The utility model forms schmutzband easily to the inside pipe wall of present wastewater heat exchange device, and the problem that waste heat recovery is difficult proposes a kind of wastewater heat exchange device decontamination apparatus.
A kind of wastewater heat exchange device decontamination apparatus, on the dirt separator under the bypass line of the waste water inlet side of water end (W.E.) and the dirt separator bypass line of the waste water inlet side of water end (W.E.) be connected, and between connecting pipeline mounted valve; On the dirt separator under the bypass line of the following water side of water end (W.E.) and the dirt separator bypass line of the following water side of water end (W.E.) be connected, and between connecting pipeline mounted valve; On the dirt separator under the middle part bypass line of water end (W.E.) and the dirt separator middle part bypass line of water end (W.E.) be connected, and water hydro-thermal parallel operation WEX, the 3rd filter R are installed on connecting pipeline 3And valve.
The structure of water end (W.E.) is on the said dirt separator: the first filter R 1With the second filter R 2Between fill scrubbing ball CS, form scrubbing ball storage chamber V b, scrubbing ball storage chamber V bTwo ends are communicated with through annulus line, and valve is set.
Said water hydro-thermal parallel operation WEX is double pipe heat exchanger or shell and tube exchanger.
The said first filter R 1With the second filter R 2Mesh aperture less than 85% of scrubbing ball CS diameter.
The beneficial effect of the utility model: the wastewater heat exchange device decontamination apparatus of the utility model can pass through valve opening; The realization associated pipe is switched; Back and forth movement in the waste water tunnel that orders about under the promotion of waste water in the pipe of scrubbing ball at heat exchanger; The schmutzband of collision and friction tube inwall, thus remove the schmutzband on the inside pipe wall, reduce the heat exchanger dirtiness resistance to improve the heat exchange property of wastewater heat exchange device.This wastewater heat exchange device decontamination apparatus is that the waste water residual heat recovery is provided convenience, and improves the service life that waste water residual heat reclaims heat exchanger, for applying of waste water residual heat recovery provides technical support.

The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is further specified.
Embodiment 1
Shown in Fig. 1-3; A kind of wastewater heat exchange device decontamination apparatus of present embodiment is become by water end (W.E.), water water-to-water heat exchanger WEX, connecting line, valve and other enclosure group under water end (W.E.), the dirt separator on the dirt separator; Connecting line in the said device is divided into water pipeline, waste water pipeline; Wherein, the water water-to-water heat exchanger is double pipe heat exchanger or shell and tube exchanger.Water end (W.E.) is by the first filter R on the dirt separator 1, the second filter R 2, scrubbing ball CS, scrubbing ball storage chamber V b, connecting line, valve V 1, V 2And other enclosure group becomes; The scrubbing ball stores chamber V bThe straight length both sides of influent waste water side the first filter R is installed respectively 1, the second filter R 2, another one outlet C-C is connected with the waste water entrance point of wastewater heat exchange device; Water end (W.E.) is by the 3rd filter R under the dirt separator 3, connecting line, valve V3, V4, V5 and other enclosure group become.
The waste water inlet tube of water end (W.E.) is connected with waste water incoming flow pipeline on the dirt separator, and its C-C pipeline opening is connected with the water intake of water water-to-water heat exchanger WEX; The E-E pipeline opening of the following water end (W.E.) of dirt separator is connected with the discharge of wastewater mouth of water water-to-water heat exchanger WEX; On the dirt separator under the bypass line of the waste water inlet side B-B of water end (W.E.) and the dirt separator bypass line of the waste water inlet side D-D of water end (W.E.) be connected; On the dirt separator under the bypass pipe of the following water side A-A of water end (W.E.) and the dirt separator bypass pipe of the following water side F-F of water end (W.E.) be connected.
When wastewater heat exchange device decontamination apparatus carries out scrubbing, generally need to start several times repeatedly.Its working procedure is divided into: forward washes away program and backward erosion program.Forward washes away the stage, need open valve V 2, V 4, valve-off V 1, V 3, V 5, sanitary wastewater is through valve V 2, filter R 2, impact scrubbing ball CS and get in the heat exchanger tube of water water-to-water heat exchanger WEX, the scrubbing ball CS of disturbance is in the motion state of chaotic, through with collision, the friction of inside pipe wall dirt, dirt is sneaked in the waste water, through filter R 3, valve V 4The pipeline at place directly discharges, because the 3rd filter R 3Mesh less than the diameter of scrubbing ball CS, therefore be trapped in the 3rd filter R 3The place, and dirt emits with waste water, thus realize the function of the inside pipe wall dirt of removal water water-to-water heat exchanger; In the backward erosion stage, need open valve V 3, V 5, valve-off V 1, V 4, V 2, sanitary wastewater is through valve V 3, the 3rd filter R 3, the impact forward washes away and accumulates in the 3rd filter R 3Scrubbing ball CS, get in the heat exchanger tube of water water-to-water heat exchanger WEX, the scrubbing ball CS of disturbance is in the motion state of chaotic, through with collision, the friction of inside pipe wall dirt, dirt is sneaked in the waste water, flow through, the scrubbing ball stores chamber V b, the 3rd filter R 2, valve V 5Directly discharging is because the second filter R 2Mesh less than scrubbing ball CS diameter, therefore be trapped in filter R 2The scrubbing ball at place stores chamber V b, and dirt emits with waste water, thus realize the function of the inside pipe wall dirt of removal water water-to-water heat exchanger.
Regularly adopt forward to wash away program and backward erosion program repeatedly; Can remove the dirt on the heat exchanger tube inwall of wastewater heat exchange device; Each scrubbing operation is all operated to guarantee that scrubbing ball CS is back to the scrubbing ball and stores chamber V as last scrubbing with the backward erosion program bIn.
When water water-to-water heat exchanger WEX is in normal operating conditions, Open valve V 1, V 4, valve-off V 2, V 3, V 5, at this moment, sanitary wastewater is successively through valve V 1, filter R 1, get in the heat exchanger tube of water water-to-water heat exchanger WEX, and then through the 3rd filter R 3, valve V 4, be disposed to waste pipe.
