Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a reactor spray tower. Background Art

[0002] A reactor spray tower, also known as a scrubber, absorption tower, or exhaust tower, is a device that purifies exhaust gas through gas-liquid contact. Its working principle is to use chemical reactions or solubility to remove harmful substances from exhaust gas, bringing it up to national emission standards.

[0003] In some industrial production processes, a large amount of waste gas will be discharged. During the emission of waste gas, in order to ensure that the waste gas meets the emission standards, a spray tower is generally used to treat the waste gas.

[0004] During the treatment process in the reactor spray tower, exhaust gas is first discharged into the reactor spray tower. Water is then sprayed through the spray device to form a water mist. The water mist envelops the smoke particles and filters them through the filter. The filtered water is then discharged and recycled. During the water mist formation process, if the water mist is not sealed tightly or the formed water mist is too thin, some exhaust gas will pass through the water mist and be discharged from the exhaust port, preventing some exhaust gas from being filtered and settled, causing pollution and affecting the filtration efficiency of the reactor spray tower.

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the following will combine the technical scheme in the embodiments of the utility model to make clear and complete description, obviously, the described embodiments are partial embodiments of the utility model, not all embodiments.

[0027] In the description of the utility model, it is understood that the orientation or positional relationship indicated by the terms "center", "transverse", "longitudinal", "front", "back", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, therefore, it cannot be understood as a limitation on the protection scope of the utility model. When a component is referred to as "fixed to" another component, it can be directly on the other component or there can be a middle component. When a component is referred to as "connected to" another component, it can be directly connected to the other component or there can be a middle component. When a component is referred to as "provided on" another component, it can be directly provided on the other component or there can be a middle component. The terms "vertical", "horizontal", "left", "right" and the like used in this paper are only for illustrative purposes.

[0028] As Figures 1 to 6As shown, the utility model is a reactor spray tower, comprising: a tower body 1, a gas delivery mechanism for delivering exhaust gas into the tower body 1, a spray mechanism for spraying the exhaust gas, and an air outlet mechanism for discharging the purified gas.

[0029] The gas transmission mechanism includes: an air collecting pipe 7 fixedly installed in the tower body 1, an air inlet pipe 6 and an air guide pipe 8 connected to the annular pipe 12; the top end of the air guide pipe 8 is plugged into the bottom of the filter screen.

[0030] Purification liquid is stored in the tower body 1, and the liquid level of the purification liquid is flush with the top of the filter cartridge 9. At this time, the exhaust gas enters the gas collecting pipe 7 through the air inlet pipe 6 and is transported to the filter cartridge 9 through multiple air guide pipes 8. A one-way valve is installed on the air guide pipe 8 to prevent the purification liquid from flowing back through the air guide pipe 8. The gas entering the filter cartridge 9 contacts and reacts with the purification liquid, thereby purifying the exhaust gas.

[0031] The spray mechanism includes: a mounting plate 25 fixedly mounted in the tower body 1, with a plurality of through holes formed on the mounting plate 25 to facilitate the upward discharge of filtered gas; an annular tube 12 fixedly mounted at the bottom of the mounting plate 25; a hose 13 connected to the annular tube 12; an atomizing nozzle 14 connected to the hose 13; a pump body 10 connected to the annular tube 12; a liquid inlet pipe 11 connecting the pump body 10 and the tower body 1; and a swinging assembly for driving the atomizing nozzle 14 to swing.

[0032] Since the waste gas entering the filter cartridge 9 easily forms bubbles and bursts when floating to the surface of the purified liquid, this part of the waste gas cannot react with the purified liquid in the filter cartridge 9. At this time, by starting the pump body 10, the purified liquid can be sucked out through the liquid inlet pipe 11 and transported to the annular pipe 12, and then atomized and sprayed out after passing through the hose 13 and the atomizing nozzle 14, so that the waste gas with burst bubbles contacts the atomized purified liquid, thereby purifying this part of the waste gas, making the waste gas purification more comprehensive and improving the waste gas purification effect.

