Description
Technical field:
The present invention relates to the box heat exchanger of a kind of sewage, belong to technical field of heat exchangers.
Background technology:
At present, be used for the water-water heat exchanger of source of sewage, be referred to as 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 of existing box heat exchanger and principle 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 installation stability 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 by 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 and blind flange 5, the sealing surface of flange 3 and blind flange 5 all has only through machining, make 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 blind flange is installed, can not seal again, therefore this structure can not be carried out the runner cleaning.
Summary of the invention:
The objective of the invention is to overcome the deficiency of above-mentioned prior art and provide a kind of heat-transfer effect good, cost is low, not only assembles and dismantle simple, and labour intensity is low, and clean convenient, the box heat exchanger of the reliable sewage of sealing property.
Purpose of the present invention can reach by following measure:
The present invention can produce following good effect compared with the prior art: one, and sewage and clear water flow up and down in the opposite direction at laminate, 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 by dirt, has increased the distance that flows, and has suitably improved flow velocity under the certain situation of flow, 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, do not need machining, steel pressure-bearing pipe fitting with national standard is welded on the end plate, 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 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 clean conveniently, sealing property is reliable, and standby observation clean-up port is used to observe and clear up the mid portion of sewage runner.

The specific embodiment: the specific embodiment of the present invention is elaborated below in conjunction with accompanying drawing:
Embodiment: the box heat exchanger of a kind of sewage is (referring to Fig. 2, Fig. 3, Fig. 4), it comprises casing 6, the two ends of casing 6 are provided with end plate 7, level is evenly distributed with laminate 8 in the casing 6, form runner between laminate 8 and the laminate 8, all vertically be provided with two rectangle deflection plates 17 in every laminar flow road, the length of two rectangle deflection plates 17 is less than the length 100～300mm (120～200mm the best) of laminate 8, the upper and lower side of rectangle deflection plate 17 links to each other with laminate 8, one end of one of them deflection plate 17 links to each other with a side of casing 6, and an end of another deflection plate 17 links to each other with the opposite side of casing 6.Runner is respectively clear water runner 9 and sewage runner 10, independent and adjacent between clear water runner 9 and the sewage runner 10, even the individual layer runner is the clear water runner, then double-layer channel is the sewage runner, if double-layer channel is the clear water runner, then the individual layer runner is the sewage runner, the fresh water pipeline elbow assembly 11 that passes through two ends between the adjacent clear water runner 9 respectively connects, form whole clear water runner, one end of ground floor clear water runner 9 is established clear water import 13, one end of last one deck clear water runner 9 is established clear water output 14, the sewage conduct elbow assembly 12 that passes through two ends between the adjacent sewage runner 9 respectively connects, form the entire sewage runner, an end of ground floor sewage runner 10 is established outlet of sewer 15, and an end in last one deck effluent stream road 10 is established sewage import 16.Clear water import 13 is adjacent with outlet of sewer 15, and sewage import 16 is adjacent with clear water output 14.The side casing of every layer of sewage runner 10 is provided with openable standby clean-up port 18, with the convenient mid portion of observing and clearing up the sewage runner, with anti-clogging.
During use, sewage enters upper end ground floor sewage runner 10 from sewage import 16, enter down in one deck effluent stream road 10 through the deflection plate baffling and by sewage conduct elbow assembly 12, enter to descend again in one deck effluent stream road 10 through the deflection plate baffling and by sewage conduct elbow assembly 12 again, in sewage enters last one deck effluent stream road, lower end 10, discharge by outlet of sewer 15.Clear water enters lower end last one deck clear water runner 9 from clear water import 13, enter in the last layer clear water runner 9 through the deflection plate baffling and by fresh water pipeline elbow assembly 11, enter again in the last layer clear water runner 9 through the deflection plate baffling and by fresh water pipeline elbow assembly 11 again, in clear water enters upper end ground floor clear water runner 9, discharge, realize clear water-sewage heat exchange by clear water output 14.According to the heat exchange amount requirement of concrete engineering, practicable series connection of the box heat exchanger of several sewage of the present utility model and in parallel the use.
