Description

The invention relates to the field of transportation of living hydrobionts over long distances in containers equipped with devices for treating their aquatic habitat.

Known installation for the maintenance and transportation of live fish [AS No. 522838, publ. 07/30/1976]. Installation includes: capacity for fish; aeration device; a device for thermal treatment of the aquatic environment, equipped with a thermal relay; a device for cleaning the aquatic environment from suspensions, which is a sludge separator; closed circulation circuit with pump; a tank with a supply of clean water; a pipeline connected to the circulation circuit with a valve for supplying outboard water; an ozonizer included in the circulation circuit between the aerating device and the tank. The fish tank is equipped with a grate installed above the bottom to form a cavity for collecting contaminants, and perforated tubes for supplying and draining water. A pipeline with an ejector for cleaning is mounted at the bottom of the tank. The upper wall of the container is made inclined and has a loading neck and a branch pipe for removing air. The water level in the tank is regulated by a valve. Inside the sludge separator there are perforated guide shields that change the direction of movement of water moving at a low speed, as a result of which suspended particles are retained and deposited on the bottom of the sludge separator. The aerating device is a water-air ejector operating with the help of a circulation circuit. The ozonizer provides water disinfection and partial enrichment with oxygen due to its saturation with O ₃ ozone and its subsequent decomposition into O ₂ and O. A refrigeration unit is used to create a given temperature regime of water. Installation for keeping and transporting live fish works as follows. Through the neck, the container is filled with water using any ship's means or a circulation pump, for which the valves are closed, and water enters from the side through another valve. Upon reaching a certain water level in the tank, live fish is loaded into it, the vital activity of which is ensured by the operation of the installation either along an open circulation circuit, on a channel, while the vessel is at sea or in a bay with clean sea water, or along a closed circulation circuit when the vessel is moving in dirty sea water or fresh water. After the installation is started, the following are switched on: a sludge separator, for which one valve is opened and another valve is closed; an aerating device, for which one valve opens and another valve closes; drinking water ozonator - by opening one valve and closing another valve; device for thermal water treatment - by closing the next valve; the refrigeration unit turns on. Then the solenoid valve opens, and the operation of the refrigeration unit is controlled by a thermal relay. Blowing off the sludge separator from sedimentation of sludge and mucus is carried out periodically, for which one valve at its outlet is closed and another valve is opened, the sludge is removed overboard or into any container. After cleaning, the sludge separator is put back into operation. In case of leakage or evaporation of sea water from the tank, it is replenished from the tank by opening the valve. The water from the cistern is also used for the transportation and storage of live fish in stores.

The disadvantages of the known installation for the maintenance and transportation of live fish are: stationary use only in maritime transport; there is a risk of injury to live fish when it moves in the water against perforated pipe outlets in water flows and the bottom grate of the tank; high labor intensity of the installation control by manual valves due to the lack of appropriate automation tools, therefore, it is necessary to perform a large amount of manual operations for closing and opening valves; low degree of water purification in the tank, which worsens the conditions for the existence of live crustaceans and molluscs during transportation; insufficient funds to provide a life-supporting aquatic environment for live aquatic animals in the tank; when transporting fish over long distances, mixtures of metabolic products accumulate in containers with fish, which oxidize, decompose and create conditions that are unacceptable for the normal life of fish, which leads to a decrease in the life of the transported fish.

