The invention discloses a technology for preparing low-carbon alcohol from syngas and coke oven gas. The technology comprises the following steps: mixing coke oven gas and syngas to form crude raw material gas for low-carbon alcohol synthesis; washing the crude raw material gas by low temperature methanol to remove the impurities such as hydrogen sulfide, carbon dioxide, and the like to produce purified gas for low-carbon alcohol synthesis, recycling the removed hydrogen sulfide after the sulfur is removed, discharging carbon dioxide into the sky; subjecting the purified gas to low-carbon alcohol synthesis, separating the synthesis products, which are in a gas phase and a liquid phase, to obtain a gas product, which is mainly composed of CO, H2 and CO2, and a liquid product, which is a mixture of alcohol and water, subjecting the gas product to the low temperature methanol washing and circulation, combusting the other part of gas product in a torch as exhausted gas or discharging the gas product; and separating the alcohol from the liquid product so as to obtain the low-carbon alcohol product. The technology can obtain a plurality of products, can reduce the excessive production capacity, promote the energy saving and discharge reducing, and adjust the energy structure.

The invention discloses a ground torch system. The ground torch system comprises a plurality of ground combustors and an anti-radiation fence; the plurality of ground combustors are arranged in at least two rows, and the number of the ground combustors in each row is at least two; the anti-radiation fence is arranged on the outer sides of the ground combustors in a surrounding mode, wherein the distance between two adjacent rows of ground combustors is at least 6 meters, and the distance between two adjacent rows of ground combustors in each row is at most 2 meters. Therefore, by limiting thedistance between every two adjacent rows of ground combustors and the distance between every two adjacent ground combustors in each row, the positions of the ground combustors can be arranged more reasonably, and when the ground torch system treats large-displacement combustible gas, the ground combustors can receive sufficient air; the phenomena of insufficient combustion, smoking and the like ofthe ground combustors during gas combustion can be avoided, and pollution to the environment is reduced.

The invention discloses a processing system for renovating the inner wall of a vertical steel drum which has the advantages of simple and reasonable structure, high stability and low cost. The end of a spray rod is connected with a torch firing device and a brushing head; the spray rod is connected with a spray rod rotating motor and an elevation driving mechanism through a transmission mechanism; a main frame is provided with a clamping apparatus in the corresponding position of the spray rod; the clamping apparatus is connected with a drum rotating motor through the transmission mechanism; the main frame is provided with a drum bracket; a drum support plate elevation driving mechanism is arranged on the drum bracket; and a drum support plate is connected with the drum support plate elevation driving mechanism. The processing system for renovating the inner wall of the vertical steel drum of the invention improves the elevation and displacement structure and reasonably combines the components, thereby simplifying the equipment structure, enhancing the stability, reducing the cost and lowering the difficulty in equipment manufacture. In addition, the torch firing and the brushing are carried out on the same station, thereby further simplifying the equipment structure.

The invention provides a torch component of a plastic rolling machine. The torch component comprises a nozzle and a gas tube. The nozzle is provided with an injection portion and a connection portion, a nozzle orifice is arranged at one end of the injection portion, the other end of the injection portion is communicated with the connection portion, the injection portion is provided with an injection passage along the axial direction of the injection portion and is communicated with the gas tube through the connection portion, a necking portion is disposed in the injection passage, and the diameter of the injection passage is increased gradually from the necking portion to the connection portion, and is particularly increased first and then reduced from the necking portion to the nozzle orifice. When flowing through the injection passage, natural gas can be compressed by the necking portion, and flow rate of the natural gas is increased, so that flame injection speed is increased, heating efficiency to moulds is increased, and quality of plastic rolled products is improved.
