A composite consolidated soil pavement base material and its construction method, the material is composed of the following components by weight percentage: 92-98% of sandy soil, 2-8% of cement, ZL-1 containing 85% of sulfonic acid Or EN-1 liquid curing agent is 0.1-0.3‰ of the total lime-soil mixture; or ZL-1 with 90-96% silty soil or clay soil, 4-10% lime, and 85% sulfonic acid EN-1 liquid curing agent, 0.1-0.3‰ of the total amount of lime-soil mixture. The material and construction method of this kind of composite consolidated soil pavement base uses widely distributed soil as the main material, which can use local materials, reduce the construction cost by 20-50%, have early strength, shorten the construction period, and resist frost. Areas can extend the effective construction period.

The invention discloses a sunlight-accumulating garbage incineration device which is suitable for being applied to a small range of urban areas and achieves processing of intraday garbage cleanly and timely. The sunlight-accumulating garbage incineration device is composed of a squeeze propeller, a feeding helix, a heated body assembly, a focus lamp array, a seat frame, a boiler and a power distribution box, wherein the squeeze propeller, the feeding helix, the heated body assembly, the focus lamp array, the seat frame, the boiler and the power distribution box are connected on a public machine seat. The sunlight-accumulating garbage incineration device is characterized in that a discharge end of the squeeze propeller is connected with the feeding helix, the feeding helix and the front end of a feeding channel are sleeved inside the feeding channel of the heated body assembly coaxially, the feeding helix and the front end of the feeding channel are communicated with and fixedly connected with a discharge port of the squeeze propeller, the other ends of the feeding helix and feeding channel are communicated with and fixedly connected with a feeding port of the a combustion chamber, a left heat exhaust channel, a right heat exhaust channel and an electric heating channel are coaxially arranged on the same wall of the lower portion of the feeding channel of the heated body assembly, wherein the electric heating channel is arranged in the middle. Two channels arranged at the front end of the heated body assembly of the heat exhaust channel are communicated with each other, a channel in the other end of the heat exhaust channel is communicated with and fixedly connected with a combustion chamber of the boiler through a guide pipeline, the other channel of the heat exhaust channel is communicated with and fixedly connected with a chimney of the boiler, the convex lens focus point of the focus lens array is arranged on the external top face of the feeding channel, and the sunlight-accumulating garbage incineration device is simple in structure and low in investment.

The invention relates to a process and a device for quickly preparing powdered active coke for desulfurization by utilizing pulverized coal. The process and the device are used for producing a powdered active coke product with certain desulfurization performance and reducing combustible gas. According to the process, the powdered active coke for desulfurization and a byproduct reducing gas are prepared from the pulverized coal of 20 to 500 microns by remaining in an entrained-flow bed fast reaction furnace for 1 to 60 seconds. The process and the device has three characteristics that 1, the desulfurization active coke can be prepared by directly utilizing the pulverized coal for combustion of a boiler, so in-situ preparation of a desulfurizing agent of a coal-fired power plant can be realized, and the production cost and the transportation cost of the active coke are reduced; 2, the reducing combustible gas generated in the production process of the active coke can serve as a reburning fuel and is fed into the boiler, so the production quantity of nitric oxide during combustion of the pulverized coal is reduced and the energy efficiency of the whole process is improved; and 3, sulfur dioxide can be recovered and high-concentration sulfur dioxide can be reduced into elemental sulfur, so resource utilization of the sulfur dioxide can be realized.
