Carbon dioxide busbar warm air heating system

Technical Field

The utility model relates to a heating field specifically is a carbon dioxide busbar warm braw heating system.

Background

When the hydrogen system of two generators in the Hongshan thermal power plant replaces hydrogen or air in the generators by using carbon dioxide as an intermediate medium, the liquid carbon dioxide expands from a compressed gas cylinder to a carbon dioxide busbar and absorbs a large amount of heat from the gas expansion, so that the busbar pipeline is frozen and blocked; in addition, if a special drainage system is not arranged, water directly flows to the ground after being sprayed, and civilized production is influenced; because the manometer behind the pressure reducing valve is covered by the sprayed water flow, the observation of the manometer by a field replacement person is unclear, and whether the gas cylinder is empty or not is difficult to judge; on-site replacement personnel are always wetted by water or frosted gas cylinder connectors are frostbitten when replacing gas cylinders, and the working environment is poor.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a carbon dioxide busbar warm braw heating system to solve the problem among the prior art, adjust the warm braw temperature in the switch board on the spot according to ambient temperature and busbar heat absorption condition, with do not take place that the pipe-line equipment frosts or freezes as the standard, thereby improve the interior gas replacement speed of generator.

In order to achieve the above object, the utility model provides a following technical scheme:

a carbon dioxide busbar warm air heating system comprises a CO2 heating device, a warm air heating fan set 4, a carbon dioxide busbar 3, a CO2 air inlet 2 and a CO2 air bottle 1, wherein the CO2 air bottle 1 conveys CO2 to the carbon dioxide busbar 3 through the CO2 air inlet 2, the carbon dioxide busbar 3 and related pipelines are heated by hot air blown out of the external warm air heating fan set 4, the warm air heating fan set 4 heats CO2 in the carbon dioxide busbar 3, and the carbon dioxide busbar 3 conveys the heated CO2 to a CO2 heating device.

Furthermore, each CO2 gas cylinder 1 is connected with a CO2 gas port 2 through a safety valve 5, the CO2 gas ports 2 all converge into a pressure reducing valve I10 through a gas pipe I6, a stop valve I7 is arranged on the gas pipe I6, the gas pipe I6 is communicated with a gas pipe II 8, and a pressure reducer inlet 9, the pressure reducing valve I10, a pressure reducing valve II 11 and a pressure reducer outlet 12 are sequentially arranged on the gas pipe II 8.

Further, the warm air heating fan unit 4 comprises a filter 13, a warm air fan 15, a silencer I14, a silencer II 16, an air heater 17 and a stop valve IV 18, the filter 13, the silencer I14, the warm air fan 15, an effector 16, the air heater 17 and the stop valve IV 18 are sequentially arranged in an air pipe III 21, and the air pipe III 21 is externally arranged on the carbon dioxide busbar 3.

Further, the air pipe II 8 is communicated with an air pipe IV 23, a heating device entrance 22 is arranged on the air pipe IV 23, and the air pipe IV 23 conveys heated CO2 gas to a CO2 heating device.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-2, in the embodiment of the present invention,

In fig. 2, 19, 20 and 24 are manual valves for controlling the heating air volume.

In operation, an operator needs to replace gas on site to start the warm air heating system in the local control cabinet during gas replacement, and the set temperature range is adjusted by the gas cylinder according to the carbon dioxide busbar and the related pipeline; for each part needing to be heated, the heating air quantity can be adjusted by only opening and closing or adjusting the valve opening on each pipeline, so that the pipeline and equipment can be heated, and the situation that the working of operators is influenced by the fact that the site environment is stuffy is avoided.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention.
