herein, where all of the constituent materials are contained in the final recycled product, the product being used effectively in one way or another, Complete a complete chemical analysis of the material to be treated before starting the recycling process. Since the method of the present invention is primarily used only in applications with a mixture of minerals, tests are also performed to confirm that the mixture is primarily mineral. As a result of studies by the applicant, the method of the present invention can be safely carried out as long as the inorganic component of the mixture is 20% or less of the total mixture. However, no radioactive components should be included in the mixture intended to carry out the invention.

Referring to FIGS. 1 and 2, a first embodiment of the apparatus of the present invention is designated by reference numeral 1, which is a mixing truck 10 and a recirculation trailer 40.
You can see that it contains. The mixing truck comprises a feed chute 11 located at the rear of the truck 10, which is designed to receive the substance from the user's substance storage container 13 and to carry the substance consisting of harmful inorganic waste to the feed hopper 15. The hopper directs material to the auger 17, which operates to grind the solid portion, and the auger of the conveyor belt 19 which carries the material to the inlet manifold 21 of the reactor tank 23. It has an outlet located above.

The reactor tank contains a mixing device 25, which is a paddle 2 rotated by a motor 29.
Includes 7. As best shown in Figure 2,
At the bottom of the reactor tank 23 is provided a pump 31, which delivers fluid from the tank 23 through a conduit 33 to a valve 35, which valve comprises two remote control valves 37, 3, 3.
Includes 9.

As shown in FIG. 2, the passage 33 is connected to a first branch passage 22 and a second branch passage 24, which allows the fluid to be recirculated back into the tank 23. And the branch 24 directs the fluid at the rear of the vehicle to the container filling table 3.
6 has an outlet branch for feeding to it, and on top of which is placed a container 38, which is arranged such that the outlet 26 of the conduit 24 is removable therein. Conduit 2
Once the mixture from 4 is filled in the container 38, it is sent to the recycle trailer by any desired means (not shown).

In the preferred embodiment of the invention, valves 37 and 3 are provided.
9 is solenoid actuated and can include a single valve head that can only open one of the branches at a given time. Thus, considering the present invention, when valve 39 is open and fluid can be recirculated back through conduit 22 to reactor tank 23, valve 37 is closed to prevent fluid flow out of outlet 26. Will. Reactor tank 23 to add a new batch
When it is desired to empty the container, valve 39 can be closed and valve 37 opened to allow fluid to be pumped by pump 31 through conduit 24 to outlet 36 and into container 38.

Conveyor material 19 and manifold 21
While adding to the reactor tank 23 via
The treatment chemicals from the reactor 8 are fed via the conduit 32 to the reactor tank 2
Add in 3. Of course, when adding solid chemicals to the tank 23, add them to the chute 11, hopper 15,
It can be loaded via an auger 17, a conveyor belt 19 and an inlet manifold 21.

As mentioned above, the substances to which the chemicals have been added and mixed well in the reactor tank 23 are delivered via the conduit 24 from the outlet 26, and these substances are placed for this purpose on a container filling table. The filled container 38 is filled. Thereafter, each container 38 is delivered by any desired means from the container fill table 36 to a position adjacent a ceramic-lined door 41 located on the sidewall 42 of the recirculation trailer 40.

If desired, the mixing chute, the supply hopper 15, the auger 17, the conveyor belt 19, the inlet manifold 21 and the reactor tank 23 can be combined into a single structure to simplify the mixing truck. You can also

When referring in this regard, reference is made to FIGS. 5, 6 and 7, which disclose another embodiment designed as an alternative to the mixing truck 10.

As shown in FIGS. 5 and 6, it can be seen that the mixing trailer 200 is a semi-trailer type. Of course, the mixing trailer 200 can be incorporated into the vehicle in the same manner as mixing truck 10 if desired. Referring specifically to FIG. 6, the trailer 2
00 includes a mixer 201, which is a filling door 2
03, cover 205, gate valve 210 through outlet 20
Valve 210, which includes an outlet 207 connected to
Has an actuation rod 211, which is selectively reciprocated by the use of a hydraulic piston-cylinder 213.
Of course, the hydraulic actuator 213 could be replaced with other actuating means, such as solenoid actuators, gas actuators, and the like.

