Description

A kind of New ring vacuum pump system
Technical field
The utility model relates to a kind of vacuum pump system, is specifically related to a kind of New ring vacuum pump system.
Background technique
Chemical plant installations often adopts Nash hytor to obtain vacuum, this process system mainly from the equipment of required vacuum connecting tube to vacuum pump, separately provide circulating water to vacuum pump, utilize the centrifugal drive gas phase of circulating water, produce vacuum.The air-water mixture of discharging from vacuum pump is through gas water separation tank, and gas is to tail gas adsorption system, and the circulating water polluted by process gas is to sewage-treatment plant.
The shortcoming of existing water ring vacuum system is: 1, quantity of circulating water consumption is large, increases device utility cost; 2, the circulating water polluted by process gas after air-water separation through waste water treatment, need increase device waste water treatment expense; 3, be dissolved in process stream in circulating water and be not recovered utilization, increase process stream consume.
Model utility content
The purpose of this utility model is: provide a kind of environmental protection, New ring vacuum pump system that cost is low.
To achieve these goals, the utility model provides following technological scheme:
A kind of New ring vacuum pump system, comprise vacuum equipment, liquid-ring vacuum pump, gas-liquid separation groove, condenser, high position tank, tail gas absorbing system, described high position tank is disposed with flow-off, refluxing opening, liquid entering hole from top to bottom;
Described vacuum equipment is connected with the intakeport of liquid-ring vacuum pump by vacuum gas-phase pipe, and the vapor-liquid outlet of liquid-ring vacuum pump is connected with the import of gas-liquid separation groove, and the air outlet of gas-liquid separation groove is connected with tail gas absorbing system;
Process liquid in process system enters in gas-liquid separation groove by pipeline, liquid after gas-liquid separation groove is separated enters into high position tank through recycle pump, condenser successively, the flow-off of described high position tank is connected with process system, the refluxing opening of high position tank is connected with gas-liquid separation groove, and the liquid outlet of high position tank is connected with the liquid entering hole of liquid-ring vacuum pump.
Preferably, the air outlet of described gas-liquid separation groove is arranged on the top of groove.
Preferably, between the flow-off of described high position tank and process system, switch valve is set.
The beneficial effects of the utility model are:
1, process liquid material replaces circulating water, reduces device utility cost.2, process liquid material replaces circulating water, avoids waste water to produce, and reduces waste water treatment expense.3, process liquid material absorption technique vacuum gas, reduces pollution of atmosphere, recovery process material.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
1 the utility model is described in further detail by reference to the accompanying drawings:
A kind of New ring vacuum pump system, comprise vacuum equipment 1, liquid-ring vacuum pump 2, gas-liquid separation groove 3, condenser 4, high position tank 5, tail gas absorbing system 6, described high position tank 5 is disposed with flow-off, refluxing opening, liquid entering hole from top to bottom;
Described vacuum equipment 1 is connected by the intakeport of vacuum gas-phase pipe with liquid-ring vacuum pump 2, and the vapor-liquid outlet of liquid-ring vacuum pump 2 is connected with the import of gas-liquid separation groove 3, and the air outlet of gas-liquid separation groove 3 is connected with tail gas absorbing system 6;
Process liquid in process system 7 enters in gas-liquid separation groove 3 by pipeline, liquid after gas-liquid separation groove 3 is separated enters into high position tank 5 through recycle pump 8, condenser 4 successively, the flow-off of described high position tank 5 is connected with process system 7, the refluxing opening of high position tank 5 is connected with gas-liquid separation groove 3, and the liquid outlet of high position tank 5 is connected with the liquid entering hole of liquid-ring vacuum pump 2.
The air outlet of described gas-liquid separation groove 3 is arranged on the top of groove.
Between the flow-off of described high position tank 5 and process system 7, switch valve is set.
Working principle of the present utility model: be connected to liquid-ring vacuum pump 2 by vacuum gas-phase pipe from the process gas of vacuum equipment 1, gas-liquid mixed is from the vapor-liquid outlet of liquid-ring vacuum pump 2 to gas-liquid separation groove 3, and gas phase is from gas-liquid separation groove 3 top to tail gas adsorption system 6.Liquid phase after recycle pump 8, condenser 4 to liquid high position tank 5.A high position tank 5 liquid level high position arranges flow-off, and pipeline arranges switch valve and returns process system 7, when the liquid level of gas-liquid separation groove 3 reaches high limit, switch valve is opened by off status, process liquid flows to process system 7, and gas-liquid separation groove 3 liquid level returns normal envelope, and switch valve cuts out.A high position tank 5 liquid level time high position arranges refluxing opening, process liquid return-air liquid separating vessel 3.High position tank 5 liquid level low level arranges liquid outlet, to liquid-ring vacuum pump 2, replaces circulating water, absorbs vacuum gas, do not produce wastewater flow rate.The process liquid of absorption technique gas, to process system, reduces discharge of materials, environment protection, recovery process material.
Above-mentionedly by reference to the accompanying drawings model utility to be exemplarily described; obvious the utility model specific implementation is not subject to the restrictions described above; as long as this insubstantial that the method that have employed model utility is conceived and technological scheme is carried out is improved; or the design of model utility and technological scheme directly applied to other occasions, all within protection domain of the present utility model without to improve.