Also known refrigerated container for the transport of live fish, equipped with means of wet and dry filtration of the aquatic habitat of fish [patent KR 20100010476, publ. 03/01/2015]. The container contains a cargo room for cargo placement, on the front side of the cargo room there is an entrance door, and on the rear side there is a drive unit that controls the vital activity of live fish in tanks, powered by a trailer vehicle or a vessel. The temperature of live fish, measured with a thermometer, and the signals from sensors are the basis for managing the life cycle of live fish. The drive unit also contains a stationary refrigeration unit, a condenser including a compressor, a heat dissipation fan, an expansion valve and an evaporator. The refrigeration unit is designed to regulate the internal temperature of the container room and the aquatic habitat of live fish. The internal temperature of the cargo space of the container can be regulated from +26°C to -28°C, while the temperature of the aquatic habitat of live fish in the tanks is maintained at approximately +5°C. Four stationary water tanks are installed inside the cargo space to accommodate live fish, between which filtration tanks are installed, used for wet filtration of the aquatic habitat of live fish. Tanks with water for placing live fish and filter tanks for wet water filtration when transporting live fish are closed with lids from above. The filtration tank for dry filtration of the aquatic fish habitat contains a body installed on the outer side of the upper part of the tanks with live fish along the length of the cargo space. A filter material is placed in the body of the filtration tank, and a dry filtration means is installed on top of the body, consisting of a pipe for injecting filtered water into tanks with live fish. The live fish filtered water injection pipe is connected to a circulation pipe passing through the live fish tanks, where water is supplied by a circulation pump. The body of the filtration tank has a drain hole for introducing purified water that has passed through the filter medium into the inside of the tank to live fish. The filter medium contains a porous pellet filter, consisting of pellet granules and located in the inner lower part of the filter tank body. A porous fibrous filter in the form of a sponge is laid on top of the pellet filter. The fiber filter and the pellet filter are impregnated with microorganisms for additional water purification of live fish. The pipe for supplying air to the tanks is made with holes and is installed on the upper side of the filter material together with a pipe for injecting water into the tanks with live fish. In turn, the air supply pipe is connected to the discharge side with a blower located in the drive unit, and the water injection pipe is connected to the circulation pipe passing through the circulation pump and pressure pump to supply water to the live fish tanks.

The disadvantages of the known refrigerated container for the transportation of live fish are: the lack of pre-washing of live marine animals before being placed in tanks, which increases the likelihood of infection and disease during transportation; lack of trays for the rational distribution of live fish over the volume of the tanks, which reduces the level of its safety, since there is a risk of injury to live fish when it moves in the water against perforated partitions and protruding plates in the water flows in the tanks; a complex control scheme for filter tanks for wet and dry filtration of the aquatic habitat of live fish due to the lack of appropriate automation tools; the impossibility of using the container for a mixed type of transportation over a long distance and storage without connecting to external power supplies; the inability to completely replace the water in the tanks, which may be required when transporting a container with live fish.

