Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a product water acidity stripping device. Background Technology

[0002] Landfill leachate is highly concentrated and difficult to treat. Currently, leachate treatment mainly employs a process combining biochemical treatment, ultrafiltration membrane, nanofiltration membrane, and reverse osmosis membrane to achieve compliant discharge.

[0003] In the membrane treatment section, the biochemical effluent passes through an ultrafiltration system, separating most of the activated sludge from the leachate. The ultrafiltration effluent then enters the nanofiltration clarifying tank before entering the nanofiltration membrane. To reduce the calcium and magnesium ions and carbonate ions in the leachate, which combine to form precipitates and clog the nanofiltration membrane, the pH of the nanofiltration feed water needs to be adjusted to around 5, ensuring they exist in ionic form in the water. The nanofiltration permeate undergoes reverse osmosis to further remove dissolved salts and organic matter with a molecular weight greater than 100, before entering the permeate tank. Liquid alkali is added to the permeate tank to adjust the pH to 7-9 before discharge, meeting emission standards.

[0004] Currently, to reduce the likelihood of nanofiltration membrane clogging due to the formation of precipitates from calcium, magnesium, and carbonate ions in the leachate, the pH of the nanofiltration membrane feed water needs to be adjusted to around 5, as the effluent pH discharge standard is 7-9. This requires adding liquid alkali at the reverse osmosis permeate end to adjust the pH from 5 to 7-9 before discharge. However, if the dosing device becomes clogged or there are quality issues with the reagents, water quality will exceed standards. Furthermore, because the solid-liquid alkali concentration is 40%, it must be prepared as a liquid before addition, which poses a risk of burns to personnel. The reagent dosing equipment is also prone to clogging and requires frequent cleaning; if cleaning is not timely, the effluent quality may fail to meet standards.

[0005] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a water acidity stripping device. Utility Model Content

[0006] The purpose of this invention is to provide a water acidity stripping device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a water production acidity stripping device, comprising a water production tank and a connecting pipe, characterized in that: a fixed base is installed at the bottom of the water production tank, and a transmission pipe is installed on one side of the water production tank, and a blower is connected to one end of the transmission pipe, the connecting pipe is connected to the end of the transmission pipe away from the blower, and a stripping pipe is vertically installed at the end of the connecting pipe away from the transmission pipe.

[0008] Furthermore, the water production tank includes a main tank body, a lid, and fixing components. The lid is installed on the top of the main tank body, and fixing components are installed at equal intervals along the sides of the main tank body.

[0009] Furthermore, the fasteners are arranged vertically from top to bottom and connected to the side surface of the main barrel body in a fixed connection with the main barrel body, and the barrel cover adopts a flange structure to be connected to the main barrel body.

[0010] Furthermore, the fixing base includes a base, a support pile, and a fixing anchor rod. The bottom of the base is connected to the support pile, and one end of the support pile is vertically inserted through the fixing anchor rod.

[0011] Furthermore, the support piles are arranged in a ring array with the base as the center, and the fixed anchor rods are threadedly connected to the inside of one end of the support piles.

[0012] Furthermore, the transmission pipe includes an air supply pipe, an air filter, and a union joint. An air filter is installed at one end of the air supply pipe, and a union joint is installed at the end of the air supply pipe away from the air filter.

[0013] Furthermore, the connecting pipe includes a diversion bend, a threaded fitting, and a quick connector. The threaded fitting is vertically installed at the top end of the diversion bend, and a quick connector is installed at the end of the diversion bend away from the threaded fitting.

[0014] Furthermore, the quick connectors are arranged in a circular array with the diversion bend as the center and six sets are installed. The top of the blow-off pipe is connected to the bottom of the quick connector. The end of the threaded fitting away from the diversion bend is connected to the end of the air filter away from the air supply pipe. The air supply pipe runs vertically through the middle of the inside of the fixing component.

[0015] This invention provides a water acidity stripping device, which has the following beneficial effects:

[0016] 1. This utility model involves installing a transmission pipe on one side of the main tank using a fixing component, with a blower installed at one end of the transmission pipe and multiple stripping pipes connected to the other end via a connecting pipe. These pipes are then introduced into the bottom of the entire product water tank. Using this combined structure, a large amount of airflow is generated under the operation of a blower of appropriate power. This airflow, carried by the transmission and stripping pipes, exits from the bottom of the product water tank, generating numerous bubbles and simultaneously injecting external air into the water. This process strips free carbon dioxide from the water, causing the water's pH value to change accordingly. Reducing the amount of chemicals used while increasing their use has several advantages. First, it effectively reduces the use of chemicals, lowering the cost of water treatment. Second, it reduces the safety hazards to workers caused by chemical preparation, providing them with some protection. Third, it reduces the need for frequent cleaning of equipment that is clogged due to chemical addition, preventing substandard water quality caused by untimely cleaning. This effectively saves on chemical dosage while ensuring stable water quality, reducing equipment maintenance costs, and saving labor.

[0017] 2. This utility model connects the stripping pipe and the transmission pipe via a connecting pipe. A threaded fitting connects the diversion bend to the bottom of the air filter. Due to the characteristics of the diversion bend's structure, the airflow transmitted through the air supply pipe is divided into six groups and evenly distributed from inside the water production tank under the transmission of the stripping pipe. This structure ensures that free carbon dioxide is thoroughly and evenly stripped from the water, guaranteeing the stability and effectiveness of pH improvement. Furthermore, the air filter minimizes the entry of external air into the water, effectively filtering and purifying internal impurities and preventing them from affecting the water treatment quality. The separate use of unions, threaded fittings, and quick couplings allows for flexible and quick assembly and disassembly of the transmission pipe, blower, connecting pipe, and stripping pipe, facilitating maintenance by operators and improving both ease of maintenance and structural flexibility.

