The invention relates to a sand-containing gas sand collecting device in a gas well sand production and sand control simulation experiment. The sand collecting device can reasonably catch and collect a sand sample in sand-containing gas in an experiment process and can directly sort in accordance with meshes as required and measure gas flow simultaneously; the sand collecting device is characterized in that the upper part of the sand collecting device is of a cylindrical structure and the lower part of the sand collecting device is in the shape of an inverted conical body; from top to bottom, the sand collecting device is sequentially provided with a flow meter, an upper-bottom gland, an atomizing nozzle, a gas inlet, an inspection window and a multi-stage sand sample sorting device; the flow meter comprises a filter element and is capable of monitoring gas flow after sand is removed from gas; the upper-bottom gland is fixedly connected to the sidewall of the sand collecting device by virtue of a bolt and is provided with a seal gasket; the atomizing nozzle is arranged above the gas inlet; by virtue of water mist sprayed from the atomizing nozzle, residual sand in the gas can be caught; the inspection window can be used for monitoring change in water level in real time; and the multi-stage sand sample sorting device is located at the lowest side of a tank body and is used for immediately sorting the sand sample according to a requirement on meshes, so as to save time.
