Abstract
The utility model provides a tail water degasser in production of tetrachloroethane, comprising a vacuumized power water tank, wherein a degassing tower is arranged on the vacuumized power water tank; one outlet of the vacuumized power water tank is connected with the inlet of a water pump on the degassing tower through an enamel water absorber; the outlet of the pump on the degassing tower is connected with the inlet of the degassing tower; the other outlet of the vacuumized power water tank is communicated with the inlet of a booster pump through another enamel water absorber; the outlet of the booster pump is connected with the inlet of a water-power jet pump; the outlet of the water-power jet pump is connected with the inlet of a chlorination tail-water tank; the outlet of the chlorination tail-water tank is connected with one inlet of the vacuumized power water tank; and the other inlet of the vacuumized power water tank is connected with the outlet of an alkali liquor storage tank through an alkali liquor delivery pump. As for the tail water degasser, the vacuumized power water can be recycled for a pluralit of times, and the capacity of water to be added is less, thus improving the utilization ratio of water and saving water resource; and the tail water degasser is reasonable in structure, low in electric power, and reduces electrical energy consumption.
Description
Technical field
The utility model provides the device in a kind of tetrachloroethanes production, especially a kind of tail water degasser.
Background technology
At present, the tail water degasser in the tetrachloroethanes production is mainly formed by vacuumizing power pond, pressure pump, hydraulic ejector.During use, running water injected vacuumize the power pond, pressure pump is gone into the waterpower injector with the pressurization of the water in the pond is laggard, extractions such as acetylene excessive in the tail water, chlorine and hydrogen chloride is dissolved in vacuumize in the power water.Vacuumize power water and carry out through after the circulation several times, the pH value of water is more and more lower, and the acetylene gas in the water can't discharge and accumulate, and directly causes site environment abominable, and serious threat is kept the safety in production.Traditional handicraft adopts constantly carries out the problem that method of replacement solves the acetylene gas accumulation in the water with running water to vacuumizing the power pond, and water consumption is bigger.
Summary of the invention
Technical problem to be solved in the utility model is to provide the tail water degasser in a kind of tetrachloroethanes production, to realize vacuumizing the recycling of power water, the utilization ratio of raising water, conserve water resource.
The utility model is to realize like this, tail water degasser during tetrachloroethanes is produced, it vacuumizes the power pond, above vacuumizing the power pond degassing tower is arranged, an outlet that vacuumizes the power pond links to each other through the import of enamel water aspirator with the degassing tower charging pump, the outlet of degassing tower charging pump links to each other with the import of degassing tower, another outlet that vacuumizes the power pond is connected with the import of pressure pump through another enamel water aspirator, the pressure (hydraulic) water delivery side of pump links to each other with the import of hydraulic jet pump, the water-jet delivery side of pump links to each other with the import of chlorination tail tank, the outlet of chlorination tail tank links to each other with an import that vacuumizes the power pond, and another import that vacuumizes the power pond links to each other through the outlet of alkali lye delivery pump with the alkali lye storage tank.
Adopt the tail water degasser of said structure, vacuumizing the trace acetylene gas that contains in the power water is handled clean by degassing tower, guaranteed to vacuumize power water once more circulation time do not contain acetylene gas, vacuumize the alkali lye neutralization that the acid of carrying secretly in the power water and alkali lye delivery pump are sent here, it is neutral that the pH value of water is, but vacuumize power water recycled for multiple times, the water yield that need add is very little, thereby improved the utilization ratio of water, saved water resource, and reasonable in design, electric power is low, has reduced power consumption.
Description of drawings
Fig. 1 is the schematic diagram of the utility model structure.
The specific embodiment
The embodiment that provides below in conjunction with accompanying drawing illustrates concrete structure of the present utility model.
As shown in drawings, tail water degasser during the tetrachloroethanes of the utility model is produced, it vacuumizes power pond 10, vacuumize degassing tower 3 is arranged above the power pond, an outlet that vacuumizes the power pond links to each other through the import of enamel water aspirator 2 with degassing tower charging pump 1, the outlet of degassing tower charging pump links to each other with the import of degassing tower, another outlet that vacuumizes the power pond is connected with the import of pressure pump 5 through another enamel water aspirator 4, the pressure (hydraulic) water delivery side of pump links to each other with the import of hydraulic jet pump 6, the water-jet delivery side of pump links to each other with the import of chlorination tail tank 7, the outlet of chlorination tail tank links to each other with an import that vacuumizes the power pond, and another import that vacuumizes the power pond links to each other through the outlet of alkali lye delivery pump 8 with alkali lye storage tank 9.
During use, the running water injection is vacuumized the power pond, by pressure pump water is delivered to the hydraulic ejector import, contain trace acetylene, the power water that vacuumizes of chlorine and hydrogen chloride enters the chlorination tail tank from hydraulic ejector through pipeline, flow into then and vacuumize the power pond, the solution that contains soda ash simultaneously is delivered to by the alkali lye delivery pump and vacuumizes in the power pond, after the two mixes in vacuumizing the power pond, utilize the degassing tower charging pump to be delivered to the atomizing degassing tower, the trace acetylene that vacuumizes in the power water is separated, also make fully reaction such as soda ash and hydrogen chloride, assurance enters the water that vacuumizes in the power pond and is neutral, and do not contain acetylene, water can use repeatedly, only needs low amounts of water to add displacement.
Described degassing tower can be the atomizing degassing tower.Pressure pump can adopt lining tetrafluoro centrifugal pump.
