Abstract
The utility model discloses an EO (Ethylene Oxide) and PO (Propylene Oxide) mixing device. The EO and PO mixing device mainly comprises a metering tank and a stainless steel pipeline, wherein the stainless steel pipeline extends to the lower end of the metering tank from the top of the metering tank; a port, extending to the metering tank, of the stainless steel pipeline is closed; the stainless steel pipeline and the metering tank are sealed; a ball valve is connected to the stainless steel pipeline outside the metering tank through a flange; and a plurality of small through holes are uniformly formed in the side wall of the stainless steel pipeline in the metering tank. According to the EO and PO mixing device, nitrogen gas is introduced into the metering tank by using the stainless steel pipeline; meanwhile, the small through holes are formed in the side wall of the stainless steel pipeline in the metering tank, so that the nitrogen gas forms bubbles in an EO and PO mixture; the bubbles drive the flowing of the EO and the PO in the floating process, so that the mutual dissolving of the EO and the PO is accelerated, the EO and the PO are mutually dissolved more uniformly and the stay time of the EO and the PO in the metering tank is shortened; and the reaction quality of products is improved, the structure is reasonably ordered and the quality of products is greatly improved, thereby ensuring the quality stability of downstream products.
Description
Technical field
The utility model relates to surfactant production equipment field, the mixing arrangement of especially a kind of EO and PO.
Background technology
In the prior art; Must mix inflammable and explosive EO and PO when producing atactic polyether; EO and PO successively are pressed into measuring tank and mix the back owing to both chemical molecular character is different; Can not once just can fuse mutually, and both belong to inflammable and explosive character and agitator can't be installed make it to stir and reach both mutual mixed uniformly effects.So need after can only taking to be pressed into to place the long period; But its effect neither be very desirable; The products molecule unreasonable structure that reaction is fluctuateed greatly, produced when causing producing; Product quality is unstable, influences the quality of other relevant downstream product of enterprise thereby lose time again, has caused certain loss to company.
The utility model content
The purpose of the utility model is to provide a kind of for the deficiency that solves above-mentioned technology can inflammable and explosive EO and PO be stirred, EO that acceleration is dissolved each other and the mixing arrangement of PO.
In order to achieve the above object, EO that the utility model designed and the mixing arrangement of PO, it mainly comprises measuring tank and stainless steel pipes; Stainless steel pipes stretches into from the measuring tank top; And extending the measuring tank lower end, stainless steel pipes stretches into the port closed of measuring tank, seals between stainless steel pipes and the measuring tank; On the outside stainless steel pipes of measuring tank, be connected with ball valve, evenly be provided with some small through hole on the sidewall of the stainless steel pipes in measuring tank through flange.This structure utilization: in stainless steel pipes, pour nitrogen; Nitrogen overflows in the small through hole of stainless steel pipes; Form bubble in EO in measuring tank and the mixture of PO, bubble constantly floats, to the mixture stirring of EO and PO; Quicken dissolving each other between the two, be beneficial to the follow-up production and the raising of quality.
The mixing arrangement of resulting EO of the utility model and PO; Utilize stainless steel pipes in measuring tank, to feed nitrogen, be provided with small through hole on the sidewall of the stainless steel pipes in measuring tank simultaneously, make nitrogen in the mixture of EO and PO, form bubble; Bubble drives flowing of EO and PO in floating-upward process; Quicken dissolving each other between the two, and it is more even that both are dissolved each other, and shortened two kinds of times that liquid stops in measuring tank; Improved the reaction mass of product, ordering rational in infrastructure, product quality has greatly improved, thereby has also guaranteed downstream product ground steady quality.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Combine accompanying drawing that the utility model is done further to describe through embodiment below.
Embodiment 1:
As shown in Figure 1, EO that present embodiment is described and the mixing arrangement of PO, it mainly comprises measuring tank 2 and stainless steel pipes 1; Stainless steel pipes 1 stretches into from measuring tank 2 tops; And extending measuring tank 2 lower ends, stainless steel pipes 1 stretches into the port closed of measuring tank 2, sealing between stainless steel pipes 1 and the measuring tank 2; On the stainless steel pipes 1 of measuring tank 2 outsides, be connected with ball valve 4, evenly be provided with some small through hole 5 on the sidewall of the stainless steel pipes 1 in measuring tank 2 through flange 3.
Claims (1)
1. the mixing arrangement of EO and PO; It mainly comprises measuring tank and stainless steel pipes, it is characterized in that stainless steel pipes stretches into from the measuring tank top, and extends the measuring tank lower end; Stainless steel pipes stretches into the port closed of measuring tank; Seal between stainless steel pipes and the measuring tank, on the outside stainless steel pipes of measuring tank, be connected with ball valve, evenly be provided with some small through hole on the sidewall of the stainless steel pipes in measuring tank through flange.
