Description

REAGENT DOSING INSTALLATION g The utility model belongs to the field of oil production and preparation systems for oil companies and is intended for volumetric pressure dosing of liquid demulsifiers and corrosion inhibitors in technical systems of oil, petrochemical and other industries. A known unit for dosing chemicals / I /, which is a thermally insulated box, divided by a sealed partition into a technological compartment, containing a technological container, a tubular electric heater, gear and metering pumps, feed and discharge lines, as well as control tools and an instrument compartment containing., Control means . A disadvantage of the known dosing unit is that ne provides the operation of a dosing pump with a given dose of a chemical agent. An automated block installation is also known for the preparation and dosage of demulsifiers and corrosion inhibitors, and I also conduct a thermally insulated box divided by a sealed partition into a technological compartment containing a technological tank, a tubular electric heater, gear and metering pumps, control devices, a heater, a fan b. instrument compartment containing upraenilil means. The disadvantage of this installation is that the dosing pump does not achieve the required dosing accuracy, the filter is not perfect, the intake and discharge lines from the brass tubes of the connector Which are soldered, which reduce the reliability and durability during operation. The purpose of the utility model is to achieve a higher degree of metering accuracy, increasing reliability and durability.

Decree:. the goal is achieved that in the installation made in the form of a heat-insulated box, separated by a sealed partition into a technological compartment, containing the technological:, :: container with a level gauge, temperature gauges and electric heater, welded and metering pumps, and also discharge lines, npmrieH unit for dosing plunger with high precision dosing, a set of means for automatically stabilizing the feed with a hardness of not 1, a set of emergency stop means, at over pressure, external and internal signals protection, a filter element with increased throughput and elements of the line of penetration made of steel tubes with quick connectors.

In fig. The proposed installation of a dosage reagent is schematically shown. It contains a technological tank (I), equipped with a pointer (2) for visual control of the level of the KOCTV LCD, a pump-down automat (3); controlling the lower and upper limit levels, a manometric thermometer (4), controlling the temperature of the reagent heated by an electric heater (5). A filter (14) is mounted on the intake and discharge lines, ensuring uninterrupted operation of the plunger dosing unit (13). The gear pump (6) provides pumping and pumping: ie and mixing of the reagent. An anometer (15) is installed on the discharge line, signaling the extreme pressure values, with a high-pressure fan (12). The intake and discharge lines are made of steel tubes with quick couplings. . control (not shown in the figure) provides:

control of the process of filling the technological capacity and automatic deviation of the gear pump when filling the tank and the operation of the pumping machine;

mixing process control;

emergency shutdown of the pump when the level in the tank decreases: - below the minimum allowable and the machine trips, as well as when the pressure value in pump-1 exits the permissible limit;
