Description

(54) DEVICE FOR HEATING VISCOUS OIL PRODUCTS IN A STEAM TANK

one

The invention relates to a power system and can be applied in national households using viscous petroleum products carried in tanks.

A device is known to heat up liquid liquids in a tank, consisting of two-knee pipes, a folding and folding mechanism, including a cylinder with a piston and a rod, and disks with cables 1.

A unit for heating and draining of viscous liquids on rail tank cars is also known, consisting of a jetting machine, a bottom draining device, a heat exchanger, and a circulation pump 2).

A known installation for heating a viscous product in railway tanks, in which the discharge hoses are enclosed in flexible ducts of individual links, enveloping the drive sprockets 3.

It is also known a device for heating hardened fats in railway tanks, consisting of a body with hinged two telescopic cylinders with nozzles in the last sections 4.

However, the equipment of discharge racks with known devices and installations requires significant capital expenditures. Due to the large number of moving parts, the reliability of their work is reduced.

5 A known portable foldable heating pad for heating viscous liquids in rail tank cars, consisting of a middle and two side pipes with openings for the release of steam in the lower part of the middle pipe and along the entire length of the side pipes, flattened at the ends 5.

A disadvantage of the known heating pad is the inefficient use of steam to heat the liquid at the ends of the tank due to its release through the holes in the middle pipe.

Claims (6)

The closest to the proposed technical essence and the achieved result is a device for heating viscous liquids in tanks with steam or other coolant, including a vertical rod and folding pipes connected to it with steam distributors with a nozzle at the end. The unfolding of the pipes is carried out with the help of a rotary action cylinder with gear 6. A disadvantage of the known device is the complicated and unreliable drive mechanism, the loss of steam energy due to supplying it before unfolding to the bottom of the tank. The purpose of the invention is to reduce steam consumption for heating viscous petroleum products in a tank. It also provides an increase in the reliability of the device. The goal is achieved in that in the device for heating viscous petroleum products in the tank with steam, including a vertical bar and connected with steam distributors, folding pipes with a nozzle at the end, in each steam distributor on the side facing the corresponding end of the tank, a hole with a closing element is made, folding pipes are connected to the latter with the possibility of closing said opening when unfolding. FIG. 1 shows the device in the initial and positioned position, general view; in fig. 2 — node I in FIG. 1 (steam manifold); in fig. 3 - node II in FIG. 1 (connecting nipple and clamp). The device consists of a vertical bar 1, forming with the help of a tee 2 and pipes 3 a T-shaped bar, at the ends of which are steam distributors 4 with a closing element 5 and a sleeve 6. In the latter there is a folding pipe 7 with a nozzle 8, which with the help of bar g 9 connected to a pipe 10 mounted on the bar 1. The pipe 10 has handles 11 with a brush 12 and a stopper 13. A fitting 14 and a cone 15 with an annular groove B are welded to the bar 1. The device works as follows after the device is lowered into the tank 14 flyover and Through rod 1, tee 2, pipe 3, cavity D, hole B in the steam distributor 4, the steam enters the heated oil and ensures its heating at a distance not less than the length of the folding pipes 7. After that, the stem 12 of the handle 11 is removed from the ring groove B cone 15 offset limiter 13, and pressing the handle and down the pipe 10 is lowered. In this case, the plugs 9 act on the folding pipes 7 and translate them into a horizontal position. The supply of steam to hole B is stopped, and the flow through cavity G, folding pipes 7 and nozzle 8 pairs heats a viscous oil product at the ends of the tank. Due to heating in the central part of the tank, the viscosity of the oil product decreases and folding of the folding pipes 7 is performed by a small force on the handles 11 and in the attachment points of step 9. By closing the opening B in steam distributors 4, rational use of steam is achieved to heat the oil at the end walls of the tank. The device is simple to manufacture and operate. Testing the prototype of the device shows that when the fuel oil is heated in a tank with steam with a temperature of 280 ° C and a pressure of 1.2 MPa, the emptying time of the tank decreases by 23% with a 43% lower steam consumption compared to In this case, fuel oil is prevented from escaping through the filling hatch in the initial period of purging, fuel oil water content is reduced, fuel oil and its more viscous components are removed from the bottom and end walls, and no charge is required. ka tank after draining. Apparatus of invention A device for heating viscous petroleum products in a tank with steam, including a vertical shank and folding pipes connected to it with steam distributors with a nozzle at the end, characterized in that, in order to reduce steam consumption for heating oil products, in each steam distributor on the side, facing the corresponding end of the tank, a hole is made with a closing element, and the folding pipes are connected with the latter with the possibility of closing the said hole when unfolding.
