Description

Ammonia content detection device Technical Field The utility model relates to the technical field of ammonia content detection, in particular to an ammonia content detection device. Background Ammonia belongs to poisonous and harmful gases, but ammonia is very soluble in water, the existing ammonia content detection device mostly needs to use proper absorption liquid to absorb NH3 in sample gas, then an ion chromatograph or a spectrophotometer and other instruments are used for measuring the concentration of the absorption liquid, the method has relatively high measurement accuracy on low-concentration ammonia, but the operation process is relatively complicated, and proper dilution multiple can be determined only by judging according to experience or repeatedly testing for many times, so that the ammonia detection process is time-consuming and laborious, the requirement on hardware is high, and the gas chromatographic column cannot accept extremely alkaline gas due to uncontrollable pressure of the gas, and the ammonia belongs to poisonous and harmful explosive gas, so that the detection risk of the ammonia is high. Disclosure of utility model The utility model aims to overcome the defects, and provides the ammonia gas and ammonia content detection device which can enable the detection process of ammonia gas to be time-saving and labor-saving, has lower requirements on hardware, can control the gas pressure, and reduces the risk of ammonia gas detection. In order to achieve the above purpose, the present utility model adopts the following technical scheme: The utility model provides an ammonia content detection device, includes gas collection bottle, UNICOM ware and cross valve, be equipped with the purified water that drips methyl red in the gas collection bottle, be equipped with the purified water in the gas collection bottle, be equipped with the scale outward of UNICOM ware, through handling the pipe intercommunication between the top of gas collection bottle and UNICOM ware, be provided with sealing valve on the processing pipe, the export of cross valve is connected through the connecting pipe to the bottom of UNICOM ware, three import of cross valve are connected with water pipe, ammonia pipe and nitrogen pipe respectively, be provided with ball valve, stop valve and manometer one on the connecting pipe, be provided with the pressure differential valve on the ammonia pipe. Further, one end of the treatment pipe extending into the gas collection bottle extends to the position below the liquid level of the purified water. Further, an exhaust pipe is arranged on the gas collection bottle, and the bottom end of the exhaust pipe is arranged above the liquid level of the purified water. Further, a second pressure gauge is arranged on the ammonia pipe. Further, a water inlet valve is arranged on the water pipe. Further, a nitrogen valve and a pressure gauge III are arranged on the nitrogen pipe. The beneficial effects of the utility model are as follows: 1. The sealing valve is opened, nitrogen is fed into the communicating device through the nitrogen pipe, the four-way valve and the connecting pipe, the inside of the communicating device is purged, and the purged nitrogen is discharged from the gas collecting bottle through the treatment pipe; 3. After the ammonia gas enters, water is fed into the communicating device through the water pipe, the four-way valve and the connecting pipe, and after the water feeding is finished, the concentration of the ammonia gas is obtained by reading the scale outside the communicating device; 4.
