Abstract
The utility model provides a nitrogen blowing-drying system which is characterized by comprising an air compressor and a nitrogen making machine, wherein the air compressor is connected with an air storage tank A; the air storage tank A is sequentially connected with a C-stage filter, a refrigeration dryer, a T-stage filter, an A-stage filter and a water filtering device; the water filtering device is connected with the nitrogen making machine; the nitrogen making machine is connected with an air storage tank B; all the devices are connected with valves through pipelines. Nitrogen prepared by using the system has good effects on recycling and blowing-drying purified terephthalic acid.
Description
Technical field
The utility model relates to pure terephthalic acid to be recycled, and refers in particular to a kind of nitrogen blow-drying system.
background technology
In the process with alkali decrement waste water Slag recovering pure terephthalic acid, need to carry out processed to the crystal after filtering separation, in order to reduce the pollution to crystal, and consider the aspect factors such as cost, the inventor develops a kind of nitrogen blow-drying system, and this case produces thus.
Utility model content
The purpose of this utility model is to provide a kind of nitrogen blow-drying system, utilizes the nitrogen of inertia to dry up pure terephthalic acid's crystal, and not only efficiency is high, and pollution-free.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of nitrogen blow-drying system, comprise air compressor machine, Nitrogen plant, described air compressor machine is connected with gas-holder A, described gas-holder A and C level strainer, cooling driers, T level strainer, A level strainer is connected successively with water filtering device, and water filtering device is connected with Nitrogen plant, described Nitrogen plant is connected with gas-holder B, and above-mentioned each device is connected with valve with pipeline.
Adopt after such scheme, the utility model compared with prior art, has the following advantages:
Adopt after filtering layer by layer and can make pure nitrogen, pure terephthalic acid's crystal is polluted drying up Shi Buhui.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model;
Label declaration
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
As shown in the figure, a kind of nitrogen blow-drying system that the utility model discloses, comprise air compressor machine 1, Nitrogen plant 8, the air outlet valve of air compressor machine 1 is connected with the inlet mouth of gas-holder A2, the air outlet of gas-holder A2 is connected with C level strainer 3, after C level strainer 3, be connected with cooling driers 4, after cooling driers 4, be connected with T level strainer 5, A level strainer 6 and water filtering device 7, water device is connected with the inlet mouth of Nitrogen plant 8, the air outlet of Nitrogen plant 8 is connected with the inlet mouth of gas-holder B9, and the outlet pipe of gas-holder B9 is connected with the device of placing crystal.
After air compresses in air compressor machine 1, inject gas-holder A2, the effect that gas-holder A2 plays buffering and stores, then through C level strainer 3, carry out coarse filtration, by oil gas filterings a large amount of in pressurized air to 3PPM with the interior and particle 3um that filters out impurities, by cooling driers 4, lower the temperature again, condensation, remove the dust that water vapour and water of condensation are taken away, continue by T level strainer 5, by oil gas filterings a large amount of in pressurized air to 0.5PPM with the interior and particle 0.5um that filters out impurities, with A level strainer 6 by the accurate filtering of the micro-oil gas in pressurized air to 0.01PPM with impurity particle in interior while air to 0.01micron, reach the high goods pressurized air without oil standard.
Finally by water filtering device 7, enter into Nitrogen plant 8 and make nitrogen, by being stored in gas-holder B9, just can directly use.
Above are only specific embodiment of the utility model, but design concept of the present utility model is not limited to this, allly utilizes this design to carry out the change of unsubstantiality to the utility model, all should belong to the behavior of invading the utility model protection domain.
