STT type Graphite packing tower
【Structure and characteristics】
Non-permeability graphite packed tower system used in hydrochloric acid, sulfuric acid and other corrosive media absorption, concentration, distillation, evaporation, filtration, washing and other chemical unit operation, it is a gas-liquid contact heat transfer, mass transfer process. In operation, gas and liquid flows for the current general direction. Liquid spray device from the top by sprinkling water and under the uniform, the gas rising from the bottom evenly, after gas-liquid two-phase contact between the surface of filler in order to carry out the delivery and quality of heat.
Graphite packing tower structure is simple, manufacturing convenience, the pressure drop in small, adaptable, they are advised to deal with viscous, easy blistering, heat-sensitive materials or corrosive small mass transfer rate from gas to control the materials, which are more widely applied, but the low efficiency, bulky equipment.
【Technical characteristics】
P: -0.1 ~ 0.5MPa
T: ~ 200 ℃
Specifications: DN200 ~ DN3600
Implementation of standards: HG/T2370-2005 "Graphite Chemical Equipment technology system"


SST type Graphite plate column
【Structure and characteristics】
Application of sieve-plate column is one of the first one of the towers. Chemical production in recent years has developed into a major one of mass transfer equipment. Sieve Tray Tower have intensive drilling small holes, so that gas through the sieve in the medium when the liquid drum tower on the board to carry out mass transfer into the process of the bubble.
Graphite plate column with simple structure, convenience, cost less than the bubble-cap tower and valve tower, and the handling capacity and efficiency were higher than the bubble plate towers, etc.. However, because of its flexible production of small, not suitable for low load conditions, as well as gas-liquid sieve blockage Xiao Yi shortcomings, with the result that the application of graphite plate column system rarely. Only in some high temperature and strong corrosion resistance is still useful occasions.
【Technical characteristics】
P: -0.1 ~ 0.5MPa
T: ~ 200 ℃
Specifications: DN200 ~ DN3600
Implementation of standards: HG/T2370-2005 "Graphite Chemical Equipment technology system"

SPT type Graphite bubble-cap tower
【Structure and characteristics】
Blister is a bubble column-type plate towers, gas (or steam) through the tower of the blister board, was dispersed phase with on-board liquid contact tower. It is a more complicated structure of the tower, and graphite materials, processing and installation of all becoming more and more trouble. At present, little used.
Blister tower by tower, blister, overflow weir and downcomer and vapor-liquid components, such as import and export, the Blister Trays are the main parts of the tower. Graphite has a circular blister blister blister and strip the two: the wider application of a circular blister, blister strip are generally used for large liquid-gas ratio of the occasion.
【Technical characteristics】
P: -0.1 ~ 0.5MPa
T: ~ 200 ℃
Specifications: DN200 ~ DN3600
Implementation of standards: HG/T2370-2005 "Graphite Chemical Equipment technology system"

STJ type Graphite quench tower
【Structure and characteristics】
Permeability graphite does not quench tower system used in high-temperature gas (corrosive flue gas, the burning of chlorine-containing waste gases) the rapid cooling.
But the principle of urgency: 1, liquid spray to remove the heat of vaporization; 2, graphite heat transfer away heat partitions; 3, spray liquid temperature below the gas temperature, heat transfer with each other. In operation. Gas and liquid flows for the current general direction. Liquid spray device from the top by sprinkling water and under the uniform, the gas rising from the bottom evenly, after gas-liquid two-phase contact between the surface of filler in order to carry out the delivery and quality of heat.
Graphite quench tower structure is simple, manufacturing convenience, the pressure drop, and adaptable to deal with the characteristics of large capacity.
【Technical characteristics】
P: -0.1 ~ 0.5MPa
T: ~ 1500 ℃
Specifications: DN200 ~ DN3600
Implementation of standards: HG/T2370-2005 "Graphite Chemical Equipment technology system"

SZG type Graphite Evaporator
【Structure and characteristics】
Non-permeability graphite system Evaporator corrosive materials used in evaporation! Such as: citric acid, lactic acid, phosphoric acid and so on.
The latest products of non-lined, all-graphite structure, this type of equipment, heat-resistant properties of radical quenching greatly mentioned pressure ability to achieve unprecedented 0.5MPa.
Graphite-lined steel can also brick (board) structure, but structure the existence of numerous factors such as glue joints, less performance for the general requirements of the occasion.
Generally with the use of graphite heater, graphite condenser, water jet pump sets, such as the use of forced circulation can be heated, the natural cycle of heating methods such as corrosion of materials used for evaporation.
【Technical characteristics】
P: negative ~ 0.5MPa
T: ~ 170 ℃
Specifications: DN200 ~ DN3600
Implementation of standards: HG/T2370-2005 "Graphite Chemical Equipment technology system"
