Description

Technical Field

[0001] This invention relates to the fields of environmental protection and resource utilization and aquaculture environment control technology, specifically to a method for aquaculture air conditioning that combines deodorization and energy recovery. Background Technology

[0002] Livestock farms generate a large amount of odor during production, which requires deodorization through ventilation. After the odor is expelled, fresh air from outside needs to be introduced into the farm. However, the external weather conditions often differ significantly from the temperature and humidity requirements of the farm. In summer, the outside temperature is high, and in winter, the outside temperature is low. Adjusting the fresh air to the temperature and humidity required for biological growth consumes a huge amount of energy, resulting in extremely high operating costs.

[0003] In existing technologies, for high-temperature summer scenarios, farms often use evaporative cooling systems with water curtains. However, this method significantly increases the humidity of fresh air, especially in scenarios like black soldier fly farming where fresh air is needed to remove moisture from wet waste. Water curtain cooling cannot meet dehumidification needs and instead exacerbates the humidity burden in the farming space. For low-temperature winter scenarios, farms often reduce or even eliminate ventilation to prevent heat loss. However, without circulating fresh air as a moisture carrier, dehumidification during the farming process cannot be carried out properly, severely impacting farming efficiency and the biological growth environment.

[0004] Furthermore, existing deodorization scrubbing towers, when treating high concentrations of organic odors, experience rapid accumulation of organic pollutants in the circulating spray water, easily causing scaling and blockage in heat exchangers and heat pump units. Conventional HVAC systems, by adding bactericides to inhibit microbial growth, not only fail to fundamentally solve the problem of organic matter accumulation but also increase operating costs and the risk of secondary pollution. Some deodorization solutions incorporate biological packing materials within the scrubbing tower for gas-phase biodegradation, but this method severely compromises the heat exchange and cooling efficiency of the scrubbing tower, failing to simultaneously meet the dual requirements of deodorization and energy recovery. Summary of the Invention

[0005] To address the shortcomings of existing aquaculture systems, such as difficulty in simultaneously achieving ventilation and deodorization while maintaining energy efficiency in air conditioning, easy scaling and clogging of circulating water, and inability to adapt temperature and humidity control to the needs of aquaculture production, this invention provides a method for aquaculture air conditioning that combines deodorization with energy recovery. This method achieves efficient deodorization and fresh air temperature and humidity regulation while recovering exhaust energy to reduce energy consumption, and ensures long-term stable operation of the system through biological water treatment.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a method for air conditioning in aquaculture that combines deodorization and energy recovery, comprising the following steps:

[0007] (1) Exhaust air washing deodorization and energy transfer: The exhaust air in the breeding workshop, which maintains a constant temperature, is sent into the deodorization washing tower. The exhaust air is sprayed and washed by circulating spray water to remove organic pollutants in the odor. At the same time, the exhaust air and the circulating spray water undergo gas-liquid heat and mass exchange, so that the heat energy or cold energy carried in the exhaust air is transferred to the circulating spray water.

[0008] (2) Energy grade enhancement and fresh air temperature regulation: The circulating spray water carrying energy is introduced into the heat pump unit for heat exchange. The energy grade is enhanced by the refrigerant compression and circulation of the heat pump to produce cold or hot water at the corresponding temperature. The fresh air from the outside is first exchanged with the exhaust air of the breeding workshop through an air-to-air heat exchanger to achieve pre-temperature regulation. Then, the cold or hot water prepared by the heat pump is used to adjust the final temperature of the pre-temperature regulated fresh air so that the temperature and humidity of the fresh air meet the set requirements of the breeding workshop before being sent into the breeding workshop.

[0009] (3) Circulating water biological purification: After heat exchange, the circulating spray water is sent to the biological filter, where aerobic microorganisms degrade organic pollutants in the circulating water and filter out impurities. The purified circulating spray water can directly enter the heat exchanger of the heat pump for operation and then return to the deodorization scrubbing tower to adsorb organic pollutants in the new odor.

