Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic front view of the present invention.
Detailed Description
Referring to fig. 1, a flue gas particulate matter sampling cabinet, including the cabinet body 1, install two vacuum pumps 2 in the cabinet body 1, two vacuum pumps 2 pass through the pipeline in proper order with install flowmeter 3, regulating switch 4, cartridge filter 5, filter cup 6 and be connected at cabinet body 1 internal, filter cup 6 again through the pipeline with install the external gas washing bottle 7 of cabinet and be connected, be provided with foaming pipe 8 in gas washing bottle 7, foaming pipe 8 is connected with sampling gun 9.
The free end of the foaming pipe 8 extends to the bottom of the cavity of the gas washing bottle 7, after the gas entering the gas washing bottle 7 from the sampling gun 9 is fully mixed and contacted with the absorption solvent in the gas washing bottle 7, impurities in the gas are primarily washed away, then the gas is subjected to secondary filtration through the filter cup 6 for filtering water and dust, and is subjected to tertiary filtration through the filter cartridge 5, and the filtered clean gas is discharged out of the cabinet body 1 through the regulating switch 4, the flowmeter 3 and the two vacuum pumps 2.
A temperature controller 10 connected with the sampling gun 9 through a lead, two first adjusting knobs 11 connected with the two vacuum pumps 2 through leads, and a second adjusting knob 12 connected with an auxiliary heating belt on the sampling gun 9 through a lead are arranged on the cabinet body 1. The clamping seat 13 is installed on the outer wall of one side of the cabinet body 1, the gas washing bottle 7 can be detachably installed on the clamping seat 13, and the clamping seat 13 is provided with a clamping groove matched with the shape and the specification of the gas washing bottle 7, so that the gas washing bottle 7 is convenient to replace and maintain. A lifting handle 14 is arranged at the top of the cabinet body 1, so that the cabinet body 1 can be lifted conveniently; the lower extreme is regular is provided with a plurality of truckles 15, is convenient for remove the cabinet body 1, saves strength.
The utility model discloses a conventional accessories of market purchase can accomplish the equipment of the sampling cabinet body 1, and structure safety is firm reliable, the stable performance, and it is convenient to maintain, and most accessories need not the customization, by a wide margin the reduction cost of manufacture, have reduced the use threshold of flue gas particulate matter sampling cabinet simultaneously, have fine promotion effect to trades such as especially smoke and dust concentration detection of environmental protection industry, laboratory research and development.
When the gas path system is used, the leakage protection switch is turned on, the sampling cabinet is powered on, the high-precision gas flowmeter switch is turned on, the flowmeter 3 starts to work, and real-time flow data of the gas path system is displayed and counted through the flowmeter display screen; a temperature controller switch is turned on, the temperature control system starts to work, and the controller controls the working temperature of the sampling head through the coordination of the thermal sensor and the DC24V auxiliary heat belt; turning on an adjusting switch 4 of the vacuum pump 2, electrifying the vacuum pump 2 to operate, forming negative pressure in a pipeline of the gas path system, starting the gas path system to work, and extracting a target flue gas sample by matching with a sampling gun 9; the vacuum pump 2 is controlled by a fine-tuning circuit module, the output power of the vacuum pump 2 is adjusted through an adjusting switch 4, and the flow values of the pipeline negative pressure and the gas fluid are accurately adjusted by matching with the adjusting switch 4; the method comprises the following steps that after particles of original smoke extracted by a sampling gun 9 are filtered by a sampling head, the original smoke enters a gas washing bottle 7 through a sampling gun body and a PU connecting pipeline for primary washing treatment, secondary treatment is carried out through a filter cup 6 for filtering water and dust, tertiary treatment is carried out through a filter cartridge 5, and finally clean gas flows through an adjusting switch 4, a flowmeter 3 and a vacuum pump 2 and is discharged; when the gas medium flow of the gas circuit system reaches the preset value of the high-precision gas flowmeter 3, the screen flickers for prompting, the circuit breaker of the vacuum pump 2 is closed, data is recorded, the temperature controller switch and the high-precision gas flowmeter switch are sequentially closed, the sampling head is picked off and stored, and the temperature controller finishes the task of sampling the flue gas.
