Embodiment Construction

[0038] figure 1 A structural diagram of a concentrated solution diluting device according to an embodiment of the present invention is shown. refer to figure 1 As shown, the concentrated solution dilution device 10 may include a first storage tank 11, a rotor pump 12, a frequency converter 13, a dilution pipeline 14, a flow meter 15, a flow regulating valve 16, a homogeneous mixing pump 17, a contactor 19 and a control device 20. The first storage tank 11 is used to store the solution to be diluted, such as AES commonly used in the daily chemical industry. This solution is usually a higher concentration, for example up to 75% concentrated solution. The capacity of the first storage tank 11 can reach 1.5T.

[0039] The rotor pump 12 is connected to the first storage tank 11 through a pipeline. The frequency converter 13 is electrically connected to the rotor pump 12 . The frequency converter 13 outputs a frequency signal to the rotor pump 12 according to a first flow sign...

Abstract

The invention relates to a device for diluting a concentrated solution and a method. The device mainly comprises a first storage tank, a rotor pump, a frequency converter, a diluting pipeline, a flowmeter, a flow regulating valve, a homogenizing mixing pump and a controller. The frequency converter is electrically connected to the rotor pump and outputs a first frequency signal to the rotor pump according to a first flow signal so as to control the rotation speed of the rotor pump, thus controlling the flow of the concentrated solution. The flowmeter is arranged on the diluting pipeline and outputs a flow detection signal. The flow regulating valve is arranged on the diluting pipeline and regulates the opening degree of the valve according to the flow detection signal and a second flow signal so as to control the solvent flow of the diluting pipeline. The homogenizing mixing pump is provided with a first input port, a second input port and an output port. The first input port is connected to the rotor pump through a pipeline. The second input port is connected to the diluting pipeline. The controller is connected to the frequency converter and the flow regulating valve and outputs the first flow signal and the second flow signal, wherein the second flow signal is determined according to the first flow signal.

Description

technical field [0001] The invention relates to the production field of daily chemical products, in particular to a concentrated solution dilution device and method. Background technique [0002] In the daily chemical industry, due to the consideration of transportation costs and the stability of raw materials, manufacturers will directly purchase high-concentration raw material solutions from outside, and then dilute the high-concentration raw material solutions in the factory to be directly in the Low-concentration raw materials used in production. Taking AES (sodium fatty alcohol polyoxyethylene ether sulfate, also known as ethoxylated alkyl sodium sulfate) raw material as an example, 25% AES solution is a kind of surfactant, which is a bulk raw material in the shampoo industry . Under normal circumstances, daily chemical production enterprises need to dilute the purchased 70% concentration of AES to 25% concentration and then use it as a raw material for production. ...
