Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of air purification, and in particular relates to a microalgae matrix type air purification cabin. BACKGROUND

[0002] With the industrialization process and urban development, indoor and outdoor air pollution problems are becoming increasingly serious, and the types of pollutants are becoming diversified and complex. For example, industrial waste gas contains nitrogen oxides and heavy metal particles, decoration pollutants contain volatile organic compounds such as formaldehyde, and waste disposal sites are accompanied by odor gases such as hydrogen sulfide. Therefore, in order to reduce pollution to the environment, it needs to be purified.

[0003] Traditional air purification technologies, such as activated carbon adsorption, photocatalytic oxidation, and chemical washing, can achieve certain purification effects, but generally have problems such as insufficient targeting, high operating cost, and easy secondary pollution. For example, activated carbon has poor selectivity for different pollutants and needs to be replaced frequently, photocatalytic technology has limited treatment efficiency for low-concentration pollutants, and chemical washing method needs to continuously add reagents and may leave harmful substances. In contrast, microalgae, as an efficient carbon dioxide fixer, can convert carbon dioxide into biomass through photosynthesis, not only absorbing carbon dioxide in industrial waste gas to alleviate the greenhouse effect, but also removing nitrogen oxides and other pollutants in waste gas. The active substances produced in its metabolic process also have a certain enrichment effect on heavy metal particles. At the same time, the microalgae cultivation process does not require complex equipment and a large amount of chemical reagents, and only relies on sunlight, moisture and nutrients to grow and reproduce, which is low in cost and has no secondary pollution. However, the existing technology is difficult to simultaneously treat multiple pollutants with a single purification module when dealing with complex pollution scenarios, and multiple devices are needed, which not only occupies a large space, but also cannot be dynamically adjusted according to the pollution type. In addition, traditional purification methods rely on physical adsorption or chemical reagents, which have problems such as adsorption saturation and reagent consumption, high operating cost and easy secondary pollution. In addition, the detection and purification process of pollutants lacks precise linkage, often resulting in over-purification or insufficient purification, leading to energy waste and low purification efficiency. In view of this, the present application is proposed. SUMMARY

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments will be described clearly and completely below in combination with the drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application, but not to limit the scope of the present application.

[0019] Embodiment 1: refer to Figure 1 , Figure 2 , Figure 4 , Figure 6, microalgae matrix air purification cabin, comprising an air suction pump 4 and a plurality of purification cabin bodies 2, wherein two adjacent purification cabin bodies 2 are connected by fixed bolts, different types of microalgae are cultured in each purification cabin body 2, and different types of microalgae purify different harmful substances; a gas delivery pipe 401 is connected to the output end of the air suction pump 4, wherein the end of the gas delivery pipe 401 away from the air suction pump 4 is connected to the air inlet end of each purification cabin body 2 through a hollow rod 403; a plurality of air sensors 402 for detecting different harmful substances in the air are equidistantly arranged in the gas delivery pipe 401.

