316l Plate 900mm Air Jet Distillation Tower Trays With Liquid Downcomer

316L plate 900mm air jet tower tray with liquid downcomer

1. Hualai factory air jet tower 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,

3. 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.

4. 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.

5. The main requirements of industrial production on tower trays are as follows:

1. The throughput should be large, that is, the gas-liquid flow rate per unit tower section should be large;
2. The tray efficiency should be high;
3. The pressure drop of tray should be low;
4. Flexible operation;

Among these requirements, the high efficiency should be considered for the separation operation requiring high purity of the product; For the general separation with large treatment capacity (such as crude oil distillation, etc.), the main consideration is large capacity of passing.
