Abstract

The invention relates to a grid plate type reciprocating compressor pipeline air flow pulsation attenuation device, the attenuation device includes a cylinder body, a pulsation attenuation chamber is formed inside the cylinder body, a head is provided at the front end of the cylinder body, and an inlet method is provided at the front end of the head Lan, the pulsation attenuation cavity is provided with a deflector grid, and the deflector grid is set as an inclined structure; the rear end and front end of the cylinder are set as a mutually symmetrical structure. It can solve the problems of airflow pulsation and impact vibration that exist in the prior art when large-scale reciprocating compressor units are sucked and exhausted, making it wide-band, small in size, convenient in processing, and high in efficiency; it is aimed at traditional airflow pulsation attenuators In particular, the ordinary buffer tank can significantly reduce the volume. Under the condition of producing the same pulsation suppression effect, the volume of the device is significantly reduced. Compared with the buffer tank with a perforated plate, the device can reduce the air flow pressure drop loss.

Description

technical field [0001] The invention belongs to the technical field of air flow pulsation suppression for reciprocating compressors, and relates to a grid plate type air flow pulsation attenuation device for pipelines of reciprocating compressors. Background technique [0002] Due to the intermittent nature of the suction and exhaust process of the reciprocating compressor, the pressure and velocity of the airflow change periodically, that is, the pulsation of the airflow is generated. In the normal operation of the reciprocating compressor unit, the pulsation of the air flow is inevitable. However, when the pulsation is too large, the entire compressor and its piping system will vibrate violently, resulting in fatigue of the piping system and its accessories, resulting in catastrophic accidents such as pipeline leakage, rupture, and explosion; even severe damage to the air valve. The working environment will accelerate the damage of the air valve and make the compressor un...
