Abstract

The utility model relates to a heat exchanger used for recycling the heat contained in industrial wastewater and souring-bath wastewater. The heat exchanger comprises an outer sleeve and a core pipe, wherein the outer sleeve is provided with a wastewater inlet/outlet pipe connector, an upper end plate, a lower end plate and an end plate gland; the core pipe penetrates through the outer sleeve, and the two ends of the core pipe extend out of the end plate and the gland to be connected into a running water pipe; the pipe wall of the core pipe takes the corrugated structure along the axial direction; a straight-pipe or helix-pipe clear water turbulator with two ends closed is arranged in the core pipe; and a ring-shaped multilayer wastewater turbulent-fluid sleeve with a through hole is arranged between the outer sleeve and the core pipe. The corrugated structure of the heat exchanger enlarges the contact area when the cold medium and the heating medium flow; the clear water turbulator and the wastewater turbulator arranged in the utility model can convert the flowing directions of the cold medium and the heating medium multiply times, and the heat exchanging time is prolonged, thereby improving the heat exchanging efficiency of the heat exchanger.

Description

A kind of heat exchanger

Technical field

The utility model relates to hot swapping, particularly relates to a kind of heat exchanger that industrial wastewater, bath wastewater institute heat content are reclaimed.

Background technology

Multiple structures such as that existing heat exchanger has is board-like, cluster type, finned, bushing type.Wherein, mostly the primary structure form of tube-in-tube heat exchanger generally is to be made up of outer tube and the core pipe that is positioned at wherein.The outer tube two ends are provided with shrouding and constitute a closed cavity, the cavity two ends be provided with the spent hot water into and out of water pipe head; The core pipe that connects running water is in closed cavity.This tube-in-tube heat exchanger has certain heat exchange effect, but because its core pipe is usually designed to metal straight pipe, and does not have turbulent device, thereby when doing heat exchange, the refrigerant heating surface area in causing flowing is less, and heat exchanger effectiveness is lower.

Summary of the invention

The utility model provides a kind of heat exchanger, purpose is by changing the version of core pipe, promptly at core pipe inside, outer setting turbulator, thereby make hot and cold matchmaker's fluid in heat exchanger, do flowing of changeableization orientation, increase the mobile contact of refrigerant heating surface area with the lengthening flow process, and then improve heat exchange efficiency.

Technical solution of the present utility model:

The heat exchanger that the utility model is alleged mainly comprises outer tube and core pipe, and outer tube is provided with waste water water inlet pipe and water outlet pipe joint, end plate and end plate gland up and down; Core Guan Yiyu outer tube be same center line among outer tube, its two ends is stretched out outside end plate and the gland, is connected among the running water pipe.The tube wall of described core pipe is wave structure vertically; Be provided with the clear water turbulator in the core pipe; Be provided with waste water turbulent flow chuck between outer tube and the core pipe.

Further technical solution of the present utility model:

(1) crest of core tube wall wave structure and trough homomorphosis, the number of its crest (or trough) are 4-12.

(2) straight tube that set clear water turbulator is a closed at both ends in the core pipe or be helix tube or be the band of flat body.

(3) the waste water turbulent flow chuck that is provided with between outer tube and the core pipe is ringwise polylayer forest combination, and each layer body is axially arranged with a plurality of through holes that differ in size along it.

(4) the waste water water inlet pipe and water outlet pipe joint branch that is provided with of outer tube is located at the different side direction of core pipe.

(5) two ends of core pipe are provided with among reducer union connection and the water supply pipe

The beneficial effects of the utility model:

(1) the utility model metal straight pipe that will have the core, heat exchanger pipe now is designed to axially be wave structure, has increased hot and cold matchmaker contact area when flowing, and has improved the heat exchange efficiency of heat exchanger;

(2) the utility model is respectively equipped with clear water and waste water turbulent flow device between core pipe inside and outer tube and core pipe, and repeatedly the cold and hot matchmaker's flow direction of conversion has prolonged heat-exchange time, has improved the heat exchange efficiency of heat exchanger;

(3) the waste water water inlet pipe and water outlet pipe joint branch that is provided with of the utility model outer tube is located at the upper and lower side of non-the same side of core pipe, and it is more balanced to be of value to the heat that the spent hot water dispersed in the cavity of sealing, more helps heat exchange.

(4) outer tube of the utility model heat exchange cavity adopts end plate and the sealing of end plate gland up and down; The core pipe adopts reducer union to be connected with water supply pipe, so the regular cleaning of turbulent device and install and remove very convenient.
