Description

A desulfurization wastewater discharge system Technical Field

[0001] This invention relates to the field of desulfurization technology, and in particular to a desulfurization wastewater discharge system. Background Technology

[0002] The existing desulfurization wastewater discharge system cannot meet the zero-emission requirement and may trigger environmental incidents at any time. At the same time, not discharging desulfurization wastewater will threaten the safe operation of the unit's desulfurization system, leading to low desulfurization efficiency, increased power consumption and limestone powder consumption, and may even cause serious environmental incidents and shutdowns.

[0003] Furthermore, during the operation of the desulfurization absorption tower, particle deposition in the slurry can clog pipes, flanges, and accessories, affecting energy transmission and conversion, increasing the tower's resistance and pressure drop, and reducing desulfurization efficiency. Particle deposition can also lead to equipment corrosion and wear, affecting the equipment's durability and lifespan. To prevent particle deposition, an agitator needs to be installed on the side of the desulfurization absorption tower, with multiple bearings mounted on the agitator shaft. To ensure the bearings operate normally, they need to be lubricated quickly and easily to guarantee the stable operation of the agitator shaft.

[0033] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0034] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0035] Example 1

[0036] Referring to Figure 1, which is the first embodiment of the present invention, this embodiment provides a desulfurization wastewater discharge system, which includes a desulfurization device. The desulfurization device is used to desulfurize target impurities to obtain desulfurization wastewater. The desulfurization treatment adopts wet desulfurization, and desulfurization wastewater is generated after desulfurization by the desulfurization device.

[0037] At least one spraying device is provided, which is used to spray desulfurization wastewater onto a corresponding target area. Each target area is provided with a corresponding spraying device, which may be a spray mist gun.

[0038] Furthermore, the system also includes:

[0039] The conveying device is connected to the desulfurization device at one end and a diversion device connected to each spraying device at the other end. The diversion device is used to transport the desulfurization wastewater to the corresponding spraying device. The conveying device can be a conveying pipeline.

[0040] Furthermore, the target area includes slag storage, ash storage, and fuel coal yard;

[0041] The conveying device also includes a main conveying pipe, and the diversion device includes a first diversion channel corresponding to the slag silo, a second diversion channel corresponding to the ash silo, and a third diversion channel corresponding to the fuel coal yard. The input end of the main conveying pipe is connected to the discharge end of the desulfurization device, and the output end of the main conveying pipe is connected to the first diversion channel, the second diversion channel, and the third diversion channel. The first diversion channel is connected to the spraying device corresponding to the slag silo, the second diversion channel is connected to the spraying device corresponding to the ash silo, and the third diversion channel is connected to the spraying device corresponding to the fuel coal yard. An electric shut-off valve is installed at the inlet of the main conveying pipe.

[0042] It should be noted that the spraying device applied to the third diversion channel is used to spray the coal piles in the fuel coal yard. The wastewater generated after desulfurization is diverted to the ash silo, slag silo and fuel coal yard through the conveying device. The wastewater is treated by dust suppression in the ash silo and slag silo and by spraying the coal piles. During the use of the sprayed coal piles, the components in the wastewater are continuously recycled.

[0043] Furthermore, the system also includes a purging device for purging the conveying device.

[0044] It should be noted that the purging device is a compressed air purging pipeline. One end of the compressed air purging pipeline is connected to the main delivery pipeline. The compressed air source is led out from the outlet pipeline of the desulfurization compressed air storage tank. A shut-off valve is installed on the compressed air storage tank to the wastewater discharge pipeline. The purging device is used to solve the problem of the delivery pipeline freezing in winter.

[0045] In summary, the beneficial effects of the desulfurization wastewater discharge system of the present invention are that it not only solves the problem of desulfurization wastewater discharge and greatly reduces the risk of environmental incidents, but also eliminates the problems of low desulfurization efficiency, high consumption of plant power and limestone powder caused by the non-discharge of desulfurization wastewater, which may lead to serious environmental incidents and shutdowns in severe cases. It further meets the environmental emission requirements of the unit and protects the surrounding environment.

[0046] Example 2

[0047] Referring to Figures 2 to 5, the second embodiment of the present invention provides a specific structure of the desulfurization device, which is otherwise the same as that in Embodiment 1. It can perform the function of oil injection on the bearings of the sealing box 102d and the bearing box 102e through the extrusion component 203, thereby ensuring the stable operation of the stirring shaft 102b.

