The invention relates to a device cleaning tank bottoms from precipitation viscous, high viscosity and thickening liquids mainly oil origin and can be used in the oil and petrochemical industry.

In the operation of the tanks on their plate is deposited a large amount of viscous, high-viscosity or thickening of precipitation, which reduces the useful volume and impede the normal operation. Removal of sediment is a complex and time-consuming operation. As stated in [1], effective methods of dealing with the accumulation of sediments in reservoirs has not yet been created. Used cleaning tank bottoms based on hydrodynamic and physico-chemical effects of jets of different washing machines RAM-1, MM-3, GEMS-2, GM and require the use of manual labor. Softened suspended sediment is removed from the tank Stripping pumps. Scraping the bottom of the tank a large amount of known devices requires several washing machines and a large number of people for maintenance. So, in [1] States that the scraping of the bottom of the tank with the capacity of 5000 m3requires 6 people. In the absence of scour machines tank cleaned manually with a shovel.

A device for cleaning tanks from bottom sediments [2], in the cat the rum for education radial annular jet of fluid, a cylindrical body with a flange, fixed with a gap above the bottom, provided with a movable prigruzkoj cowling installed outside the housing and having a curved lower edge. The device is installed on the bottom of the tank (tank), and is connected with the pressure pipe. In the absence of the fluid in the pressure line mobile shell falls to the bottom of the device, rasamma the internal cavity of the device and the vessel.

A disadvantage of the known device does not effectively dilute sediment in the tank in the form of asphalt, resin and paraffin deposits (ARPD), as is in the tank viscous or highly viscous residue prevents the rise of mobile prigoginei shell, i.e. the formation of a gap between the movable body and the bottom of the device [3]. In addition, in an unusable state in the internal cavity of the device for Milloy period cleaning of the bottom of the tank accumulates viscous or highly viscous sludge, also preventing lifting of the movable prigoginei shell, i.e. the formation of a gap between the movable sides and bottom.

The purpose of the invention is improving the efficiency of the device by forming a rotating fan-shaped annular jet scour fluid to preserve the useful volume of the tank, as well as exceptions to design mobile prigoginei shell to eliminate Ave is pastia education gap and after rotating fan-shaped annular liquid jet as a result of exposure to the viscous shell, high viscosity or thickening of sludge.

This objective is achieved in that the bottom of the device is provided with radial eccentric spaced dividers made in the form of plates with bevel one side, while the length of each plate is less than the radius of the bottom of the device on which it is mounted, the height of the plates exceeds a fixed value of the gap between the casing and the bottom of the device, and the flow rate of scour fluid is defined and maintained by pumping her pump.

When the washout of sludge thickening in the unit is heated to the required temperature to lose fluid.

Figure 1 shows a General view of the device; figure 2 - cross section I-I in figure 1.

The device comprises a bottom 1, gap 2, which is formed by the bottom of the device and the housing 3 with the flange and folded lower edges of the dividers 4 and the cone 5.

The device works in the following way:

After the pump and start feeding a blur of fluid in the device for erosion sediment around each device is set intensive rotational movement of the entire mass of fluid flowing through a fixed gap 2 formed by the bottom 1 of the device and folded lower edges of the body 3 of the device. Rotational movement of the radial fluid flow and its splosh is here at the exit of the gap 2 is provided by the cone 5 and dividers 4, made with a bevel on one side and having a length less than the radius of the bottom of the device.

In the process of testing were as follows.

The average speed that creates the rotary motion blur fluid at the exit of the gap, allowed to conclude that the application of the proposed device enhances the effect of washing and weighing the amount of scour liquid sludge deposits, because it is 9.9 m/s, considerably exceeds the critical velocity weighting sediment ASPO fan jet (0.2 m/s).

The location of the dividers flow device at an angle of 90° is optimal to create rotational motion.

The use of the present invention will constantly maintain the capacity of the tank at the level of the project, to reduce the intensity of the corrosion damage of the bottom of the morning of the lower belt steel tanks, and can also be used for erosion of bottom sediments in the vicinity of outlet fittings system subsurface fire suppression tanks.