The closest in technical essence is a system and method for transporting live aquatic animals between shipping points [patent US 2007022966, publ. February 1, 2007]. The system for transporting live aquatic animals between shipping points comprises: water-filled tanks for keeping live animals in a life-sustaining aquatic environment during transport; a marine refrigerated container provided with means for cooling, aerating and circulating water in said tanks during transport; a docking station located at a shipping point, the docking station comprising docking means for receiving an offshore refrigerated container containing the tanks; and means for providing a life-supporting aquatic environment for living aquatic animals in tanks placed in a refrigerated sea container while the refrigerated sea container is attached to the docking station. The means for providing a life-supporting aquatic environment for living aquatic animals provided in the docking station comprise a circulation means for circulating water between the tanks in the refrigerated sea container and the docking station, a filtering means for purifying water circulating between the tanks in the refrigerated sea container and the docking station. The means for providing a life-supporting aquatic environment for living aquatic animals provided in the docking station comprise cooling means for cooling the water circulating between the tanks in the marine refrigerated container and the docking station. The means for providing a life-supporting aquatic environment for living aquatic animals provided in the docking station further comprise a means for aerating the water circulating between the tanks in the marine refrigerated container and the docking station. The marine refrigerated container includes a first water circulation pipeline between each of the tanks and the docking station, while the marine refrigerated container is attached to the docking station. The marine refrigerated container comprises a first conduit that directs raw water from the connection means provided between the docking station and the marine refrigerated container to and from the tanks within the marine refrigerated container. The marine refrigerated container includes a second pipeline for distributing air within said marine refrigerated container to the tanks in order to aerate the water inside the tanks and create an airlift effect to circulate water in the tanks during transport. The marine refrigerated container contains an air circulation means in the form of a compressor, which is separated from the means for cooling water in the tanks and communicates with the second pipeline. Each tank contains an additional tank, equipped with its own individual set of filters for partial purification of the water contained in the tanks during transportation, while in the tanks the filters are combined into a single unit. The water contained in each reservoir is circulated through said filters by an airlift effect caused by the air passing through said reservoir. The filter set contains a mechanical filter and two biological filters. The cooler for cooling water in tanks during transportation in a sea refrigerated container contains a cooling unit for cooling the air passing through the cooling block, an air circulation means for circulating the air contained in the refrigerated sea container and also passing through the cooling block. The method of transporting live aquatic animals between shipping points includes the following steps: placing live aquatic animals in water tanks; placement of tanks in a refrigerated sea container equipped with means for cooling, aerating and circulating water in the tanks during transportation; extracting tanks with live aquatic animals from the marine refrigerated container and attaching them to the docking station at the place of shipment, for which the docking station is equipped with docking means for connecting tanks with live aquatic animals; maintaining the temperature of the water in the tanks until the water is purified; while cleaning the water in the tanks perform the entire period of time while they are attached to the docking station; detachment of the sea container when the water in the tanks has reached a temperature at which the living aquatic animals in it are in a state of hibernation; placing tanks with aquatic animals back in a refrigerated container and connecting to internal life support; cooling the water in the tanks by cooling the interior of the refrigerated sea container when the refrigerated sea container is disconnected from the docking station; performing air circulation through tanks with live aquatic animals; aerating water and creating an airlift effect; passing water in tanks through filters located in each tank, also due to the airlift effect.

The disadvantages of the known system and method for transporting live aquatic animals between shipping points are: high labor intensity when moving tanks filled with water and marine animals from the container to the connection points to the docking station and back to the container; at the same time, the filled tanks are installed in containers on pallets without fastening and fixing, which limits their stability and in the event of a big wave or collision with an obstacle during transportation, there is a risk of displacement and overturning of the tanks with marine animals, which leads to their death; low degree of water purification in tanks during transportation, which worsens the conditions for the existence of living marine animals; there are not enough funds to provide a life-supporting aquatic environment for live aquatic animals in tanks during container transport, so it becomes necessary to install intermediate docking stations or shorten the time intervals for transporting live aquatic animals in order to maintain their freshness and viability, since the available funds in the container only partially carry out water purification in tanks, therefore this container is not suitable for long-term, long-distance transportation of live marine animals.

The solution to this technical problem is to create a method for transporting living aquatic organisms and a system for its implementation, the use of which will eliminate the above disadvantages inherent in known systems and methods, increase the reliability of transportation of aquatic organisms and avoid new problems associated with intermediate transit transshipment of aquatic organisms from the sender to the final destination. recipient.

The technical result achieved when solving this technical problem is: the creation of a universal method of transporting hydrobionts between transshipment points and a life-supporting system for its implementation on the basis of a standard refrigerated container, the technical and operational characteristics of which take into account the infrastructure of transportation by sea, rail and road transport; increasing the duration of transportation of living aquatic organisms over long distances without compromising their viability and freshness, which makes it possible to make the method of transportation of aquatic organisms and the system for its implementation efficient and cost-effective. The method and system are easy to maintain and reliable in operation, so the need to monitor living marine aquatic organisms during transportation is reduced or completely eliminated.

The method for transporting live hydrobionts between transshipment points includes the following steps: placing live hydrobionts in containers filled with water and installed in a refrigerated container; connecting to the power supply a container equipped with means for cooling, aerating and circulating water in the containers during loading and transportation of aquatic organisms; carry out cooling, aeration and circulation of the aquatic environment in tanks, as well as filtration and purification of polluted aquatic environment in tanks with live hydrobionts.