The outlet 209 is located just above the tray fill platform 215, where it can be seen that the tray 38 is supported on a tray support 239, which supports all overflow from the tray 30. It is surrounded by a reflux pan 217 provided to capture the flow.

Referring further to FIG. 6, mixer 2
Extending into 01 is an extension drive shaft 219, which is rotated by a drive motor 221. Fixedly mounted on the drive shaft 219 is the mixer blade 225 shown in FIG. 7, which includes an inner ribbon helix 227 and an outer ribbon helix 229. As should be understood from FIG. 7, looking down the drive shaft 219 from its end 220, it can be seen that the inner helix 227 rotates clockwise about the shaft 219, while the outer helix 229 shows the drive shaft 21.
It turns out that it rotates around 9 in the counterclockwise direction. Therefore, the material near the drive shaft 219 is
The material adjacent to the outer helix 229 is thereby moved in the second direction while being moved by and thereby moved in the first direction.

Mixing vanes 225 are sized and constructed to rotate in close proximity with respect to bottom surface 202 of mixer 201. In the preferred embodiment, the bottom surface 202 is made semi-cylindrical so that the outer helix 229 is closely spaced with respect thereto through the periphery of the surface 202. Thus, the interaction between the outer surface of helix 229 and the inner surface of surface 202 will facilitate the grinding of the material within mixer 201.

Further referring to FIG. 6, an air compressor 230 is installed on the mixer driver 221.
It is equipped to supply air to the various valves in the system, and for general use the following air compressor 1
83 is provided in the manner provided.

Still referring to FIG. 6, since the dust generated during the process of the present invention is harmful to the operator and must be collected for safety reasons,
A dust collector 240 is provided in the trailer 200,
And it is provided for collecting dust generated by the mixing action of the mixer 201 or from other sources. Further, the mixer 201 is provided with a tank 250,
It can be used to store water, chemicals or other substances that can be selectively supplied. Additionally, doors 241 and 243 are provided at the front end of trailer 200 to provide access to large storage areas. Another storage area is provided on the front of the mixer 201 at reference numeral 245, and exhaust fans 237, 239 are also provided adjacent thereto.

Furthermore, in the storage area communicated by the doors 241, 243, an electric panel 251 and a locker 253 are provided.
Also, tools and parts containers 255 may be provided.

It can be seen that in the operation of the mixer 201, the filling chute and the conveyor are omitted by the top passage 203 through which the harmful substances to be treated can be dropped. The mixer vanes 225 spiral 229 in the immediate vicinity of the surface 202 of the mixer 201 replaces the auger function and allows for the grinding of the material placed therein. The tank 250 is similar to the tank 28 of the mixer truck 10, and the structure of the mixing vane 25 with the inner helix 227 and the outer helix 229 replaces the function of the recirculation conduits 33, 22 and the valve 37. , 39 are unnecessary. In addition, conduit 24 and outlet 26 are replaced by a bottom outlet 207, valve 210 and outlet 209. Finally, the filling table 36 is replaced by the filling table 215.

The means used to move the tray 38 from the container fill 36 of the mixing truck 10 or the fill 215 of the trailer 200 to a position adjacent the door 41 on the recirculation trailer 40 may be, for example, a conveyor. It may be any desired means such as a belt system, lift truck or other vehicle or elevated crane system. Of course, any number of means can be used in this regard.

With particular reference to FIGS. 1 and 3, it can be seen that the immobilization trailer includes a kiln 43 having walls 45, 47 and 49 therein, which walls are preferably internally generated. Made of ceramic fiber lined material to help resist high temperatures. As the burner 51 extends from the walls 45 and 49, a gas, preferably propane gas, can be ignited and burned in the chamber 53 in the kiln 43. Propane is supplied from a propane tank to the burner 51, which is a trailer 4
0 may be included separately with a suitable removable fluid connection tube connected therebetween.

As can be seen with reference to FIG. 1, a door 41 lined with ceramic fibers is associated with walls 45, 47 and 49, and with reference to FIG.
It combines with a ceiling 42 and a floor 44 to define a sealable chamber in which the tray 38 is located (not shown but schematically based on the space shown for the tray 38 in FIG. 3). It is removably placed on top.

