Abstract

The invention discloses a heat exchanger. Two ends of a heat exchanging capillary tube plate are respectively connected with a collection box, cross-shaped partition plates are arranged in an upper collection box and a lower collection box, a heat exchanging capillary tube is divided into four portions, the upper collection box is connected with a water inlet and a water outlet, and cooling water passes through four return strokes through the collection box in the heat exchanger to sequentially flow past four portions of the capillary tube. According to the collection box type four-return-stroke heat exchanger, the cooling water passes through four return strokes to enable heat exchanging to be uniform, and heat exchanging coefficient can be effectively improved. With the structure, the heat exchanger is convenient to manufacture, low in construction price, flexible in series and parallel connection use, and capable of being used for a waste heat recycling occasion of corrosive fume and the like.

Description

A kind of heat exchanger
Technical field
The present invention relates to a kind of waste heat recovering energy conserving device, particularly a kind of heat exchanger.
Background technology
In large-scale power station, for economize energy is provided with heat recovery heat exchanger.Heat recovery heat exchanger is arranged on entrance or the exit of desulfurizing tower usually.Desulfurizing tower outlet or exhaust pass place flue gas contain so 2deng corrosive gas, when flue-gas temperature is lower than corrosive gas acid dew point, corrosive gas can produce condensation, etching apparatus.
Existing flue gas heat-exchange unit heat exchanger tube many employings noncorroding metal or fluoroplastics material manufacture, and form structure mostly is U-shaped design, and manufacturing cost is high, complex process.
Summary of the invention
The object of the present invention is to provide a kind of while increase effective heat exchange area heat exchange more even, and the heat exchanger of etching problem in waste heat recovery process can be solved.
For achieving the above object, the technical solution used in the present invention is: comprise heat exchanger shell and be arranged on the heat exchange capillary in heat exchanger shell, described heat exchanger shell upper, lower end is separately installed with the upper collecting chamber and lower header that are connected with heat exchange capillary, upper collecting chamber offers water inlet and delivery port, described is upper, lower header all by cross partition by upper, lower header and with upper, the heat exchange capillary that lower header is connected is divided into four parts and A, B, C, D district, wherein the A district of upper collecting chamber is connected with water inlet, the D district of upper collecting chamber is connected with delivery port, and A, B, C, D district is communicated with successively.
The B district of described upper collecting chamber offers with on the dividing plate in C district the through hole being communicated with B district and C district, the dividing plate in the A district of lower header and B district, C district and D district offers the through hole in A district and B district and C district and D district.
Described heat exchange capillary diameter be 6 ?12mm.
Described heat exchanger adopts PP and PTFE material manufacture.
Heat exchange capillary two ends of the present invention connect header respectively, and install cross partition in upper and lower header, heat exchange capillary is divided into four parts, and upper collecting chamber is connected with into water and delivery port.This cluster case type four backhaul heat exchanger, increases heat exchange area in certain space, and cooling water experiences four backhauls makes heat exchange even, effectively improves the coefficient of heat transfer.And easily manufactured, cost is low, and series and parallel uses flexibly, can be used for the waste heat recovery occasion of corrosive fume etc.Significant for energy saving for power plants consumption reduction.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail.
See Fig. 1, 2, the present invention includes heat exchanger shell 2 and the diameter be arranged in heat exchanger shell 2 be 6 ?the heat exchange capillary 4 of 12mm, described heat exchanger shell 2 upper, lower end is separately installed with the upper collecting chamber 1 and lower header 3 that are connected with heat exchange capillary 4, upper collecting chamber 1 offers water inlet 5 and delivery port 6, described is upper, lower header 1, 3 all by cross partition 7 by upper, lower header 1, 3 and with upper, lower header 1, the 3 heat exchange capillaries 4 be connected are divided into four parts and A, B, C, D district, wherein the A district of upper collecting chamber 1 is connected with water inlet 5, the D district of upper collecting chamber 1 is connected with delivery port 6, and A, B, C, D district is communicated with successively, namely the B district of upper collecting chamber 1 and the dividing plate in C district offer the through hole being communicated with B district and C district, the A district of lower header 3 and B district, the dividing plate in C district and D district offers the through hole in A district and B district and C district and D district.
Heat exchanger of the present invention adopts PP and PTFE material manufacture.
Its course of work is as follows: flue gas enters from heat exchanger shell 2 side, flows through heat exchanger shell 2 and the cooling medium heat exchange in heat exchange capillary 4, flows out from heat exchanger shell 2 opposite side.Cooling medium enters from cooling water intake 5, heat exchange capillary is flowed through by the A district of upper collecting chamber 1, arrive the A district of lower header 3, the B district of lower header 3 is arrived by the hole on cross partition 7, the B district of upper collecting chamber 1 is upwards arrived through heat exchange capillary 4, the C district of upper collecting chamber 1 is arrived by the hole on cross partition 7, the C district of lower header 3 is arrived downwards through heat exchange capillary 4, the D district of lower header 3 is arrived by the hole on cross partition 7, upwards arrive the D district of upper collecting chamber 1 through heat exchange capillary, discharge from delivery port 6.
Cooling water by header, experiences four backhauls and flows through A, B, C, D tetra-semi-capillary successively in heat exchanger.Cooling water and flue gas pass through capillary heat exchange, Mist heat recovering.
The invention has the advantages that:
PP and PTFE has good chemical stability and resistance to chemical attack ability, as resistance to strong acid, highly basic, strong oxidizer etc., has heat-resisting, cold-resistant and wear resistance, Long-Time Service temperature range Wei ?200 ~+250 DEG C; In addition, also possess electrical insulating property, there is the features such as not being stained with, does not absorb water.Adopt PP and PTFE to make heat exchanger, flue gas low-temperature corrosion and heat exchanger tube scale problems can be solved preferably.
Heat exchanger adopts shell-and-tube design, and shell adopts integrally moulded manufacture.Heat exchange capillary plate two ends connect header respectively, and install cross partition in upper and lower header, heat exchange capillary is divided into four parts, and upper collecting chamber is connected with into water and delivery port.This cluster case type four backhaul heat exchanger, can increase heat exchange area in certain space, and cooling water experiences four backhauls makes heat exchange even, effectively improves the coefficient of heat transfer.This kind of structure heat exchanger is easily manufactured, and cost is low, and series and parallel uses flexibly, can be used for the waste heat recovery occasion of corrosive fume etc.Significant for energy saving for power plants consumption reduction.