What is new is that they circulate the aquatic environment between tanks with hydrobionts and the treatment system, aerate the aquatic habitat of hydrobionts, cool the aquatic environment in the tanks, while the polluted aquatic environment is additionally filtered and purified, passing through a biological treatment filter and automatically, if necessary, the system switches from an external power supply 380 V to autonomous mode from the device Batteries additionally installed in the container. Tanks with living aquatic organisms are permanently connected to the tanks by a purification system, in which water is purified using circulation pumps and filters for biological water purification. Also, it is possible to constantly aerate water in each tank circuit from two compressors through pipelines for compressed air distribution, while in case of disconnection of the refrigerated container from the external power supply of 380 V, one of the compressors automatically switches to power from the battery device, and the second is switched to the mode waiting, which will ensure uninterrupted operation of the system for 48 hours. The supply of purified water in each circuit can be constantly produced from two pumps through the pipelines of the treatment system, while in the event that the refrigerated container is disconnected from the external 380V power supply, one of the pumps automatically switches to power from the battery device, and the second is switched to standby mode. They cool water in containers with hydrobionts by cooling the interior of the refrigerated container, which will maintain optimal temperature conditions for hydrobionts during transportation. Contaminated water is purified through a biological filter when the refrigerated container is connected to a 380 V power source, which makes it possible to provide life-supporting parameters of the aquatic environment for living aquatic animals. Water circulation is carried out in tanks through pipelines connected to tanks with treatment systems by devices that create a difference in water levels, resulting in a circulation effect. Caps with position locks are installed on the containers filled with water and hydrobionts, which will prevent splashing of water from the containers and maintain the temperature of the aquatic environment in them during the transportation of live hydrobionts.

The system for transporting living aquatic organisms between transshipment points in the above manner comprises containers filled with water for keeping living aquatic organisms in a life-sustaining aquatic habitat during transportation, as well as a refrigerated container equipped with means for cooling, aerating and circulating water in said containers. What is new is that the system contains two circuits for keeping hydrobionts, left and right, independent of each other, located along the length of the container, which makes it possible to increase the reliability of its operation. Each circuit contains one tank with a cleaning system and four tanks for transporting hydrobionts. The water contained in each circuit circulates through the filter tank with the help of 2 circulation pumps, which allows, in the event of failure of one of them, the freshness remaining in the operation of the pump and maintain the circuit's performance in full.

The circuits in the container may additionally contain means for aerating water circulating between the tanks for keeping live aquatic organisms and the treatment system, which will ensure the specified temperature regime of the aquatic environment in the tanks during transportation of live aquatic organisms. Optimally, if the container will contain a pipeline for the withdrawal of untreated water from the tanks for keeping living aquatic organisms to the treatment system for its purification. The container may contain a pipeline for supplying purified water from the treatment system to tanks for keeping live aquatic organisms, which will ensure the uninterrupted operation of the system, improve the conditions for the existence of living marine animals. It is desirable that the system contain a pipeline for distributing compressed air from the external environment to each tank for aerating water inside tanks with live aquatic organisms, which will create healthy conditions for the implementation of the life cycle of aquatic organisms during their transportation. The refrigerated container may comprise an air circulation means in the form of a compressor which is separate from the means for cooling the water in the live aquatic holding tanks, and the air circulation means may be connected to a pipeline for distributing compressed air in the tanks. It is necessary that the treatment system tanks contain a circulation pump, a biological water purification filter, coarse filters, an activated carbon and zeolite filter, pH buffers and other water purification means used in the transportation of live aquatic organisms, which will allow to establish reliable uninterrupted operation of the system.

The invention is illustrated by graphic materials, where in Fig. 1 shows a plan of the refrigerated container of the system with two rows of permanently installed tanks for housing living aquatic organisms and their life support means, in Fig. 2 shows a cross section of the container at the location of the compartment with the cleaning system and the technological passage in the container between two rows of containers, at the far end of the passage, in the end part of the container, flotation equipment is permanently installed.