The purpose of the kiln or furnace 43 is to provide the energy necessary to drive the final chemical reaction. The examples discussed below are processed in a box kiln in which is placed a container 38 filled with the reacted compounded material. The box kiln used is designed to use a gas combustion burner,
It can be operated with propane or natural gas. In this particular kiln, the temporal sequence disclosed in the examples was used. However, any kiln or furnace design can be used as long as maximum temperature conditions are met. Some kind of furnace [600 ° F
A device capable of obtaining a temperature of -700 ° C] would not be usable in this operation. A furnace, such as an arc furnace, can be effectively used in this recirculation process. When using such equipment, the process specifications will generally be the same, but the time sequence of the kilns will change.

In operating the furnace, the reacted compounded material is placed in a crucible container. A furnace process time of about 3-4 hours is required to melt the material. At that point, the vitrified material can be removed from the vessel, or the treated material can be flowed through the furnace at a certain rate to allow the treated material to flow out for a continuous kiln process operation. it can.

Chamber 53 as shown in FIGS. 1 and 3.
Using the tray 38 therein, the burner 51 is ignited to raise the temperature in the chamber 53 to the desired level, such as 2,100 degrees Fahrenheit. During such heating of the material in the tray 38, a gas is generated which may contain liquid, gas or particulate harmful substances. Room 5
3 includes an outlet 55 connecting the scrubber 100 to the chamber 53, which removes all harmful particulate liquid and gaseous byproducts from the gas entering the scrubber 100 via the inlet 57. Specially designed to. The scrubber 100 has an entrance 1
01 and outlet 103, which is outlet 103
In the down-flow direction to the intermediate conduit 105, the outlet of which is connected at its outlet end to an exhaust fan 107, which draws gas from the scrubber 100 and makes it processable. Specially designed to assist.

As shown in FIG. 3, the inlet conduit 5
7 is there connected to a scrubber inlet manifold 58, and with particular reference to FIG. 4, the inlet manifold 58 is designed to cause a liquid to be sprayed onto the gas as it enters the scrubber 100. 1 It can be seen that more than one nozzle 109 is installed. Gas is forcibly added from the inlet manifold 58 to the wall 113.
Bend at a right angle due to the collision above, and then walkway 111
Forced to descend vertically through the passageway, which is connected to a convergent throat section 115, which section is connected to a venturi throat 117, the cross section of which is preferably rectangular. Yes and it has nozzle 1
Another low pressure water spray is fed through 19. In effect, the Venturi structure accelerates the gas to 4-6 times the velocity available at the inlet manifold 58. After passing through the throat 117, the gas transitions through a passage 121 of divergent cross section, which passage can slow the gas. It should be understood that the upflow gas of the throat 117 is dry, while the downflow gas of the throat 117 is wet due to the liquid being sprayed there through the nozzle 119, and this structure and The function sets the complete separation of the spray-drying area through the Venturi structure. Since a high temperature is applied, the cooling spray is then applied to the scrubber inlet 1 via the spray nozzle 107.
Supply at 37. A portion of the cooling water is then sent to the Venturi area. The reaction of gas and liquid in the venturi throat 117 uses a substantial portion of the energy that extends into the throat of the venturi 117 while allowing particles and other fines to set while allowing the gas to reach near 100% saturation. Designed to be retained within a small droplet of cleaning liquid by the shearing effect of liquid / gas interactions, which promotes the breakdown of liquid into fine liquid particles to initiate and / or complete chemical reactions Given a large surface for.

Immediately after leaving the branched passage 121, the saturated gas enters the receiver 123, at least a part of which is filled with the same liquid as sprayed through the nozzles 109 and 119. The receiver 123 includes a target box 128, which is fluidly connected to the rest of the receiver 123 via a port 122. The target box 128 is located in the center of the receiver 123, which is where most of the gas flow strikes. This liquid is designated by the reference numeral 125 in the drawing. As can be seen from FIG. 4, a closed recirculation system is included in the scrubber 100, which is the receiver 123, conduit 127, pump 12.
9, conduit 131, passage 133 with nozzle outlet 119,
It includes a passage 135 with a nozzle outlet 137 and a passage 139 with a nozzle outlet 109. It should also be understood that the structure of the scrubber 100 allows the liquid used in the system to drain downwards and into the receiver 123.
Liquid is drained into the conduit 127 by the drain outlet 124 in the receiver and recirculated through the system.

