[0002] The toxic gas alarm consists of a detector and an alarm control host. It is widely used in petroleum, gas, chemicals, oil depots and other petrochemical industries where toxic gases exist. It is used to detect leaks in indoor and outdoor dangerous places. It is an important instrument to ensure production and personal safety.

[0003] In order to ensure the normal use of toxic and hazardous gas alarms, they need to be calibrated regularly according to the calibration procedures. In the existing technology, the calibration device is difficult to move; there is a risk of leakage of gas standard substances during the calibration process, and toxic gases will be directly discharged after the test, thereby polluting the environment.

[0038] It should be noted that the equipment to be inspected mentioned in the present utility model has the function of detecting toxic and harmful gases, mainly detecting the concentration of toxic gases through a probe, such as a toxic and harmful gas alarm;

[0039] Furthermore, the isolation box 1 is respectively provided with a zero-point gas cylinder inlet connected to the zero-point gas cylinder, a gas standard material inlet connected to the gas cylinder, a detection device connection port 3 connected to the probe of the device under test, and a gas outlet connected to the forced discharge device; the filter tank 7 is provided with an inlet and an outlet 9 connected to the forced discharge device;

[0040] When calibrating the equipment to be tested, first connect the gas cylinder gas inlet storing the gas standard substance to the isolation box 1; connect the equipment to be tested to the test equipment connection port 3, and connect the zero-point gas cylinder to the zero-point gas cylinder gas inlet;

[0041] During the calibration, the gas standard substance in the gas cylinder enters the isolation box 1 through the gas cylinder gas inlet, and the probe of the device under test detects the gas standard substance in the isolation box 1 to obtain its concentration information; at this time, the zero-point gas in the zero-point gas cylinder does not enter the isolation box 1;

[0042] If the indication error of the concentration point is within the allowable error of the device under test, it means that the device under test meets the requirements; close the gas cylinder, open the zero-point gas cylinder connected to the gas inlet of the zero-point gas cylinder, so that the zero-point gas enters the isolation box 1 and mixes with the gas standard substance in the isolation box 1 to form a mixed gas, and the mixed gas in the isolation box 1 is sucked into the filter tank 7 through the forced discharge device for filtration and discharge, until the concentration in the isolation box 1 measured by the device under test is the zero-point gas concentration;

[0043] If during the calibration process, the indication error of the device under test exceeds the allowable error of the device under test; after the calibration is completed, close the gas cylinder and open the zero-point gas cylinder to allow the zero-point gas to enter the isolation box 1 and mix with the gas standard substance in the isolation box 1 to form a mixed gas, and the mixed gas in the isolation box 1 is sucked into the filter tank 7 through the forced discharge device for filtration and discharge until the concentration in the isolation box 1 measured by the device under test is the zero-point gas concentration.

[0044] In some possible implementations, in order to effectively achieve the suction of the mixed gas in the isolation box 1 so that the toxic and harmful substances in the mixed gas can be filtered;

[0046] Preferably, the exhaust fan 4 is a forced exhaust fan, which is powered by a mobile power supply of 36V or less; a power interface 13 is provided in the housing 12;

[0047] A zero-point gas check valve 6 is provided on the gas inlet of the zero-point gas cylinder;

[0048] The exhaust fan 4 is installed on the gas outlet. When the exhaust fan 4 is turned on, the mixed gas in the isolation box 1 will enter the filter tank 7 under the action of the exhaust fan 4.

[0049] The detection device connection port 3 is mainly used to connect with the device under test;

[0050] The zero point gas check valve 6 is connected to the zero point gas cylinder to control the gas in the zero point gas cylinder to enter the isolation box 1. After the calibration is completed, the zero point gas check valve 6 is opened and the gas cylinder is closed. The zero point gas in the zero point gas cylinder enters the isolation box 1 and mixes with the gas standard substance to form a mixed gas. Under the action of the exhaust fan 4, the zero point gas enters the filter tank 7 for filtration treatment to empty the gas standard substance in the isolation box 1.

[0052] The detection device connection port 3 is provided with a thread; the detection device connection port 3 is connected to the detected device through a pipeline.

[0053] By setting the thread, the connection port 3 of the detection equipment is sealed and connected with the pipeline to avoid leakage of unfiltered gas standard substances.

[0054] In some possible implementations,

[0055] The air inlet is provided with a reverse tooth nozzle 2, and the reverse tooth nozzle 2 is connected to the gas cylinder through a pipeline.

[0056] A second inverted tooth nozzle 8 is arranged on the outside of the filter tank 7 and is arranged corresponding to the air inlet, and the second inverted tooth nozzle 8 is connected to the air pipeline; a third inverted tooth nozzle 5 connected to the air pipeline is arranged at the outlet of the exhaust fan 4;

[0057] The arrangement of the inverted tooth nozzle 1 2 , the inverted tooth nozzle 2 8 , and the inverted tooth nozzle 3 5 in the utility model is mainly to avoid gas leakage.

[0058] In some possible implementations, in order to effectively implement the installation and regeneration of the filter layer;

[0062] In the closed state, the pressing plate 10 is sealed and connected to the tank body, the pressing plate 10 and the tank body are connected by a hinge, and the pressing plate 10 and the tank body are fixed by a latch 11;

[0063] During the inspection, the pressure plate 10 closes the replacement port and is sealed with the tank body to prevent the untreated mixed gas from leaking out; when the discharged gas after being treated by the filter layer does not meet the standard, the filter layer is regenerated.

[0064] In some possible implementations,

[0065] The filter layer is a desulfurization filter layer, which is made of a desulfurizer and is used to adsorb toxic and harmful substances in the mixed gas. The desulfurizer can be regenerated and reused, reducing the cost of use and the cost of pollutant treatment. During regeneration, the zero-point gas cylinder contains air. When the desulfurizer needs to be regenerated, the forced exhaust fan is started, and the desulfurizer is fully contacted with the air entering the filter tank 7 from the zero-point gas check valve 6 for oxidation regeneration.

[0066] Furthermore, the outer shell 12, the tank body and the isolation box 1 are integrally formed, and a handle 14 is provided on the top of the isolation box 1, which is light in weight and easy to carry.

[0067] Furthermore, the outer shell 12 is a hollow structure, which can effectively reduce weight; the outer shell 12 includes a fixed shell respectively connected to the top of the tank body and the bottom of the isolation box 1 and provided with an opening, and a shell body used to close the opening and hinged to the fixed shell; the setting of the opening makes it easy to inspect and replace the exhaust fan 4, and the fixed shell and the shell body are locked with a lock 15.
