Abstract
A dynamic cooling system for a rotary kiln comprises a rotary kiln cylinder, a kiln head and a kiln tail. A refractory layer is arranged in the rotary kiln cylinder, a cooling water sleeve is arranged between the refractory layer and the rotary kiln cylinder at the position of the kiln head and comprises a main cavity, a water inlet pipe and a water outlet pipe, and the main cavity is arranged in the kiln head. A water outlet of the water inlet pipe penetrates into the main cavity through the refractory layer, a water inlet of the water inlet pipe is communicated with a water inlet main pipe, a water inlet end of the water outlet pipe is arranged in the main cavity, and a water outlet end of the water outlet pipe is communicated with a water outlet main pipe. One end of the water inlet main pipe is communicated with the water inlet pipe at a position of the center of one end of the rotary kiln cylinder, and the other end of the water inlet main pipe penetrates outside the kiln head to be connected with a rotary connector. One end of the water outlet main pipe is communicated with the water outlet pipe at a position of the center of the other end of the rotary kiln cylinder, and the other end of the water outlet main pipe penetrates outside the kiln head to be connected with the rotary connector. The dynamic cooling system for the rotary kiln has the advantages that by means of the cooling water sleeve additionally arranged at the kiln head, the refractory layer can be cooled, replacement times of the refractory layer can be reduced, cost is reduced, the rotary kiln cylinder is protected from corrosion, and the service life of the rotary kiln cylinder is prolonged. Further, since burrs coating the refractory layer are additionally arranged at a discharging port of the rotary kiln head, damage of the kiln head by ultrahigh-temperature materials is effectively prevented.
Description
Technical field
The invention belongs to metallurgical technology field, be specifically related to the dynamic cooling system of a kind of rotary kiln.
Background technology
In the production of metallurgy industry, chemical industry inorganic salts industry, cement building material industry, all can use rotary kiln.In smelting process; Because the temperature in the cylinder of rotary kiln is up to thousands of degree even higher; And production process need keep continuous state, so although the cylinder of rotary kiln inwall is provided with flame retardant coating, under the effects such as thermal etching that the high-temperature material in cylinder of rotary kiln continues and acid and alkali corrosion; Still can make flame retardant coating and cylinder of rotary kiln constantly encroached on and cause its damage, need correspondingly change after using certain hour.Simultaneously, cause the loss of a large amount of heat energy.Especially the discharging opening place of rotary kiln end is because of thermal etching and the acid and alkali corrosion that directly suffers high-temperature material, so damaged through regular meeting and influence production.Like this, carry out the replacing of flame retardant coating, not only will delay the duration, influence production efficiency, and increase huge production cost; And then say it, if the cylinder of rotary kiln sustain damage, that just will further strengthen production cost, reduce operating efficiency.And the great amount of heat energy loss causes energy waste.
Summary of the invention
The technical problem that the present invention will solve is: overcome the deficiency of prior art, provide a kind of rotary kiln dynamic cooling system, it can effectively reduce the temperature of cylinder of rotary kiln and flame retardant coating, prolongs its service life, thereby has reduced production cost, has improved productivity ratio; Improve the heat energy utilization rate.
The technical solution adopted for the present invention to solve the technical problems is: the dynamic cooling system of a kind of rotary kiln; Comprise cylinder of rotary kiln, kiln hood and kiln tail; Be provided with flame retardant coating in the said cylinder of rotary kiln, it is characterized in that: between the cylinder of rotary kiln at said kiln hood place and said flame retardant coating, a cooling jacket is set;
Said cooling jacket comprises main cavity, oral siphon, outlet pipe, and said main cavity is arranged at said kiln hood portion; The delivery port of said oral siphon passes to said main cavity through said flame retardant coating, and its water inlet and is gone into the supply mains and is communicated with; The water inlet end of said outlet pipe is arranged in the said main cavity, and its water side is communicated with an outfall sewer.
Preferably, a said end of going into the supply mains is in the place, centre of said cylinder of rotary kiln one end and said oral siphon UNICOM, and the other end is connected with a swivel joint; One end of said outfall sewer is in the place, centre and outlet pipe UNICOM of the cylinder of rotary kiln other end, and the other end is connected with a swivel joint.
Preferably, the said supply mains of going into is arranged at kiln tail or kiln hood; Correspondingly, said outfall sewer is arranged at kiln hood or kiln tail.
Preferably, set firmly prickle, on said prickle, cover flame retardant coating at said kiln hood top.
Preferably, said outlet pipe is more than one.
Preferably, said oral siphon is more than one.
Compared with prior art, the invention has the beneficial effects as follows:, both flame retardant coating was lowered the temperature owing between cylinder of rotary kiln and flame retardant coating, set up cooling jacket; Reduce it and change number of times; Reduce cost, made cylinder of rotary kiln avoid corroding again, prolonged its service life; The cooling jacket that use is made up of oral siphon, outlet pipe and main cavity can all be lowered the temperature whole cylinder of rotary kiln and interior flame retardant coating thereof; And as required, also can select to use the cooling jacket of forming by oral siphon, outlet pipe and cooling tubulation; The discharging opening place of rotary kiln end has set up prickle and has added and cover flame retardant coating, has effectively prevented the destruction of high-temperature material to kiln hood.Cooling jacket has absorbed a large amount of heat energy, has effectively improved the heat energy utilization rate.
