Description
Technical field
The utility model is related to heat transmission equipments, and in particular to a kind of tubular heat exchanger.
Background technology
It in bio-fermentation process, generally requires to inject the air of the thermophilic of fresh drying into fermentation tank, to ensure
The product quality of fermenting and producing line.In order to discharge the moisture included in injection air, need to drop air themperature by cooling driers
To pressure leak source, condensed water is precipitated, air is dried, but since condensed water is precipitated after, air themperature is relatively low, if not right
Air heats up, then can make a big impact to the product quality of fermenting and producing line, and different fermenting and producing lines is to note
The temperature of the air entered, which has, compares strict requirements.
Utility model content
The utility model for the technical problems in the prior art, provide it is a kind of safety heating and being capable of accurate temperature control
Tubular heat exchanger.
The technical solution that the utility model solves above-mentioned technical problem is as follows：
A kind of tubular heat exchanger, including
Housing, the housing is interior to be equipped with multiple tubulations, and the housing upper and lower ends are equipped with tube sheet, and the housing is made to form one
A annular seal space, the lower part of the housing side wall are equipped with the air intake duct connected with the enclosure interior, the upper part of the housing side
Wall is equipped with the air exhaust duct connected with the enclosure interior；
The tube sheet is equipped with multiple through-holes for installing the tubulation and making the tubulation both ends open, the tube sheet
On end socket is installed, positioned at the housing upper end the end socket be equipped with steam inlet duct, positioned at the housing lower end
The end socket be equipped with steam exhaust pipe；
Temperature sensor is equipped in the air exhaust duct, the air exhaust duct is equipped with flow control valve.
Further, multiple tubulations in the housing are annularly arranged around the central axes of the housing.
Further, multiple baffle plates being staggered are additionally provided in the housing.
Further, further include controller, prestore temperature range threshold value in the controller, the controller respectively with institute
Temperature sensor and flow control valve electrical connection are stated, for the housing interior air-flow temperature control detected according to the temperature sensor
The flow of flow control valve.
The beneficial effects of the utility model are：It can be to carrying out safe heating by air after cooling driers bleed and can
Accurate temperature control.
Description of the drawings
Fig. 1 is a kind of structure diagram of tubular heat exchanger provided by the utility model.
In attached drawing, parts list represented by the reference numerals are as follows：
1st, housing, 2, tubulation, 3, tube sheet, 4, air intake duct, 5, air exhaust duct, 6, end socket, 7, steam inlet duct, 8,
Steam exhaust pipe, 9, temperature sensor, 10, flow control valve, 11, baffle plate, 12, controller.
Specific embodiment
The principle and feature of the utility model are described below in conjunction with attached drawing, example is served only for explaining this practicality
It is novel, it is not intended to limit the scope of the utility model.
Fig. 1 is a kind of structure diagram of tubular heat exchanger provided by the utility model, as shown in Figure 1, a kind of tubulation
Formula heat exchanger, including
Housing 1, the housing 1 is interior to be equipped with multiple tubulations 2, and 1 upper and lower ends of housing are equipped with tube sheet 3, make the housing 1
An annular seal space is formed, 1 lower sides of housing are equipped with the air intake duct 4 connected with the enclosure interior, the shell
1 upper portion side wall of body is equipped with the air exhaust duct 5 connected with the enclosure interior；
The tube sheet 3 is equipped with multiple through-holes for installing the tubulation 2 and making 2 both ends open of tubulation, described
End socket 6 is installed, the end socket 6 positioned at the housing upper end is equipped with steam inlet duct 7, positioned at described on tube sheet 3
The end socket 6 of housing lower end is equipped with steam exhaust pipe 8；
Temperature sensor 9 is equipped in the air exhaust duct 5, the air exhaust duct 5 is equipped with flow control valve 10.
Further, multiple tubulations 2 in the housing are annularly arranged around the central axes of the housing.
Further, multiple baffle plates 11 being staggered are additionally provided in the housing.
Further, controller 12 is further included, temperature range threshold value, the controller difference are prestored in the controller 12
It is electrically connected with the temperature sensor 9 and flow control valve 10, for the housing interior air-flow detected according to the temperature sensor
Temperature controls the flow of flow control valve, for example the temperature range that prestores is 30~35 DEG C, when temperature sensor monitors to air are arranged
When tracheal strips air themperature is less than 30 DEG C, then air exhaust duct flow is reduced by controller control flow control valve, make reduction empty
Speed of the air-flow through heat exchanger increases heat-exchange time, is higher than if working as air themperature in temperature sensor monitors to air exhaust duct
At 35 DEG C, then by controller control flow control valve increase air exhaust duct flow, accelerate the speed that air flows through heat exchanger, subtract
Few heat-exchange time.
The beneficial effects of the utility model are：It can be to carrying out safe heating by air after cooling driers bleed and can
Accurate temperature control.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all in this practicality
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
