Problems solved by technology

[0003] 1. Adopting single-reactor processing method, the energy consumption is very high, and the environmental protection is not good
[0004] 2. The liquid substance to be treated is in a static or micro-flow state. The liquid substance in this state cannot be heated evenly, and the heating rate is slow, which will greatly affect the evaporation efficiency; if the height or volume of the processing device is large, it will be more The overall effect cannot be guaranteed
[0005] 3. The liquid substance to be treated is in a static or micro-flow state, which will make the inside of the evaporation tank prone to fouling and other conditions under long-term use, which will affect the overall service life and heat exchange efficiency
[0006] 4. The evaporating tank generally adopts a single-layer structure, and the temperature maintenance is not good, resulting in low evaporation efficiency and affecting the overall evaporation effect

Embodiment 1

[0059] Example 1: see figure 1 , in this embodiment, include three reactors as reactors, i.e. the first reactor 1001, the second reactor 1002 and the third reactor 1003, it can be understood that the number of reactors can also be multiple, this Also within the protection scope of the present invention. The present invention utilizes a plurality of reactors to carry out corresponding heat exchange step by step.

[0060] Step S1: The sludge to be treated (normal temperature, 20° C.) enters the stirring tank 1 of the first reaction kettle 1001 , and the heat exchange chamber 2 corresponding to the first reaction kettle 1001 is filled with circulating water. Turn on the circulation pump between the circulating water between the heat exchange chamber 2 of the first reactor 1001 and the second reactor 1002, so that the water temperature of the heat exchange chamber 2 of the two reactors is basically the same, and then turn on the circulation of the heat exchange chamber 2 The pum...

Embodiment 2

[0064] Example 2: see figure 2 , in this embodiment, include three reactors as reactors, i.e. the first reactor 1001, the second reactor 1002 and the third reactor 1003, it can be understood that the number of reactors can also be multiple, this Also within the protection scope of the present invention. The present invention utilizes a plurality of reactors to carry out corresponding heat exchange step by step. Each reactor has a steam compressor, which can evaporate water into steam as a heat transfer medium.

[0065] Step S1: Keep a certain water level in the heat exchange chamber 2 of each reactor (the first reactor 1001, the second reactor 1002, and the third reactor 1003), the sludge to be treated enters the first reactor 1001, and the third reactor Reactor 1003 is heated and stabilized to 120°. Open the pipeline between the heat exchange chamber 2 of the third reaction kettle 1003 and the heat exchange chamber 2 of the second reaction kettle 1002, so that the heat ex...

Embodiment 3

[0069] Embodiment 3: see image 3 , in this embodiment, include three reactors as reactors, i.e. the first reactor 1001, the second reactor 1002 and the third reactor 1003, it can be understood that the number of reactors can also be multiple, this Also within the protection scope of the present invention. The present invention utilizes a plurality of reactors to carry out corresponding heat exchange step by step. There is a steam compressor in each reaction kettle, and the steam compressor can be used to evaporate the liquid material to be treated into steam as a heat transfer medium.

[0070] Step S1: The sludge to be treated (normal temperature, 20°C) enters the stirring tank 1 of the first reaction kettle 1001. Use the heating device in the stirring tank 1 to heat the sludge to 120°, and turn on the stirring in the tank throughout the process to keep the sludge flowing efficiently sex.

[0071] Step S2: At the same time, the sludge to be treated (normal temperature, 20°...

Abstract

The invention discloses a heat exchange process and a treatment system for treating liquid substances. The process comprises more than two stages of reaction kettles; each reaction kettle is provided with an inner cavity and an outer cavity; liquid substances to be treated are positioned in the inner cavities or the outer cavities of the reaction kettles to be subjected to heating and / or cooling treatment, and the treated liquid substances to be treated are discharged from the reaction kettles; a heat exchange medium is arranged in the outer cavities of the reaction kettles; the heat exchange medium flows among the outer cavities of the multiple stages of reaction kettles, and the temperature difference and the requirement of different stages of reaction kettles in different treatment stages are utilized to finish the heating and / or cooling treatment of the liquid substances to be treated among the reaction kettles in a heat exchange form. The system is used for implementing the process. The process and system have the advantages of simple and compact structure, low cost, high treatment efficiency, good energy-saving effect, good application effect and the like.

Description

technical field [0001] The invention mainly relates to the technical field of processing technology for liquid substances, in particular to a heat exchange process and a processing system for processing liquid substances. Background technique [0002] Existing heat treatment reaction devices for liquid substances usually place the liquid substance to be treated in a tank, and then heat it to a certain temperature to complete the reaction under high temperature and high pressure, and then discharge it after pressure release and cooling. This type of device has the following problems: [0003] 1. Adopting single-reactor processing method, the energy consumption is very high, and the environmental protection is not good. [0004] 2. The liquid substance to be treated is in a static or micro-flow state. The liquid substance in this state cannot be heated evenly, and the heating rate is slow, which will greatly affect the evaporation efficiency; if the height or volume of the pr...
