Description
Technical field:
The utility model relates to the box heat exchanger of a kind of sewage, belongs to technical field of heat exchangers.
Background technology:
At present, be used for the water-water heat exchanger of source of sewage, be called flow passage type heat transfer device, overflow-type heat exchanger etc., because its shape all is a cuboid, resemble a chest, so can be referred to as box heat exchanger, the structure and the principle of existing box heat exchanger are as shown in Figure 1.
The runner of such heat exchanger two media is independent and adjacent, utilizes the laminate 2 between the medium to carry out heat exchange, and there are 4 deficiencies in existing structure: first point, the following current position is arranged, and not exclusively be countercurrent flow, heat transfer efficiency is low during following current.Second point, flow velocity is slow, and the width of flow path minimum of this heat exchanger is 0.7 meter; This is not because the dirt in the sewage needs 0.7 meter width to pass through; But, reliable stable installation property being arranged for making casing 1 because the height of heat exchanger has surpassed 2 meters, width of flow path needs 0.7 meter at least.Under the certain situation of flow, V (flow velocity)=Q (flow)/F (circulation area), wide runner increase circulation area, and flow velocity reduces, and has not only reduced heat transfer coefficient, has also increased the deposition of dirt.If improve flow velocity V through enlargement discharge Q, that will increase energy consumption, raises the cost; Thirdly, rectangular flange 3 areas at casing 1 two ends are big, and processing charges is high, and it is unreliable to seal.The flange size of this heat exchanger tank ends is about height * width=2100mm*700mm; Carry out flat seal with about 60 bolts, 4 linkage rectangle flanges 3 with blind flange 5; The sealing surface of flange 3 and blind flange 5 all has only through machining, makes sealing plane have corresponding flatness, the ability positiver sealing; And square flange will carry out plane processing, the processing cost that this just need be very high again after welding with casing 1.If sealing surface is not processed,, after welding, produced distortion again because the surface of steel plate is a black skin; More than 60 Bolt Connection, the pretightning force of bolt 4 is difficult to grasp suitablely, and these factors can cause sealing unreliable; Even fluid pressure has only 0.2MPa, also very easily leak; The 4th point, assembling and dismounting difficulty, labour intensity is big, is not easy to the cleaning of runner.Because flange 3 appearance and sizes are big, design thickness is also with regard to corresponding increase, and the weight of blind flange 5 is more than half ton, and bolt 4 quantity are many again, so increased the difficulty and the labour intensity of assembling.Carry out the inside cleaning if disassemble, increased erection stress again, even install blind flange, can not seal again, therefore this structure can not be carried out the runner cleaning.
The utility model content:
The purpose of the utility model is to overcome the deficiency of above-mentioned prior art and provides a kind of heat-transfer effect good, and cost is low, not only assembles and dismantles simply, and labour intensity is low, and convenience for washing, the box heat exchanger of the reliable sewage of sealing property.
The purpose of the utility model can reach through following measure: the box heat exchanger of a kind of sewage, and it comprises casing, the two ends of casing are provided with end plate; It is characterized in that level is evenly distributed with laminate in the described casing; Form runner between laminate and the laminate, runner is respectively clear water runner and sewage runner, and is independent and adjacent between clear water runner and the sewage runner; The fresh water pipeline elbow assembly that passes through two ends between the clear water runner respectively connects; One end of ground floor clear water runner is established the clear water import, and an end of last one deck clear water runner is established clear water output, and the sewage conduct elbow assembly that passes through two ends between the adjacent sewage runner respectively connects; One end of ground floor sewage runner is established outlet of sewer, and an end in last one deck effluent stream road is established the sewage import.
In order further to realize the purpose of the utility model; Described every laminar flow all vertically is provided with two rectangle deflection plates in the road; The length of two rectangle deflection plates is less than the length of laminate; The upper and lower side of rectangle deflection plate links to each other with laminate, and an end of one of them deflection plate links to each other with a side of casing, and an end of another deflection plate links to each other with the opposite side of casing.
In order further to realize the purpose of the utility model, the length of described two rectangle deflection plates is less than the length 100～300mm of laminate.
In order further to realize the purpose of the utility model, the side casing of described every layer of sewage runner is provided with openable subsequent use observation clean-up port.
The utility model is compared with prior art can produce following good effect: one, and sewage and clear water flow up and down at laminate in the opposite direction, and two media is in the countercurrent flow state, and the minimum temperature of the minimum temperature of sewage and clear water is met the heat transfer efficiency height.Two, every laminar flow road all adopts the baffling technology, after the employing baffling technology; The width of runner also is enough to not stop up through dirt, has increased the distance that flows, and under the certain situation of flow, has suitably improved flow velocity; Also reduce the deposition of dirt, thereby improved heat transfer coefficient.And fluid all produces disturbance in each corner, and these factors all help to conduct heat.Three; The end plate of casing is welded on the casing, does not need machining, is welded on the end plate with the steel pressure-bearing pipe fitting of national standard; And be connected into the pipeline that needs; Conduit seals with national standard seals, and bearing capacity improves greatly, can design and select for use pipe fitting and the seal under the different pressures condition according to customer requirements.Four, assemble and dismantle, clean all very convenient.One group of pipe fitting weight has only 10 kilograms, pulls down pipe fitting and just can clean inner flow passage easily, has cleaned again and has loaded onto; Not only labour intensity is low; And convenience for washing, sealing property is reliable, and subsequent use observation clean-up port is used to observe and clear up the mid portion of sewage runner.
