It is easily liquefied into a colorless liquid and can be liquefied by pressurizing it at room temperature. Its boiling point is -33.5°C. It is also easily solidified into a snow-like solid. Its melting point is -77.75°C. It is soluble in water, ethanol and ether. It can be oxidized into nitric oxide in the presence of a catalyst. It can be directly synthesized from nitrogen and hydrogen. It can burn the skin, eyes and mucous membranes of the respiratory organs. Excessive inhalation can cause lung swelling and even death.

[0003] Ammonia purifiers are mostly connected by pipes, and leakage should be avoided during the use of the pipes.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Reference Figure 1-5The present invention provides a gas leakage detection device for an ammonia purifier, comprising a tank body 1, a gas delivery pipe 2 and a gas outlet pipe 3 fixedly mounted on the side wall of the tank body 1, a connecting pipe 4 fixedly mounted between each tank body 1, a detection mechanism 5 fixedly mounted on the connecting pipe 4, a warning mechanism 7 for reminding personnel is arranged inside the detection mechanism 5, and a driving mechanism 6 for driving the warning mechanism to alarm is arranged inside the detection mechanism 5; a lower chamber 501 and an upper chamber 502 are opened inside the detection mechanism 5; the warning mechanism 7 includes a A slider 701 is provided at the top of the slider 701, and two symmetrically arranged support rods 702 are fixedly installed at the upper end of the slider 701, and the top ends of the two support rods 702 penetrate the top wall of the upper chamber 502 and extend to the outside thereof, a second spring 703 is fixedly connected between the slider 701 and the top wall of the upper chamber 502, a conductor plate 704 is fixedly installed at the top end of the support rods 702, an alarm 705 is fixedly installed at the upper end of the detection mechanism 5, and a first conductive block 706 is fixedly installed at the bottom of the alarm 705, and the two first conductive blocks 706 are connected to power wires.

[0024] Compared with the prior art, the present invention sets a detection mechanism 5 on the connecting pipe to detect gas leakage at the weak point of the pipe. When ammonia leaks at the connecting pipe 4, the volume of ammonia in the lower chamber 501 gradually increases and enters the upper chamber 502 through the components in the driving mechanism 6. Driven by the driving mechanism 6, the second spring 703 contracts due to the thrust. Under the elastic force of the second spring 703, the slider moves upward, thereby driving the support rod 702 and the conductor plate 704 to move upward and gradually approach the alarm 705. When the conductor plate 704 and the first conductive block 706 are in contact, the circuit here is connected, and the alarm 705 sounds an alarm to remind the staff to perform maintenance.

[0025] Reference Figure 2-5 The driving mechanism 6 includes a slot 601 opened between the upper chamber 502 and the lower chamber 501, and two symmetrically arranged fixed tubes 603 are fixedly installed on the bottom wall of the slot 601, and the first piston 602 is slidably installed on the two fixed tubes 603. The fixed tubes 603 are sleeved with a first spring 604, and the two ends of the first spring 604 are respectively fixedly connected to the upper end of the first piston 602 and the bottom end of the slider 701, and the second spring 703 is sleeved on the fixed tube 603. The bottom ends of the two fixed tubes 603 are provided with a plurality of air inlets 605, and the upper ends of the fixed tubes 603 are provided with a plurality of air outlets 606.

[0026] In the embodiment of the present application, the present invention sets up a first piston 602, a fixed tube 603, a first spring 604 and other mechanisms. When ammonia leaks from the connecting tube, the ammonia in the lower chamber 50 gradually increases, the first piston 602 is lifted up by the gas, and the first piston 602 drives the first spring 604 to shrink the first spring 604, exposing multiple air inlets 605 at the lower end of the fixed tube 603, and the ammonia enters the fixed tube 603, and then enters the upper chamber 502 from the air outlet 606, thereby driving the warning mechanism 7 and separating the total volume of ammonia.

[0027] Reference Figure 2 A second conductive block 801 is slidably mounted on one of the fixed tubes 603, a third conductive block 802 is fixedly mounted on the top wall of the upper chamber 502, a third spring 803 is fixedly connected between the second conductive block 801 and the third conductive block 802, an exhaust pipe 804 is fixedly mounted in the middle of the detection mechanism 5, one end of the exhaust pipe 804 is fixedly connected to an existing air pump and a processing tank, and the second conductive block 801, the third conductive block 802 and the power supply wire are connected.

