Embodiment
[0069] use figure 1 Doser shown, press figure 2 The setup shown was used for medium-scale experiments in the laboratory. Use high-temperature delivery gas to transport the normal-temperature FCC catalyst (brand name GRV-C) in the catalyst storage tank 22 to the destination container 27; preheat the catalyst in the delivery pipeline so that the catalyst enters the destination container 27 at a higher temperature .
[0070] The inner diameter D of silo 1 is 0.7 meters, the volume is 0.305 cubic meters, and the catalyst storage capacity is 300 kilograms; the lower limit storage weight of the catalyst is set to 50 kilograms, and the upper limit storage weight of the catalyst is 250 kilograms. The catalyst storage tank 22 and the destination container 27 are both vertical cylindrical structures with an inner diameter of 1 meter and a volume of 0.955 cubic meters. The pressure in the target container 27 was 0.55 MPa.
[0071] The silo 1 is supported on the load cell 7 through t...

The invention discloses an automatic catalyst feeder and an automatic catalyst feeding method, can be used for solving the problems in the conventional feeding technology that catalysts can not be delivered continuously, and only can normal-temperature catalysts be delivered to a target container. The automatic catalyst feeder is provided with a stock bin (1), a feeding pipe (2), a laying-off pipe (3), a discharging pipe (13) and a pressure-equalizing pipe (4), wherein a feeding valve and a third corrugated pipe are arranged on the feeding pipe, a laying-off valve is arranged on the laying-off pipe, a delivery valve, a first corrugated pipe and a second corrugated pipe are arranged on the discharging pipe, and a pressure-equalizing valve is arranged on the pressure-equalizing pipe; the laying-off valve serves as a regulating valve; the storage bin is supported on electronic weighing sensors arranged outside the storage bin by virtue of supports, and insulation boards are arranged at the bottoms of the supports; and insulation layers are arranged on the outer parts of the pipes, the vales and the storage bin. The invention also discloses the automatic catalyst feeding method with adoption of the feeder. The automatic catalyst feeder and the automatic catalyst feeding method are mainly applied to an FCC (fluid catalytic cracking) process in the fields of petroleum refining and petrochemical industries.
Description
technical field [0001] The invention relates to a catalyst automatic feeder and a catalyst automatic feed method, which are used to transport catalyst from a catalyst storage tank to a target container. Background technique [0002] In the fluid catalytic cracking (FCC) process of petroleum refining and petrochemical industry, powder catalyst is an important material participating in the reaction. Various catalyst delivery equipment are widely used in industrial sites, and the delivery equipment used to supplement catalyst consumption is generally called a feeder. [0003] In the past, manual feeding was used for catalyst feeding. Usually, the catalyst that needs to be replenished within a day was added to the destination container of the process unit (such as the FCC regenerator) within a few hours, resulting in unstable operation of the process unit. Moreover, manual feeding cannot measure the amount added, resulting in waste of catalyst. The powder material automatic me...