[0033] In addition, since several atomizing nozzles 14 are evenly distributed in a ring shape at the bottom of the annular tube 12, the purified liquid in the annular tube 12 can be evenly sprayed out, and the water mist sprayed by the atomizing nozzles 14 is evenly distributed in the inner cavity of the tower body 1, thereby fully contacting the exhaust gas from the burst bubbles, further improving the exhaust gas purification effect.

[0034] The swing assembly includes: a dual-axis motor 3 fixedly installed in the tower body 1, a long shaft 5 fixedly connected to the output shaft of the motor, a cylinder 15 fixedly sleeved on the long shaft 5, a ring 16 sleeved on the cylinder 15, a connecting rod 18 hingedly installed between the ring 16 and the atomizing nozzle 14, a limiting tube 19 plugged into the ring 16, a limiting rod 20 movably installed in the limiting tube 19, the top of the limiting rod 20 is fixedly connected to the mounting plate 25, an annular plate 21 fixedly installed on the end of the limiting rod 20, and a bull's eye ball 17 rotatably installed in the ring 16; a guide groove is provided on the cylinder 15, the guide groove consists of two U-shaped grooves in opposite directions, and the two U-shaped grooves in opposite directions are arranged to penetrate each other, and the bull's eye ball 17 rolls in the guide groove.

[0035] When the pump body 10 is started, the dual-axis motor 3 is started, and the dual-axis motor 3 drives the long shaft 5 to rotate, and the long shaft 5 drives the cylinder 15 to rotate. The cylinder 15 drives the bull's eye ball 17 to make axial reciprocating motion along the path of the guide groove, thereby driving the ring 16 to move. Through the mutual cooperation of the limiting rod 20 and the limiting tube 19, the ring 16 can be limited. Therefore, when the ball moves, the ring 16 makes up and down reciprocating motion, and the ring 16 drives the connecting rod 18 to move, and the connecting rod 18 drives the atomizing nozzle 14 to move.

[0036] When the circular ring 16 moves upward, it can drive the connecting rod 18 to move upward, and drive the adjacent atomizing nozzles 14 to gather inward through the connecting rod 18. When the circular ring 16 moves downward, it can drive the connecting rod 18 to move downward, and drive the adjacent atomizing nozzles 14 to expand outward through the connecting rod 18. Therefore, the atomizing nozzles 14 can swing back and forth inward and outward through the up and down movement of the circular ring 16.

[0037] The swing of the atomizing nozzle 14 increases the atomization range of the purification liquid, thereby allowing the exhaust gas to fully contact with the water mist, further making the exhaust gas purification more comprehensive and improving the exhaust gas purification effect.

[0038] The air outlet mechanism includes: a fan blade 4 fixedly mounted on the long shaft 5 and a protective net 2 fixedly mounted on the tower body 1 .

[0039] When the dual-axis motor 3 is started, the fan blades 4 can be driven to rotate, thereby blowing the purified gas upward and discharging it to the outside of the tower body 1 through the mesh of the protective net 2. The setting of the protective net 2 can facilitate the discharge of the purified gas on the one hand, and prevent foreign matter from falling from the top of the tower body 1 into the tower body 1 on the other hand, causing damage to the various components inside the tower body 1.

[0040] The filter cylinder 9 is fixedly installed in the tower body 1, the discharge pipe 26 is communicated with the filter cylinder 9, and the cleaning mechanism is used for cleaning the filter cylinder 9.

[0041] Since the solid particles are contained in the waste gas, the solid particles are retained in the purification liquid after entering the filter cylinder 9, at this time, the particles in the purification liquid are filtered through the setting of the filter cylinder 9, and the filtered purification liquid is transported into the annular pipe 12 through the liquid inlet pipe 11 for use, so that the particles are prevented from blocking the atomizing nozzle 14.

