Description

Technical Field

[0001] This utility model relates to the field of gas mixing and storage technology, specifically a carbon monoxide and hydrogen mixed gas buffer distribution tank. Background Technology

[0002] During the storage or transportation of carbon monoxide and hydrogen mixed gas, the internal pressure of the gas mixture can change due to temperature variations and the relatively small molar mass of the gases. These pressure fluctuations directly affect the safety of storage and transportation. Using a buffer tank allows the buffer gas inside to appropriately absorb or release pressure, controlling the pressure changes of the mixed gas within a certain range, thereby ensuring the safety of storage and transportation.

[0003] Hydrogen (H2): Has an extremely wide explosion limit (4%-75%) and an extremely low ignition energy (0.02 mJ), making it highly flammable and prone to explosion. Carbon monoxide (CO): Also a flammable gas (explosion limit 12.5%-74%). Mixtures of these two gases present a compounded explosion hazard, and the explosion limit range varies depending on their proportions. Any leak reaching the explosion limit will trigger a violent explosion upon encountering an ignition source (static electricity, sparks, high-temperature surfaces, etc.). Therefore, stability is a crucial factor for buffer distribution tanks, and existing buffer distribution tanks have a short service life.

[0004] Therefore, a carbon monoxide and hydrogen mixed gas buffer distribution tank was designed based on the above technical problems. Utility Model Content

[0005] To address the problems of short service life and poor safety and stability of current buffer distribution tanks, this utility model proposes a buffer distribution tank for a mixture of carbon monoxide and hydrogen.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a carbon monoxide and hydrogen mixed gas buffer distribution tank, including a tank body, an inlet and an outlet. The inner part of the tank body is divided into a storage tank and a distribution tank. A tank partition is provided between the storage tank and the distribution tank. The tank body includes an inner liner layer, a middle layer and an outer layer from the inside to the outside. A solenoid valve switch is provided on the tank partition. The solenoid valve switch is used to connect and close the storage tank and the distribution tank. The inlet is connected to the storage tank and the outlet is connected to the distribution tank.

[0007] Working principle: This application adopts a dual-chamber structure, namely a storage tank and a distribution tank. The storage tank and the distribution tank are connected and isolated by a solenoid valve switch. When the storage tank is operating normally, the two chambers are isolated. When pressure fluctuations occur in the storage tank, the distribution chamber is opened to regulate the pressure in the two chambers, thus avoiding the influence of pressure fluctuations in the storage chamber on the distribution accuracy. At the same time, the tank body has a three-layer structure, which increases the stability of the overall tank structure. The air inlet is connected to the storage tank, and the air outlet is connected to the distribution tank, which can effectively avoid leakage problems caused by frequent opening and closing of the storage tank.

[0008] Preferably, the tank partition is equipped with a Venturi multi-pipe distributor, which connects the storage tank and the distribution tank. The battery valve switch is located on the Venturi multi-pipe distributor, which can directly mix fluids of different pressures and optimize the distribution accuracy through fluid dynamics.

[0009] Preferably, the tank is equipped with a safety valve at the top, a pressure gauge at the bottom, and a drain outlet with a valve at the bottom.

[0010] Preferably, the air inlet is connected to the air inlet pipe, an air inlet valve is provided between the air inlet and the air inlet pipe, the air outlet is connected to the air outlet pipe, an air outlet valve is provided between the air outlet and the air outlet pipe, an air inlet pressure gauge is provided on the air inlet pipe, and an air outlet pressure gauge is provided on the air outlet pipe.

[0011] Preferably, the air outlet has one or more outlets.

[0012] Preferably, the inner liner is made of 316L stainless steel, which is a hydrogen embrittlement resistant substrate.

[0013] Preferably, the intermediate layer is a nano-ceramic coating, which is formed into a dense hydrogen barrier layer by vapor deposition technology, reducing hydrogen permeability by >90%.

[0014] Preferably, the outer layer is a carbon fiber reinforced composite material, wound with high-tensile carbon fiber tape to achieve lightweight and crack resistance.

[0015] Preferably, the tank body is provided with a base at the bottom, and the bottom of the tank body has an arc-shaped structure to prevent sewage and other substances from accumulating at the bottom of the tank body.

[0016] Preferably, the storage tank occupies 70%-80% of the overall tank volume, effectively relieving the pressure in the storage tank without affecting its volume.

[0017] The advantages of this utility model are:

[0018] This utility model features a dual-chamber design, consisting of a storage tank and a distribution tank. When the storage tank is operating normally, the two chambers are isolated. When pressure fluctuations occur in the storage tank, the distribution chamber is opened to regulate the pressure in both chambers, thus preventing the distribution accuracy from being affected by pressure fluctuations in the storage tank. Furthermore, the tank has a three-layer structure, which increases the overall stability and safety of the tank.

[0019] 2. The tank body of this utility model adopts a three-layer composite structure, which simultaneously solves the problems of hydrogen embrittlement, corrosion and mechanical strength, and greatly extends the service life of the tank body.

[0020] 3. This utility model is equipped with a Venturi multi-pipe distributor, which connects the storage tank and the distribution tank. The battery valve switch is set on the Venturi multi-pipe distributor. The Venturi multi-pipe distributor can directly mix fluids of different pressures and optimize the distribution accuracy through fluid dynamics. Attached Figure Description
