Description

(54) DEVICE FOR DIVIDING LIQUID AMMONIA TO PHASES WHEN TREATING AGRICULTURAL1X

one

The invention relates to agricultural machinery, in particular, to devices for the separation of liquid ammonia into phases when processing agricultural materials and when applied to the soil.

A device for separating 5 liquid ammonia into phases when processing agricultural materials is known, comprising a separation chamber with an inlet pipe located therein with choke holes, on which the upper and lower reflectors are fixed, and S also pipelines for removal of the liquid and gas phases of ammonia 1 .

A disadvantage of the known device is that after separation, the gas phase is removed from the separator either into the material being processed or into the fertilizer tank. This requires the availability of additional technological valves (hoses, valves, compressor, etc.). In addition, the design of the known device does not allow optimal separation of ammonia into 20 liquid and gas phases, which leads to a decrease in the efficiency of the use of liquid ammonia.

MATERIALS

The purpose of the invention is to improve the use of liquid ammonia.

This goal is achieved by those. that a device for separating liquid ammonia into phases when processing agricultural materials, including a separation chamber with an inlet pipe located in it with choke holes, on which the upper and lower reflectors are fixed, as well as pipelines for removal of the liquid and gas phases of ammonia; pump and conical deflectors, the latter are mounted on the inlet pipe above the throttling openings between the upper and lower reflectors, and the pump is built into the pipework to drain base card phase, wherein the discharge portion is located last in the separation chamber and is formed with a horizontally disposed below the lower portion zagluschennym reflector having openings at the top.

The drawing shows schematically the proposed device for the separation of liquid ammonia into phases during the processing of agricultural materials.

The device consists of a separation chamber 1, in which an ammonia gas supply mixture of ammonia pipe 2 with choke holes 3 is located. On the pipe 2, the top 4 and bottom 5 reflectors are fixed, between which conical deflectors 6 are mounted above the choke holes 3. Discharge from the separation chamber 1, the ammonia gas phase is activated by a pump 7 integrated in a discharge pipe 8, the pressure section 9 of which is located in the separation chamber. The latter is made with a horizontal section 10, horizontally located under the lower reflector 5, having holes 11 in the upper part. The ammonia liquid phase is discharged from the separation chamber 1 via a branch pipe 12.

The device works as follows.

Ammonia from the tank (not shown) receives pressure by pressure through supply line 2 into separation chamber 1 and exits through throttle holes 3. Since the pressure in chamber 1 is atmospheric, then when ammonia leaves throttle holes 3, its adiabatic expansion occurs. Expanding, ammonia is transformed into a supercooled liquid phase of 85 ° / o and a gas phase constituting from the total volume of ammonia entering chamber 1. Since ammonia has high heat transfer, the supercooled liquid phase is a stable liquid having temperature from -33.4 ° C to -67 ° C. The supercooled liquid phase flows down the conical deflectors 6, which contribute to a more rapid cooling of ammonia. Next, the liquid phase enters the lower reflector 5 and is collected in the lower part of chamber 1. From chamber I), through conduit 12, the liquid phase is fed by gravity either to agricultural material or to working bodies of agricultural mash to introduce it into the soil. The gas phase is collected at the top of chamber 1, from where pump 7

It is supplied to the pipeline 8. The pump 7 capacity is chosen such that it ensures that in the steady-state process the pressure in the chamber is 1 of the order (13 ... 15) X.

Saturated ammonia vapors, supplied by pasas 7 to the openings 11 of the horizontal section 10 of the pipeline 8, pass through a layer of the previously separated supercooled liquid phase and condense.

The use of the proposed device will allow for the condensation of the gas phase to the liquid and exclude its supply to agricultural materials and soil, which will drastically reduce ammonia loss from evaporation.
