Definitions

• the present invention refers to a sprinkling device applicable in the production of bitumen as well as in other productions in the oil chemistry and other industries.
• Sprinkling of the liquid occurs in drops or streams in the conventional sprinkling devices, which makes the phase contact between the liquid and the oxidizing agent insufficient when the reactor is operating at a sub maximal capacity, which has a negative effect on the speed of the reaction and hence the quality of the obtained product.
• the aim of the present invention is to remove the shortcomings of the conventional sprinklers by the creation of the sprinkling device, which allows an increase in the phase contact between the liquid and the oxidizing agent by the formation of a layer during the sprinkling of the liquid.
• a sprinkling device which includes a pipe for the charge of the liquid.
• the device is characterized in that also includes a sprinkling element, which upper surface is shaped as a concaved spherical segment, the radius of which is determined in accordance with the diameter of the reactor, for which the sprinkling element is designed.
• the pipe for the charge of liquid and the sprinkling element are positioned at a certain distance from each other and are created through at least one constructive element.
• the body of the sprinkling element represents thick metal cylinder.
• the body of the sprinkling element represents a hollow metal cylinder.
• the supportive elements are accomplished as rods, located in openings drilled in the body of the sprinkling element and fixed to the sprinkling element and the pipe by means of welding.
• Advantages of the sprinkling device lay in the increase of the phase contact between the liquid and the oxidizing agent by the formation of a layer during the sprinkling of the liquid on the concaved spherical segment.
• Figure 1 represents a schematic illustration of the sprinkling device
• Figure 2 shows a variant of accomplishment of the supportive elements of the sprinkling device.
• the sprinkling device (fig.1) consists of a pipe 1 , through which the liquid is charged, a sprinkling element 2, which is originally thick metal cylinder, but can also be accomplished as a hollow cylinder.
• the upper part of the cylinder is shaped as concaved spherical element 3, the radius of which is determined by the diameter of the reactor in which the sprinkling device is to be located.
• the supportive elements 4 (two or more) can have various constructive designs and are the link between pipe 1 and sprinkling element 2.
• Fig. 1 shows a variant of accomplishment in which the supportive elements 4 are accomplished as rods, located in the openings 5, drilled in the body of the sprinkling element 2.
• Fig. 2 shows another variant of accomplishment of the supportive elements 4.
• the elements 4 are bend so that they pass through the side walls of the body of the sprinkling element 2.
• the ends of elements 4 are fixed to the bottom 6 of the sprinkling element 2, which spans outside the body of the sprinkling element 2.
• the persons skilled in the art are aware of the other variants of accomplishment and fixation of the supportive elements 4.
• the distance between the head of the pipe 1 and the spherical surface 3 of the sprinkling element 2 is preliminary determined in accordance with viscosity and the speed of the charged product.
• the action of the sprinkling device is as follows:
• the liquid (oxidized bitumen, for example) is charged through pipe 1 to the spherical segment 3 of cylinder 2. This results in the layer distribution of the liquid on the top of the column.
• the obtained layer of the liquid as a result of the specific construction of the sprinkling element 2 serves as a barrier for the heavy fraction, which condenses and gradually falls down in the form of drops during which it is additionally oxidized.
• the light fraction passes through the layer in the upper part of the reactor and is passed for additional processing. It is obvious that the sprinkling device serves as a hydraulic tray.
