The invention relates to a river section structure for relieving urban land tension. The river section structure consists of a rectangular section, a water accessibility bank slope and a land territory control ground in sequence, wherein the rectangular section consists of a natural river bottom and a dry stone upright wall; the water accessibility bank slope consists of a water accessibility platform and an ecological side slope; the land territory control ground is positioned above the water accessibility bank slope. The river section structure is characterized in that the land territory control ground rises no less than a planned safe free board in the outward longitudinal direction, and the rise value is 0.5-1 meter. By designing the land territory control ground with the safe free board, the blue-line land territory control range can be fully utilized. By adopting a rectangular section structure on a main river channel, land is saved, the safety is ensured, and various functions of the river channel are not weakened, thereby eliminating the contradiction between urban land development and water.

The invention relates to a double-pressure dry quenching coke waste heat boiler. It consists of a flue gas system, a high-pressure drum, a high-pressure evaporator, a high-pressure economizer, a superheater and a water wall. The flue gas channel of the flue gas system is equipped with a low-pressure self-deoxygenation system at the outlet of the high-pressure economizer, and a low-pressure evaporator is installed on the low-pressure self-deoxygenation system. The rising pipe of the low-pressure evaporator is connected to the low-pressure drum, and a low-pressure economizer is installed under the low-pressure evaporator. The inlet of the low-pressure economizer is connected to the boiler water supply pipe, and the outlet is connected to the low-pressure drum through the outlet pipe. There is a bypass pipe between the inlet and outlet of the low-pressure economizer, and a circulating pump and a regulating valve are installed on the bypass pipe; a low-pressure evaporator is installed between the low-pressure evaporator and the downcomer of the low-pressure evaporator The inlet header, the outlet header of the low-pressure evaporator is arranged between the low-pressure evaporator and the rising pipe of the low-pressure evaporator. The invention effectively solves the problems of low thermal efficiency and the need to occupy a lot of land resources in the prior art.

The invention discloses a limestone screening device. The key points of its technical scheme are: it includes a lower material barrel, a first material conveying pipe, a dust conveying pipe and a material feeding device. The high end of the pipe is connected to the lower material barrel, the low end of the first feeding pipe is above the feeding device, the dust delivery pipe is installed on the side of the feeding pipe facing the ground, and the first feeding pipe faces the ground A plurality of filter holes are opened on the side wall of the first feeding pipe, and the plurality of filter holes are evenly distributed on the corresponding side wall of the first feeding pipe, and a dust collecting groove is arranged under the end of the dust sending pipe close to the ground. Most of the powder enters the dust delivery pipe through the filter holes, and then is collected by the dust delivery pipe and sent to the dust collection tank, so that the limestone powder can be recycled and the dust phenomenon of the limestone in the subsequent crushing process is alleviated. ; The dust delivery pipe is arranged obliquely together with the first material conveying pipe to reduce the land occupation in the horizontal direction.

The invention provides a system and a method for storing high-pressure gas in the seabed. The gas is continuously compressed into a sealed gas tank arranged on the seabed through a gas inlet pipe by virtue of a gas compressor; when the high-pressure gas in the sealed gas tank needs to be used, the high-pressure gas is released to an external energy conversion device through a gas outlet pipe by the sealed gas tank; the pressure value is transferred to a controller by internal and external sensors to perform pressure comparison so as to control a lifting device; when pouring the high-pressure gas into the sealed gas tank, the lifting device drives the sealed gas tank to sink downwards; when the sealed gas tank releases the high-pressure gas outwards, the lifting device drives the sealed gas tank to float upwards; and when the sealed gas tank stores the high-pressure gas or discharges the high-pressure gas, the internal and external pressure difference borne by a shell of the sealed gas tank is within the pressure range which can be borne by the shell of the sealed gas tank, that is, high-pressure gas can be poured into the sealed gas tank without the supporting of a thicker tank wall, and the manufacture cost of the sealed gas tank is low.

The invention relates to a method for preparing a baking-free brick from waste drilling slurry. The baking-free brick is prepared from the following raw material components: drilling cuttings, a cementing agent, an activity excitation agent, a retarder, a reinforcing agent, a pollutant controlling agent, other auxiliary agents and water. A preparation process comprises the following steps: sufficiently mixing the components according to a certain sequence and a certain ratio; after ageing, preparing a clinker; adding the cementing agent and the water into the clinker for the second time and carrying out wheel grinding again; putting the mixture into a steel mold and molding; de-molding to obtain a brick blank; after curing the brick blank, stacking; finally, naturally drying to obtain a finished product. The baking-free brick prepared by the method has relatively high compression strength and bending strength and all indexes of leachate reach Standard for Pollution Control of General Industrial Solid Waste Storage and Disposal Sites (GB18599-2001); the cost is relatively low.
