Utility model content
For solving this problem existed in above-mentioned technology, the utility model provide one be convenient to discharge burnt gas, alleviate heating tube corrosion, prevent detonation can be explosion-proof economizer.
The utility model is for solving the problems of the technologies described above, the technical scheme adopted is: a kind of can be explosion-proof economizer, comprise housing, described housing lower end is provided with smoke inlet, upper end is provided with exhanst gas outlet, be positioned at the gripper shoe that housing is arranged with two pieces of vertical directions, each gripper shoe and inner walls form diversion cavity, heating chamber is formed between two pieces of gripper shoes, two pieces of gripper shoes connect heating tube, described heating tube is distributed in housing in snakelike from top to bottom, the part that heating tube is positioned at heating chamber caves in smoke inlet direction, and the U-shaped elbow in the knee at two ends is in diversion cavity, gripper shoe on vertical direction between adjacent two U-shaped elbows is provided with the pod apertures being communicated with heating chamber and diversion cavity.
As further setting, described heating tube outer wall is provided with rounded fin, and each described fin has guiding gutter along heating tube length direction.
As further setting, between fin adjacent on described heating tube, there is certain spacing.
As further arranging again, described heating tube upper end connects outlet pipe, and lower end connects into water pipe.
As further arranging, the part that described heating tube is positioned at heating chamber is V-shaped to lower recess, and groove least significant end is circular arc chamfering.
Income effect: there is several significant advantage relative to prior art the utility model: 1, heating tube is snakelike distribution, heating surface is large, contributes to the heat fully absorbing flue gas, improves exchange capability of heat; 2, heating tube outer wall is provided with fin, can reduce the deflection of heating tube by high temperature deformation; 3, be provided with diversion cavity in economizer, be convenient to the burnt gas of discharging deposition in economizer; 4, go out to be provided with pod apertures at the U-shaped elbow that heating tube is bending, the local flue gas that easily deposition burning is discarded is discharged, slow down the corrosion rate of heating tube, improve the service life of economizer; 5, heating tube outer wall is provided with guiding gutter, and the heating tube being positioned at heating chamber caves in smoke inlet direction, gripper shoe is provided with pod apertures, the flue gas between heating tube gap is made to flow to diversion cavity towards the incline direction of heating tube, flue gas is flowed to the both sides of economizer uniformly, avoiding to concentrate is trapped in the middle part of economizer, blocks the circulation that flue affects flue gas; 6, U-shaped elbow is in diversion cavity, protects heating tube and easily corrodes impaired position, improve the security performance of economizer.

Detailed description of the invention
Elaborate to embodiment of the present utility model below in conjunction with accompanying drawing, the present embodiment, premised on technical solutions of the utility model, give detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
As shown in Figure 1, a kind of can be explosion-proof economizer, comprise housing 1, described housing 1 lower end is provided with smoke inlet, upper end is provided with exhanst gas outlet, coal smoke flows in housing 1 from bottom to up, housing 1 side connects the gripper shoe 10 of two pieces of vertical directions, gripper shoe 10 is mutually vertical with housing 1 bottom surface, each gripper shoe 10 forms two diversion cavity 5 with housing 1 inwall, diversion cavity 5 is positioned at housing 1 both sides, diversion cavity 5 inner wall smooth, upper end open is communicated with exhanst gas outlet, be convenient to the burnt gas of discharging deposition in economizer, heating chamber 2 is formed between two pieces of gripper shoes 10, two pieces of gripper shoes 10 connect heating tube 4, as Fig. 2, shown in Fig. 3, heating tube 4 outer wall is provided with rounded fin 8, each described fin 8 has guiding gutter 9 along heating tube 4 length direction, owing to containing a large amount of flying dusts in flue gas, the heating surface of economizer inside is made to be subject to serious wearing and tearing, gap between tube and tube is reduced by the structural design of heating tube 4, fin 8 having guiding gutter 9 makes flue gas have each small-sized flue, flue gas concentration is tending towards even, when flue gas flows through fin 8 position, flue gas is concentrated from guiding gutter 9 to diversion cavity 5, alleviate flue gas washing away heating tube, also mitigate the wearing and tearing of heating tube, because flue-gas temperature is higher, heating tube 4 very easily deforms under being in hot conditions for a long time, fin 8 also to a certain degree alleviate the deflection that heating tube 4 is heated.
Described heating tube 4 is distributed in housing 1 in snakelike from top to bottom, the snakelike distribution of heating tube 4 makes heating surface large, contribute to the heat fully absorbing flue gas, improve exchange capability of heat, the part that heating tube 4 is positioned at heating chamber 2 caves in smoke inlet direction, and the elbow that the knee at two ends is U-shaped, U-shaped elbow is in diversion cavity 5, gripper shoe 10 on vertical direction between adjacent two U-shaped elbows is provided with pod apertures 3, described pod apertures 3 is communicated with heating chamber 2 and diversion cavity 5, the flue gas that the sunk structure of heating tube 4 middle part makes flows to the both sides of economizer uniformly, avoiding to concentrate is trapped in the middle part of economizer, block the circulation that flue affects flue gas, heating tube 4 both sides of snakelike distribution are elbow, but due to its warp architecture, outside elbow, tube wall is thinning and reduce tube wall strength, simultaneously easily to deposit flue gas very large to the abrasion and corrosion of elbow at warp architecture place, elbow is increased pod apertures 3 by the structural design of this device, and elbow is in diversion cavity 5, alleviate elbow wearing and tearing, add the service life of heating tube 4.
For the ease of the safe and reliable operation of economizer, described heating tube 4 upper end connects outlet pipe 7, and lower end connects into water pipe 6, and in heating tube 4, water flows from bottom to top, the bubble may releasing a small amount of gas and steam formation in water is easy to get rid of, and is not easy to produce stagnate and block.
It is prior art that the utility model does not describe part.