Gas impingement on the surface of the liquid 125 in the receiver 123 causes another energy consumption, whereby the cleaning liquid is discharged into the gas stream. During this operation, liquid bound particles are released into the main liquid storage area 123 and then removed using a filter (not shown) if desired. The rapid stirring, dispersion and collision of gases and liquids provides the opportunity for further chemical reactions to occur.

After gas impingement on the liquid surface in receiver 123, the gas turns 180 ° and rises through scrubber 100.

Before further discussing the flow path of gas from receiver 123, considering from the perspective of gas addition in manifold 58 due to energetic action / reaction of receiver 123, both solid and liquid should be cooled and saturated. And it is important to note that the scrubber system is primarily designed to transfer particles from the gas phase to the liquid phase. Due to the unique design of the scrubber of the present invention, this liquid disruption and mixing is so sufficient that chemicals can be added to the recirculating wash liquor and the reaction caused will liquify impurities from the gas phase. It can be chemically transferred into the phase. This scrubber design allows additives to be injected directly into the liquid recirculation system.

In further describing this, reference is made to FIGS. 1 and 3, which figures show a recirculation trailer 4
1 shows a drug delivery system 62 designed to deliver drug to receiver 123 on demand. For example, in a scrubber as included in the present invention,
It is important to treat the gas in such a way that it is chemically balanced prior to exiting the scrubber 100. The receiver 123 may have a pH sensing system therewith, which senses the pH of the liquid 125 in the receiver 123 and responds to changes in the pH of the liquid 125 by chemicals from the chemical reagent supply system 62. Is added to the liquid 125 to maintain a predetermined pH level, where a selected predetermined p
That level deactivates the drug delivery system 62 until H changes.

Again, as described above, after gas impingement on the liquid surface in receiver 123, the gas bends 180 degrees and begins to rise through scrubber 100. Bent 180 degrees, as best shown in FIG. 4, the gas passes through a scrubber zone which includes an orifice plate 141 having a plurality of V-shaped orifices that converge in the flow direction. The orifice plate 141 is specifically designed to evenly distribute the gas over the entire cross section of the scrubber body, and has the other purpose of being a support for the filler 143 below it in the preferred embodiment. It is sized to provide approximately 40% open area. The packing material 143 was contained in the liquid / gas phase separator section and the gas reduced the velocity entering the orifice plate 141 by 50-60% in the transfer section by reducing it to the above 40% value. I will go into it later. The orifice plate is useful for separating virtually all droplets of fluid that have embedded particulate matter contained in the gas stream. As the gas enters the filler 143, liquid is sprayed from the nozzle 137 and flows downward into the filler 143 to collide with the gas. This liquid flowing down through the fill material and the liquid carried in the gas from the target box 128 of the receiver 123 are combined to create a wash liquid layer on the orifice plate 141 at a depth of about 2 inches-3 inches. It is formed. With such a depth of liquid present in the filler 143, the gas bubbles through this area and then evenly enters the filler 143 above the liquid level. Filler 143 comprises expanded surface scrubber filler, each having a surface area of about 50-80 square feet per cubic foot. The nozzle 137 uniformly disperses the liquid at a rate sufficient to keep the liquid flow in the filler at about 80% of the full water volume. In the filler section, the gas undergoes a slow vortex flow in a countercurrent flow downward by gravity through the filler and orifices in the orifice plate 141,
And then it goes into the receiver 123, where the liquid is recycled as described above.

The filler 143 defines a region in the scrubber 100 referred to as the "chemical reaction center" of the scrubber, where sufficient time allows effective gas transfer into the wash liquor. ing. As shown in FIG. 4, on the filler 143 and on the nozzle 137, a release air section 145 is provided to facilitate the final separation of the liquid droplets.

