Abstract
The present invention proposes that a kind of wall-hung boiler is changed the method for condensing, more particularly to a kind of condensing heat exchanger and hot water heat exchanger and the thinking deposited by on-condensing.Realizing the implementation system of the technology of the present invention requirement mainly includes the external fixed condensing heat-exchanger rig that condensing heat exchanger, triple valve, hot water exchanger, blower fan are constituted.Before the high-temperature flue gas discharge of on-condensing wall-hung boiler, it is passed through external fixed condensing heat-exchanger rig, Mist heat recovering, while condensing flue gas high temperature vapor and partial contamination thing, improve boiler efficiency and pollutant emission standard.By condensing heat exchanger and hot water heat exchanger and deposit, make wall-hung boiler in only heating, only hot-water supply or simultaneously can recovery section fume afterheat in the case of heating and hot-water supply.By external condensation heat exchange device, the cost that on-condensing wall-hung boiler replaces with condensing type wall-mounted furnace is reduced, the investment payback time is shortened.
Description
Technical field
The present invention relates to a kind of method that wall-hung boiler is changed condensing by on-condensing, belong to the raising effect of civil boiler equipment
Rate field and cleaning discharge field.
Background technology
Wall-hung boiler have it is convenient install, it is safe and efficient the features such as, there is very big market in domestic heating field.
Common wall hanging fire grate cigarette temperature is general more than 120 DEG C, and causing smoke evacuation to take away, heat loss is bigger than normal, and pollutant emission refers to
Mark is higher, and the thermal efficiency is typically 85% or so；Condensing type wall-mounted furnace can utilize smoke exhaust heat heating backwater and feedwater, drop
Low exhaust gas heat loss becomes estranged pollutant discharge amount, and the thermal efficiency is typically 100% or so.
Condensing type wall-mounted furnace is more efficient and more cleans, but because replacing condensing type wall-mounted furnace cost is higher, current family expenses
On-condensing wall-hung boiler still occupies significant proportion in heating market, this waste for resulting in the energy and the pollution of environment, therefore sets
A kind of method that wall-hung boiler changes condensing by on-condensing is counted just to be particularly important.
The content of the invention
The method that wall-hung boiler proposed by the present invention is changed condensing by on-condensing, it is therefore an objective to change on-condensing wall with low cost
Extension stove is condensing type wall-mounted furnace, to reach effect that is cost-effective, improving efficiency and cleaning discharge.
Realize the present invention is to solve the problems, such as the technical scheme that prior art is used：
The main external fixed condensing heat-exchanger rig constituted including triple valve, condensing heat exchanger, hot water exchanger, blower fan.
Described reduction flue gas heat loss and the method for pollutant discharge amount are in the external condensing of on-condensing wall-hung boiler
Heat-exchanger rig, reduces flue-gas temperature, and backwater and feed temperature are improved, and part pollutant condenses and focused in flue gas.
The external fixed condensing heat-exchanger rig is arranged on the chimney end of on-condensing wall-hung boiler, its backwater import and heating
Backwater outlet connection, backwater outlet is connected with the heating water return import of on-condensing wall-hung boiler, and feed-water inlet connects with cooling water outlet
Connect, feedwater outlet is connected with the cooling water inlet of on-condensing burnt gas wall hanging furnace.
The external fixed condensing heat exchanger has condensate discharge outlet.
The triple valve, may control whether that heating water return or cold water enter external fixed condensing heat-exchanger rig.
The triple valve, can be co-operated with non-condensing wall-hung boiler valve, and control constitutes condensing type wall-mounted furnace and only supplied
Hot water, only heating or simultaneously heating and hot-water supply.
The material of the condensing heat exchanger is corrosion-resistant steel, or easily changes cheap material, or is selected according to smoke components
Unlike material.
The hot water exchanger can ensure that device heats in only hot-water supply, only or heated simultaneously and hot-water supply condition
Under can recovery section fume afterheat.
The material of the hot water exchanger is corrosion-resistant steel, or easily changes cheap material.
The blower fan, it is ensured that flue gas overcomes the smooth circulation of resistance.
Brief description of the drawings
The following drawings is only intended to, in making schematic illustration and explanation to the present invention, not delimit the scope of the invention.Fig. 1

The heating water return outlet of thermal.
Embodiment
With reference to Fig. 1 it can be seen that the mounting means of external fixed condensing heat-exchanger rig is：By its gas approach and non-condensing wall
Hang stove chimney to connect, backwater import is connected with heating water return outlet, backwater outlet and the heating water return of on-condensing wall-hung boiler enter
Mouth connection, feed-water inlet is connected with cooling water outlet, and feedwater outlet is connected with the cooling water inlet of on-condensing burnt gas wall hanging furnace.
The method implementation process that wall-hung boiler proposed by the present invention changes condensing by on-condensing is：By controlling triple valve to make
Boiler blow-down water enters condensing heat exchanger, and the confession of non-condensing wall-hung boiler is entered after wall-hung boiler chimney high temperature flue gas
Warm backwater import, its cyclic part in external condensation heat exchange device can pass through hot water exchanger and feedwater exchanges heat, and improves
Wall-hung boiler cooling water inlet temperature, higher efficiency utilizes fume afterheat, and completing on-condensing wall-hung boiler with this changes condensing type wall-mounted furnace
Purpose.
Embodiment of the present invention, its core concept is：The high-temperature flue gas of on-condensing wall-hung boiler discharge, by condensation
Partial heat is carried in formula heat exchanger, flue gas to be absorbed by low temperature heating backwater in condenser, is reduced heat loss due to exhaust gas, is improved
Boiler efficiency；The high-temperature vapor carried in flue gas because temperature reduce condense into water, partial contamination thing dissolve into condensed water with
Liquid form is excluded, and reduces boiler pollutant discharge capacity；It is original non-without changing because external external fixed condensing heat-exchanger rig
Condensing type wall-mounted furnace, makes improvement cost more much lower than purchase condensing type wall-mounted furnace, cost that cost is low and easy short time recoups the investment.
The embodiment, can control only heating, only hot-water supply or simultaneously heating and hot-water supply by control valve,
Because the presence of hot water exchanger, make device under three circumstances can recovery section fume afterheat.
The embodiment, can be by changing heat exchanger material, it is adaptable to the wall-hung boiler of different fuel.
