Abstract
A kind of device for producing high pure oxygen and High Purity Nitrogen, including air compressor machine, chilldown system, prepurifier and ice chest；Main heat exchanger, expanding machine, subcooler, high-pressure tower, lower pressure column, domethanizing column and high-purity oxygen column are equipped with the ice chest；Prepurifier outlet divides two-way, is connected to main heat exchanger, high-pressure tower all the way；The expanded machine of another way is to main heat exchanger, then is connected to expander end, lower pressure column；High-pressure tower tower top outlet is connected to High Purity Nitrogen product supply pipeline；High-pressure tower oxygen-rich fluid outlet connection subcooler, divides two-way, is connected to lower pressure column all the way, another way is connected to domethanizing column；Lower pressure column purity nitrogen fluid outlet is connected to high-pressure tower；Demethanizer column overhead outlet connects high-purity oxygen column, and high-purity oxygen column tower reactor connects high-purity liquid oxygen product supply line.Single domethanizing column is provided with the utility model, the recovery rate of high pure oxygen, good economy performance can be improved on the basis of high-purity oxygen purity is ensured.
Description
Technical field
The utility model belongs to air purification technique field, and in particular to a kind of dress for producing high pure oxygen and High Purity Nitrogen
Put.
Background technology
Industrial gasses are called " blood " of industry.With the fast development of China's economic, industrial gasses are passed through as national
One of basic industries key element of helping, the critical role and effect in national economy are increasingly prominent.Especially with Internet era
Arrival, the industry such as electronics, polysilicon rises extensively, and the demand of the top student in industrial gasses --- high-purity gas is increasingly
It is more.
As the bulk gas in high-purity gas, high purity oxygen gas and high pure nitrogen answering in industries such as electronics, polysilicons
With more and more extensive, and current high pure oxygen is to be obtained from space division as byproduct production mostly, for production capacity relative requirements
Deficiency, High Purity Nitrogen are then to be obtained using the method for cryogenic rectification from nitrogen-making device.
High pure oxygen and High Purity Nitrogen can be prepared at the same time by only having minimal amount of device at present, still, in these devices, not had
The device of methane can be removed individually and thoroughly, during production, methane can be ignored by only extracting a few part at the middle part of rectifying column
The fluid of content causes the problem of recovery rate is low when producing high pure oxygen, also, oxygen is pure as the raw material for producing high pure oxygen
Degree is higher, and recovery rate is lower.
Therefore, it is not widely used.For needing the industry of the high pure oxygen of application and High Purity Nitrogen at the same time, still
It is difficult to meet the requirements.
Utility model content
The purpose of this utility model is to provide a kind of device for producing high pure oxygen and High Purity Nitrogen, high pure oxygen can be prepared at the same time
With two kinds of products of High Purity Nitrogen, the standard of high pure oxygen product oxygen content scope >=99.999% of acquisition, even up to ultrapure oxygen, oxygen
Content range >=99.9999%, High Purity Nitrogen product nitrogen content range >=99.999% of acquisition, respectively reaches national standard《GB/
T14599 pure oxygens, high pure oxygen and ultrapure oxygen》In high pure oxygen and《GB/T8979 purity nitrogens, High Purity Nitrogen and superpure nitrogen》In High Purity Nitrogen
Standard requirement.
In order to achieve the above object, the utility model provides following technical solution：
A kind of device for producing high pure oxygen and High Purity Nitrogen, including air compressor machine, chilldown system, prepurifier and ice chest；It is described
Main heat exchanger, expanding machine, subcooler, liquid nitrogen pump, high-pressure tower, lower pressure column, domethanizing column and high-purity oxygen column are equipped with ice chest；Its
In,
The main heat exchanger sets at least two cooling entrances and outlet, at least two re-heat entrances and outlet；The expanding machine by
Supercharging and expansion two parts composition；The subcooler sets cooling entrance and outlet, re-heat entrance and outlet；At the top of the high-pressure tower
Condenser is set, and tower body sets air intake and purity nitrogen fluid inlet, and tower top sets High Purity Nitrogen fluid outlet, and tower reactor sets oxygen-rich fluid and goes out
