Abstract
The utility model discloses the heat accumulating type feed system of a kind of biomass steam and waste heat thereof, comprise biomass steam boiler, storage heater, water tank, control valve, this system is set up storage heater and blowdown system in original steam supply system, on the one hand, in the time that the steam demand amount with steaming plant increases suddenly, storage heater discharges the steam of storage, avoid biomass steam boiler overload operation, produce steam product up to standard to ensure biomass steam boiler, on the other hand, by blowdown system, the waste heat recovery of sewage is resupplied to storage heater, reclaim a large amount of effluent from boiler heats, stop energy waste, effectively save the energy.
Description
Technical field
The utility model belongs to living beings heat supply process field, specifically relates to the heat accumulating type feed system of a kind of biomass steam and waste heat thereof.
Background technology
In biomass steam boiler heat supplying process, if the steam use amount fluctuating range of subscriber equipment is large, when vibration frequency is also high, bring unfavorable factor can to the even running of boiler.The hoisting velocity that biomass steam boiler is produced quantity of steam is at short notice slower than traditional fuel-oil or fuel-gas boiler, be that biomass steam boiler cannot rise to rapidly large output from little output at short notice, but in the time that user rises to large consumption from little consumption fast, because biomass steam boiler is produced quantity of steam and is not caught up with the demand of subscriber equipment far away, can make biomass steam boiler steam pressure moment decline, the steam quality of producing cannot reach user's requirement.Meanwhile, biomass steam boiler is produced in the process of steam, meeting continuous blowdown and periodical blowdown, and 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.
Utility model content
The problem existing in order to solve prior art, the utility model provides a kind of being suitable for to fluctuate widely or instantaneous consumption quantity of steam is large and biomass steam that can effective recycling sewer waste heat and the heat accumulating type feed system of waste heat thereof with quantity of steam.
In order to realize above object, the technical scheme that the utility model is taked is: the heat accumulating type feed system of a kind of biomass steam and waste heat thereof, comprise biomass steam boiler, also comprise storage heater, blowdown waste heat flash vessel, water tank, control valve, between described biomass steam boiler and storage heater, be connected steam pipe, between biomass steam boiler and water tank, be connected feed pipe, between storage heater and water tank, be connected condensate pipe, storage heater steam (vapor) outlet is installed control valve, between biomass steam boiler and blowdown waste heat flash vessel, be connected blow-off pipe, between blowdown waste heat flash vessel and water tank, be connected hot-water line.
Compared with prior art, the utility model, owing to setting up storage heater and blowdown system in original steam supply system, has two aspect advantages:
On the one hand, in the time that the steam demand amount with steaming plant increases suddenly, storage heater discharges the steam of storage, to meet the steam demand with steaming plant, during storage heater discharges steam, biomass steam boiler has grace time to promote producing steam amount, avoids biomass steam boiler overload operation, to ensure that biomass steam boiler produces steam product up to standard;
On the other hand, by blowdown system, the waste heat recovery of sewage is resupplied to storage heater, reclaimed a large amount of effluent from boiler heats, stop energy waste, effectively save the energy.
Brief description of the drawings
Fig. 1 is the structural representation of the heat accumulating type feed system of biomass steam and waste heat thereof.
Detailed description of the invention
As shown in Figure 1, the heat accumulating type feed system of biomass steam and waste heat thereof is made up of biomass steam boiler, storage heater, blowdown waste heat flash vessel, water tank and pressure-reducing valve 1, and this system provides steam to heat exchanger.
Between biomass steam boiler and storage heater, be connected steam pipe, between storage heater and heat exchanger, be connected steam pipe, between biomass steam boiler and water tank, be connected feed pipe, between storage heater and water tank, be connected condensate pipe.Steam outlet at storage heater is installed pressure-reducing valve 1, for the pressure of regulation output water vapour.Between biomass steam boiler and blowdown waste heat flash vessel, be connected blow-off pipe, between blowdown waste heat flash vessel and water tank, be connected hot-water line.
The operation principle of the heat accumulating type feed system of biomass steam and waste heat thereof is: biomass steam boiler is produced steam incessantly, and the steam of generation is exported to heat exchanger again through storage heater.When more steady with quantity of steam, storage heater is only used as heat accumulation equipment.When heat exchanger with quantity of steam hour, turn down storage heater output quantity of steam by pressure-reducing valve 1, reduce steam supply, reach the steam equilibrium of supply and demand, surplus steam is stored in storage heater.The water of storage heater inside absorbs vapour latent heat, and water vapour is condensed into water, and the water level of storage heater inside raises.In the time that water level is higher, condensate pipe drains into water tank storage all.In the time that heat exchanger increases suddenly with quantity of steam, heighten storage heater output quantity of steam by pressure-reducing valve 1, and along with the decline of storage heater internal vapor pressure, a part of water flash distillation of storage heater inside is converted to steam, to give heat exchanger sustaining supply steam delivery volume, the water level of storage heater inside reduces gradually.Increase in the process of steam delivery volume at storage heater, biomass steam boiler has the sufficient time to improve production capacity for steam, meets continuous Production requirement, and now, if boiler water deficiency, water tank can be to boiler water-filling.Biomass steam boiler is produced in the process of steam, the high temperature sewage of determining row's blowdown or platoon blowdown of boiler, enter blowdown system by blow-off pipe, because flash-off steam can occur the pressure decreased of blowdown system, this steam is introduced in storage heater and is stored or recycle by hot-water line.
Claims (1)
1. the heat accumulating type feed system of a biomass steam and waste heat thereof, comprise biomass steam boiler, it is characterized in that: also comprise storage heater, blowdown waste heat flash vessel, water tank, control valve, between described biomass steam boiler and storage heater, be connected steam pipe, between biomass steam boiler and water tank, be connected feed pipe, between storage heater and water tank, be connected condensate pipe, storage heater steam (vapor) outlet is installed control valve, between biomass steam boiler and blowdown waste heat flash vessel, be connected blow-off pipe, between blowdown waste heat flash vessel and water tank, be connected hot-water line.