The proposed technical solution is illustrated by the example of using the method of transporting living hydrobionts and the system for its implementation.

For certain species of aquatic animals, long periods of transportation are required, therefore, there is a need for an individual method of their transportation and a life support system in which the temperature of the habitat of hydrobionts could drop to + 2С ° - + 3С °, that is, cool down to the hibernation mode temperature, which will allow hydrobionts to stay alive for a long time.

To implement the method of transporting living aquatic organisms in the system, a specialized refrigerated container of the 1AAA-S-012F type is designed, which is used to transport fresh and viable marine aquatic organisms in water-filled tanks over various distances. The container has no restrictions on transportation by means of transport, as it is universal for sea, road and rail transport. The overall dimensions of the container and the technology of its connection to a 380V power supply are similar to standard refrigerated containers, so it can also be used for overexposure of live seafood anywhere on land. The method of transporting hydrobionts and the life support system are efficient in terms of cost and energy costs, while during the entire process of cooling hydrobionts in hibernation mode, their aquatic habitat remains clean.

The system for implementing the method of transportation contains: 1. Tanks for hydrobionts; 2. Refrigerated container type 1AAA-S-012F; 3. Internal passage space; 4. Stationary refrigeration equipment; 5. Compressors; 6. Pipeline for air supply; 7. Feeding pumps; 8. Biological filter; 9. Pumps forcing; 10. Tanks with a cleaning system; 11. battery; 12. Compartment for activated carbon and zeolite; 13a. Pipeline supplying water; 13b. Drain pipeline; 14. Coarse filter.

Tanks (1) for keeping live hydrobionts are made of food-grade, chemically resistant extruded polypropylene according to TU 2293-008-73036980-2007 and TU 2293-003-81718162-2008 and meet the necessary certification requirements in force on the territory of the Russian Federation. They are adapted for the storage of live aquatic life, such as oysters, crabs, scallops, mussels, bivalves, finned or other marine animals, in a life-sustaining aquatic environment prior to transport, during transport, and after transport of live aquatic animals between shipping points. .

Tanks (1) for transportation of hydrobionts and tanks with a cleaning system (10) are permanently installed in the container (2). The container (2) is equipped with means to ensure cooling, aeration and circulation of water around the circuit during transport. Tanks with a cleaning system (10) contain means for providing a life-sustaining aquatic environment in the tanks (1) used during the transport of the container (2). These means include a circulation pump (7, 9) for circulating water between tanks with a cleaning system (10) and tanks (1), a biological water filter (8), coarse filters (14), an activated carbon filter and zeolite ( 12), neutral pH buffers and other water purification agents (see Fig. 1 and Fig. 2). The tanks with the cleaning system (10) are divided into at least three compartments and contain a filter for removing large particles, a biological filter and an activated carbon filter with zeolite (12). The fluid communication between each filter compartment is provided in parallel so that when fluid communication with the filter housing or filter is blocked, the remaining filters in the other compartments remain operational. Each filter compartment can be equipped with more than one filter, for example, of different types, but in such a way that the filters of one compartment are arranged sequentially one after the other of each other compartment relative to the water flow created by the siphon effect in the treatment system (10). In order for aquatic organisms to remain fresh and viable, it is necessary to maintain their habitat in containers (1) at a neutral pH value in order to create the best living conditions for aquatic organisms. Increasing the pH value from 7.2 to 8.2 can lead to the fact that the aquatic habitat of living aquatic organisms will become many times more toxic.

The biological water treatment filter (8) may also contain an ozonating device, biological filters, protein water purifiers, or any combination of these. The filter (8) must have a high capacity for cleaning the water circulating between the tanks (1) and the tank with the cleaning system (10) compared to the amount of water contained in the tanks (1) so that the water in the tanks can be quickly cleared. Therefore, to purify the water in the four tanks (1) of each circuit, the capacity of the filter medium in the tank with the cleaning system (10) must be such that the water can be purified or replaced within a period of time suitable for the specific aquatic organisms to be shipped or transported. in one or more containers (1).