[0010] Preferred configuration: Under winter operating conditions, the temperature inside the breeding workshop is constant at 30℃, while the ambient temperature is -10℃. The 30℃ exhaust air from the breeding workshop first enters the air-to-air heat exchanger to preheat the outside fresh air to 10℃, and then precools the exhaust air itself to 20℃ and reaches saturated humidity. The precooled exhaust air enters the deodorization scrubbing tower, exchanges heat with the circulating spray water, and transfers the heat to the circulating spray water. The exhaust air is finally cooled to 10℃ before being discharged. The heat pump extracts heat from the circulating spray water and prepares high-temperature hot water, which is used to further heat the preheated fresh air to 25℃ before being sent into the breeding workshop.

[0011] Preferred configuration: Under summer operating conditions, the deodorizing scrubbing tower also functions as a cooling tower to achieve evaporative heat dissipation, directly utilizing the cooled circulating spray water to initially cool the high-temperature fresh air; a water-circulating air conditioning system is formed through a heat pump to prepare chilled water at a temperature of 20°C to cool and dehumidify the hot and humid fresh air, achieving optimal operating condition matching between cooling capacity efficiency and heat exchange efficiency.

[0012] Preferably, the biofilter is a backwashing biofilter or a continuous filtration activated sand filter, which uses the biofilm on the surface of the packing material to aerobically biodegrade organic pollutants in the circulating water.

[0013] Preferred: The gas-to-gas heat exchanger used for pre-temperature adjustment of fresh air and exhaust air in step (2) is a superconducting heat pipe heat exchanger.

[0014] Preferred options include AI dynamic optimization control steps, which collect aquaculture harvest data and HVAC system power consumption data, and combine them with changes in environmental temperature and humidity. The AI ​​algorithm dynamically calculates and adjusts the temperature and humidity settings and system operating conditions of the aquaculture workshop to achieve optimal economic benefits.

[0015] Preferably, the breeding workshop is a black soldier fly breeding workshop, and the fresh air temperature regulation process simultaneously realizes the dehumidification function to meet the water discharge requirements of the black soldier flies during the process of feeding on wet waste.

[0016] Preferably, the deodorizing scrubbing tower does not contain biological deodorizing packing material. It only adsorbs organic pollutants in the odor through spray water. The degradation of organic pollutants is completed entirely in the aqueous phase of the biological filter. At the same time, the water quality purified by sand filtration ensures the heat exchanger in the heat pump without clogging and also ensures the heat exchange effect of the deodorizing scrubbing tower.

[0017] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages compared with the prior art:

[0018] 1. This invention deeply couples deodorization and washing with energy recovery. It utilizes the gas-liquid heat and mass exchange between the exhaust air and the circulating spray water in the breeding workshop to recover the cold or heat energy in the exhaust air. Then, the energy quality is improved by a heat pump and used for fresh air temperature regulation. Under the premise of ensuring ventilation and deodorization, the energy consumption of breeding air conditioning is greatly reduced, which solves the problem of the contradiction between ventilation and energy saving in traditional breeding.

[0019] 2. This invention adopts a fresh air graded temperature regulation mode. First, the fresh air is pre-temperature regulated through air-to-air heat exchange, and then the final temperature is regulated through a heat pump. This fully recovers the exhaust energy and reduces the load on the heat pump. In winter, it can maintain a constant temperature in the breeding workshop under extremely low ambient temperatures. In summer, it can achieve fresh air cooling and dehumidification, replacing traditional water curtain cooling. It is especially suitable for black soldier fly breeding scenarios that require continuous dehumidification.

[0020] 3. This invention is equipped with a biological filter to biologically purify the circulating spray water. By degrading organic pollutants in the water through aerobic microorganisms, it fundamentally solves the problems of scaling and clogging caused by the accumulation of organic matter in the circulating water. There is no need to add bactericides, the operating cost is low and there is no secondary pollution. At the same time, the degradation of organic matter is transferred from the gas phase to the water phase, avoiding the destruction of the heat exchange effect of the scrubbing tower by the biological packing, and taking into account both deodorization efficiency and energy recovery efficiency.

