The utility model discloses convenient to use, heat exchange efficiency is high, and is corrosion -resistant.
Description
Technical field
The utility model relates to a kind of heat reclaim unit in trade effluent.
Background technology
Chemical plant, steel mill, thermal power plant can produce the trade effluents such as substantial amounts of cooling water or washing slag water in process of production, and this kind of sewage itself carries substantial amounts of heat.Under normal circumstances, these heats can be re-used by heat exchange.In process of production, pipeline is blocked in order to prevent fouling, cooling water or washing slag water usually contain acid, so that the aobvious acidity of sewage, as carried out heat exchange with common heat exchanger, then it is easy to etching apparatus, in addition containing substantial amounts of impurity in sewage, the most easily causes the heat exchanger tube blocking that caliber is less.
Utility model content
The purpose of this utility model is to provide a kind of easy to use, and heat exchange efficiency is high, corrosion resistant heat reclaim unit in trade effluent.
Of the present utility model adopt the following technical scheme that
A kind of heat reclaim unit in trade effluent, it includes the immersion heat-exchanger rig of oral siphon road, outlet pipeline, connection oral siphon road and outlet pipeline and is arranged on the circulating pump on oral siphon road；Described immersion heat-exchanger rig includes heat exchange coil, is arranged on heat exchange coil two ends and for the connecting line connected with oral siphon road and outlet pipeline；It is provided with diving mixer on the lateral wall of described connecting line.
Further, connected by shell-and-tube heat exchanger between entrance and the outlet of outlet pipeline on described oral siphon road.
Further, the quantity of described immersion heat-exchanger rig is more than one.
Further, described heat exchange coil includes the horizontal coiled pipe of several parallel connections, and one end of each described horizontal coiled pipe is connected with oral siphon road by connecting line, and the other end is connected with outlet pipeline by connecting line.
Further, each described heat exchange coil includes the plural horizontal coiled pipe being parallel to each other.
Further, described horizontal coiled pipe is that PE material is made.
The beneficial effects of the utility model are: immersed by heat exchange coil and carry out heat exchange in trade effluent, and heat exchange coil uses PE material to make, and compared to traditional shell-and-tube heat exchanger, not only anticorrosion, also big with the contact area of sewage, heat exchange efficiency is high.Owing to being provided with diving mixer outside connecting line, the turbulent extent of sewage in whole cesspool can be improved, improve heat transfer effect.Connected by shell-and-tube heat exchanger between entrance and the outlet of outlet pipeline on oral siphon road, heat can be exchanged to other with in hot pipe network.Immersion heat-exchanger rig and horizontal coiled pipe all use parallel way to connect, it is easy to individually shutdown maintenance or replacing.

Wherein, 1 oral siphon road, 2 outlet pipelines, 3 circulating pumps, 4 heat exchange coils, 5 connecting lines, 6 diving mixers, 7 shell-and-tube heat exchangers, 8 horizontal coiled pipes.
Detailed description of the invention
Shown in Fig. 1 ~ 4, a kind of heat reclaim unit in trade effluent, it includes oral siphon road 1, outlet pipeline 2, connection oral siphon road 1 and the immersion heat-exchanger rig of outlet pipeline 2 and the circulating pump 3 being arranged on oral siphon road 1；Described immersion heat-exchanger rig includes heat exchange coil 4, is arranged on heat exchange coil 4 two ends and for the connecting line 5 connected with oral siphon road 1 and outlet pipeline 2；It is provided with diving mixer 6 on the lateral wall of described connecting line 5.
Connected by shell-and-tube heat exchanger 7 between entrance and the outlet of outlet pipeline on described oral siphon road 1.
The quantity of described immersion heat-exchanger rig is more than one.
Described heat exchange coil 4 includes the horizontal coiled pipe 8 of several parallel connections, and one end of each described horizontal coiled pipe 8 is connected with oral siphon road 1 by connecting line 5, and the other end is connected with outlet pipeline 2 by connecting line 5.
Each described heat exchange coil 4 includes the plural horizontal coiled pipe 8 being parallel to each other.Described horizontal coiled pipe 8 is made for PE material.
During use, immersion heat-exchanger rig is immersed in hot industry cesspool, recirculated water is pumped in connecting line 5 by oral siphon road 1 by circulating pump 3, recirculated water is entered in horizontal coiled pipe 8 by connecting line 5 again, hot industry sewage is by the circulating water heating in horizontal coiled pipe 8, heated recirculated water is entered in shell-and-tube heat exchanger 7 by outlet pipeline 2, then returns to after heat exchange in oral siphon road 1.Heat can be exchanged in other heat supplying pipelines by shell-and-tube heat exchanger 7, thus completes the heat recovery and utilization of trade effluent.In heat transfer process, the sidewall of connecting line 5 is provided with diving mixer 6, can be stirred by the high temperature sewage near heat exchanging coil pipe 4, the turbulent extent of sewage near formula of improving the standard serpentine coil 8, thus strengthen heat transfer effect.The horizontal coiled pipe 8 of multichannel PE material forms heat exchange coil 4, increases the contact area with high temperature sewage, improves heat exchange efficiency.PE pipe is corrosion-resistant, compared to PB pipe, PPR pipe coefficient of heat transfer height.
Above example only in order to the technical solution of the utility model to be described, is not intended to limit；Although the utility model being described in detail with reference to previous embodiment, it will be understood by those within the art that: the technical scheme described in previous embodiment still can be modified by it, or wherein portion of techniques feature is carried out equivalent；And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of the utility model embodiment technical scheme.
