Description

Technical Field

[0001] The invention relates to the technical field of compressor buffering, and in particular to a novel compressor buffer tank. Background Art

[0002] Reciprocating compressors are widely used in natural gas, petroleum, and chemical industries. The working characteristics of reciprocating compressors are that the suction and exhaust airflows are intermittent and periodic. Therefore, it is inevitable to stimulate the fluid in the inlet and outlet pipes to present a pulsating state, so that the fluid parameters in the pipe change periodically with position and time, such as pressure, speed, and density, which is the so-called airflow pulsation. When the airflow pulsating fluid is transported along the pipeline, it will encounter elbows, reducers, branch pipes, valves, blind plates and other components, which will generate exciting forces that change periodically with time. Under the influence of the exciting forces, the pipeline will produce mechanical vibrations. The source of pulsation is the compressor cylinders at various levels set in the compressor. Some solutions in the prior art generally use the addition of pipeline supports to achieve the purpose of preventing the pipeline from producing obvious vibrations, which cannot control the airflow pulsation well, and ignore the influence of airflow pulsation on the air valves, pipelines, etc. of the compressor cylinder, thereby reducing the reliability and economy of the compressor cylinder; although some compressor cylinders are equipped with buffer tanks, if the volume is too small, it will not work. If the volume is large, it will occupy a large space, or it will not work far away from the compressor cylinder, and the economic effect is poor. Summary of the invention

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a new type of compressor buffer tank, which suppresses the air flow pulsation caused by the reciprocating motion of the compressor piston head by changing the flow direction and route of the gas through a new structural form. Specifically, an internal head and an internal gas pipeline are added to the inside of the buffer tank body, and air holes are opened on the pipeline, so that the gas forms a gas streamline of air inlet-internal pipeline-air hole-chamber-air outlet-compressor. The four air holes are evenly distributed at 90 degrees, and the air holes are aligned with the air outlet, which can achieve a good gas throttling effect. The end of the internal pipeline away from the air inlet extends out of the tank body, which can reduce the overall length and volume of the buffer tank while suppressing the gas pulsation, which can support the internal pipeline and save material costs.

[0004] The objective of the present invention is achieved through the following technical measures: a new type of compressor buffer tank, comprising a tank body, an internal pipeline, an air inlet, an air outlet, a first inner head, a second inner head and an air vent, the first inner head and the second inner head are respectively arranged inside the tank body, the first inner head and the second inner head divide the inside of the tank body into three independent chambers, the internal pipeline is arranged in the tank body and passes through the three chambers, air vents are arranged on the internal pipeline of each chamber, an air inlet is arranged at one end of the tank body, the air inlet is connected to the internal pipeline, an air outlet is arranged on the side wall of the tank body, and the air outlet is used to discharge the gas in the tank body.

[0005] Furthermore, there are three gas outlets, and each gas outlet discharges the gas in one chamber.

[0006] Furthermore, the air outlet corresponds to the position of the air vent in the corresponding chamber.

[0007] Furthermore, the number of the air holes is 4, and the 4 air holes are distributed on the same cross section of the internal pipe.

[0008] Furthermore, the cross section where the air holes are located coincides with the central axis of the air outlet.

[0009] Furthermore, the four air holes are evenly distributed on the circumference of the inner pipe.

[0010] Furthermore, the number of the air holes is 4, and the 4 air holes are distributed on the same cross section of the internal pipe.

[0011] Furthermore, the four air holes are evenly distributed on the circumference of the inner pipe.

[0012] Furthermore, one end of the internal pipe away from the air inlet extends out of the tank body.

[0013] Compared with the prior art, the beneficial effects of the present invention are: a new type of compressor buffer tank, which suppresses the air flow pulsation caused by the reciprocating motion of the compressor piston head by changing the flow direction and route of the gas through a new structural form.

[0018] like Figures 1 to 2 As shown, a novel compressor buffer tank includes a tank body 1, an internal pipeline 2, an air inlet 3, an air outlet 4, a first inner head 5, a second inner head 6 and an air vent 7. The first inner head 5 and the second inner head 6 are respectively arranged inside the tank body 1. The first inner head 5 and the second inner head 6 divide the inside of the tank body 1 into three independent chambers 8. The internal pipeline 2 is arranged in the tank body 1 and passes through the three chambers 8. The air vent 7 is arranged on the internal pipeline 2 of each chamber 8. An air inlet 3 is arranged at one end of the tank body 1. The air inlet 3 is connected to the internal pipeline 2. An air outlet 4 is arranged on the side wall of the tank body 1. The air outlet 4 is used to discharge the gas in the tank body 1. The internal head, the gas internal pipeline 2 and the air vent 7 are added inside the buffer tank body 1, so that the gas forms a gas streamline of the air inlet 3---internal pipeline 2---air vent 7---chamber 8---air outlet 4---compressor. The specific route, flow direction and volume change of the gas can greatly reduce the gas pulsation caused by the movement of the compressor piston head. Specifically, the gas enters the inner pipe 2 with a smaller pipe diameter horizontally through the air inlet 3, then flows into the larger tank 1 chamber 8 through the air vent 7 with a smaller aperture, and finally flows out to the compressor vertically through the air outlet 4 on the chamber 8.

[0019] There are three gas outlets 4 , and each gas outlet 4 is used to discharge gas from one chamber 8 .

[0020] The air outlet 4 corresponds to the position of the air holes 7 in the corresponding chamber 8. The number of the air holes 7 is 4, and the 4 air holes 7 are distributed on the same cross section of the internal pipe 2. The cross section where the air holes 7 are located coincides with the central axis of the air outlet 4. The 4 air holes 7 are evenly distributed on the circumference of the internal pipe 2. The 4 air holes 7 are evenly distributed, that is, the 4 air holes 7 are evenly arranged at 90 degrees on the outer circumference, and the air holes 7 are aligned with the air outlet 4, which can well achieve the throttling effect of the gas.

[0021] One end of the internal pipe 2 away from the gas inlet 3 extends out of the tank body 1. While suppressing gas pulsation, the overall length and volume of the buffer tank can be reduced, which can support the internal pipe 2 and save material costs.

Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements fall within the scope of the present invention to be protected.