If the gas entering the filler 143 is still very hot, the liquid sprayed filler 143 also acts as a cooler, reusing the liquid that would normally be lost in the water vapor column. The release area 145 has been noted above as the area where the final separation of liquid droplets occurs. Above and below this area is a dropper 147 which, in the preferred embodiment, is composed of a fine fiber mesh surrounded by a rigid frame containing passageways 111. Dropper 147 removes all residual liquid from the gas stream. Due to the presence of the dropper, a small amount of liquid from the filling material 143 can reach the bottom of the pad, which has the ultimate high efficiency wet filter function and is a gas for uniform gas flow. It gives resistance. After the gas exits the fine fiber mesh dropper 147, the gas passes through an orifice plate 149 provided to ensure a uniform flow from the dropper 147 towards the scrubber outlet. At the downflow of the orifice plate 149 is provided an outlet 103 of sufficient size to handle the system design flow index in cubic feet per minute. Outlet 103 is the only outlet from scrubber 100, and all gas must pass through it and then through exhaust fan 107 to the outlet. The receiver 123 is provided with a clean box 155 to enable cleaning of the receiver 123 as desired. Drain 157 allows for periodic drainage of the receiver or the liquid stream contained therein to separate a filtration system (not shown), where the liquid can be purified. Of course, the filter 159 through the passage 12
7 can be provided and the filter 159 is placed where it can be easily and regularly cleaned.

Having described various aspects of the scrubber in great detail, certain operating points will now be disclosed.

It should be understood that some fluid will be lost in the form of water vapor contained in the gas exiting the outlet 103 due to the high temperatures that the cleaning liquid is necessarily subjected to. . These losses must be replenished to allow optimal operation of the scrubber 100. There, a level sensor can be included in the receptacle adjacent to the clarification box 155 and a pump can be placed in between to interface with an additional source of cleaning fluid. In this method, when the level of fluids 125 and 126 in receiver 123 falls below a predetermined level as sensed by a level sensor (not shown), the fluid in receiver 123 is responsive to the sensing. The pump (not shown) is activated to deliver additional wash solution from the receiver (not shown) until the levels of 125 and 126 rise to a predetermined level when sensed by the above level sensor. To be
At this point, the pump will be deactivated until the liquid level in receiver 123 is again reduced to a predetermined low level.

If desired, the above pump may be replaced with a purification box 155.
The purification box 155 can be provided with an observation port 161 through which the receiver 123 can be observed without opening the purification box 155.

In the operation of the scrubber 100 of the present invention, gas falls into the inlet 109 and is immediately cooled at the nozzle 139. Gas is collision conduit 11
High energy Venturi throat 1 through 1,113
Move directly into 15, 117, 121. At the venturi, another liquid is sprayed onto the gas through the nozzle 119 and the gas is discharged from the venturi section onto the surface of the water in the target box 128 of the receiver 123, where further mixing and cleaning occurs.

The mixture is then forced into orifice plate 141 after bending 180 degrees for liquid-gas separation. As the gas is pulled through the absorption zone containing the filler 143, the water flowing down from the nozzle 137 associated with the filler structure creates a slow vortex path through which the gas passes. Is finally purified.

The gas then passes through the final dropper 147, through another orifice plate 149 designed to homogenize the flow, and then out the outlet 103,
Then, it is discharged via the exhaust fan 107.

The cleaning liquid is water inlet cooler 109, venturi throat nozzle 119 and absorption zone nozzle 13.
It is recirculated by a pump that feeds 7. The level of water in receiver 123 is maintained by an overflow sensing level control system.

The scrubber is set to focus its efficiency on gas cleaning, particle collection or a combination thereof. The materials of the various parts of the scrubber 100 are set to handle gas temperatures of at least 2500 degrees Fahrenheit as well as the corrosive nature of the gas.

The scrubber 100 is small in size for operational reasons, and it is adapted to provide an extended flow passage in a small area with a central passage surrounded by an annulus.

Exhaust means 170 is attached to the recirculation truck 40,
172, 174, 176, 178 and 180 (FIG. 2)
The heat generated in the trailer 40 can be dissipated. The gas exhausted by the fan 107 is exhausted using another exhaust port.

As shown in FIGS. 2 and 3, the trailer 40 may include an orifice 171 having a desk 173, in which the shape, drawings and records are provided with a heater / air conditioner 175 and an adjuster and indicator. Panel 177, 1
It can be accommodated with an orifice 171 containing 79. A water tank 181 is provided within the trailer 40 and the water contained therein is supplied to the receiver 123 of the scrubber 100 in the manner described above. Further, the air compressor 183 can be equipped for convenience of the operator of the trailer 40, and air can be blown out for purification purposes and the like as desired. A combustion air fan 185 may be provided and connected to the interior of the kiln 43 by a suitable conduit to connect the nozzle 51.
It is also possible to improve the internal combustion of the gas flowing out of it.
