Abstract
The invention relates to a hot water heat exchanger for a cement kiln. A heat exchange cover (1) covers the outer part of a cement kiln body (2), a heat exchanger channel (3) is arranged between the heat exchange cover (1) and the cement kiln body (2), one end of the heat exchange cover (1) is hinged to a frame (4), the other end of the heat exchange cover (1) is connected with a tension device and a heat exchange device is arranged in the heat exchange cover (1). According to the hot water heat exchanger for the cement kiln provided by the invention, two rows of spiral fin S-shaped tube panels can be adopted to increase the heat exchange area and improve the heat exchange efficiency; furthermore, the heat exchanger cover and the assembled heat exchange device are divided into a plurality of units and can operate separately or jointly, tube bundles are thermally exchanged due to the radiation of the cement kiln, hot air in the heat exchanger cover can be forcibly circulated by a fan, the heat convection can be improved on the basis of receiving the radiation heat exchange, and the heat exchange effect of a heat exchange tube bundle can be improved in the heat exchange cover; furthermore, if the heat exchange device needs to be changed or overhauled, and the fan sucks outdoor air and forcibly cool the kiln body, so as to prevent the over-high temperature of the kiln body and ensure the normal operation of the cement kiln.
Description
Technical field: the present invention relates to a kind of cement kiln hot water heat exchanger.
Background technology: revolving cement kiln is the device of a highly energy-consuming, need in the course of the work to dispel the heat as early as possible, ensure that kiln temperature can not higher than 350 DEG C, therefore need to dispel the heat as early as possible, existing revolving cement kiln skin is metal shell, inside establishes refractory masses, its surface radiating scarce capacity, cause kiln temperature higher, production when affecting.Existing heat abstractor, due to bulky, adopt hydraulic means, involves great expense, and is not suitable for site environment and delays to drop into practical application.The individual layer ligulate pipe of traditional mode, heat exchange area is little, causes kiln body to heat up, makes cement kiln cisco unity malfunction.
Summary of the invention: the object of this invention is to provide a kind of radiating efficiency high, shifts out the cement kiln hot water heat exchanger that is convenient, features simple structure that resets.Technical scheme of the present invention is: a kind of cement kiln hot water heat exchanger, it is outside that heat exchange cover (1) is enclosed in cement kiln body (2), with hot switching path (3) between heat exchange cover (1) and cement kiln body (2), heat exchange cover (1) one end is hinged in frame (4), heat exchange cover (1) other end connection tensioner, installs heat-exchanger rig in heat exchange cover (1).
The present invention adopts two row's helix fin S-shaped tube panels, heat exchange area is increased, heat exchange efficiency is higher, heat exchange cover and equipped heat-exchanger rig are divided into multiple unit, can separately or cooperation, and tube bank is not only subject to cement kiln radiation heat transfer, also utilize the hot-air forced circulation that blower fan makes in heat exchange cover, on the basis accepting radiation heat transfer, add heat convection, improve the heat transfer effect of heat-exchanging tube bundle in heat exchange cover.If heat-exchanger rig needs to change or maintenance, blower fan suction chamber outer air is carried out pressure cooling to kiln body, is prevented kiln temperature too high, ensures that cement kiln normally runs.
The present invention often organizes heat-exchanger rig can singly locate heat exchange quantity of heat given up, and also after two groups of parallel connections, then can export hot water after series connection, the resistance of this structure to current is little, prevents steam bubble from producing the vapour locking problem caused.For the boiler of small displacement, because resistance is less, be not easy to produce steam bubble, also can adopt after heat-exchanger rig is cascaded and finally export hot water.
Instant invention overcomes the very formidable problem of industry prior art, namely while finishing equipment function, reduce the volume of equipment, the complexity of minimizing equipment, owing to limiting by site condition, complex device is actual cannot in on-the-spot application on the spot, and therefore prior art cannot be implemented in fact.The present invention owing to adopting simple frame for movement, not temperature influence, not only simple but also effectively complete shifting out and resetting of heat exchange cover, reach the effect of getting twice the result with half the effort.The present invention can effectively lower kiln temperature, improves the thermal efficiency, extends the large-scale cycle of revolving cement kiln, increases the service life of revolving cement kiln.The present invention operationally, can as required, and shift out the heat exchange cover module that any one may break down separately, guarantee system is normally run, and in work, heat exchange cover remains static, and does not rotate with cement kiln.