[0042] When the long shaft 5 rotates, the sliding bar 23 is driven to rotate, the sliding bar 23 drives the movable pipe 22 to rotate, and the movable pipe 22 drives the stirring plate 24 to rotate; at the same time, when the circular ring 16 moves up and down, the limiting pipe 19 is driven to move up and down, the limiting pipe 19 drives the annular plate 21 to move up and down, the annular plate 21 drives the movable pipe 22 to move up and down, and the movable pipe 22 drives the stirring plate 24 to move up and down, so that the stirring plate 24 realizes reciprocating movement up and down while rotating.

[0043] Through the reciprocating movement up and down while rotating of the stirring plate 24, the stirring range of the stirring plate 24 is expanded, on the one hand, the waste gas and the purification liquid are stirred, so that the waste gas and the purification liquid are fully contacted, and the purification effect is improved, and on the other hand, the bubbles formed by the waste gas are broken, so that more waste gas and the purification liquid are reacted, the waste gas is purified more thoroughly, and the purification effect is further improved.

[0044] The bubbles formed by the waste gas are broken through the stirring plate 24, so that the bubbles broken at the liquid surface of the purification liquid are reduced, so that the atomizing liquid is contacted with a small amount of waste gas, and the purification effect of the waste gas is ensured.

[0045] The valve is installed on the discharge pipe 26, and the sealing door is installed on the tower body 1, when the purification liquid needs to be replaced, the air inlet mechanism stops air inlet, at this time, the purification liquid in the tower body 1 is discharged through the discharge pipe 26 by opening the valve, at this time, the discharge pipe 26 can be connected with the pipeline, so as to facilitate the discharge of the purification liquid, and the double-shaft motor 3 is started, so that the purification liquid is discharged while the stirring plate 24 reciprocating moves up and down while rotating, so that the particles attached to the inner wall of the filter cylinder 9 are moved with the stirring of the purification liquid, so as to facilitate the discharge of the used purification liquid together with the particles.

[0046] After the purification liquid is discharged, the discharge pipe 26 is connected with the equipment for storing the purification liquid, and the new purification liquid is transported into the tower body 1, so as to prepare for subsequent use.

[0047] In this application, the waste gas can be purified in multiple ways by setting up the spraying mechanism, the filter cartridge 9 and the cleaning mechanism, thereby achieving sufficient purification of the waste gas and improving the purification effect of the waste gas.

[0048] Working principle: When in use, the tower body 1 stores purified liquid, and the liquid level of the purified liquid is flush with the top of the filter cartridge 9. At this time, the exhaust gas enters the gas collecting pipe 7 through the air inlet pipe 6 and is transported to the filter cartridge 9 through multiple air guide pipes 8. A one-way valve is installed on the air guide pipe 8 to prevent the purified liquid from flowing back through the air guide pipe 8. The gas entering the filter cartridge 9 contacts and reacts with the purified liquid, thereby purifying the exhaust gas. Since the exhaust gas entering the filter cartridge 9 easily forms bubbles and bursts when floating to the surface of the purified liquid, this part of the exhaust gas cannot react with the purified liquid in the filter cartridge 9. At this time, the purified liquid can be pumped out by starting the pump body 10. It is sucked out through the liquid inlet pipe 11 and transported to the annular tube 12, and is atomized and sprayed after passing through the hose 13 and the atomizing nozzle 14, so that the exhaust gas with burst bubbles comes into contact with the atomized purification liquid, thereby purifying this part of the exhaust gas, making the exhaust gas purification more comprehensive and improving the exhaust gas purification effect; in addition, since several atomizing nozzles 14 are evenly distributed in an annular shape at the bottom of the annular tube 12, the purification liquid in the annular tube 12 can be evenly sprayed, so that the water mist sprayed by the atomizing nozzle 14 is evenly distributed in the inner cavity of the tower body 1, thereby fully contacting the exhaust gas with burst bubbles, further improving the exhaust gas purification effect.
