specific Embodiment approach 1
[0015] Specific implementation mode one: the method for mixing flocculant and motor vehicle cleaning sludge in this embodiment is carried out according to the following steps:
[0016] 1. Atomization of flocculant:
[0017] The liquid flocculant is atomized into mist flocculant by ultrasonic atomizer;
[0018] For the solid flocculant, first dissolve it with clean water into a liquid aqueous solution, and then use an ultrasonic atomizer to atomize it into a mist flocculant;
[0019] 2. Mixing of mist flocculant and air: place the spray port of the ultrasonic atomizer in a static mixer connected to the atmosphere, and mix the mist flocculant with air under normal pressure to obtain mist flocculant and air mixture;
[0020] 3. Mix the mixture obtained in step 2 with the water-containing car washing sludge by using a gas-liquid mixing pump under pressure.
[0021] Compared with the stirring mixing in the traditional flocculation tank, this method mixes the flocculant and car w...
specific Embodiment approach 2
[0022] Embodiment 2: This embodiment differs from Embodiment 1 in that: in step 1, the ultrasonic frequency of the ultrasonic nebulizer is 30-50 kHz. Others are the same as in the first embodiment.
specific Embodiment approach 3
[0023] Embodiment 3: This embodiment differs from Embodiment 1 or Embodiment 2 in that: in step 1, the ultrasonic frequency of the ultrasonic nebulizer is 40 kHz. Others are the same as in the first or second embodiment.
