The recycling of diluted waste acid produced in the production process of sulfate process titanium dioxide is a bottleneck limiting the development of the sulfate process titanium dioxide. In addition, manufacturers of sulfate process titanium dioxide usually have sulfate acid production devices due to the need of a large amount sulfate acid. The invention relates to a method and a device for producing concentrated sulfuric acid by recycling waste acid from sulfate process titanium dioxide production. The method comprises the following steps: firstly, performing the pre-concentration of the diluted sulfate acid; secondly, removing most impurities carried by the diluted sulfate acid through settlement; and finally, using the sulfate acid subjected to pre-concentration and impurity removal to replace make up water of a sulfate production system, adding the sulfate acid into a sulfate circulating tank of a sulfate acid absorption tower to produce concentrated sulfate acid after sulfate acid absorption tower absorbs sulfur trioxides, and thus recycling the diluted sulfate acid. The method has the advantages of making a plurality of achievements at one time, namely changing pre-concentrated diluted sulfate acid into concentrated sulfate acid without extra energy consumption and equipment addition while reducing the cooling load of sulfate acid flowing out from the tower at the sametime.

The invention relates to the technical field of indoor positioning, in particular to an indoor positioning method combining geomagnetic field and WIFI (wireless fidelity) signals. According to the method, in an offline sampling stage, WIFI signal strength and geomagnetic field information samples are simultaneously collected and are uploaded to a positioning center database, data characteristic fusion and analysis are performed by adopting a principal component analysis method at a positioning center to generate a fusion projection matrix, and all sampling information in the database are projected by the projection matrix to obtain a fusion sample; in an online positioning stage, the vector of WIFI and geomagnetic field intensity information received by a terminal is projected by the fusion projection matrix to generate a fusion vector, and a positioning result is obtained by comparing the fusion vector with the fusion sample in the positioning center database. By adopting the method, accurate positioning combining WIFI and geomagnetic field intensity information can be realized on an existing ordinary smart phone.

The speed-increasing gearbox adopts stepped speed change technology, reduces the energy loss of the power generation device, improves wind power generation device efficiency, saves investment, fully utilizes wind power resource and improves investment rate of return.

The invention relates to the technical field of humidifiers, in particular to a tape water humidifier for a heating radiator. The tape water humidifier comprises a box body, water soaking cloth, a water spraying device and a water tank. Two opposite sides of the box body are provided with openings, and the box body is arranged on the outer side of the heat radiator in a covering mode. The water soaking cloth shields the opening of one side, far away from a wall body, of the box body and is flush with a wall surface. The water spraying device is arranged in the box body so as to spray tap waterto the water soaking cloth. The water tank is arranged on a bottom plate of the box body and is located under the water soaking cloth. The water soaking cloth is arranged to change color when meetingwater.
