Description

A horizontal dry desulfurization device

technical field

The utility model relates to the technical field of coal gas desulfurization, in particular to a horizontal dry desulfurization device.

Background technique

Most of the sulfur in the gas exists in the form of H ₂ S, and H ₂ S is converted into SO ₂ after the gas is burned. If the SO ₂ content in the air exceeds the standard, local acid rain will be formed, which will endanger people's living environment; on the other hand , H ₂ S in the gas will also corrode equipment and pipelines, affecting the normal operation of the process system. Therefore, the removal degree of H ₂ S in gas has become an important indicator of its cleanliness.

There are two types of gas desulfurization: dry method and wet method. Dry desulfurization is a traditional gas desulfurization process. Its process is simple. In addition to removing H ₂ S, it can also remove HCN, NOx, naphthalene and tar mist to varying degrees. and other impurities. At present, the main desulfurization equipment commonly used in the dry desulfurization process includes dry box desulfurization devices, fixed bed dry desulfurization towers, seven-basket dry desulfurization towers, etc. The structure of these types of desulfurization equipment is relatively complex, and it is difficult to replace the dry desulfurization agent and the labor intensity is high, which has great limitations in engineering applications; at the same time, due to the increasing gas processing capacity of dry desulfurization, multiple units are often required The above-mentioned equipment cannot meet the requirements of large-scale combination of equipment.

The Chinese utility model patent whose authorized notification number is CN 203833904 U discloses a "dry desulfurization device suitable for producer gas", which includes a cylinder with an open top, a diffuser cover at the opening of the cylinder, And the support frame arranged in the cylinder body layer by layer, the desulfurizer is placed in the support frame, and there is a gas channel between the upper and lower adjacent layers of desulfurizer; the gas channel is formed on the side wall of the cylinder body. Inlet and gas outlet, the gas inlet and gas outlet are distributed at both ends of the cylinder diameter; cylinder bosses for placing support frames are also formed on the side walls of the cylinder. In this device, the gas inlet and the gas outlet are set opposite to each other on both sides of the cylinder. Although there are multiple layers of desulfurizers, the gas easily flows through the shortest path from the gas inlet to the gas outlet, and the purpose of desulfurization cannot be achieved; In addition, there is a gas channel between each layer of desulfurizer, but it is foreseeable that after the gas enters the device, the amount of gas flowing upward or downward from the layer where the gas inlet-gas outlet is located gradually decreases, so the utilization rate of the equipment is low. The desulfurization effect is difficult to guarantee.

In order to overcome the shortcomings of the existing technology, it is necessary to develop a new type of dry desulfurization equipment, which should have the functions of convenient replacement of desulfurization agent, simple sealing structure, good equipment versatility, and suitable for large-scale desulfurization device applications.
