Abstract
The utility model discloses a kind of condenser system for hydrogen fluoride production, including the primary cooler, thick cool condenser and one-level secondary condenser being sequentially connected, the cooling medium of thick cool condenser uses circulating water, and the cooling medium of one-level secondary condenser uses hypothermic saline.The utility model provides a kind of condenser system for hydrogen fluoride production for the corrosion to condenser that can reduce hydrogen fluoride.
Description
Technical field
It the utility model is related to hydrogen fluoride production field, more particularly to a kind of condenser system for hydrogen fluoride production.
Background technology
Hydrogen fluoride has extremely wide purposes at industry, national defence and civilian aspect, is the basic material of Organic fluoride industry.
Mainly for the production of fluorinated refrigerant, fluoroplastics, villiaumite etc..Now mainly it is made both at home and abroad using fluorite and sulfuric acid reaction.
The production procedure of hydrogen fluoride is：Fluorspar powder is delivered into rotary reaction furnace reaction, by oleum and by sulfuric acid absorption
The sulfuric acid that tower absorbs hydrogen fluoride in tail gas delivers to nitration mixture groove, is mixed herein with the diluted acid from scrubbing tower, and nitration mixture enters revolution
Reacting furnace, the product gas of reaction initially enters deduster, scrubbing tower dedusting, cooling, then into primary cooler and one-level two level
Condenser, scrubbing tower is returned in the condensate liquid that primary cooler obtains, passes through reboiler in the condensate liquid that one-level secondary condenser obtains
The heavy constituents such as sulfuric acid, water are removed with rectifying column, rectifying column kettle liquid returns to scrubbing tower, and overhead distillate enters degassing tower removing dioxy
Change the light components such as sulphur, ocratation.
The material of condenser is mostly carbon steel, and hydrogen fluoride can produce to condenser to be corroded, and the cooling medium one of condenser
As be hypothermic saline, corrosion of the hydrogen fluoride to condenser can be aggravated.
Utility model content
The utility model is in order to overcome deficiency of the prior art, there is provided a kind of condensed system for hydrogen fluoride production
System, can reduce corrosion of the hydrogen fluoride to condenser.
To achieve these goals, the utility model uses following technical scheme：
A kind of condenser system for hydrogen fluoride production, including primary cooler, thick cool condenser and the one-level two being sequentially connected
Level condenser, the cooling medium of thick cool condenser use circulating water, and the cooling medium of one-level secondary condenser uses low temperature
Salt solution.The cooling water first passed through in condensation process in thick cool condenser cools down hydrogen fluoride gas, makes partially fluorinated hydrogen
Body fluid, then cooled down by the hypothermic saline depth in cold two cool condenser, make not liquefied hydrogen fluoride gas liquefaction.So
Good effect of heat exchange, and most of gas first uses cooling water cooling liquid, it is not liquefied to be cooled down again with hypothermic saline, so reduce
The hypothermic saline amount used, the energy consumption of cold two cool condenser can be reduced, reduce the size of cold two cool condenser, and dropped
The low corrosiveness of hypothermic saline two cool condenser cold to one.
Preferably, thick cool condenser cooling water is cooled down by a cool tower.
Preferably, thick cool condenser and one-level secondary condenser are vertical (type) condenser.The condenser pipe of horizontal condenser
It is horizontal, because condenser pipe is longer, always some, in this position accumulating liquid hydrogen fluoride, extends fluorination less than level
The time of contact of hydrogen and condenser pipe, thus corrode aggravation；On the other hand, due to the horizontal installation of condenser, hydrogen fluoride gas is cold
Skewness in condenser, the probability of every condenser pipe of condenser contact hydrogen fluoride are also different, extent of corrosion also not phase
Together.Condenser is arranged to vertical, can overcome the shortcomings of horizontal condenser, reaches the purpose for reducing corrosion.
Preferably, it is provided with crude product groove on thick cool condenser and one-level secondary condenser.
Therefore, the utility model has the advantages that：Can reduce the hypothermic saline amount used, reduce it is one cold two cold
The energy consumption of condenser, the size for reducing cold two cool condenser, and reduce the corrosion of condenser.

Embodiment
Below by specific embodiment, and with reference to accompanying drawing, the technical solution of the utility model is made more specifically
It is bright.
As shown in figure 1, a kind of condenser system for hydrogen fluoride production, including the primary cooler 1, thick cold solidifying being sequentially connected
Device 2 and one-level secondary condenser 3, the cooling medium of thick cool condenser 1 use circulating water, and the thick cooling water of cool condenser 1 leads to
Cross a cool tower 4 to be cooled down, the cooling medium of one-level secondary condenser 3 uses hypothermic saline.Thick cool condenser 2 and one
Crude product groove 5 is provided with level secondary condenser 3.Primary cooler 1 is provided with primary cooler hydrogen fluoride import 6, primary cooler hydrogen fluoride goes out
Mouth 7, primary cooler cooling water inlet 8, primary cooler coolant outlet 9 and residual acid outlet 10, thick cool condenser 2 are provided with slightly cold coagulate
Device hydrogen fluoride import 11, thick cool condenser hydrogen fluoride outlet 12, thick cool condenser cooling water inlet 13, thick cool condenser cooling water
Outlet 14 and thick cool condenser crude product outlet 15, one-level secondary condenser 3 be provided with one-level secondary condenser hydrogen fluoride import 16,
Hypothermic saline import 17, hypothermic saline outlet 18, one-level secondary condenser crude product outlet 19 and offgas outlet 20.
Thick cool condenser 2 and one-level secondary condenser 3 are vertical (type) condenser.
It is not new to this practicality although above-mentioned specific embodiment of the present utility model is described with reference to accompanying drawing
The limitation of type protection domain, one of ordinary skill in the art should be understood that on the basis of the technical solution of the utility model, ability
Field technique personnel need not pay the various modifications that creative work can make or deformation still in protection model of the present utility model
Within enclosing.
