Stagewise condensing heat exchanger.
Background technology
Organic substance produces in medium industry be often taken as solvent at chemical industry, medicine, and a part of organic solvent is in pole
Gas just can be evaporated into, along with environmental requirement improves further, to rich in volatile organic gas also at a temperature of low
There is tightened up discharge standard, waste gas produced in preparation process typically can first have been carried out condensation process, then
Such as it is catalyzed oxidation or the purified treatment of multi-stage condensing recovery.And if condensation process can reach well to imitate
Really, subsequent treatment amount can be just significantly reduced.
Condensation separation method is to utilize the low-boiling characteristic of volatile organic matter, and after temperature reduces, boiling point is higher
Out, it is critical only that of this technique provides enough colds to make Organic substance condense to volatile organic matter condensation separation.Pass
Equipment that the multiple stage heat exchanger of system exists and the problem such as pipeline is the compactest, SR is big.
Document CN 103028269 A first borrow the condenser of upstream divided by most water solublity volatile organic matter
Separate out, then downstream water sprinkler be set utilize water sprinkler that the off-gas flows that passes through is sprayed water smoke, allow downstream
Condenser condenses out more water droplet and absorbs water solublity volatile organic matter.This method is unsuitable for organic repetition profit
With.
Cooling unit and mistake in CN 104390495 A, condensing heat exchanger primary structure includes condenser body, pipe
Cold unit, is mainly interposed between the steam heat-exchanging in heat exchanger tube in two canister unit by dividing plate and is respectively divided into two journeys,
Guarantee that each journey steam flow rate keeps uniform substantially.The condenser of this kind of device does not has condensate recovery device, application
Extensive, VOC is reclaimed in the most inapplicable and condensation.
CN 103822510 A mainly describes muitishell tubular heat exchanger, mainly will by sealing dividing plate
The shell side of heat transfer zone is divided into the plural separate sub-district of shell side heat exchange, and the independent sub-district of shell side heat exchange sets
There are independent shell-side fluid import and shell side fluid outlet.The design of this kind of device is for equipment cooling or the intensification temperature difference not
Time big the most applicable, but it seals the simple isolation of dividing plate, can not reduce the heat exchange energy of big temperature difference shell-side fluid
Amount loss, and this kind of equipment do not has a lime set collection device, inapplicable with the gas converting heat having lime set.
Summary of the invention
Defect that the purpose of the present invention is contemplated to overcome above-mentioned prior art to exist and provide one be applicable to rich in
The stagewise condensing heat exchanger of volatile organic gas.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of it is applicable to the stagewise condensing heat exchanger rich in volatile organic gas, flows including for gas to be condensed
Tube bank and surround tube bank and cooling fluid flowing cylinder, this cylinder is divided into multistage canister unit from top to bottom,
Every section of canister unit is equipped with independent shell side fluid inlet and shell side fluid outlet, between two adjacent canister unit
Being tightly connected by middle insulating course, the tube bank between adjacent two canister unit through insulating course and is connected.
Described middle insulating course includes connecting tube and insulation surface layer, and described connecting tube is through insulation surface layer, and connects
Tube bank between logical adjacent two canister unit.Connecting tube can also use the high-strength insulation equally with heat-insulating capability
Material is made, and insulation surface layer can be multi-layer compound structure.
Described middle insulating course is connected with canister unit integral type.
Described cylinder is divided into top canister unit and lower cylinder unit two sections, wherein, the shell of top canister unit
The temperature of Cheng Liuti is less than the temperature of the shell-side fluid of lower cylinder unit.
The shell-side fluid of described top canister unit is that room temperature cools down water, and the shell-side fluid of lower cylinder unit is low
Temperature chilled water.
Described lower cylinder unit is provided with expansion joint.
In the gas access being arranged above and restraining connection of described cylinder, it is also equipped with collection in the bottom of cylinder
Flow container, the sidepiece of liquid collecting tank is additionally provided with gas outlet, and bottom is provided with condensate outlet.
It is provided with far transmission level meter in described liquid collecting tank, at condensate outlet, is additionally provided with pneumatic operated valve, described teletransmission
Liquidometer is all connected with automatic control system with pneumatic operated valve.
Described tube bank is straight tube structure.
The present invention by being divided into top canister unit and lower cylinder unit by shell side, and two independent canister unit divide
Other and tube side forms heat exchange subregion cooling unit and condensing unit.Top canister unit is can be room temperature cooling heat transferring
Canister unit, lower cylinder unit is can be condensation at low temperature heat exchanger tube body unit, it is also possible to set according to actual needs
Put the heat transfer temperature difference of top cylinder and lower cylinder.So, the gas condensation process first passes through the normal of cooling unit
Temperature cooling, portion gas condenses, and condenses further along with the gas of incoagulability enters condensing unit, the most permissible
Being promoted by incoagulable gas makes lime set collect faster.In lower cylinder unit, shell-side fluid is freezing water,
This section is provided with expansion joint, and what minimizing cold and hot liquids flowing caused can effectively reduce volatility to equipment injury simultaneously has
The temperature of machine thing, reaches well to condense recovery purpose.
Compared with prior art, the invention have the advantages that
(1) by the setting of multistage shell side, it is possible to achieve utilize the space of a heat transmission equipment and heat exchange area to reach
To the purpose of series connection heat transmission equipment, effectively save equipment cost, the connection between equipment and pipeline can be reduced, save
Installation cost, can also reduce because multiple stage condenser is used in conjunction the fluid resistance caused simultaneously, increase the heat transfer system of condenser
Number, improves heat exchange efficiency, and the condensation that can well improve volatile organic matter is reclaimed.
(2) fluid between each section of shell side all has individually import and export, and improve heat transmission equipment utilizes scope,
This kind of heat transmission equipment can need to change the temperature difference of heat transferring medium according to different technique, reaches heat transfer effect.
(3) heat transfer coefficient of heat transmission equipment is improved: in the middle of the present invention, insulating course is to comprise tube bank and heat-preservation cotton layer,
Wherein tube bank is connected with the tube bank of upper and lower canister unit, and insulating course and upper lower shell are the connected modes of integral type.
The infiltration of middle insulating course different cold flow bodies in being possible to prevent upper and lower cylinder shell side and temperature shadow each other
Ring, it is to avoid owing to the excessive generation of fluid temperature difference cold in upper and lower cylinder can cause the phenomenon of the cold fluid freeze of one of which.
Insulation surface layer in middle insulating course can effectively reduce the heat transfer between the cold flow body in upper and lower cylinder, reduces cold
The heat loss of fluid, effectively utilizes the cold of cold flow body, improves heat exchange efficiency.The expansion arranged on the cylinder of its underpart
Joint is prevented from the impact for equipment barrel material of expanding with heat and contract with cold, and improves service life and the utilization rate of equipment.
