Abstract

This invention is related to a wet gas process which would not require a spray pump, and which would allow the absorption liquid to be recovered smoothly even if the flow velocity of the gases entrained to the liquid should decrease, and a wet gas processing apparatus in which the absorption liquid collected in the liquid storage tank is sprayed in a specified direction by a liquid discharge unit consisting of spray nozzles or the like in the absorption tower. The sprayed liquid is brought into contact with the exhaust gases which are conducted into the tower, and the targeted components of the gases are absorbed and removed. This processing apparatus is distinguished by the following. The liquid storage tank for the absorption liquid comprises a pressure tank which generates a pressurized gas in the space above the surface of the collected liquid. The increased pressure of the pressurized gas is employed to spray the liquid collected in the pressurized tank from the spray nozzle unit in the absorption tower. The spray nozzle unit forms as required the overflowed or gushed absorption liquid discharge unit facing the orthogonal direction of a plurality of absorption pipes arranged in parallel crossing to said gas paths. The absorption liquid propelled by the discharge unit makes orthogonal contact with the flow of exhaust gases, which results in both atomization of the liquid and liquid-vapor contact.

The treatment method and the device thereof, in particular, relates to a wet gas treatment method and a device thereof which can effectively perform gas-liquid contact with the absorption liquid and coal or heavy oil and other burned exhaust gas. [Conventional Technology] In the past, various types of gas-liquid contact devices have been used in wet type flue gas desulfurization devices that remove harmful substances such as sulfur dioxide from the exhaust gas of coal-fired boilers. Among them, one of the gas-liquid contact devices It is, for example, a so-called liquid column type device disclosed by the present inventor in Japanese Patent Laid-Open No. 5 9-5 3 8 2 8. The device sprays an absorption liquid such as a lime suspension upward from a plurality of nozzles arranged in the absorption tower, and appears as a columnar shape. The smoke is vented in the jet to absorb sulfur dioxide containing exhaust smoke. At the same time, it can effectively remove dust such as soot. In addition, its basic structure is a schematic diagram as shown in FIG. 24 (A). A smoke exhausting section 8 is provided above the 'absorption tower 2', and a smoke exhaust introducing section 3 forming an inlet of the exhaust gas 1 is provided at the lower section. A header 190 is arranged in a plurality of rows in the lower part of the absorption tower 2. For example, a plurality of upward nozzles 4 shown in FIG. In addition, the lower part of the absorption tower 2 is configured so that the absorption liquid such as a lime suspension can be stored in the funnel-shaped liquid storage section 5 6 and returned to the absorption liquid storage tank 5 7 through the recovery pump 2 1 a. 5 Once again through the discharge pump 2 1 b flow switch valve 6 0 and the main pipe 1 9 0 to communicate with the upward nozzle 4 »This paper size applies the Chinese National Standard (CNS) A4 size (210X297 mm) III nun K ^ line (please first Read the notes on the back of this page, and write this page) Central Samples Bureau of the Ministry of Economic Affairs, Mβζ Industrial Consumer Cooperative Cooperative, printed 4386 1 9 A7 A / __B7 V. Description of the invention) In addition, a plurality of upward nozzles are formed to form the above matrix The nozzle group composed of 4 can form the absorption liquid 5 into a liquid columnar jet 5 upward. At the same time, the exhaust gas 1 introduced from the smoke exhaust introduction part 3 and vented toward the upper part of the tower follows the flow rate according to the flow rate. The jet-shaped absorption liquid 5 rises, and contacts the gas-liquid by passing through the jet 5a spreading in an umbrella shape at the top. Subsequently, the absorption liquid 5 separated with the exhaust gas 1 by the mist eliminator 6 provided on the upper part of the absorption tower 2 near the apex of the jet stream can be recovered in the absorption liquid storage tank 57. The absorption liquid 5 dropped directly to the liquid storage portion 56 is sent to the absorption liquid storage tank 57 by the recovery pump 21a. In the gas-liquid contact device configured as described above, the pump 2 1 b is operated through the flow switch valve 60 and the main pipe 19 0, and the absorption liquid 5 is sprayed upward from the upward nozzle 4 to cause the smoke exhaust introduction portion 3 side to be introduced. The exhaust gas 1 is brought into gas-liquid contact through the jet 5a, and the exhaust gas (purified gas) 7 after the treatment such as the removal of sulfur dioxide gas is led out from the smoke exhaust duct 8 on the upper side. 