Abstract
The utility model belongs to the field of kiln bubbling systems, and particularly relates to a gas source supply of a glass kiln bubbling system. The bubbling gas supplying system of the kiln comprises three paths of respectively a nitrogen making machine pipeline, a nitrogen cylinder pipeline, and a compressed air pipeline, wherein each branch pipeline is provided with a pressure reducing valve group, and a check valve. Three paths of gases are collected in a main pipe, and one group of precise filters is arranged. According to the bubbling gas supplying system, gas can be supplied by virtue of three paths of gas sources, high-purity nitrogen is used as a bubbling main source, and a buffer tank is arranged, so that the cleanness of a gas source of the bubbling gas supplying system is maximally ensured. Compressed air and the nitrogen cylinder are used as standby gas sources, and are in a heat standby state under a normal condition, and when a certain path of gas source fails, automatic switching can be realized, the time delay caused by manual operation is reduced, and the safety and stability of the bubbling system are ensured.
Description
Technical field
The utility model relates to kiln bubble systems, is mainly used in glass furnace bubbling source of the gas and supplies with.
Background technology
It is source of the gas that existing kiln bubble systems adopts pressurized air, because pressurized air contains moisture, and oily and mechanical residue etc., bubbling pipe long-time contact with it under hot conditions can produce certain corrosion and scale formation, affects normal use and the life-span of bubbling pipe.
Utility model content
The technical problems to be solved in the utility model is: provide a kind of safety, stable, clean bubbling source of the gas.Prevent bubbling pipe corrosion and fouling.
The utility model for the technical scheme that its technical problem of solution adopts is: adopt the main source of the gas of high-purity nitrogen as kiln bubbling.And adopt pressurized air and nitrogengas cylinder as origin for subsequent use, thereby ensure the safety and stability of bubble systems.
Concrete scheme is that airing system is divided into three tunnels, is respectively Nitrogen plant pipeline, nitrogengas cylinder pipeline and pneumatic line, after Zhe San road airing system gathers, enters bubbling housing.
On the airing system of described San road, be provided with pressure loading valve group and vacuum breaker.
After gathering, three road airing systems enter bubbling housing through strainer.
This airing system can be realized three channel gas source air feed.Different reference pressure values is set to respectively Nitrogen plant pipeline reducing valve, pneumatic line reducing valve, nitrogengas cylinder pipeline reducing valve according to order from high to low.When pressure after the pressure in certain supply air line is higher than vacuum breaker, the gas in this pipeline arrives after vacuum breaker, enters bubbling housing, realizes air feed.After higher level's pipeline breaks down, in its pipeline, gaseous tension reduces suddenly, causes the pressure after vacuum breaker to be less than supply gas pressure, now automatically switches to the pipeline that gaseous tension is higher and realizes air feed.Therefore, the air feed of three channel gas source order is Nitrogen plant pipeline, pneumatic line, nitrogengas cylinder pipeline.
The beneficial effects of the utility model are:
Can realize three channel gas source air feed, high-purity nitrogen is as the main source of the gas of bubbling, and surge tank is set as strainer, ensures to greatest extent the cleaning of bubbling airing system source of the gas.Pressurized air, nitrogengas cylinder, as bailout gas, under normal circumstances, in hot standby state, can be realized automatic switchover after Dang Mou road source of the gas breaks down, and reduce the time lag that manual operation brings.Ensure security and the stability of bubble systems.
Brief description of the drawings
Fig. 1: the utility model structural representation;
In figure: 1, Nitrogen plant pipeline; 2, nitrogengas cylinder pipeline; 3, pneumatic line; 4, pressure loading valve group; 5, vacuum breaker; 6, strainer; 7, bubbling housing; 8, bubbling supply air line; 9, valve.
Specific embodiment:
Bubbling airing system Gong San road, is respectively Nitrogen plant pipeline 1, nitrogengas cylinder pipeline 2, pneumatic line 3.Above-mentioned pepeline fittings as shown in Figure 1, all arranges pressure loading valve group 4, vacuum breaker 5 on each pipeline.Then three road gas collections enter bubbling housing 8 to a set filter 6 being set after house steward.
Principle of work:
In normal productive process, Tu Zhong tri-road gas pipings be Nitrogen plant pipeline 1, nitrogengas cylinder pipeline 2, pneumatic line 3 and pressure loading valve group 4, vacuum breaker 5 all in opened condition, the valve of existing bubbling supply air line 8 is in closing condition.
Suppose: Nitrogen plant pipeline reducing valve reference pressure is set as 0.5MPa; Pneumatic line reducing valve reference pressure is set as 0.4MPa; It is reference settings pressure that nitrogengas cylinder pipeline reducing valve reference pressure is set as setting pressure above 0.3MPa(, can set voluntarily according to actual service condition, and between Dan San road, pressure difference had better not be lower than 0.05MPa).
Under normal circumstances, Nitrogen plant pressure is the highest, pneumatic line secondly, nitrogengas cylinder pipeline is minimum, three road gas collections are after house steward, gaseous tension in Nitrogen plant pipeline is higher than the supply gas pressure of pneumatic line, nitrogengas cylinder pipeline, the supply gas pressure of Nitrogen plant pipeline is greater than the supply gas pressure of pneumatic line, nitrogengas cylinder pipeline, only has like this gas in a road Nitrogen plant pipeline to enter bubbling housing.
If Nitrogen plant pipeline causes after shutdown because of unknown cause, the pressure in Nitrogen plant pipeline reduces suddenly, and the supply gas pressure maximum of pneumatic line, oppresses other two-way, only has the gas in a road pneumatic line to enter bubbling housing.
In the time that Nitrogen plant pipeline, pneumatic line cannot air feed, the gaseous tension of nitrogengas cylinder pipeline is the highest, so just only has the gas in nitrogengas cylinder pipeline to enter bubbling housing.
When causing three road gas pipings, damages unknown cause, while being unable to supply gas, and can be by the valve of existing bubbling supply air line 9 manual unlocking supply pressurized air.
