Abstract

The utility model discloses a parallel-level-arrangement biomass fuel boiler economizer, consisting of multiple groups of U-shaped pipe rows and anti-abrasion tiles, wherein multiple U-shaped pipe rows in each group are used for cooling; the U-shaped pipe rows in each group are arranged in a parallel and level manner and distributed in sequence; the distance among the pipe rows is 45-50mm; smoke flows in a linear manner; and all pipes of the U-shaped pipe rows are protected by the anti-abrasion tiles. Due to the structure of the economizer, the circulation area is increased, the flowing speed is reduced, and the abrasion points are dispersed to each U-shaped pipe. The economizer can avoid the phenomenon that one pipe is abraded concentratedly, is beneficial to prolonging the service life thereof and maintaining the normal circulation of the smoke of a boiler, and additionally, is convenient to the hand cleaning when the boiler is stopped for maintenance.

Description

A kind of biomass fuel boiler economizer of concordant arrangement

[technical field] the utility model relates to a kind of boiler component, is a kind of biomass fuel boiler economizer of concordant arrangement specifically.

[background technology] biomass fuel such as branch, crops tangerine bar, discarded firewood etc. are renewable data, all are taken as offal treatment in the past, and this not only will spend a large amount of disposal costs, and more it's a pity has wasted valuable heat resource and contaminated environment; And current commonly used non-renewable data such as oil, natural gas, fire coal, few day by day because of these resources again, price constantly promotes, so many scientific workers and government organs, all making great efforts to explore how to make full use of these reproducible energy source materials, in order to replenish or to substitute those non-renewable energy resources that reduce day by day; At present; the wearing and tearing of the economizer of each biomass fuel boiler are quite serious; its main cause is that a plurality of pipe rows arrange for stagger arrangement; and row-to-row distance is too little; easy dust stratification flows flue gas to be serpentine bend to rise and fall in pipe row, make to protect watt can only protect first; and what wearing and tearing occur all is second, third root of not protecting, so it has a strong impact on the long-term operation continuously of boiler.

[summary of the invention] for overcoming the above-mentioned defective of existing biomass fuel boiler economizer, the utility model provides a kind of biomass fuel boiler economizer of concordant arrangement, to reduce the wearing and tearing of flue gas to economizer, prolongs the service life of economizer.

For solving its technical problem; the technical solution adopted in the utility model is: this economizer is made up of many groups more than every group U type pipe row and wearing-resistant tile that is used to cool off; every group all concordant being arranged as along row of U type pipe row arranged; and the distance between pipe row is 45-50mm; making flue gas is that orthoscopic flows, and every group of U type pipe row's every U type Guan Jun is under the protection of wearing-resistant tile.

Compared with prior art, the beneficial effects of the utility model show: because the many groups of pipe rows that are made up of many U type pipes of economizer, all concordant being arranged as along row arranged, and the distance between pipe row more than 45-50mm, has increased the circulation area of economizer at least, and flow velocity reduces, make wear point evenly be dispersed to every U type pipe, can avoid concentrating the phenomenon of pipe wearing and tearing, in the service life that helps improving economizer, help the normal circulation of boiler smoke; In addition, when shutdown maintenance, also be convenient to the labor cleaning.

[description of drawings] further specifies the utility model below in conjunction with drawings and Examples.

Fig. 1 is the positional structure schematic diagram of the utility model in the biomass fuel boiler system.

Fig. 2 is one group of U type of the utility model pipe row's a structural representation.

Among the figure: 1, combustion chamber, 2, feed pipe, 3, feed bin, 4, boiler body, 5, high temperature superheater, 6, blast cap pipe, 7, level crosses flue, 8, low temperature superheater, 9, economizer, 10, deduster, 11, chimney, 901, water inlet, 902, U type pipe bend, 903, delivery port.

[specific embodiment] is referring to accompanying drawing: including combustion chamber 1, feed pipe 2, feed bin 3, boiler body 4, high temperature superheater 5, blast cap pipe 6, level is crossed flue 7, low temperature superheater 8, economizer 9 is in the biomass fuel boiler system of deduster 10 and chimney 11, described economizer 9 is arranged by framework through being welded by many groups U type pipe, each organizes U type pipe row and neat the arrangement, and every group of U type pipe row is welded by framework by multilayer U type pipe row, and the distance between each layer U type pipe row is 45-50mm, making flue gas is that orthoscopic flows, and every layer of U type pipe row is connected in series from beginning to end by many U type pipes and forms, and its end is provided with water inlet 901, the other end is provided with delivery port 903, the U type elbow 902 of each U type pipe and neat the arrangement.During work as long as connect cooling water in the water inlet, but connect just operate as normal of the draining circulatory system at the delivery port place.
