Description
Technical field
It is specifically a kind of to be heated for ClO 2 solution the utility model is related to chlorine dioxide heating equipment technical field
Heat-exchanger rig.
Technical background
Chlorine dioxide is extremely strong oxidant, can corrode all metals in addition to platinum, tantalum and titanium.In normal temperature and pressure
Under, chlorine dioxide is orange-yellow gas, has the irritation pungent similar to chlorine and ozone mixture, and boiling point is 11 DEG C, freezing point
It is -59 DEG C.Gaseous chlorine dioxide is unstable, and chlorine dioxide gas concentration cannot be too high, and partial pressure will be controlled in 100mmHg (absolute pressure)
Hereinafter, it even explodes if partial pressure can be decomposed more than 100mmHg.Aqueous solution of chlorine dioxide is then relatively stable, and aqueous temperature is got over
Low chlorine dioxide dissolving degree is higher, more stable.Association with pulp bleaching production line needs the higher ClO 2 solution of concentration, therefore prepares
ClO 2 solution temperature it is relatively low (generally 10-14 DEG C), and ClO 2 bleaching technological requirement reaction temperature is generally 70
DEG C or so, steam consumption is bleached to save, needs to carry out using the waste heat of filtrate before ClO 2 solution enters bleaching process
Heating.
Since ClO 2 solution has strong corrosive, and temperature is excessively high that chlorine dioxide partial pressure can be caused high, Yi Fa
Therefore raw safety accident, is badly in need of manufacture one kind and is not only resistant to chlorine dioxide corrosion, but also can effectively control ClO 2 solution after heating
Temperature ensures heat-exchanger rig of the chlorine dioxide pressure in safe range after heating.
Utility model content
The technical problem to be solved by the utility model is to provide it is a kind of for ClO 2 solution heating heat-exchanger rig,
The heat-exchanger rig had not only been resistant to chlorine dioxide corrosion, incrustation easy to clean, but also can effectively control the ClO 2 solution temperature after heating
Degree ensures that ClO 2 solution pressure is in safe range in device.
The utility model adopts the following technical solution solves above-mentioned technical problem：
The utility model is used for the heat-exchanger rig of ClO 2 solution heating, it includes tubular heat exchanger, tubular heat exchanger
Housing in be equipped with the continuous tubulation of multistage, shell side and tube side, the inlet and outlet piping connection shell of ClO 2 solution are formed in housing
Journey, the inlet and outlet piping of filtrate connect tube side, temperature transmitter and pressure relief device are equipped on the outlet conduit of ClO 2 solution,
Temperature control valve (TCV) is installed on the inlet pipeline of filtrate.
Housing, the tubulation of the tubular heat exchanger are made of titanium.
The utility model device has the advantages that：
1) tubulation for the heat-exchanger rig that the utility model uses and housing are made of titanium, anti-chlorine dioxide corrosion
It can be strong；
2) shell side of the tubular heat exchanger of the utility model walks ClO 2 solution, and tube side walks filtrate, and filtrate is in tubulation
Conveniently physical cleaning mode can be selected in inner wall incrustation, when cleaning；
3) a set of temperature control device is configured in the utility model heat-exchanger rig, can effectively control the ClO 2 solution temperature after heating
Degree is in the range of technological requirement；
4) a set of pressure relief device is configured as emergency service in the utility model heat-exchanger rig, when ClO 2 solution temperature tune
Valve or temperature transmitter failure are saved, when causing ClO 2 solution temperature after heating excessively high, and then enabling pressure superelevation in device
Timely pressure release, avoids safety accident.

Specific embodiment
As shown in Figure 1, the utility model is used for the heat-exchanger rig of ClO 2 solution heating, including tubular heat exchanger 1, temperature
Spend regulating valve 2, temperature transmitter 3, pressure relief device 4, chlorine dioxide inlet tube 5, chlorine dioxide outlet tube 6, filtrate inlet tube 7,
Filtrate outlet tube 8.The continuous tubulation of multistage is equipped in the housing of tubular heat exchanger 1, shell side and tube side, titanium dioxide are formed in housing
Chlorine inlet tube 5 and chlorine dioxide outlet tube 6 are connected with shell side, and filtrate inlet tube 7 and filtrate outlet tube 8 are connected with tube side,
Temperature transmitter 3 and pressure relief device 4 are installed, filtrate inlet tube 7 is equipped with temperature control valve (TCV) 2 on chlorine dioxide outlet tube 6.
During work, low temperature ClO 2 solution (temperature is 10-14 DEG C) enters tubular heat exchanger from chlorine dioxide inlet tube 5
1 shell side, filtrate (about 70 DEG C) enter the tube side of tubular heat exchanger 1 from filtrate inlet tube 7, and ClO 2 solution is being arranged with filtrate
It exchanges heat in heat exchange of heat pipe 1.ClO 2 solution after heat exchange enters bleaching process through chlorine dioxide outlet tube 6, and filtrate is then through filter
Liquid outlet tube 8 drains into trench.
In device operational process, the ClO 2 solution temperature after heat exchange passes through 2 groups of temperature transmitter 3 and temperature control valve (TCV)
Into temperature control device be monitored, control, the ClO 2 solution temperature stabilization after heat exchange can be made in the range of technological requirement.If
There is the temperature control valve (TCV) of ClO 2 solution or temperature transmitter failure, cause ClO 2 solution excessively high, and make in device
During pressure superelevation, pressure relief device 4 will releasing pressure automatically, it is ensured that system safety.
Housing, the tubulation for the tubular heat exchanger 1 that the utility model uses are titanium, and resistance to chlorine dioxide corrosion is strong.When
After the tubulation inner wall incrustation of tubular heat exchanger 1, both ends end socket is split out, directly tubulation is cleaned with giant, both facilitated
It is again quick.
