Description
Technical field
The utility model relates to gypsum production unit, is specifically related to a kind of β semi-hydrated gypsum calcining kiln.
Background technology
Plaster of Paris makes plaster stone thermal dehydration by direct or indirect type of heating, the semi-hydrated gypsum of formation.Semi-hydrated gypsum is divided into αsemiwatergypsum and β semi-hydrated gypsum according to crystalline structure difference.Gypsum dewaters in high-temperature water solution or saturated steam, generation be exactly αsemiwatergypsum, in high temperature air dehydration generate be then β semi-hydrated gypsum.The process that gypsum sloughs crystal water in high temperature air is called gypsum calcination.
At present, the outer burning formula of employing and interior heated Tube gyp-incineration, kiln, divide downflow system and reverse-flow two kinds, namely refer to that material is identical with direction of heat flow or contrary.Downflow system is low temperature calcination gypsum, and reverse-flow be high-temperature calcined gypsum.It is no matter downflow system or reverse-flow, heat source high temp air flow inlet, heat source exhaust and material waste gas outlet all design at kiln body termination (downflow system) or kiln tail (reverse-flow), unreasonable structure, so that kiln hood or kiln tail piece is numerous, crowded, complicated, geometrical dimension is too huge, both affected attractive in appearance, given again installation, transport, maintenance band inconvenience; Heat source exhaust and material waste gas share an outlet, in the discharge process of waste gas, heat source exhaust containing impurity, ash content, carbon granule, with main component be moisture, the material waste gas of gypsum particle mixes, cause the bag-type dust regenerant of rear operation to be difficult to utilize, waste useful gypsum resource; Calcining kiln afterbody does not design filter sieve, affects quality product, even causes line clogging, or have in order to address this problem, install a filter sieve additional at afterbody temporarily, then add equipment cost.
Inventing type content
The purpose of this utility model is to provide the β semi-hydrated gypsum calcining kiln that a kind of each block construction is reasonable, heat source exhaust outlet separates with material waste gas outlet.
In order to achieve the above object, technical solution of the present utility model is: a kind of β semi-hydrated gypsum calcining kiln, comprises kiln body, reaction chamber, heating tube, material inlet, material waste gas outlet, material outlet, heat source high temp gas feed, heat source exhaust outlet.Be designed with material inlet, heat source exhaust outlet side by side in described kiln body front end, described material inlet communicates with reaction chamber, and described heat source exhaust outlet communicates with heating tube; Be designed with material waste gas outlet at kiln hood end face, described material waste gas outlet communicates with described reaction chamber; Be designed with heat source high temp gas feed at kiln hood position, this heat source high temp gas feed comprises heating tube with kiln body heat tunnel and communicates.
A kind of optimal technical scheme, described kiln body is designed to hollow interlayer, and described heat source high temp gas feed communicates with this kiln body interlayer.
A kind of optimal technical scheme, between described kiln body interlayer and heating tube, be designed with thrust-augmenting nozzle, described thrust-augmenting nozzle is positioned at described heating tube tail end, is communicated with by described kiln body interlayer with heating tube; Heat source high temp gas enters kiln body mezzanine space from heat source high temp gas feed and flows to kiln body caudal directions, by thrust-augmenting nozzle, then flows to heating tube by thrust-augmenting nozzle, flows to the heat source exhaust outlet in kiln hood direction from heating tube near kiln body tail position.
A kind of optimal technical scheme, in order to solve the blocking of calcining kiln afterbody, affects the problem of quality product, directly kiln body afterbody is designed to latticed or lattice-shaped, so both solving prior art Problems existing, again without the need to designing the filtration unit of afterbody in addition, reducing production cost.
Advantage of the present utility model: block construction connection and reasonable arrangement, saves cost of manufacture.Compared with the prior art, existing calcining kiln opening for feed, material waste gas outlet, heat source high temp hot air intake, heat source exhaust outlet all concentrate on kiln body termination, make kiln body termination too crowded and huge.And heat source exhaust exports and material waste gas outlet shares an exit passageway, so that the heat source exhaust containing impurity, ash content, carbon granule, with main component be moisture, the material waste gas of gypsum particle mixes, bag-type dust regenerant is difficult to utilize, and wastes useful gypsum resource.The utility model is by these block construction scattered distributions at kiln body termination and head, and above-mentioned material waste gas outlet, heat source exhaust export the separately design of two waste gas outlets, overcome these defects.Kiln body afterbody is designed to latticed, eliminates special filter sieve, has saved cost, solves the problem blocking and affect quality product simultaneously.
