DETAILED DESCRIPTION

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] The object of the present invention is to provide a highly integrated integral ammonia compressor unit to solve the problems existing in the above-mentioned prior art and make the entire unit more compact and more integrated.

[0020] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Example 1 like Figures 1 to 4As shown, the embodiment provides a highly integrated integral ammonia compressor unit, comprising a common base 1, a driving motor 2, a compression host 3, at least one inter-stage cooler 4, at least one oil tank 5 and at least one gas-liquid separator 6, the driving motor 2, the compression host 3, the at least one inter-stage cooler 4 and the at least one oil tank 5 are all arranged on the common base 1, the driving motor 2 is in transmission connection with the compression host 3 through a shaft coupling, the compression host 3 is connected with the inter-stage cooler 4, the inter-stage cooler 4 is used for cooling the ammonia gas discharged after compression of the compression host 3, the gas-liquid separator 6 is connected with the gas inlet side of the compression host 3, and the oil tank 5 provides lubricating oil for the compression host 3. The arrangement form of each structure in the highly integrated integral ammonia compressor unit of the embodiment can greatly reduce the structural size of the entire ammonia compressor unit, and the entire unit is more simple, compact and high in integration.

[0022] In some specific solutions, the number of the inter-stage coolers 4, the oil tanks 5 and the gas-liquid separators 6 is the same, and is two.

[0023] In some specific solutions, the driving motor 2 and the compression host 3 are both arranged on the upper part of the common base 1, and the driving motor 2 is arranged behind the compression host.

[0024] In some specific solutions, the two inter-stage coolers 4 and the two oil tanks 5 are both arranged in the placing grooves arranged in the middle part of the common base 1. The inter-stage coolers 4 and the oil tanks 5 are ingeniously "hidden" in the common base 1. When the inter-stage coolers 4 and the oil tanks 5 are installed, they can be fixed by welding with the placing grooves, or a limiting structure can be arranged in the placing grooves to ensure the stability of the inter-stage coolers 4 and the oil tanks 5.

[0025] In some specific solutions, the inter-stage coolers 4 and the oil tanks 5 are arranged in the placing grooves in sequence, that is, the inter-stage coolers 4, the inter-stage coolers 4, the oil tanks 5 and the oil tanks 5 are arranged in sequence from front to back on the common base 1.

[0026] In some specific solutions, the inter-stage coolers 4 are arranged below the compression host 3, and the oil tanks 5 are arranged below the driving motor 2.

[0027] In some specific solutions, the two gas-liquid separators 6 are arranged on one side of the common base 1, and the two gas-liquid separators 6 are preferably arranged side by side in front of the common base 1.

[0028] In some specific solutions, the shapes of the inter-stage coolers 4 and the oil tanks 5 are both cylindrical, which is convenient for production and processing and is beneficial to the combination with the common base 1.

[0029] In some specific solutions, the shape of the gas-liquid separator 6 is also cylindrical.

[0030] The inter-stage cooler 4 and the oil tank 5 of the embodiment are integrated in the placement groove in the middle of the common base 1, and form an integrated structure with the common base 1 as the base for placing the compression main machine 3 and the driving motor 2. The gas-liquid separator 6 can be placed separately in front of the unit, and the main components of the entire ammonia compressor unit can be completely integrated into a whole, which greatly improves the convenience of installation, debugging and transportation and reduces the cost.

[0031] During the operation of the highly integrated whole ammonia compressor unit of the embodiment, the impeller in the compression main machine 3 is rotated and driven by the driving motor 2 to work, and the ammonia gas is compressed by the high-speed rotation of the impeller. In the intermediate compression process, after being compressed by several impellers, the high-temperature and high-pressure ammonia gas enters the inter-stage cooler 4 for cooling. After cooling, the ammonia gas is compressed by the remaining impellers in the compression main machine 3, so as to reduce the power consumption of the impeller and improve the efficiency. During the operation of the highly integrated whole ammonia compressor unit of the embodiment, the oil tank 5 continuously provides lubricating oil for the compression main machine 3, which is used for lubricating the bearings and gears in the compression main machine 3. The gas-liquid separator 6 is used to separate the liquid carried in the upstream ammonia gas, prevent the ammonia gas carrying liquid from entering the compression main machine 3, and avoid the impact of the liquid on the high-speed rotating impeller, so as to avoid damage to the impeller and affect the safe operation of the unit.

[0032] The highly integrated whole ammonia compressor unit of the embodiment includes the common base 1, the driving motor 2, the compression main machine 3, the inter-stage cooler 4, the oil tank 5 and the gas-liquid separator 6, has very good integration and integrity, and the entire unit system is very compact. The connection pipelines between the devices are more short and simple, the installation, maintenance, debugging and transportation are more convenient, the entire unit can be transported as a whole, occupies small area, and has lower overall comprehensive cost of the unit.
