Embodiment Construction
[0028] Now in conjunction with accompanying drawing, the present invention is described in further detail.
[0029] Such as figure 1 and figure 2 The shown ammonia refrigeration intercooler includes an intercooler tank body, and a coil 15 for high-pressure ammonia heat exchange is arranged in the intercooler tank body, and a tubular convection tube 17 is welded in the center of the coil tube; the superheated ammonia from the first-stage compression The steam pipe 1 passes through the gas-liquid separator tank 12 through the air guide pipe 7 and then penetrates into the tank of the intercooler, and the outlet of the air guide pipe is provided with an air outlet screen cage 8, and the upper wall of the air guide pipe 7 is welded with blades 5 with an angle. There is a gap between the blades, and a tubular outer cylinder 6 is welded on the outside of the blade 5 with an inclination; an isolation plate 9 and a baffle plate 10 are arranged in the tank of the intercooler; the isol...

The invention discloses an ammonia refrigeration intercooler. A high-pressure ammonia liquid heat exchange coil is arranged in the tank, and a tubular convection cylinder is welded in the center of the coil; the air guide pipe goes deep into the convection cylinder and the nozzle is provided with an air outlet screen cage. Angled vanes are welded on the outer wall of the air duct, and there are gaps between the inclined vanes, and a tubular outer cylinder is welded on the inclined vanes; the gas-liquid separator tank is equipped with a separation plate and a baffle; the separation plate will The tank body is separated, so that the ammonia vapor can only rise along the gap between the blades with angles; the baffle blocks the ammonia vapor, so that the ammonia vapor can only deflect and rise; the separation plate is equipped with a liquid flow pipe that opens downward; The upper part of the intercooler tank is provided with an exhaust pipe for secondary compression. The invention thoroughly removes the liquid ammonia carried in the ammonia vapor, improves the working efficiency and performance of the secondary compression, and improves the heat transfer coefficient of the coil by setting the convection cylinder, which is beneficial to the cooling of the high-pressure ammonia liquid in the coil.
Description
technical field [0001] The invention relates to an intercooler used in a double-stage compression ammonia refrigeration device, in which ammonia vapor is cooled after being compressed in the first stage before entering the second-stage compressor. Background technique [0002] Ammonia has excellent thermodynamic properties, and ammonia is generally used as a refrigerant in larger refrigeration systems. In practical application, when the required low temperature is lower than -20°C, two-stage compressors are generally used to complete the compression work. The first-stage compression sucks in the low-temperature steam from the evaporator, and discharges the medium-pressure superheated gas after compression. [0003] The medium-pressure superheated gas is generally cooled to about 0°C through the intercooler, and the ammonia vapor saturation treatment is completed at the same time, followed by ammonia gas-liquid separation and then sucked into the high-pressure stage for compr...
