Description

Economizer

Technical field

It the utility model is related to thermal power plant boiler waste heat recovering energy conserving apparatus field, more particularly to a kind of economizer.

Background technology

At present, the economizer that thermal power plant boiler uses is generally based on tubular type, fin tube type.Its condensate is walked in pipe, cigarette Gas is blown by blower fan plunders pipeline to realize heat exchange, is exchanged heat between flue gas and condensate using cross-flow.

However, economizer of the prior art needs a large amount of tubing, overall floor space is big, in use, saves The coiled pipe of coal device is together with welding box body, and when part, snakelike body is occurred corrosion failure phenomenon by the erosion of flue gas When, the situation of economizer leak is easily caused, and whole economizer is changed, need higher cost.

Utility model content

The purpose of this utility model is to provide a kind of economizer, and having can be to the snake of the part economizer of corrosion phenomenon occurs Shape body is changed, reduce replacement cost the advantages of.

Above-mentioned technical purpose of the present utility model technical scheme is that：

A kind of economizer, including bearing, the water inlet pipe and outlet pipe being arranged on bearing, and it is arranged at water inlet pipe and water outlet Snakelike body between pipe, the snakelike body include the straight member and bool of integrally connected, one end of the snakelike body Straight member be connected with water inlet pipe by ring flange, the straight member of the other end of the snakelike body passes through with outlet pipe；It is described Sliding part is provided with bool, the sliding part includes base and roller, is offered on the bearing for coordinating sliding part Chute, the roller abuts with the bottom of chute.

Using said structure, water inlet pipe, outlet pipe that the both ends straight member of snakelike body is connected with it respectively are flange Disk connects, and when the snakelike body in part is by flue gas corrosion, can separate two ring flanges, to realize the snake for removing the partial corrosion The purpose of shape pipe.And when this section of snakelike body is taken out, along chute, and the base by being cooperated with chute and Roller, this section of snakelike body is translated out, reduce the frictional force between snakelike body and bearing, the effect for reach laborsaving, easily taking out Fruit, the replacing to part coiled pipe is facilitated, reduce replacement cost.In use, the flue gas outside coiled pipe body can be compared with Fully to transfer heat to the water that snakelike tubular body passes through, contribute to the recycling of heat energy, reach energy-saving coal amount Purpose.

More preferably：The first slot is offered on the bearing, projection, the projection are provided with the straight member On be inserted with fixture, the fixture includes the first grafting article, barrier rib arranged in a crossed manner in the first grafting article, is sheathed on the Spring outside one grafting bar, the first grafting bar and the clamp nut abutted with bearing are bolted in, the first grafting bar is worn By the way that in projection and the first slot of insertion, one end of the spring abuts with clamp nut and the other end abuts with projection.

Using said structure, by the mutual cooperation of spring, clamp nut, barrier rib, the first grafting bar is set to connect projection With the first slot, and then connect snakelike body and bearing, contribute to it is vertically upper to snakelike body produce it is spacing and fixed Effect, add the overall stability of the economizer to be formed.

More preferably：The fixture also includes the second grafting bar being connected on barrier rib, first grafting Bar, the second grafting bar are be arranged in parallel, and the second slot is offered in the projection, and the second grafting bar is inserted in the second slot.

Using said structure, the second grafting bar is inserted in the second slot, with the cooperation phase of the first grafting bar and the first slot Mutually contact, and then increase fixture to the connection effect of snakelike body, reduce in installation process, snakelike body occurs along vertical The possibility of skew on direction.

More preferably：Positive stop strip is provided between the two neighboring parallel bool, the positive stop strip fixes Between two neighboring base.

Using said structure, in installation process, positive stop strip can make to be parallel to each other between two sections of adjacent snakelike bodys, and And reduce the possibility that the skew on vertically occurs for snakelike body.

More preferably：Connected between the positive stop strip and base by cutting.

Using said structure, the connection integrity between positive stop strip and base is added, reduces the possibility that positive stop strip drops. And in installation process, between adjacent two sections of snakelike bodys, base and positive stop strip are attached by a grafting bar, The snakelike body of adjacent two sections can be made to keep good paralleling effect, stability when increase uses.

More preferably：The end face cross section of the base is "T"-shaped.

Using said structure, reduce during installation or the snakelike body of disengaging section, base and chute phase occur The possibility mutually separated, add stability when the snakelike body that part is corroded is removed replacing.

More preferably：Stopper slot is additionally provided with the base, the roller coordinates with stopper slot.

Using said structure, stopper slot cooperates with roller, further reduces snakelike body and is sent out along stopper slot both sides The possibility of raw skew, also plays and spacing effect is carried out to snakelike body.

In summary, the utility model has the advantages that：

1. by the mutual cooperation of ring flange, fixture, sliding part, can be achieved to enter the snakelike body in part for occurring corroding Row dismounting and replacing, reduce replacement cost；

2. the mutual cooperation of chute, stopper slot and base, roller, add stability when installation and dismounting.
