Abstract
The utility model relates to a device for spraying and recycling waste heat of boiler exhaust gas. The device is characterized in that a spraying device is arranged at the upper part of a tail flue behind a dust collector; a water accumulating groove is formed in the bottom of the tail flue; the spraying device comprises nozzles and a water inlet pipe; the nozzles are uniformly formed in the form of a straight line and use water curtain type water spraying modes; the water inlet pipe is connected with a water outlet pipe of a water source heat pump evaporator; and the water accumulating groove is connected with an inlet pipe of the water source heat pump evaporator by an outlet pipe. Compared with the prior art, the device for spraying and recycling the waste heat of the boiler exhaust gas, provided by the utility model, has the advantages as follows: as the waste heat of the boiler exhaust gas is recycled and the spraying device, the discharging temperature of boiler flue gas is reduced, heat pollution of the boiler in operation is reduced and the waste heat of the boiler exhaust gas is sufficiently used for hot water production.
Description
Technical field
The utility model relates to the boiler exhaust gas recovery and utilization technology, particularly relates to adopting spray equipment recovery boiler using waste heat from tail gas, and utilizes water resource heat pump to carry out the device of hot water production.
Background technology
At present, common boiler tail flue gas utilization is mainly used in air preheater (heating boiler combustion air), economizer modes such as (raising boiler feed temperatures).Equally also have the application of heat pipe heat exchanger to reclaim the boiler exhaust gas waste heat, but the method also majority be used to reduce the boiler energy consumption, same majority is applied as the raising of boiler combustion with air or feed temperature, minority is applied in to other technology drying effect is provided.In energy savings, when improving energy utilization rate, the heat recovery technology is very important.
Summary of the invention
The utility model has overcome deficiency of the prior art, and a kind of device that sprays the recovery boiler using waste heat from tail gas is provided, and this device adopts spraying technique recovery boiler using waste heat from tail gas, and is used for water resource heat pump production hot water.
In order to address the above problem, the utility model adopts following technical scheme:
The device of spray recovery boiler using waste heat from tail gas is characterized in that the back-end ductwork top behind deduster is provided with spray equipment, and the back-end ductwork bottom is provided with water storage tank; Described spray equipment is made up of nozzle and water inlet pipe, and nozzle is linearly evenly arranged the mode that adopts cascade shape water spray, and water inlet pipe is connected with the water source heat pump evaporator outlet pipe; Described water storage tank is connected with the water source heat pump evaporator inlet tube through fairlead.
Compared with prior art, the beneficial effect of the utility model is: through spray equipment recovery boiler using waste heat from tail gas, reduce the boiler smoke exhaust temperature, reduce the boiler operatiopn thermal pollution, make full use of the boiler exhaust gas waste heat and carry out hot water production.

The specific embodiment
Be described further below in conjunction with the specific embodiment of accompanying drawing the utility model.
The device of spray recovery boiler using waste heat from tail gas, back-end ductwork 2 tops behind deduster are provided with spray equipment 3, and back-end ductwork 2 bottoms are provided with water storage tank 4; Described spray equipment 3 is made up of nozzle and water inlet pipe, and nozzle is linearly evenly arranged the mode that adopts cascade shape water spray, and water inlet pipe is connected with water source heat pump evaporator outlet pipe 8; Described water storage tank 4 is connected with water source heat pump evaporator inlet tube 9 through fairlead 5.
The nozzle of spray equipment linearly evenly distributes, and cascade shape water spray makes full use of poor to flow path direction that flue gas makes progress, cold water sprays downwards, utilizes cold water that the tail flue gas of dedusting is carried out spraying cooling, and reaches the purpose that covers whole flue radial section.
The shower water of accomplishing heat exchange returns spray equipment through water source heat pump evaporator outlet pipe 8 by diameter 159mm pipeline, repeats spray, accomplishes the flue gas waste heat recovery circulation.
Cold water gets into the water resource heat pump condenser from cold water inlet 7, utilizes the surplus temperature of boiler exhaust gas, improves cold water temperature, and hot water is drawn from hot water outlet 6, realizes hot water production.
