Radial phase guide jet tray 1200 mm diameter 316L tower plate
1. Hualai factory radial phase guide jet tray,
This is an efficient tray developed on the basis of new vertical
sieve tray. It has good adaptability to the conditions of large
diameter tower and high gas-liquid load. Radial phase guide jet
tray has the characteristics of high flux, high efficiency, low
pressure, high operation flexibility, anti blocking and long
operation cycle.
2. Various types of tower trays,
| Type | Advantage | Disadvantage | Scope |
| Bubble cap tray | Mature, wide operation range | Complex structure, high resistance and low production capacity | Some special towers requiring good flexibility of operation |
| Floating valve tray | High efficiency and wide operation range | Using stainless steel, the float valve is easy to fall off | The separation requirement is high and the load changes greatly;
Crude atmospheric fractionator |
| Sieve tray | High efficiency and low cost | The installation should be horizontal, easy to block and narrow
operation range | The separation requirement is high, and there are many trays;
Propylene tower in chemical industry |
| Jet tray | Simple structure and large production capacity | Narrow operation range and low efficiency | Flash tower with lower separation requirements |
| Slant-Hole Tray | Large production capacity and high efficiency | The operating range is narrower than that of valve tower and bubble
cap tower | High separation requirements and large production capacity |
3. Hualai factory of tower trays and tower packing,
Our main business runs around columns / towers, which are widely
used in oil refinery, petrol-chemical industry, chemical industry,
pharmacy, fertilizer industry, etc. With the customers’ requirement
for full series of tower internal products, we are working with
famous universities in related area, and developing our capacity in
tower internal designing, manufacturing and service. We can now
design, produce and supply liquid distributor, liquid collector and
re-distributor, structured packing support, random packing support,
bed limiter, chimney trays, etc.
With many advanced machines and skilled workers, we also provide
custom fabrication service. It can be wire mesh or steel plate
products, or something like that. Show us your drawings or tell us
your ideas, we will try to make the special products for you.
4. Where is radial phase guide jet tray from?
Vertical sieve plate
Several large holes (100 ~ 200 mm in diameter) are arranged on the
tray. On the holes, a bubble cap with many sieve holes on the side
wall is set. There is a gap at the bottom of the bubble cap for
liquid to enter into the cap.
The two-phase upward flow is formed by drawing the liquid into the
hood from the bottom gap of the hood into a liquid film, and the
two-phase separation occurs after the two-phase flow is ejected
through the sieve holes on the side wall of the hood, that is, the
gas rises and the liquid falls back to the tray. The liquid flow
from the tray inlet to the downcomer will experience the above
process many times.
Compared with the ordinary sieve plate, the vertical sieve plate
provides a large and constantly updated interphase contact surface
for gas-liquid two-phase, which strengthens the mass transfer
process; The initial velocity of droplets in the vertical direction
is zero, which reduces the entrainment of liquid foam. Therefore,
the vertical sieve plate can obtain higher tray efficiency and
larger production capacity.