[0048] Specifically, the desulfurization device includes a main unit 100, which includes a desulfurization tower 101 and a stirring assembly 102 fixed to the side of the desulfurization tower 101.

[0049] The oil injection unit 200 includes a protective box 201, an oil storage component 202 disposed on the protective box 201, an extrusion component 203 for driving the oil storage component 202 to discharge oil, and a locking component 204 for locking the extrusion component 203. The protective box 201 is used to fix the stirring component 102 to the side of the desulfurization tower 101.

[0050] Furthermore, the stirring assembly 102 includes a motor 102a, a stirring shaft 102b connected to the motor 102a, a stirring blade 102c fixedly connected to one end of the stirring shaft 102b, a sealing box 102d connected to the stirring shaft 102b, and a bearing box 102e disposed on the stirring shaft 102b. The stirring shaft 102b is provided with multiple bearings. After the locking assembly 204 releases the limit on the extrusion assembly 203, the extrusion assembly 203 is driven to extrude the oil storage assembly 202 to inject lubricating oil into the sealing box 102d and the bearing box 102e.

[0051] It should be noted that the starting motor 102a drives the stirring shaft 102b to rotate, and the stirring blades 102c stir the slurry in the desulfurization tower 101 to prevent slurry particles from settling. The sealing box 102d is fixedly connected at the connection between the stirring shaft 102b and the desulfurization tower 101. The sealing box 102d is equipped with a bearing, and the bearing box 102e is fixedly connected to the stirring shaft 102b. The bearing box 102e is located inside the protective box 201. The motor 102a is fixedly connected to one side of the protective box 201, and one end of the stirring shaft 102b is fixedly connected to the motor 102a through the bearing.

[0052] Furthermore, the locking assembly 204 includes a mounting ring 204a fixedly connected to the inner wall of the protective box 201, a first fixing tube 204b and a second fixing tube 204c disposed inside the mounting ring 204a, a rotating ring 204d located between the first fixing tube 204b and the second fixing tube 204c, a slot 204e disposed in the first fixing tube 204b and the rotating ring 204d, a lifting rod 204f that moves vertically along the first fixing tube 204b, a locking pin 204g disposed on the lifting rod 204f, a limiting plate 204h fixedly connected to one end of the lifting rod 204f, a pressing rod 204i fixedly connected to the other end of the lifting rod 204f, and a locking pin 204g fixedly connected to the lower end of the pressing rod 204i. The components include a fixed lower pressure block 204j, a first spring 204k connecting the lifting rod 204f and the inner wall of the second fixed tube 204c, two driven members 204l symmetrically arranged on the rotating ring 204d, and a limiting member 204m that blocks the driven members 204l. The mounting ring 204a has a hollow structure inside and two extrusion holes are symmetrically provided on the mounting ring 204a. The rotating ring 204d rotates horizontally along the first fixed tube 204b and the second fixed tube 204c. Rubber material is provided between the contact surfaces of the rotating ring 204d and the first fixed tube 204b and the second fixed tube 204c to increase the friction between the three. That is, the rotating ring 204d only rotates under the driving force of an external force.

[0053] The stirring shaft 102b passes through the mounting ring 204a, the locking post 204g moves along the slot 204e, and the first spring 204k is wound around the lower pressure rod 204i. The cross-sectional dimensions of the locking post 204g are adapted to the slot 204e.

[0054] It should be noted that when the lifting rod 204f is pressed, it first moves vertically upward and downward with the cooperation of the slot 204e and the locking pin 204g. The locking pin 204g enters the slot 204e on the rotating ring 204d from the first fixed pin along the slot 204e. The rotating limit plate 204h drives the lifting rod to rotate. The rotation of the lifting rod, with the cooperation of the locking pin 204g and the slot 204e, drives the rotating ring 204d to rotate in a plane, causing the driven member 204l to disengage from the pressing assembly 203.

[0055] Furthermore, the follower 204l includes a push block 204l-1 that moves horizontally along the rotating ring 204d, a push rod 204l-2 that is fixedly connected to the push block 204l-1, and a second spring 204l-3 that connects the push block 204l-1 and the rotating ring 204d, wherein the highest point of the push block 204l-1 is higher than the plane of the rotating ring 204d;

[0056] The limiting component 204m includes a fixed plate 204m-1 that is fixedly connected to the inner wall of the mounting ring 204a at both ends, a third spring 204m-2 that is fixedly connected to the fixed plate 204m-1 at one end, and a U-shaped lifting plate 204m-3 that is fixedly connected to the other end of the third spring 204m-2. The lifting plate is provided with two openings, and the cross-sectional dimensions of the openings are adapted to the dimensions of the push rod 204l-2 and the extrusion hole.