[0028] In the embodiment of the present application, the second conductive block 801 is lifted to the third conductive block 802 by the elastic force of the second spring 703. After the two are in contact, the circuit here is turned on, and the air pump is started to extract the ammonia out of the upper chamber 502, and discharge it into the treatment tank from the exhaust pipe 804 for treatment, thereby realizing the control of the air pump.

[0029] Reference Figure 2 , 6 A control mechanism 9 is provided inside the top wall of the detection mechanism 5, and the control mechanism 9 includes a groove 901 opened on the top wall of the upper chamber 502, a fixing plate 902 is fixedly installed on the inner wall of the groove 901, a telescopic rod 903 is fixedly installed on the upper end of the fixing plate 902, a second piston 904 is fixedly installed on the output end of the telescopic rod 903, a fourth spring 905 is sleeved on the telescopic rod 903, and both ends of the fourth spring 905 are fixedly connected to the side walls of the fixing plate 902 and the second piston 904.

[0030] In the embodiment of the present application, when ammonia is discharged from the exhaust pipe 804, the ammonia lifts the second piston 904, and the second piston 904 drives the telescopic rod 903 and the fourth spring 905 to extend, so that the second piston 904 is conductive, allowing the ammonia to smoothly enter the exhaust pipe 804. Since ammonia is easily soluble in water, back suction will be formed in the exhaust pipe 804, but the gravity of the water will suppress the second piston 904 so that the water cannot enter the upper chamber 502, thereby realizing the control of ammonia output and preventing ammonia back suction.

[0031] Reference Figure 2 , the volume of the upper chamber 502 is smaller than the volume of the lower chamber 501.

[0032] In the embodiment of the present application, the volume of the lower chamber 501 is designed to be larger to prevent the lower chamber 501 from being squeezed and ruptured due to excessive ammonia. The ammonia in the upper chamber 502 increases slowly, and the volume of the upper chamber 502 is designed to be smaller, which is beneficial to cost saving.

[0033] Reference Figure 6 The material of the second piston 904 is thermoplastic polyurethane.

[0034] In the embodiment of the present application, thermoplastic polyurethane has excellent wear resistance, excellent ozone resistance, high hardness, high strength, low temperature resistance, good oil resistance and chemical resistance, and the aqueous solution of ammonia is alkaline, which makes the second piston 904 last longer.

[0035] Working principle:

[0036] When ammonia leaks from the connecting pipe, the ammonia in the lower chamber 50 gradually increases, the first piston 602 is lifted up by the gas, the first piston 602 drives the first spring 604 to contract the first spring 604, and the multiple air inlets 605 at the lower end of the fixed tube 603 are exposed, the ammonia enters the fixed tube 603, and then enters the upper chamber 502 from the air outlet 606. When ammonia leaks from the connecting pipe 4, the volume of ammonia in the lower chamber 501 gradually increases, and enters the upper chamber 502 through the components in the driving mechanism 6. Driven by the driving mechanism 6, the second spring 703 is pushed and contracts. Under the elastic force of the second spring 703, the slider moves upward, thereby driving the support rod 702 and the conductor plate 704 to move upward and gradually approach the alarm 705. When the conductor plate 704 and the first conductor When the blocks 706 are in contact, the circuit here is connected, the alarm 705 sounds an alarm, and the second conductive block 801 is lifted to the third conductive block 802 under the elastic force of the second spring 703. After the two are in contact, the circuit here is turned on, and the air pump is started to extract the ammonia out of the upper chamber 502, and discharge it into the treatment tank from the exhaust pipe 804 for treatment. When the ammonia is discharged from the exhaust pipe 804, the ammonia lifts the second piston 904, and the second piston 904 drives the telescopic rod 903 and the fourth spring 905 to extend, so that the second piston 904 is turned on, so that the ammonia enters the exhaust pipe 804 smoothly. Since ammonia is easily soluble in water, it will form back suction in the exhaust pipe 804, but the gravity of the water will suppress the second piston 904 so that the water cannot enter the upper chamber 502.
