Technical field

The utility model relates to a kind of pick-up unit, more particularly, relates to a kind of sense cigarette type fire-alarm detection system.

Background technology

Heritage cigarette type fire-alarm detection system is because its simple in structure, function singleness, and the flue dust particle diameter is uncontrollable, the temperature difference is big, accuracy of detection is low, when sense cigarette type fire-alarm is detected, require the flue dust particle diameter controlled, have a narrow range of temperature, the accuracy of detection height, and need carry out regulating and controlling to the fume amount that enters in the circulation air path, thus heritage cigarette type fire-alarm detection system can not meet the demands smokescope and particle diameter controlled, have a narrow range of temperature, needs that sense cigarette type alarm that accuracy of detection is high detects.

The utility model content

The purpose of this utility model is to overcome above-mentioned defective of the prior art, provide a kind of require the smog particle diameter controlled, have a narrow range of temperature, the accuracy of detection height, also can and enter the sense cigarette type fire-alarm detection system that the fume amount in the circulation air path is regulated to heating rate.

For achieving the above object, the technical scheme that the utility model provides is as follows: a kind of sense cigarette type fire-alarm detection system is provided, comprise a circulation air path, be installed in evaporator, well heater, circulating fan, orifice plate, filter screen, test platform in the circulation air path successively, offer a flue dust import on the described circulation air path, this flue dust import is connected with a flue dust generating means.

The beneficial effect of sense cigarette type fire-alarm detection system described in the utility model is: by adorn evaporator, well heater, circulating fan, orifice plate, test platform successively in circulation air path, offer a flue dust import on the described circulation air path, this flue dust import is connected with a flue dust generating means, when adopting this system to detect, also can be according to the needs control heating power of test, satisfy the needs that are rapidly heated, also can carry out precision control, and can regulate the fume amount that enters in the circulation air path to the temperature difference.Have smokescope and particle diameter controlled, have a narrow range of temperature, advantage that accuracy of detection is high.

Below in conjunction with drawings and Examples sense cigarette type fire-alarm detection system described in the utility model is described further.
