Energy-saving two-section type thermal treatment furnace for organic chemical industrial effluent

Abstract

The invention relates to an energy-saving two-section type thermal treatment furnace for an organic chemical industrial effluent, which comprises a furnace body and a furnace body bracket, wherein the furnace body has a vertical cylindrical structure; an igniting hole, a heating igniting device and a protective cover are arranged at the center of a steel plate of the furnace body bracket; the furnace body is composed of upper and lower two sections; a tapered separating plate is arranged between the two sections and the furnace body is divided into two combustors; an air outlet and a long-time burning device are arranged on the separating plate; a vertical concentration pipe is arranged in a first combustor; the upper part of the concentration pipe is bent and extends out of the furnace; a liquid inlet pipe is arranged outside the first combustor and is inserted into the concentration pipe; and an oxygen inlet pipe is arranged outside a second combustor and is inserted into the long-time burning device. The energy-saving two-section type thermal treatment furnace for the organic chemical industrial effluent has the advantages that: the thermal treatment furnace is simple in structure, convenient to operate and low in cost, and under the condition of loading auxiliary fuels, the burning of the organic effluent is burned, so that the organic effluent is concentrated and burnt and the generated steam is recycled, so as to achieve the energy-saving and environment-friendly purposes and realize the important economic value, environmental value and social value.

Description

technical field [0001] The invention relates to heat treatment equipment, in particular to a two-stage organic chemical waste liquid heat treatment furnace. Background technique [0002] For the treatment of organic chemical waste liquid, the usual methods include physical methods such as centrifugal separation, coarse-graining, and membrane separation; chemical methods such as acidification, chemical oxidation, and photocatalytic oxidation; physical and chemical methods such as flotation , adsorption method, magnetic adsorption separation method and biochemical methods such as activated sludge method and biofilm method. Although the above method has a good treatment effect, for most organic chemical waste liquids, the above method takes a long time, costs high, and the operation is relatively complicated, and at the same time requires a large treatment space. At present, although there are methods of treating organic chemical waste liquid by incineration at home and abroad...

Although the above method has a good treatment effect, for most organic chemical waste liquids, the above method is time-consuming, costly, and the operation is relatively complicated, and at the same time requires a large processing space

At present, although there are methods of treating organic chemical waste liquid by incineration at home and abroad, this process often causes the loss of heat and energy, and produces new pollutants and other disadvantages.
