The energy-saving quick drying kiln has the advantages that the energy-saving quick drying kiln is lower in energy consumption, high in drying rate, and relatively environment-friendly.
Description
Technical field
The present invention relates to the kiln technical field, especially relate to a kind of energy-conservation quick drying kiln.
Background technology
The brick embryo dry kiln of Building Ceramics Industry is broadly divided into common dry kiln and quick drying kiln.Each tool pluses and minuses both, make a concrete analysis of as follows:
One, common dry kiln.Its advantage is: can utilize the flue gas of kiln and waste heat as thermal source, thereby self burnup is zero.Its shortcoming is: arid cycle is longer, and the control of adjustment, humidity regulation, convection current is relatively poor.
Two, quick drying kiln.Its advantage is: arid cycle is short.Its shortcoming is: each independently the circulatory system independently circulating fan and combustor need be equipped with, burnup and power consumption are all very large.
Pluses and minuses for above-mentioned two kinds of dry kilns compare, and what we are not difficult to be found to be and both up to the present also have very large living space.That is: Production of Ceramics producer selects the main cause of common dry kiln to be to need not to consider burnup, and production cost is lower; Select the main cause of quick drying kiln to be to access shorter production cycle and less space hold.Therefore, people extremely expect to occur can comprehensive two kinds of dry kiln advantages kiln.
Summary of the invention
The purpose of this invention is to provide a kind of energy-conservation quick drying kiln, it is lower that it has energy consumption, and rate of drying soon, the characteristics of environmental protection comparatively.
The technical solution adopted in the present invention is: energy-conservation quick drying kiln, comprise the kiln body, be communicated with warm-air pipe and dehumidifier pipe on this kiln body, and the dehumidifier pipe is connected with air exhauster, described warm-air pipe is connected with waste heat apparatus or the flue gas displacement apparatus of kiln, simultaneously, be communicated with steam pipe on the kiln body, this steam pipe is connected with steam raising plant.
Described kiln body is provided with humidity measurement instrument.
Described kiln body is provided with temperature monitor.
The advantage that compared to the prior art the present invention has is: energy consumption lower (drying of the present invention self burnup is 0), and rate of drying soon, comparatively environmental protection.Make a concrete analysis of as follows:
The three large key elements that affect rate of drying are temperature, humidity and convection current.Analyze as can be known from the drying principles of common dry kiln and quick drying kiln: with regard to common dry kiln, its internal temperature is controlled.That is, the flue gas and the waste heat supply temperature that draw from kiln are all higher, and flue gas and the waste heat supply temperature of even in most cases large-tonnage kiln discharging are all high, and utilizing even needs to join cold wind and reduce temperature in process.But, contain certain moisture content inside flue gas, and waste heat is the hot-air of doing substantially.The water evaporates speed on some dry adobes surface surpasses the words of the moisture content that the adobe internal moisture moves to the surface, the brick embryo just is easy to cause because rate of drying is too fast cracking so, so the user is used for the thermal current of dry brick and all contains certain humidity, in order to solve preferably the problem of Cracking that adobe causes because draining is too fast.Common dry kiln comes dry brick with flue gas, the humidity of flue gas own does not reach our needed humidity, so it is many that common dry kiln is debugged the flue gas that is delivered into often in the kiln body, the flue gas of releasing is few, and the moisture content that purpose is to make the evaporation adobe to produce can be stayed kiln body inside and guarantee needed humidity.Yet two dry elements have been satisfied so at the most: temperature and humidity.But the heat-supplying mode of common drying is the drum hot blast to be advanced in kiln, heating is conducted in adobe, heating is inhomogeneous like this, adobe is surface-dry fast, and the adobe internal temperature is low, and water evaporates slow ftractures because the speed of inside and outside moisture drying is inconsistent in case add the words adobe meeting of strong convection, so such mode of heating has just limited its convection current can not be strong, the last one will make the adobe cracking; And quick drying kiln has just well solved this point: utilize tubule to bore aperture, facing to the hot blast that directly blows with certain humidity at the bottom of brick face and brick, adobe is heated, heating is more even like this, and there is the circulating fan of a platform independent each unit, after being delivered into the Hot-blast Heating adobe in the kiln body, moisture content has been evaporated in adobe, and these moisture content are released by circulating fan.At this moment, if humidity has surpassed our needed humidity, discharge a part by total dehumidifier blower fan, the hot blast of these remaining low temperature and high humidity is heated to our needed temperature by combustor again, so, temperature, humidity, convection current can both be controlled in single circulation, reaches quick-drying purpose.
By above analysis as can be known, humidity problem be can solve preferably if the kiln body of kiln is interior in the situation that temperature is enough, the common dry kiln of comprehensive prior art and the advantage of quick drying kiln got final product.And energy-conservation quick drying kiln of the present invention utilizes the waste heat of kiln or flue gas to replace the rear clean hot-air that obtains as thermal source, makes to have enough temperature in the kiln body; The kiln body is communicated with steam pipe, makes to have enough humidity in the kiln body.Simultaneously, the dehumidifier pipe can in time be adjusted the convection current in the kiln body.Like this, reached the purpose of kiln body rapid draing adobe from temperature, humidity and convection current three aspects:.After optimization, the humidity measurement instrument that is equipped with on the kiln body and temperature monitor.Like this, after the user regulates the temperature and humidity in the kiln body, directly be conveyed into humidity-controlled hot-air with heat exchange is carried out in adobe in the kiln body, exchanged and all extracted out outside kiln more afterwards.(in the situation that humidity relative saturation, make the adobe intensification of absorbing heat rapidly, when adobe inside and outside temperature reaches unanimity and is higher, progressively reduce again the water vapour content of squeezing into hot-air, namely reduce the humidity of drying medium, it is adobe draining smooth and easy quickening gradually, because the adobe internal-external temperature difference is little, adobe is not easy cracking at this moment) simultaneously, because energy-conservation quick drying kiln of the present invention utilizes hot-air after the waste heat of kiln or flue gas displacement heat as thermal source, can be to equipment and environment, and need not consume fuel again, thus very energy-conservation.