[0021] 4. This invention can dynamically optimize operating parameters through AI algorithms, automatically match the optimal operating conditions by combining aquaculture revenue and energy consumption data, adapt to the environmental changes of the four seasons and day and night, and further improve the economic benefits of the system; at the same time, superconducting heat pipe heat exchangers can be used to replace conventional gas-to-gas heat exchangers, adapt to the heat exchange needs of different scenarios, and the solution is highly flexible.

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0029] It should be noted that the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used herein are for the purpose of illustration only and do not represent the only embodiment.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field of the present invention; the terms used in the specification of the present invention herein are for the purpose of describing specific embodiments only, and are not intended to limit the present invention; the term "and / or" used herein includes any and all combinations of one or more of the associated listed items.

[0031] The following is combined with the attached draw Figures 1-5 ings and specific embodiments to further describe the present invention in detail.

[0032] This embodiment provides a method for air conditioning in aquaculture that combines deodorization and energy recovery. The core idea is to use the aquaculture space as a constant temperature body, with the high temperature in summer relative to the outside as a cold source and the low temperature in winter relative to the outside as a heat source. The energy discharged during ventilation and deodorization is recovered and used for temperature and humidity regulation of the fresh air. When the temperature difference between the exhaust air and the fresh air is small, the energy quality is improved by a heat pump to ensure heat exchange efficiency. At the same time, a biological water treatment system is provided to ensure stable circulating water quality.

[0033] like Figure 1 As shown, the system upon which this method is based mainly includes a deodorizing scrubbing tower 1, a heat pump chiller 2, a fresh air heat exchanger 3, an aquaculture container 7, an auxiliary container 8, and a matching biological filter water treatment unit; the aquaculture container is equipped with a vibrating screen 4, a material receiving and pre-treatment unit 5, an incubation and fattening cabinet 6, and other aquaculture production equipment, forming an integrated container aquaculture system.

[0034] This method specifically includes three core steps: exhaust air washing and deodorization with energy transfer, energy quality enhancement and fresh air temperature control, and circulating water biological purification. It can also be equipped with AI dynamic optimization control, as detailed below:

[0035] Step 1: Exhaust, Scrubbing, Deodorization, and Energy Transfer

[0036] The exhaust air, maintained at a constant temperature within the aquaculture workshop (aquaculture container 7), is collected and sent to the deodorizing scrubbing tower 1. Inside the tower, circulating spray water washes the exhaust air from top to bottom in a counter-current manner. Organic pollutants in the odorous air are adsorbed and transferred to the water by the spray water, achieving a deodorizing effect. At the same time, the exhaust air and the circulating spray water undergo sufficient gas-liquid heat and mass exchange, and the heat energy (in winter) or cold energy (in summer) carried in the exhaust air is transferred to the circulating spray water, achieving a liquid-phase energy transfer.

[0037] In this step, no biological deodorizing packing is installed in the deodorizing scrubbing tower. Organic matter adsorption and gas-liquid heat exchange are completed only by spraying water. This avoids biological packing from obstructing airflow and reducing heat exchange efficiency, thus ensuring the cooling tower heat exchange effect of the scrubbing tower.

[0038] Step 2: Energy Quality Enhancement and Fresh Air Temperature Adjustment

[0039] Energy-carrying circulating spray water flows out from the bottom of the deodorizing scrubbing tower and enters the evaporator / condenser side of the heat pump chiller / heater unit 2 (heat pump unit) for heat exchange. The heat pump uses a single-stage compressed refrigerant cycle (consisting of a compressor, condenser, throttling mechanism, and evaporator) to boost low-grade energy and produce high-temperature hot water or low-temperature chilled water that meets the requirements for fresh air temperature control.

[0040] The temperature control of the outside fresh air adopts a graded treatment mode:

[0041] First, the fresh air from outside passes through the fresh air heat exchanger 3 (air-to-air heat exchanger) and directly exchanges heat with the high-temperature / low-temperature exhaust air discharged from the breeding workshop to achieve preheating or precooling of the fresh air and initially recover the energy in the exhaust air.

