Abstract

The invention relates to the construction and allows to increase the reliability of the reservoir drainage under any climatic conditions, as well as to simplify the operation of the reservoir. The tank contains a housing, a bottom, a floating bridge (PC) with a drain, equipped with a cap, suction pipe and drainage system for flexible and rigid sections. In order to avoid the occurrence of a product stored in a tank, on the PC surface in the event of a drainage system failure, the height of the receiving tube attached with an apron at the level of the central part of the PC is more than its maximum allowed draft. Cap vyusku vy-. Perforated at the bottom to drain water after opening the tap. At the same time, in the drainage system, due to the presence of liquid, a vacuum effect is created, due to which water is drained from the PC surface. To release hot steam supplied through the steam line, the tank is equipped with a heater in the form of a mountainous area with openings, 7 or more.

Description

The invention relates to the field of tank construction, in particular to tanks having a floating roof with a drainage system.

The purpose of the invention is to increase the reliability of the outlet in any climatic conditions and simplify the operation of the reservoir.

FIG. 1 shows a reservoir, Q vertical section; in fig. 2 — node I in FIG. one; in fig. 3 shows section A-A in FIG. 2; in FIG. 4, node II in FIG. one; FIG. 5 is a section BB in FIG. 4; in fig. 6 - joint unit - 5 flexible and rigid sections of the pipeline; Fig, 7 - section. B-B in FIG. 6,

The vertical cylindrical tank includes a housing 1, a bottom 2,1 shs- 20, and a shank 3 with a drain, located in the central part of the floating shank. The drain is a drainage system of rigid 4 and flexible 5 sections. Flexible area 25

5 attached with flange

6 to a suction inlet 7, provided with an apron 8, by means of which the nozzle 7 is attached to the floating

Consequently, flange 8 is loosened and a flexible section of the tank cleaning bases is replaced through this opening. The flexible section 5 is a hose of reinforced petrol-resistant rubber, and the rigid section 4 of the drainage system is a metal pipe supported on racks that are fixed to the bottom of the tank.

For normal operation of the water outlet in the period of snow precipitation, a heater is provided in the tank, which contains a toroidal section 11, covering the cap 9 and provided with openings for extracting hot steam. Due to this, defrosting of the upper part of the water outlet and the surface of floating ice occurs, and then evacuation of melt water,

The toroidal section 11 is connected by the steam line system 12 to the rigid section 4 of the drainage system through the valve 13, so that the hot steam is supplied to the drainage system both in the flexible and in the hard sections, and the drainage is completely thawed. The steam line is connected with a heavy accumulation of snow or ice on

the roof 3, while the apron 8 is located 30 floating crush 3,

If necessary, the toroidal section 11 of the heater can be moved to any part of the plan, the level of the central part of the floating roof, and the nozzle rises above it. The cap 9 of the inlet 7 is freely supported on the apron 8 and has perforations in the lower part to drain the melt water from the surface of the floating edge. 3. Dp evacuation of precipitation it is necessary that the drainage system drainage was liquid.
