Abstract
The utility model provides a device for detecting a gas exhaust pipeline of a burning tank of a laboratory. The device for detecting the gas exhaust pipeline of the burning tank of the laboratory comprises a gas concentration sensor, a control processor, a power supply, a gas exhaust device and an alarm module, wherein the gas concentration sensor is arranged in the gas exhaust pipeline, the gas concentration sensor and the alarm module are respectively connected with the control processor, when a collection value of the gas concentration sensor is higher than a gas concentration preset value of the control processor, the control processor starts the gas exhaust device, and the power supply supplies power for the control processor and the gas exhaust device. The device for detecting the gas exhaust pipeline of the burning tank of the laboratory has the advantages that due to the technical scheme, once compensation or air leakage of the gas exhaust pipeline is found, the alarm can alarm rapidly, and the device is convenient to use, simple in structure, convenient to maintain, low in processing cost, and the like.
Description
Technical field
The utility model relates to the pick-up unit of a kind of laboratory common equipment, especially relates to a kind of device that is used for test experience chamber combustion box gas exhaust piping.
Background technology
In existing technology, combustion box is the experimental facilities that arrives commonly used in the laboratory.The harmful exhaust that burning produces is the key factor of image experimenter health, so the poisonous fume needs in time be discharged to outdoor from combustion box.At this moment, gas exhaust piping has played vital role in the exhaust link.Gas exhaust piping is long to cause that the smooth or gas exhaust piping of exhaust is aging to cause technical matters appearance such as gas leakage and because the different environment in laboratory often causes, because some harmful gas is a colorless and odorless, so be difficult to be found, can have a strong impact on experimenter's health like this.
Summary of the invention
Problem to be solved in the utility model provide a kind of can be to the device of test experience chamber combustion box gas exhaust piping.
For solving the problems of the technologies described above, the technical solution adopted in the utility model comprises: gas concentration sensor, processor controls, power supply, exhaust apparatus, alarm module: gas concentration sensor is located in the gas exhaust piping, gas concentration sensor is connected with processor controls respectively with alarm module, when the collection value of gas concentration sensor was higher than the exhaust concentration set point of processor controls: processor controls started exhaust apparatus, and power supply is processor controls and exhaust apparatus power supply.
Further, described gas concentration sensor is not less than one.
Further, described gas concentration sensor comprises that first gas concentration sensor, second gas concentration sensor and alarm module are connected with processor controls respectively, the end of gas exhaust piping is provided with first gas concentration sensor, and the gas exhaust piping outlet is provided with second gas concentration sensor; When the collection value of first gas concentration sensor was higher than the exhaust concentration set point of processor controls: processor controls started exhaust apparatus, the explanation gas exhaust piping has the leak point when the collection value of second gas concentration sensor is lower than the collection value of the first gas concentration window device, then processor controls starts alarm module work.
Further, described alarm module is an alarm.
Advantage and the good effect that the utlity model has are: owing to adopting technique scheme, in case find gas outlet compensation or gas outlet gas leakage energy Rapid Alarm, use convenient; Have simple in structure, easy to maintenance, advantage such as processing cost is low.
