Abstract
The utility model discloses a specially-shaped abrasion-resistant economizer with dust easy to clean. The specially-shaped abrasion-resistant economizer comprises a shell and a plurality of heat exchanging pipes, wherein the heat exchanging pipes are distributed in a U shape inside the shell, the heat exchanging pipes are specially-shaped pipes, the cross section of the pipe wall of each heat exchanging pipe is in the shape of an elliptical ring, and protruding specially-shaped teeth are evenly distributed on the outer lateral walls of the heat exchanging pipes. The heat exchanging pipes are made of alloy materials which are high in expansion coefficient, and the outer walls of the heat exchanging pipes are provided with abrasion-resistant anti-corrosion coatings. Due to the fact that the heat exchanging pipes are the specially-shaped pipes and the specially-shaped teeth are arranged on the outer walls of the heat exchanging pipes, the heat exchanging efficiency is improved; due to the fact that the abrasion-resistant anti-corrosion coatings are arranged on the outer walls of the heat exchanging pipes, the abrasion-resistant performance and the anti-corrosion performance of the heat exchanging pipes are improved, and the service life of the heat exchanging pipes can be prolonged.
Description
Technical field
The utility model relates to a kind of heat transmission equipment, relates in particular to the economizer used on a kind of boiler.
Background technology
Economizer in the past is usually by housing and be positioned at its inner heat exchanger tube and form, and the heat exchanger tube outer wall is round and smooth, and little with the flue gas heat exchange area, heat exchange efficiency is low, and energy-saving effect is undesirable; In addition, owing in flue gas, there being coal ash, in the flow of flue gas process, easily exchange heat pipe and cause wearing and tearing, affect the service life of heat exchanger tube.
Summary of the invention
For overcoming the prior art deficiency, it is a kind of wear-resisting, corrosion-resistant that the utility model provides, the wear-resisting easy-to-clean ash economizer of the abnormal shape that heat exchange efficiency is high.
For realizing above-mentioned technical purpose, the utility model is by the following technical solutions: the wear-resisting easy-to-clean ash economizer of a kind of abnormal shape, comprising that housing and some sections within it take the shape of the letter U moves towards the heat exchanger tube distributed, it is characterized in that: described heat exchanger tube is shape tube, the cross section of its tube wall is oval ring, and at lateral wall, is evenly equipped with the heteromorphic teeth of protrusion; Described heat exchanger tube adopts the large alloy material of the coefficient of expansion to make, and its outer wall is provided with the wear-and corrosion-resistant coating.
The beneficial effects of the utility model are: because heat exchanger tube adopts shape tube and outer wall, be provided with heteromorphic teeth, improved heat exchange efficiency, be worth the heat exchanger tube outer wall and be provided with the wear-and corrosion-resistant coating, improved the wear-resisting corrosion resistance that undermines of heat exchanger tube, extend its service life.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is the shape tube structural representation.
In figure, 1, housing, 2, heat exchanger tube, 3, heteromorphic teeth, 4, the wear-and corrosion-resistant coating.
The specific embodiment
Shown in Fig. 1,2, the wear-resisting easy-to-clean ash economizer of a kind of abnormal shape comprises that housing 1 and some sections within it take the shape of the letter U to move towards the heat exchanger tube 2 distributed that it is characterized in that: described heat exchanger tube 2 is shape tube 3, the cross section of its tube wall is oval ring, and at lateral wall, is evenly equipped with the heteromorphic teeth 3 of protrusion; Described heat exchanger tube 2 adopts the large alloy material of the coefficient of expansion to make, and its outer wall is provided with wear-and corrosion-resistant coating 4.
