Description

Wastewater room temperature evaporation and regeneration system using local heating laser}

The present invention relates to an apparatus for evaporating and regenerating wastewater at room temperature using a local area heating laser, and more particularly, by irradiating a CO2 laser to heat the local area of the rotating belt part by irradiating the wastewater, so that the wastewater is completely evaporated and dried at a high speed. Since only the residue can be left and only the local area is heated using a laser, the wastewater can be evaporated with little energy consumption to form the residue, and the residue is quickly dried to a completely dehydrated state through the laser, and the wastewater is evaporated. It relates to an apparatus for evaporating and regenerating wastewater at room temperature using a laser for local heating that can be collected and purified through a scrubber and then condensed or collected and reused in a plating bath or a washing bath.

In general, the wastewater treatment method by the evaporation method supplies wastewater containing heavy metals to an evaporation and concentrator, concentrates it to a certain concentration, crystallizes and separates it, or sends it to a drying device to finally separate heavy metals in the wastewater.

In the conventional wastewater evaporation and concentration device used in this wastewater treatment method, a number of small heat transfer tubes are mounted vertically to supply steam to the outside of the heat transfer tube, and wastewater naturally flows along the inner wall from the top of the heat transfer tube and flows down into a thin film. After receiving heat from the steam, a small amount of wastewater is evaporated and led to a condenser for condensation and discharge. The concentrated wastewater is temporarily stored in a hopper and then transferred to the top by a circulation pump so that evaporation and concentration are repeated.

Then, the wastewater concentrated to a certain concentration by the wastewater evaporation and concentrator is sent to a dryer or a crystallization facility to finally separate the solids.

However, in the conventional wastewater evaporation and concentration device, since the wastewater flowing through the inside of the heat transfer pipe in a thin film is gradually concentrated while the flow velocity is small, it is difficult to continuously maintain the heat transfer performance due to excessive scale of solids in the heat transfer pipe. There was this.

In addition, if the operator who operates the device fails to manage the concentration of wastewater and crystals are formed in the device, the heat transfer pipe is completely blocked, so the use of low-concentration wastewater with a low pollution concentration is restricted for low concentration. In order to completely separate and remove heavy metals, there is a problem of having to separately install devices such as high concentration evaporation and concentration device, crystallization facility, and drying facility, so the facility cost is excessive, and the operation time increases due to repetition of washing performed during operation. There are many difficult problems in maintaining the device as it is necessary to generate and re-treat the washing wastewater.

The prior patent uses the heat of steam to evaporate and concentrate and dry wastewater containing heavy metals, etc., so that solids of wastewater are separated and discharged in a single process, and a stirring means is installed on the rotating shaft to continuously agitate the wastewater. A configuration is described in which the heat transfer performance is maintained by removing scale of solids adhering to the heat transfer surface by rubbing against the heat transfer surface of the evaporation and concentration chamber.

However, the prior patent is a configuration in which the wastewater is dried using the heat of steam to separate and discharge solids, and there is a problem that a large-capacity facility is required because a large amount of wastewater can be treated only when a large facility is used as much as steam is used. .

In addition, since a large amount of energy is required to continuously heat the steam, there is a problem that the drying cost is increased.

In addition, since the dried solid is not completely dried, additional drying is required in order to incinerate or discharge, and thus, there is a problem that a large amount of energy is required.

1 is a view showing the overall configuration of an apparatus for evaporating and regenerating wastewater at room temperature using a laser for heating a local area according to an embodiment of the present invention, and a lower part is contained in a storage tank 10 for storing wastewater, formed in a diagonal direction. The belt part 30 is formed on the inside of the belt part 30 so that a part of the wastewater is transferred along the belt 31 through rotation of the belt 31 and is buried and transferred to the inside of the belt 31. A removal unit 35 for removing wastewater from the belt 31 and dropping it into the storage tank 10; It is formed at a certain interval on the upper side of the belt part 30, and is formed in contact with the laser heating part 40 and the belt 31 to evaporate wastewater by locally heating a part of the belt 31 with a laser, thereby heating the laser.

(1) and a scrubber (2) connected to the collecting unit (1) by a pipe to purify the steam collected by the collecting unit (1) and discharge it to the outside.

