The invention discloses a reverse osmosis concentrated seawater processing system and a method. According to the method, the reverse osmosis concentrated seawater processing system is adopted; reverse osmosis concentrated seawater is delivered through a security filter successively for filtering, pH value is adjusted, pressure is increased, and obtained pretreated water is delivered through a nanofiltration membrane element, a resin softening device, and a heating tank so as to obtain a heat material liquid; the heat material liquid is delivered through a membrane distillation element so as to obtain fresh water and a concentrated material liquid; the concentrated material liquid is subjected to treatment via bipolar membrane electrodialysis so as to obtain an acidic solution and an alkali solution. The method is high in softening efficiency; membrane distillation operation temperature is low; evaporation area is large; the quality of obtained fresh water is high; internal recovering of steam latent heat is realized; influence of concentration on membrane distillation is low, so that deep condensation is capable of obtaining the concentrated material liquid beneficial for high efficiency operation of bipolar membrane electrodialysis, the value of the obtained acidic solution and the alkali solution is higher than that of solid salt. Compared with the prior art, the method possesses following advantages: energy is saved; the production process is safer, and is more friendly to the environment; the obtained acid and alkali can be used for nanofiltration scale inhibition and resin regeneration, so that the adding amount of chemical agents of the whole system is reduced, and cost is reduced.

The invention discloses a waste tire crusher. The comprises a box body, wherein a partition plate, a heating cavity arranged above the partition plate and a crushing cavity arranged below the partition plate are arranged in the box body, the heating cavity is internally provided with a heating mechanism, and the crushing cavity is internally provided with a crushing mechanism. According to the waste tire crusher, the partition plate is arranged, the box body is divided into the upper cavity and the lower cavity which are independent, and the two cavities can work independently and can also cooperate with each other for running, so that the working efficiency is improved; the heating mechanism is used for heating waste tires to a softening degree without melting, and the crushing mechanismis used for crushing and cutting the waste tires, so that the follow-up utilization of the waste tires is facilitated; and due to the adoption of the structure, the softened waste tires can enter thecrushing mechanism to be crushed in a mode of being more labor-saving and efficient, and the crushing efficiency of the waste tires is greatly improved.
