Abstract
The invention discloses a methanol recovery treatment system which is characterized by comprising a preheater (1), a recovery tower (2), a reboiler (3) and a condenser (4), wherein the recovery tower (2) is respectively communicated with the preheater (1), reboiler (3) and condenser (4) through a pipeline; and the raw material is preheated by the preheater (1), delivered to the recovery tower (2), treated by the recovery tower (2) and delivered to the reboiler (3) to obtain methanol-containing steam, and the methanol-containing steam is recovered by the recovery tower (2), sent to the condenser (4) and condensed to obtain the recovered methanol. The raw material is subjected to circular treatment between the recovery tower and reboiler, so that the methanol in the raw material is sufficiently recovered, and part of heat generated by the reboiler is transferred to the preheater for reutilization via the recovery tower. The system has the characteristics of low cost, high efficiency and higher energy utilization efficiency, and is suitable for popularization and application.
Description
Technical field
The present invention relates to a kind of Methanol Recovery treatment system.
Background technology
In painting industry, containing a certain amount of methyl alcohol in used waste material, owing to there is no low cost, high efficiency recycling equipment, this part methyl alcohol is generally gone out of use, is unfavorable for the construction of economical and environment-friendly society.
Summary of the invention
The object of the invention is for prior art Problems existing, provide a kind of can recycle energy, reduce costs and the higher Methanol Recovery treatment system of efficiency.
The object of the invention is to solve by the following technical programs:
A kind of Methanol Recovery treatment system, it is characterized in that: described recovery and processing system comprises preheater, recovery tower, reboiler and condenser, recovery tower is connected with condenser with preheater, reboiler respectively by pipeline, its Raw is delivered to recovery tower after preheater preheats, after recovery tower process, be delivered to reboiler obtain containing the steam of methyl alcohol, and then after recovery tower recycling, be sent to the methyl alcohol that namely condenser condenses be recycled.
Described reboiler is connected with bottom with the bottom of recovery tower respectively by pipeline, makes reboiler will to be sprayed onto the bottom of recovery tower containing the steam of methyl alcohol the feedstock transportation after initial treatment to make recovery tower by the pipeline bottom it to reboiler.
Described preheater is connected with the middle and upper part of recovery tower respectively by pipeline.
The pipeline that is connected with preheater is provided with to be supplied to preheater for raw material preheating the waste water containing certain heat at the bottom of the tower of described recovery tower.
The present invention has the following advantages compared to existing technology:
The present invention passes through preheater, recovery tower, being interconnected between reboiler and condenser, construct the recovery and processing system of methyl alcohol, this system is by the circular treatment of raw material between recovery tower and reboiler, methyl alcohol in raw material is fully reclaimed, and the partial heat that reboiler produces also sends preheater recycling to by recovery tower, said system has the advantages that cost is low, efficiency is high and improve capacity usage ratio, is suitable for promoting the use of.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present invention.
Wherein: 1-preheater; 2-recovery tower; 3-reboiler; 4-condenser.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the present invention is further illustrated.
As shown in Figure 1: a kind of Methanol Recovery treatment system, this recovery and processing system comprises preheater 1, recovery tower 2, reboiler 3 and condenser 4, recovery tower 2 is connected with condenser 4 with preheater 1, reboiler 3 respectively by pipeline, its Raw is delivered to recovery tower 2 after preheater 1 preheating, after recovery tower 2 processes, be delivered to reboiler 3 obtain containing the steam of methyl alcohol, and then after recovery tower 2 recycles, be sent to the methyl alcohol that namely condenser 4 condensation be recycled.Specifically, reboiler 3 is connected with bottom with the bottom of recovery tower 2 respectively by pipeline, makes reboiler 3 will to be sprayed onto the bottom of recovery tower 2 containing the steam of methyl alcohol the feedstock transportation after initial treatment to make recovery tower 2 by the pipeline bottom it to reboiler 3; Simultaneously preheater 1 is connected to provide the starting material through preheating with the middle and upper part of recovery tower 2 respectively by pipeline, is provided with the pipeline that is connected with preheater 1 to be supplied to preheater 1 for raw material preheating the waste water containing certain heat at the bottom of the tower of recovery tower 2.
The present invention passes through preheater 1, recovery tower 2, being interconnected between reboiler 3 and condenser 4, construct the recovery and processing system of methyl alcohol, this system is by the circular treatment of raw material between recovery tower 2 and reboiler 3, methyl alcohol in raw material is fully reclaimed, and the partial heat that reboiler 3 produces also sends preheater 1 to by recovery tower 2 and recycles, said system has the advantages that cost is low, efficiency is high and improve capacity usage ratio, is suitable for promoting the use of.
Above embodiment is only and technological thought of the present invention is described, can not limit protection scope of the present invention with this, every technological thought proposed according to the present invention, and any change that technical scheme basis is done, all falls within scope; The technology that the present invention does not relate to all is realized by prior art.