The belt part 30 allows a part of the wastewater from the storage tank 10 in which the wastewater is stored to be continuously rotated along the belt part 30, so that the dried residue by heating the local part of the laser irradiated by the laser heating part 40. To be able to form.

To this end, the belt part 30 is immersed in wastewater up to 1/3 of its total length, is formed in the shape of a conveyor belt 31 and rotates in a counterclockwise direction, and a belt rotated through the drive body 32 ( 31) is made of metal so that damage is minimized when heated through the laser heating unit 40, and wastewater is buried in the belt unit 30 through the rotation of the belt 31, and the laser heating unit along the belt unit 30 It is transferred to the local heating area through (40) and evaporated through the laser.

A removal part 35 is formed inside the belt part 30 to remove the wastewater transferred by buried inside the belt 31 from the belt 31 and drop it into the storage tank 10.

The laser heating unit 40 _{generates a CO 2} laser and is formed at a predetermined interval on the upper side of the belt unit 30 to irradiate the laser to the local heating area.

The laser heating unit 40 is the amplifier and amplified CO to increase the output to the expansion section, possible heating by amplifying the expanded CO ₂ laser power to extend the generation section, generating negative CO ₂ laser for generating a CO ₂ laser _{2 It} consists of a concentrator that focuses the laser to have a local range.

_{The reason for using the CO 2} laser in the laser heating unit 40 is to minimize damage to the belt 31 due to the laser when the surface of the belt 31 of the belt unit 30 is heated with a laser.

_{The CO 2} laser irradiated by the laser heating unit 40 heats the local heating area of the belt unit 30 in the range of 150 to 400° C. to evaporate wastewater and dry the residue to generate it.

If the belt part 30 is damaged, the replacement period of the belt 31 is shortened, and thus a problem of increasing the replacement cost occurs, and thus a CO ₂ laser is used to prevent this.

When the belt part 30 is locally heated through the laser heating part 40, the remnants of wastewater evaporated by the local heating are attached to the belt 31 and transferred back to the storage tank 10.

If this is not removed, since it is put back into the storage tank 10 along the belt 31, the scraper 70 is brought into contact with the belt 31 on the belt 31 between the area immersed in the wastewater and the local heating area to scrape off the residue. ) Is formed.

The residue may be made of a non-degradable organic substance or metal component contained in the wastewater, and the type of residue generated through a temperature controlled by the power of the _{CO 2 laser irradiated from the laser heating unit 40 is selected or all of the residues are generated.} can do.

One end of the scraper 70 in contact with the belt 31 is formed like a blade to scrape off the remnants attached to the belt 31, and a storage space is formed so that the remnants formed at the connected middle are temporarily stored, and the other side A fixing part is formed on and fixed to the fixing device.

The residue temporarily stored in the storage space of the scraper 70 can be sucked through the discharge unit and discharged to an external storage unit to be stored, and the metal components can be recycled through the discharged residue.

_{The temperature sensing unit 50 detects the temperature of the local heating area of the belt 31 heated by the CO 2} laser of the laser heating unit 40 so that the temperature falls below the set temperature range or passes through the set temperature range. When elevated, the control unit 90 _{increases or decreases the CO 2} laser power of the laser heating unit 40 so that the temperature can be adjusted within the set range.

The reason for controlling the operating speed of the discharge unit 80 is that when the rotational speed of the belt unit 30 is low, it takes a lot of heating time, so that the amount of the residue is small, so it is not necessary to discharge the residue by strong suction, This is to reduce energy consumption by weakly adjusting the suction intensity of the discharge unit 80.

On the contrary, when the rotational speed of the belt part 30 is fast and the CO ₂ laser power of the laser heating part 40 is strongly adjusted to generate the residue at a high speed, accordingly, the power of the discharge part 80 is strongly adjusted to achieve a high speed. To allow the remnants to be discharged.

The storage tank 10 provided with the belt part 30, the laser heating part 40, the scraper 70, the temperature sensing part 50, and the discharge part 80 is formed to surround the entire collection part 1 As a result, the vapor generated by the evaporation of the wastewater is prevented from being discharged without being purified by the return.
