Description

Technical field

The present invention relates to a spray device for use in the production of bitumen, as well as in other industries in the petroleum, petrochemical and other industries.

BACKGROUND OF THE INVENTION

There are various types of spreading (irrigation) devices (“Processes and Apparatuses in the Chemical Industry”, Prof. Dr. Eng. ELENKOV, Dimitar G., Sofia 1970, “Technique”), such as the liquid is fed through a chute or pipe and is spread through other chutes or a dish. Pneumatic and centrifugal spreading devices are also available, the latter being the most efficient, but the energy consumption for spreading the liquid in them is the highest.

In the spraying devices used, the liquid is sprayed in drops or jets, whereby the phase contact between the liquid and the oxidizing agent is insufficient and the reactor does not operate at full capacity, which negatively affects the reaction rate and hence the quality of the product obtained. .

SUMMARY OF THE INVENTION

Therefore, it is an object of the present invention to eliminate the disadvantages of existing dispensers by creating a spray device allowing for increased phase contact between the liquid and the oxidizing agent by forming a diaper (spray) on the liquid spray.

The purpose is achieved by creating a spreading device including a tube for supplying liquid and characterized in that it also includes a spreading element, the upper surface of which is formed as a concave spherical segment, the radius of which is determined according to

the diameter of the reactor to which the spray element is intended. The fluid supply tube and the dispensing element are positioned at a certain distance from each other and are connected by at least one fastener.

In one embodiment, the body of the spreading member is a solid metal cylinder.

In another embodiment, the body of the spreading member is a hollow metal cylinder.

In both embodiments, it is advantageous for the fasteners to be constructed as bars, inserted into openings, drilled into the body of the spreading member, and secured to the spreading member and to the pipe by welding.

The advantages of the spraying device according to the invention lie in increasing the phase contact between the liquid and the oxidizing agent by forming a diaper (spray) on the spraying of the liquid onto the concave spherical segment.

Description of the accompanying drawings

Figure 1 is a schematic representation of the spreading device;

Figure 2 shows an embodiment of the mounting elements of the spreading device.

Examples of specific implementation

The spraying device (Fig. 1) consists of a tube 1 into which the fluid is supplied, a spraying element 2, which is preferably a solid metal cylinder, but may also be provided as a kkx cylinder. The upper surface of the cylinder is formed as a concave spherical segment 3, the radius of which depends on the diameter of the reactor in which the spraying device is located. The fasteners

3 elements 4 (two or more in number) can be structurally formed differently and are the connecting unit between tube 1 and spreading element 2. In FIG. 1 shows an embodiment of the fasteners 4 as bars inserted into openings 5 drilled into the body of the spreading member 2. The ends of the rods 4 are secured to the bottom of the element 2 by welding, for example.

Another embodiment of the fasteners 4 is shown in FIG. 2, In this embodiment, the members 4 are curved so that they extend along the side walls of the body of the spreading element 2. The ends of the elements 4 are engaged to the bottom 6 of the spreading element 2, which extends beyond the dimensions of the body of the spreading element 2. For Other means of performing and securing fasteners are obvious to those skilled in the art 4.

The distance between the tube head 1 and the spherical surface 3 of the spreading element 2 is predetermined depending on the viscosity and speed of the product being fed. Thus, as the velocity and viscosity of the feed product increase, the distance between the tube head 1 and the spherical surface 3 increases and vice versa.

The effect of the spreading device is the following:

The fluid (for example, oxidized bitumen) is passed through the pipe 1 to the spherical segment 3 of the cylinder 2. This produces a flattened spread of the fluid at the top of the column. The resulting diaper (zipper) from the liquid as a result of the specific design of the spray element 2 is a barrier for the heavy fraction, which condenses and gradually drops down as an additional oxidizing agent. The light fraction was passed through the diaper at the top of the reactor and submitted for further processing.

It can be seen from the description that the spreading device itself plays the role of a non-hydraulic plate.
