Description
Technical field
The utility model relates to heat exchanger, is specifically related to a kind of parallel heat exchanger.
Background technology
At present, be carry out dry collagen stoste with spray drying tower producing last one technique of collagen.Its principle is first by purification of air, then is pumped in heat exchanger, and the high-temperature steam sent here with boiler to the temperature needed, is carried out these air heat baking by the collagen that rotary atomizer is atomized into nano sized particles in spray tower and dries up dry delivering to.
As shown in Figure 1, heat exchanger is made up of 4 heat exchange units the steam heat-exchanger of original use, and is provided with the interior pipe of coiling in the inner chamber of these heat exchange units.4 heat exchange units are for being composed in series, namely connected by pipe joint between each heat exchange unit, temperature regulates inconvenient, as long as and 1 heat exchange unit in 4 heat exchange units goes wrong, just must close down whole heat exchanger, thus cause follow-up spray drying tower also cannot normally work.
Utility model content
For there being the defect of technology on overcoming, the purpose of this utility model is intended to propose a kind of parallel heat exchanger can being convenient to keep in repair, do not affect production work.
For achieving the above object, the utility model adopts following technical scheme:
A kind of parallel heat exchanger, is characterized in that: this heat exchanger body is 4 heat exchange units with inner chamber arranged vertically, is provided with the interior pipe of coiling in the inner chamber of heat exchange unit; The upper end, sidewall side of each heat exchange unit described has steam inlet, and the lower end of opposite side has steam gas outlet; Described steam inlet is connected by interior pipe with steam gas outlet; Each steam inlet place described connects the steam branch pipe road with magnetic valve, each communication channel main steam header road, steam branch pipe road; Each steam gas outlet place described connects the waste vapour branch pipe(tube) with magnetic valve, and each waste vapour branch pipe(tube) is communicated with waste vapour main pipeline; The bottom of described heat exchanger has cold air air inlet, and top has hot-air gas outlet.
Explanation and the further scheme of such scheme are as follows:
1., in such scheme, described interior pipe is U-shaped coiled structure.
2., in such scheme, the pipeline that described cold air air inlet connects also is equipped with the purifier purified air.
3., in such scheme, described cold air air inlet is connected with air pump, and air is introduced into air pump, then enters cold air air inlet through purifier.
Because technique scheme is used, the utility model compared with prior art has following advantages:
Pipe in original tandem heat exchange changes into parallel by the utility model, and has installed magnetic valve on each mouth of pipe, has like this to utilize to control vapours inlet.And if wherein any one heat exchange unit is out of order, this heat exchange unit can be closed at once, and also not affect the normal production of other three heat exchange units.
Accompanying drawing explanation
Fig. 1 is the structural representation of series heat exchanger in prior art;
Fig. 2 is structural representation of the present utility model.
In above accompanying drawing: 1, heat exchanger; 2, inner chamber; 3, heat exchange unit; 4, interior pipe; 5, steam inlet; 6, steam gas outlet; 7, magnetic valve; 8, steam branch pipe road; 9, main steam header road; 10, waste vapour branch pipe(tube); 11, waste vapour main pipeline; 12, cold air air inlet; 13, hot-air gas outlet; 14, purifier; 15, air pump.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described:
Embodiment: shown in Figure 2:
A kind of parallel heat exchanger, this heat exchanger 1 main body is 4 heat exchange units 3 with inner chamber 2 arranged vertically, is provided with the interior pipe 4 of coiling in the inner chamber 2 of heat exchange unit 3; Interior pipe 4 can adopt the copper pipe or stainless steel tube that heat exchange property is good; The upper end, sidewall side of each heat exchange unit 3 described has steam inlet 5, and the lower end of opposite side has steam gas outlet 6; Described steam inlet 5 is connected by interior pipe 4 with steam gas outlet 6; Each steam inlet 5 place described connects the steam branch pipe road 8 with magnetic valve 7, and each steam branch pipe road 8 is communicated with main steam header road 9; Each steam gas outlet 6 place described connects the waste vapour branch pipe(tube) 10 with magnetic valve 7, and each waste vapour branch pipe(tube) 10 is communicated with waste vapour main pipeline 11; The bottom of described heat exchanger 1 has cold air air inlet 12, and top has hot-air gas outlet 13; Described interior pipe 4 is U-shaped coiled structure; The pipeline that described cold air air inlet 12 connects also is equipped with the purifier 14 purified air; Described cold air air inlet 12 is connected with air pump 15, and air is introduced into air pump 15, then enters cold air air inlet 12 through purifier 14.
Boiler Steam through entering in main steam header road 8, then enters each steam branch pipe road 9 by main steam header road 8, opens magnetic valve 7.Steam enters the inner chamber 2 of heat exchange unit 3 from steam inlet 5.Open air pump 15, outdoor cold air was pumped in heat exchange unit 3 from cold air air inlet 12 after entering purifier 14 purification, be heated to temperature required by the vapours of circulation in pipe 4 in heat exchange unit 3 inner chamber 2, finally discharge from hot-air gas outlet 13 and enter in spray drying tower.Due to each steam branch pipe road 8 and waste gas branch pipe(tube) 10 having magnetic valve 7 to control, therefore according to need of production, the flow that steam regulation enters can be carried out.If wherein any one heat exchange unit 3 breaks down, only need the two ends magnetic valve 7 of closing this heat exchange unit 3 in time that this heat exchange unit 3 can be made to quit work, do not affect again the work of other heat exchange units 3, ensure that the normal work of heat exchanger 1.The heat exchange unit 3 broken down then can be left to after production terminates and keep in repair.
Above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences done according to the utility model change or modify, and all should be encompassed within protection domain of the present utility model.
