The present invention utilizes the heat exchange device of the second structure to perform on-line anti-fouling heat exchange method for sewage and surface water cooling and heat sources, including the following steps: a. Use a water source water pump to extract sewage or surface water from the water source, and the sewage or surface water is drawn from the water source water pipeline The source water entering the tube cluster of the online anti-fouling heat exchange device enters the layer, and the sewage or surface water flows in the source water into the layer and is pumped by the hot water pump and enters the tube cluster through the heat intake pipeline. The heat extraction medium flows in series in the heat exchange layer for heat exchange; b.

The water enters the brush bar in the layer and makes intermittent or continuous circular arc movements to clear it and discharge it through the sewage outlet of the online antifouling heat exchange device.

The present invention has the following beneficial effects: 1. The present invention adopts a heat exchange structure between the shell-and-tube type and the plate-type structure, which solves the problems of many shell-and-tube heat transfer tubes and complicated online anti-soft scale mechanical structure , At the same time, the advantage of high heat transfer efficiency of the plate heat exchanger is used to solve the problem that the immersion water intake heat exchanger and the rotating filter surface anti-blocking shell-and-tube heat exchanger cannot prevent soft dirt online. 2. A group of cylinders are used to set the tube clusters. The interlayers of the tube clusters are alternately set as the source water inlet layer and the heat extraction medium heat exchange layer from the outside to the inside. The sewage and surface water enter the source water inlet layer. Under the reciprocating cleaning action of the rod, the suspended matter in the source water entering the layer will not hang on the wall or stick, and the flow end will not be blocked, so it has a strong anti-blocking function. There is a first long gap and a second long gap at the lower end of the tube cluster, and a set of partitions is set in the first long gap, a set of baffles is set in the second long gap, and the heat medium is taken from the heat medium inlet. It enters the outermost heat extraction medium heat exchange layer, and then enters the heat extraction medium heat exchange layer of the second outer layer through the flow hole on the fourth blocking plate, and then takes the heat medium from the previous second outer layer The through holes on the first blocking plate corresponding to the heat medium heat exchange layer flow out into the heat extraction medium heat exchange layer of the next layer, and so on, the heat extraction medium flows in series in the heat extraction medium heat exchange layer, and finally The heat-taking medium flows out from the innermost heat-taking medium heat exchange layer through the first heat-taking medium output pipe and the heat-taking medium outlet. The heat exchange device with the above structure can increase the flow velocity in the layer and enhance the heat exchange effect. 3. Using two steel plates with the same shape and size to superimpose and curl the tube cluster, the source water entering layer and the heat-extracting medium heat exchange layer can respectively form spiral series channels, which can improve the flow rate and heat exchange efficiency in the layer at the same time , can also make the structure of the tube cluster simple and easy to process and manufacture. 3. The brush rod can be a rigid steel shaft or a flexible steel cable. The brush rod can be equipped with a brush or a flexible material. Driven by the swing rod, the brush rod makes intermittent or continuous circles when the source water in the tuft enters the layer. The arc movement can not only remove dirt and scale, but also disturb the water flow to enhance heat exchange. 4. Although the number of brush rods in each source water inlet layer is very small (only two brush rods are set), it ensures the online anti-softening and descaling of a large heat exchange area. This is the existing sewage and surface water cooling. It is not available in heat source heat exchange equipment, and the brush rod is easy to replace. 5. If a tube cluster with a diameter of 1m, a length of 3m, and a distance of 20mm is used, there will be a heat exchange area of 120m ² , but there are only 10 source water entry layers to be cleaned; if a shell-and-tube structure is used, at least More than 200 cleaning parts are needed, so the device can greatly improve the reliability of anti-blocking and descaling. 6. Due to the small number of brush rods, not only the auxiliary energy consumption is low, but also the investment cost of the online descaling heat exchange device can be greatly reduced. In addition, the volume of the heat exchange device of the present invention is also much smaller than that of the shell-and-tube type, thereby greatly reducing Small footprint. 7. The device of the present invention has the advantages of simple structure, easy installation, reliable operation, low manufacturing cost, and good effect of removing soft dirt. It is an ideal heat exchange for heat pump cold and heat sources used for building heating and air conditioning in the field of HVAC device. 8. The method of the present invention is easy to operate, reduces or avoids auxiliary process operations and resource consumption, and can fundamentally solve the problem of water intake and heat exchange of such unclean water.