[0020] When in use, four purification cabin bodies 2 are taken as an example, Chlorella, Scenedesmus, Diatom and Spirulina are cultured in the four purification cabin bodies 2 from bottom to top, Chlorella can purify carbon dioxide and nitrogen oxides in the air, Scenedesmus has a purifying effect on volatile organic compounds such as formaldehyde, Diatom can adsorb heavy metal particles and part of harmful gases in the air, and Spirulina can remove hydrogen sulfide and other odor gases and part of harmful components; When purifying the air, the air suction pump 4 is started to extract the air to be purified, the air flows through the gas delivery pipe 401, and the air sensors 402 in the pipe detect and identify the types (such as carbon dioxide / nitrogen oxides, formaldehyde, heavy metal associated pollutants, hydrogen sulfide, etc.) and concentrations of the pollutants in the air at the same time, then, according to the detection results of the sensors, the system automatically judges the purification cabin body 2 to be called, if high-concentration carbon dioxide and nitrogen oxides are detected, the hollow rod 403 is controlled to connect the Chlorella cabin body (cabin body a), if volatile organic compounds such as formaldehyde are detected, the hollow rod 403 is controlled to connect the Scenedesmus cabin body (cabin body b), if heavy metal particles and specific harmful gases are detected, the hollow rod 403 is controlled to connect the Diatom cabin body (cabin body c), and if hydrogen sulfide and other odor gases are detected, the hollow rod 403 is controlled to connect the Spirulina cabin body (cabin body d), after the air enters the corresponding purification cabin body 2, the air is purified by the physiological characteristics of the microalgae: Chlorella cabin body: Chlorella absorbs carbon dioxide through photosynthesis, and the enzyme system produced during metabolism degrades nitrogen oxides (such as converting NO x into harmless nitrogen-containing compounds); Scenedesmus cabin body: Scenedesmus starts the metabolic pathway to decompose formaldehyde into carbon dioxide and water (such as first oxidizing formaldehyde into formic acid, and then converting it through the Calvin cycle); Diatom cabin body: the siliceous micropores of the cell wall of Diatom adsorb heavy metal particles (such as PM2.5 wrapped lead and mercury, etc.), and the enzymes in the cells degrade harmful gases (such as gradually metabolizing benzene series); Spirulina cabin: Spirulina uses photosynthetic sulfur metabolism to convert hydrogen sulfide into elemental sulfur or sulfate to avoid odor and toxicity, and simultaneously degrades other associated harmful components. Microalgae rely on photosynthesis and biochemical metabolism to achieve purification without the need for additional chemical reagents, reducing the risk of secondary pollution. The air purified by microalgae is then discharged from the exhaust end of the purification cabin 2. The purification cabin is connected by fixed bolts, allowing the air purification cabin to flexibly add or remove purification cabins 2 according to the type and degree of pollution (e.g., adding cabins when pollution is complex). This facilitates maintenance and expansion. The air sensor 402 accurately detects the air and directs it into the corresponding microalgae cabin, improving purification specificity and efficiency. Multiple microalgae work together to purify a wide range of harmful substances, expanding the purification range and improving the purification capacity of the air purification cabin.

[0021] Example 2: Refer to Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 The microalgae matrix air purification cabin is basically the same as example 1, and further includes a filter tank 1. The filter tank 1 stores water for preliminary filtration of air. The air outlet end of the air supply pipe one 401 is inserted into the filter tank 1. The hollow rod 403 is connected to the filter tank 1. The upper end of the filter tank 1 is connected to the inside of the hollow rod 403 through the air supply pipe two 404.

[0022] The air supply pump 701 and the pressure regulating air bag 7 are also included. The pressure regulating air bag 7 is arranged in the filter tank 1 and is in communication with one end of the hollow rod 403 that penetrates the filter tank 1. The air supply pump 701 is arranged on one side of the filter tank 1. The air supply pump 701 is in communication with the pressure regulating air bag 7 through the booster pipe 702. One end of the hollow rod 403 that penetrates the upper end of the filter tank 1 is provided with an electromagnetic valve.

[0023] The purification cabin 2 includes a lower cabin 201 and an upper cabin 202. The upper cabin 202 is inserted into the lower cabin 201. The upper end of the lower cabin 201 and the upper cabin 202 is provided with an exhaust hole 203. The purification cabin 2 is provided with an inflatable air bag 301. One end of the inflatable air bag 301 is fixedly connected to the inner wall of the lower cabin 201, and the other end is fixedly connected to the inner wall of the upper cabin 202. When the inflatable air bag 301 expands, it can push the upper cabin 202 upwards, increasing the internal volume of the purification cabin 2. At the same time, the expansion of the inflatable air bag 301 also raises the liquid level of the microalgae cultured in the purification cabin 2, thereby extending the flow path of the air in the purification cabin 2.

[0024] The lower cabin body 201 is provided with an air inlet pipe 3 in communication with the bottom of the inflatable air bag 301, wherein when the hollow rod 403 rises or falls, the air outlet end of the hollow rod 403 is in communication with the air inlet end of the air inlet pipe 3, and a plurality of air nozzles 302 are fixedly and circumferentially connected to the outer wall of the lower end of the inflatable air bag 301.

