Abstract

This invention relates to the storage of viscous products. The purpose of the invention is to reduce the heating time by increasing both the efficiency of heat exchange and the reduction of hydroresistance. The tank contains a casing; a casing installed in its lower part with inlet and outlet branch pipes for the coolant. Inside the casing there is a device for collecting the product in the form of an inverted glass, placed coaxially and with a gap relative to its walls. The tank is equipped with a horizontal collector in the form of an evolvent of a circle, the outlets of which are mounted on the casing and are diametrically opposed and tangentially forming the casing. 1 hp f-ly, 3 ill.

Inventory refers to storage tanks for petroleum products.

The goal is to reduce the warm-up time and increase the efficiency of heat exchange and decrease hydroresistance.

FIG. 1 shows a reservoir with a local cut-out in perspective; in fig. 2 is a section L-L in FIG. 1, in FIG. 3 a collector placed on the casing.

The reservoir for viscous products contains a housing, in the lower part of which a casing 1 is installed with a device for collecting the product, made in the form of an inverted glass 2. The glass 2 is placed in the casing coaxially with a gap, the ratio of their diameters is (0.33-0 , 5): 1, Inside the glass there is a hollow cylindrical element 3, in the upper part it is connected to one of the heat supply inlets 4, in the lower part of the glass 2 there are hollow axial blade vortexes 5, which communicate the polish cylindrical element 3 with a gap between the casing m 1 and stak-, number 2,

In the lower part of the casing 1 has a pipe outlet coolant 6.

The outlet pipe 7 of the product is located in the upper part of the glass 2. In the upper part of the casing 1 on it is installed a horizontal manifold 8 in the form of an evolvent of a circle. The collector 8 with its middle part is connected to another pipe 9 of the supply of the coolant. The end sections of the collector 8 are tangentially fixed on the casing 1 in diametrically opposite points.

The reservoir functions as follows.

In the gap between the claw 1 and the glass 2 through the pipe 9 for supplying coolant and horizontal manifold 8 is supplied coolant, and through pipe 4 to the cylindrical element 3. The coolant may be water with a temperature of 70-90 ° C or steam with a temperature of 120-200 C, or the exhaust gases of an internal combustion engine with a temperature of 160-220 ° C. The coolant enters the annular gap between the casing 1 and the cup 2 and into the hollow cylindrical element 3, twists and spirals along the surface of the stack 5

on 2 and hollow nJijntH; u 4 - - (rci of tomment 3, respectively. At that, a warming up viscous product, inside the cup 2 and a wall layer of the product around the casing 1, occurs. cup 2, the hollow chordichny element 3 is an additional source of heat, which intensifies the heating of the product inside cup 2 and creates conditions for intensifying the process of heat transfer by changing the magnitude and direction of the temperature gradient.

5 Simultaneously with the supply of coolant, the pump is turned on, which is connected to the outlet pipe 7 of the product. The product in the lower part of the reservoir, heated to 60-80 ° C (depending on the type of heat carrier), enters the cup 2 and is withdrawn from the reservoir. At the same time, the passage of the swirl vane blade 5, the product is twisted in a spiral, receives additional heat from the heat transfer medium, zazikhrelitel located in the cavity of the blades, and moves along the inner surface of the cup 2 to the sleeve 7 of the product outlet. Performance top

0 part of the glass 2 in the form of a cone contributes to the process of heat exchange inside the glass 2 and reduces the hydraulic resistance. This process leads to a sharp intensification of heat transfer,

5, the product heats up quickly, which is easily collected through the outlet pipe 7 of the product. In this case, the heating of the product is carried out directly in the vicinity of the casing 1, which reduces heat loss and allows the product to be pumped out with almost no residue.

Ensuring the ratio of the diameter of the glass 2 to the diameter of the casing 1 in the limit of (O, 33-0.5): 1 creates an optimal, from the point of view of heat exchange, the flow rate of the heat transfer medium in the gap.

Thus, equipping the tank with a horizontal collector made in the form of an evolvent, the ends of which are fixed on the casing tangentially to supply heat carrier to the gap between the casing and the glass, ensures the possibility of creating a circulating flow of heat carrier in the casing, which improves the heat transfer from heat carrier in a viscous product.