[0057] It should be noted that when the locking assembly 204 does not lock the pressing assembly 203, the lifting rod 204f is at its highest point, the first spring 204k is not compressed, the locking pin 204g is located at the slot 204e in the first fixed tube 204b, and the opening on the U-shaped lifting plate 204m-3 is directly opposite the pressing hole and the push rod 204l-2. When the pressing assembly 203 is locked, the lifting pin moves vertically downward along the slot 204e, simultaneously driving the lowering rod 204i to move vertically along the second fixed tube 204c. The lowering block 204j presses the U-shaped lifting plate 204m-3, the third spring 204m-2 is compressed, and the U-shaped lifting plate 204m-3 moves vertically along the mounting ring 204a, causing the opening to be misaligned with both the pressing hole and the push rod 204l-2.

[0058] Furthermore, the oil storage assembly 202 is provided with two sets;

[0059] The oil storage assembly 202 includes a mounting box 202a fixedly connected to the outer wall of the mounting ring 204a, an oil storage tank 202b through which a protective box 201 is installed and which protects the mounting box 202a, an oil storage bladder 202c connected to the oil storage tank 202b, an oil outlet pipe 202d connected to the oil storage bladder 202c, a U-shaped moving plate 202e driven by a push rod 204l-2, two first inclined blocks 202f and two connecting plates 202g fixedly connected to the side wall of the U-shaped moving plate 202e, and a connecting plate 202g connecting the connecting plate 202g and the inner wall of the mounting box 202a. The wall has a fourth spring 202h and two moving parts 202i driven by two first inclined blocks 202f. The U-shaped moving plate 202e is set directly opposite the extrusion hole. The push rod 204l-2 pushes the U-shaped moving plate 202e through the extrusion hole. The two moving parts 202i are symmetrically arranged with the center of the extrusion hole as the axis of symmetry. A one-way valve is provided at the connection between the oil outlet pipe 202d and the oil reservoir 202c. The other end of the two oil outlet pipes 202d is connected to the sealing box 102d and the bearing box 102e to realize the oil injection of the bearings of both.

[0060] The movable component 202i includes a fifth spring 202i-1 fixedly connected at one end to the inner wall of the mounting box 202a, a fixed vertical plate 202i-2 fixedly connected at the other end of the fifth spring 202i-1, a movable rod 202i-3 passing through the fixed vertical plate 202i-2, and a second inclined block 202i-4 fixedly connected at one end of the movable rod 202i-3. The fixed vertical plate 202i-2 is fixedly connected to the U-shaped movable plate 202e. The fixed vertical plate 202i-2 is connected to the inner wall of the mounting box 202a through a telescopic rod (not shown in the attached figure). The fifth spring 202i-1 is wound around the telescopic rod.

[0061] It should be noted that the push rod 204l-2 passes through the extrusion hole to push the U-shaped moving plate 202e. The U-shaped moving plate 202e moves horizontally along the mounting box 202a, and the fifth spring 202i-1 is tensioned. The first inclined block 202f moves horizontally to extrude the second inclined block 202i-4. The telescopic rod and the fifth spring 202i-1 are tensioned. The two moving rods 202i-3 move to extrude the oil storage bladder 202c. The oil outlet pipe 202d is used to inject oil into the bearings of the sealing box 102d and the bearing box 102e.

[0062] Furthermore, the extrusion assembly 203 is provided in two sets, wherein the two sets of extrusion assemblies 203 are provided corresponding to the two push blocks 204l-1;

[0063] The extrusion assembly 203 includes an extrusion rod 203a passing through the mounting ring 204a, a mounting bracket 203b fixedly connected to two mounting boxes 202a, a sleeve plate 203c fixedly sleeved on the extrusion rod 203a, a sixth spring 203d connecting the sleeve plate 203c and the mounting bracket 203b, and a third inclined block 203e fixedly connected to the lower end of the extrusion rod 203a.