[0018] 3. This utility model, by installing a fixed base at the bottom of the water production tank, allows for the use of a fixed anchor bolt threaded into the support pile at the bottom of the base, with the lower end of the fixed anchor bolt fixed to the ground. This provides effective structural stability for the entire device. Simultaneously, the base and support pile provide good structural support and bottom counterweight for the water production tank, ensuring its structural stability. Furthermore, the main tank body is connected to the cover via a flange structure, allowing for a degree of structural flexibility in disassembly and facilitating internal structural maintenance. It also facilitates the disassembly and maintenance of the connecting pipes and blow-off pipes, providing convenient assistance. Attached Figure Description

Detailed Implementation

[0024] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0025] like Figures 1 to 4As shown, a water production acidity stripping device includes a water production tank 1 and a connecting pipe 5. A fixed base 2 is installed at the bottom of the water production tank 1, and a transmission pipe 3 is installed on one side of the water production tank 1. A blower 4 is connected to one end of the transmission pipe 3. The connecting pipe 5 is connected to the end of the transmission pipe 3 away from the blower 4, and a stripping pipe 6 is vertically installed at the end of the connecting pipe 5 away from the transmission pipe 3. When the blower 4 operates with appropriate power, a large amount of airflow is generated. With the transmission pipe 3 and the stripping pipe 6, the airflow is output from the bottom of the water production tank 1, generating a large number of bubbles. At the same time, external air is injected into the water body, thereby stripping free carbon dioxide from the water, causing the pH value of the water body to rise as the free carbon dioxide in the water decreases.

[0026] like Figures 1 to 4 As shown, the water production tank 1 includes a main tank body 101, a cover 102, and fixing components 103. The cover 102 is installed on the top of the main tank body 101, and fixing components 103 are installed at equal intervals along the sides of the main tank body 101. The fixing components 103 are vertically arranged from top to bottom and connected to the side surface of the main tank body 101, forming a fixed connection with the main tank body 101. The cover 102 is connected to the main tank body 101 using a flange structure. The fixing base 2 includes a base 201, a support pile 202, and a fixing anchor 203. The support pile 202 is connected to the bottom of the base 201, and the support... One end of the pile 202 is vertically penetrated by a fixed anchor rod 203. The support piles 202 are arranged in a ring array with the base 201 as the center. The fixed anchor rod 203 is threaded into the inside of one end of the support pile 202. The fixed anchor rod 203 can be threaded into the support pile 202 at the bottom of the base 201 and the lower end of the fixed anchor rod 203 can be fixed to the ground. This can provide effective structural stability for the entire device. At the same time, the base 201 and the support pile 202 can also provide good structural support and bottom counterweight for the water production tank 1.

[0027] like Figures 1 to 4As shown, the transmission pipe 3 includes an air supply pipe 301, an air filter 302, and a union connector 303. An air filter 302 is installed at one end of the air supply pipe 301, and a union connector 303 is installed at the end of the air supply pipe 301 furthest from the air filter 302. The connecting pipe 5 includes a diversion bend 501, a threaded fitting 502, and a quick connector 503. The threaded fitting 502 is vertically installed at the top of the diversion bend 501, and a quick connector 503 is installed at the end of the diversion bend 501 furthest from the threaded fitting 502. Six sets of quick connectors 503 are arranged in a circular array around the diversion bend 501, and the top of the blow-off pipe 6... The end of the quick connector 503 is connected to the bottom of the quick connector 503. The end of the threaded pipe 502 away from the diversion bend 501 is connected to the end of the air filter 302 away from the air supply pipe 301. The air supply pipe 301 is vertically inserted through the middle of the inside of the fixing member 103. The blow-off pipe 6 and the transmission pipe 3 are structurally connected by the connecting pipe 5. The diversion bend 501 is connected to the bottom of the air filter 302 by the threaded pipe 502. At the same time, due to the characteristics of the diversion bend 501 itself, the airflow transmitted by the air supply pipe 301 is divided into six groups and output equally from the inside of the water production tank 1 under the delivery of the blow-off pipe 6.

[0028] In summary, as Figures 1 to 4 As shown, when using the product water acidity stripping device, the product water tank 1 is first erected on the ground using the base 201 connected to the support pile 202. Then, six sets of fixed anchor rods 203 are threaded into the interior of the six sets of support piles 202, and the bottom of the fixed anchor rods 203 is nailed into the ground to structurally fix the entire product water tank 1.

[0029] Then, the output end of the blower 4 can be connected to the lower end of the air supply pipe 301 installed on the side of the main barrel 101 using the union 303. Next, the diversion bend 501 can be installed at the bottom output end of the air filter 302 using the threaded pipe fitting 502. Then, the six quick connectors 503 at the bottom of the diversion bend 501 can be connected to the six sets of blow-off pipes 6 in sequence, and the end of the blow-off pipe 6 can be guided to the bottom inside the main barrel 101.

[0030] Then, under the operation of blower 4, the required airflow is generated and enters the interior of stripping pipe 6 through transmission pipe 3 and connecting pipe 5. During this period, air filter 302 filters and purifies the airflow entering the stripping pipe 6 to avoid unnecessary impact on the water body to be treated. As the purified airflow is injected into the interior of the water body and generates a large number of bubbles, the water body is disturbed. By injecting external air into the water body, free carbon dioxide in the water is stripped away, causing the pH value of the water body to rise as the free carbon dioxide in the water decreases, thereby meeting the processing needs of subsequent water filtration.

Many modifications and variations will be apparent to those skilled in the art.
