Description

Vertical heat exchanger

Technical field

The utility model relates to heat exchanger, particularly a kind of vertical heat exchanger that uses rivers water/sewage as cooling medium.

Background technology

Along with the appearance of a series of energy saving policies of country, energy-conservation and tap a new source of energy extremely urgently, utilized rivers water, sewage as Cooling and Heat Source both at home and abroad, the developing water source heat pump technology.But existing heat exchanger pattern is relatively strict to water quality requirement, if consider to filter before rivers water or sewage enter heat exchanger, precipitate, technical process such as biological treatment, exists water temperature to raise, and first cost and water treatment expense are crossed problems such as height.In existing employing rivers water or the heat transmission equipment of sewage as cooling water, water treatment procedure all adopts the mode of not exclusively handling mostly, but all has problems such as stopping up serious, cleaning, mediation inconvenience.As by the patent of invention specification of notification number CN1274603C disclosed " utilize the method for fetching water of municipal sewage Lowlevel thermal energy and automatically decontamination apparatus " with by the application for a patent for invention specification of notification number CN1995890A disclosed " a kind of solid-liquid separating method of fluid-bed heat exchanger " etc., this shows existing solution mostly all from exploitation clean, mediation equipment and technological angle consider.Because the structure problem of existing shell and tube exchanger, clean and mediation inconvenient, still exist the rivers water turbidity in the actual mechanical process when too high, the frequency that obstruction occurs is too high, maintenance is frequent, and maintenance cost is crossed problems such as height, does not fundamentally solve the precipitation blocking problem.

The utility model content

Technical problem to be solved in the utility model provides a kind of vertical heat exchanger, has good precipitation process, anti-clogging performance, can use rivers water/sewage as cooling medium.

The technical scheme that its technical problem that solves the utility model adopts is: vertical heat exchanger of the present utility model, comprise housing and heat exchanger tube, the housing inner chamber is by upper perforated plate, lower perforated plate is separated to form epicoele, lumen and cavity of resorption, the two ends of heat exchanger tube respectively with upper perforated plate, lower perforated plate connects and with epicoele, cavity of resorption is communicated with, epicoele, cavity of resorption respectively with the medium inlet pipe that is cooled, the medium that is cooled goes out pipe and communicates, lumen then advances with cooling medium, cooling medium goes out pipe and communicates, it is characterized in that: described cooling medium inlet pipe, cooling medium goes out the top that pipe is positioned at lumen, the tangential setting of cavity wall in the cooling medium inlet pipe edge.

In technique scheme, described lower perforated plate is concave cone shpae down, is provided with the blow-off pipe that leads to outside the housing at its awl end.

The beneficial effects of the utility model are, have good precipitation process, anti-clogging performance, having solved the traditional shell pipe heat exchanger is prone to obstruction, precipitation alluvial and cleaning inconvenience, needs complicated problems such as water treatment procedure, can obviously reduce initial cost and operating cost, the liquid that is suitable for containing more than the solid impurity with rivers water and sewage etc. is the heat pump heat exchanger of cooling medium.

Description of drawings

This specification comprises following two width of cloth accompanying drawings:

Fig. 1 is the profilograph of the utility model vertical heat exchanger;

Fig. 2 is the cutaway view along A-A line among Fig. 1.

Parts shown in the figure, toponym and pairing mark: housing 10, upper perforated plate 11, lower perforated plate 12, epicoele 13, lumen 14, cavity of resorption 15, heat exchanger tube 20, the medium inlet pipe 21 that is cooled, the medium that is cooled go out pipe 22, cooling medium inlet pipe 23, blow-off pipe 24, cooling medium and go out pipe 25.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

With reference to Fig. 1, vertical heat exchanger of the present utility model comprises housing 10 and heat exchanger tube 20, housing 10 inner chambers are separated to form epicoele 13, lumen 14 and cavity of resorption 15 by upper perforated plate 11, lower perforated plate 12, the two ends of heat exchanger tube 20 are connected with upper perforated plate 11, lower perforated plate 12 respectively and epicoele 13, cavity of resorption 15 are communicated with, epicoele 13, cavity of resorption 15 go out pipe 22 with the medium inlet pipe 21 that is cooled, the medium that is cooled respectively and communicate, and 14 of lumens go out pipe 25 with cooling medium inlet pipe 23, cooling medium and communicate.See figures.1.and.2, described cooling medium inlet pipe 23, cooling medium go out the top that pipe 25 is positioned at lumen 14, and cooling medium inlet pipe 23 is along the tangential setting of lumen 14 inwalls.Cooling medium has been shown among Fig. 1 to manage 25 a kind of preferred laying mode, promptly described cooling medium goes out the axis extension of pipe 25 along housing 10, enters lumen 14 by passing epicoele 13 outside the housing 10.For more effectively removing the contained solid impurity of cooling medium, with reference to Fig. 1, described lower perforated plate 12 is concave cone shpae down, is provided with the blow-off pipe 24 that leads to outside the housing 10 at its vertex of a cone.

After the rivers water/sewage that contains silt enters lumen 14 from cooling medium inlet pipe 23, because tangential screw and centrifugal action, cooling medium is earlier along lumen 14 side screw current downflow, and arrived lumen 14 bottoms by the bottom to inside spin, and then the spiral that makes progress, go out pipe 25 by cooling medium at last and flow out.Because the density of silt is greater than the density of water, silt can be to the inwall side flow with respect to water, the silt of close inwall is because the effect of gravity effect and spiral flow field is mobile to the bottom of lumen 14, be deposited on the vertex of a cone place of lower perforated plate 12, realized separating of silt and water, can be continuously or regularly discharge silt by blow-off pipe 24.The medium that is cooled enters epicoele 13 through the medium inlet pipe 21 that is cooled, and flows downward via heat exchanger tube 20, by flowing to cavity of resorption 15 after tube wall and the cooling medium heat exchange, after the medium that is cooled goes out pipe 22 outflow heat exchangers.

Some principles of the above the utility model vertical heat exchanger that just explains through diagrams, be not be the utility model to be confined to shown in and in described concrete structure and the scope of application, so every the corresponding modify and equivalent that might be utilized all belongs to the claim that the utility model is applied for.
