Description

The utility model relates to the equipment of ventilation systems, in particular, for the removal of warm air from the sound-heat-insulating casing (SSHT) of the gas-pumping unit (GCU) and its distribution for blowing the service area of shut-off and control valves (SRA) of centrifugal blowers (CBN) piping.

A known method of removing warm air from the noise and heat-insulating casing of the GPU, selected as a prototype, is based on the use of an exhaust fan (VO) Ts4-70 with an electric motor with a power of 30 kWh, and an air duct system in which warm air is removed to the service area of the ZRA piping of the TsBN locally without its distribution over the entire width of the service area of the ZRA of the CBN piping.

The disadvantages of this setup are:

increased electricity consumption. energy during the operation of the GPU due to the use of a more powerful electric motor;

lack of air duct system for distributing the exhausted thermal air from the sound-heat-insulating casing of the gas compressor unit over the entire width of the service area for the ZRA of the central bank piping;

lack of adjustable rotary nozzles for point orientation of air flows in space;

the absence of rubber spacers at the point of attachment of the frame (VO) Ts4-70 to embedded metal structures and, as a result, the likelihood of vibration during operation of the suction fan.

formation of ice on the service platform and flights of stairs of the TsBN piping and the likelihood of a worker falling from the surface of the same level;

the probability of freezing and malfunctioning of the ball valve drives of the CBN piping during periods of low ambient temperatures.

The objective of the utility model is to remove thermal air from the CHP GPA and distribute it for blowing over the entire width of the service area of the ZRA of the CBN piping.

A device for distributing air flows discharged from the heat and noise insulating casing of the gas compressor unit operates as follows.

Through the suction air duct (8), the soft insert (7) and the PK 700×1000 conical transition (6), the warm air removed from the KSHP during GPU operation enters the suction fan VRAN 6-10-V (2), driven using an electric motor (4) with a power of 11 kWh, located on the power frame (3). Further, warm air enters the discharge air duct of a rectangular section 750×700×400 mm (10) and, having passed through the soft insert (11), changes its direction of movement from vertical to horizontal in the outlet P90 750×700×500 mm (13). After that, through the rectangular air duct 750×700×600 mm (14), warm air is supplied to the collector (16) of circular cross section. From the collector (16) warm air is distributed through adjustable nozzles (17) for blowing. The rotation of the adjustable nozzles (17) around its axis along the guides (20) produces a point orientation of the air flows to blow the service area of the ZRA of the CBN piping over its entire width.
