Description
Technical Field
The invention belongs to the technical field of coal pyrolysis equipment, and particularly relates to a positioning piece for a bottom hole of a filter element of a high-temperature filter.
Background
Filters with internal temperatures greater than 300 ℃ are commonly referred to as high temperature filters. In the field of coal pyrolysis, the temperature of coal gas discharged from pyrolysis equipment is more than 300 ℃, the coal gas contains a large amount of coal tar and coal dust, the coal dust and the coal tar must be separated at a high temperature state first to obtain relatively pure coal tar, and because the temperature is relatively high, a filtered filter body usually adopts a high-temperature resistant ceramic filter element or a powder metallurgy type metal filter element.
In the working engineering of the filter, because the temperature is higher, the filter element bears the alternating load caused by back flushing, the two filter element materials have larger brittleness, and the filter element is more easily subjected to brittle fracture in a non-vertical state, therefore, the filter element in the high-temperature filter needs a righting measure, the righting adopts the positioning of the upper end and the lower end of the filter element, wherein the bottom hole of the filter element is righted by a flat-headed pin, but the phenomenon that the filter element fractures in a large scale is found in the using process, the fracture of the filter element is confirmed to be related to the filling of the reserved gap of expansion with heat and contraction with cold after analysis, namely, the gap between the end surface of the bottom hole of the filter element and the top surface of the flat-headed pin is filled with the lifted coal powder, so that the required compensation of the expansion with cold and contraction with cold is not existed, the filter element is broken, and the fundamental reason is that once the top surface of the flat-headed pin enters the coal powder, the coal powder is difficult to fall off by itself, and the larger the accumulation is increased until the reserved gap is basically filled.
Therefore, need develop a new device that is applicable to high temperature filter core bottom outlet location, can realize on the one hand that the filter core is fixed and right in the filter, on the other hand can avoid in the course of the work flat head round pin top surface to save the coal dust and lead to filter core to appear big batch fracture phenomenon.
The invention patent with the granted publication number of CN 105126490B provides a high-temperature resistant filter, which mainly comprises a filter upper cover, a filter lower cover, a supporting filter frame and a filter element, wherein the filter element is connected with the filter upper cover in a positioning way through the supporting filter frame, the filter upper cover is provided with an air inlet interface and an air outlet interface, the filter lower cover is sleeved outside the filter element, the high-temperature resistant filter also comprises a sealing end cover, the bottom of the filter lower cover is sleeved on the sealing end cover, the upper part of the sealing end cover is connected with the bottom of the supporting filter frame through threads, the bottom of the filter lower cover is positioned between the sealing end cover and the supporting filter frame, and the top of the filter lower cover and the filter upper cover are positioned and pressed tightly; the air inlet interface of the upper cover of the filter is communicated with the inner cavity of the filter element, and the air outlet interface is communicated with the outer cavity of the filter element. The turbid flue gas enters the filter element through the air inlet interface of the filter and the rectangular air guide groove in the support filter frame, then flows out of the filter element, and finally enters the instrument through the air outlet interface of the filter. The filter can replace the filter element without tools in the use process, and meanwhile, the thread part of the filter does not need to be wound with a flexible sealing piece. However, the filter element in the filter still adopts the flat-head pin to realize the bottom positioning, which is easy to cause the phenomenon of mass breakage of the filter element.
The invention patent with application publication number CN 107024071A discloses a filter element positioning device for a refrigerator filter, which comprises a shell, an upper pressing plate, a lower pressing plate, a base and a partition plate, wherein the upper pressing plate and the lower pressing plate are respectively fixed on the upper side and the lower side in the shell, the upper pressing plate is provided with a through hole close to the middle, the partition plate is fixed between the upper end of the upper pressing plate and the shell, the lower end of the partition plate is fixed at the edge of the through hole, the base is fixed at the lower end in the shell, the lower pressing plate is fixed at the upper end of the base, the upper pressing plate is connected with the side wall of the shell through a tension spring, and the side wall of the shell is provided with a turnover cover. Compared with the prior art, the filter element positioning device for the refrigerator filter has the following advantages: can play the positioning action to the filter core, can conveniently change the filter core, reduce cost of maintenance. However, the invention belongs to the positioning of a low-temperature filter cartridge filter element, and is not suitable for filtering high-temperature dust generated in the coal pyrolysis process.
