Unmanned vehicle to carry out an animal-related action, provided with a frame and a control device to control the vehicle and a locomotion device to move the unmanned vehicle, and with a protective device to protect the vehicle against obstacles, wherein the protective device includes a touchable electrical conductor which extends on the outside of, advantageously around, the vehicle, and a voltage source to supply voltage to the conductor under the control of the control device.

The present disclosure provides methods and systems of a modular coal liquefaction system. A modular coal liquefaction system may include a reactor for exposing a coal to a hydrogenated vegetable oil in the presence of a coal-derived solvent to form a slurry, a heater that elevates the temperature of the slurry in the reactor to facilitate liquefying the coal and liberating a volatile matter, and a centrifuge that separates the insoluble components from the slurry to obtain a de-ashed coal extract, wherein the coal extract is suitable for downstream processing, wherein the reactor, heater, and centrifuge are adapted to be modular. The system may further include a distillation column that distills the de-ashed coal extract to obtain a pitch. The system may further include a coker that cokes at least one of the de-ashed coal extract and the pitch to obtain a coke. The system may be adapted to be modularly disposed on a rail car. The system may be adapted to be modularly disposed on a semi-truck trailer.

The invention discloses a coking waste gas purification system, which belongs to the field of energy saving and environment protection of the coking industry. The coking waste gas purification systemcomprises a coking smoke generating and processing system, a dry quenching system and a tank nitrogen sealing system, wherein the coking smoke generating and processing system comprises a coke oven, acoke oven horizontal flue and a coke oven smoke desulfurization and denitrification device; the dry quenching system comprises a dry quenching furnace; the tank nitrogen sealing system comprises a chemical product storage device; the dry quenching furnace is provided with a circulating inert gas outlet and a circulating inert gas inlet; each tank of the tank nitrogen sealing system is respectively provided with a chemical product tank gas inlet used for introducing nitrogen, and a chemical product tank gas outlet used for emitting chemical product tail gas; the circulating inert gas outlet ofthe dry quenching furnace is connected with three gas pipelines, wherein one gas pipeline is connected with the circulating inert gas inlet of the dry quenching furnace for importing circulating inert gas to cool cokes in the dry quenching furnace, another gas pipeline is connected with the chemical product tank gas outlet of the chemical product storage device for importing into spreading tail gas blow gas pipeline of the circulating inert gas, and the final gas pipeline is connected with an in-furnace gas inlet arranged on the coke oven for importing the spreading tail gas dilution coke oven combustion chamber gas of the circulating inert gas. According to the coking waste gas purification system, coking chemical product tail gas can be fully recovered and utilized, and tail gas waste heat can be effectively recovered.