'Furthermore, in the above-mentioned technique of spraying the absorption liquid 5 upward, not only does the absorption liquid 5 require a long round-trip (rise, fall) time The liquid 5 forms a droplet 1 so that the gas-liquid contact effect can be increased. When the sulfur dioxide gas contained in the exhaust gas is small, only the height of the liquid column can be changed to perform economic operation. In addition, the absorption liquid flows down to 下Compared with the so-called filling method in which a gas is contacted, the tower filled with a grid has many advantages, such as preventing the fluid passage from being blocked. In the case of the above-mentioned technology, the injection pump 2 1 b is operated, and the absorption liquid 5 stored in the liquid storage portion 56 or the absorption liquid storage tank 57 is circulated on the main pipe 1 90 side, and is set by the nozzle 4 The spray pressure will spray the absorption liquid 5 IIIIII Order II 1 (1 f ^ (Please read the note on the back first: this page) The paper size is in accordance with the Chinese National Standard (CNS) A4 specification (2 丨 〇297mm)- 5 * Printed by the Consumers' Cooperative of the Central Bureau of Standards, Ministry of Economic Affairs 4 386 1 9 at _. ____B7 V. Description of the invention) To a predetermined height》 Furthermore, the injection pump 2 1 b in this figure is shown as a single component to simplify the description. * However, a plurality of pumps are actually used, so there will be compact equipment and equipment costs. , Reduction of running costs and other issues. In addition, in order to improve the efficiency of gas-liquid contact between the exhaust gas and the absorption liquid, it is necessary to provide a plurality of nozzles for atomizing the absorption liquid that contacts the exhaust gas. Therefore, there must be a plurality of matrix-shaped nozzles as shown in No. 2 4 (B) 囵. There is a problem that the nozzle group for absorbing liquid is discharged, etc., and the load on the equipment is increased. Therefore, for example, in German Patent No. DE 1-1 7 6 9 9 4 5 or Japanese Patent No. Hei 9-50779 No. 2, a tank for storing and supplying the suspension liquid for circulating the nozzle is provided, and the liquid level of the tank is set. It is set higher than the nozzle ejection position, so that the absorption liquid ejected by the nozzle is separated into absorption liquid and gas with the gas in the upper part of the absorption tower. The separated absorption liquid can be kept in the tank and the gravity difference of the liquid level of the tank can be used. The suspension is sprayed out through the nozzle, and the suspension of the nozzle can be sprayed and circulated by using the difference in gravity without using a jet pump. However, in the related art described above, although the liquid level of the tank storing the absorption liquid is based on the condition that the position is higher than the ejection position of the nozzle in the absorption tower, the absorption tower generally has a considerable height, and the liquid at a position higher than the height is set. When facing the surface, there are disadvantages such as that the height of the groove must be increased. In addition, in the gas scrubbing device of the flue gas desulfurization device, the gas generation source of the boiler and the like generally have load fluctuations. Therefore, in any of the above devices *, when the gas flow rate is reduced, the gas flow rate will not be able to attract and absorb Liquid · Therefore, the gas-liquid contact between the absorption liquid and the gas stream cannot be smoothly performed, and not only the sulfur dioxide gas or dust contained in the exhaust gas can not be effectively removed, but also I — ^ n I ^ 11 H] ^ ( Please read the precautions on the reverse side of this page before writing this page.) The paper scale is applicable to China National Standard (CNS) A4 specifications (210X297 mm) -6- 438619 A7 B7 V. Description of the invention 6) * Absorbent liquid, in other words, in The circulation of the absorption liquid in the tank is difficult, and as a result, the liquid level in the tank is gradually lowered. Finally, it will be difficult to absorb the liquid with its own weight. 0 In addition, in any of the above-mentioned devices, the discharge speed of the absorption liquid, in other words, the discharge height It increases and decreases in proportion to the flow rate of the exhaust gas. Therefore, as shown in Figure 13, T1 when the inside of the absorption tower rises to T2 when it falls. When the combustion capacity on the burner side is small, the exhaust gas is reduced. It is not possible to increase the spraying height of the absorption liquid sprayed from the nozzle to a level higher than the reference level. As a result, almost the entire amount of the spray flow cannot reach the defogging gas provided at the top of the tower and falls to the liquid storage part in a waist-folded state. In many cases, the absorption liquid stored in the liquid storage unit cannot be used. Therefore, in the conventional device, since the absorption liquid can be continuously circulated, the size of the liquid storage portion 56 must be increased, or only the recovery pump 2 1 a for the return flow should be prepared for a large capacity when the absorption