Description

Volatile organic compound monitoring devices

Technical Field

The utility model relates to a monitoring devices, concretely relates to volatile organic compounds monitoring devices.

Background

Organic matters such as methane have volatility, need monitor volatile organic matters in industrial production, but current monitoring devices mostly need be provided with the drier case and carry out the dewatering, so both increased the cost, volatile organic matters have after the drier case to remain moreover, can influence the accuracy of data like this when the monitoring.

SUMMERY OF THE UTILITY MODEL

In order to solve the above problem, the utility model adopts the following technical scheme: the utility model provides a volatile organic compounds monitoring devices, includes the casing, be provided with liquid crystal display on the casing, be provided with the monitoring case in the casing, the monitoring incasement is provided with the light ion monitor, the monitoring case is connected with the check valve through spiral heating pipe, the check valve is connected with the sampling pipe, be provided with the draught fan on the sampling pipe, the sampling pipe outside is provided with electric tracing band one, heat preservation one, the outside cover of spiral heating pipe is equipped with fixed pipe, fixed outside of tubes is provided with electric tracing band two, heat preservation two, the monitoring case is connected with the blast pipe, be provided with the solenoid valve on the blast pipe.

Be provided with the controller in the casing, liquid crystal display, light ion monitor, draught fan, solenoid valve, electric tracing area one, electric tracing area two and controller electric connection are favorable to each electric work of better control, and the result of use is better.

STC89C52RC singlechip controller is selected for the controller, is favorable to the work of each electric component of better control, and the result of use is better.

The first heat-insulating layer and the second heat-insulating layer are high-temperature-resistant heat-insulating cotton layers, so that better heat insulation is facilitated, and the heat insulation effect is good.

Compared with the prior art, the utility model, have following advantage: the utility model discloses simple structure adopts spiral heating pipe structure to and the outside electric heating band setting of sampling pipe, can heat volatile organic compounds fast, whole high temperature can effectively avoid the production of comdenstion water, need not use the drier case, has improved detection effect greatly.