In this system, to implement the method of transporting aquatic organisms, a typical insulated refrigerated container (2) is used, cooled by forced air cooling, adapted or designed for use on a ship, railway platform or truck when transporting aquatic organisms. Therefore, the system must be universal and designed for land transportation, for sea transportation, or a combination of them. A built-in refrigeration unit (4) is used on the refrigerated container (2) to maintain the set cooling temperature for hydrobionts during transportation, while the internal temperature of the cargo area of the container (2) can be adjusted from +26°С to -28°С. In addition, since the operation of the refrigeration unit requires electricity, an electrical device is installed in the REF container (2) together with the refrigeration unit (4), which can supply and store energy generated from the power of an attached diesel generator (NDGU) or a container ship. A refrigerated container (2) of this type contains an internal cargo space (3) enclosed by longitudinal side walls, end walls, a roof and a bottom, each enclosing element being an insulated two-layer wall structure. At the far end of the refrigerated container (2), stationary refrigeration equipment (4) is provided, which is widely used in marine refrigerated containers and contains an air circulation means in the form of a fan and a heat exchanger. The air taken from the inner space of the container (2) is driven past the heat exchanger by a fan, while the air flow is cooled and directed through pipelines into the inner space of the container (2) and into the tank (1) with live hydrobionts. The refrigerated container (2) used for the transportation of aquatic organisms is retrofitted with the possibility of being used in the system for transporting living aquatic organisms, therefore it contains a pipeline (13), a drain pipeline (13b) from each tank (1) to a connecting means on the tank with a cleaning system (10), designed to remove contaminated water from tanks (1) for cleaning in a filter medium (8). The supply pipeline (13a) is extended from the tank with the treatment system (10) to each tank (1) for the delivery of purified water. Also, a pipeline (6) is provided for supplying fresh air, which is connected at one end to the compressor (5), and at the other end is configured to be connected to each tank (1). The pipeline (6) is used to supply a compressed air flow to each container (1) in the case when the containers (1) of the system are loaded with live aquatic organisms. The air flow delivers the required oxygen to the tanks (1) and removes excess CO ₂ from the tanks (1) by simple aeration. Compressors (5) can deliver fresh air from the external environment, compress it and send it to tanks (1) through pipeline (6). The compressor (5) must be able to supply fresh compressed air at elevated pressure. Each container (1) is divided into two compartments adapted to contain a certain amount of water and equipped with a sealed lid. Tanks (1) are equipped with trays (not shown) for orderly placement of aquatic organisms up to the required height of the tank (1) and ensuring a safe gap between them. As a result, hydrobionts located at the bottom of the tank (1) are not damaged by their mass and possible activity during the period when they are not in a state of hibernation. The trays are made separate and have the ability to be attached to each other or to a supporting structure so that they can be easily removed together from the tank (1) and disassembled after unloading the aquatic organisms.

When the refrigerated container (2) is connected to an external power supply, the air and water are cooled by the refrigeration equipment (4), which is included as standard with the refrigerated container (2). The temperature at which living aquatic organisms of various species go into hibernation varies from species to species. However, the average temperature of the habitat of hydrobionts is within +2°С - +3°С.

If it is impossible to connect the container (2) to an external power supply, its design provides for two 225 Ah batteries (11), one for each circuit, to which the system switches automatically, which allows the compressor (5) and pump (7) to operate. ,9) within 48 hours, while the container (2) is not cooled in this case. During this period of time, the method of transportation consists in cleaning, aerating and cooling the water in containers (1), while the aquatic organisms are in a state of hibernation. The container (2) is delivered to the designated transshipment point REF connected to the generating power plant, and the temperature of the water in the tanks (1) is maintained at the level necessary for the aquatic organisms to be in a state of anabiosis, which makes it possible to transport and store living aquatic organisms in tanks (1) long time. At the designated delivery point, aquatic organisms can be accepted by the consignee and distributed to consumers fresh and viable.