tower 2 is raised and lowered. Material, but it will cause unnecessary increase in equipment costs. In addition, the spray (liquid droplets) of any of the above-mentioned devices that also absorb the target components such as sulfur dioxide gas with the exhaust gas impacts the curved plate of the spray purifier on the upper part of the absorption tower and falls into the absorption tower to continuously circulate the absorption liquid, but As in the conventional device described above, when the gas flow rate in the tower is generally 4 to 5 m / s, the mist eliminator can be used to supplement it. However, in recent years, due to the improvement of processing capacity and space saving, it is necessary to increase the gas flow rate in the tower. To e.g. 5. Requirement for high speed above 5m / s》 +, once the gas speed is increased to 5. Above 5 m / s +, the droplets in this part of the mist eliminator cannot be drained out, but with the gas and the absorbed droplets are discharged out of the tower at the same time, released into the atmosphere 1 and sent to the processing equipment in the later stage Waiting is not ideal. This paper size applies to Chinese national standards (CNS > A4 size (2 丨 0X297 mm) ------------ installation ------ order ------ line {please first Read the note on the back ^^ Xiang Shengbu write this page) Printed by the Central Government Bureau of the Ministry of Economic Affairs, printed by the Shellfish Consumer Cooperative 4 3 8 6 1 9 , 5. The flow velocity of gas above 5m / s will greatly increase the amount of absorbed liquid reaching the mist eliminator with the gas. Therefore, the liquid that should fall from the mist eliminator cannot effectively fall, and a spiral droplet is formed at the entrance of the mist eliminator. The retention phenomenon (scattered absorption liquid storage area) occurs, which significantly reduces the spray removal performance. The reduction of the spray removal performance is caused by the spray (liquid droplets) being scattered again with the exhaust gas from the scattered absorption liquid storage area, so the Exhaust from the flue spray for exhaust is increased. [Explanation of the Invention] The present invention has been made in view of the shortcomings of the above-mentioned conventional technology, and provides an invention for a wet gas treatment that does not require the use of a jet pump or can smoothly recover the absorption liquid even when the gas flow rate is reduced with the absorption liquid. . Another object of the present invention is to provide an energy-saving method that does not require the use of a conventional upward nozzle, or does not require a large amount of power. It can reduce the burden on the nozzle equipment, etc., can achieve low cost, and can effectively make gas-liquid contact. The invention of wet gas treatment is aimed at. Another object of the present invention is to provide a wet exhaust gas treatment invention that does not needlessly increase the size and capacity of the liquid storage section and can effectively solve the problems caused when the above-mentioned exhaust gas flow rate is reduced. Another object of the present invention is to provide an exhaust gas treatment invention that can maintain the liquid column height of the absorption liquid above the reference level even when the flow rate of the exhaust gas introduced by the low-capacity combustion decreases when the absorption tower rises or is closed. 》 Another object of the present invention is to provide the exhaust gas contained in the absorption tower from the absorption tower even when the exhaust gas in the absorption tower has a high internal velocity (current-carrying velocity) (please read the note on the back first ^ # 朱 写 页) This paper size applies to Chinese National Standard (CNS) A4 specification U10X297 mm) _ 8 _ Printed by the Bayer Consumer Cooperative of the Central Bureau of the Ministry of Economic Affairs 3 86 1 9 A7 _B7___ V. Description of the invention (6 ).  It is an object of the invention related to wet exhaust gas treatment that the amount of spray (liquid) to be discharged is as small as possible. In order to solve the above-mentioned problems, the present invention is described in item 1 of the scope of the patent application. * The absorption liquid stored in the absorption liquid storage portion is directed from the absorption liquid outflow portion such as a nozzle in the absorption tower toward a predetermined direction (not only upwards and at the same time). Including a horizontal, downward) jet stream, which makes the jet stream contact the exhaust gas gas-liquid ventilated in the absorption tower, and absorbs / removes the target component in the exhaust gas in a wet gas treatment device. It is characterized by generating pressurized gas. The pressure tank forms the absorption liquid storage portion above the storage liquid surface, and uses the pressure of the pressurized gas to form the absorption liquid stored in the pressure tank from the nozzle portion in the absorption tower. According to the invention, the discharge volume of the absorption liquid of the nozzle can be determined by the pressured area of