Steam sucking and cooling system for turbine steam seal for sugar factory

The utility model provides a steam sucking and cooling system for a turbine steam seal for a sugar factor. The steam sucking and cooling system mainly comprises a cooling water tank, cooling water, a coiled heat exchange tube and a steam chamber, wherein the cooling water tank is an enclosed water tank filled with the cooling water; the coiled heat exchange tube is distributed in the tank; one side of the cooling water tank is provided with the steam chamber; the steam chamber receives high temperature steam leaked by the turbine steam seal through a pipeline; the inlet of the coiled heat exchange tube is communicated with the steam chamber. During use, high temperature steam in the coiled heat exchange tube is cooled by the cooling water to form negative pressure vacuum, and the leaked steam of the turbine steam seal is automatically sucked to the steam chamber. By adopting the system, the leaked steam of the turbine steam seal is sucked and cooled, new high-pressure steam is not required to be added, and th
