Description

Technical Field

[0001] The utility model relates to the technical field of ammonia synthesis, in particular to an ammonia synthesis start-up device. Background Art

[0002] Ammonia synthesis start-up unit is an industrial equipment used to synthesize ammonia. In the ammonia synthesis start-up unit, nitrogen and hydrogen react to generate ammonia under high temperature, high pressure and catalyst.

[0003] When ammonia is in use, it is compressed by a compressor to compress the ammonia into liquid, and the liquid is stored in a liquid reservoir. According to the needs of use, the liquid ammonia is injected into the refrigerant pump to cool the temperature. The cooled liquid ammonia is converted into gas and pressurized again by the compressor to achieve the recycling of the ammonia. However, in the process of collecting ammonia, ammonia is prone to contain liquid, which affects the compression process of the compressor. Therefore, when recycling the ammonia, it is necessary to separate the liquid in the ammonia through an ammonia gas-liquid separation device. Therefore, a device that is conducive to separating the liquid in the ammonia is needed. Utility Model Content

[0004] The utility model aims to provide an ammonia synthesis start-up device, which has the advantage of being conducive to separating the liquid in the ammonia gas, and solves the problem that in the process of collecting the ammonia gas, the ammonia gas is easily mixed with liquid, which affects the compression processing of the compressor.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an ammonia synthesis start-up device, comprising a base plate, an oil separator, a pump body, a connecting ring, a sealing cover and a compressor, wherein the compressor is fixed at the middle of one end of the upper side of the oil separator, and both sides of the lower end of the oil separator are fixed to the middle of one end of the upper end surface of the base plate through a supporting plate, a gas-liquid separation tank is fixed at the middle of one end of the oil separator located at the compressor, a filter membrane is fixed at the middle of the inner part of the connecting ring, and the filter membrane is placed at the upper end of the gas-liquid separation tank through the connecting ring, and the sealing cover is fixed to the upper end of the gas-liquid separation tank through a fixing buckle, and the middle of the upper end of the sealing cover is connected to the middle of one side of the compressor through a connecting pipe, and the middle of the side of the gas-liquid separation tank away from the oil separator is connected with an air inlet pipe, and the inside of the gas-liquid separation tank is fixed with a baffle at the middle of one side of the oil separator, and the middle of the lower end of the gas-liquid separation tank is connected with a connecting pipe, and the gas-liquid separation tank is connected to the pump body through the connecting pipe.

[0006] Preferably, the pump body is fixed to the middle of the upper end surface of the bottom plate away from the oil separator, and the pump body is located directly below the gas-liquid separation tank, and a delivery pipe is connected and installed in the middle of the end of the pump body away from the oil separator.

[0007] Preferably, the baffle is in an obtuse angle shape, and the inner side of the baffle corresponds to the air inlet pipe.

[0008] Preferably, the lower end of the compressor is connected to the interior of the oil separator, and the oil separator is columnar.

[0009] Preferably, the gas-liquid separation tank and the sealing cover are both circular, and the diameters of the gas-liquid separation tank and the sealing cover are equal, and the connecting ring and the filter membrane are both located between the gas-liquid separation tank and the sealing cover.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] 1. The utility model is conducive to achieving the effect of separating ammonia gas and liquid by arranging a baffle and a filter membrane. Ammonia gas is injected into the interior of the gas-liquid separation tank through the air inlet pipe, and the gas is pressed on the baffle plate. The liquid hits the baffle plate and can fall down in diameter, while the gas can enter the compressor upward through the connecting pipe. While the gas is upward, it can be filtered again through the filter membrane, which is conducive to filtering the liquid contained in the gas, thereby improving the effect of ammonia gas-liquid separation.

[0012] 2. The utility model is advantageous for the separate treatment of ammonia gas and liquid by providing a pump body and a compressor. After the ammonia gas and liquid are separated by the baffle and the filter membrane, the gas is further compressed into liquid by the compressor, and the compressed liquid enters the liquid reservoir, while the liquid in the ammonia gas and liquid is separated and concentrated in the gas-liquid separation tank. By starting the pump body, the liquid in the gas-liquid separation tank can be directly injected into the liquid reservoir. BRIEF DESCRIPTION OF THE DRAWINGS