the pressure tank and the pressure of the pressurized gas. Moreover, the load of the combustion device such as a boiler can be changed, even when the gas flow rate in the absorption tower is changed. The pressure in the pressure tank can be controlled to correct this fluctuation direction I, so that a certain nozzle spraying liquid can be maintained at a substantially constant height. If the body flow rate is decreased, the absorbent can be recovered smoothly. In addition, the pressure of the gas in the pressurized tank can be averaged from the discharge amount of the absorption liquid from the tank, and the supply amount of the absorption liquid to the tank and the gas injection in the tank can be controlled to a predetermined pressure. Invention * Instead of directly absorbing the absorption liquid with a jet pump, pressurized gas such as compressed air is added to the pressurized tank. In other words, it is not necessary to use multiple pumps, only the pressurized pump and the supply of pressurized gas in it A gas compression source such as an air compressor is sufficient, so the device can be miniaturized and the equipment cost can be realized (please read the note on the back page of the first page).  The paper size of the edition is applicable to the National Solid Standard (CNS) 6 4 this grid (210X297 gong) -9-Printed by the Shell Consumer Cooperative of the Central Samples Bureau of the Ministry of Economic Affairs 4 3 8 6 1 9 A7 B7 V. Description of the invention & ) Reduction of transfer costs, etc. Also. Even if the absorption liquid supply nozzle is an upward upward device, it is not necessary to locate the upward nozzle at the upper part of the liquid surface of the pressure tank, and a low pressure tank can be set and can be freely arranged. In addition, as described in item 2 of the scope of the patent application, when the target component in the absorption liquid to be absorbed / removed is sulfur dioxide (S02), the pressurized gas is an oxygen-containing gas, and this oxygen-containing gas Spray into the storage liquid at the bottom of the pressure tank. It is sprayed from the nozzle to make contact with the gas-liquid of the exhaust gas. When the lime-containing suspension absorbent that absorbs S 0 2 is stored in the pressurized tank. • The sulfur dioxide can be oxidized due to the contact with the oxygen-containing gas. Calcium dihydrate (gypsum) ^ In addition, the present invention is a wet gas processing apparatus provided with an upward nozzle that sprays the absorption liquid above the nozzle portion in the absorption tower, as described in item 3 of the patent application scope, to generate pressurized air. The pressure tank forms the absorption liquid storage part in the space above the storage liquid surface. On the one hand, the recovery liquid part that can recover and absorb the above-mentioned target component is arranged in an absorption tower higher than the storage liquid level in the pressure tank. It is also possible to return the absorption liquid of the recovery unit to the outlet end of the communication pipe on the pressurizing side, and position the liquid in the storage liquid in the pressurizing tank. According to the present invention, the absorption liquid for absorbing / removing the target component is recovered to the side of the pressurized tank through the recovery unit, and a reusable absorption liquid is formed. In addition, when a communication pipe for recovering the absorption liquid is opened in the recovery section toward the closed space inside the pressurized tank, the gas pressure in the space is diffused through the communication pipe into the absorption tower, and the function of the pressurized tank cannot be maintained. Therefore, the present invention refers to the * binding line for returning the absorption liquid to the pressure tank side by the recovery part (please read the precautions on the back first to write this page) This paper uses China National Kneading Ratio (CNS) A4 specifications { 210 × 297 mm) -10- 43 86 1 9 A7 B7_____ V. Description of the invention fe) The opening of the outlet end of the communication tube is positioned in the storage liquid in the above pressure tank, so that the pressure tank can be formed by using the absorption liquid in the communication tube. The gas pressure is sealed, and the recovery part is arranged at a predetermined position in the absorption tower higher than the storage liquid level in the pressure tank. Therefore, the liquid level in the communication tube can be raised to the inside of the pressure tank through the communication tube of the recovery part. Position of pressure balance. In addition, by setting the height difference of the communication pipe, the position of the recovery section and the pressure in the tank so that the liquid level in the communication pipe is lower than the position of the recovery section, the circulation of the absorption liquid from the recovery device to the pressure tank can be performed. The gas pressure sealing of the pressure tank can be performed by using the absorption liquid in the communication pipe. Furthermore, according to the present