The cold slag machine of water cold drum formula is the cooling that is widely used in nearly 1000 celsius temperature slags that power plant CFBB, garbage burning boiler discharge and carry the energy-conserving and environment-protective equipment that carries out the high temperature furnace slag waste heat recovery, and the dried slag of discharge can also fully utilize.Improve boiler thermal output for power plant, save operating cost, remarkable economic efficiency is arranged.
The structure of the spiral cold slag tube of existing cylinder type cold slag machine is made up of cold slag tube and flight as shown in Figure 1.When cold slag machine moves, driving cylinder by drive unit slowly runs, the high temperature furnace slag that enters slag feeding chamber from slag inlet flows into respectively the many spiral cold slag tubes that are provided with in the cylinder, high temperature furnace slag in cold slag tube along in the helicla flute rolling course of conveying, cooling water directly enters in the cylinder by the swivel joint water inlet, slag is walked in pipe, cooling water is in the pipe outflow, carry out countercurrent heat exchange, thereby the slag about 1000 degrees centigrade is cooled to below 100 degrees centigrade, cooling water after the heat exchange is discharged through the delivery port of swivel joint, and the boiler of feeding feedwater is used.
The problem of cylinder type cold slag machine existence at present has: cylinder type cold slag machine is owing to be subjected to the restriction of cylinder inner space, the limited amount of cold slag tube is set, cold slag machine is only by cold slag tube surface (single face) cooled slag, the confidential increase film-cooled heat of cold slag just must strengthen diameter of cylinder with quantity that increases cold slag tube or the length that increases cold slag tube.So, make that the volume of cold slag machine is big, consumable quantity is big, the manufacturing cost height.
The utility model content
The utility model technical issues that need to address just are to overcome the defective of prior art, provide a kind of two-sided water cold drum formula cold slag machine, it is provided with the cooling water circulation line in the spiral cold slag tube, make spiral tubular axis and flight all become cooling surface, slag is cooled off in cold slag tube inside and outer surface (two-sided).It can increase the film-cooled heat of cold slag machine, can dwindle the volume of cold slag machine again, have bigger than the film-cooled heat of cold slag machine of the same type, good cooling results, advantage such as the cooling water consumption is few.
For addressing the above problem, the utility model adopts following technical scheme:
The cold slag machine of a kind of two-sided water cold drum formula of the utility model, comprise cylinder, spiral cold slag tube and cooling water circulation line, spiral cold slag tube and cooling water circulation line are installed in the cylinder, be provided with a spiral tubular axis in the described spiral cold slag tube, be with a return pipe in the spiral tubular axis, shut with stifle and end socket cover plate respectively at described spiral tubular axis two ends, and spiral tubular axis one end side surface has an inlet opening; Be welded with flight on the described spiral tubular axis, described flight welding by both sides is connected on the spiral tubular axis, and whole helix tube inserts in the cold slag tube, cold slag tube two ends inwall and flight welding, and whole helix tube is fixed in the cold slag tube.
Cylinder one end described in the utility model is a slag feeding chamber, and the other end is the cooling water water inlet end, is provided with many spiral cold slag tubes in the cylinder, and described spiral cold slag tube and slag feeding chamber are connected; Be provided with the center water inlet pipe in the centre of the drum, described center water inlet pipe connects water inlet by swivel joint, the center return pipe is installed in the water inlet pipe of center, be provided with the distribution water tank near water inlet position on the water inlet pipe of described center, described distribution water tank is communicated with every spiral cold slag tube water inlet pipe respectively, described spiral cold slag tube water inlet pipe and spiral tubular axis inlet opening are communicated with, return pipe in the spiral tubular axis is communicated with annular collecting box pipe respectively, described annular header pipe and cylinder water inlet pipe are connected, described center return pipe and cylinder are connected, and the center return pipe is communicated with the swivel joint delivery port.
Principle of the present utility model is: when slag was carried in the spiral cold slag tube, cooling water was introduced into the distribution water tank by the swivel joint water inlet, was redistributed in the interlayer of the return pipe that is provided with in every cold slag tube spiral tubular axis and the spiral tubular axis.The cooling surface of forming by spiral tubular axis and flight, in cold slag tube inside high temperature furnace slag is carried out countercurrent heat exchange: the cooling water after the heat exchange flows out from the return pipe of helix tube, enter the annular header manifold General Logistics Department, again in one or several cylinder water inlet pipe flow into cylinder.Cooling water in the cylindrical shell again with cold slag tube in slag outside pipe, carry out countercurrent heat exchange, the slag about 1000 degrees centigrade is cooled to below 100 degrees centigrade.Cooling water in the cylindrical shell after the heat exchange is discharged from the swivel joint delivery port through the center return pipe, and the boiler of feeding feedwater is used.
The utility model is provided with the cooling water circulation line in the spiral cold slag tube after, slag is cooled off with the surface is two-sided in cold slag tube inside, can increase the film-cooled heat of cold slag machine like this, can dwindle the volume of cold slag machine again, reach the film-cooled heat that both increases cold slag machine, dwindled the long-pending purpose of cold slag body again.Actual cooling effective area is than single face cooling having increased 30%--40%.The length of cold slag machine can shorten 20%--30%, has reduced the volume and the steel consumption of cold slag machine.And improved cold slag effect, deslagging temperature can reduce about 25 ℃.
