Description

FIELD OF TECHNOLOGY

The utility model relates to a reservoir for anti-water crystallization fluid (DSCL) used in the field of aviation fuel supply.

LEVEL OF TECHNOLOGY

PWKZH are added to fuels for gas turbine (jet) engines, refueled in aircraft, in order to reduce the likelihood of water crystal formation in fuel tanks during flight. Reservoirs for HPLC, in particular, are used in the systems for dosed injection of HPLC in aviation fuel during refueling of an aircraft, which are components of ship aviation fuel supply systems (SATO), and are installed next to fuel transfer pumps operating when refueling aircraft.

Reservoirs for PWKZH are intended for storage and delivery of PWKL and usually contain a cylindrical body having means for receiving and means for issuing PWKZH.

A similar tank is known, for example, from the source / 1 / "Horizontal steel cylindrical tank RGS-50" // URL: https://all-pribors.ru/opisanie/75933-19-rgs-50 (date of access 09.08.2021) or from the source / 2 / "Consumable and control reservoirs for high-pressure water supply" // URL: http://www.agregatnpo.ru/production/obor-pvk/rk-02.html (date of access 09/08/2021). Described in the source / 2 / the reservoir for the DRC was chosen by the applicant as the closest analogue of the utility model.

According to the requirements of national standards, reservoirs for PVCL must be connected to deaeration lines, ensuring communication of the free space of the reservoir with the atmosphere. In this case, during the operation of the tank, outside air enters the inner space of the tank through the deaeration lines. The water contained in the atmospheric air leads to the watering of the LHCF inside the tank, and, consequently, to a significant deterioration in its quality. Thus, there is a need for dehumidification of atmospheric air that enters the reservoir for the DRCF through the deaeration line.

Known reservoirs for PWCI do not contain drainage means to prevent watering of the PWCF in the reservoir.

Based on the foregoing, the technical problem to be solved by the utility model is to ensure continuous dehumidification of the atmospheric air entering the reservoir for the LHCF, thereby preventing the deterioration of the quality of the LHCF contained within the reservoir.

DISCLOSURE OF THE USEFUL MODEL

To solve this technical problem, a reservoir for anti-water crystallization liquid (DSCL) is proposed, made with the possibility of storing and dispensing PWCF, containing a cylindrical body with a means for receiving PWCF and a means for issuing PWCF.

According to the utility model, the tank body is equipped with an air dehumidification device adapted to be connected to a deaeration pipeline for entering atmospheric air into the body and containing a drying agent storage chamber for drying the incoming atmospheric air from water molecules, and the drying agent storage chamber has a viewing window.

Thus, the proposed reservoir allows for dehumidification of the atmospheric air entering the reservoir from water molecules, monitoring the state of the desiccant through the viewing window for its timely replacement, thereby providing the possibility of continuous dehumidification of the air entering the reservoir for PVCL through the deaeration line.

According to a variant of the invention, the drying agent is an indicator silica gel-indicator in the form of grains having a first color at a relative humidity of 20% and a second color at a relative humidity of 50%.

According to a variant of the utility model, the air dehumidification device is made in the form of a cylindrical body forming a drying agent storage chamber, having a support flange for connection to the tank body and a removable flange cover adapted to be connected to the deaeration pipeline.

BRIEF DESCRIPTION OF DRAWINGS

Further, the utility model is described in more detail with reference to the attached drawings, in which:

in fig. 1 shows a perspective view of the reservoir for the PWCI according to the utility model;

in fig. 2 is a perspective view of the dehumidifying device of the tank of FIG. one.

IMPLEMENTATION OF THE USEFUL MODEL

Shown in FIG. 1, the reservoir 1 for the PVCL according to the utility model contains a cylindrical body 2, made, for example, of steel and having means 3 for receiving the PVCL and means 4 for issuing the PVCL, made in the form of branch pipes, at the ends of which there are connecting flanges for connection to the supply line of the PVCL and the dispenser PVKZH, respectively.

According to the invention, the reservoir 1 for the LHCF can be a reservoir for storing the LHCF under the "nitrogen cushion". In this case, the reservoir is also equipped with a nitrogen receiving means 5 in the form of a branch pipe with a connecting flange for connection to a nitrogen pipeline.

The cylindrical shape of the body 2 of the reservoir 1 for the PACL eliminates the creation of stagnant zones that contribute to the accumulation of contaminants in the PACL during its storage, facilitating the maintenance of the tanks during operation, during which the inner surfaces of the body are cleaned manually using cotton napkins.

Optionally, the reservoir 1 for PWCI can provide for the presence of a bypass roller level indicator 6, designed for visual indication of the level contained in the reservoir for PWC.

According to the utility model, the reservoir 1 for the LHCF is equipped with an air dehumidification device 7, the purpose of which is to dehumidify the atmospheric air entering the LHCF tank through the deaeration line from water molecules. The design of the dehumidifier is shown in more detail in FIG. 2.

In this embodiment, the air dehumidifier 7 comprises a cylindrical body 8 forming a storage chamber for the desiccant. The casing 8 of the air dehumidifier has a support flange 9, made with the possibility of connecting to the casing 2 of the reservoir 1 for PVCL, for example, by means of a special branch pipe with a mating connecting flange. In the upper part of the dehumidification device 7, a flange cover 10 is provided, which closes the storage chamber of the desiccant substance and is configured to be connected to the counter flange of the deaeration pipeline.

For the manufacture of a reservoir for high-pressure water and air drying and air dehumidification devices according to the utility model, materials are used that are traditionally used in this field of technology and comply with national standards, in particular GOST R 18.3.01-2016, GOST R 18.12.02-2017, GOST R 18.12.03- 2018, GOST 34347-2017. These materials are well known to those skilled in the art and are not discussed in detail in this application.

In accordance with an embodiment of the invention, an indicator silica having moisture-absorbing properties and changing its color depending on the relative humidity of the environment is used as a drying agent placed in the chamber of the air drying device.

In particular, the indicator silica gel used in accordance with the utility model can be an indicator silica that complies with the GOST 8984-75 standard.

Such a silica gel indicator has a first color (from blue to light blue) at a relative humidity of 20% and a second color (lilac or pink) at a relative humidity of 50%.

According to the utility model, the drying agent storage chamber has a viewing window 11 designed to control the color of the drying agent contained in it.

According to an embodiment of the invention, the dehumidifier may have more than one viewing window 11, for example two viewing windows 11.

It is clear from the above description of the reservoir for PVCL according to the invention that all of its components are connected to each other by assembly operations by means of known fastening means and are in functional and structural unity.

In the course of operation of the reservoir for the PVCL according to the utility model, atmospheric air is dehumidified through the deaeration line connected to the upper flange of the flange cover 10 of the air dehumidifier. At the same time, the color of the drying agent in the drying agent storage chamber is periodically monitored through the viewing window 11 of the storage chamber. Matching the color of the drying agent in the storage chamber to the first color is an indicator of the norm and a condition for the continued operation of the tank. If the color of the desiccant in the storage chamber changes to a second color, the charge of the desiccant in the chamber is replaced.

According to the utility model, the design of the reservoir for the HFKL provides for the possibility of its use in ship aviation fuel supply systems (SATO), located both in the below deck space and on the deck of the ship - on the runway or near it.