invention, when the absorption liquid is sprayed upward in the absorption tower and the absorption liquid is recovered by the recovery part provided in the upper part of the absorption tower, It falls to the bottom of the absorption tower, so only the above recovery part cannot recover 100%. Therefore, when the liquid level stored in the bottom of the absorption tower reaches a predetermined amount or more, it can be returned to the pressure tank by a low pressure pump. A part of the liquid is discharged simultaneously with the gas, so it can be replenished by the raw material supply pipe. In addition, the invention described in item 4 of the scope of patent application is to introduce the absorption liquid stored in the absorption liquid storage tank into the absorption tower, and make the absorption liquid flow with the exhaust gas flow rate along the exhaust passage in the absorption tower and The exhaust gas is in a gas-liquid contact and absorbs / removes the target component in the exhaust gas. The wet gas processing device is characterized in that it is provided on a plurality of absorption liquid pipes arranged substantially across the direction of the exhaust passage. The direction in which the liquid intersects with the above-mentioned exhaust gas venting direction * More specifically, an absorption liquid outflow portion in the form of an overflow or a discharge flow is formed in a substantially lateral direction, and the absorption liquid flowing out of the outflow portion contacts the exhaust gas flow in a cross-contact manner. Micronization is performed for gas-liquid contact.

Description of the invention) That is, the supply of the absorbent liquid of the present invention is to form an absorbent liquid that overflows or spouts in a generally transverse direction instead of the conventional one. Most nozzles are arranged in a matrix shape (see Figure 24 (B)), and the absorption liquid flowing out of the outflow part is atomized by the cross-contact with the above-mentioned exhaust gas stream to make gas-liquid contact. The above-mentioned invention is, for example, as described in item 5 of the scope of patent application, one or more sections (including the upper and lower zigzag arrangement) of the absorption liquid pipe group are arranged along one or more planes that substantially cross the exhaust path. It is preferable that the above-mentioned exhaust gas flow can be conducted in a gap portion between adjacent pipes of the pipe group arranged in the row. In addition, the structure of the absorbent pipe is as described in item 6 of the scope of patent application. At the same time as the above-mentioned open water-conducting tubular member constitutes the absorbent pipe, the water-conducting tubular member may be provided in a direction that intersects the ventilation direction. The means for forming the overflow in the substantially horizontal direction is also described in item 7 of the scope of the patent application. The upper closed tubular member constitutes the absorption liquid pipe, and can also be connected with the exhaust gas flow through the absorption liquid pipe. A slit-like opening or a plurality of small hole rows are provided along the tube axis direction on the surrounding surface of the part. According to the above-mentioned invention, it is only necessary to make the absorption liquid overflow or flow out in a substantially horizontal direction toward the gap portion side between the adjacent pipes, and the effect of reducing the equipment cost can be obtained. In addition, as described in item 8 of the scope of the patent application, the absorption liquid supply to the absorption liquid tube may also constitute the absorption liquid supply source using gravity.

Description of the invention) In addition, the present invention is provided with absorption liquid pipes in which the exhaust passages are arranged in a plurality of predetermined gaps. As a result, the velocity of the exhaust gas can be increased at the gaps, and the speed can be increased. In the present invention, the absorption liquid flows out to the above-mentioned space portion where the exhaust flow is accelerated, and contacts the high-speed rising exhaust flow in a cross shape. Therefore, the absorption liquid is disturbed by the high-speed energy generated by the exhaust gas, and is formed into particles. In addition, the negative pressure caused by the rapid compression and expansion of the exhaust gas in the gap portion of the exhaust gas can simultaneously rapidly disperse the tiny droplets of the absorption liquid in the exhaust gas, and promote effective gas-liquid contact such as atomization of the absorption flow and the like. Supply of absorption liquid | The liquid column of the conventional liquid column type can be more effectively and efficiently absorbed in a short period of time, compared with the gas-liquid contact completed when the liquid column is spread out at the top, and it is discharged with the exhaust gas. / Remove the target component 0 in the exhaust gas, and make gas-liquid contact with the gaps between adjacent absorption liquids, and the outflow liquid film or linear