Abstract
The invention relates to a hydrogen peroxide concentration distillation tower which comprises a bottom cone shell, a tower body, a filler support, a filler, a filler press ring, a tank-type liquid distributor, a liquid collector and a top condenser. The hydrogen peroxide concentration distillation tower is characterized by further comprising a supporting frame, a liquid foam capturing filter net, a backflow connecting pipe and a backflow pipe, the liquid foam capturing filter net is arranged at a feeding hole in the tower body through the supporting frame, an impurity discharging hole is formed in the bottom cone shell below the feeding hole, the lower end of the supporting frame is connected on the bottom cone shell below the impurity discharging hole in a downward inclining manner, one end of the backflow pipe is positioned above the tank-type liquid distributor while the other end of the same extends out of the tower body, a backflow hole is formed in the top of the tower body, and one end of the backflow connecting pipe is connected with the backflow hole while the other end of the same is communicated with the backflow pipe. The hydrogen peroxide concentration distillation tower has the advantage of capability of prolonging recycling period of the filler.
Description
Technical field
The present invention relates to a kind of rectifying column, particularly relate to a kind of hydrogen peroxide and concentrate rectifying column.
Background technology
The rectifying column of hydrogen peroxide concentration at present includes for bottom conical shell, tower body, packing support, filler, filler pressing, tank type liquid distributor, liquid header and evaporator overhead condenser；Bottom conical shell is arranged on tower body lower end, is provided with charging hole bottom tower body, and packing support, filler, filler pressing and tank type liquid distributor, liquid header and evaporator overhead condenser are from bottom to top successively set in the tower body above charging hole；This hydrogen peroxide concentrates rectifying column and cannot be separated by impurity in gas-liquid in the course of the work, thus affect filler recycle the cycle.
Summary of the invention
For disadvantages mentioned above, the hydrogen peroxide that it is an object of the invention to provide a kind of cycle that recycles that can improve filler concentrates rectifying column.
The technology contents of the present invention is, a kind of hydrogen peroxide concentrates rectifying column, including for bottom conical shell, tower body, packing support, filler, filler pressing, tank type liquid distributor, liquid header and evaporator overhead condenser；Bottom conical shell is arranged on tower body lower end, is provided with charging hole in tower body lower end, and packing support, filler, filler pressing and tank type liquid distributor, liquid header and evaporator overhead condenser are from bottom to top successively set in the tower body above charging hole；It is characterized in that it also includes a bracing frame, liquid mist eliminating drainage screen, backflow connecting tube and return duct；At the charging hole that liquid mist eliminating drainage screen is mounted in tower body by bracing frame, the bottom conical shell below charging hole is provided with an impurity relief hole；On the downward-sloping bottom conical shell being connected to below impurity relief hole in bracing frame lower end；Return duct end is above tank type liquid distributor, and the return duct other end reaches outside tower body, is provided with a return port at tower body top, and backflow connecting tube one end is connected with return port, and the backflow connecting tube other end connects with return duct.
What the present invention was compared with prior art had is a little: the present invention passes through liquid mist eliminating drainage screen, and tentatively by magazins' layout in gas-liquid, after removing a part of impurity, that can effectively improve filler recycles the cycle；Increase return duct, the tank type liquid distributor that end, tower body top lime set is fed again in tower body is the most repeatedly purified utilization；Improve production efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Specific embodiment
As it is shown in figure 1, a kind of hydrogen peroxide concentrates rectifying column, including for bottom conical shell 1, tower body 2, packing support 3, filler 4, filler pressing 5, tank type liquid distributor 6, liquid header 7 and evaporator overhead condenser 8；Bottom conical shell 1 is arranged on tower body 2 lower end, be provided with charging hole 2.1 in tower body 2 lower end, packing support 3, filler 4, filler pressing 5 and tank type liquid distributor 6, liquid header 7 and evaporator overhead condenser 8 are from bottom to top successively set in the tower body 2 above charging hole 2.1；It is characterized in that it also includes a bracing frame 9, liquid mist eliminating drainage screen 10, backflow connecting tube 11 and return duct 12；Liquid mist eliminating drainage screen 10 passes through, at the charging hole 2.1 that bracing frame 9 is mounted in tower body 1, the bottom conical shell 1 below charging hole 2.1 to be provided with an impurity relief hole 1.1；On the downward-sloping bottom conical shell 1 being connected to below impurity relief hole 1.1 in bracing frame 9 lower end；Return duct 12 end is above tank type liquid distributor 6, and return duct 12 other end reaches outside tower body 2, is provided with a return port 2.1 at tower body 2 top, and backflow connecting tube 11 one end is connected with return port 2.1, and backflow connecting tube 11 other end connects with return duct 12.