[0025] When purifying air, the air suction pump 4 is started to extract the air to be purified. The air first flows into the air conveying pipe 401, and then enters the water in the filter tank 1. The water uses its own physical properties to intercept large-particle dust and dissolve part of the easily soluble harmful gas (such as sulfur dioxide, etc.), thereby completing the preliminary filtration. The air after preliminary filtration enters the hollow rod 403 through the air conveying pipe 2 404 by means of the air pressure difference, thereby preparing for subsequent purification; The air conveying pump 701 is started synchronously. The air conveying pump 701 charges the pressure regulating air bag 7 through the booster pipe 702. Due to the inflation volume expansion, the buoyancy of the pressure regulating air bag 7 increases. Under the action of the buoyancy, the hollow rod 403 is pushed upward. The air conveying pump 701 accurately controls the inflation amount of the pressure regulating air bag 7 according to the results of the air pollutant type, concentration, etc. detected by the air sensor 402, so that the air outlet end of the hollow rod 403 rises to an appropriate height and accurately coincides with the air inlet end of the corresponding air inlet pipe 3 of the purification cabin body 2, thereby establishing a stable air path connection. At this time, the gas in the hollow rod 403 is conveyed to the inflatable air bag 301 through the air inlet pipe 3, and then is filled into the purification cabin body 2 through the air nozzles 302. Since the conveying amount of the gas into the inflatable air bag 301 is greater than the ejection amount of the air nozzles 302, the internal pressure of the inflatable air bag 301 gradually increases, and then the inflatable air bag 301 expands and stretches. The inflated inflatable air bag 301 pushes the upper cabin body 202 upward, increases the internal volume of the purification cabin body 2, and at the same time, pushes the cabin microalgae liquid level upward, prolongs the flow path of the air in the purification cabin body 2, increases the contact area and time of the air and the microalgae, and makes the air and the microalgae fully contact, thereby improving the purification effect. The microalgae purify the air by using its own physiological characteristics (such as the photosynthetic carbon fixation and degradation of nitrogen oxides of chlorella), and the purified air is discharged from the purification cabin body 2 through the exhaust hole 203. After the purification is completed, the air suction pump 4 is closed, and the electromagnetic valve on the hollow rod 403 is opened. At this time, the pressure regulating air bag 7 fills the pre-stored microalgae growth auxiliary gas such as mixed gas rich in CO2, O2 and trace nutrients into the inflatable air bag 301 through the hollow rod 403 and the air inlet pipe 3, and then uniformly sprays it into the purification cabin body 2 through the air nozzles 302. This solves the problem that the activity of the microalgae decreases due to insufficient nutrition and metabolic accumulation after purification by traditional equipment, thereby reducing the frequency of replacing the microalgae and the maintenance cost. To prevent the pressure regulating air bag 7 inside the air pressure drop, the buoyancy drop, causing the hollow rod 403 gas outlet end and the air inlet pipe 3 air inlet end separation, can start to air pump 701 through the booster pipe 702 to the pressure regulating air bag 7 inside the air, make the pressure regulating air bag 7 inside the air pressure remains constant, after the injection of the appropriate amount of auxiliary microalgae growth gas into the purification cabin 2, close the air pump 701 can, at this time, the pressure regulating air bag 7 continues to exhaust, internal pressure decreases, the hollow rod 403 under the action of gravity slowly down reset, at the same time, the inflatable air bag 301 continues to exhaust, internal pressure drop, the upper cabin 202 under the action of gravity slowly down reset, restore the initial cabin volume.