[0042] Subsequently, the pre-temperature-controlled fresh air and the cold / hot water prepared by the heat pump undergo secondary heat exchange through heat exchange coils to complete the final temperature regulation. After the temperature and humidity of the fresh air meet the set requirements of the breeding workshop, it is sent into the breeding workshop.

[0043] Example of winter operating conditions:

[0044] like Figure 3 As shown, the breeding workshop maintains a constant temperature breeding environment of 30℃, while the outside temperature is -10℃.

[0045] The 30℃ hot and humid exhaust air discharged from the breeding workshop first enters the air-to-air heat exchanger to exchange heat with the -10℃ outside fresh air, preheating the fresh air to 10℃, and the exhaust air itself is pre-cooled to 20℃ and reaches 100% saturated humidity.

[0046] The pre-cooled 20°C exhaust air enters the deodorizing scrubbing tower, where it further exchanges heat with the circulating spray water, transferring the remaining heat to the circulating spray water. The exhaust air is finally cooled to 10°C and discharged from the top of the tower.

[0047] The heat pump extracts low-grade heat from the circulating spray water, compresses and boosts it to produce high-temperature hot water; the high-temperature hot water is introduced into the fresh air heat exchange coil, which further heats the preheated fresh air to 25°C and sends it into the breeding workshop to maintain a constant temperature environment of 30°C in the workshop.

[0048] Example of summer operating conditions:

[0049] The external environment is hot and humid, while the breeding workshop maintains a set low temperature and low humidity environment. The deodorizing scrubbing tower also functions as a cooling tower for evaporative heat dissipation. The circulating spray water, after being cooled by evaporation, can directly provide preliminary cooling to the high-temperature fresh air. The cooling capacity efficiency ratio (COP) of this process can reach 50, but the heat exchange temperature difference is relatively small.

[0050] A water-loop air conditioning system is formed by a heat pump to produce chilled water at a temperature of 20°C, which deeply cools and dehumidifies the hot and humid fresh air. At this temperature setting, the heat pump's cooling COP can reach 20. At the same time, with a heat exchange structure with a large air front, sufficient heat exchange area can be guaranteed, forming an optimal operating point between energy efficiency ratio and heat exchange efficiency, replacing traditional water curtain cooling, and achieving both cooling and dehumidification.

[0051] In this step, a superconducting heat pipe heat exchanger can be used as an alternative to the gas-to-gas heat exchanger to further improve the heat exchange efficiency in the pre-heat exchange stage and adapt to the climate conditions of different regions.

[0052] Step 3: Biological purification of circulating water

[0053] The circulating spray water after heat exchange contains a large amount of organic pollutants adsorbed from the odor. Directly entering the heat exchanger or heat pump unit can easily cause scaling, clogging, and corrosion. Therefore, the circulating spray water after heat exchange is sent to a biological filter (wastewater treatment biological filter) for purification.

[0054] The biological filter is filled with biological packing material, and an aerobic biofilm is attached to the surface of the packing material. When circulating water flows through the packing material, organic pollutants in the water are adsorbed by the biofilm and degraded into inorganic substances by aerobic microorganisms. At the same time, the packing material layer can filter out suspended impurities in the water. The purified circulating spray water can be directly entered into the heat exchanger of the heat pump (tube or tank heat exchanger is recommended), and after heat exchange, it flows back to the deodorization scrubbing tower for continued circulating spraying.

[0055] Biological filters can be backwashed biological filters, which regularly backwash and replace the packing layer; or they can be continuous filtration activated sand filters, which have a larger treatment volume and better purification effect, and are suitable for high-load odor treatment scenarios.

[0056] AI dynamic optimization control

[0057] The system is equipped with an MCC control cabinet and various sensors for temperature, humidity, water quality, etc., and can be connected to an AI optimization control system. The AI ​​system collects harvest yield data of farmed organisms and real-time power consumption data of the HVAC system. Combined with the diurnal and seasonal changes in external environmental temperature and humidity, it dynamically calculates and adjusts control parameters such as temperature and humidity setpoints, heat pump operating parameters, and ventilation volume in the aquaculture workshop with the goal of maximizing economic benefits.

