Technical field

The utility model relates to the UTILIZATION OF VESIDUAL HEAT IN in the thermal material cooling procedure, belongs to the agitated reactor residual heat using device.

Background technology

In a lot of small-sized chemical industry synthetic operations, chemical reaction all need carry out under the condition of heating, after reaction finishes, material must be under the effect of natural wind or cooling water cool to room temperature.In the chemical reaction operating process in the small-sized batch (-type) chemical plant of the overwhelming majority, reaction and cooling are two processes independently mutually.Course of reaction has independently heater, and cooling procedure has independently cooling water recirculation system.Consider that from the angle of heat energy utilization make chemical reaction maintain the required heat energy that provides under the assigned temperature, major part has all been lost in the process of cooling.Moreover, since bigger at the output and the backwater temperature difference of cooling water recirculation system, often need bigger recirculated water reservoir, and heat exchange efficiency is not high.On the other hand, in reaction process, owing to will cold material be heated to the reaction temperature of appointment, often need long reaction time, thereby prolonged the time of single still reaction.

The utility model content

In view of existing in prior technology the problems referred to above, the utility model is intended to disclose a kind of agitated reactor residual heat using device, makes full use of the waste heat in the thermal material cooling procedure, improves heat exchange efficiency.

The technical scheme of the utility model is achieved in that

A kind of agitated reactor residual heat using device is characterized in that said agitated reactor residual heat using device is made up of material pipe preheating sleeve pipe, jacketed cone-type mixer and water circulating pipe; Cooling water pipeline delivery port in the said jacketed cone-type mixer chuck is connected to the water inlet of material pipe preheating sleeve pipe lower end through circulating water pipeline; The delivery port of material pipe preheating sleeve pipe upper end connects drainage pipeline, and said water circulating pipe is provided with safety-valve and valve; Said material pipe preheating sleeve pipe is installed on the material pipe outer wall; Cooling water pipeline in the said jacketed cone-type mixer chuck is to rise around cone-type mixer wall spiral to arrange.

The beneficial effect of the utility model is:

(1) cone-type mixer with jacketed comes the thermal material of accomplishing reaction is lowered the temperature; Awl row mixer stir and chuck under the acting in conjunction of cooling water; Make cooling water fully collect the heat that discharges in the thermal material temperature-fall period, when quickening temperature-fall period, improve the efficient of preheating material.

(2), realize that in the batch (-type) Chemical Manufacture, the purpose that shortens reaction time and cool time has improved production efficiency through the combination of water circulation cooling and preheating.

Description of drawings

2 in the total accompanying drawing of the utility model, wherein,

Fig. 1 is the utility model agitated reactor residual heat using device structural representation;

Fig. 2 is that the cooling water circular flow of jacketed cone-type mixer is to sketch map;

Among the figure, 1, material pipe preheating sleeve pipe, 2, the agitated reactor paddle, 3, agitated reactor; 4, agitated reactor heating jacket, 5, the jacketed cone-type mixer, 6, circulating water pipeline, 7, safety-valve; 8, valve, 9, material pipe, 10, the conduction oil input channel, 11, the conduction oil output channel.

The specific embodiment

A kind of agitated reactor residual heat using device shown in Fig. 1~2, is made up of material pipe preheating sleeve pipe 1, jacketed cone-type mixer 5 and water circulating pipe 6; Cooling water pipeline outlet in said jacketed cone-type mixer 5 chucks is received the water inlet of material pipe preheating sleeve pipe 1 lower end through circulating water pipeline 6; The delivery port of material pipe preheating sleeve pipe (1) upper end connects drainage pipeline, and said water circulating pipe 6 is provided with safety-valve 7 and valve 8; Said material pipe preheating sleeve pipe 1 is installed on material pipe 9 outer walls; Cooling water pipeline in said jacketed cone-type mixer 5 chucks is to rise around cone-type mixer wall spiral to arrange (like Fig. 2).

Thermal material system after reaction finishes in agitated reactor 3 enters into jacketed cone-type mixer 5; The flow direction of cooling water is designed to around the spiralling mode of tapered wall (like Fig. 2) in the chuck of cone-type mixer; Closed safe valve 7, Open valve 8 starts jacketed cone-type mixer 5; Cooling water is cooling water pipeline in water pump is passed into jacketed cone-type mixer 5 chucks; Under this condition, jacketed cone-type mixer 5 inner thermal materials can quicken cooling and evenly cooling, and thermal material can be made heat exchange efficiently in the process neutralization of cooling through the cooling water of mixer chuck; Temperature raises behind the heat of cooling water acquisition thermal material, and the hot water of rising temperature can be through material pipe preheating sleeve pipe 1 with the material preheating.

Embodiment 1

Assess improved effect through one day production process below.During the reaction of first still, add material, start the conduction oil circulating heater then, agitated reactor is heated according to original normal mode.The material system was heated to 90 ℃ of stirring reactions after 1 hour, and the material system is transferred to the jacketed cone-type mixer, started the agitating device of cooling water recirculation system and cone-type mixer.At this moment; The water temperature of the position of A shown in Fig. 1 is 20 ℃ of room temperatures, has just transferred to temperature of charge in the jacketed cone-type mixer up to 90 ℃, under cooling water and cone-type mixer stirring action; System is cooled off rapidly; And the heat of a large amount of absorption systems of cooling water of process cone-type mixer chuck, the water temperature of exit B test can reach 60 ℃, with the water pipe feeding material pipe preheating sleeve pipe here.At this moment, when the raw material of second still reaction passed through heating jacket, temperature can rise, and through measuring and calculating, the temperature of solid material can rise 16 ℃, and the temperature when solvent enters into agitated reactor can improve 10 ℃.Because the temperature of material and solvent is able to preheating, when second still reacted, being heated to 90 ℃ of needed times of reaction temperature had shortened 8 minutes.Simultaneously, enter into the water temperature that recirculated water stores water tank from raw material heating jacket outlet D and be reduced to about about 40 ℃.At this moment, because cyclic water tank Inlet and outlet water temperature difference has only 20 ℃.Under onesize water tank, to compare for 40 ℃ with the cooling range of directly returning from cone-type mixer originally, the temperature that recirculated water stores water tank does not have tangible rising.

Since the reaction of second still, process can as above be described, utilize the collected heat of last process system cooling successively, the raw material in next still reaction is carried out preheating.

We carry out the energy and time-related evaluation to 24 hours effect of cyclic production, and the result shows that 8 minutes times are practiced thrift in average every still reaction, can produce a still every day more, and yield in unit time improves 7%.From the power consumption measuring and calculating, the power consumption of unit interval saves 10%, and the power consumption that is converted into specific yield saves 16%.
