Abstract
The utility model relates to an Isa furnace screen type evaporator which comprises an inlet header, an outlet header and a fin pipe set. The inlet ends of the fin pipe set are connected with the inlet header, the outlet ends of the fin pipe set are connected with the outlet header, the upper end and the lower end of the fin pipe set are connected with all fin pipes through an upper connection pipe and a lower connection pipe, a rapping apparatus is arranged close to the upper end of the fin pipe set, and the rapping apparatus is connected with the upper connection pipe and the fin pipes through a connection heating face of the rapping apparatus. The fin pipe structure is adopted in the Isa furnace screen type evaporator, the mechanical rapping apparatus is arranged to prevent slags and dust, and environment pollution is reduced.
Description
Technical field
The utility model relates to the heat-exchange system of heat energy in a kind of Sa stove recovered flue gas that ends, and particularly relates to a kind of Chinese mugwort Sa stove screen formula evaporimeter.
Background technology
At Chinese mugwort Sa stove screen formula evaporimeter position, flue-gas temperature temperature is very high, and typical temperature reaches more than 1200 ℃.In order further to absorb the radiant heat of flue gas, reduce the floor space of boiler, screen formula evaporimeter arises at the historic moment.
Manufacturer at home, does not formerly shield the precedent that formula evaporimeter uses, but along with the development in epoch, and domestic minority producer utilizes foreign technology to copy screen formula evaporimeter, and the light pipe screen formula evaporimeter of solid matter is brought into use.But although this structure is more advanced, in Chinese mugwort Sa stove, the easy slagging scorification dust stratification of this structure, lime-ash has not only reduced the heat-transfer effect of heating surface, corroding metal, and also its ash content still causes the root of environmental pollution.
Utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, and a kind of Chinese mugwort Sa stove screen formula evaporimeter that can prevent slagging scorification dust stratification is provided.
For achieving the above object, technical solution adopted in the utility model is as follows.
A Chinese mugwort Sa stove screen formula evaporimeter, comprises import header, outlet header and extended surface tube group, and the entrance point of described extended surface tube group is connected with described import header, and the port of export of described extended surface tube group is connected with described outlet header; The two ends up and down of described extended surface tube group are connected every extended surface tube by top tube connector with bottom tube connector respectively; Upper end near described extended surface tube group is provided with rapping apparatus, and described rapping apparatus connects heating surface by rapping apparatus and connects described top tube connector and described extended surface tube.
Further, described rapping apparatus connection heating surface and described extended surface tube are welded to connect.
Further, the top of described extended surface tube group is provided with ceiling seal closure.
Further, described rapping apparatus is arranged on described ceiling seal closure.
The beneficial effects of the utility model are: Chinese mugwort Sa stove screen formula evaporimeter of the present utility model adopts extended surface tube structure, and mechanical shaking device is set, and has avoided slagging scorification dust stratification, has alleviated environmental pollution.
Accompanying drawing explanation
Fig. 1 is the structural representation of Chinese mugwort Sa stove screen formula evaporimeter of the present utility model.
Fig. 2 is the partial enlarged drawing of S part in Fig. 1.
In figure, 1-import header, 2-top tube connector, 3-ceiling seal closure, 4-rapping apparatus connects heating surface, 5-rapping apparatus, 6-outlet header, 7-extended surface tube group, 8-bottom tube connector.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is described in further detail.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Chinese mugwort Sa stove screen formula evaporimeter of the present utility model as shown in Figure 1, comprises import header 1, outlet header 6 and extended surface tube group 7, and the entrance point of extended surface tube group 7 is connected with import header 1, and the port of export of extended surface tube group 7 is connected with outlet header 6; The two ends up and down of extended surface tube group 7 are connected every extended surface tube by top tube connector 2 with bottom tube connector 8 respectively; The top of extended surface tube group 7 is provided with ceiling seal closure 3, and the effect of ceiling seal closure 3 is that flue gas and air are separated; Upper end near extended surface tube group 7 is provided with rapping apparatus 5, and rapping apparatus 5 is arranged on described ceiling seal closure 3, and rapping apparatus 7 connects heating surface 4 by rapping apparatus and connects top tube connector 2 and extended surface tube.As preferably, rapping apparatus connects heating surface 4 and is welded to connect with extended surface tube.
Fig. 2 is the partial enlarged drawing of S part in Fig. 1, as shown in Figure 2, between extended surface tube, by fin, connects, and fin is positioned at the both sides of extended surface tube.
Recirculated water is entered by import header 1, by top tube connector 2, bottom tube connector 8, extended surface tube group 7, is connected heating surface 4 heat exchange with rapping apparatus, completes the laggard inlet/outlet header 6 of heat exchange.When having slagging scorification dust stratification, because connecting heating surface, rapping apparatus is connected with extended surface tube bond pads, and what equal rapping is extended surface tube group, is naturally shed to bottom ash handling equipment during slagging scorification dust stratification,
The foregoing is only preferred embodiment of the present utility model, be not used for limiting practical range of the present utility model; If do not depart from spirit and scope of the present utility model, the utility model is modified or is equal to replacement, all should be encompassed in the middle of the protection domain of the utility model claim.
