Pressure regulating valves are installed on outlet pipelines of the buffer tanks, pressure detectors are arranged on the nitrogen main pipes and connected with the pressure regulating valves, a communicating pipe is arranged between the outlet pipelines of the buffer tanks, and a valve is arranged on the communicating pipe. The supercharging system is connected onto two nitrogen main pipes, nitrogen in the nitrogen main pipes of a device for preparing methyl alcohol by using natural gas is pre-stored in two buffer tanks through the supercharger, and preset pressure intensity is reached. When supply failure of the nitrogen main pipes occurs or pressure of one nitrogen main pipe is reduced, the nitrogen in the corresponding buffer tank can be supplemented into the corresponding nitrogen main pipe, and enough time for safe device shutdown is ensured under the nitrogen interruption condition.
Description
Technical field
The utility model relates to the accessory system of using coke-stove gas and methanol from natural gas device, is specifically related to a kind of nitrogen gas supply system.
Background technology
Coke-stove gas, claims again oven gas, because combustible component is many, belongs to high heating value gas, raw gas or raw coke oven gas.Refer to several bituminous coal and be mixed with coal for coking, in coke oven, after high-temperature retorting, a kind of imflammable gas producing in output coke and tar product, is the byproduct of coking industry.Oven gas is mixture, its productive rate with form because of coal for coking quality to some extent difference different from coking condition.The device that uses coke-stove gas to prepare methyl alcohol needs to use nitrogen during the course, is equipped with corresponding coke-stove gas and prepares methanol device.At coke-stove gas, prepare in the device of methyl alcohol because nitrogen is many with point, by house steward, to each point, carry, but there is many defects in this mode, such as going wrong when nitrogen pipeline, interrupting appears in nitrogen supply (NS), prepares the compressor of methanol device and jumps car, and all control valves all cannot regulate in standard-sized sheet, complete shut-down state, will cause to produce and interrupt, total system stops production.When methanol, often use coke-stove gas methanol technics processed and methanol production process from natural gas, this two covers technique in use all needs to be equipped with nitrogen gas supply system.
In order to solve above-mentioned deficiency of the prior art, the utility model proposes a kind of new solution.
Utility model content
The purpose of this utility model is to provide a kind of nitrogen gas supply system.
For reaching above-mentioned purpose, the technical scheme that the utility model adopts is: a kind of nitrogen gas supply system, comprise methanol from natural gas device nitrogen header pipe and coke-stove gas methyl alcohol nitrogen header pipe processed, and in methanol from natural gas device nitrogen header pipe, be parallel with pressure charging system; Described pressure charging system comprises supercharger, two parallel connection buffer tanks that are connected with supercharger; On the outlet conduit of one of them surge tank, pressure-regulating valve is installed, and is connected with methanol from natural gas device nitrogen header pipe, in methanol from natural gas device nitrogen header pipe, be provided with pressure detector, this pressure detector is connected with this pressure-regulating valve;
On the outlet conduit of another surge tank, pressure-regulating valve is installed, and is connected with coke-stove gas methanol device nitrogen header pipe processed, in coke-stove gas methanol device nitrogen header pipe processed, be provided with pressure detector, this pressure detector is connected with pressure-regulating valve;
