Abstract
The utility model discloses a heat-exchanging and energy-saving device for boiler smoke. The heat-exchanging and energy-saving device comprises a cylinder heat exchanger shell body and a plurality of vertically arranged heat exchange pipes for flue gas, wherein the heat exchange pipes are contained in the heat exchanger shell body. Circulating water areas are formed in gaps between the heat exchange pipes and the heat exchanger shell body. The bottom end of each heat exchange pipe is provided with a smoke inlet through which the smoke passes from bottom to top, and the top end of each heat exchange pipe is provided with a smoke exhaust port. The top of the side wall of the heat exchanger shell body is provided with a water inlet through which circulating water passes from top to bottom, and the bottom of the side wall of the heat exchanger shell body is provided with a water outlet. The heat exchanger shell body is divided into a plurality of airtight cavities through separating plates from top to bottom, and every two adjacent cavities are communicated through a plurality of communicating pipes. Through improvements of the inside of the heat-exchanging and energy-saving device, the heat-exchanging and energy-saving device is divided into a plurality of layers, the circulating water is enabled to sufficiently exchange heat with the flue gas, a large difference between temperatures of the circulating water and the flue gas is always maintained, and therefore heat exchange efficiency is improved.
Description
Technical field
The utility model relates to a kind of energy saver, is specially a kind of flue gas heat exchange energy saver for boiler, belongs to the energy-conserving and environment-protective technical field.
Background technology
With a large amount of heats, if directly discharging is a kind of no small energy loss, what generally use at present is that mode by the shell and tube heat exchange keeps the heat in the flue gas as far as possible and stores in the flue gas of boiler.Two kinds of laying method: Transverse formulas/vertical are arranged usually; Because the boiler smoke trend is to discharge from lower to upper or parallel up discharging, from physics heat exchange principle, the two temperature difference Yue Da Change thermal efficiency is higher.
Maximum smoke temperature is at heat exchange energy saver inlet port end, and along with flue gas rises, Tong Guo Change thermal center can absorb heat by device, flue-gas temperature reduces gradually, arrive the heat exchange energy saver port of export, be the flue-gas temperature minimum point, formed these characteristics of heat exchange energy saver for this reason.Because these two kinds of laying methods all can't overcome this physical phenomenon.
Take away the water of heat medium, by bottom in and top out, formed thus the water temperature cold lower part and hot upper part, flue gas is equally by bottom in and top out, this phenomenon has caused the two temperature difference in heat exchange energy saver, more up the less transmission capacity that makes of the temperature difference successively decreases, the inefficiency of energy saver, and this phenomenon is not that formula is touched in best heat extraction heat absorption for this reason.
The utility model content
The purpose of this utility model is for a kind of boiler smoke heat exchange energy saver is provided, to solve the problems referred to above of prior art.
The purpose of this utility model can be achieved through the following technical solutions.
A kind of boiler smoke heat exchange energy saver, comprise: the cylinder heat exchanger shell, the flue gas heat exchanger tube of some vertical arrangements of accommodating in the heat exchanger shell, space between heat exchanger tube and the heat exchanger shell is the circulation pool, described heat exchanger tube bottom is the air inlet that flue gas from bottom to top passes through, and the top is exhaust outlet; The heat exchanger shell top side wall is the water inlet that recirculated water from top to bottom passes through, and heat exchanger shell sidewall bottom is delivery port; Described heat exchanger shell becomes the airtight cavity in some rank by baffle for separating from top to bottom, is communicated with by some communicating pipes between two adjacent cavitys.
The top near upper single order cavity suitable for reading of described communicating pipe, the end opening of communicating pipe is near the bottom of lower single order cavity.
Described water inlet is arranged at the cavity side of going up single order most, and delivery port is arranged at the cavity side of descending single order most.
The height of described every single order cavity is identical.
As another kind of form of the present utility model, the horizontal mode of heat exchange energy saver is equivalent structure of the present utility model, also should be in protection domain of the present utility model.
The boiler smoke heat exchange energy saver that designs by the utility model, by the transformation of heat exchanging energy saver inside, heat exchange energy saving equipment is separated into some layers, make the abundant heat exchange of recirculated water and flue gas, and it is larger poor that the two temperature remains, improved heat exchange efficiency.