flow of absorption liquid is sprayed out of the gaps, so it is not necessary For example, the conventional device is equipped with high-density nozzles, which significantly contributes to cost reduction. Furthermore, the above-mentioned liquid absorption pipe is constituted by a water-conducting tubular member. Especially when the above-mentioned serrated water-conducting pipe member is arranged, the exhaust passage is interposed between the drainage tubular members, so the exhaust system of the passage is compressed and expanded. Waiting for step I can promote effective atomization and minute droplet formation of the open surface of the drainage pipe member. In addition, as described in item 9 of the scope of the patent application, the present invention sprays the absorption liquid stored in the absorption liquid storage portion from a nozzle portion in the absorption tower in a predetermined direction (except for the upward direction and includes the lateral direction and the downward direction). The jet flow is in contact with the exhaust gas-liquid ventilated in the absorption tower, and the wet gas treatment method that absorbs / removes the target component in the exhaust gas is characterized by: (Please read the note item # 4 on the back first to write this page ) This paper size is applicable to China ’s Standards for Household Standards (CNS) M (210X2? 7mm) -13- Printed by the Shellfish Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs 43 86 1 9 A7 B7 The exhaust gas passage ventilated in the absorption tower is controlled in a width region corresponding to the discharge amount, and the gas passage region of the exhaust gas passage can be adjusted. Therefore, according to the present invention, it is possible to reduce the gas flow in the absorption tower by changing the load of a combustion device such as a boiler. When the flow rate of the exhaust gas passage is reduced according to this ratio, the gas passage area of the controlled gas inflow area is controlled in accordance with the decrease in the flow rate. The gas flow rate is constant * As a result, the absorption liquid spraying height of the nozzle can be maintained at a substantially constant level. As a result, the absorption liquid can smoothly contact the absorption liquid with the gas and liquid of the gas with the flow velocity of the gas, which can not only effectively remove the smoke in the exhaust. The contained sulfur dioxide gas or dust can smoothly recover the absorption liquid in the upper part of the absorption tower * In other words, the circulation of the absorption liquid in the tank can be smoothly performed. At this time, as described in item 10 of the scope of patent application, stop from the above The jet of the absorption liquid from the nozzle portion where the gas flows into the blocked area can save unnecessary pump driving power, etc., and at the same time, prevent unnecessary absorption liquid circulation.

Description of the Invention) In the first picture, the exhaust gas from a combustion device such as a boiler 1 It is introduced into the smoke exhaust introduction part 3 provided in the lower part of the absorption tower 2. The introduced exhaust gas 1 is in contact with the absorption liquid 5 supplied by the absorption liquid supply nozzle 4 provided in the lower part of the absorption tower 2 to move the target component in the gas from the gas to the absorption liquid 5. In this case, the combination of the target component in the gas and the absorbing solution means that the target component is soluble in the absorbing solution and dust. For example, in this embodiment, the soluble target component of the absorbing liquid is sulfur dioxide (SO2), and the absorbing liquid is a suspension of limestone containing an absorbing agent. In addition, the nozzle is an upward nozzle 4 in the present embodiment. * The absorption liquid 5 is sprayed upward from the upward nozzle 4 so that the exhaust gas 1 introduced by the smoke exhaust introduction unit 3 is absorbed by the nozzle 4. The liquid jet 5 a is in gas-liquid contact with the jet passing through the absorption liquid 5. A mist eliminator 6 is arranged on the upper part of the absorption tower 2 near the apex of the jet stream, and the absorption liquid 5 accompanying the gas 1 is removed by the mist eliminator 6. In the absorption tower 2, the target component is removed from the absorption liquid 5, and the purified gas 7 after the absorption liquid 5 is removed by the mist eliminator 6 is finally discharged into the atmosphere from the smoke exhausting section 8 or, if necessary, not shown in the figure. Streaming machine. On the other hand, a recoverer 9 with an upper opening is arranged around the side wall of the absorption tower 2 below the mist eliminator 6, and the absorption liquid 5 captured by the mist eliminator 6 is recovered by the recoverer 9 and passed through the communication pipe 10 Drop into the pressure tank 1 1. Therefore, the height of the absorption liquid 5 sprayed from the absorption liquid supply nozzle 4 is pushed by the flow rate of the exhaust gas 1 to set the pressure and communication pipe of the pressure tank 