Abstract
The utility model relates to a humidity alarm filter matched with a detection gas adjusting system. The humidity alarm filter is composed of a filter core and a humidity detector, wherein the filter core is composed of a base, a filtering core mounted on the base, and a filter cover body sleeved on the outside of the filter core, the base is provided with a gas inlet, a gas outlet and an electrodedetection inlet, the gas inlet is communicated with the electrode detection inlet, the gas inlet is communicated with the gas outlet via the filter core and a cavity formed by the filter cover body,and the humidity detector is mounted at the bottom of the filter cover body. The filter not only is suitable for detecting an sampling gas with high temperature, high humidity and high content of particles in an on-line monitoring system, but also effectively ensures the accuracy of the measurement data in the on-line monitoring system, greatly improves the stability and the reliability of the on-line monitoring system operation, and reduces the failure rate of the whole system and prolongs the service life thereof.
Description
Technical field
The utility model relates to a kind of and detects the matching used humidity alarm filter of gas regulating system device.
Background technology
Along with the fast development of industrial economy, make air pollution problems inherent serious day by day, air pollution has become the major issue of whole society's common concern.Along with the improving constantly of people's environmental consciousness, more and more pay attention in recent years for content of harmful in the air and control thereof.Thereby to have high-intelligentization, high stability, high-precision on-line monitoring instrument be the basis of detecting harmful substance in the air.But that uses at present is emitted on line monitoring system to various pollution sources, and can not carry out accurately reliable and stable detection on-line monitoring to the gas of high temperature, high humidity, high particle content.Its main cause is that the equipped filter filter effect of this kind equipment is not good.Because its filter poor filtration effect, cause equipment pipeline or gauge internal accumulated particulate matter easily, cause test data that deviation or inaccurate is arranged, when filter core need be changed, because filter housing is a metal structure, can't see the dirty degree of filter core, usually incurs loss through delay filter core and change the time, or cause the maintenance personal need regularly carry out dismounting and check whether filter core needs to change waste of manpower.Be ceramic element owing to its material for core simultaneously, the crisp generation fragmentation in replacing or transportation easily of its quality.
Summary of the invention
The utility model purpose is at the deficiencies in the prior art, provide a kind of can reliable separation the humidity alarm filter device of superfine solid particle and steam condensation in the sampling gas.
The utility model purpose is achieved in that this humidity alarm filter device is to constitute by crossing filter core and moisture detector, the described filter core of crossing is made up of support and the filter core cover body that is assemblied in the filter core on the support and is sleeved on the filter core outside, be respectively equipped with inlet, outlet and detecting electrode inlet on the support, air inlet is communicated with the detecting electrode inlet, and chamber, filter core that air inlet surrounds via filter core cover body and filter core are communicated with the gas outlet; Described moisture detector is assemblied in the bottom of filter core cover body.
The technological progress that the utility model is obtained: the superfine efficient filter core that this filter element adopts the titanium alloy powder synthesize ceramic to make, can not only be effectively contained solid in the discrete sampling device reliably, especially superfine solid particle, also have effect, prevented that effectively aqueous vapor from entering in the analytical instrument the aqueous vapor condensation in the sampling gas.Condensed water will be detected by moisture detector simultaneously, can report to the police or close the sampling air pump.Therefore this filter not only is useful in the detection of line monitoring system to high temperature, high humidity, high particle content sample gas, also can effectively guarantee the accuracy of on-line monitoring system measurement data, also can improve stable, the unfailing performance of on-line monitoring system work greatly, reduce the fault rate of total system and prolong its service life.This filter adopts transparent filter core cover body, and the pollution level in its filter core can observe directly from the outside, conveniently in time to change or to clean filter core, has further guaranteed the operation that gas analysis system is reliable and stable.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present utility model.
The specific embodiment
Be that embodiment further specifies the utility model below with the accompanying drawing, as shown in Figure 1, this humidity alarm filter device constitutes by crossing filter core and moisture detector, the described filter core of crossing is made up of support 1 and the filter core cover body 1 that is assemblied in the filter core 6 on the support 1 and is sleeved on filter core 6 outsides, be respectively equipped with inlet, outlet 2,5 and detecting electrode inlet 3 on the support 4, air inlet 2 is communicated with detecting electrode inlet 3, and the chamber that air inlet 2 surrounds via filter core cover body 1 and filter core 6, filter core 6 are communicated with gas outlet 5; Described moisture detector the utility model is selected humidity sensor 7 for use, and this humidity sensor 7 is assemblied in the bottom of filter core cover body 1, and the output of its humidity sensor 7 is connected to alarm and control sampling pump system respectively.Filter core cover body 1 selects for use transparent material to make, and observes the pollution level that is assemblied in the filter core 6 in the filter core cover body 1 with convenient, so that in time cleaning or more renew cartridge 6.For making things convenient for this filter and the supporting use of monitoring system, present embodiment also is provided with the frame that is linked and packed on support 4.
During the supporting use of this filter and gas monitoring system, its sampling gas is at first entered by air inlet 2 in the chamber that is surrounded by filter core cover body 1 and filter core 6, exports gas outlet 5 to through behind the filter core then.When if the water content in the sampling gas is higher, flow velocity slowed down when gas was by filter core 6 owing to sample, aqueous vapor condensation in the sampling gas forms aqueous water, its aqueous water will flow to the bottom of filter core cover body 1 along the inwall of filter core cover body 1, this moment, humidity sensor 7 promptly sent the humidity alarm signal, and this signal is delivered to alarm, alarm and preset value compare two groups of switching signals of back output, the one road is used for reporting to the police, the sampling pump that another road is used for controlling gas monitoring system quits work, and flows through thereby will no longer include gas in the gas circuit, and aqueous vapor is condensation no longer, the back alarm returns to normal to treat to recover humidity normally, and sampling pump restarts.
