Abstract
The utility model discloses a multi-level jet compressed air evacuating system. The system comprises an air compressor set, wherein an air outlet of the air compressor set is communicated with an air inlet of an air and water separator through a ball valve; an air outlet of the air and water separator is communicated with an air storage tank through a ball valve; an air outlet of the air storage tank is communicated with an air inlet of an air distributor through a pneumatic ball valve; an air outlet of the air distributor is communicated with a work inlet of multiple levels of jet pumps which are connected in series; an air evacuating opening of the first level of jet pump in multiple levels of jet pumps is communicated with a forvacuum tank body; and the forvacuum tank body is communicated with a vacuumized tank body through a pneumatic butterfly valve. The system has the advantages that the structure of the equipment is simple, the whole evacuating system does not have a driving part, and if the connecting place of each connecting flange plate does not loose and leak air, the system is hardly maintained. Meanwhile, the energy consumption is low, the evacuating efficiency is high, and the operation and maintenance cost of the evacuating system is greatly reduced.
Description
Technical field
The utility model relates to pumped vacuum systems, especially relates to multi-stage jet pressurized air evacuation system.
Background technique
Pumped vacuum systems is widely used in the fields such as industry, medicine, tobacco.At present, pumped vacuum systems mainly contains following two kinds of forms: 1, pressure decatizing vapour sprays and vacuumizes unit; This vacuumizes unit from use angle, and shortcoming one is maintenance expense higher (care and maintenance that mainly refers to the steam boiler facility is used artificial cost of labor), and the 2nd, it is excessive to consume steam flow.2, continous way water jet steam/water series connection vacuumizes unit; Shortcoming mainly is that water circulation Jet injector mechanical wear is large after using 6-8 month, poor performance, and the sealing of water circulation Jet injector transmission position causes dew easily, does not reach index request if untimely replacing accessory and maintenance will cause to vacuumize; Simultaneously, mechanical transmission component is many, and steam consumption is excessive.
Summary of the invention
The utility model purpose is to provide a kind of manufacturing, operation, multi-stage jet pressurized air evacuation system that maintenance cost is low.
For achieving the above object, the utility model is taked following technical proposals:
Multi-stage jet pressurized air evacuation system described in the utility model comprises the pressurized air unit; Described pressurized air unit air outlet is communicated with the moisture trap suction port by ball valve; Described moisture trap air outlet is communicated with air storage tank by ball valve; Described air storage tank air outlet is communicated with the air distributor suction port by pneumatic ball valve; Described air distributor air outlet is communicated with the work import of the multistage jet pump that is in series, and the bleeding point of the first order jet pump in the described multistage jet pump is communicated with the forvacuum tank body; Described forvacuum tank body by Pneumatic butterfly valve be evacuated tank body and be communicated with.
The described jet pump that is in series is Pyatyi; The work import of first, second, third and fourth grade jet pump is communicated with by a pneumatic ball valve air outlet corresponding with described air distributor respectively; The diffusing tube outlet of first order jet pump is communicated with the bleeding point of second level jet pump, the diffusing tube outlet of second level jet pump is communicated with the bleeding point of third level jet pump, the diffusing tube outlet of third level jet pump is communicated with, is communicated with by the bleeding point of one-way valve with the level V jet pump with fourth stage jet pump bleeding point by pipeline respectively, and is communicated with the bleeding point of accelerating pump by pipeline; Described accelerating pump suction port is communicated with by a pneumatic ball valve air outlet corresponding with air distributor; The diffusing tube outlet of fourth stage jet pump, accelerating pump is communicated with Sound Attenuator; The work import of level V jet pump is communicated with the circulating water pump water outlet by trimmer valve, and described circulating water pump water intake is communicated with cyclic water tank by valve, and the diffusing tube outlet of level V jet pump is communicated with described cyclic water tank.
Be respectively arranged with the hydrophobic dirt-removing valve in the bottom of described moisture trap, air storage tank, air distributor, cyclic water tank.
The utility model advantage is simple in equipment, and whole evacuation system does not have transmission part, as long as each mounting flange joint is not loosening, air tight on the pipeline, does not almost have amount of maintenance.Simultaneously energy consumption is few, vacuumizes the efficient height, greatly reduces operation, the maintenance cost of pumped vacuum systems.
