Abstract

The invention discloses a biomass boiler blow-down waste heat recycling system which comprises a blow-down flash vessel, a water tank, a circulating pump and a plate type heat exchanger. Waste heat of sewage is used for heating hot water required by a boiler through the blow-down flash vessel and the plate type heat exchanger, a large amount of boiler sewage heat is recycled to be cyclically utilized by the boiler, energy waste is completely eradicated, the concept of resource recycling is represented, and energy is saved.

Description

Biomass boiler blowdown waste heat recycling system
Technical field
The invention belongs to boiler afterheat recovery and utilization technology field, more specifically say 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 directly gives off a large amount of high steam after being separated by flash vessel and contain heat, owing to not being recovered utilization, has caused the waste of the huge energy.
Summary of the invention
In order to solve the problem of prior art existence, the invention provides a kind of system of effective recycling sewer waste heat.
In order to realize above object, the technical scheme that the present invention takes 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 hot water required the waste-heat boiler of sewage, reclaim a large amount of effluent from boiler heats, recycle to boiler self, stop energy waste, embody resource circulation utilization theory, save the energy.
Brief description of the drawings
Fig. 1 is living beings system for recycling residual heat of discharged sewage of boiler figure.
Detailed description of the invention
As shown in Figure 1, biomass boiler blowdown waste heat recycling system is made up 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 refluxes and enter water tank for heat recirculated water 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.
