Summary of the invention
The utility model provides a kind of recycling thermal water resource at background technology, using water wisely, and increase the oxidation of ethanol reaction unit of safe filter at the input of alcohol steam.
The utility model is realized by following technical measures: a kind of oxidation of ethanol reaction unit, comprise oxidation furnace, the oxidation furnace upper end is provided with material inlet, is provided with the two sections heat exchanger in the oxidation furnace, and the upper and lower heat exchanger of oxidation furnace connects the hot water heat-exchanger rig that hot water circuit is used successively.
Concrete, the epimere heat exchanger comprises epimere hot water inlet and epimere hot water outlet, the hypomere heat exchanger comprises hypomere hot water inlet and hypomere hot water outlet.
As optimized technical scheme, above-mentioned hot water heat-exchanger rig comprises hot-water cylinder, heat-exchanger pump and the Re Bao that connects successively; Heat-exchanger pump is connected with the hypomere hot water inlet by pipeline, and the hypomere delivery port is connected with Re Bao.
In order to make the heat exchange needs of epimere heat exchanger, further feature of the present utility model has, and above-mentioned epimere hot water inlet is connected the heat bag with the epimere hot water outlet, and heat is wrapped and is provided with discharge outlet; Heat-exchanger pump is connected with Re Bao.
For the purity of the material that guarantees to enter oxidation furnace and the security that improves equipment, further feature of the present utility model has, and above-mentioned material inlet is connected with the filtration spark arrester.
For the output of material and the recycling of raw material, further feature of the present utility model also has, and above-mentioned oxidation furnace bottom is provided with discharging opening, and the oxidation furnace bottom is provided with leakage fluid dram.
The beneficial effects of the utility model are: this oxidation furnace thermal treatment zone is divided for two-stage, be upper and lower section heat exchanger, hot water is earlier through needing the higher hypomere heat exchanger of temperature, water after the heat exchange is injected into Re Baonei, adjust temperature at Re Baonei then and reach the epimere heat exchanger and be passed in the epimere heat exchanger after temperature required it is heated, make hot water obtain sufficient use like this and saved great amount of water resources.And the material input increases safe filter, can remove the impurity that has in the alcohol steam, so just reduces the side reaction in the oxidation furnace, guarantees the quality of subsequent handling product.
