Abstract
The utility model discloses a kind of to the oil-free reciprocating vacuum pumping system containing sour gas, it is that surge tank, PP caustic treaters, the receiving slit with backing condenser, lobe pump, vavuum pump are sequentially connected, the exhaust outlet of vavuum pump connects condenser, liquid outlet connects solvent receiving tank, the liquid outlet of condenser connects solvent receiving tank, and the utility model has the characteristics of not producing waste water, effective recycling design, pollute small.
Description
Technical field
The utility model belongs to chemical industry technical field of auxiliary equipment, more particularly, to a kind of to the oil-free containing sour gas
Reciprocating vacuum pumping system.
Background technology
In liquid crystal material production process, the process such as its distillation, crystallization, filtering, dry can all use vacuum, while these
There is different degrees of acidity in the gas that process is sucked, and the solvent of intake-gas is needed to reclaim, maximum possible subtracts
Few proportion of goods damageds.At present in liquid crystal material production process in the vacuumizing containing acid material, the vavuum pump used is sprayed with water
Vavuum pump is in the majority, primarily to preventing sour corrosion from causing device damage.But the wastewater flow rate that brings of water stream injection pump it is big and
The shortcoming that solvent is not easily recycled etc., can cause environmental pollution and the waste of cost.
The content of the invention
The purpose of this utility model provides one kind and does not produce waste water, effectively reclaims molten with improving the deficiency of prior art
Agent, pollution are small to the oil-free reciprocating vacuum pumping system containing sour gas.
The purpose of this utility model be achieved in that it is a kind of to the oil-free reciprocating vacuum pumping system containing sour gas,
It is characterized in that surge tank, PP caustic treaters, the receiving slit with backing condenser, lobe pump, vavuum pump are sequentially connected, the row of vavuum pump
Gas port connects condenser, and liquid outlet connects solvent receiving tank, and the liquid outlet of condenser connects solvent receiving tank.
Compared with the prior art the utility model has following distinguishing feature and good effect：The utility model uses oil-free
Vertical piston vacuum pump and Roots's sundstrand pump use, it is to avoid the use of water-jet pump, the oil-free lubrication of excessively stream part, favorably
In the recovery of tail gas, no secondarily polluted water mitigates pollution treatment pressure；Vavuum pump leading portion sets caustic treater and condenser and dump tank,
The acidic materials in gas are absorbed, neutral state is reached, the corrosion to equipment is reduced；The organic solvent of vacuum process is entered
Row is effectively reclaimed, and one is to produce economic benefit；Two be the pollution for reducing uncontrollable discharge, can make the solvent recovery in suction gas
The alkali lye that rate reaches in more than 98%, caustic treater is periodically replaced after the salt inside collection, removing, and water can be recycled again.This
Utility model is effectively treated to sour gas, it is therefore prevented that corrosion of the sour gas to vavuum pump, while also being carried out to solvent
Effective recovery, has saved cost, also avoids the inorganization of solvent from volatilizing the environmental pollution caused.
Brief description of the drawings
Fig. 1 is a kind of structural representation of the present utility model.
Embodiment
It is a kind of to the oil-free reciprocating vacuum pumping system containing sour gas, reference picture 1 is surge tank 1, PP caustic treaters 2, band
Receiving slit 4, lobe pump 5, the air entry of vavuum pump 6 of backing condenser 3 are sequentially connected, and the exhaust outlet of vavuum pump 6 connects condenser
7, liquid outlet connects solvent receiving tank 8, and the liquid outlet of condenser 7 connects solvent receiving tank 8.
