Abstract
The utility model discloses a dimethoxymethane gas-liquid separation buffer for production of polyformaldehyde. The dimethoxymethane gas-liquid separation buffer for production of polyformaldehyde comprises a tank body which is provided with a liquidometer. The upper part of the tank body is connected with an exhaust pipe and the lower part of the tank body is connected with a three-way line pipe. The dimethoxymethane gas-liquid separation buffer for production of polyformaldehyde provided by the utility model is simple to prepare, low in cost, convenient to operate and remarkable in effect; can effectively discharge gas brought by raw materials; a space is reserved inside the upper part of the tank body to slow down the pressure oscillation of the raw materials, stabilize the flow of the raw materials and prevent performance of the final product from being affected.
Description
Technical field
The utility model belongs to polyformaldehyde plant-scale equipment technical field, is specifically related to a kind of polyformaldehyde production with dimethoxym ethane gas-liquid separation energy disperser.
Background technology
In the polyformaldehyde production process, need the liquid charging stock in the stock tank be carried with the form of nitrogen force feed, because raw material adopts the nitrogen force feed; And pipeline such as is provided with at a variety of causes; Liquid charging stock usually can have a part of gas in getting into course of conveying, the flow fluctuation that this can cause raw material is difficult to control; Have influence on various proportion of raw materials, directly cause the unstable properties of final product.
The utility model content
For overcoming the problem that exists in the prior art, the purpose of the utility model is to provide a kind of polyformaldehyde production of the flow fluctuation that can prevent raw material with dimethoxym ethane gas-liquid separation energy disperser.
For realizing above-mentioned purpose, the technical scheme that the utility model is taked is following:
The polyformaldehyde production of the utility model comprises tank body with dimethoxym ethane gas-liquid separation energy disperser, and liquidometer is housed on the tank body, and tank body top is connected with freeing pipe, and the bottom is connected with the threeway pipeline.
Preferably, freeing pipe is provided with the valve I, and second pipeline of threeway pipeline is provided with the valve III, and the 3rd pipeline is provided with the valve IV.
More preferably, be convenient maintenance, first pipeline of threeway pipeline is provided with the valve II.
The liquid level of the gas-liquid separation energy disperser in the utility model is controlled at 50 ~ 70%.
The utility model is made simple, and with low cost, easy to operate, effect is remarkable; Can discharge effectively in the raw material with gas; The space is left in the top in the tank body, can slow down the fluctuation of pressure of raw material, stablizes the flow of raw material, avoids having influence on the performance of final products.
Description of drawings
Fig. 1 is the scheme drawing of the utility model.
The specific embodiment
The polyformaldehyde production of the utility model is as shown in Figure 1 with dimethoxym ethane gas-liquid separation energy disperser, comprises tank body 1, and liquidometer 4 is housed on the tank body 1, and tank body 1 top is connected with freeing pipe 3, and freeing pipe 3 is provided with valve I 2.The tank body bottom is connected with threeway pipeline 6, and the second pipeline 6-2 of threeway pipeline is provided with valve III 5-2, and the 3rd pipeline 6-3 is provided with valve IV 5-3, is convenient maintenance, and the first pipeline 6-1 of threeway pipeline is provided with valve II 5-1.
The principle of work of the utility model is following:
During use,, the second pipeline 6-2 is connected stock tank at first with the 3rd pipeline 6-3 coupled reaction device; Open valve II 5-1, valve III 5-2 and valve I 2 then, valve-off IV 5-3, the stock tank warp second pipeline 6-2 is to tank body 1 nitrogen pressure liquor charging body raw material; 1 li liquid level of tank body reaches at 70% o'clock, and valve-off I 2 lets valve II 5-1 be in open mode all the time; Open valve IV 5-3 simultaneously, liquid charging stock is delivered to the conveying of accomplishing raw material in the reaction vessel through the 3rd pipeline 6-3.
When nitrogen extrudes liquid charging stock from stock tank; In the liquid charging stock with gas can enter into tank body 1; The gas that tank body is 1 li is under the pressure effect of liquid charging stock, and gas volume reduces, and pressure raises; When gaseous tension greater than threeway pipeline 6 in during the pressure of liquid charging stock, will the liquid charging stock of 1 li of tank body be pushed back in the threeway pipeline 6.Continuous like this have gas to get into tank body 1; Liquid charging stock in the tank body 1 is constantly got back in the threeway pipeline 6, when 1 li liquid level of tank body is lower than 50%, opens valve I 2; Gas is discharged; Make the liquid level of 1 li of tank body remain on 50 ~ 70%, then valve-off I 2 (because the high pressure effect of stock tank, liquid charging stock can not blow back in the stock tank).
