Description
Technical Field
The utility model relates to a blast furnace production technical field specifically is a cooling water pipeline system of extension blast furnace tuyere cover life.
Background
The tuyere small sleeve is a consumable part in the production process of the blast furnace, cracks can appear after a period of production, repair is needed, shutdown is needed to replace when the damage is serious, the tuyere small sleeve needs to be continuously introduced with cooling water in the production process to cool the tuyere small sleeve, a cooling water pipeline of the existing tuyere small sleeve of the blast furnace generally adopts 1.6MPa high-pressure soft water as cooling water, and the tuyere small sleeve needs to be immediately shutdown for replacement when cracks appear, so that the production continuity is influenced, and the production efficiency is reduced.
Disclosure of Invention
The utility model aims at providing a cooling water pipeline system for prolonging the service life of a blast furnace tuyere small sleeve in order to solve the problem of the limitation of the service life of the current blast furnace tuyere small sleeve on the production continuity.
The utility model has the following concrete scheme: the utility model provides an extension blast furnace tuyere small sleeve life's cooling water pipe-line system, includes the tuyere small sleeve, and the tuyere small sleeve is equipped with inlet tube and wet return, and cooling water gets into for the tuyere small sleeve cooling back from the return water duct flow to get back to refrigerating system from the inlet tube, a tee bend A is connected to the inlet tube outer end, and inlet tube A and inlet tube B are connected respectively at tee bend A other both ends, are provided with stop valve A and stop valve B on inlet tube A and the inlet tube B respectively, tee bend B is connected to the wet return outer end, and wet return A and wet return B are connected respectively at tee bend B other both ends, are equipped with stop valve C and stop valve D on wet return A and the wet return B respectively.
All be provided with a flow control valve on inlet tube A and the wet return A.
The flow control valve is a butterfly valve.
Stop valve A, stop valve B, stop valve C, stop valve D are ball valves.
The utility model discloses the theory of operation as follows: when the air conditioner normally works, the stop valve B and the stop valve D are closed, the stop valve A and the stop valve C are opened, 1.6MPa high-pressure soft water enters from the water inlet pipe A and flows through the tee joint A and the water inlet pipe of the tuyere small sleeve to enter the tuyere small sleeve for cooling the tuyere small sleeve, then flows out from the water return pipe of the tuyere small sleeve, returns to the refrigerating system through the water return pipe A for cooling, and circularly flows for cooling the tuyere small sleeve; when cracks appear in the tuyere small sleeve along with the production process, the stop valve B and the stop valve D are opened, the stop valve A and the stop valve C are closed, the introduction of high-pressure soft water is stopped, 1.0MPa industrial water flows through the tee joint A from the water inlet pipe B to cool the tuyere small sleeve, and then returns to the refrigerating system from the water return pipe B to flow circularly.
Compared with the prior art, the utility model has the following advantages: 1. when the tuyere small sleeve has cracks, the tuyere small sleeve is continuously cooled by switching low-pressure industrial water, so that the service life of the tuyere small sleeve is prolonged, the furnace shutdown time is shortened, and the production efficiency is improved; 2. the conversion can be completed by controlling the four valves, and the operation is simple and convenient.
