Abstract
The utility model relates to a formic acid recovery device for calcium formate reaction tail gas, which comprises a reactor, an absorption column and a vacuum pump, and is characterized in that: the formic acid recovery device also comprises a return pipe, wherein the tail gas exhaust port of the reactor is connected with the gas inlet of the absorption column by a pipeline, the lower end of the absorption column is connected with a circulating pump by a pipeline, the circulating pump is connected with the upper end of the absorption column by a pipeline, the lower end of the absorption column is connected with the return pipe by a pipeline, and the return pipe is connected with the reactor by a pipeline. As the return pipe is additionally arranged on the formic acid recovery device, workers have no need to continuously detect the data during the absorption process, the absorption liquid during the absorption process of absorption liquid can automatically flow back to the reactor, the workers have no need to continuously add water after the absorption liquid is discharged each time, the energy consumption is reduced and the use equipment is reduced.
Description
Technical field
The utility model relates to formic acid retracting device in a kind of calcium formate tail gas, belongs to the chemical industry equipment field.
Background technology
In existing technology, one is finished the device for absorbing tail gas of chemical industry by separation and absorption plant, especially in the production process of calcium formate, absorption need add water in the absorption plant, and needs personnel to control, it is lower to reclaim concentration, being back to produce to evaporate then needs to consume a large amount of energy again again, causes energy waste, and in absorption process, need personnel to detect at any time, also moisturizing in time when at every turn emitting absorption liquid.
This has not only caused the waste on the personnel, has also increased the waste of water resource and the waste of the energy.
Summary of the invention
According to the deficiencies in the prior art, the technical problems to be solved in the utility model is: formic acid retracting device in a kind of calcium formate tail gas is provided, detects data at any time without personnel, need not add water constantly, reduced energy resource consumption.
The technical scheme that its technical problem that solves the utility model adopts is: formic acid retracting device in a kind of calcium formate tail gas is provided, comprise reactor, absorption tower and vavuum pump, it is characterized in that also comprising: return duct, the exhaust port of reactor connects the air inlet on absorption tower by pipeline, the lower end on absorption tower connects vavuum pump by management, vavuum pump is connected to the upper end, absorption tower by pipeline, and the lower end, absorption tower connects return duct by pipeline, and return duct is by pipeline coupled reaction still.
The connector on described return duct and absorption tower is higher than the connector on vavuum pump and absorption tower.
The beneficial effects of the utility model are: by installing additional of return duct, can be so that in the absorption process, need not the workman and constantly detect data, after acquiring a certain degree, absorption liquid can be back to automatically in the reactor, constantly add water after need not emitting absorption liquid at every turn, reduced the consumption of the energy, use equipment reduces.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1 is reactor; 2 is the absorption tower; 3 is vavuum pump; 4 is return duct;
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
As shown in Figure 1, the utility model comprises reactor 1, absorption tower 2, vavuum pump 3 and return duct 4, the exhaust port of reactor 1 connects the air inlet on absorption tower 2 by pipeline, the lower end on absorption tower 2 connects vavuum pump 3 by management, vavuum pump 3 is connected to 2 upper ends, absorption tower by pipeline, 2 lower ends, absorption tower connect return duct 4 by pipeline, and return duct 4 is by pipeline coupled reaction still 1.
The connector on return duct 4 and absorption tower 2 is higher than the connector on vavuum pump 3 and absorption tower 2.
During use, at first in absorption tower 2, add an amount of water, as lyosoption, reaction end gas in the reactor 1 enters into absorption tower 2 by pipeline then, under the effect of vavuum pump 3, the water of 2 bottoms, absorption tower is extracted into 2 tops, absorption tower, water falls back to 2 bottoms, absorption tower after absorbing tail gas, and when the page in the absorption tower 2 reached the height on return duct 4 connection absorption towers 1, absorption liquid will be back in the reactor 1 under the effect of gravity automatically.
