Description
Technical field
The utility model relates to a kind of filters dusty.
Background technique
Dust filter unit is the commonly used equipment of sundries in filtering dust, generally separates bulk foreign matter by strainer, prevents
Systematic sampling line clogging is monitored, makes monitored industrial smoke that can not carry out continuous online prison in the instrument in normal system
Survey, influence the monitoring to produced on-site industry, existing dust filter unit often because the industrial smoke of the concentration dusty of work without
Method effectively filters, and causes the gas sampling probe of monitoring system is obstructed perhaps to block or do not meet instrument testing requirements
Dust particles enter instrument, generate pollution to instrument gas chamber, lead to the monitoring data inaccuracy of system, thus can not be promptly and accurately
Discovery site technique safety in production hidden danger or monitoring data inaccuracy, finally industrial tail gas not up to standard is discharged into greatly
In gas, environmental pollution is caused.
Utility model content
In view of the problems of the existing technology, the utility model proposes a kind of filters dusty.
The utility model solves the technical solution of the above technical problem: providing a kind of filter dusty, including cavity, group
Filter and heater are closed, in the cavity, the heater is arranged on the outside of the cavity for the combination filter setting,
The combination filter includes a lot of dust filter and thin-walled filter, and a lot of dust filter is fixed by welding in cavity
The outlet side in portion in the cavity, and a lot of dust filter and thin-walled is arranged in internal inlet end, the thin-walled filter
There are gaps between filter, and circlip is provided in gap, and inlet suction port, the air inlet is arranged in the cavity inlet end
Connector is fixed in the through-hole at one middle part of ring flange of cavity inlet end setting by sealing element, is arranged in the cavity outlet side
There is bellows, which passes through the through-hole and thin-walled filter outlet mouth spiral shell at two middle part of cavity outlet side setting ring flange
Line connection, the other end are arranged in the mounting flange on ring flange two.
The technical solution that the utility model further limits are as follows:
Above-mentioned further includes temperature controller, and temperature controller is connected by high temperature wire with heater.
It is above-mentioned that heat-preservation cotton is provided on the outside of heater.
It is above-mentioned that dust-proof insulating outer cover is provided on the outside of heat-preservation cotton.
Cavity air inlet and outlet end above-mentioned is respectively arranged with filter holder, and the filter holder is in the same horizontal position.
The utility model has the beneficial effects that the utility model uses double-filtration, and sampling probe is cooperated to use, finally
Achieve the effect that multistage filtering, by first level filtering device a lot of dust filter of interior forward end, which takes flexible mistake
Filtration principle can be realized volume filtration dusty, will carry out second level mistake by thin-walled filter again after a large amount of dust-filtering
Filter, after filtering, by blowback scavenging, being stayed in the intracorporal dust blowback to process pipe of filter chamber after filtering, from
And ensure to meet by the filtered industrial smoke of filter dusty the subsequent equipment use demand of monitoring system, lead to simultaneously
The measures such as setting heater and heat-preservation cotton are crossed, so that filter cavity keeps relatively dry, to make the work containing dust and steam
Industry flue gas is not easy to harden with filter surfaces in the cavity, while being shaken by the mechanical energy of filter itself, can will be a small amount of
Hardened dust vibration is broken, and filtered dust can be discharged by blowback scavenging, realizes filter self-purification function, reaches
To filtering high concentrate dust flue gas effect, prolong the service life.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
Embodiment 1
The present embodiment provides a kind of filter dusty, structure is as shown in Figure 1, include cavity 1, combination filter, temperature control
Device 2 and heater 3, cavity are fixed on the respectively arranged filter holder 4 of air inlet and outlet end the same horizontal position, combination filter
In the cavity, the setting of heater 3 is provided with heat-preservation cotton 5 in 1 outside of cavity on the outside of heater 3 for setting, in 5 outside of heat-preservation cotton
It is provided with dust-proof insulating outer cover 6, temperature controller 2 is connected by high temperature wire with heater 3, and combination filter includes a lot of dust mistake
Filter 7 and thin-walled filter 8, a lot of dust filter are fixed by welding in the inlet end of inside cavity, the setting of thin-walled filter
The outlet side in portion in the cavity, and there are gaps between a lot of dust filter and thin-walled filter, and bullet is provided in gap
Property retaining ring 9, cavity inlet end be arranged inlet suction port 10, the inlet suction port by sealing element be fixed on cavity inlet end setting
The middle part of ring flange 1 through-hole in, 1 outlet side of cavity is provided with bellows 12, which passes through cavity outlet
The through-hole at 2 13 middle part of end setting ring flange is threadedly coupled with thin-walled filter outlet mouth, and the other end is arranged on ring flange two
In mounting flange.
The present embodiment uses double-filtration, and sampling probe is cooperated to use, and is finally reached the effect of multistage filtering, passes through
First level filtering device a lot of dust filter of interior forward end, the filter are taken flexible filter principle, be can be realized dusty
Volume filtration will carry out secondary filtration by thin-walled filter again after a large amount of dust-filtering, after filtering, be swept by blowback
Gas, being stayed in the intracorporal dust blowback to process pipe of filter chamber after filtering, so that it is guaranteed that by the filter dusty
Filtered industrial smoke meets the subsequent equipment use demand of monitoring system, while being arranged by the way that heater and heat-preservation cotton etc. is arranged
Apply so that filter cavity keep relatively dry, thus make the industrial smoke containing dust and steam in the cavity with filter table
Face is not easy to harden, while being shaken by the mechanical energy of filter itself, can shake a small amount of hardened dust and be crushed, and can
Filtered dust is discharged by blowback scavenging, realizes filter self-purification function, reaches filtering high concentrate dust flue gas effect,
Prolong the service life.
In addition to the implementation, the utility model can also have other embodiments, all to use equivalent replacement or equivalent change
The technical solution to be formed is changed, the protection scope of the requires of the utility model is all fallen within.
