Embodiment Construction

[0022] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0023] Such as figure 1 As shown, the coking desulfurization sulfur foam and desulfurization waste liquid drying device of the present invention comprises coking desulfurization sulfur foam and desulfurization waste liquid conveying equipment screw pump 1, concentration equipment centrifugal atomizer 2, drying equipment drying tower 3 and tail gas The treatment equipment is a cyclone separator 8, and the tail gas treatment equipment adopts two cyclone separators 8 connected in series. Among them, a settling device settling tank 13 is arranged between the drying tower 3 of the drying equipment and the cyclone separator 8 of the tail gas equipment to settle the particles in the dry tail gas discharged from the drying tower 3 of the drying equipment, so as to prevent the particles in the dry tail gas from entering the tail gas treatment In the cyclone s...

Abstract

The invention discloses a drying device for coking desulfurized sulfur foam and desulfurized effluent. The device comprises a desulfurized sulfur foam and desulfurized effluent conveying device, a drying device and a tail gas treatment device which are connected with each other in turn, wherein a settling device is arranged between the drying device and the tail gas treatment device, and an outlet of the tail gas treatment device is connected with a gas inlet of a tail gas cleaning device. The device disclosed by the invention can effectively treat the desulfurized sulfur foam and desulfurized effluent; two sulfur-bearing wastes are dried together, so that salt-containing crude sulfur powder is acquired; and the device has a simple structure, is low in cost, is easy in operation and can successfully solve the problems of environmental pollution and high running cost of the prior art.

Description

technical field [0001] The invention discloses a drying device, in particular to a drying device for coking desulfurization sulfur foam and desulfurization waste liquid. Background technique [0002] Coking gas desulfurization by-product sulfur foam drying belongs to the category of sulfur production, but the sulfur foam contains more impurities and generally needs to be purified. At present, there are several types of sulfur purification methods: ①melting method, which has problems such as low purity of recovered sulfur, low sulfur yield, high energy consumption, and high production cost; ②extraction method, using an extractant to dissolve sulfur in the material And adopt the method of solid-liquid separation to separate sulfur. Commonly used extractants include carbon disulfide, tetrachlorethylene, carbon tetrachloride, etc.; ③ sublimation method, that is, the principle of heating sulfur to the boiling point and then evaporating for purification. The above methods are ma...
