Abstract
The utility model relates to a residual-heat utilization device for a mechanical cement shaft kiln, which belongs to the class of heat exchangers. The residual-heat utilization device is designed in order to solve the problem that emitted residual heat can be made use of in the process of raw material calcination of the mechanical cement shaft kiln. A water tank 1 of a discharge pipe, a water tank 2 of a left chimney, a water tank 3 of a right chimney is arranged on the outer walls of chimneys of the mechanical cement shaft kiln and the discharge pipe. Water inlets and water outlets are arranged on the outer shells of the water tanks. The residual-heat utilization device for a mechanical cement shaft kiln is formed by that the chimneys, the water tanks, the water inlets and the water outlets are connected through a pipeline. The utility model is suitable for mechanical cement shaft kiln producing enterprises. The utility model has the advantage that the residual-heat utilization device can better make use of the residual heat of the mechanical cement shaft kiln and cool clinker which is discharged from the cement shaft kiln.
Description
The utility model relates to a kind of heat exchanger.
Up to the present, medium-sized and small enterprises generally adopt mechanical vertical kiln to produce cement, in the cement sintering process, mechanical vertical kiln has wasted much at the heat that calcining contains the generation of coal raw material, wherein a part is taken away from chimney, and also some is taken away from discharge port by grog, can not obtain utilizing.
The device that provides a kind of waste heat that mechanical cement in vertical kiln is produced when calcining contains the coal raw material to obtain utilizing is provided the purpose of this utility model.
For achieving the above object, the technical solution adopted in the utility model is: the outer wall system water tank at the main heat radiation position of mechanical cement in vertical kiln, system water inlet and delivery port connect to form this device by pipeline on the shell of water tank.
The utility model is described in further detail with embodiment with reference to the accompanying drawings below:
Fig. 1 is the structural representation of the utility model machinery cement in vertical kiln residual heat using device.
Also the outer wall of discharge duct is also made the part of discharge duct tank shell with iron sheet weldering system discharge duct water tank 1 around the discharge duct outer wall of mechanical cement in vertical kiln, discharge duct water tank 1 outer casing underpart leaves water inlet, and on water inlet, be installed into penstock, delivery port is left on the top of discharge duct water tank 1, and flowing water Valve is installed on the delivery port; Each chimney outer wall around mechanical cement in vertical kiln, with iron sheet weldering left chimney water tank 2 of system and right chimney water tank 3, and the chimney outer wall is made the part of left chimney water tank 2 and right chimney water tank 3, water inlet is left in each chimney tank shell bottom, and on water inlet, be installed into penstock, delivery port is left on top at each chimney tank shell, and flowing water Valve is installed on the delivery port, and the inlet valve of the flowing water Valve of left chimney water tank 2 with right chimney water tank 3 is connected with pipeline; With pipeline the inlet valve of the flowing water Valve of discharge duct water tank 1 and left chimney water tank 2 is linked together and promptly to make this device.
During use, the inlet valve of discharge duct water tank 1 be connected to press cold water pipe after, opening all inlet valves and flowing water Valve gets final product, cold water enters this device back carry out heat exchange with discharging tube wall, chimney wall after, flow out right chimney water tank 3, flow out the hot water of right chimney water tank 3, can be used for pan-pelletizer balling-up water, make raw material obtain preliminary preheating before advancing shaft kiln, the worker who also can be used for cement production enterprise has a bath and heat supply in winter.Behind the cold water process discharge duct water tank 1, can reduce the kiln discharge clinker temperature preferably simultaneously, improve clinker quality, reduction discharge duct and grog send defeated, and the wearing and tearing of process equipment prolong its service life.
This device reaches the condition of production according to actual needs also can separate independent use, and as only with the discharge duct waste heat time, the water inlet of discharge duct water tank 1 is connected to the pressure cold water pipe, and delivery port connects uses hot-water line; As only with the chimney waste heat time, the water inlet of left chimney water tank 2 is connected to the pressure cold water pipe, and the delivery port of right chimney water tank 3 connects uses hot-water line.
After the machinery cement in vertical kiln uses this device, has following beneficial effect: 1, this device and mechanical cement Shaft kiln discharging pipe, chimney directly contact, and waste heat can obtain utilizing, the hot water of generation can be used for having a bath or Enterprise's heat supply in winter and raw material balling-up water make into the kiln raw material and obtain preliminary preheating, reduce heat consumption of clinker; 2, this device can reduce the clinker discharging temperature preferably when discharge duct is installed water tank, improves ripe The material quality, reduction discharge duct and grog send defeated, and the wearing and tearing of process equipment prolong its service life.
Claims (3)
1, a kind of mechanical cement in vertical kiln residual heat using device is characterized in that the main heat radiation position outer wall dress system water tank around mechanical cement in vertical kiln, and each tank shell is shaped on water inlet and delivery port, is connected by pipeline.
2, mechanical cement in vertical kiln residual heat using device according to claim 1 is characterized in that described main heat radiation position outer wall is the part of tank shell, and the tank shell Lower Half is shaped on water inlet, and the first half is shaped on delivery port.
