Abstract
The utility model discloses a hydrogen fluoride (HF) converter slag returning and reacting device which comprises a converter, a spiral device and an inner slag returning system. The spiral device and the inner slag returning system are located in the converter, the spiral device is connected to the position of a converter head of the converter, and the inner slag returning system is a mechanical device formed by spirally combining multiple sections of inner slag returning barrel bodies. A discharging hole is arranged at the top end of the inner slag returning system and horizontally faces the converter head of the converter, the tail end of the inner slag returning system is provided with a feeding hole, and a grabbing bucket is arranged at the position of the feeding hole. By means of the HF converter slag returning and reacting device, the HF yield can be effectively improved, and energy consumption is reduced. In addition, heat brought by a large amount of hot calcium sulfate returns to the feeding end from the rear end of the converter in the production process and rapidly heats reaction materials fed into the converter, so that energy is further saved.
Description
Technical field
The utility model relates to a kind of converter slag and returns reaction unit again, and particularly a kind of HF converter slag returns reaction unit again.
Background technology
General in the world spiral circulation device; Be to rotate together by its device integral body and stove inwall; Do not need other transmission mechanism; Be installed on the fixed position of stove inwall, conventional spiral circulation device comprises with two helical channels in the concentric round shape transfer lime of stove, two extraction elements (containing two slide plates and a plurality of clavate sub-sieve), annular plate washer and a plurality of support.When by-product calcium sulfate gets into two helical channels of spiral circulation device, will return the ingress, reactant carries out the round-robin by product simultaneously to be mixed.Establish sub-sieve in the extraction element, prevented that the bulk by product from getting into the e Foerderanlage helical element, two extraction elements are installed between transfer lime and the stove inwall; Becoming angle mutually is 180 °; Two slide plates have certain inclination angle, can make the smooth and easy entering circulation device of material, and ring baffle can make extraction element accept required by product; And make its circulation, also can accumulate sufficient by product.The advantage of this method is that when rotary kiln inner casing and certain on-stream specified time of circulation device an extraction element extracts by product from the inner casing bottom of stove, and other extraction element can be sent into by product the downside of transfer lime at this moment.Two extraction elements will replace to be sent into quantitative by product in the helix transporting device.But the shortcoming of this structure is; When by product piece pair is big, be difficult for getting into the e Foerderanlage helical element, also can influence the conveying function of e Foerderanlage, and this kind device adopted ring baffle; This structure makes material produce the bonding phenomenon easily, can produce stronger corrodibility to body of heater.
The utility model summary of the invention
Goal of the invention: in order to overcome the deficiency of prior art, the utility model provides a kind of raising HF production capacity, and the converter slag that cuts down the consumption of energy returns reaction unit again.
Technical scheme: the described a kind of HF converter slag of the utility model returns reaction unit again, comprises converter, spiral organ and internal return slag system, and spiral organ and internal return slag system are positioned at converter; And spiral organ is connected in converter burner place; Said internal return slag system is the mechanism of return slag cylindrical shell spiral combination in two sections, and its top is provided with discharge hole, and level is facing to the converter burner; Tail end is provided with feed port, and the feed port place is provided with and copies bucket.
Principle of work: the innovative point of the utility model is in converter, to be provided with spiral organ and internal return slag system, and said internal return slag system is the mechanism of return slag cylindrical shell spiral combination in the multistage, is provided with discharge hole at its top end; Tail end is provided with feed port; And the feed port place is provided with copies bucket, and said spiral organ is the squirrel-cage spiral organ, and is linked in converter burner place; Material carries out propelling and the stirring of normal reaction through spiral organ after converter feeds intake; Material is mentioned to interior return slag cylindrical shell by copying bucket through feed port when reacting back segment, rotates through converter to drive internal return slag cylindrical shell and rotate, and will expect that slag is transferred to the discharge hole place; Carry out again stirring with the mixing of reaction raw materials and with slag in not the complete reaction by product fully react increase output.
Beneficial effect: the described a kind of HF converter slag of the utility model returns reaction unit again, can make in the converter material with in material slag in the anti-slag system fully react again, thereby improve the output of HF, reduce unit consumption.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
As shown in Figure 1, a kind of HF converter slag of the utility model returns reaction unit again, and this device has converter 1, spiral organ 2 and internal return slag system 3; Spiral organ 2 is positioned at converter 1 with internal return slag system 3, and spiral organ 2 is linked in converter 1 burner place, and said internal return slag system 3 be the mechanism that return slag cylindrical shell spiral makes up in the multistage; Its top is provided with discharge hole 4; And level is facing to the burner of converter 1, and tail end is provided with feed port 5, and is provided with at feed port 5 places and copies bucket 6.
When carrying out the HF production operation; Carry out normal reaction after in converter 1, dropping into material; Through the propelling and the stirring of spiral organ, material is mentioned to internal return slag system 3 by copying bucket 6 through feed port 5 when reacting back segment, drives internal return slag system 3 through converter 1 and rotates; To expect that slag is transferred to burner discharge hole 4 places, carry out again stirring with the mixing of reaction raw materials and and slag in Calcium Fluoride (Fluorspan), the sulfuric acid of complete reaction fully do not react.Wherein CaF2, CaSO4, H2SO4 form suitable solid-to-liquid ratio; The reaction mass that disperses the thickness state effectively; Reduce on the one hand the sticking wall of thickness state material and to the corrosion of body of heater; Again unreacted CaF2 and H2SO4 in the residue are reacted once more on the other hand, increase output, reduce unit consumption.And get back to feed end because big calorimetric calcium sulfate carries heat from the converter rear end, heating gets into the reaction mass of converter rapidly, and is more energy-conservation.
Claims (2)
