Description
The technical field is as follows:
the utility model relates to a waste heat utilization technical field of power plant, concretely relates to latent heat of vaporization utilizes device above air cooling island of thermal power factory.
Background art:
at present, a primary fan and a blower of a thermal power plant are arranged in a boiler room, a shutter is arranged on the wall of the boiler room close to a filter screen at an inlet of the fan, the shutter is opened in summer to allow the fan to suck outdoor air, and the shutter is closed in winter to suck indoor air, so that the air temperature at the inlet of the fan is increased, but the ambient temperature in winter is low, and the temperature at the inlet of the fan cannot be ensured; and the latent heat of vaporization released above the air cooling island is not utilized, the temperature above the air cooling island in summer can reach 55 ℃, and the temperature above the air cooling island in winter can reach 30 ℃, so that a latent heat recovery system is urgently needed to be designed to apply the part of latent heat of the air cooling island to the inlet of the fan, and good effects of energy conservation and emission reduction are achieved.
The utility model has the following contents:
an object of the utility model is to provide a latent heat of vaporization utilizes device above air cooling island of thermal power factory.
The content of the utility model is as follows: the utility model provides a latent heat of vaporization utilizes device above air cooling island of thermal power factory, it includes the air cooling island the connection steelframe is installed on the top of air cooling island install trapezoidal collection cover on the connection steelframe, it is linked together with total wind channel to collect the cover install a plurality of branch wind channel along length direction equipartition on the total wind channel, the air outlet in branch wind channel is connected with fan entry wind channel install air conditioning baffle and filter screen in proper order on the branch wind channel, air conditioning baffle is connected with the driving motor transmission total wind channel with all install temperature measuring device on the branch wind channel.
Further, the air duct at the inlet of the fan is an air duct at the inlet of a primary fan or an air duct at the inlet of a blower.
The utility model has the advantages that: the utility model introduces the latent heat air above the air cooling island into the primary fan and the inlet of the air feeder, improves the air temperature of the inlet of the fan, reduces the heat loss of exhaust smoke, improves the heat efficiency of the boiler, improves the temperature of the primary hot air, is favorable for the drying output of the coal mill, effectively improves the outlet temperature of the coal mill, and leads the burner to catch fire quickly and stably; the utility model discloses getting off traditional shutter, having strengthened boiler house heat insulating ability, reduced personnel's operation, rational in infrastructure, the small investment, the benefit is big, easy to carry out, long service life has certain meaning to thermal power plant energy saving and consumption reduction, has fine popularization prospect.
