DT脫硫泵在嘅車前的準備工作

普通脫硫系統在開車前，先要停止試車實驗。DT脫硫泵脫硫系統檢修後，最少停止兩天水聯動試車，並對脫硫塔、迴圈槽停止清算。水聯動試車完畢後，察看噴頭及泵體運轉狀況，保證不梗塞噴頭避免梗塞。

DT脫硫泵降低對液氨的投入量，對脫硫塔停止整體的調整控制，確保脫硫塔出口煙氣穩定。同時控制脫硫塔pH值。將一、二級迴圈泵的入口過濾器換成管道過濾器，籃式過濾器密閉性差，雜質顆粒會梗塞噴頭，影響出料效果。

DT脫硫泵還能夠改良鍋爐除塵系統，普通運用較為普遍的是布袋除塵器，能夠用電袋複合式除塵來停止交換，確保煙氣之後的排放到達國度標準程度和環保請求，從而大大降低煙塵對系統產生的不利影響。

Before the start-up of ordinary desulfurization system， the test run experiment should be stopped first。 After the maintenance of desulfurization system， the water linkage test run shall be stopped for at least two days， and the desulfurization tower and circulating tank shall be stopped from clearing。 After the completion of the water linkage test run， check the operation condition of the nozzle and pump body to ensure that the nozzle is not blocked to avoid infarction。

Reduce the input of liquid ammonia， stop the overall adjustment and control of the desulfurization tower， and ensure the stability of flue gas at the outlet of the desulfurization tower。 Meanwhile， the pH value of desulfurization tower shall be controlled。 When the inlet filter of the primary and secondary circulating pumps is replaced by the pipeline filter， the basket filter has poor airtightness， and the impurity particles will block the nozzle and affect the discharge effect。

The utility model can also improve the dust removal system of the boiler。 The bag type dust remover is commonly used。 The utility model can stop the exchange by using the electric bag composite dust removal， so as to ensure that the emission of the flue gas reaches the national standard and the environmental protection requirements， thus greatly reducing the adverse impact of the flue gas on the system。
