The energy-saving device has beneficial effects that no acidic condensed water is in the non-condensing chamber, thereby the fitting parts in the non-condensing chamber can be made of common carbon steel, the energy-saving device reduces the manufacturing cost, simultaneously makes a full use of the heat changing of the boiler smoke gas in various time stages, and thereby makes a full use of the residual heat of the boiler.

Description

The boiler smoke condenser is regulated in split type automatic control

One, technical field:

The utility model belongs to the energy saver of field of boilers.

Two, background technology:

Boiler smoke contains Sox, NOx and water vapour, if these materials and together water-soluble, just become acid solution, the corrosion condenser, reduced the service life of equipment, improved maintenance cost, so everybody seeks the waste heat that can make full use of in the boiler smoke, can prevent that again acidic materials from corroding condenser.Some units only notice the etching problem of boiler and reduce the production cost of boiler that do not make full use of the heat of fuel, energy-conservation degree not enough.The waste heat in the flue gas has only been noted utilizing by some units, and does not consider the reduction of cost of manufacture.In sum, these inventions all are useful, but all come with some shortcomings, and therefore will improve existing condensation energy-saving device, and comprehensively its advantage overcomes its shortcoming.

Three, summary of the invention:

The purpose of this utility model is exactly to design a kind of waste heat that can make full use of in the boiler flue, can reduce the split type automatic control of manufacturing cost again and regulate the boiler smoke condenser.

The technical scheme that the utility model technical solution problem is adopted is: in a rectangular case, fix the dividing plate of a tile height less than the housing height, dividing plate is divided into two Room to rectangular case, wherein a Room is the non-condensing chamber, and another chamber is a condensation chamber, and the top of non-condensing chamber has the import of boiler smoke, the top of condensation chamber has the outlet of boiler smoke, the pipe of cold water into is housed on the wall of condensation chamber and goes out the pipe of hot water, the pipe of hot water into is housed on the wall of non-condensing chamber and goes out the pipe of high-temperature water.

The utility model beneficial effect is: do not have sour curdling water in that non-condensing is indoor, so the indoor parts of non-condensing can be made of ordinary carbon steel, reduced cost of manufacture, when reducing manufacturing cost, make full use of the boiler smoke heat exchange of different periods, thereby made full use of the waste heat of boiler, and adapted to the adjusting of boiler load.

Four, description of drawings:

Fig. 1 is a schematic top plan view of the present utility model, and Fig. 2 is that the A of Fig. 1 is to schematic diagram.

Five, the specific embodiment:

Describe details of the present utility model and working condition in detail in conjunction with Fig. 1, Fig. 2.Afterheat utilization in the boiler smoke generally adopts heat exchanger to reach, and heat exchanger is again diversified, has plenty of the employing coil pipe, the wing pipe of the employing that has, the employing finned tube that has, water flowing in these pipes, water is heated, and hot water utilizes again, reaches purpose of energy saving.In energy-conservation, also to improve the service life of energy saver.The utility model will satisfy these two requirements and design.1 li of a rectangular case, fix the dividing plate 3 of a tile height less than the housing height, dividing plate is divided into two Room to rectangular case, wherein a Room is non-condensing chamber 13, another chamber is a condensation chamber 14, the top of non-condensing chamber has the import 2 of boiler smoke, the top of condensation chamber has the outlet 4 of boiler smoke, the into pipe 5 of cold water is housed on the wall of condensation chamber 14, with the pipe 7 that goes out hot water, the heat exchanger 15 that is contained in 14 li of condensation chambers is housed between cold water pipe 5 and the hot-water line 7, the pipe 8 of hot water into is housed on the wall of non-condensing chamber 13 and goes out the pipe 6 of high-temperature water, hot-water line 8 and go out the heat exchanger 15 that is contained in 13 li of non-condensing chambers is housed between the high-temperature conduit 6 equally.Because dividing plate 3, rectangular case 1 is divided into non-condensing chamber 13 and the condensation chamber 14 that two bottoms are connected, non-condensing chamber 13 also is a hot room, moisture requirement can not condense into water in the flue gas in this chamber, moisture requirement is to condense into water in condensation chamber 14 flue gases, also will exchange the heat in the flue gas by heat exchanger 15, and obtain utilizing.Require heat exchanger 15, and the welding material of heat exchanger of 14 li of non-condensing chamber 13 and condensation chambers, the steel plate of doing housing 1 all is different, the parts that the non-condensing chamber is 13 li can be made with ordinary carbon steel, the wall of housing 1 is without preservative treatment, the parts that condensation chamber is 14 li will be with corrosion resistant stainless steel manufacturing, and the steel plate of housing 1 will be done preservative treatment.Why to do like this? because the load of boiler will what be determined according to user's consumption, consumption for a long time, the boiler smoke temperature is just high, consumption boiler smoke temperature after a little while is just low, might will make the moisture content in the flue gas become water in non-condensing chamber 13, water be acid, the parts that the non-condensing chamber is 13 li, housing wall will be corroded, and reduce service life.In order to make non-condensing chamber 13 under any circumstance, moisture in the flue gas can not become water, will improve the temperature of condensation chamber, so between the pipe 8 of pipe 7 that goes out hot water on condensation chamber 14 walls and the enterprising hot water of non-condensing chamber 13 walls, water temperature regulation device 9 is housed, control valve 12 is housed on the water temperature regulation device, on the pipe 8 that advances hot water, thermometric spare 11 is housed, thermometric spare 18 is housed on the wall of non-condensing chamber 13.The action of control valve 12 is the temperature that record according to thermometric spare 11,18, passes on the control valve 12 by temperature sensor, and the action of order control valve.9 li heaters 10 that helix tube is housed of water temperature regulation device have hot water inlet 19 and hot water outlet 20 on the heater, the effect of this heater 10 is that the water vapour in the flue gas that guarantees in non-condensing chamber 13 can not condense into water.In 2 sections of the imports of flue gas, thermometric spare 16 is housed, in 4 sections of the outlets of flue gas, thermometric spare 16 is housed.These thermometric spares be for the ruuning situation of observing boiler set.
