Abstract
The utility model discloses a filtering device used in a sampling device, which comprises an organic glass tank and a filter unit, wherein the filter unit is arranged in the inner cavity of the organic glass tank, the organic glass tank and the filter unit constitute a sandwich structure, a tank cover is arranged above the sandwich structure, and the bottom of the organic glass tank is provided with a sewage outlet. The filtering device disclosed by the utility model can effectively filter sampling gas; and the filtering device is simple in structure, safe in use, and convenient to install. According to the utility model, purer gas can be obtained in comparison with other filter units, the damage rate of core parts of analysis instruments is reduced, and the measurement precision is greatly improved.
Description
Technical field
The utility model relates to a kind of filter, particularly relates to a kind of device that test sample gas filters that is fit to treat.
Background technology
At present, along with socioeconomic development, in the production process of the large size industrial enterprise of the industries such as colliery, oil, air separation, the gas that needs under some production link production process is produced is (such as CO, CO
2, O
2Deng gas) carry out necessary concentration detection, to safeguard normal activity in production.In testing process, at first must sample to tested gas, and sampling just needs to use corresponding sampling device and pretreatment unit.At present, most preliminary treatment device does not adopt carborundum as pretreatment element, there is not non-hydrophilic characteristics yet, cause in the treated sample gas still with a large amount of moisture, cause final detection result inaccurate, in the time of the normal production of impact, also strengthen employee's maintenance, thereby caused unnecessary cost waste.
The utility model content
The utility model is the shortcoming that exists in order to overcome the traditional filtering device, provide a kind of can be effectively to sample gas filter, simple in structure, use safety, filter easy for installation.
The purpose of this utility model realizes by following technical proposals.
A kind of filter plant for sampler, comprise organic glass jar body, and be arranged on filter in the lucite tank inner chamber, described lucite tank body and filter consist of sandwich, be provided with cover above this sandwich, the bottom of described lucite tank body is provided with sewage draining exit.
Further, in the described equipment:
Be provided with air inlet, gas outlet and back blow port on the described cover, described cover middle part is provided with inlet channel, outlet passageway and the blowback passage that is made of seal, and described air inlet, gas outlet and back blow port are corresponding with this inlet channel, outlet passageway and blowback passage.
Described inlet channel is connected with the interlayer cavity, and blowback passage and outlet passageway are connected with the cavity that filter consists of.
The described filter of the inner chamber of lucite tank body that places is taked silicon carbide material, and the filter sidewall is made of ceramic supporting body and the ceramic fibre composite filtering film two parts that are attached to this supporter inwall.
The utility model is a kind of filter that can place sampling device under the adverse circumstances such as high temperature, high pressure, corrosive gas, irritative gas and high dust concentration.It can obtain the gas purer than other filters, has reduced the spoilage of analytical instrument core component, has greatly improved the precision of measuring.
The utility model adopts carborundum as the device that filters, it is little by the aperture, ceramic fibre composite filtering film two parts of high strength, highly-breathable ceramic supporting body and high filtering precision form, and has the advantages such as good gas permeability, heat endurance, mechanical strength are high, acid-alkali-corrosive-resisting, non-hydrophily.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further details.
As shown in Figure 1, a kind of filter plant for sampler, comprise organic glass jar body 1, and be arranged on filter 2 in lucite tank body 1 inner chamber, wherein: lucite tank body 1 consists of sandwich with filter 2, be provided with cover above this sandwich, the bottom of described lucite tank body 1 is provided with sewage draining exit 7 and blowoff valve 6.Be provided with air inlet 5, gas outlet 3 and back blow port 4 on the cover, the cover middle part is provided with inlet channel, outlet passageway and the blowback passage that is made of seal, and air inlet 5, gas outlet 3 and back blow port 4 are corresponding with this inlet channel, outlet passageway and blowback passage; Air inlet is sensible to be connected with the interlayer cavity, and blowback passage and outlet passageway are connected with the cavity that filter 2 consists of.
The described filter 2 of the inner chamber of lucite tank body 1 that places is taked silicon carbide material, and filter 2 sidewalls are made of ceramic supporting body and the ceramic fibre composite filtering film two parts that are attached to this supporter inwall.
During work, the sampler of the front end that sample gas passes through enters air inlet 5, then enters in the lucite tank body 1, and the test sample gas for the treatment of that enters in the lucite tank body 1 enters outlet passageway by filter device 2, then 3 enters back-end device from the gas outlet.The filter 2 of silicon carbide material can effectively filter moisture excessive in the sample gas, tar and graininess impurity; When these impurity are attached to carborundum filter 2 surperficial, can utilize back blow port 4 to pass into the gas of an amount of pressure, all foreign material are blown clean, foreign material can drop to the bottom of lucite tank body 1, then utilize blowoff valve that the dirt of calmness is drained only.
The above; only be embodiment of the present utility model; be not that the utility model is done any restriction, every any simple modification, change and equivalent structure of above embodiment being done according to the utility model technology changes, and all still belongs in the protection domain of technical solutions of the utility model.
