Abstract
The utility model belongs to chemical industry application apparatus field, concretely relates to high -efficient heat pipes formula air heat exchanger. A high -efficient heat pipes formula air heat exchanger, includes the box, the closing plate still includes heat pipe and annular distortion piece, box middle part set up the closing plate that has a plurality of through -holes, the closing plate divide into flue gas passageway and air duct with the box, the inside heat pipe that sets up of box, the heat pipe be reducing formula venturi, heat pipe outer wall whole body equidistance welding a plurality of annular distortion piece, the path of heat pipe department pass the closing plate through the diaphragm orifice.
Description
Technical field
The utility model belongs to Application in Chemical Engineering apparatus field, is specifically related to a kind of High Efficiency Thermal tubular type air heat exchanger.
Background technology
Air preheater is energy-saving equipment important in Chemical Manufacture, comparatively conventional is heat pipe preheater, and heat pipe preheater is easy for installation, reliable, volume is little, take up an area few, but due to sulfur-bearing in flue gas and various impurity, be deposited on air preheater surfaces, have impact on heat transfer effect greatly, serious corrosion is caused on opposite heat tube surface simultaneously, preheater was lost efficacy, have impact on production efficiency greatly.
Summary of the invention
For Problems Existing, the utility model proposes a kind of High Efficiency Thermal tubular type air heat exchanger.
A kind of High Efficiency Thermal tubular type air heat exchanger, comprises casing, sealing plate, also comprises heat pipe and annular twisted sheet; The sealing plate of some through holes is provided with in the middle part of described casing, casing is divided into exhaust gases passes and air duct by described sealing plate, described box house arranges heat pipe, described heat pipe is reducing type Venturi tube, several annular twisted sheets of the equidistant welding in the described heat pipe outer wall whole body, the most path place of described heat pipe by plate hole through sealing plate.
Described air duct comprises air intake and air outlet slit, and exhaust gases passes comprises smoke inlet and exhanst gas outlet.
Described heat pipe, two diameter is comparatively large, and to centre, gradual change attenuates gradually, mid diameter is minimum, forms a Venturi tube structure, and in pipe, medium moves upward from heat pipe bottom by thermal evaporation, according to Venturi effect, steam moves to heat pipe top with larger speed, improves heat transfer efficiency.
Described heat pipe is in a row staggered, forms oval gap between pipe row, and flue gas, when superheater tube, strengthens flue gas and air flowing, makes tube surface not easily dust stratification, improve heat transfer efficiency.
Described annular twisted sheet is wave line style, increases heating surface area, in flow of flue gas process, forms larger turbulent flow, improve heat transfer efficiency.
Described sealing plate, separates air and flue gas, completes the reverse flow of two kinds of fluids, prevents two kinds of fluid chemical field infiltrations.
In said apparatus, reducing type Venturi tube is directly connected with annular twisted sheet, and during flue gas circulation, in heat pipe, medium is directly by thermal evaporation, upwards flows, enters Venturi tube the first half, after rising, heat is passed to air duct, flow down again after medium condenses.
The beneficial effects of the utility model are: structure is simple, easy for installation, alleviate tube surface corrosion and deposition, have delayed heat pipe preheater service life, to improve heat transfer efficiency greatly, solve the problem of flue gas corrosion and deposition heat pipe simultaneously.

Fig. 1 is Facad structure schematic diagram of the present utility model;
Fig. 2 is overlooking surface structural representation of the present utility model;
Fig. 3 is construction profile of the present utility model;
Fig. 4 is heat pipe structure schematic diagram of the present utility model;
In figure, 1 is heat pipe, and 2 is annular twisted sheet, and 3 is sealing plate, and 4 is casing, and 41 is air outlet slit, and 42 is smoke inlet, and 43 is exhanst gas outlet, and 44 is air intake.
Detailed description of the invention
A kind of High Efficiency Thermal tubular type air heat exchanger, comprise casing 4, sealing plate 3, is characterized in that: also comprise heat pipe 1 and annular twisted sheet 2; The sealing plate 3 of some through holes is provided with in the middle part of described casing 4, casing 4 is divided into exhaust gases passes and air duct by described sealing plate 3, described casing 4 inside arranges heat pipe 1, described heat pipe 1 is reducing type Venturi tube, several annular twisted sheets 2 of the equidistant welding in the described heat pipe 1 outer wall whole body, the most path place of described heat pipe 1 by plate hole through sealing plate 3; Described annular twisted sheet 2 is wave line style; Described air duct comprises air intake 44 and air outlet slit 41, and exhaust gases passes comprises smoke inlet 42 and exhanst gas outlet 43.
During device work, flue gas inputs from smoke inlet 42, the oval gap that pipe row is formed, and strengthen flue gas and air flowing, in heat pipe 1, medium (for water) is because of the high-temperature heating explosive evaporation of flue gas, moves to air side, and this is heat pipe 1 heating section; Air inputs from air intake 44, and temperature is low, and the water cooling of evaporation, water becomes water after cooling, and flow down along inwall again, this is heat pipe 1 heat extraction section; Iterative cycles flowing in heat pipe 1.