[0064] It should be noted that when the extrusion assembly 203 is not locked, the lowest point of the third inclined block 203e contacts the push block 204l-1, and the contact point is higher than the plane where the rotating ring 204d is located. When oil injection is achieved, by pressing the two extrusion rods 203a separately or simultaneously, the third inclined block 203e moves vertically to extrude the push block 204l-1, which drives the push rod 204l-2 to move horizontally along the extrusion hole, and drives the U-shaped moving plate 202e to move horizontally.

[0065] Preferably, the present invention locks the two extrusion components 203 by means of locking component 204, reducing the possibility of excessive oil injection caused by accidental contact with extrusion component 203. Furthermore, after the extrusion component 203 is released from locking, the two extrusion rods 203a can be pressed separately or simultaneously as needed to achieve the function of sequentially or simultaneously injecting oil into the sealing box 102d and bearing box 102e. The oil injection method is flexible and improves the practicality of the present invention.

[0066] In use, this invention includes two usage states:

[0067] In the first usage state, the locking assembly 204 achieves double locking of the two extrusion assemblies 203, reducing the possibility of excessive oil injection due to accidental contact with the extrusion assemblies 203. Specifically, pressing the lifting rod 204f simultaneously drives the limiting plate 204h, the lower pressure rod, and the lower pressure block 204j to move vertically downwards. The locking pin 204g enters the slot 204e on the rotating ring 204d from the first fixed pin along the slot 204e. Rotating the limiting plate 204h drives the lifting pin to rotate. The rotation of the lifting pin, in conjunction with the locking pin 204g and the slot 204e, drives the rotating ring 204d to rotate in a plane, causing the driven member 204l to disengage from the extrusion assembly 203. The misalignment of the slot 204e causes the first spring 204k to... Unable to reset, the limiting plate 204h contacts the two extrusion rods 203a, limiting the pressing of the two extrusion rods 203a. Furthermore, during the process of the early lifting column moving vertically downward along the slot 204e, the lower pressure block 204j extrudes the U-shaped lifting plate 204m-3, the third spring 204m-2 is compressed, and the U-shaped lifting plate 204m-3 moves vertically along the mounting ring 204a, causing the opening to be misaligned with the extrusion hole and the push rod 204l-2 at the same time. This prevents the internal structure of the mounting ring 204a from entering the mounting box 202a through the extrusion hole, achieving double locking of the locking component 204 on the two extrusion components 203, and reducing the possibility of excessive oil injection due to accidental contact with the extrusion component 203.

[0068] In the second usage state, depending on actual needs, pressing the two extrusion rods 203a separately or simultaneously can achieve the function of sequentially or simultaneously injecting oil into the sealing box 102d and the bearing box 102e. Specifically, the lifting plate is rotated in the reverse direction so that the slot 204e on the rotating ring 204d and the slot 204e on the first fixed tube 204b are on the same axis. Under the reset action of the first spring 204k, the locking of the limiting plate 204h on the two extrusion components 203 is released. At the same time, the rotating ring 204d resets so that the driven member 204l contacts the extrusion component 203. The U-shaped lifting plate 204m-3 resets so that the opening is aligned with the extrusion hole. At this time, the two rods can be pressed separately or simultaneously as needed. The extrusion rod 203a and the third inclined block 203e move vertically to extrude the pushing block 204l-1, which drives the push rod 204l-2 to move horizontally along the extrusion hole, causing the U-shaped moving plate 202e to move horizontally. The U-shaped moving plate 202e moves horizontally along the mounting box 202a, and the fifth spring 202i-1 is tensioned. The first inclined block 202f moves horizontally to extrude the second inclined block 202i-4, and the telescopic rod and the fifth spring 202i-1 are tensioned. The two moving rods 202i-3 move to extrude the oil storage bladder 202c, realizing the function of oiling the bearings of the sealing box 102d and the bearing box 102e through the unlocked extrusion assembly 203, further ensuring the stable operation of the stirring shaft 102b.

[0069] In summary, the beneficial effects of the desulfurization wastewater discharge system of the present invention are as follows: the locking component 204 locks the two extrusion components 203, reducing the possibility of excessive oil injection caused by accidental contact with the extrusion components 203; furthermore, after the extrusion components 203 are released from locking, the two extrusion rods 203a can be pressed separately or simultaneously as needed to achieve the function of sequentially or simultaneously injecting oil into the sealing box 102d and the bearing box 102e. The oil injection method is flexible, which improves the practicality of the present invention and further ensures the stable operation of the stirring shaft 102b.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
