Compressor inlet buffer tank

The utility model relates to a compressor inlet buffer tank. The compressor inlet buffer tank comprises a buffer tank body and a skirt. The skirt is connected with the bottom of the buffer tank body, at least two hand holes are formed in the skirt, a heat tracing coil is arranged in the skirt, and the inlet end and the outlet end of the heat tracing coil are connected with the two hand holes respectively through connecting pieces. The skirt is arranged at the bottom of the buffer tank body, the heat tracing coil is arranged in the skirt, the heat preservation function is added to the skirt of the buffer tank, and the problem of recycling deposited liquid at the bottom of the compressor inlet buffer tank can be effectively solved. In winter, when the compressor inlet buffer tank runs, temperature monitoring is conducted at the bottom of the buffer tank for multiple times, and temperature is above 30 DEG C every time, recycling compressor interlocking caused by the deposited liquid of the buffer tank cannot be
