Description
Technical field
The utility model relates to a kind of chemical machinery device, refers in particular to a kind of device that utilizes heat of high temperature to reclaim spent lye.
Background technology
In the chemical industry of China, alkali industry is a very big part, but alkali industry heavy polluted industry often.Especially the recycling of salkali waste is the content that China environmental protection department pays close attention to always.It is a kind of method commonly used that heat change method comes thickened waste alkali lye; But the heat utilization efficiency in the reclaimer that present China is adopted is lower, and cost recovery is higher, but also has environmental pollution problems; Especially for this chemical feed liquid; The as easy as rolling off a log phenomenons such as waste that cause corrosion on Equipment and energy consumption, enterprise is in order to increase economic efficiency, and how the energy efficient spending is a very important ring.
Summary of the invention
The utility model has proposed a kind of effectively energy-conservation device to deficiency of the prior art, and the energy consumption that can be implemented in the chemical enterprise through the utility model reclaims, and increases economic efficiency.The utility model is with regard to reclaiming the problem that exists in the industry at salkali waste at present, through existing equipment is improved, can effectively handle the device that salkali waste reclaims.
The utility model is achieved through following proposal: a kind of spent lye retracting device; Comprise into hot fluid import, hot liquid outlet, spent lye import, spent lye outlet; It is characterized in that the hot fluid chamber being arranged in the device, reclaim the chamber, go out the hot fluid chamber, wherein the chamber of recovery is positioned at into the hot fluid chamber and goes out in the middle of the hot fluid chamber; The set inside that reclaims the chamber has some seamless steel pipes, and two terminations of seamless steel pipe are connected to into the hot fluid chamber and go out the hot fluid chamber; Spent lye import, spent lye outlet are positioned on the locular wall that reclaims the chamber.
As preferably; The top of the recovery chamber in above-mentioned a kind of spent lye retracting device has a row hole, chamber, can reduce reclaiming indoor air pressure, to guarantee the normal operation of equipment; If pressure is too high; Very easily cause phenomenons such as blast, also can the equipment top be installed by an automatic exhaust steam valve, then effect may be better.
As preferably, the below of above-mentioned a kind of spent lye retracting device is equipped with leg, can break away from ground to whole device like this; And the ground of chemical enterprise generally can be moist, alkali lye touches device bottom; Very easily cause corrosion,, then can prevent corrosion on Equipment so leg is set.In order better to reclaim heat etc., be evenly distributed with the seamless steel pipe that some diameters are 32 ~ 50mm, better effects if in the recovery chamber interior.In the utility model, do not have special requirement for the profile of entire equipment, in actual use, can be oval-shaped, or circular, or rectangular all be to obtain effect preferably.For the content locellus of equipment and the requirement of seamless steel pipe then is emphasis.
The beneficial effect of the utility model: the equipment through the utility model reclaims the concentration height that spent lye can be obtained heat recovery rate height, spent lye, utilizes environmental protection, energy savings etc.

The specific embodiment
Specifically describe below in conjunction with the enforcement of accompanying drawing the utility model:
According to structure shown in the accompanying drawing 1; Make a spent lye retracting device; Comprise into hot fluid import 10, hot liquid outlet 5, spent lye import 4, spent lye outlet 1, hot fluid chamber 9 is wherein arranged in the device, reclaim chamber 8, go out hot fluid chamber 6, wherein reclaim chamber 8 and be positioned at into hot fluid chamber 9 and go out in the middle of the hot fluid chamber 6; The set inside that reclaims chamber 8 has some seamless steel pipes 2, and two terminations of seamless steel pipe 2 are connected to into hot fluid chamber 9 and go out hot fluid chamber 6; Spent lye import 4, spent lye outlet 1 are positioned on the locular wall that reclaims chamber 8; Above recovery chamber 8, have a steam vent 3; Below device, leg 7 is installed.
In the actual use of the utility model, hot fluid mainly is to utilize the flue gas of high temperature to come heat supply.Entire equipment is to be fixed in the building through leg 7, and flue enters into into hot liquid chamber 9 through hot fluid import 10, and the effluent gas temperature of this moment is 360 ℃, and inlet flow rate is 50m
3, be communicated with seamless steel pipe 2 because of entering hot fluid chamber 9, so the flue gas of a large amount of heat enters in the seamless steel pipe 2, enter into out hot fluid chamber 6 then, after hot fluid outlet 5 is discharged, reduce to about 80 ℃ from the effluent gas temperature that outlet is discharged.The spent lye of this moment then moves toward roughly opposite direction with hot flue gases, and spent lye enters into from spent lye import 4 and reclaims chamber 8, and the spent lye concentration of this moment is 8%; Temperature is a normal temperature, and about 25 ℃, flow is 3T/H; After spent lye passes through whole recovery chamber 8; Discharge from spent lye outlet 1, the spent lye temperature of this moment is 100 ℃ again, and the spent lye concentration of outlet is about 26%.In this heat recovering process, because of spent lye has carried out heat exchange with flue gas in reclaiming chamber 8, the spent lye temperature raises, and steam is mutinied into steam from steam vent 3 discharges, causes the concentration of spent lye constantly to be concentrated, and discharges at last.
In the utility model,, obtain recovering effect preferably because the increase of heat exchange area and the control of rate of flow of fluid make heat utilization efficiency improve greatly.Certainly, in the utility model, the overall dimensions of equipment can be in time adjusted, the treating capacity of whole spent lye can be improved according to the output of the actual spent lye of factory, and the recovery of heat.
