Description
Technical Field
The invention relates to the field of coke oven construction, in particular to a heat recovery coke oven front surface line error control method.
Background
Conventional vertical coke ovens for the recovery of chemical products have been used for over 100 years with great technical and economic success. However, with the increasingly wide popularization and use of the chemical production coke oven, the coke oven encounters difficulties in the aspects of environmental protection, comprehensive utilization of coal resources and the like. In order to make the coking industry healthily developed, clean heat recovery coke ovens have come into force. The heat recovery coke oven has the advantages of good coke quality, less environmental pollution, capability of utilizing more weakly caking coal and non-caking coal and the like.
However, the heat recovery coke oven is a novel coke oven, construction experience at home and abroad is relatively less, a complete set of construction technology and method is not formed, however, the masonry quality of the coke oven masonry in the coke oven engineering is the greatest importance for the heat recovery coke oven, the service life of the coke oven is determined, and the masonry quality of the masonry can be used for installing the oven protection iron pieces.
The main stream of the masonry method for controlling the error of the front face line of the coke oven is to lay a layer by taking two front face lines as a reference on a base bottom plate of the coke oven at first, and each layer is level with the masonry boundary of the lower layer. Each layer of masonry is built by coke side to machine side. Because the machine side is the material loading side, build by laying bricks or stones to the machine side from burnt side can reduce and go up the brick personnel to build the trampling of brickwork by laying bricks or stones on the same day to cause quality problems. However, this method has a drawback that the boundary between the upper and lower bricks is easily accumulated as a laying alignment line, which causes deviation of the face line. Secondly, the inspection is inconvenient, a long ruler of 50m needs to be pulled towards the normal line from the center line for inspection during each inspection, each hole of each layer needs to be inspected and accepted, the long ruler is used for inspection for 42 times at least for each layer, a large amount of time is wasted, and data errors are easy to generate. Thirdly, the masonry from one side to the other side is manually operated, and the plus-minus tolerance influence of bricks and the error of brick joints easily cause the error of a plus line when the masonry is carried out to the other side.
The known coke oven face line control methods therefore suffer from the various inconveniences and problems described above.
