Description

in to f Device for the preparation of ammonia water The utility model relates to the processes of preparation of ammonia water for the production of liquid nitrogen fertilizers and can be used in the conditions of agricultural associations of teki private farm enterprises. various devices are known for producing a military solution of ammonia used for the preparation of nitrogen fertilizers (Wolfkovich et al. General chemical technology, ML, Pozharsky. et al machines and equipment for using liquid ammonia, m, Rosselkhozdat,) with the closest constructive solution As a useful model, we can consider the Installation for the production of an aqueous solution of ammonia (Certificate.) 5584 for the field I know the model registered on December 16 if97r, with priority of November 5 if96r application J: f6I2I632). This installation consists of a mixing tank with two inlet and tubing safety valves and a high pressure reduction unit: including shut-off valves and a pressure regulator. Direct disadvantages of the known devices are their large dimensions and the inability to transport , since the process of mixing with water is carried out with a liquid, anhydrous amshak, the purpose of the proposed utility model is to achieve mobility conditions by reducing the dimensions and increasing the arbitrariness of the path th simplification of the process of sueing | and ensuring high safety The indicated purpose of the utility model is achieved by the fact that the high-pressure cutting unit and the mixing tank are marked on a single movable frame and equipped with flexible hoses for connecting to the vehicle and the tank with ammonia liquid ZhL5 GOIC I / 00

 2 inlet, and nitrogen reduction cylinders, valves, valves, check valves, liquid ammonia measuring device (7M, A) were introduced into the reduction unit, and the direct-acting pressure regulator is made in the chamber diaphragm visa with a bypass, and a flexible hose connecting to the transport the means, sliding with the device for measuring liquid ammonia between them, the chamber diaphragm with bypass connected in series and through a check valve connected to the mixing tank; nitrogen gas cylinders are connected in series with each other and through purge valves and check valves are connected to the inlet of the valve connected to the liquid ammonia measuring device and a flexible hose with the gas space of the ammonia tank.

The analysis of patent, information and catalog materials on devices for the preparation of ammonia water by the fund of the Saratov Regional Universal Scientific and Technical Library, as well as by the official bulletin of utility models, industrial designs for 1994 July 1998, with respect to the set of essential features, allows us to conclude that the proposed useful lodel is not known from the prior art, it is new,

this device for the preparation of ammonia water is suggested by the practice of life, known similar devices have large dimensions due to the volume of mixing tanks. This is because the mixing is carried out with liquid, anhydrous ammonia, the present device for mixing with water uses gaseous ammonia. 3 gaseous state, liquid anhydrous ammonia, leaving, for example, from an ash-gas carrier, turns after a chamber diaphragm. As a result, a much smaller volume of water is required to obtain a certain concentration of ammonia water, and therefore, the dimensions are significantly reduced, which allows the proposed device to be made mobile and used in any private household, and the process is more secure,

A useful model of a device for preparing a shiak cart is illustrated in the drawing, on which a block diagram is presented.

The device consists of a high pressure reaution unit i and a mixing tank 2 with an absorber displaced on a rubber moving frame; THEY are equipped with flexible hoses for connecting 3 to a vehicle, for example, to an ammonia carrier (not shown) and an ammonia discharge tank (not shown). In addition, it includes nitrogen gas cylinders 4 for purging the system, purge valves, 7 Bj iIOiII zeirizhi 12DZL 15, liquid ammonia measuring device 16, chamber adaFragma 17 with bypass 18, non-return valves 19,20,21,22, safety valve 23 , water tank 24, valve 25 on the drain line,

A device for the preparation of ammonia wow works as follows,

the mobile unit of the device is connected to a vehicle, for example, an ammonia truck and communicates with it using flexible connection hoses 3. With the amshakoeoz tank drain valve (not shown) closed and the gate valve 15 of the mixing tank inlet 2 closed, the purge valves 5,6,7 closed , 8,9,11 opens the valves 12LZ, 14 on the piping of the liquid ammonia measuring device 16, opens the valve on the safety valve 23, and the discharge line of the safety valve 23 through valve C and the check valve 22 is connected to the receiving cartridge bkom mixing tank 2. In the closed valve 15 opens the receiving pipe used gearbox purge valve cylinder 4 with the nitrogen gas and valve 25 to line s.yaiva for 30 seconds. the piping of the device is purged with nitrogen at p 0.2 No, after purging the purge valve 5 and ventil 25 close the device; it is prepared for the discharge of ammonia; moreover, the valve 15 opens and the drain valve on the ammonia carrier is gradually opened (not according to | The amount of ammonia discharged into the mixing tank 2, is fixed by the liquid ammonia measuring device 16 (TSA) and is determined by the specified percentage of nitrogen content in the ash and water mixture; in the device, after the chamber adafrag 17 is formed

“4 gaseous ammonia and a pressure of the order of 0 | 05Sha is set. It enters the mixer. The mixing tank registers 2, which ensures quick, safe dissolution of gaseous amshak in water. If the pressure after the chamber diaphragm i becomes outside of 0.05 Sha, the safety valve 23 is activated, configured, for example, to Relieve from the safety valve 23 through valve C with a non-return valve 22 occurs in the adjacent pipe of the mixing tank 2. If the chamber diaphragm 17 fails to work , then the pressure is regulated by opening the valve 18 at the bypass; the excess pressure in the gas space of the ammonia carrier until the ammonia is completely drained is maintained by the ammonia compressor or through the purge valve 5 and the non-return valve 19 from the cylinders 4. When the pressure in the ammonia carrier and the device is set to 0 gC5SHA, the drain valve on the ash tanker (not shown) closes. After checking the oijTaTKa, the ammonia carrier drives off for a new portion of ammonia. The reappearing valve b opens and, when the valves 7j9 are closed, the open valve 15 takes 30 seconds, the device is nitrogen bound from the cylinders 1 to the tank 2. Then the valve 15 and valve C are closed after the valve is purged and closed, the device is transported to the next tank by an ammonia tanker,
