Description
Technical field
The utility model relates to a kind of sulfuric acid equipment for purifying, especially a kind of electro-medical sub level sulfuric acid equipment for purifying.
Background technology
Handled raw material, intermediate product, thick product etc. nearly all are mixtures in the Chemical Manufacture, and major part is the homogeneous phase system.Being further processing and using, often need be purer with these mixture separation or the material of pure state almost.Rectifying is to separate one of important method of homogeneous liquid mixture, belongs to the alternate interphase mass transfer process of gas-liquid.
Electro-medical sub level sulfuric acid equipment for purifying is transmission and the isolating theoretical basis of material balance of utilizing the alternate material of vapour-liquid, add generation second phase by means of the energy separation agent, through calculating meticulously and design, produce the different purification sulfuric acid of concentration, meet the different needs, thereby reach the purpose of energy-saving and environmental protection and comprehensive utilization of resources.
Electro-medical sub level sulfuric acid equipment for purifying adopts the coal heating technique at present, pollutes greatly, and adopts the single flash technology, and the quality of product can only reach analytically pure standard in the reagent of sulfuric acid; And raw material acid is without preheating, and the energy consumption height increases cost.
The utility model content
Technical problem to be solved in the utility model provides a kind of energy-conserving and environment-protective, electro-medical sub level sulfuric acid equipment for purifying that quality product is high.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of electro-medical sub level sulfuric acid equipment for purifying, comprise feed-pipe, interchanger, well heater, an evaporator room, concentrated acid pipe, its structural feature is: add two evaporator rooms, three evaporator rooms between an evaporator room and concentrated acid pipe, in two evaporator room exits one diluted acid pipe is set, three evaporator room exits are provided with two diluted acid pipes, between interchanger and well heater, add the spiral preheater, spiral preheater sealing is arranged in three evaporator rooms, communicates between spiral preheater and interchanger, the well heater.
Well heater changes the electric stove wire heating unit into by original coal heating unit.
Compared with prior art, the utility model technology has the following advantages:
1. owing to be provided with the spiral preheater, make the sulfuric acid of purifying when three evaporator rooms are effusive from the concentrated acid pipe,, utilize waste heat the raw material acid preheating in the spiral preheater through spiral preheater outside, enter heater heats after the raw material acid preheating again, the consumption of the energy has reduced 23%.
2. owing to increased by two evaporator rooms, three evaporator rooms, the sulfuric acid vapor of formation runs into tube wall and descends, and reaches condensation for the first time and condensation for the second time, produces two kinds of purification sulfuric acid that purity is different, and quality product is higher, satisfies different demands respectively and uses.
3. because well heater changes the electric stove wire heating unit into by original coal heating unit, reduce environmental pollution.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is the utility model electro-medical sub level sulfuric acid equipment for purifying structural representation.
Embodiment
As shown in Figure 1, the utility model comprises feed-pipe (1), interchanger (2), well heater (4), one evaporator room (5), concentrated acid pipe (8), between an evaporator room (5) and concentrated acid pipe (8), add two evaporator rooms (6), three evaporator rooms (7), in two evaporator rooms (6) exit one diluted acid pipe (9) is set, three evaporator rooms (7) exit is provided with two diluted acid pipes (10), between interchanger (2) and well heater (4), add spiral preheater (3), spiral preheater (3) sealing is arranged in three evaporator rooms (10), spiral preheater (3) and interchanger (2), well heater communicates between (4).Well heater (4) changes the electric stove wire heating unit into by original coal heating unit.
Raw material acid enters from feed-pipe (1), after interchanger (2) preheating for the first time, entering spiral preheater (3) secondary preheating, enter well heater (4) then and be heated to 280 ℃, the vapour-liquid two-phase system that forms in the back that is heated, reaching dregs because of each component volatilization in the mixture is different is separated by well heater (4) bottom, the sulfuric acid vapor of Xing Chenging flow into two evaporator rooms (6) from an evaporator room (5) then, sulfuric acid vapor runs into two evaporator rooms (6) locular wall, temperature drops to 220 ℃, reach condensation for the first time, produce a part of purity and be 95.5～97% purification sulfuric acid and flows out the cooling recovery from a diluted acid pipe (9); Another part sulfuric acid vapor arrives three evaporator rooms (7), meet once more with three evaporator rooms (7) locular wall, reach condensation for the second time, producing a part of purity and be 97～98% purification sulfuric acid flows out from concentrated acid pipe (8), cooling is reclaimed, another part sulfuric acid vapor flows out from two diluted acid pipes (10), and generation purity is 95.5～97% purification sulfuric acid, and cooling is reclaimed.Wherein, after three evaporator rooms (7) condensation, the purity that produces is that 97～98% purification sulfuric acid flows out from concentrated acid pipe (8), by way of spiral preheater (3) outside that sealing is provided with, this purification sulfuric acid runs into spiral preheater (3) pipe outer wall, its waste heat is absorbed by the raw material acid in the spiral preheater (3), thereby plays pre-heat effect.
The utility model, owing to be provided with spiral preheater (3), make the sulfuric acid of purifying when three evaporator rooms (7) are effusive from concentrated acid pipe (8), through spiral preheater (3) outside, utilize waste heat with the raw material acid preheating in the spiral preheater (3), enter well heater (4) heating after the raw material acid preheating again, the consumption of the energy has reduced 23%.Increased by two evaporator rooms (6), three evaporator rooms (7), the sulfuric acid vapor of formation runs into tube wall and descends, and reaches condensation for the first time and condensation for the second time, produces two kinds of purification sulfuric acid that purity is different, and quality product is higher, satisfies different user demands respectively.Well heater (4) changes the electric stove wire heating unit into by original coal heating unit, reduces environmental pollution.