[0026] Air sensor 402 with air pump 701 control, can let the hollow rod 403 precision docking corresponding purification cabin 2, different purification cabin 2 can cultivate the microalgae suitable for the pollutants, such as for nitrogen oxides with chlorella cabin, based on the physiological characteristics of microalgae directional purification, solve the traditional purification one size fits all problem, improve the purification of complex pollutants targeted; The volume increase and microalgae liquid level rise caused by the inflation of the inflatable air bag 301, the air flow path is extended, the gas-algae contact time and area are increased, which can make the pollutants be more fully captured and degraded by microalgae. For example, the residence time of formaldehyde in the cabin is extended, and the sticchococcus can more completely decompose it into carbon dioxide and water, greatly improving the purification efficiency and making the purified air cleaner. Since the volume of the purification cabin 2 is variable, when the pollution load changes (such as when the equipment of a factory is started or stopped, causing the concentration of exhaust gas to fluctuate), the volume can be adjusted to ensure the purification effect, allowing the system to adapt to different working conditions without the need to frequently replace equipment or adjust operating parameters, thereby improving the flexibility and applicability of the system.

[0027] It should be noted that the air inlet pipe 2 404, the hollow rod 403, and the air inlet pipe 3 are all provided with one-way valves. The air inlet pipe 2 404 is a stretchable and contractible hose, so the air inlet pipe 2 404 does not interfere with the lifting and lowering of the hollow rod 403.

[0028] Embodiment 3: Refer to Figure 5 The microalgae matrix type air purification cabin is basically the same as that of embodiment 1, and further, the injection end of the air injection nozzle 302 is inclined and arranged towards the inner wall of the lower cabin 201. When the air injection nozzle 302 injects the air to be filtered into the purification cabin 2, the air flow can form a spiral flow trajectory along the inner wall of the lower cabin 201, enhancing the contact between the air and the microalgae in the cabin.

[0029] In the process of purifying the air, the air to be purified enters the inflatable air bag 301 through the hollow rod 403 and the air inlet pipe 3. Since the input amount of gas is greater than the discharge amount of the air injection nozzle 302, the inflatable air bag 301 expands to push the upper cabin 202 upwards, increasing the volume of the purification cabin 2, and at the same time, the liquid level of the microalgae rises. Air is sprayed from the air nozzle 302 at a high speed at an inclined angle, when it contacts the inner wall of the lower cabin body 201, it is constrained by the inner wall and affected by the inertia of the gas, the airflow obtains a tangential component, and begins to move spirally along the inner wall. As the airflow continues to rise, the spiral trajectory gradually converges to the center of the cabin, and finally exits from the top exhaust hole 203. During the rising process of the spiral airflow, it continues to exchange materials with the microalgae. For example, when processing air containing formaldehyde, the spiral airflow in the Chlorella cabin repeatedly passes through the dense area of microalgae, further prolongs the contact time, and ensures that the formaldehyde is fully decomposed into carbon dioxide and water. The air purified by the microalgae rises along the spiral trajectory to the top and is orderly discharged from the cabin through the exhaust hole 203, avoiding airflow short circuiting or local insufficient purification, and further improving the purification effect. Embodiment 4: with reference to Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 The microalgae matrix air purification cabin is basically the same as that in Embodiment 1, and further, a sliding groove 501 in the form of a ring is arranged on the air inlet pipe 3, a sealing sleeve 502 is sleeved on the air inlet pipe 3, a sliding block 503 is fixedly connected to the inner wall of the sealing sleeve 502, the sliding block 503 is slidingly connected in the sliding groove 501, a spring one 504 is arranged in the sliding groove 501, one end of the spring one 504 is fixedly connected with the sliding block 503, and the other end is fixedly connected with the inner wall of the sliding groove 501, an adsorption block 505 is arranged on one end of the sealing sleeve 502, a sealing gasket 506 is arranged on the inner wall of the sealing sleeve 502, and an electromagnet 5 cooperating with the adsorption block 505 is fixedly installed on the air outlet end of the hollow rod 403.

