Abstract
The invention relates to a heat recovery boiler with a soot blowing function. The heat recovery boiler with the soot blowing function comprises an economizer and a smoke evaporator. The economizer is provided with a smoke inlet, a smoke outlet, a water inlet and a water outlet. The smoke evaporator is provided with a smoke outlet, a water inlet, a steam outlet and a soot blower. The smoke inlet of the economizer is connected with the smoke outlet of the smoke evaporator. The water outlet of the economizer is connected with the water inlet of the smoke evaporator. The steam outlet of the smoke evaporator is connected with the soot blower which is connected with the economizer. The heat recovery boiler with the soot blowing function utilizes self-produced steam to blow soot, is energy-saving and environment-friendly and improves boiler efficiency.
Description
Technical field
The present invention relates to a kind of waste heat boiler that blows grey function that has.
Background technology
What commonly use in the waste heat boiler is flue type waste heat boiler, and the distinguishing feature of flue type waste heat boiler is, it has preheater, superheater, flue gas evaporator and economizer etc. in a flue.Economizer is the important component part of boiler plant, and it utilizes fume afterheat that boiler feedwater is heated, and reduces thermal loss, saves coal, improves boiler efficiency.Cast iron type wing economizer, because surperficial fin is more, flue gas resistance is larger, easily dust stratification.When boiler feed temperature is low, when coal-fired moisture was large, the economizer surface is easy dewfall again, impels dust stratification constantly to thicken.This economizer is without blowing grey facility, and the time one is long, and flue seriously stops up, and affects boiler efficiency.
Summary of the invention
The technical problem to be solved in the present invention is: for, the invention provides a kind of cast iron type economizer.
The technical solution adopted for the present invention to solve the technical problems is: a kind of have a waste heat boiler that blows grey function, have economizer and flue gas evaporator, described economizer has into mouth, outlet flue, water inlet and delivery port, described flue gas evaporator has outlet flue, water inlet and steam (vapor) outlet, also has soot blower, the mouth that advances of described economizer is connected outlet flue and is connected with flue gas evaporator, the delivery port of described economizer is connected water inlet and is connected with flue gas evaporator, the steam (vapor) outlet of described flue gas evaporator is connected with soot blower, and described soot blower is connected with economizer.
Described soot blower is air blast.
The invention has the beneficial effects as follows that the present invention has the waste heat boiler that blows grey function, utilize the steam soot blowing that self produces, energy-conserving and environment-protective improve boiler efficiency.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the structural representation that the present invention has the optimum embodiment of waste heat boiler that blows grey function.
Among the figure 1, economizer, 2, flue gas evaporator, 3, soot blower.
The specific embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
As shown in Figure 1, a kind of have a waste heat boiler that blows grey function, has economizer 1 and flue gas evaporator 2, and economizer has into mouth, outlet flue, water inlet and delivery port, and flue gas evaporator has outlet flue, water inlet and steam (vapor) outlet; Also have soot blower 3, the outlet flue that mouth is connected with flue gas evaporator that advances of economizer 1 connects, and the water inlet that the delivery port of economizer 1 is connected with flue gas evaporator connects, and the steam (vapor) outlet of flue gas evaporator 2 is connected connection with soot blower, and soot blower 3 is connected connection with economizer; Soot blower 3 is air blast.
Take above-mentioned foundation desirable embodiment of the present invention as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this invention technological thought, carry out various change and modification fully.The technical scope of this invention is not limited to the content on the specification, must determine its technical scope according to the claim scope.
