Description
Technical field
This utility model relates to a kind of recycling can, and a kind of novel fluohydric acid gas being applied in fluorination reaction reclaims
The fluohydric acid gas that tank, the mainly picoline quasi-aromatic compound fluorination reaction under the pressure of more than 3.0Mpa uses reclaims
Tank.
Background technology
Currently used fluohydric acid gas recycling can is upper feeding, bottom discharge formula, and is not provided with bottom insert canal, gets the raw materials ready the most every time
Time, the fluohydric acid gas temperature pressed through due to steel cylinder is of a relatively high, when entering fluohydric acid gas and receiving in tank, has part vaporization and enters
Absorption system；And when often secondary response terminates to reclaim fluohydric acid gas, there is also uncooled hydrogen fluoride gas and be received on tank adjacent two
The situation that mouth cannot effectively trap quickly through receiving tank.
Summary of the invention
The purpose of this utility model has been stopped the volatilization of fluohydric acid gas, has been improved and reclaim when being to provide a kind of simple in construction, operation
Rate, the novel fluohydric acid gas recycling can being applied in fluorination reaction of reduction fluohydric acid gas consumption, overcome the deficiencies in the prior art.
The novel fluohydric acid gas recycling can being applied in fluorination reaction of the present utility model, including the standoff tank of lower bands
Body, there is tank mouth the upper end of tank body, is furnished with upper cover at tank mouth, and the middle part of upper cover is provided with charging aperture；It is provided with out in tank body upper end
Material mouth, the inner chamber at tank body is provided with discharge nozzle, and one end of discharge nozzle is connected with discharging opening, and the other end of discharge nozzle is positioned at tank body
The bottom in chamber；Being provided with feed pipe in tank body, one end of feed pipe connects with described charging aperture, and the length of feed pipe is at least
800 millimeters；It is provided with outer layer in the outside of tank body, forms the chuck layer of Cooling Water flowing between outer layer and tank body, at outer layer
Bottom is provided with cooling water inlet, is provided with coolant outlet on the top of outer layer, passes through between cooling water inlet and coolant outlet
Chuck layer connects.
Homonymy at tank body is positioned at upper and lower parts and is provided with interface and liquid level face lower interface on liquid level face；Lower end at tank body
It is provided with standby discharging opening；Drain and standby charging aperture it is provided with at the top of tank body；It is provided with thermometer boss, temperature at tank body top
Degree meter interface connects the pillar being positioned at tank body.
The novel fluohydric acid gas recycling can being applied in fluorination reaction of the present utility model, compared with prior art, useful effect
Fruit is to be prevented effectively from volatilization loss when fluohydric acid gas is got the raw materials ready, and can be by fluohydric acid gas organic efficiency from 65% raising before
To more than 72%, reduce fluohydric acid gas consumption.It addition, when leakage maintenance occurs in top discharge mouth, it is not necessary to material in blow-down tank, non-
The most convenient.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model detailed description of the invention；
