Abstract

The utility model discloses a sewage-draining waste heat recycling system for a biomass boiler. The sewage-draining waste heat recycling system comprises a sewage-draining flash tank, a water tank, a circulating pump and a plate type heat exchanger. By means of the sewage-draining flash tank and the plate type heat exchanger, waste heat of sewage is utilized to heat hot water required by the boiler. Thus, a lot of heat of sewage of the boiler can be recycled to be used by the boiler self, energy waste is avoided, the resource recycling principle is embodied, and energy is saved.

Description

Biomass boiler blowdown waste heat recycling system
Technical field
The utility model belongs to boiler afterheat recovery and utilization technology field, more specifically says the recycling system that belongs to boiler emission sewage remaining energy.
Background technology
In biomass boiler running, meeting continuous blowdown and periodical blowdown, the sewage that is directly given off afterwards a large amount of high steam and contained heat by flash vessel separation, owing to not being recovered utilization, has caused the waste of the huge energy.
Utility model content
The problem existing in order to solve prior art, the utility model provides a kind of system of effective recycling sewer waste heat.
In order to realize above object, the technical scheme that the utility model is taked is: a kind of biomass boiler blowdown waste heat recycling system, comprises blowdown system, water tank, circulating pump and plate type heat exchanger; The steam (vapor) outlet of blowdown system is connected with the steam inlet of water tank, the outlet of sewer of blowdown system is connected with the sewage inlet of plate type heat exchanger, the circulating water outlet of water tank connects pump entry, the recirculated water entrance of circulating-pump outlet connecting plate type heat exchanger, the circulating water outlet of plate type heat exchanger connects the recirculated water entrance of water tank.
Compared with prior art, biomass boiler blowdown waste heat recycling system is by blowdown system and plate type heat exchanger, by the required hot water of the waste-heat boiler of sewage, reclaimed a large amount of effluent from boiler heats, recycle to boiler self, stop energy waste, embody resource circulation utilization theory, save the energy.
Accompanying drawing explanation
Fig. 1 is living beings system for recycling residual heat of discharged sewage of boiler figure.
The specific embodiment
As shown in Figure 1, biomass boiler blowdown waste heat recycling system is comprised of blowdown system, water tank, circulating pump 2 and plate type heat exchanger 1.
The entrance of blowdown system is connected with the outlet of sewer of boiler, and the steam of blowdown system is introduced water tank, the sewage access plate type heat exchanger of blowdown system, and the recirculated water of water tank is introduced plate type heat exchanger 2 by circulating pump 2.
The operation principle of biomass boiler blowdown waste heat recycling system is as follows: the high temperature sewage of determining row's blowdown or platoon blowdown of boiler, enter blowdown system, because there is flash-off steam in the pressure decreased of blowdown system, this steam is introduced water tank, the water in heating water tank by the steam pipe at blowdown system top.Meanwhile, the hot sewage that blowdown system is discharged, enters plate type heat exchanger by blow-off line, and recirculated water heats up and enters water tank for heat recirculated water refluxes again in baffle heater with after sewer heat exchange.The recirculated water of baffle heater is introduced the recirculated water of water tank by circulating pump.Water tank hot water is finally supplied with boiler and is recycled, and after the heat exchange of blowdown hot water plate type heat exchanger, becomes low-temperature sewage and discharge.

Claims (1)
