Abstract
The utility model discloses a drainable coal economizer. The drainable coal economizer comprises upper concentration pipes, coal economizer straight pipes, lower concentration pipes and drainage pipes, wherein the coal economizer straight pipes are arranged between the upper concentration pipes and the lower concentration pipes; and the lower concentration pipes are communicated with the drainage pipes through connecting pipes. Due to the adoption of straight pipes, the drainable coal economizer is simple and convenient to manufacture and compact in structure; the residual water in the drainable coal economizer can be very conveniently drained; straight pipe dedusting only requires vibrating and knocking without installation of anti-wearing sheets; compared with dedusting by steam blowing, the straight pipe dedusting is energy-saving and cost-saving; and since lifting lugs are arranged additionally, the drainable coal economizer is convenient to lift and install.
Description
Technical field
The utility model relates to the boiler technology field, especially relates to a kind of hydrophobic type economizer.
Background technology
Existing economizer uses snakelike seamless steel pipe to make, and utilizes the waste heat heating boiler feedwater of boiler tail flue gas, reduces exhaust gas temperature, improve boiler thermal output, fuel savings, and improve the temperature difference heat stress that joins between feedwater and the drum wall, improved the quality of water.Economizer is usually placed in the flow through shaft, and the coiled pipe horizontal positioned is beneficial to draining, and for the ease of maintenance, coiled pipe group height has certain restriction, also should be divided into several pipe groups if the pipe group is highly excessive, and needs slot milling between the pipe group.
Existing economizer has the following disadvantages: the requirement for height to flow through shaft is very high, the lifting trouble; The version of coiled pipe makes the installation trouble of anti-abrasive disc and the interior remaining moisture content of pipe be difficult to remove, and is not corrosion-resistant.
The utility model content
Technical problem to be solved in the utility model provides a kind of hydrophobic type economizer, and it gets rid of the residual water in the economizer very easily, and make easy, cost is low.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of hydrophobic type economizer, comprise concentrate tube, economizer straight tube, following concentrate tube, drain pipe, described economizer straight tube is located between concentrate tube and the following concentrate tube, and described concentrate tube down is connected by tube connector with drain pipe.
Be connected by bilge main between described tube connector and the drain pipe.
The described concentrate tube of going up is provided with one group of hanger.
The utility model compared with prior art has the following advantages: adopt the straight tube form, make easyly, compact conformation can be got rid of the residual water in the economizer very easily; The straight tube ash disposal only need be shaken to beat and be got final product, and anti-abrasive disc need be installed, and steam soot blowing is saved the energy and cost relatively; Set up hanger, it is easy for installation to sling.
Description of drawings
Below the expressed content of each width of cloth accompanying drawing of this specification and the mark among the figure are briefly explained:
Fig. 1 is the utility model hydrophobic type economizer organigram.
Among the figure: 1. go up concentrate tube, 2. the economizer straight tube, 3. descend concentrate tube, 4. tube connector, 5. bilge main, 6. drain pipe, 7. hanger.
The specific embodiment
Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present utility model is described in further detail.
As shown in Figure 1, a kind of hydrophobic type economizer comprises concentrate tube 1, economizer straight tube 2, following concentrate tube 3, drain pipe 6, and wherein, economizer straight tube 2 is located between concentrate tube 1 and the following concentrate tube 3, and following concentrate tube 3 is connected by tube connector 4 with drain pipe 6.
Further, be connected by bilge main 5 between tube connector 4 and the drain pipe 6, compact conformation is made easy.
On last concentrate tube 1, be provided with three hangers 7 side by side, by 7 of the hangers whole economizer of slinging, easy for installation.
By reference to the accompanying drawings the utility model has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that design of the present utility model and technical scheme carry out; or without improving design of the present utility model and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