[0058] AI algorithms can learn from historical operating data and perform collaborative optimization by combining operating data from multiple sites. They also take into account the impact resistance of biological growth and the time delay effect of system operation to achieve optimal operation under all working conditions, further reducing operating costs and improving the overall benefits of aquaculture.

[0059] Supporting post-breeding processing procedures

[0060] When this method is applied to black soldier fly farming, it can be paired with a complete post-processing technology for the farmed products, such as... Figure 4 , Figure 5 As shown: The insect excrement mixture harvested from breeding is first screened and separated by an insect excrement screening machine. The separated insect skins are sent to a low-temperature air-source dryer by a belt conveyor for drying. The dried insect skins are sent to an oil pressing device to extract insect oil. The insect residue after oil pressing is further separated by a two-phase centrifuge to finally obtain defatted insect powder and insect oil products, realizing the resource utilization of breeding products.

[0061] It should be noted that, for example Figure 4As shown in the figure, this is an operation monitoring interface of the HVAC environmental control system, on which 4 sets of parallel cold and hot water unit modules are deployed, and each set of modules is correspondingly equipped with a cooling pump, a freezing pump, a cooling tower fan, and air inlet and outlet louvers; the top of the interface collects and displays the temperature and humidity parameters of multiple exhaust paths in real time, and the cooling tower fan module is marked with the equipment operation frequency parameter; a system start-stop control module is arranged on the right side of the interface, which integrates control functions such as one-click start for tower closing, cooling / heating switching, one-click start for the main unit, and fault silencing, and is also marked with the main unit start-stop interval protection rule to avoid damage caused by frequent start and stop of the equipment.

[0062] This monitoring system is the operation management and control carrier of the heat pump air conditioning and energy recovery system on which the method of the present invention relies, the 4 sets of cold and hot water units correspond to the heat pump cold and hot water units in the present invention, and the cooling pumps and freezing pumps correspond to the circulating conveying equipment for circulating spray water and air-conditioning cold / hot water.

[0063] Through this system, the exhaust air temperature and humidity working conditions can be monitored in real time, and the cooling and heating operation modes can be switched with one click to adapt to different energy recovery and fresh air temperature regulation requirements in winter and summer; meanwhile, centralized management and control and operation protection of the equipment can be realized, which provides a hardware monitoring basis for the AI dynamic optimization control and automatic working condition adjustment in the present invention, and ensures the stable and efficient operation of the deodorization washing and energy recovery coupling system.

[0064] As shown in Figure 5 the figure, this is a top view of the general layout of the plant for the black soldier fly breeding project. A plurality of functional plants are divided in the plant area, which are respectively provided with B1 and B2 gluttonous stage breeding areas, B3 composting screening and insect powder processing area, and B4 hatching and seedling raising area, while supporting an independent drying functional area and a central control room. The whole plant is connected to an intelligent environmental protection monitoring system, which can realize the whole-process production of black soldier flies from seedling raising, breeding to product post-treatment.

[0065] This plant area is a typical application scenario of the "breeding air conditioning method combining deodorization and energy recovery" of the present invention: the breeding / seedling raising workshops such as B1, B2, and B4 all need to be equipped with the ventilation deodorization and constant temperature environmental control system of the present invention, and the method of the present invention is adopted to realize exhaust air deodorization, exhaust air energy recovery and fresh air temperature and humidity regulation of each breeding workshop, so as to meet the constant temperature and constant humidity and continuous dehumidification requirements of black soldier flies at different growth stages.

[0066] The B3 composting screening and drying area corresponds to the supporting post-treatment process of breeding products of the present invention, and forms a complete black soldier fly breeding production system together with the breeding environmental control system; the intelligent environmental protection monitoring system deployed in the plant area also provides a deployment basis for the centralized management and control of the whole plant environmental control system and AI global optimized operation of the present invention.

[0067] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Anyone skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