11 that can rise above the position of the recovery device 9 10 its upper end is open at the bottom of the recycler 9, the connecting pipe 10 II ί ί I ni— II line (please read the precautionary note on the back first < write this page) This paper's standard is applicable to China National Standards (CNS) Regulation 8 < Grid (210X297 mm) -28 · 438619 A7 B7 Printed by the Central Consumers Bureau of the Ministry of Economic Affairs, Printed by the Consumers Cooperative Cooperative, V. Description of the invention β) is opened from the top of the pressure tank 11 and is often submerged into the tank 11 The position in the absorption liquid inside is sealed by the communication pipe 10 with the gas of the pressure tank 11. That is, the absorption liquid 5 recovered by the recoverer 9 flows from the communication pipe 10 toward the pressure tank 11, but at this time, compressed air is generated in the upper closed space 1 1 a inside the pressure tank 11. The pressure of the gas will cause the absorption liquid 5 in the pressure tank 11 to flow back, and raise the liquid level in the communication pipe 10 to a position that is in equilibrium with the pressure in the pressure tank 1 1. And set the level difference of the communication pipe 10, The position of the recoverer 9 and the internal pressure of the tank 11 make the liquid level in the communication pipe 10 lower than the position of the recoverer 9 so that the recoverer 9 can continue to circulate the absorption liquid into the pressure tank 11 and can borrow the liquid. The pressure tank 11 is hermetically sealed against the absorption liquid 5 in the communication tube 10. The bottom of the pressure tank 11 is provided with a gas nozzle 13 connected to the air compressor 12, which can inject air pressurized by the storage and discharge liquid, in other words, an oxygen-containing gas. This pressurized gas has two functions. The first is to maintain the pressure of the upper closed space I ia in the pressurized tank 11, and the second is the suspended absorption liquid 5 containing the limestone that is in contact with the gas-liquid to absorb S 〇 2. Contact with the above oxygen-containing gas oxidizes S0 to produce calcium sulfate dihydrate (gypsum). The absorption liquid 5 stored in the pressure tank 11 is under the pressure of the closed space 1 1 a in the pressure tank 11 The absorption liquid supply nozzle 4 in the absorption tower 2 is circulated through a flow control valve 15 that controls the supply flow of the absorption liquid supply pipe 14 and the absorption liquid 5. * Next, the structure of the pressure tank 11 will be described below. At the top of the pressure tank 11 is a pressure control valve 16 that controls the atmospheric open pipe 17 and the pressure in the tank 11 or supplies raw materials such as neutralizers on the side wall of the tank --------- ^-( Please read the notes on the back first. . .

Description of the invention) The pipes 1 and 8 are respectively installed by a drainage recovery pump 2 1 and a drainage recovery pipe 20 for recovering the absorption liquid 5 from the liquid storage part 5 6 provided at the bottom of the absorption tower 2. On the other hand, an extraction pipe 19 is installed at the bottom of the tank 11 so that gypsum and the like produced during the above-mentioned oxidation of S02 can be pulled out. The reason for constituting the pressure tank 11 is as follows.

In addition, according to this embodiment, the control of the jet pressure of the absorption liquid can be obtained by the pressure of the pressure tank. The pressure is controlled arbitrarily, so not only does the pump need not be pressurized, but a certain amount of absorption liquid can be supplied regardless of the liquid surface of the pressure tank. In addition, when the absorption tower 2 rises or is closed, as shown in FIG. 13, the exhaust gas flow rate will be less than the above-mentioned load speed, so the jet 5 a of the absorption liquid 5 ejected from the nozzle 4 is not lifted by the exhaust gas 1 to the upper part of the absorption tower. Almost the entire amount of the discharged absorption liquid 5 drops to the lower liquid storage portion 56 (indicated by symbol 5b).

However, in the above-mentioned conventional technology, when the absorption tower is raised and closed, the exhaust gas does not pass through the absorption tower, and therefore there is a problem that the sulfur dioxide gas or dust contained in the exhaust gas cannot be removed without performing exhaust gas treatment. Also, when the light oil with low emissions such as S02 and coal dust is burned without avoiding the above problems, problems such as high fuel costs may occur. Fig. 14 shows a fifth embodiment in which the conventional bypass passage 72 is effectively used, and the same effect as in the fourth embodiment can be improved. An exhaust source such as a boiler or a burner and an exhaust gas such as a chimney are connected. The main channel 7 4 of the atmospheric emission part utilizes the flow velocity of the exhaust gas to make contact with the gas-liquid contact with both of the absorption liquid 5 by using a gas-liquid separation system.
