Description
Technical Field
The utility model relates to a field of natural gas transportation technique, concretely relates to novel exhaust buffer tank.
Background
The reciprocating compressor has an intermittent discharge characteristic which causes an uneven flow of gas in a pipe of the reciprocating compressor, thereby causing an uneven flow rate of discharge gas of the reciprocating compressor, resulting in vibration in the reciprocating compressor and in a pipe connected to the reciprocating compressor. The pulsation of air flow in the body of the reciprocating compressor can cause unstable outlet pressure and unstable air supply of the reciprocating compressor and influence the working efficiency of the reciprocating compressor; the resonance of the reciprocating compressor body can be caused, and the service life of the reciprocating compressor is short. The vibration of the pipe connected to the reciprocating compressor may cause the pipe wall to be damaged due to fatigue failure, resulting in a high replacement frequency of the pipe.
In order to reduce the adverse effect of vibration on the reciprocating compressor, a mode of connecting a buffer tank at an inlet and an outlet of the reciprocating compressor is mostly adopted. The buffer tank is an important accessory device of the reciprocating compressor and has two types of suction and exhaust. The exhaust buffer tank is connected at the outlet of the reciprocating compressor, and the exhaust buffer tank can effectively reduce the unevenness of air flow and the vibration of a pipeline caused by air flow pulsation.
In the field of natural gas transportation, an exhaust buffer tank plays a role in buffering gas vibration in a mode of throttling gas flowing through the buffer tank. The exhaust buffer tank is a hollow tank body with a built-in rigid conveying pipe fitting. The types of the exhaust buffer tank include a single volume type and a filter type. The middle part of each rigid conveying pipe fitting arranged in the single-volume exhaust buffer tank is communicated and is fixedly connected with a cavity in a coaxial manner; the middle part of each rigid conveying pipe fitting arranged in the filter type exhaust buffer tank is communicated with two cavities fixedly connected with the same axis, the two cavities are not in direct contact, and a throttling orifice plate is arranged in the rigid conveying pipe fitting between the two cavities.
The orifice plate is a rigid plate fixedly connected inside the rigid conveying pipe fitting, and the middle part of the rigid plate is provided with an orifice with the aperture smaller than the pipe diameter of the rigid conveying pipe fitting. The single-volume type exhaust buffer tank realizes buffering by changing the volume, and the filter type exhaust buffer tank realizes secondary buffering by a cavity. Filter type exhaust buffer tank compares in single volume type exhaust buffer tank, and buffering effect is better.
When using filter type exhaust buffer tank on the reciprocating compressor of one-level double-cylinder, the orifice plate receives the washing away of flowing through the air current for a long time, and orifice plate department takes place wearing and tearing or warp easily, leads to the aperture grow, influences the orifice plate and to the throttle effect of flowing through the air current, has increased exhaust buffer tank inner part and has changed the frequency, has increased the fund and the artifical input of exhaust buffering.

Detailed Description
As shown in figure 1, the air inlet of the novel exhaust buffer tank is connected with a one-stage double-cylinder reciprocating compressor. The exhaust buffer tank is a cylindrical tank body with a cavity. Two filtering tubes are fixedly connected in the tank body, and the two filtering tubes are hollow straight steel tubes with openings at two ends. The two filter pipes play a role in throttling the gas flowing through the exhaust buffer tank.
The two filters comprise a first filter 6 and a second filter 4. Three cavities which are distributed coaxially are arranged in the tank body, and the three cavities are a first cavity, a second cavity and an expansion cavity in sequence. The first filter tube 6 penetrates through the second cavity and penetrates into the first cavity and the expansion cavity, and the first filter tube 6 penetrates through the first cavity and the expansion cavity, so that gas can directly enter the expansion cavity from the first cavity; the second filter 4 penetrates the second cavity and the expansion cavity, and the second filter 4 penetrates the second cavity and the expansion cavity, so that gas can directly enter the expansion cavity from the second cavity. The three cavities, the first filter tube 6 and the second filter tube 4 are key parts for realizing gas throttling of the tank body.
The first cavity and the second cavity are separated through a first seal head 1 fixedly connected inside the tank body, and the second cavity and the expansion cavity are separated through a second seal head 5 fixedly connected inside the tank body. The first seal head 1 and the second seal head 5 are both made of steel plates, and the steel plates have certain pressure resistance to gas entering the tank body. The space of three cavities has been injectd in the setting of first head 1 and second head 5, has reduced the exhaust buffer tank during operation, and the pressure fluctuation that three cavity volume changes caused has improved the stability of exhaust buffer tank during operation.
The first seal head 1 and the second seal head 5 are both hemispherical seal heads. The spherical center of the hemispherical head faces the expansion cavity, and the central line of the hemispherical head is collinear with the axis of the tank body. When first head 1 is hemispherical, when gas contacts first head 1, can form the turbulent flow at first head 1 edge, reduce the pressure of gas to the junction of first head 1 and jar internal wall, reduce the change frequency of first head 1. The function of the second end socket 5 is similar to that of the first end socket 1.
The first filter tube 6 is supported by the first seal head 1 and the second seal head 5 at two points, and is stable in working. Compared with the first filter tube 6, the second filter tube 4 is only supported by the second seal head 5 at one point, and can easily generate reciprocating vibration around the second seal head 5 during working. In order to reduce the occurrence of the situation, a supporting plate 7 is fixedly connected to one end, close to the exhaust port 8, of the second filter pipe 4 in the expansion cavity, and the other end of the supporting plate 7 is fixedly connected with the inner wall of the tank body. The support plate 7 is arranged to stabilize the position of the second filter tube 4 with respect to the tank. The second filter tube 4 realizes two-point support of the tank body and the second seal head 5, and the operation is stable.
And a connecting plate 2 is fixedly connected between the first filtering tube 6 and the second filtering tube 4, and the connecting plate 2 is arranged in the second cavity. The connecting plate 2 stabilizes the relative positions of the first filter tube 6 and the second filter tube 4, thereby further increasing the stability of the first filter tube 6 and the second filter tube 4 during operation. The connecting plate 2 and the supporting plate 7 are both made of steel plates, and the cost is low.
The top of the first cavity is provided with a first air inlet 9, the top of the second cavity is provided with a second air inlet 3, and the side surface of the expansion cavity is provided with an air outlet 8. The reciprocating compressor with the primary double cylinders is provided with a first exhaust port and a second exhaust port, the first exhaust port is connected with the first air inlet 9, and the second exhaust port is connected with the second air inlet 3. The exhaust port 8 is used to deliver gas output from the reciprocating compressor.
