Description

Horizontal gas-liquid separator

Technical Field

The utility model relates to a vapour and liquid separator technical field, concretely relates to horizontal vapour and liquid separator.

Background

With the increasing social requirements on energy conservation and environmental protection, how to improve the energy efficiency ratio of air conditioners and refrigeration equipment becomes more important. At present, in the field of refrigeration and air conditioning, a screw type or centrifugal water chilling unit is generally adopted in a refrigerating unit of a large central air conditioner and a freezing and refrigerating place, a screw type or centrifugal compressor is adopted, a flooded type or falling film type evaporator is matched for use, when the load fluctuates, refrigerant liquid in the evaporator may enter the compressor along with return air, but the return air and liquid carrying are avoided when the compressor runs. If refrigerant liquid enters the screw compressor, the oil film of the rotor of the compressor is damaged, the lubrication of the rotor is disabled, and the rotor is dry-ground or even locked. If the refrigerant liquid enters the centrifugal compressor, the abrasion of the blades of the compressor can be caused, and particularly, in the currently used magnetic suspension compressor, the return air and the liquid bring great harm to the compressor, so that the damage to the compressor is caused.

The existing flooded or falling film evaporator is difficult to completely stop the air return and liquid entrainment when the working condition and the load fluctuation change, so that the key for improving the technical improvement of the refrigeration system is how to prevent the air return and liquid entrainment of a compressor, particularly a magnetic suspension centrifugal compressor, and improve the system reliability.

Disclosure of Invention

To the technical problem that prior art exists, the utility model provides a horizontal vapour and liquid separator to the realization is solved the compressor and is returned gas and take the liquid problem under the prerequisite that does not influence the system efficiency.

The utility model provides a pair of horizontal vapour and liquid separator, vapour and liquid separator includes:

a barrel; end cover plates are arranged at two end parts of the cylinder body, and the inside of the cylinder body is divided into a first chamber and a second chamber through a filter screen liquid remover; the bottom of the first chamber is provided with an air inlet, and the side part of the first chamber is provided with an air outlet; a liquid outlet is formed in the bottom of the second chamber;

a return air reducer pipe; one end of the air return reducer pipe is connected with the air outlet, and the other end of the air return reducer pipe penetrates through the filter screen liquid remover to be connected with the air return bent pipe in the second cavity.

Preferably, the inner diameter of the return air reducer gradually increases from the first chamber to the second chamber.

Preferably, the outlet of the return air elbow is arranged upwardly.

Preferably, a guide plate is arranged in the second chamber and between the filter screen liquid remover and the air return bent pipe.

Preferably, the top of the cylinder is provided with a safety valve seat.

Preferably, the air inlet is provided with an air inlet connecting pipe, and the air outlet is provided with an air outlet connecting pipe.

Preferably, the filter screen liquid remover is a stainless steel screen liquid remover.

Compared with the prior art, the utility model discloses following beneficial effect has: compare in the traditional vapour and liquid separator who goes up the interface, the utility model discloses with the air inlet setting in the lower part, the gas outlet setting is at the lateral part, compact structure, and the volume is less, can not increase the original size of unit. In addition, this implement neotype horizontal vapour and liquid separator built-in stainless steel net knockout and return gas reducing pipe, the resistance is little, and gas-liquid separation is efficient, can effectively stop liquid entering compressor.
