Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of biodiesel production equipment, and in particular to an auxiliary material dispersion device for biodiesel transesterification reaction. This device is used to disperse auxiliary materials during continuous transesterification reaction in biodiesel production. Background Technology
[0002] In the transesterification process of biodiesel production, the primary and secondary raw materials need to react in an alkaline environment with conditioning adjuvants. The batch reactor process, a conventional method for biodiesel production, involves feeding materials sequentially according to proportions. However, this method suffers from drawbacks such as long reaction time, uneven mixing of materials, high adjuvant consumption, easy saponification, low conversion efficiency, high labor intensity, low automation, and high labor costs. Therefore, the industry has developed processes to modify existing batch reactor production units into continuous transesterification reactors for biodiesel. However, this process requires the primary and secondary raw materials to be continuously and uniformly mixed in proportion before being fed into the reactor. Therefore, it is necessary to develop a device for dispersing adjuvants during continuous transesterification reactions in biodiesel production—a biodiesel transesterification adjuvant dispersion device. Summary of the Invention
[0003] The purpose of this invention is to provide a simple and compact auxiliary material dispersion device for biodiesel transesterification reaction, which has low manufacturing and maintenance costs and is reliable in use, so as to achieve uniform dispersion of auxiliary materials during continuous transesterification reaction in biodiesel production.
[0004] To achieve the above objectives, the auxiliary material dispersion device for biodiesel transesterification reaction of this utility model includes an auxiliary material feed pipe 1, a five-way valve 2, a primary porous disperser 3, and a secondary porous disperser 4. The primary porous disperser 3 is a circular annular tube with multiple evenly distributed equal-diameter discharge holes on its lower surface. The secondary porous disperser 4 is a triangular groove with multiple evenly distributed equal-diameter discharge holes at the bottom. Multiple triangular grooves are provided and horizontally welded to the lower surface of the circular annular tube, so that each discharge hole of the circular annular tube corresponds to a triangular groove with its opening facing upwards. One end of the auxiliary material feed pipe 1 is connected to the feed port of the five-way valve 2 located at the center, and the other end is connected to the auxiliary material groove. The four equal-diameter discharge ports of the five-way valve 2 are evenly distributed horizontally along the circumference. Each discharge port is connected to the circular annular tube through a connecting pipe. The auxiliary material dispersion device is suspended and fixed directly above the inside of the transesterification reactor through these four connecting pipes.
[0005] The auxiliary material dispersion device for biodiesel transesterification reaction of this utility model has the following technical features and beneficial effects:
[0006] 1. After being dispersed through the five-way equal diameter discharge port, the circular tube discharge hole, and the triangular groove discharge hole, the auxiliary materials enter the material reaction system in the reactor. This avoids the saponification caused by uneven dispersion of auxiliary materials in the reactor and excessive local concentration of auxiliary materials in the existing technology, while also reducing the consumption of auxiliary materials and improving the conversion rate. 2. The entire device has a simple and compact structure, low manufacturing and maintenance costs, and reliable operation. Attached Figure Description

[0010] The auxiliary material dispersion device for biodiesel transesterification reaction of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0011] Figures 1-2 As shown, the auxiliary material dispersion device for biodiesel transesterification reaction of this utility model includes an auxiliary material feed pipe 1, a five-way valve 2, a primary porous disperser 3, and a secondary porous disperser 4. The primary porous disperser 3 is a circular annular tube with multiple evenly distributed equal-diameter discharge holes on its lower surface. The secondary porous disperser 4 is a triangular groove with multiple evenly distributed equal-diameter discharge holes at the bottom. Multiple triangular grooves are provided and horizontally welded to the lower surface of the circular annular tube, so that each discharge hole of the circular annular tube corresponds to a triangular groove with its opening facing upward. One end of the auxiliary material feed pipe 1 is connected to the feed port of the five-way valve 2 located at the center, and the other end is connected to the auxiliary material groove. The four equal-diameter discharge ports of the five-way valve 2 are evenly distributed horizontally along the circumference. Each discharge port is connected to the circular annular tube through a connecting pipe. The auxiliary material dispersion device is suspended and fixed directly above the inside of the transesterification reactor through these four connecting pipes.
[0012] During production, the unit flow rate of the auxiliary material is input into the PLC control system, and the pumps for conveying the main and secondary materials and auxiliary materials are turned on. The main and secondary materials continuously enter the reactor, and the agitator inside the reactor is turned on. The auxiliary material is dispersed in four directions into the primary aperture disperser 3 through the four equal-diameter outlets of the five-way valve 2 via the auxiliary material feed pipe 1. In the annular tube of the primary aperture disperser 3, the auxiliary material flows into the secondary aperture disperser 4 directly below through the outlet holes. The auxiliary material in the triangular groove of the secondary aperture disperser 4 further expands the dispersion area and is dispersed on the upper surface of the material in the reactor through the evenly distributed equal-diameter outlet holes of the triangular groove, and is rapidly and continuously dispersed in the reaction system under the action of stirring.
