Briefly describe the working principle of high pressure Mann gas holder

Working principle of high pressure Mann gas holder
High-pressure Mann-type gas holder automatically operates with the gas throughput and automatically balances the pressure of the gas pipe network. When the gas in the gas pipe network increases and the pressure of the gas pipe network is higher than the working pressure of the gas holder, the gas enters the gas holder and pushes the piston up; When the gas in the gas pipe network is reduced and the pressure of the gas pipe network is lower than the working pressure of the gas holder, the piston will lower to send the gas into the pipe network, which will stabilize the pressure of the pipe network and reduce the emission, which is conducive to the stable combustion of the gas user and improve the thermal system of the user.
3.2 Advantages and functions of high-pressure Mann gas holder
At the initial stage of the construction of the gasholder, steel enterprises should determine the working pressure and design pressure of the gasholder according to the pressure system and demand of users and the pressure system of the pipe network. The actual application of the high pressure cabinet can greatly reduce or save the electric energy consumption and live or physical labor during gas pressurization, and save energy and consumption. The operation mode of high-pressure Mann gas holder is as follows:
The high-pressure Mann type gas holder is generally equipped with an inlet and outlet main pipe, which is connected in parallel with the main gas network. When one or more gas users stop production for maintenance, the gas holder piston rises to absorb the excess gas in the pipe network, reducing or avoiding the gas emission; When the gas source plant, such as the blast furnace, is shut down for maintenance or the hot blast furnace is reversed, the gap in the user's production is "spewed" from the gas holder to the main gas network for the user's use, reducing or avoiding the impact on the user's production. In this way, iron and steel enterprises can use the storage, transportation and hedging capacity of high-pressure gas holders to significantly reduce gas emission, fill valley and cut peak, use surplus to make up for deficiency, and recycle and absorb gas emission when production is unbalanced.
