Abstract
The utility model discloses a diluted hydrochloric acid recovering device, which includes a reaction kettle, wherein a hydrochloric acid gas outlet on the reaction kettle is connected with a spray tower through a pipeline, a liquid outlet of the spray tower leads to a diluted hydrochloric acid storage tank, and a backflow spray pipeline is arranged between the diluted hydrochloric acid storage tank and the spray tower. The utility model adopts the backflow arrangement, can improve precision and purity of the diluted hydrochloric acid, reduces the gas leakage, improves the raw material utilization rate, and increases the production efficiency of an enterprise.
Description
Technical field
The utility model belongs to a kind of retrieving arrangement, specifically is a kind of dilute hydrochloric acid retrieving arrangement.
Background technology
In the existing dilute hydrochloric acid production process, the still-process that uses is generally direct rectifying, the reactant that steaming is boiled ejects from spray column at a certain temperature, contain certain impurity, precision and purity are all not enough, have influenced quality product, and gas leak is more, raw material availability is not high, forms waste, has increased enterprise's production cost.
The utility model content
The purpose of this utility model provides a kind of dilute hydrochloric acid retrieving arrangement, can reduce gas leak, improves product precision and purity, increases enterprise's productivity effect.
The technical solution of the utility model is as follows:
A kind of dilute hydrochloric acid retrieving arrangement, include reactor, the hydrochloric acid pneumatic outlet is connected to spray column by pipeline on the described reactor, and the material liquid outlet of described spray column leads to the dilute hydrochloric acid storage tank, is provided with the backflow spray piping between described dilute hydrochloric acid storage tank and the spray column.
The utility model has adopted the setting that refluxes, the gas that steams is through behind the spray column, portion gas has run away, also have part to get back to again in the original reactor, reduced gas leak, and the reactant that the process steaming is boiled is through twice spray column, impurity separates twice, thereby improved precision and purity, improved raw material availability, increased enterprise's productivity effect.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
A kind of dilute hydrochloric acid retrieving arrangement, include reactor 1, the hydrochloric acid pneumatic outlet is connected to spray column 2 by pipeline on the described reactor 1, and the material liquid outlet of described spray column 2 leads to dilute hydrochloric acid storage tank 3, is provided with backflow spray piping 4 between described dilute hydrochloric acid storage tank 3 and the spray column 2.
Claims (1)
1. dilute hydrochloric acid retrieving arrangement, include reactor, the hydrochloric acid pneumatic outlet is connected to spray column by pipeline on the described reactor, and the material liquid outlet of described spray column leads to the dilute hydrochloric acid storage tank, is provided with the backflow spray piping between described dilute hydrochloric acid storage tank and the spray column.
