Description
Technical field
The utility model relates to a kind of water-bath type liquid nitrogen vaporizer.
Background technology
Nitrogen is widely used at chemical field as a kind of inert gas, liquid nitrogen being converted into nitrogen use adopts the method for heating water bath that low temperature liquid nitrogen is converted into gas often, this converting apparatus energy consumption is comparatively large, and in converting heat process, used heat is not fully utilized.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of water-bath type liquid nitrogen vaporizer, overcomes deficiency of the prior art.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: water-bath type liquid nitrogen vaporizer, comprise tank, have above described tank set gradually side by side vaporium, gas-liquid mixed room and cooling chamber, separated by the first dividing plate between described vaporium and described gas-liquid mixed room, described first dividing plate has the through steam hole of multiple and described vaporium and described gas-liquid mixed room;
Separated by second partition between described gas-liquid mixed room and described cooling chamber, described second partition bottom have multiple and described gas-liquid mixed room and described cooling chamber through mix pore;
The bottom of described vaporium and the bottom of described cooling chamber all through with described tank, in described tank, there is heating wire;
Described cooling chamber lateral wall bottom has liquid nitrogen import, and described second partition top has and exports with described gas-liquid mixed room and the through liquid nitrogen of described cooling chamber;
In described cooling chamber, there is cooling coil, the two ends of described cooling coil respectively with described liquid nitrogen import and described liquid nitrogen outlet, described cooling chamber top has nitrogen outlet.
Further, described vaporium lateral wall has retaining mouth.
Further, described tank sidewall has delivery port.
Further, in described nitrogen outlet, there is drying tube.
The advantage that the utility model has and good effect are: owing to adopting technique scheme, utilize steam to cryogenic nitrogen transferring energy, liquid nitrogen transforms faster, utilizes the liquid nitrogen of low temperature that waste steam condensation is separated, water vapour can recycle, and has saved the energy greatly.

Detailed description of the invention
As shown in Figure 1, a kind of water-bath type liquid nitrogen vaporizer, comprise tank 1, have above tank 1 set gradually side by side vaporium 2, gas-liquid mixed room 3 and cooling chamber 4, separated by the first dividing plate 5 between vaporium 2 and gas-liquid mixed room 3, the first dividing plate 5 has multiple with vaporium 2 with the through steam hole 7 of gas-liquid mixing chamber 3;
Separated by second partition 6 between gas-liquid mixed room 3 and cooling chamber 4, second partition 6 bottom have multiple with gas-liquid mixed room 3 and cooling chamber 4 through mix pore 8;
The bottom of vaporium 2 and the bottom of cooling chamber 4 all through with tank 1, there is in tank 1 heating wire 9;
Cooling chamber 4 lateral wall bottom has liquid nitrogen import 14, and second partition 6 top has and exports 12 with gas-liquid mixed room 3 and the through liquid nitrogen of cooling chamber 4;
Have cooling coil 10 in cooling chamber 4, the two ends of cooling coil 10 export 12 with liquid nitrogen import 14 and liquid nitrogen respectively and are communicated with, and cooling chamber 4 top has nitrogen outlet 13.
Vaporium 2 lateral wall has retaining mouth 11.
Tank 1 sidewall has delivery port 15.
There is in nitrogen outlet 13 drying tube 16.
The course of work of this example: retaining in tank 1, heating wire 9 feed trough adds thermogenetic steam and enters vaporium 2, and steam enters gas-liquid mixed room 3 by the steam hole 7 on the first dividing plate 5;
Liquid nitrogen enters gas-liquid mixed room 3 by liquid nitrogen import 14 by cooling coil 10, the heat gasification that liquid nitrogen absorbs steam in gas-liquid mixed room 3 is nitrogen, nitrogen enters cooling chamber 4 from the mixing pore 8 second partition 6 together with steam, cooling coil 10 pairs of gaseous mixtures carry out condensation, flow into after steam-condensation in tank 1 and recycle, nitrogen blows out from nitrogen outlet 13 drying pipe 16.
Above embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
