Abstract
The utility model provides a spray-absorption device. By arranging the spray-absorption device between a gas-guide tube and a hydration tower of a combustion tower, arranging a cooling water jacket on the device, arranging a plurality of spraying nozzles in the device, and connecting the spraying nozzles with a purified water supply pipe, when purified water at normal temperature is sprayed into a cylinder body through the spraying nozzles to conduct spray absorption on phosphorus pentoxide gas guided by the gas-guide tube of the combustion tower, the high temperature of the high-temperature phosphorus pentoxide gas is greatly reduced after spray absorption of a large quantity of normal temperature purified water is conducted on the high-temperature phosphorus pentoxide gas, phosphoric acid is generated, and the phosphoric acid and unabsorbed phosphorus pentoxide gas which is about 5 percent of the entire gas enter the hydration tower through the discharge opening of the cylinder body, so that the purpose of reducing the internal temperature of the hydration tower is achieved. By adopting the utility model, spray absorption can be conducted on the high-temperature phosphorus pentoxide gas before the high-temperature phosphorus pentoxide gas enters the hydration tower, the phosphoric acid of which the temperature is 80 to 90 DEG C is generated, the temperature of the hydration tower is reduced, corrosion to the equipment of the hydration tower is reduced, the equipment service life is prolonged, and the purity of the phosphoric acid is improved.
Description
Technical field
The utility model relates to a kind of phosphorous chemical industry device, particularly a kind of spray absorption plant.
Background technology
At present, the hot method phosphorus of known two-step method is that yellow phosphorus burning and phosphorus pentoxide absorption hydration are carried out step by step, temperature reaches phosphorus pentoxide gas more than 563 ℃ and directly enters by wireway from combustion tower and carry out hydration reaction in the hydration tower, heat that phosphorus pentoxide gas is brought into and hydration reaction liberated heat use hydration tower temperature higher, aggravated the corrosion of hydration tower under acid condition, the foreign ion that corrosion produces influences phosphoric acid purity.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of spray absorption plant, can reduce the temperature of phosphorus pentoxide gas, reduces material the hydration tower is corroded.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of spray absorption plant, and the cylindrical shell two ends are provided with charging aperture and discharging opening, and cylindrical shell is provided with chuck outward, is provided with a plurality of spray nozzles in the cylindrical shell.
Described spray nozzle has 3 row.
The every row of described spray nozzle has 4.
The chuck lower end is provided with cooling water inlet.
The chuck upper end is provided with coolant outlet.
The cylindrical shell material is a tantalum alloy.
A kind of spray absorption plant that the utility model provides, by between the wireway of combustion tower and hydration tower, the spray absorption plant being set, on device, cooling water jecket is set, and in device, a plurality of spray nozzles are set, and spray nozzle is connected with the pure water feed pipe, the normal temperature pure water is sprayed in the cylindrical shell from spray nozzle, the phosphorus pentoxide gas that wireway from combustion tower is come sprays absorption, temperature reduced greatly after the phosphorus pentoxide high-temperature gas was absorbed generation phosphoric acid by a large amount of normal temperature pure water sprays, phosphoric acid that generates and unabsorbed phosphorus pentoxide gas (about 5%) enter the hydration tower from the discharging opening of cylindrical shell, reach the purpose that reduces hydration tower internal temperature.Simultaneously, cooling water enters from the cooling water inlet of chuck bottom, carries out with cylindrical shell that the coolant outlet from top flows out after the heat exchange, reduces barrel temperature, shields.
The a plurality of spray nozzles that are provided with are evenly distributed on cylindrical shell, help the normal temperature pure water and fully contact with the phosphorus pentoxide gas of high temperature, except improving cooling-down effect, also help the abundant absorption of phosphoric acid.
Adopt the utility model, can before high temperature phosphorus pentoxide gas is entering the hydration tower, spray absorption, generate temperature at 80～90 degrees centigrade phosphoric acid, reduce the temperature of hydration tower, reduce the hydration tower is corroded, prolong service life of equipment, improve phosphoric acid purity.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the utility model overall structure schematic diagram;
The specific embodiment
As shown in Figure 1, a kind of spray absorption plant, cylindrical shell 1 two ends are provided with charging aperture 6 and discharging opening 7, and cylindrical shell 1 is outer to be provided with chuck 2, is provided with triplex row in the cylindrical shell 1, and four of every row are totally 12 spray nozzles 3, and spray nozzle 3 is evenly distributed on cylindrical shell 1.Chuck 2 lower ends are provided with cooling water inlet 4.Chuck 2 upper ends are provided with coolant outlet 5.Help the convection current of cooling water like this, avoiding occurring turbulent flow influences cooling-down effect.Cylindrical shell 1 material is a tantalum alloy, has increased the corrosion resistance of cylindrical shell 1.
The charging aperture 6 of cylindrical shell 1 is connected with the wireway of combustion tower, and the phosphorus pentoxide high-temperature gas enters cylindrical shell 1 thus, and discharging opening 7 is fixed on the hydration tower top cover and with the hydration tower and is communicated with, and the phosphoric acid that phosphorus pentoxide and water reaction generate enters the hydration tower through this; Cylindrical shell 1 is outer to be provided with chuck 2, coolant outlet 5 is arranged on it, it has cooling water inlet 4 down, is symmetrically distributed in the chuck both sides, the reduction straight barrel temperature that goes out to spring forth on advancing under the cooling water, and chuck 2 does not communicate with spray nozzle 3 or straight barrel 1.
The pure water feed pipe of normal temperature is connected with each spray nozzle 3, is used for the pure water spray, and water spray can be by caliber and the Flux Valve Control that is installed in supply channel, to adapt to the variation of process conditions and each tube side thermic load.
