This invention discloses an ammonium sulfate wastewater treatment system and method, comprising an ammonium sulfate wastewater storage tank for collecting ammonium sulfate wastewater; a calcium hydroxide preparation system for preparing calcium hydroxide solution; an evaporator and a first circulating heater for reacting and evaporating the ammonium sulfate wastewater and calcium hydroxide; a first crystallizer and a second circulating heater, a second crystallizer, and a third circulating heater for two-stage evaporation and crystallization; the final concentrated liquid is filtered and flows into a mother liquor collection tank for convenient wastewater treatment, while the evaporated ammonia gas is absorbed by a cooling absorption tower and a condensate collection tank to form ammonia water; the condensate from the second heat exchanger, the first circulating heater, the second circulating heater, and the third circulating heater is also returned to the condensate collection tank. This wastewater treatment system and method distill and crystallizes ammonium sulfate wastewater with calcium hydroxide solution, thereby recovering calcium sulfate and ammonia water, thus achieving waste utilization.

This utility model discloses an automatic centering and tensioning clamp and a product processing system, relating to the field of clamping technology. The automatic centering and tensioning clamp includes a fixed base with an adjusting plate hinged to it. A first driving assembly is mounted on the adjusting plate, and the power output end of the first driving assembly is connected to an adapter. A product base is mounted on one side of the adapter, and a positioning post is mounted on the product base. The positioning post has a first mounting hole and a second mounting hole. A driving component is located in the first mounting hole, and a positioning block is located in the second mounting hole. A second driving assembly is located between the adapter and the product base. The power output end of the second driving assembly drives the driving component, which in turn drives the positioning block. After extending out of the second mounting hole, the positioning block can tension and fix the product sleeved on the positioning post. This utility model can solve the problem of ineffective positioning and clamping of ring-shaped / tube-shaped products.

The utility model discloses a low-energy-consumption coal-fired flue gas denitration reactor and relates to the technical field of waste gas treatment. The flue gas treatment device comprises a treatment pipe, a flue gas pipe is fixedly connected to the surface of the treatment pipe in an inserted mode, a filter screen is fixedly connected to the inner wall of the flue gas pipe, a reverse blowing assembly used for cleaning the filter screen is arranged below the filter screen, and an impurity removal assembly used for absorbing impurities is arranged at the top of the treatment pipe. A purification box is fixedly connected to the bottom of the treatment pipe, two ceramic filter elements are installed in the purification box, a sealing door is hinged to the front face of the purification box, an SCR denitration device is fixedly installed at the bottom of the purification box, and an exhaust pipe is fixedly connected to the surface of the SCR denitration device in an inserted mode; the coal-fired flue gas filtering device has the advantages that the coal-fired flue gas can be automatically filtered during use, the filter screen can be automatically and effectively cleaned, blockage of the filter screen due to long-time operation is avoided, and the coal-fired flue gas filtering device is more convenient to operate and maintain.
