Abstract
The utility model relates to a desulfurizing and regenerating apparatus. The utility model is characterized in that: the upper position of a desulfurizing tower is provided with a regeneration tower, one side position of the upper part of the desulfurizing tower is provided with a self priming type regenerative device, and the upper part of the regeneration tower is connected with the bottom of a tail gas recovery device whose upper part is connected with a tail gas outlet. The utility model has the advantages that the ejection self priming type regeneration is adopted, air is not needed to be compressed, the desurfurizing and the regeneration are made to integration, the floor space is furthest saved, the doctor solution after being regenerated automatically flows from the upper part to the desurfurizing section of the lower part, and thus a delivery system from the regeneration to the desulfurizing is saved. A light supporting structure provided with supporting fillers and a redistributed function is adopted by the desurfurizing section to avoid the bias current phenomenon of gas and liquid and implement the macro-scale operations technology of filler desurfurizing equipment. Three modes of regeneration operations are implemented by adopting the regenerator section of a novel self priming type double-structure. The production plant can select according to the practical situation.
Description
Technical field:
The utility model relates to the technical field of industrially desulfurized reclaim equiment, specifically a kind of desulphurizing and regenerating device.
Background technology:
The main equipment of existing desulfurization regeneration equipment is: thionizer and regenerator column, they each two equipment independently naturally, middle supporting have liquid seal trough, reaction liquid bath, doctor solution recycle pump, regulator of level, air compressor etc., its desulfurization regeneration technology is: doctor solution, pressurized air enter from the regenerator column bottom, from the top doctor solution after regenerating is sent back to thionizer by regeneration, the sulphur foam removes sulfur melting kettle, and tail gas (contains a large amount of NH
3, H
2Waste gas such as S, HCN) directly be discharged into the atmosphere from the cat head venting hole, the shortcoming of this kind equipment is: floor space is big, and the equipment initial stage drops into and routine maintenance cost height, and the environmental issue of exhaust emissions can't solve.
Summary of the invention:
The purpose of this utility model is to provide a kind of desulphurizing and regenerating device, and it can overcome some shortcomings of the prior art.
To achieve these goals, the technical solution of the utility model is: a kind of desulphurizing and regenerating device, it mainly comprises desulfurizer and regenerating unit, it is characterized in that: place, thionizer top is provided with regenerator column, one side place, thionizer top is provided with self-priming regenerating unit, regenerator column top is connected with the bottom of device for recovering tail gas, and device for recovering tail gas top is connected with exhaust port.
The utility model provides the desulfurization regeneration tower, its advantage is: first, adopt the self-priming regeneration of injection, do not need pressurized air (a large amount of 0.4～0.5Mpa pressurized air of present reclaiming process needs), second, desulfurization regeneration unites two into one, saved occupation of land to greatest extent, doctor solution after the regeneration flows automatically to the bottom desulfurization section from top, saved from regenerating to the delivery system (pump type systematic) of desulfurization, the 3rd, desulfurization section adopts the novel support filler that has, the light-duty supporting structure of distributed function again, avoided gas-liquid bias current phenomenon, realized the maximization of filler sweetener, the 4th, the RS Regenerator Section of employing self-priming formula dual structure has realized the regenerative operation of three kinds of patterns (can arbitrarily switch), and factory can select according to practical situation.Three kinds of operation element states are respectively: first kind of operational stage is the method for using at present, adopts new air regenesis fully, and the waste gas after the regeneration (contains NH
3, H
2S, HCN) all dischargings; Second kind of operational stage is to suck a certain amount of new air regenesis, a part of exhaust gas emission, and it is about about 1/3 that exhausted air quantity can reduce, and therefore reduced emission of harmful substances, and partially recycled NH in the coal gas
3, H
2S, HCN; The third operational stage is the air regenesis that sucks certain quantity of fresh, before another part waste gas is got back to gas blower, accomplishes non-exhaust emission, thereby has avoided emission of harmful substances, and reasonably reclaimed the NH in the coal gas
3, H
2S gets back to that waste gas makes the oxygen level of coal gas increase to 0.08～0.1% in the coal gas, can not influence the use of coal gas.
