A kind of novel metalloid heat exchanger
Technical field
The utility model relates to sewage source heat pump heat exchanger, particularly relates to a kind of novel metalloid heat exchanger.
Background technology
At present, energy-conserving and environment-protective project is just extensively promoted in all trades and professions, in reality, the extraction of cold and hot amount and recovery are widely used, and this needs a large amount of heat exchanger apparatus, extract at present the heat-exchanger rig that reclaims cold and hot amount all take metallic recuperator as main, but there is corrosivity in some heat transferring medium or Cooling and Heat Source, or dirty stifled etc., as various sewage, industrial wastewater, seawater etc., the heat-exchanger rig of these occasions, when thering is certain exchange capability of heat, must have anti-blocking, anticorrosive and anti-microbe ability, and metallic recuperator is anticorrosive and the ability of microorganism is poor, and because its anti-dirty stifled and antifreeze ability of volume and structural limitations is also poor, and the intensity of part nonmetallic heat exchanger is lower, bearing capacity is poor, exchange capability of heat is undesirable, also be difficult to the heat transfer effect that long term maintenance is good.
Utility model content
The technical problems to be solved in the utility model is, provides one to have heat exchange efficiency high, and bearing capacity is strong, anti-blocking, antifreeze, anticorrosive, antimicrobial, again novel metalloid heat exchanger easy to assembly.
The technical scheme adopting is:
A kind of novel metalloid heat exchanger, comprises return connector, distributive pipe and collection pipe that nonmetallic heat exchange plate, high strength nonmetallic materials are made.Described heat exchanger plates is several heat exchanger plates with round tubular runner, by multiple heat exchanger plates, pass through two ends return connector plate package in series as required, the return connector at the upper and lower two ends of each plate package connects respectively collection pipe and distributive pipe, by collection pipe and distributive pipe, make plate package in parallel successively, form a kind of novel metalloid heat exchanger.
The utility model has the advantages that:
1,, owing to adopting nonmetallic materials to add trace element, guaranteeing, on the basis of thermal conductivity factor, to have and do not corrode, the characteristic such as antimicrobial;
2, medium runner is circular, and intensity is good, and pressure-bearing is high;
3, external heat-exchanging face is circular,, with tabular heat exchanger plates ratio, has increased heat exchange area, and has increased perturbation, thereby increased exchange capability of heat;
4, between tubulose runner, there is banded muscle, can prevent that foul is wound around, simultaneously muscle place ease of assembly and fixing;
5, after assembling, external channel is wide, does not stop up, easily cleaning.

The specific embodiment
A kind of novel metalloid heat exchanger, comprises that being added with nano material increases the nonmetallic heat exchange plate 1 of heat exchange, return connector 3, distributive pipe 4 and the collection pipe 5 that high strength nonmetallic materials are made.Described heat exchanger plates 1 is several heat exchanger plates (see figure 2)s with round tubular runner, by multiple heat exchanger plates, pass through two ends return connector 3 plate package 2 in series as required, the return connector 3 at each plate package two ends Shang Xia 2 connects respectively collection pipe 5 and distributive pipe 4, by collection pipe 5 and distributive pipe 4, make plate package 2 in parallel successively, form a kind of novel metalloid heat exchanger.
The course of work is described:
This heat exchanger is mainly used in draws heat in sewage, generally be applied to as sewage source heat pump system etc., as example: this heat exchanger is arranged in mobile cesspool, refrigerating medium in heat pump is by distributive pipe " 4 ", enter sewage heat change plate, return connector " 3 " through each heat exchanger plates " 1 " two ends carries out water conservancy diversion, from heat exchanger plates " 1 " inner flow passage, flow through from the bottom to top, by heat exchanger plates " 1 " and outside sewage, carry out heat exchange, finally by collection pipe " 5 " outflow heat exchanger simultaneously.
Refrigerating medium after draw heat is warmed from sewage, enters source pump with the heat of drawing from sewage, and its heat is extracted by unit, and temperature is lowered again, then reenters sewage heat exchanger and absorb heat, and moves in circles.Because this heat exchanger belongs to immersion type, between heat exchanger plates, spacing is wide, and sewage slowly flows in outside, and the phenomenon such as can not result in blockage.
