Description
Technical field
This utility model relates to emission measurement instrument accessory field, particularly relates to a kind of smokemeter heater。
Background technology
At present, specifying according to environmental administration, electric field, steel mill, cement plant, chemical plant etc. manufacture the enterprise of gaseous contaminant, it is necessary to install smokemeter at gaseous contaminant floss hole, are used for the visible particle thing in real-time monitoring waste gas。
But, existing smokemeter has one disadvantage in that when monitoring in real time, it is simply that climate impact is bigger。Such as in the area that the north is cold, when the temperature is low, after the steam in the waste gas given off and monitoring probe contacts, icing phenomenon can be there is inside detection probe, had a strong impact on measurement result。
For solving this problem, it is necessary to detection probe is heated above freezing。Now conventional way is usually at the whole flue dust additional lagging casing of probe, detection probe is incubated, but lagging casing volume is big, install complexity, be inconvenient for。
Utility model content
In order to solve above-mentioned technical problem, this utility model provides a kind of smokemeter heater。Smokemeter heater of the present utility model has automatic temp controller, it is not necessary to the devices such as external temperature controller, it is possible to the problem effectively solving smokemeter probe inner icing cold season, and volume is little, it is easy to install。
Concrete technical scheme of the present utility model is: a kind of smokemeter heater, including heating box shell, blowback heating chamber, blowback heating chamber end cap, heater, temperature switch and insulation filling materials。Described blowback heating chamber is provided with an opening, described blowback heating chamber end cap is covered on the opening part of described blowback heating chamber, the outside of described blowback heating chamber is all located at by described heater and temperature switch, described blowback heating chamber and blowback heating chamber end cap are all located in described heating box shell, and described insulation filling materials is located between heating box shell and blowback heating chamber, blowback heating chamber end cap。
Preferred as the technical program, described blowback heating chamber end cap is fixed on the opening part of blowback heating chamber end cap by screw。
Preferred as the technical program, described heating box shell includes housing and casing cover, and the opening of described blowback heating chamber is towards described casing cover；Described blowback heating chamber is provided with air inlet tube, and described air inlet tube communicates with the external world through housing, and described blowback heating chamber end cap is provided with terminal fitting of giving vent to anger, and described in terminal fitting of giving vent to anger run through described casing cover。
Preferred as the technical program, described air inlet tube is connected with blowback heating chamber by the air inlet terminal fitting being located on blowback heating chamber。
Preferred as the technical program, described housing is provided with locknut joint, and power line is connected with heater by described locknut joint。
Preferred as the technical program, described insulation filling materials is insulation asbestos。
The operation principles of technical solutions of the utility model is: be connected with terminal fitting of giving vent to anger one end of outgoing gas connection tube, and the other end of outgoing gas connection tube is installed on the probe of smokemeter。After being powered up, extraneous air accesses blowback heating chamber by air inlet tube, and after being heated by heater, air blows on probe again through outgoing gas connection tube, makes probe heat up。When temperature is lower than design temperature, temperature switch is in the conduction state；After reaching design temperature, temperature switch can disconnect automatically, and heater stops heating。
It is compared with the prior art, the beneficial effects of the utility model are: smokemeter heater of the present utility model has automatic temp controller, it is not necessary to the devices such as external temperature controller, it is possible to the problem effectively solving smokemeter probe inner icing cold season, and volume is little, it is easy to install。
