Embodiment Construction

[0018] The structural principle and working principle of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0019] Such as figure 1 Shown: a vacuum pump system configuration model of a combination of water ring pump and steam pump, including B1 booster pump 1, B2 booster pump 2, B3 booster pump 3, C1 condenser 4 and water ring pump unit, B1 booster Pump 1, B2 booster pump 2, and B3 booster pump 3 are connected in series through the air extraction pipeline. The inlet of B1 booster pump 1 is connected with the waste gas generated in the steelmaking process, and the outlet of B3 booster pump 3 is connected with C1 Condenser 4 Unicom. A suction pipe is connected from the top of the C1 condenser 4 and connected to two parallel water ring pump units. The exhaust ports of each water ring pump are converged and connected to an exhaust pipe, and then communicated with the exhaust gas outlet. Corresponding control valves are set o...

Abstract

The invention discloses a vacuum pump system combining three stages of booster pumps and water ring pumps. The vacuum pump system comprises a booster pump B1 communicating to a waste gas generating position, and an output end of the booster pump B1 is sequentially connected with a booster pump B2, a booster pump C3, a condenser C1 and water ring pump units; exhaust ports of the water ring pumps ofwater ring pump units are connected with waste gas outlets, and the water ring pump units are W4 water ring pump units; after working modes of the water ring pumps are selected and confirmed, a vacuum system is started; and all stages of vacuum pumps are started and stopped according to preset vacuum pressure values until a vacuum degree required by a process is met. The vacuum pump system has the characteristics of meeting requirements of the refining process and high efficiency and energy conservation.

Description

technical field [0001] The invention relates to the technical field of vacuum refining outside a molten steel furnace, in particular to a vacuum pump system combined with a three-stage booster pump and a water ring pump. Background technique [0002] The core equipment of the molten steel vacuum refining system is vacuum obtaining equipment, and the traditional vacuum obtaining equipment used in the molten steel vacuum refining system is a steam jet vacuum pump. Steam jet pumps are characterized by large pumping capacity, fast pumping speed, and low maintenance costs, but their disadvantages are high energy consumption and strict requirements on steam quality, which affect production and operation costs. In recent years, there are also many application examples of vacuum obtaining equipment combining water ring pumps and steam pumps. In the unit composed of the steam jet pump and the water ring pump, the water ring pump is the backing pump for exhausting the atmosphere. If...