[0030] A fixed ring 6 is fixedly connected in the hollow rod 403, a sliding rod 604 is slidingly connected to the fixed ring 6, a leakage disc 601 is fixedly connected to the upper end of the sliding rod 604, and a limiting block is fixedly connected to the lower end of the sliding rod 604. A conductive ring one 602 is inlaid on the leakage disc 601, and a conductive ring two 603 is fixedly installed in the hollow rod 403. The conductive ring one 602 and the conductive ring two 603 are used to control the on-off of the electromagnet 5. A spring two 605 is sleeved on the sliding rod 604, one end of the spring two 605 is fixedly connected with the lower end face of the fixed ring 6, and the other end is fixedly connected with the upper end face of the limiting block.

[0031] The air pump 4 starts to extract the air to be purified, the air enters the hollow rod 403 through the air conveying pipe one 401, and the impact force of the high-speed flowing gas acts on the leakage disc 601. Under the impact force of the gas, the leakage disc 601 drives the sliding rod 604 to move upward by overcoming the resistance of the spring two 605, and compresses the spring two 605. At the same time, the conductive ring one 602 on the leakage disc 601 moves upward synchronously. When the conductive ring one 602 contacts the conductive ring two 603, a closed circuit is formed, and the electromagnet 5 is energized; The electromagnet 5 generates magnetic attraction force after being powered on, and the adsorption block 505 on the sealing sleeve 502 is adsorbed. Under the action of the magnetic force, the sealing sleeve 502 is driven to move towards the electromagnet 5 to compress the spring 504, until the electromagnet 5 contacts the adsorption block 505. At this time, the sealing sleeve 502 is tightly sleeved between the hollow rod 403 and the air inlet pipe 3, the sealing gasket 506 is deformed under pressure, fills the joint gap, and realizes efficient sealing of the air path. Air enters the purification cabin 2 through the sealed channel for purification treatment, avoiding the leakage of un-purified air through the gap between the hollow rod 403 and the air inlet pipe 3, causing environmental pollution. After the air purification is completed, the air suction pump 4 stops working, and there is no air passing through the hollow rod 403 to act on the air leakage disc 601. The elastic potential energy of the compressed spring 605 is released to push the sliding rod 604 and the air leakage disc 601 to reset downward, the conductive ring 602 is separated from the conductive ring 603, the electromagnet 5 loses magnetism after being powered off, the spring 504 restores deformation to drive the sealing sleeve 502 to return to the original position, the air path connection is disconnected, and the system returns to the initial standby state, waiting for the next purification task.

[0032] Example 5: Refer to Figure 3 Figure 5 The microalgae matrix type air purification cabin is basically the same as that in example 1, and further, the outer wall of the lower end of the upper cabin body 202 is provided with a sealing ring 204, which is attached to the inner wall of the lower cabin body 201. When the upper cabin body 202 moves upward due to the expansion of the air bag 301, the sealing ring 204 continuously attaches to the inner wall of the lower cabin body 201 to fill the gap between the upper cabin body 202 and the lower cabin body 201, form a sealing surface, and prevent the internal gas from leaking out, so that air can only be discharged through the predetermined path (such as being in contact with the microalgae in the purification cabin 2 and then being discharged from the air outlet 203), improve the purification effect, and avoid the leakage of un-purified air through the gap between the upper cabin body 202 and the lower cabin body 201, causing environmental pollution.

[0033] The inner wall of the bottom of the filter tank 1 is conical, and the bottom of the filter tank 1 is fixedly connected with a liquid delivery pipe 101, and the liquid delivery pipe 101 is provided with a valve switch. After the water in the filter tank 1 preliminarily filters the air, the filtered pollutants (such as dust deposition and accumulated harmful substances) are left in the water. When it is necessary to change the water or clean it, the valve switch is opened, and the water and the deposited pollutants are gathered to the liquid delivery pipe 101 through the conical bottom to be discharged, so as to facilitate the replacement of new water and ensure the preliminary filtering effect. At the same time, the liquid delivery pipe 101 also facilitates the flushing of the inside of the filter tank 1. The conical design facilitates the deposition and concentration of pollutants, making the filter tank 1 convenient to operate, ensuring the long-term stability of the water filtering function, and avoiding the accumulation of pollutants affecting the filtering effect. ​
