Abstract
The utility model provides an improved HCL (Hydrogen Chloride) tail gas absorption device. The improved HCL tail gas absorption device is composed of a mixer, a glycerol absorption tower and a reaction kettle, wherein the mixer is connected with the upper end of the glycerol absorption tower by an input pipeline; the reaction kettle is connected with the bottom end of the glycerol absorption tower by an output pipeline; the reaction kettle is further connected with an HCL conveying pipeline and an overflowing opening; the bottom end of the glycerol absorption tower is further connected with a reflowing pipeline and the top of the glycerol absorption tower is connected with the output pipeline. According to the improved HCL tail gas absorption device, the flow of the glycerol absorption tower is simple, the discharging amount of waste acid water is reduced greatly, the HCL utilization rate is improved and the energy consumption is reduced.
Description
Technical field
The utility model belongs to the chemical industry equipment field, and what be specifically related to is a kind of improved HCL device for absorbing tail gas.
Background technology
at present, in the process of producing at epoxychloropropane, be entrained with organic components in HCL tail gas due to discharge, the absorption plant utilized at present is to adopt clear water absorption tower device, the concentrated acid produced after absorbing with clear water can not enter salt adding and resolve, and can only pass through the alkali neutralisation treatment, thereby cause the waste of alkali resource, reduced the HCL utilization rate, making to prepare the epoxychloropropane production cost increases greatly.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, and a kind of improved HCL device for absorbing tail gas greatly reduced production costs is provided.
The utility model is achieved through the following technical solutions: improved HCL device for absorbing tail gas, by blender, glycerine absorption tower and reactor, formed, described blender is connected with the upper end on glycerine absorption tower by input channel, and reactor is connected with the bottom on glycerine absorption tower by output channel.
Also be connected with HCL conveyance conduit and overfall on described reactor.
The bottom on described glycerine absorption tower also is connected with reflux line, and top is connected with output channel.
The beneficial effects of the utility model embody and are: compared with prior art, the utility model tail gas absorber flow process is simple, greatly reduces the discharge capacity of waste acid water, has improved the HCL utilization rate, has reduced energy consumption.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in detail.
Fig. 1 is the utility model structural representation.
Following is the concrete title of each sign in figure: 1 blender, 2 conveyance conduits, 3 output channels, 4 glycerine absorption towers, 5 HCL conveyance conduits, 6 reflux lines, 7 reactors, 8 input channels, 9 output channels.
The specific embodiment
As shown in Figure 1, improved HCL device for absorbing tail gas, blender 1, glycerine absorption tower 4 and reactor 7, consist of, described blender 1 is connected with the upper end on glycerine absorption tower 4 by input channel 8, and reactor 7 is connected with the bottom on glycerine absorption tower 4 by output channel 9.
Also be connected with HCL conveyance conduit 5 and overfall on described reactor 7.
The bottom on described glycerine absorption tower 4 also is connected with reflux line 6, and top is connected with output channel 3.
The utility model workflow is: after the glycerine outside battery limit (BL) and acetic acid are delivered to that blender 1 is interior and mixed by pump by a certain percentage, enter into glycerine absorption tower 4, mixture absorbs column bottoms pump by glycerine continuously and is transported in reactor 7, and pass into HCL in reactor 7 simultaneously, control material and reacted under suitable temperature and pressure, unnecessary HCL enters in the glycerine absorption tower and absorbs recycling.
