RU66035U1 - MEASURING DEVICE FOR DETERMINING THE WATER LEVEL IN RESERVOIRS INTENDED FOR OIL AND VISCOUS OIL PRODUCTS - Google Patents

Abstract

The proposed utility model relates to measuring equipment, in particular, to means for determining the liquid level, and can be used in the oil industry to determine the level of produced water in tanks with oil and viscous oil products. The solution to this problem is achieved by the fact that the tank is additionally equipped with the following equipment: a hatch, a rod, a metal ruler with an index plate and a roller device. Using a ring, the cylinder is put on the rod with the possibility of movement (up and down). A metal cable is fixed to the upper part of the cylinder with the aid of a bracket, which is connected to the index plate via a roller device. The plate is placed on a metal measuring ruler with the possibility of vertical movement. The ruler is attached to the tank using metal angles. The determination of the water level occurs when the cylinder reaches the upper layer of water, while it moves the index plate on a metal measuring ruler using a cable and a roller device. Water level is determined by the upper mark of the index plate. At the same time, the measurement production time is significantly reduced and the accuracy of determination is increased.

Description

The proposed utility model relates to measuring equipment, in particular, to means for determining the liquid level, and can be used in the oil industry to determine the amount of produced water in tanks intended for receiving, storing and dispensing oil and viscous oil products.

A universal device for determining the level of water and oil products in tanks with a capacity of up to 100 m ³ [1]. The device contains a main meterstick of a smaller diameter, with a water-sensitive paste applied to it, an additional meterstick of a larger diameter installed in a support, which is rigidly connected to the main meterstock. At the same time, a larger diameter meterstick has the ability to move relative to the main meterstock.

The disadvantage of this device is its low efficiency when used in tanks with a capacity of more than 100 m ³ , as well as difficulties with transporting the device to the place of use.

Also known is a device for determining the level of produced water in the tank [2]. This device contains a measured lot with a water-sensitive paste applied to it, which is placed in a hollow inner cylinder with a longitudinal slot for the receipt of the oil product. The inner cylinder is sealed inside the outer cylinder. It should be noted that the outer cylinder has the ability to move relative to the inner cylinder using a cable. The disadvantages of this device are: the complexity of manufacturing and the complexity of the production of measurement, as well as low efficiency in the presence of a large water level.

The closest in technical essence of the proposed utility model is a universal device for determining the levels of various liquids in tanks [3], including a flexible metal tape measure with a hollow cylinder fixed in the lower part. A load is rigidly attached to the base inside the cylinder. The load serves to maintain the cylinder in a vertical position at the phase boundary: oil-water. The masses of the cylinder and the load are selected taking into account the densities of oil and water. It should be borne in mind that the density of oil and water have different values.

The determination of the water level occurs after the cylinder reaches the oil-water phase boundary. Due to the selected mass, the cylinder penetrates through the oil layer and with the help of the load takes a vertical position in the upper layer of produced water. In this case, the beginning of the digital values of the roulette corresponds to the oil-water phase boundary. The determination of the water (oil) level is made according to the reading of the measuring tape. This tape measure will indicate the distance from the top of the tank to the water level H ₁ . In order to determine the amount of water, it is necessary to subtract the previously obtained value of H ₁ from the value of the base height of the tank H ₀ . The level of oil liquid is calculated by the value on the measuring tape left by the upper layer of oil N ₂ .

The disadvantage of this device is the fact that when lowering the cylinder deviates from the vertical position, which leads to an increase in measurement error. Also, the operator must spend considerable time on the measurement of oil and water. This time will consist of raising (lowering) the operator to the tank (from the tank), as well as lowering (raising) the device.

The proposed utility model solves the problem of increasing the efficiency of determining the level of produced water in tanks with oil (oil liquid). These signs are essential for solving the utility model problem, since the efficiency and accuracy of determination are increased

level of produced water in the tank with oil and viscous oil products, and the time required for this type of work is reduced.

The essence of the utility model is illustrated by drawings (figure 1, figure 2), which depict: the device in the context, and also a front view of the measuring ruler.

The following additional equipment is installed inside and outside the vertical cylindrical tank 1 for dark petroleum products: a hatch 2, a roller device 3, a rod 4, and a metal ruler 5, which is attached to the tank using metal angles 6. A plate 7 is fixed to the ruler, which the cable 8 moves horizontally depending on the position of the cylinder 9, which has a load 10 in the lower part. The load is intended for the cylinder to take a vertical position. The upper part of the cylinder is connected to the cable using the bracket 11. The cylinder has the ability to move horizontally across the rod using the ring 12.

The measuring device operates as follows. The cylinder with the help of a metal cable and a ring is lowered along the rod and is installed with the upper part at the oil-water phase interface 13. Using a roller device, the cable changes the position of the index plate. The top position of the plate on the measuring line determines the water level in the tank. At the same time, the measurement production time is significantly reduced and the accuracy of determination is increased. The reduction in time is due to the fact that the operator does not need to climb and descend to the tank to make water measurements. The operator can determine the water level using the proposed measuring device without climbing the tank, which increases the efficiency of his work in the production of water and oil measurements.
