Abstract
The utility model provides a kiln low temperature exhaust gas cycle recycle power generation system. Shortcoming to prior art, the utility model discloses to absorb be utilized by the low temperature exhaust gas of exhaust nearly 70%, participate in the thermal cycle in sending the cold machine of castor again back to, carry out the reutilization. The cold machine back of cement clinker entering castor, production high -temperature gas, some high -temperature gas get back to rotary kiln recycle, and some high -temperature gas entering rotary kiln afterbody carries on combustion -supportingly, and it is combustion -supporting that some high -temperature gas get into the boiler, and surplus high -temperature gas through draught fan entering chimney, forms the pressure -fired after getting into the heat collector before the entering chimney, be equipped with adjusting valve in the chimney lower half, adjust adjusting valve through the pressure size of manometer, and then wait before the control chimney to discharge low temperature exhaust gas's recovery proportion, the low temperature exhaust gas of recovery passes through the cold quick -witted recycle of cooling blower to re -enter the castor.
Description
Technical field
This utility model relates to rotary kiln clinker institute expellant gas residual-heat utilization technology, particularly relates to a kind of kiln low temperature waste gas cycling and reutilization electricity generation system。
Background technology
Cement in process of production, need to be calcined in rotary kiln, after clinker be discharged to grate-cooler carry out cooling down, carrying；There is provided hot-air for rotary kiln and dore furnace etc. simultaneously, be the capital equipment of cement production system recuperation of heat。But traditional recuperation of heat ratio is relatively low, it is only confined in and provides hot-air for rotary kiln and dore furnace etc., Some Enterprises unit also provides part heat empty institute for the heat supply of boiler, generating, but the cryogenic gas of 70% ratio will be discharged, cause the waste of waste heat data, environment is caused thermal pollution simultaneously, destroys natural environment。
Summary of the invention
In order to overcome deficiency of the prior art, this utility model provides a kind of kiln low temperature waste gas cycling and reutilization electricity generation system。For the shortcoming of prior art, the low temperature waste gas of be discharged nearly 70% is absorbed by this utility model, again sends back to participation thermal cycle in grate cooler, carries out secondary utilization。
For realizing object above, this utility model is by the following technical solutions: this utility model includes grate cooler, boiler, heat collector, air-introduced machine, cooling blower, it is characterised in that after clinker enters grate cooler, produces high-temperature gas, part high-temperature gas returns to rotary kiln and recycles, part high-temperature gas enters rotary kiln afterbody and carries out combustion-supporting, and part high-temperature gas enters boiler auxiliary combustion, after residue high-temperature gas enters heat collector, enter chimney by air-introduced machine, before entering chimney, form pressure-fired；In chimney lower half equipped with control valve, regulating control valve and then the recovery ratio of low temperature waste gas to be discharged before control chimney by manometric pressure size, the low temperature waste gas of recovery is again introduced into grate cooler by cooling blower and recycles。
In this utility model, equipped with Hot-blast valve and cold wind valve before cooling blower, regulate Hot-blast valve and cold wind valve size according to cooling blower leaving air temp, keep inlet temperature less than 75 DEG C。
Preferred as one, the control signal of control valve can be divided into two parts, local operation cabinet and computer centralized Control, regulate on the spot and computer collection control regulates realizing control valve。
Preferred as one, Hot-blast valve and cold wind valve can realize regulating on the spot and computer collection control adjustment。
Advantage of the present utility model: the secondary cycle achieving low temperature waste gas utilizes, it is achieved that energy-saving and emission-reduction, adds on-road efficiency。
