Abstract
The utility model relates to an improved mutual reserve double pneumatic motor, which is suitable for the cement rotary kiln intermediate bin coal dust preparation apparatus. A flared tube is additionally arranged between the air inlet pipe and the air outlet pipe of the double pneumatic motor; the air inlet pipe of the recirculating air pipe is moved to the air outlet pipe of the blower at the end of the kiln from the air outlet pipe of the exhaust fan in the kiln; a corresponding butterfly valve or a flange ram is arranged on the recirculating air pipe; the double pneumatic motor can be connected in series and reserve mutually.
Description
The utility model relates to the improvement of blower fan in the cement rotary kiln intermediate bin formula fuel pulverizing plant, particularly the improvement of two blower fans.
Two blower fans in the existing intermediate bin formula fuel pulverizing plant (coal mill exhaust blower and kiln hood gas blower) branch is arranged, coal mill exhaust blower must be synchronous with the coal mill, the kiln hood gas blower then must be synchronous with rotary kiln, not only power consumption is big, and will cause stopping production when in this two typhoons machine an appearance being arranged than major break down.
For addressing the above problem; according to " Cement industry thermal process and equipment " (Shandong Building Materials Industry Institute chief editor; China Construction Industry Press publishes; in July, 1985 the third printing) the 215th page of introduction; the pulverized coal preparation of intermediate bin formula also can be adopted single blower fan; it is the common typhoon machine that uses of coal mill air draft and kiln hood air blast; coal mill waste gas is all gone into kiln; this device flow process is simple, and power consumption is low, but its coal mill ventilation is decided by the primary air flow of kiln; coal mill ability can not be given full play to; and single blower fan is necessary and kiln; mill is synchronous, in case break down kiln; mill all will be shut down immediately.
The purpose of this utility model provides a kind of pair of blower fan and not only can connect and use but also can standby each other fuel pulverizing plant, when one of blower fan breaks down, still can guarantee the works better of coal mill and rotary kiln.
The purpose of this utility model is achieved in that the recirculating air arm of cancellation coal mill exhaust blower air outlet tube to bistrique, a straight pipe is set between kiln hood gas blower air outlet tube and blast pipe, at kiln hood gas blower air outlet tube and coal bistrique portion a recirculating air straight pipe is set, grinds exhaust blower into and out of a straight pipe also is set between the airduct at coal.Each straight pipe and blower fan are equipped with corresponding butterfly valve or flange flashboard on the airduct, kiln hood gas blower and coal mill exhaust blower are become not only can connect use but also two blower fans that can be standby each other.
The utility model is simple in structure, and is easy to use, and part waste gas all can return the mill circulation at any time, not only can guarantee the long-term safety operation of cement rotary kiln but also can save power consumption.
Now in conjunction with the accompanying drawings the utility model is further described:
Fig. 1 is the synoptic diagram of the fuel pulverizing plant with standby each other pair blower fan that proposes of the utility model.
Standby each other as seen from Figure 1 pair of blower fan intermediate bin formula fuel pulverizing plant is by run coal bin (A), coal mill (B), mill separator (C), cyclonic separator (D), Pulverized Coal Bin (E), coal mill exhaust blower (F), kiln hood gas blower (G), coal mill exhaust blower blast pipe (F1), air outlet tube (F2), kiln hood gas blower blast pipe (G1), air outlet tube (G2), straight pipe (I), straight pipe (II), straight pipe (III), butterfly valve (1), (5), (7), flange flashboard (2), (3), (4), (6) composition such as, recirculating air arm (IV) (dotted portion) has gone to disappear, when operation has only coal mill exhaust blower (F) work on kiln hood gas blower (G) stops, as long as open butterfly valve (1) and flange flashboard (3), (4), close butterfly valve (5) and flange flashboard (2), (6); When coal mill exhaust blower (F) is out of service when having only kiln hood gas blower (G) work,, close butterfly valve (1) and flange flashboard (3), (4) as long as open butterfly valve (5) and flange flashboard (2), (6); And when closing flange flashboard (2), (4), opened butterfly valve (1), (5) and flange flashboard (3), (6), the use of promptly connecting of two blower fans all can guarantee the rotary kiln safe operation.
