The invention discloses a solid defoaming integrated device with a gas-liquid two-phase metering function. The solid defoaming integrated device at least comprises a prying seat and a defoamer which is fixedly connected to the prying seat. The solid defoaming integrated device is characterized in that a one-inlet and two-outlet three-way valve and a two-inlet and one-outlet three-way valve are respectively arranged at the inlet end and the outlet end of the defoamer; the inlet end of the one-inlet and two-outlet three-way valve is connected with a natural gas inlet pipeline; another two outletends of the one-inlet and two-outlet three-way valve are respectively connected with the inlet end of the defoamer and the inlet end of the two-inlet and one-outlet three-way valve; the outlet end ofthe two-inlet and one-outlet three-way valve is connected with a natural gas outlet pipeline; another two inlet ends of the two-inlet and one-outlet three-way valve are respectively connected with the outlet end of the defoamer and the outlet end of the one-inlet and two-outlet three-way valve; an emptying device is also arranged on a connected pipeline between the outlet end of the one-inlet andtwo-outlet three-way valve and the inlet end of the defoamer; a gas-liquid two-phase flowmeter is connected between the inlet end of the two-inlet and one-outlet three-way valve and the outlet end ofthe defoamer. The device has the advantages that a dosing device is optimized, a defomaing effect and the efficiency are improved, and the work intensity is reduced.
