The invention relates to a special-purpose solid cleaning agent of a dish-washing machine and a preparation method thereof. The special-purpose solid cleaning agent consists of the following substances in percent by weight: 20%-50% of sodium hydroxide or / and potassium hydroxide, 15%-30% of sodium carbonate, 10%-20% of sodium metasilicate, 3%-6% of sodium dichloro isocyanurate or imidazolidinedione, 4%-8% of EDTA (Ethylene Diamine Tetraacetic Acid), 1%-5% of sodium citrate, 5%-10% of a dispersing agent PAA (Poly Acrylic Acid), 1%-5% of borax and the balance of water. The preparation method of the special-purpose solid cleaning agent comprises the following steps of preparing the solid substances according to a proportion of the formula; starting up a reaction kettle, and respectively adding the solid materials under stirring; adding water after all solid materials are added and uniformly stirred; starting to heat up inside the reaction kettle with the addition of water, so that the materials generate reaction; stirring reactants for cooling to 50 DEG C-60DEG C, and starting to discharge; metering and pouring moving materials to a product container when the moving materials are hot, cooling and forming to obtain a finished product. The preparation method disclosed by the invention is low in reaction temperature, good in reactant mobility, easy for finally forming, energy-saving, environment-friendly and high in efficiency.

The invention provides an automatic control efficient multi-oxygen combustion ultra-low emission industrial kiln. The industrial kiln is provided with a kiln hole, a kiln vehicle, kiln vehicle operation tracks and driving mechanisms. The kiln hole is in an approximate prism shape and provided a first branch hole and a second branch hole, a first connection hole and a second connection hole are formed, and the kiln vehicle operation tracks which communicate mutually and the driving mechanisms are arranged in the branch holes and the connection holes correspondingly. A preheating zone, a firingzone and a cooling zone are sequentially arranged in the first branch hole. A blank feeding zone 7, a drying zone 2 and a separation zone 8 are arranged in the second branch hole. A first kiln vehicletrack transfer mechanism is arranged in the first connection hole, a second kiln vehicle track transfer mechanism is arranged in the second connection hole, a first induced draft fan and a second induced draft fan are further arranged, and a fuel gas pipe, a fuel gas spray head, a combustion-supporting gas pipe, a combustion-supporting gas spray head and an igniter are arranged in the firing zone. Compared with a conventional combustion method, flue gas emission is reduced by 70% or more, flue gas basically contains no nitric oxide, energy consumption is reduced, the heat utilization rate ishigh, the heating firing efficiency and the product production efficiency are improved, the energy conservation and environment protection effect is good, gas fuel consumption is reduced, the purposesof energy conservation and environment protection are achieved, automatic control is flexible, and the operation cost is greatly reduced.
