Abstract
The utility model discloses a kind of novel gas differential pressure type and add smelly system, comprise fuel gas pipeline and differential pressure type device for adding odor; Described fuel gas pipeline comprises fuel gas inlet and gas outlet, described gas pipeline is provided with combustion gas bye-pass; Smelly liquid is had in described differential pressure type device for adding odor; Described combustion gas bye-pass passes into the ullage of the smelly liquid of described differential pressure type device for adding odor; Described gas outlet is provided with smelly liquid bye-pass, and described smelly liquid bye-pass passes into below the liquid level of the smelly liquid of described differential pressure type device for adding odor; The section of described fuel gas pipeline between described combustion gas bye-pass and described smelly liquid bye-pass is provided with the pressure governor for reducing pressure.The beneficial effects of the utility model are: differential pressure type adds and smellyly instead of electric pump of the prior art and add smelly, improves operational security, decreases equipment expenditure.
Description
Technical field
The utility model relates to gas-fired equipment technical field, particularly relates to a kind of novel gas differential pressure type and adds smelly system.
Background technique
Traditional natural gas odorization adopts and adds smelly pump and microcomputer controller composition and add smelly and control system and come.This system needs scene to provide AC220V power supply, simultaneously because this system is used on fuel gas pipeline, requires that adding smelly pump is integrated explosion proof system form, and causing adding smelly operation danger increases, and equipment cost also remains high.
Model utility content
The purpose of this utility model is the technological deficiency for existing in prior art, and provides a kind of can completing without the need to power supply to add smelly novel gas differential pressure type and add smelly system.
The technological scheme adopted for realizing the purpose of this utility model is: a kind of novel gas differential pressure type adds smelly system, it is characterized in that comprising fuel gas pipeline and differential pressure type device for adding odor; Described fuel gas pipeline comprises fuel gas inlet and gas outlet, described gas pipeline is provided with combustion gas bye-pass; Smelly liquid is had in described differential pressure type device for adding odor; Described combustion gas bye-pass passes into the ullage of the smelly liquid of described differential pressure type device for adding odor; Described gas outlet is provided with smelly liquid bye-pass, and described smelly liquid bye-pass passes into below the liquid level of the smelly liquid of described differential pressure type device for adding odor; The section of described fuel gas pipeline between described combustion gas bye-pass and described smelly liquid bye-pass is provided with the pressure governor for reducing pressure.
Described gas pipeline is provided with the preposition pressure governor for reducing input gaseous-pressure at described fuel gas inlet place.
Working principle of the present utility model is: differential pressure type adds smelly system without the need to power supply, and utilization adds pressure difference before and after smelly pipeline and just can realize to the smelly liquid of automatic filling in fuel gas pipeline; This system requirements gaseous-pressure is not higher than the pressure that differential pressure type device for adding odor can bear, and the scene of being applicable to can not provide power supply, uses when not being strict with adding amount; When reality uses, the adjustment of smelly liquid adding amount just can be carried out by the valve of the valve and described smelly liquid bye-pass that control described combustion gas bye-pass.
The beneficial effects of the utility model are: differential pressure type adds and smellyly instead of electric pump of the prior art and add smelly, improves operational security, decreases equipment expenditure.
Accompanying drawing explanation
Figure 1 shows that differential pressure type adds the structural representation of smelly system.
Embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Embodiment:
Be illustrated in figure 1 a kind of novel gas differential pressure type and add smelly system, comprise fuel gas pipeline 1 and differential pressure type device for adding odor 5; Described fuel gas pipeline 1 comprises fuel gas inlet 11 and gas outlet 12.Described gas pipeline 1 is provided with combustion gas bye-pass 4; The front of combustion gas bye-pass 4 is provided with high pressure filter 2 and preposition pressure governor 3 successively, preposition pressure governor 3 for reducing input combustion gas pressure, in order to avoid differential pressure type device for adding odor 5 cannot bear gaseous-pressure and leak.
Described differential pressure type device for adding odor 5 is provided with seal chamber, has smelly liquid in cavity; Described combustion gas bye-pass 4 passes into the ullage of the smelly liquid of described differential pressure type device for adding odor 5; Described gas outlet 12 is provided with smelly liquid bye-pass 10, and described smelly liquid bye-pass 10 extension passes into below the liquid level of the smelly liquid of described differential pressure type device for adding odor 5; The section of described fuel gas pipeline 1 between described combustion gas bye-pass 4 and described smelly liquid bye-pass 10 is provided with the pressure governor 6 for reducing pressure.
During use, differential pressure type adds smelly system without the need to power supply, and utilization adds pressure difference before and after smelly pipeline and just can realize to the smelly liquid of automatic filling in fuel gas pipeline; This system requirements gaseous-pressure is not higher than the pressure that differential pressure type device for adding odor can bear, and the scene of being applicable to can not provide power supply, uses when not being strict with adding amount; When reality uses, the adjustment of smelly liquid adding amount just can be carried out by the valve of the valve and described smelly liquid bye-pass 10 that control described combustion gas bye-pass 4.
In addition, described gas pipeline 1 also needs mounting filter 7, pressure gauge 8 and butterfly valve 9 etc., and described smelly liquid bye-pass 10 is arranged between butterfly valve 9 and gas outlet 12.
The above is only preferred implementation of the present utility model; it should be noted that; for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
Claims (2)
1. novel gas differential pressure type adds a smelly system, it is characterized in that: comprise fuel gas pipeline and differential pressure type device for adding odor; Described fuel gas pipeline comprises fuel gas inlet and gas outlet, described gas pipeline is provided with combustion gas bye-pass; Smelly liquid is had in described differential pressure type device for adding odor; Described combustion gas bye-pass passes into the ullage of the smelly liquid of described differential pressure type device for adding odor; Described gas outlet is provided with smelly liquid bye-pass, and described smelly liquid bye-pass passes into below the liquid level of the smelly liquid of described differential pressure type device for adding odor; The section of described fuel gas pipeline between described combustion gas bye-pass and described smelly liquid bye-pass is provided with the pressure governor for reducing pressure.
2. a kind of novel gas differential pressure type according to claim 1 adds smelly system, it is characterized in that described gas pipeline is provided with the preposition pressure governor for reducing input gaseous-pressure at described fuel gas inlet place.
