The invention belongs to the technical field of superheated steam coal upgrading for semiconductor temperature difference power generation, in particular to a thermal compensation type superheated steam coal upgrading system for power generation with temperature difference. After the raw coal is crushed and screened by the coal crusher, it enters the superheated steam fluidized bed through the coal bunker, flows out from the bottom of the fluidized bed after heat and mass transfer occurs, and becomes upgraded coal after passing through the coal cooler; the superheated steam source comes from electric superheating The steam generator and superheated steam extract air, and the heat source of waste heat exchanger and solar heat exchanger performs thermal compensation for the production of superheated steam; the moisture contained in raw coal is heated and evaporated in the fluidized bed, and mixed with superheated steam into two Secondary steam, after passing through the circulating fan, enters the secondary steam heat exchanger tube group, heat exchange with the raw coal again, and condenses into precipitated water; the flue gas and sewage waste heat source, solar heat source and circulating superheated steam are used as high-temperature power for thermoelectric power generation The side heat source, the cooling water and the precipitated water after passing through the buried pipe group in the coal bunker are used as the low-temperature side cold source for thermoelectric power generation.

The invention discloses a tappet comprehensive gauge. A rotating disc is horizontally arranged above a bottom plate, and a clamping plate and a V-type block are arranged above the rotating disc, wherein the V-type block is fixed with the top surface of the rotating disc, and an opening of the V-type block faces the clamping plate. Two ends of the clamping plate are respectively fixed with corresponding portions of the opening end of the V-type block, and a clamping region is formed between the clamping plate and the opening of the V-type block. A dial indicator is vertically arranged above the V-type block, and the head of the dial indicator faces the clamping region. A straight line sliding platform is located besides the rotating disc, a sliding rail of the straight line sliding platform is fixed with the top surface of the bottom plate, a meter seat is fixed on the sliding platform top surface of the straight line sliding platform through a connection plate, and the lever dial indicator is installed at an installment end of the meter seat. The tappet comprehensive gauge is a comprehensive gauge which is simple and easy to use, has tappet top surface radial beating degree inspection and surface profile inspection functions, is high in inspection precision, convenient to inspect, low in requirements for use environment, and accordingly can be used for temporary inspection on the spot.

The patent of the present invention proposes an extrapolation method for first arrival waves of seismic data. Firstly, a time window is set around the first arrival wave of the shot set; secondly, the wave fields of the reference trace and the target trace are deconvoluted and superimposed in the shot domain to form a virtual wave field; thirdly, the wave field of the reference trace and the virtual wave field are combined The field is convolved and superimposed in the detector point domain to obtain the super virtual first arrival wave; from the second time, it is judged whether to use cyclic iteration; in addition, the first arrival wave is extrapolated, and the target trace is located between the detector arrays of the target shot set Then, deconvolution stacking and convolution stacking are performed in the shot domain and receiver point domain in turn to obtain the extrapolated super virtual first arrival wave; after that, it is judged whether to use cyclic iteration. The invention can effectively enhance the energy of the first arrival wave, improve the signal-to-noise ratio of the first arrival wave, and at the same time greatly increase the amount of available first arrival wave data through extrapolation of the first arrival wave, provide more abundant information for subsequent seismic data processing, and can be well It is used for seismic data acquired under complex near-surface conditions.

The invention discloses an active inclined single-row pile foundation pit support method. The following steps are adopted: 1) driving support piles inclined into the pit along the inner side of the edge of the foundation pit to the design elevation of the pile bottom to form a single-row support 2) Set a jack on the pile top of each supporting pile; 3) Set a crown beam on the single row of supporting piles, and use the crown beam to connect all The support piles are connected as a whole; 4) Excavate the soil surrounded by a single row of support piles to the design elevation of the pit bottom, and use the jack set in step 2) to apply pressure to the support piles Control expansion force to reduce soil and pile top displacement. The invention uses the jack to actively control the displacement of the inclined single-row piles, which can greatly reduce the displacement of the pile top, reduce the bending moment of the pile body, reduce the engineering cost, increase the excavation depth, and reduce the risk of overturning damage in the foundation pit. possibility.

The invention discloses an active bidirectional inclined pile row foundation pit supporting method. The method comprises the following steps that (1) inward-inclined supporting piles inclined towardsthe interior of a pit and outward-inclined supporting piles inclined towards the outer portion of the pit are driven to the pile bottom design elevation in a staggered manner along the inner side of afoundation pit edge, and meanwhile a waterproof curtain is arranged behind the outward-inclined supporting piles; (2) a jack is arranged at the pile top of each inward-inclined supporting pile; (3) acrown beam for connecting all the inward-inclined supporting piles and all the outward-inclined supporting piles into a whole is arranged on a bidirectional inclined pile row formed by all the inward-inclined supporting piles and all the outward-inclined supporting piles; and (4) the soil defined by the inward-inclined supporting piles is excavated to the pit bottom design elevation, and in the excavation process or before excavation, the jacks arranged in the step (2) are adopted for applying control expansion force to the inward-inclined supporting piles so as to reduce displacement of thesoil and the pile tops. By means of the method, the pile top displacement can be reduced to a large degree, the bending moment of pile bodies and the engineering cost can be reduced, the excavation depth can be increased, and the possibility of toppling damage happening to the foundation pit can be reduced.
