Problems solved by technology

[0003] Chinese patent CN113144728A discloses an automatic high-temperature wastewater treatment equipment, which integrates cooling components and sewage treatment components, so that water inflow, water outflow, and temperature drop can be carried out simultaneously, and the separation effect of flocculation is good, but only a single The single-stage cooling system has a slow heat transfer rate, which leads to a slow cooling rate of high-temperature sewage, and in the process of cooling high-temperature sewage, there is no clear cooling target and corresponding adjustment procedures, resulting in limited heat absorption of high-temperature sewage by the single-stage cooling system , so that a large amount of heat in high-temperature sewage cannot be completely absorbed and is wasted, thus affecting the waste heat recovery speed and waste heat recovery efficiency of high-temperature sewage

Embodiment 1

[0033] A high-temperature sewage closed cooling and whitening equipment with waste heat recovery, such as figure 1 As shown, it includes a drain pipe, a water collector, a sewage pump, a steel ball filter unit, a primary heat exchanger, a secondary heat exchanger and a sewage well; In the water collector, the water collector has the characteristics of heat preservation to prevent temperature loss and carrying high pressure. The water collector is equipped with a pressure sensor to effectively monitor the internal pressure and provide a start signal for the sewage pump, which pumps the high-temperature sewage in the water collector. It is filtered in a recyclable steel ball filter unit, and the filtered sewage enters one side of the primary heat exchanger through the pipeline for primary heat exchange work. Cooling water and high-temperature sewage conduct first-stage heat exchange. One end of the first-stage heat exchanger is fed with softened water of 10°C-25°C on the opposit...

Embodiment 2

[0036] This embodiment is further optimized on the basis of Embodiment 1, such as Figure 2-Figure 9 As shown, the steel ball filter unit includes a mounting bracket 1, a filter cabin 2, an infusion pipe 3, a liquid inlet pipe 4, a liquid outlet pipe 5, an annular pipe 51, a sewage pipe 6, a filter cartridge 7, a filter steel ball, and a middle isolation plate. 9 and conical plug 10; several filter cabins 2 are connected with bolts on the mounting bracket 1; the infusion pipe 3 is flanged between the liquid inlet valves 21 of the filter cabin 2; the water pump flange is connected to the liquid inlet of the infusion pipe 3; The liquid inlet pipe 4 is installed on the upper part of the left side of the installation bracket 1; the left side of all the filter cabins 2 are connected to the liquid inlet pipe 4 through the pipe flange, and the filter screen 24 is installed on the left outlet of the filter cabin 2; the right side of the installation bracket 1 is installed. A liquid ou...

Abstract

The invention relates to the field of sewage treatment, in particular to high-temperature sewage closed cooling and white-eliminating equipment with a waste heat recovery function. The technical problems that waste gas pollution is caused when high-temperature process sewage is discharged in an unorganized mode, and no clear cooling target and no corresponding adjusting program exist in waste heat recycling are solved. The high-temperature sewage closed-type cooling and white-eliminating equipment with the waste heat recovery function comprises a process high-temperature sewage closed-type discharge water collector, a steel ball filter unit, a heat exchange unit and the like. The multi-stage cooling system is arranged, each stage of cooling system is provided with a specified cooling target and a corresponding adjusting program, the high-temperature sewage waste heat recovery efficiency is improved while the high-temperature sewage cooling speed is increased, it is guaranteed that the whole process from a source to discharge is closed and does not make contact with the atmosphere, white pollution is eliminated, and the environment protection effect is achieved. When the heat exchange temperature is detected to be excessive or insufficient, the water pump adjusts the flow speed of the cooling liquid in a variable-frequency mode, and the heat exchange efficiency is improved.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a closed-type cooling and whitening device for high-temperature sewage with waste heat recovery. Background technique [0002] The treatment of sewage is generally cumbersome, especially in the treatment of high-temperature sewage. The temperature of the sewage that has just flowed out from the drain pipe of the dyeing tank is much higher than the boiling point of pure water. The first is to avoid the unorganized discharge of waste steam, the second is to adapt to the living conditions of the biochemical flora of sewage treatment, and the third is to realize waste heat reuse at the same time. [0003] Chinese patent CN113144728A discloses an automatic high-temperature wastewater treatment equipment. The equipment is integrated with cooling components and sewage treatment components, so that water inlet, water outlet, and cooling can be carried out simultaneously, and the separatio...
