LPG Vaporizers Dages (Russia)

The advantages of LPG Vaporizers Dages (Russia)

In the case where consumption of the vapor phase of the liquefied gas exceeds the speed of natural evaporation in the vessel requires the use of vaporizers, which are due to electric heating can accelerate vaporization of the liquid phase in the steam and ensure the flow of gas to the consumer in the calculated volume.

The purpose of the LPG vaporizer is the conversion of the liquid phase liquefied petroleum gas (LPG) in the vapor occurring due to the use of evaporators with electric heating. The evaporator unit can be equipped with one, two, three or more electric vaporizers.

Installation of evaporators enables to work as one evaporator or more in parallel. Thus, the plant capacity may vary depending on the number of concurrent evaporators.

The principle of operation of the evaporator unit:

When you turn on the evaporator unit, the automation heats of evaporation installation of up to 55C. The solenoid valve at the inlet of the liquid phase in the evaporating installation will be closed until until the temperature reaches to these parameters. The level sensor shut off (in the case of gauge shut off) controls the level and the overflow valve closes at the entrance.

The vaporizer begins to heat. Upon reaching 55°C will be open the magnetic flap at the entrance. LPG enters into the heated tube case, and evaporates. At this time, the vaporizer continues to heat up, and upon reaching the core temperature of 70-75°C spiral heating will be disabled.

The evaporation process continues. - Evaporator gradually cools and when the temperature drops to 65°C spiral heating will be enabled again. The cycle is repeated.

Equipment the evaporator unit:

Evaporator can be equipped with one or two regulatory groups, to duplicate system reduction, and bypass line vapor phase, passing the evaporative system for the use of the vapor phase of natural evaporation in the tanks.

Pressure regulators are used to set the predetermined pressure at the outlet of the evaporator unit to the consumer.

1st stage — adjustment medium pressure (16 to 1.5 bar).
2nd step — adjust the low pressure from 1.5 bar to a pressure needed when applying to the consumer (such as gas boiler or gas-piston power plant).

The advantages of evaporators PP-TEC

When designing the evaporator unit is always necessary to consider three components:

1. To provide the specified performance,
2. To create the necessary protection from hypothermia and overheating of the core of the evaporator.
3. To correctly calculate the geometry of the coolant to the conductor of the gas in the evaporator

The performance of the evaporator depends not only on the amount of voltage from the network. Another important factor is the geometry.

Correctly calculated the location provides efficient use of mirror heat transfer and consequently increasing the efficiency of the evaporator.
In evaporators Dages (Russia), by correct calculations, the company's engineers have increased this ratio up to 98%.

The evaporator unit of the company Dages (Russia) losing only two percent of heat. The remainder is used for evaporation of the gas.

Almost all European and American manufacturers LPG evaporation equipment mistakenly interpret the term "redundant protection" (the condition for realization of the duplication of protection from overheating and overcooling).

The concept of "redundant protection" implies the implementation of a "safety net" of individual work units or entire equipment completely, by the use of redundant elements from different manufacturers and with different principles of action. Only in this case it is possible to minimize the possibility of equipment failure.

Many manufacturers are trying to implement this feature (with protection from hypothermia and falling liquid fraction of LPG to the consumer), setting the input supply line, two solenoid valve, connected in series, the same manufacturer. Or use two consistently included in the network of temperature sensor on/opening of valves.

Imagine the following situation. One magnetic valve stuck in open state. How can You determine what valve failed? NO way! The installation will continue to work, losing the opportunity in time to ensure the safety of the operation under hypothermia in the event of failure of the second valve.

In LPG evaporators Dages this feature was implemented in a completely different way.

In evaporative applications, the company Dages (Russia) use the algorithm aggregate of the three elements of protection from hypothermia:

1. Electronic device
2. Magnetic flap 
3. Mechanical shut off valve shut off.

All three elements have completely different principle that allows to speak with confidence about the impossibility of the occurrence of a situation in which no vaporized gas in liquid form will get into the pipeline of a consumer.

In LPG vaporization installations of the company Dages (Russia) was applied the same in the implementation of the protection of the evaporator from overheating. The elements involved as electronics and mechanics.

Company Dages (Russia) for the first time in the world was realized the function of integration of subsurface liquid into the cavity of the evaporator with the possibility of constant heated blade.

No manufacturer of evaporation equipment does not use this own designed function. Using a heated cutter, the evaporator unit Dages (Russia), received the possibility of evaporation of the heavy components of LPG.

Many manufacturers copying each other, set the clipper on the output to regulators. Contained in the gas mercaptans, sulphur and heavy gases having a very high density, getting into a cold pipeline, congenerous and deposited on the tube walls, razor, and regulators, which significantly reduces the service life of the equipment.

In evaporators Dages (Russia) heavy precipitation in the molten state, kept shut off until you remove them through the waste ball valve in the evaporator installation.

Cutting mercaptans, the company Dages (Russia) was able to increase the service life of installations and regulatory groups at times. So, to take care of operating expenses not requiring regular replacement of membrane regulators, or their complete expensive replacement, leading to downtime of the evaporator unit.

And realize the function of heating the solenoid valve and filter at the inlet to the evaporator installation does not allow accumulated water in them and freezing in the solenoid valve to disable when triggered. Either to restrict entry of the liquid phase in the evaporator installation.

The evaporator unit of the Russian company Dages is a reliable and stable work during the long years of operation.
