This water gas preliminary treatment analytic system need not the water pump as the power supply, guarantees the gas tightness of preliminary treatment pipeline more easily.
Description
Technical field
This utility model relates to gas analysis technology field, especially a kind of water gas Preprocessing system.
Background technology
Gas Preprocessing system, is a system being analyzed the composition of sample gas, is limited to the environmental factors of each occasion, makes the sample gas collected generally with granular material, therefore also needed its pretreatment before analyzing sample gas components.
Pretreatment herein include washing, except the operation such as water and filtration, wherein, by water washing tank can by sample gas particulate matter remove, but due to washing step, necessarily insert steam to sample gas, therefore used condenser to remove steam in sample gas, filtered by filter the most again.
With reference to Fig. 1, the equipment that above operation relates to includes the pretreatment pipeline being at least made up of water washing tank, condenser and filter, and is positioned at the air pump on pretreatment pipeline；Wherein, for providing the motive power of pretreatment pipeline, air pump is placed on water washing tank, condenser and filter.
When above pretreatment system is for water gas, owing to needing the Control for Oxygen Content in water gas 0.2%～0.3%, and the oxygen content in air is 26% so that the air-tightness of pretreatment system is had higher requirement.And air pump is placed on water washing tank, condenser and filter so that pretreatment pipeline exports negative pressure state all the time, it is difficult to ensure hermetic seal.
Utility model content
The deficiency existed for prior art, the purpose of this utility model is to provide a kind of water gas Preprocessing system, it is not necessary to water pump is as power source, it is easier to ensure the air-tightness of pretreatment pipeline.
For achieving the above object, this utility model provides following technical scheme: a kind of water gas Preprocessing system, including being in turn connected to form the water scrubber of pretreatment pipeline, condenser and filter, described water scrubber has inner chamber, the air inlet pipeline of communication with cavity and outlet pipe, described air inlet pipeline be placed on inner chamber one section is provided with water inlet and air inlet, and described water scrubber also has the discharge pipe line with inner space.
By using technique scheme, when water enters into air inlet pipeline from water inlet, making air inlet side produce negative pressure, thus sample gas is brought into air inlet pipeline, whole process is without air pump.
This utility model is further arranged to: described air inlet is placed on water inlet.
By using technique scheme, in a upper operation, it is passed through water, the sample gas being passed through can be brought in air inlet pipeline more up hill and dale in next operation.
This utility model is further arranged to: be additionally provided with desulfurizer on described pretreatment pipeline, and described desulfurizer is placed on filter.
By using technique scheme, use desulfurizer, other gases in addition to gas to be detected in sample gas can be filtered off.
This utility model is further arranged to: be additionally provided with membrane filter on described pretreatment pipeline, and described membrane filter is placed on desulfurizer.
By using technique scheme, use membrane filter, the sample gas obtained can be made purer, improve the analysis precision of subsequent processing.
Accompanying drawing explanation
Fig. 1 is the flow chart of pretreatment system in prior art；
Fig. 2 is the flow chart of pretreatment system in the present embodiment；
Fig. 3 is the sectional view of water scrubber in Fig. 2.
Detailed description of the invention
With reference to Fig. 2 to Fig. 3, embodiment of the present utility model is described further.
With reference to Fig. 2, the water gas Preprocessing system in the present embodiment, including pretreatment pipeline, the process flow path of this pretreatment pipeline is sequentially provided with water scrubber 1, condenser, filter, desulfurizer and membrane filter.
So arranging, water gas Preprocessing system works as follows: sample gas first passes through water scrubber 1 and washes, and can wash away the solid sundries in sample gas；Condensation vapor therein is become water droplet by condenser by sample gas through washing again, makes sample gas be dried；Sample gas through condenser passes through filter again to filter off water droplet；Through filter sample gas again through desulfurizer with improve sample gas purity, thus improve subsequent processing analyze precision；Eventually pass membrane filter, owing to membrane filter has good strainability, therefore sample gas can be filtered up hill and dale, improve the purity of sample gas further, improve the precision that sample gas is analyzed.
With reference to Fig. 3, the water scrubber 1 in the present embodiment has inner chamber, air inlet pipeline and an outlet pipe, and wherein, air inlet pipeline and outlet pipe are all and inner space.Sample gas is passed into by air inlet pipeline the inner chamber being mounted with water, discharges from outlet pipe after cleaning, thus obtain the cleanest sample gas.
Wherein, air inlet pipeline has and is built in one section of inner chamber and be placed on one section of inner chamber, and one section that is placed on inner chamber is provided with water inlet and air inlet, and water scrubber 1 also has the discharge pipe line with inner space.Sample gas and water enter into inner chamber by air inlet and water inlet respectively, and sample gas is washed by water, and finally, water is discharged from discharge pipe line, and sample gas is discharged from outlet pipe.
So arrange, following two advantage can be brought: one, water supplements in real time, in the case of ensureing to have abundant water resources, the clean result of sample gas can be improved；Two, when water enters into air inlet pipeline from water inlet, making air inlet side produce negative pressure, thus sample gas is brought into air inlet pipeline, whole process, without air pump, is therefore easier to keep the air-tightness of pretreatment pipeline.
With reference to Fig. 3, on air inlet pipeline path direction, air inlet is placed on water inlet.So arrange, in a upper operation, be passed through water, the sample gas being passed through can be brought in air inlet pipeline more up hill and dale in next operation.
The above is only preferred implementation of the present utility model, and protection domain of the present utility model is not limited merely to above-described embodiment, and all technical schemes belonged under this utility model thinking belong to protection domain of the present utility model.It should be pointed out that, for those skilled in the art, without departing from the some improvements and modifications under this utility model principle premise, these improvements and modifications also should be regarded as protection domain of the present utility model.
