COMPRESSOR PLANT WITH A CIRCULATING CIRCUIT
The inventive compressor plant with a circulating circuit comprises a single-stage stream-handling compressor (2), at least two injectors (1), an input receiver (3), an output receiver (4), a filter (5), a valve (6) and a pressure gauge (7). The outputs of the parallel-placed injectors (1) are connected to the input of the inlet receiver (3). The active nozzles of the injectors (1) are connected to a pipeline connected to the output receiver (4) in which the pressure gauge (7) is located. The passive chambers of the injectors (1) are connected to a pipeline which is connected to the filter (5) provided with the input from the external gas medium. The output of the input receiver (3) is connected to the input of the single-stage compressor (2). The single-stage compressor (2), closing the circulating circuit, is connected by means of the pipeline to the output receiver (4), the exit of which is connected to a forcing pipeline. The use of the invention makes it possible to reduce material and energy costs.
