The invention discloses a method and a device for measuring the wall adhering quantity of sludge. The device comprises a constant-temperature tank, a sludge measurement barrel, an electronic scale and a computer, wherein the computer is connected with the electronic scale; and the sludge measurement barrel is placed in the constant-temperature tank which is placed on the electronic scale. The wall adhering quantity of sludge is measured through the gravity of the sludge per se, the electronic scale weighs the masses of the constant-temperature tank, a constant-temperature support, the sludge measurement barrel and a lower cover at first, and then weighs the mass of the sludge measurement barrel into which sludge is placed, after the constant-temperature tank rises to a certain temperature, the lower cover is opened to enable the sludge to fall to a sludge receiving plate, the electronic scale weighs the mass of the rest, and then the wall adhering quantity of the sludge is obtained through gravimetric method. According to the invention, the wall adhering quantity of the sludge is measured according to the gravity of sludge per se, so that system errors caused by human factors are reduced.
Description
technical field [0001] The invention relates to the field of sludge measurement, in particular to a method and device for measuring the amount of sludge sticking to walls. Background technique [0002] After the sludge is dried, it can not only significantly reduce the volume, but also significantly reduce the negative characteristics such as odor, pathogenic bacteria, and viscosity. The dried sludge has many uses. However, in the process of thermal drying of sludge, the phenomenon that sludge sticks to the surface of thermal drying equipment often occurs, that is, sludge sticks to the wall. Due to the sludge sticking to the wall, one is to reduce the efficiency of heat transfer during the sludge drying process, hinder the evaporation of water in the sludge, and reduce the drying speed of the sludge, resulting in a waste of energy; The wall sticking leads to equipment corrosion and affects the service life of the drying equipment; thirdly, in order to solve the wall stickin...
