Catalytic cracking device for biodiesel preparation

Abstract

The invention discloses a catalytic cracking device for biodiesel preparation, which comprises a reaction kettle, a feeding / discharging device, a heating furnace, a gas collecting tube and a rotary driving device, wherein the reaction kettle is used for accommodating used cooking oil; the feeding / discharging device is used for feeding a catalyst in the reaction kettle or outputting residues from the reaction kettle to the outside; the heating furnace is used for heating the reaction kettle; the gas collecting tube is used for collecting and leading out biodiesel gas in the reaction kettle; the rotary driving device is used for driving the reaction kettle to rotate; the reaction kettle is a hollow spherical shell, axle tubes are respectively fixed on the symmetrical two side shells of the reaction kettle, and are braced above the heating furnace through a first bearing; the output end of the rotary driving device is connected with the axle tubes, and drives the reaction kettle to rotate around the axial centers of the axle tubes; and a inlet / outlet of the feeding / discharging device is communicated with the reaction kettle, one end of the gas collecting tube is inserted into the reaction kettle, and the other end of the gas collecting tube extends out of the reaction kettle. According to the catalytic cracking device, used cooking oil is in full contact with an oil catalyst, and after the complete cracking of the used cooking oil is implemented, biodiesel gas is obtained.

Description

technical field [0001] The invention relates to a device for preparing biodiesel, in particular to a catalytic cracking device for preparing biodiesel. Background technique [0002] In food processing and catering life, some waste edible oils are often produced. In order to block the flow into the dining table again, they are generally processed and used as industrial raw materials. Among them, the waste edible oil is reacted with a special catalyst at a certain temperature through a reactor. It can be cracked to obtain biodiesel. However, in the catalytic cracking in the traditional reaction kettle, the waste edible oil and the catalyst cannot be fully contacted, the reaction is incomplete, and it is difficult to take out the residue after the cracking reaction. In addition, the waste heat after heating the reactor is not utilized, which leads to higher energy consumption and greater waste of resources.
