Abstract

FIELD: oil and gas industry. ^ SUBSTANCE: storage tank installed on the foundation includes cone bottom, wall of the housing and receiving-and-delivering devices, system of pipelines for pumping-in/pumping-out of oil products to the storage tank and out of it. Foundation is piled and has high foundation frame; the distance between foundation frame and ground level is more than diametre of pipelines for pumping-in/pumping-out of oil products to the storage tank and out of it; foundation frame is provided with through holes with diametre which is smaller than the foundation frame thickness; receiving-and-delivering device is arranged inside foundation frame, and system of pipelines for pumping-in/pumping-out of oil products to the storage tank and out of it is located in the gap between foundation frame and ground level so that gaps between pipelines and foundation frame from above and ground level from below are maintained. ^ EFFECT: providing constant control of the storage tank tightness during the whole service life. ^ 1 dwg

Description

The invention relates to the storage of oil and oil products, in particular to tanks for storing oil products.

The designs of existing reservoirs are known from the textbook for university students: Konovalov N.I., Mustafin F.M. et al. “Tank equipment”, Ufa: Design PolygraphService, 2005 (Pages 4, 5; sections: 1.1. Designs of steel vertical tanks; Fig.1.2, 1.3).

Known cylindrical tank for storing petroleum products - application No. 2007119164 (020889) - prototype.

A cylindrical tank for storing petroleum products mounted on a foundation containing a conical bottom, a housing wall, a floating roof with a sealing shutter, a dispensing device, a drainage device and a device for washing bottom sediments, characterized in that the dispensing device is located inside the foundation below a horizontal plane passing through the base the bottom cone, the drainage device and the bottom sediment erosion device are located below the top of the bottom cone, and the floating roof with a seal yuschim gate is adapted to move its retaining technological gap to the upper edge of the tank in the raised position until the bottom cone vertices in the lower position - prototype.

The disadvantage of this design is the inability to constantly monitor the tightness of the tank bottom.

The objective of the invention is to make it possible to continuously monitor the bottom of the tank throughout the entire service life and timely detect violations of the tightness of the bottom of the tank.

The problem is solved due to the fact that in the tank installed on the foundation, containing a conical bottom, the wall of the housing and receiving and distributing devices, the foundation is made of a pile with a high grillage. The grillage is made with through holes with a diameter smaller than the grillage thickness. The distance between the grillage and the ground level is greater than the diameter of the pipelines for pumping-pumping petroleum products into and out of the tank. The transfer device is located inside the grillage. The piping system for pumping and pumping petroleum products into and out of the tank is made in the gap between the grillage and the soil level while maintaining gaps between the pipelines and grillage above and the soil level from below.

Design features of the invention are illustrated in the drawing, where

shows a tank for storing petroleum products, side view.

The cylindrical tank for storing petroleum products has a conical bottom 1, a wall 2 of the housing. Acceptance devices 3 consist of a system of pipelines 4 and nozzles for pumping and pumping oil products into and out of the tank and are equipped with safety locking devices (not the subject of the invention). The tank is installed on a foundation with piles 5 and a high grillage 6, which is made with through holes 7. The distance between the grillage 6 and the soil level 8 is greater than the diameter of the pipeline 4 for pumping and pumping oil products into and out of the tank. The receiving and distributing device 3 is placed inside the grill 6. The piping system 4 for pumping and pumping petroleum products into and out of the tank is made in the gap between the grill 6 and the soil level 8, while maintaining the gaps between the pipelines 4 and the grill 6 above and the soil level 8 below.

The use of this invention makes it possible to continuously monitor the bottom of the tank.
